    Use of heart failure medications in older individuals and associations with cognitive impairment2023Ingår i: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 23, nr 1, artikel-id 524Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: To achieve the best treatment of heart failure, it is important to use all recommended drugs at their target doses. Given that underuse of medications can occur in individuals with cognitive impairment, we investigated the filled prescriptions and target doses of heart failure medication for older individuals with and without cognitive impairment as well as associated factors.

    Methods: The study was based on two separate datasets. The first dataset, which was based on data from questionnaires sent to nursing homes in Sweden, included 405 individuals with heart failure. The data were linked with the Swedish Prescribed Drug Register and the National Patient Register to obtain information regarding filled prescriptions of heart failure medications and heart failure diagnoses among the population. In the second dataset, medical records of individuals aged 75 years or older admitted to a hospital in northern Sweden were reviewed and individuals with heart failure were identified. Target doses of heart failure medications were evaluated in 66 individuals who lived at home.

    Results: Filled prescriptions of mineralocorticoid receptor antagonists and loop diuretics were significantly more common in individuals without cognitive impairment (OR 1.087; 95% CI 1.026–1.152, p < 0.05) and (OR 1.057; 95% CI 1.017–1.098, p < 0.05), respectively. There were no significant differences between individuals with and without cognitive impairment in terms of achieving target doses for any of the drug classes. A higher age was associated with fewer filled prescriptions and less ability to reach the target doses of beta blockers (OR 0.950; 95% CI 0.918–0.984, p < 0.05) and (OR 0.781; 95% CI 0.645–0.946, p < 0.05), respectively.

    Conclusions: Our results suggest that individuals with cognitive impairment are partly undertreated for heart failure in that they had fewer filled prescriptions of important heart medications. Separately, the relatively low proportion of older individuals reaching target doses is an important observation and indicates that treatment of heart failure could be further optimised among older individuals.

    Histopathological and immunocytochemical studies in age-associated dementias: the importance of rigorous histopathological criteria for classification of progressive dementia disorders1985Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Dementia is an age-associated organic brain disorder, recogniz­able by the essential features of psychological or behavioral abnormality associated with permanent dysfunction of the brain interfering with social and occupational functioning.

    There are two clinical and three histopathological forms of dementia 1) primary degenerative dementia, (PDD), or Alzhei­mer's dementia/Senile dementia of Alzheimers type (AD/SDAT) which is associated with clinical features of uniform progres­sion and insidious onset of symptoms and histopathologically i- dentified by the occurrence of neurofibrillary tangles (NFT) and senile/neuritic plaques (SP/NP) in various cortical and subcor- tical regions; 2) vascular dementia, or multi-infarct dementia (MID), which is associated with clinical features of stepwise progress and patchy distribution of deficits, and histopatholo­gically identified by the occurrence of multiple large and/or small haemorrhagic and/or ischaemic infarcts in various cortical and subcortical regions and 3) intermediate form of dementia or "mixed” ("combined") dementia (AD-MID), which is histopatho- logically associated with the coexistance of symptoms and le­sions observed in AD/SDAT and MID, and clinically referred to the MID group. The DSM-III criteria separate the demented into two groups, AD/SDAT and MID, while there are no unique clinical criteria for the AD-MID patients. The clinical diagnosis of dementia according to the DSM-III criteria was shown to be in­sufficient . Histopathological diagnostic criteria were postu­lated by us for 1) pathological changes developing in mentallyunimpaired ageing, 2) AD/ SPAT, 3) MID and 4) AD-MID.

    These histopathological classes could be separated, by means of multivariate data analysis. The pathology in AD-MID was shown not to be merely a linear combination of the AD/SDATand MID pathology.

    Intrathecal synthesis of Ig, oligoclonal bands or other abnormal proteins in the CSF could not be demonstrated in aged non-demen- ted and demented patients.

    The blood-cerebrospinal barrier (B-CSF-B) or blood-brain barrier (BBB) function alters with age and this alteration was shown to be more pronounced in MID and AD-MID patients. In MID and AD-MID patients the BBB alteration involves primarily the grey matter while in AD/SDAT patients the alteration would appear to involve only the white matter. The BBB dysfunction and a possible complement activation, either through antibody-anti- gen activation or other complement activators, was visualized in MID and AD-MID patients as perivascular serum protein depo­sits in the grey matter, always with a capillary in the center. The occurrence of some serum proteins in plaques, and the previously descibed localization of plaques in close relation­ship to the capillaries, suggest that altered BBB function and serum factors may be involved in the etiology and maturation of plaques while the etiology and maturation of tangles may not be directly dependent on these factors, as they were never labelled with any of the antisera studied.

    Experiences of home as an aspect of well-being in people over 80 years: a mixed method study2022Ingår i: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 78, nr 1, s. 252-263Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aims: To (1) describe experiences of home from a well-being perspective, (2) describe participant characteristics and well-being measures in relation to housing type (3) and how the aforementioned aspects may affect well-being in very old persons.

    Design: Cross-sectional, convergent parallel-results mixed method design with semi-structured interviews analysed by qualitative content analysis, in relation to descriptive statistics and specific well-being outcome measures related to home.

    Methods: A total of 50 persons 80 years or older living in ordinary housing were interviewed (July 2017 to November 2018) about home in relation to well-being, along with collection of participant characteristics and well-being measures related to home.

    Results: Participants described how home had become increasingly important as it provided autonomy and acted as a social and occupational hub. However, autonomy was not unconditional, and home could also be perceived as a place of inactive solitude. Results were interpreted as relating to being in the margins of home and had a major impact on well-being. Housing type seemed of importance with higher measures of well-being for participants in single-living housing compared with those living in apartment.

    Conclusion: Home is increasingly central to well-being in old age; however, very old persons also have to relate to being physically and mentally in the margins of being able to remain in the home. These aspects of home potentially have a major impact on well-being.

    Impact: As very old persons living in ordinary housing will constitute a larger segment of society in coming years, aspects of home can potentially have a considerable impact on well-being for this age-group. This study describes aspects of home that contribute to, or has adverse impact on well-being. These aspects need thorough consideration in policy-making and planning of health care that can affect experiences of home.

    Accepting the inevitable: A mixed method approach with assessment and perceptions of well-being in very old persons within the northern Sweden Silver-MONICA study2021Ingår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 92, artikel-id 104275Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: As the group of very old persons will form an increasing part of society, the study of how well-being is described and affected by specific factors will be of importance to meet the future needs of these persons. The aim of the study was to increase knowledge of well-being in very old persons by combining assessments and perceptions using the Philadelphia Geriatric Morale Scale (PGCMS).

    Method: In a mixed method, convergent parallel design, 52 persons 80 years or older were assessed and interviewed using the PGCMS to combine assessment of morale and descriptions of perceptions of well-being using a mixed method approach.

    Results: Quantitative and qualitative results converged in four areas: not feeling lonely and being included, rating and perceiving health as good, high physical function/ability and being physically active, living in own house and feeling at home. Areas perceived as important to well-being captured only in qualitative analysis were having freedom and engagement. An example of insights not achievable from the quantitative or qualitative analysis alone was that individuals with high morale expressed anxiety about losing their health due to potential ageing-related threats and that individuals with low morale struggled with acceptance. Acceptance was the key strategy for handling adverse consequences of ageing in all described areas.

    Conclusion: When using standardized assessment scales in clinical practice, it could be useful to combine quantitative and qualitative data. Acceptance was key for well-being; however, acceptance could be resigned or reorienting in nature.

    Associations between everyday physical activity and morale in older adults2022Ingår i: Geriatric Nursing, ISSN 0197-4572, E-ISSN 1528-3984, Vol. 48, s. 37-42Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Studies that objectively investigate patterns of everyday physical activity in relation to well-being and that use measures specific to older adults are scarce. This study aimed to explore objectively measured everyday physical activity and sedentary behavior in relation to a morale measure specifically constructed for older adults. A total of 77 persons (42 women, 35 men) aged 80 years or older (84.3 ± 3.8) wore an accelerometer device for at least 5 days. Morale was measured with the Philadelphia Geriatric Center Morale Scale (PGCMS). PGCMS scores were significantly positively associated with number of steps, time spent stepping, and time spent stepping at >75 steps per minute. Sedentary behavior did not associate with PGCMS. Promoting PA in the form of walking at any intensity–or even spending time in an upright position—and in any quantity may be important for morale, or vice versa, or the influence may be bidirectional.

    Self-rated health in old age, related factors and survival: A 20-Year longitudinal study within the Silver-MONICA cohort2024Ingår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 122, artikel-id 105392Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: Self-rated health (SRH) offers insights into the evolving health demographics of an ageing population.

    Aim: To assess change in SRH from old age to very old age and their associations with health and well-being factors, and to investigate the association between SRH and survival.

    Methods: All participants in the MONICA 1999 re-examination born before 1940 (n = 1595) were included in the Silver-MONICA baseline cohort. The Silver-MONICA follow-up started in 2016 included participants in the Silver-MONICA baseline cohort aged 80 years or older. Data on SRH was available for 1561 participants at baseline with 446 of them also participating in the follow-up. The follow-up examination included a wide variety of measurements and tests.

    Findings: Most participants rated their health as "Quite good" (54.5 %) at baseline. Over the study period, 42.6 % had stable SRH, 40.6 % had declined, and 16.8 % had improved. Changes in SRH were at follow-up significantly associated with age, pain, nutrition, cognition, walking aid use, self-paced gait speed, lower extremity strength, independence in activities of daily living, weekly physical exercise, outdoor activity, participation in organized activities, visiting others, morale, and depressive symptoms. SRH at baseline was significantly associated with survival (p < 0.05).

    Conclusion: This study demonstrates associations between changes in SRH and a multitude of health- and wellbeing-related factors, as well as a relation between survival and SRH, accentuating their relevance within the ageing population.

    Constructions of various femininities among the oldest old women2006Ingår i: Health Care for Women International, ISSN 0739-9332, E-ISSN 1096-4665, Vol. 27, nr 10, s. 853-872Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study forms part of the Ume 85+ Study, and the aim was to explore various gendered constructions of femininities among the oldest old women. Femininities are seen as various ways of shaping oneself as a woman in relation to the impact of historical, social, and cultural circumstances. Thematic narratives were analyzed using qualitative content analysis. Through interpreting these narratives in the light of gender theories, we were able to discern four femininities: “being connected,” “being an actor,” “living in the shadow of others,” and “being alienated.” The oldest old women displayed complex outlooks on femininities, and no femininity was interpreted as being in the center related to the other femininities. Further research is needed in order to disclose the complexity of femininities related to factors such as social class, ethnicity, and financial situation among the oldest old, and to acquire a greater knowledge of various femininities.

    Glucose but not insulin or insulin resistance is associated with memory performance in middle-aged non-diabetic women: a cross sectional study2015Ingår i: Diabetology & Metabolic Syndrome, E-ISSN 1758-5996, Vol. 7, artikel-id 20Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Elevated concentrations of plasma glucose appear to play a role in memory impairment, and it has been suggested that insulin might also have a negative effect on cognitive function. Our aim was to study whether glucose, insulin or insulin resistance are associated with episodic or semantic memory in a non-diabetic and non-demented population. 

    Methods: We linked and matched two population-based data sets identifying 291 participants (127 men and 164 women, mean age of 50.7 +/- 8.0 years). Episodic and semantic memory functions were tested, and fasting plasma insulin, fasting plasma glucose, and 2-hour glucose were analysed along with other potential influencing factors on memory function. Since men and women display different results on memory functions they were analysed separately. Insulin resistance was calculated using the HOMA-IR method. 

    Results: A higher fasting plasma glucose concentration was associated with lower episodic memory in women (r = -0.08, 95% CI -0.14; -0.01), but not in men. Plasma insulin levels and insulin resistance were not associated with episodic or semantic memory in women or in men after adjustments for age, fasting glucose, 2-hour glucose, BMI, education, smoking, cardiovascular disease, hypertension, cholesterol, and physical activity. 

    Conclusions: This indicates that fasting glucose but not insulin, might have impact on episodic memory in middle-aged women.

    Embodying person-centred being and doing: leading towards person-centred care in nursing homes as narrated by managers2020Ingår i: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 29, nr 1-2, s. 172-183Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    AIMS AND OBJECTIVES: To explore how managers describe leading towards person-centred care in Swedish nursing homes.

    BACKGROUND: Although a growing body of research knowledge exists highlighting the importance of leadership to promote person-centred care, studies focused on nursing home managers' own descriptions of leading their staff towards providing person-centred care is lacking.

    DESIGN: Descriptive interview study. COREQ guidelines have been applied.

    METHODS: The study consisted of semi-structured interviews with 12 nursing home managers within 11 highly person-centred nursing homes purposively selected from a nationwide survey of nursing homes in Sweden. Data collection was performed in April 2017, and the data were analysed using content analysis.

    RESULTS: Leading towards person-centred care involved a main category; embodying person-centred being and doing, with four related categories: operationalising person-centred objectives; promoting a person-centred atmosphere; maximising person-centred team potential; and optimising person-centred support structures.

    CONCLUSIONS: The findings revealed that leading towards person-centred care was described as having a personal understanding of the PCC concept and how to translate it into practice, and maximising the potential of and providing support to care staff, within a trustful and innovative work place. The findings also describe how managers co-ordinate several aspects of care simultaneously, such as facilitating, evaluating and refining the translation of person-centred philosophy into synchronised care actions.

    RELEVANCE TO CLINICAL PRACTICE: The findings can be used to inspire nursing home leaders' practices and may serve as a framework for implementing person-centred care within facilities. A reasonable implication of these findings is that if organisations are committed to person-centred care provision, care may need to be organised in a way that enables managers to be present on the units, to enact these strategies and lead person-centred care.

    Physical activity, visceral adipose tissue, and cardiovascular disease in older adults: associations and effects2023Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    BACKGROUND: Cardiovascular disease (CVD) poses a substantial public health burden and is the leading cause of mortality in older adults. With the population aging rapidly, interventions aimed at improving modifiable risk factors for CVD, such as physical inactivity and visceral obesity, could play an important role in reducing its burden, provided they are proven effective.

    PURPOSE AND AIMS: The overall purpose of this thesis was to create a deeper understanding of the links between physical activity, visceral adipose tissue (VAT), and CVD in older adults, by studying it from both an observational and an interventional perspective. The specific aims were to investigate the associations of objectively measured physical activity and VAT with the risk of CVD and all-cause mortality, to investigate the effect of structured physical activity (exercise) on VAT, and to review the effects of exercise on CVD and all-cause mortality based on evidence from randomized controlled trials (RCTs).

    METHODS: This thesis comprised two prospective cohort studies, one RCT, and one narrative review of evidence from RCTs. The cohort studies included about 3,300 men and women aged 70 years with baseline data on physical activity and VAT mass, as obtained using accelerometry and dual-energy X-ray absorptiometry, respectively. Cases of stroke, myocardial infarction, and all-cause mortality during follow-up were collected from Swedish nationwide registers. The RCT included 77 men and women aged 70 years with visceral obesity who were randomly allocated to either 10 weeks of supervised vigorous-intensity exercise or to no exercise, with VAT mass measured before and after the intervention. In the review, evidence from published RCTs and meta-analyses of RCTs reporting on the effects of exercise on CVD (N=19,162) and all-cause mortality (N=37,443) in general older adults and in individuals with chronic conditions (such as obesity, type 2 diabetes, and preexisting CVD) were reviewed.

    MAIN FINDINGS: In the cohort studies, greater amounts of physical activity of any intensity, but especially that of moderate to vigorous intensity, were associated with lower risk of stroke, myocardial infarction, and all-cause mortality. Conversely, greater VAT mass was associated with higher risk of stroke or myocardial infarction. In the RCT, short-term vigorous-intensity exercise seemed to decrease VAT mass slightly, but the effect was not statistically significant. Finally, the review showed that there is currently no convincing evidence from RCTs that exercise effectively reduces the risk of CVD or all-cause mortality, which stands in sharp contrast to the strong associations typically reported in observational studies. The reasons for the conflicting findings are likely complex and multifactorial. In the RCTs, a lack of statistical power could partly explain why no effects have been detected in the general population of older adults, but it is unlikely to explain the null findings in clinical populations, as some of these trials, including meta-analyses of such trials, have been large. Other potential explanations could be a ceiling effect due to the inclusion of participants who were healthier and more physically active than the general population, or that an effect of exercise was masked by the use of effective medications such as antihypertensives and lipid-lowering agents. On the other hand, observational studies have likely overestimated the benefits of physical activity, because these studies are vulnerable to selection bias, reverse causation, and unmeasured confounding, such as from heritable influences.

    CONCLUSIONS AND IMPLICATIONS: Despite strong associations, the protective effect of physical activity as a single intervention against CVD and all-cause mortality in older adults is probably not as substantial as is commonly presumed. To uncover the true role of physical activity in preventing CVD, further high-quality trials would be valuable. However, because these trials are very difficult and resource demanding, they should be complemented by innovative observational studies that seek to strengthen causal inference through addressing sources of bias and confounding that are often incompletely accounted for in conventional observational studies. This could include a variety of methodologies, such as utilizing negative control outcomes, instrumental variables, sibling comparisons, and other genetically informed designs. As the aging population continues to grow, it becomes increasingly important to take these scientific steps in order to provide a more definitive answer to the question of the extent to which physical activity alone can reduce the risk of CVD.

    Association of dog ownership with accelerometer-measured physical activity and daily steps in 70-year-old individuals: a population-based cross-sectional study2021Ingår i: BMC Public Health, E-ISSN 1471-2458, Vol. 21, nr 1, artikel-id 2313Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Dog ownership (DO) has been associated with higher levels of self-reported walking and physical activity. However, compared to device-based measures, self-reported measures of physical activity may suffer from bias due to recall and social desirability. They are also incapable of quantifying light-intensity physical activity (LPA) and step volume, both of which may have important health benefits, especially for older adults. In this study, we investigated the association of DO with accelerometer-measured physical activity of different intensities and daily steps in 70-year-old individuals.

    Methods: This was a population-based cross-sectional study including 1406 participants aged 70 years [54.1% female] who participated in a health survey in Umeå, Sweden between February 2017–November 2019. All participants self-reported DO [yes/no]. Daily averages of LPA, moderate-to-vigorous-intensity physical activity (MVPA), and steps per day [steps/d] were measured for 1 week using hip-mounted Actigraph GT3X+ accelerometers. Associations were investigated using linear- and logistic regression models, adjusted for sociodemographic and health-related factors, date of examination, and accelerometer wear time.

    Results: The prevalence of DO was 14.1% [N = 199]. After adjustment for all covariates, DO was associated with 19.2 more minutes/d of LPA [95% CI, 8.8–29.6], 11.4 more minutes/d of MVPA [95% CI, 8.0–14.9] and 1738 more steps/d [95% CI, 1326–2149]. DO was also associated with twice the odds of meeting the physical activity recommendations [OR, 2.07, 95% CI, 1.48–2.90]. Exploratory interaction analyses showed that the association between DO and steps/d was stronger [Pinteraction = 0.030] in female [β = 2165, 95% CI, 1585–2744] than in male [β =1255, 95% CI, 664–1845], with a similar trend for MVPA [Pinteraction = 0.082].

    Conclusions: In this study of community-dwelling 70-year-old individuals, DO was associated with higher levels of daily LPA, MVPA, and steps. With the limitation of the observational design of the study, these findings add knowledge regarding the beneficial role that DO may play for promoting physical activity in the older population. In turn, these findings could support the development and evaluation of targeted interventions seeking to promote dog-friendly environments and facilitate dog walking in the community.

    Excess Mortality After COVID-19 in Swedish Long-Term Care Facilities2021Ingår i: Journal of the American Medical Directors Association, ISSN 1525-8610, E-ISSN 1538-9375, Vol. 22, nr 8, s. 1574-1580.e8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To compare 30-day mortality in long-term care facility (LTCF) residents with and without COVID-19 and to investigate the impact of 31 potential risk factors for mortality in COVID-19 cases.

    Design: Retrospective cohort study.

    Setting and Participants: All residents of LTCFs registered in Senior Alert, a Swedish national database of health examinations in older adults, during 2019-2020.

    Methods: We selected residents with confirmed COVID-19 until September 15, 2020, along with time-dependent propensity score–matched controls without COVID-19. Exposures were COVID-19, age, sex, comorbidities, medications, and other patient characteristics. The outcome was all-cause 30-day mortality.

    Results: A total of 3731 residents (median age 87 years, 64.5% female) with COVID-19 were matched to 3731 controls without COVID-19. Thirty-day mortality was 39.9% in COVID-19 cases and 5.7% in controls [relative risk 7.05, 95% confidence interval (CI) 6.10-8.14]. In COVID-19 cases, the odds ratio (OR) for 30-day mortality was 2.44 (95% CI 1.57-3.81) in cases aged 80-84 years, 2.99 (95% CI 1.93-4.65) in cases aged 85-89 years, and 3.28 (95% CI 2.11-5.10) in cases aged ≥90 years, as compared with cases aged <70 years. Other risk factors for mortality among COVID-19 cases included male sex (OR, 2.60, 95% CI 2.22-3.05), neuropsychological conditions (OR, 2.18; 95% CI 1.76-2.71), impaired walking ability (OR, 1.45, 95% CI 1.17-1.78), urinary and bowel incontinence (OR 1.51, 95% CI 1.22-1.85), diabetes (OR 1.36, 95% CI 1.14-1.62), chronic kidney disease (OR 1.37, 95% CI 1.11-1.68) and previous pneumonia (OR 1.57, 95% CI 1.32-1.85). Nutritional factors, cardiovascular diseases, and antihypertensive medications were not significantly associated with mortality.

    Conclusions and Implications: In Swedish LTCFs, COVID-19 was associated with a large excess in mortality after controlling for an extensive number of risk factors. Beyond older age and male sex, several prevalent clinical risk factors independently contributed to higher mortality. These findings suggest that reducing transmission of COVID-19 in LTCFs will likely prevent a considerable number of deaths.

    Digital exercise interventions for improving measures of central obesity: a systematic review2020Ingår i: International Journal of Public Health, ISSN 1661-8556, E-ISSN 1661-8564, Vol. 65, nr 5, s. 593-605Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Objectives: We aimed to systematically review the potential benefits of digital exercise interventions for improving measures of central obesity including visceral adipose tissue (VAT) and anthropometric surrogates for VAT in overweight or centrally obese adults aged 18 or over.

    Methods: A systematic literature search was conducted in three databases up until March 2020 (PROSPERO registration nr CRD42019126764).

    Results: N = 5 studies including 438 participants (age 48–80) with body mass index ≥ 25 kg/m2 met the eligibility criteria and were included. The duration of the interventions ranged from 8 to 24 weeks. No study measured the primary outcome VAT, although in N = 4 studies, waist circumference (WC) decreased by between 1.3 and 5.6 cm in the intervention groups.

    Conclusions: This systematic review shows that there is no evidence for the effects of digital exercise on VAT, although digital exercise may decrease WC. These findings highlight the need for additional randomized controlled trials to confirm the findings with respect to WC, and to further investigate the effects of digital exercise on VAT. Together, this may have important implications for reducing the burden of physical inactivity and obesity.

    Web-based exercise versus supervised exercise for decreasing visceral adipose tissue in older adults with central obesity: a randomized controlled trial2020Ingår i: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 20, nr 1, artikel-id 173Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Visceral adipose tissue (VAT) is a strong risk factor for cardiovascular disease and increases with age. While supervised exercise (SE) may be an effective approach, web-based exercise (WE) have other advantages such as being more readily accessible. Therefore, we evaluated the effects of WE on VAT, body composition and cardiometabolic risk markers in centrally obese older adults and compared the effects of WE to SE. We also explored the feasibility of WE.

    METHODS: In a randomized controlled trial conducted in Umeå, Sweden during January 2018 - November 2018, N = 77, 70-year-old men and women with central obesity (> 1 kg VAT for women, > 2 kg for men) were randomized to an intervention group (n = 38) and a wait-list control group (n = 39). The intervention group received 10 weeks of SE while the wait-list control group lived as usual. Following a 10-week wash-out-period, the wait-list control group received 10 weeks of WE. The primary outcome was changes in VAT. Secondary outcomes included changes in fat mass (FM), lean body mass (LBM), blood lipids, fasting blood glucose. Additionally, we explored the feasibility of WE defined as adherence and participant experiences.

    RESULTS: WE had no significant effect on VAT (P = 0.5), although it decreased FM by 450 g (95% confidence interval [CI], 37 to 836, P < 0.05). The adherence to WE was 85% and 87-97% of the participants rated aspects of the WE intervention > 4 on a scale of 1-5. Comparing SE to WE, there was no significant difference in decrease of VAT (Cohen's δ effect size [ES], 0.5, 95% CI, - 24 to 223, P = 0.11), although SE decreased FM by 619 g (ES, 0.5, 95% CI, 22 to 1215, P < 0.05) compared to WE.

    CONCLUSIONS: Ten weeks of vigorous WE is insufficient to decrease VAT in centrally obese older adults, but sufficient to decrease FM while preserving LBM. The high adherence and positive experiences of the WE intervention implies that it could serve as an alternative exercise strategy for older adults with central obesity, with increased availability for a larger population.

    Time-varying risk of death after SARS-CoV-2 infection in Swedish long-term care facility residents: a matched cohort study2022Ingår i: BMJ Open, E-ISSN 2044-6055, Vol. 12, nr 11, artikel-id e066258Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: To evaluate whether SARS-CoV-2 infection in residents of long-term care (LTC) facilities is associated with higher mortality after the acute phase of infection, and to estimate survival in uninfected residents.

    DESIGN: Extended follow-up of a previous, propensity score-matched, retrospective cohort study based on the Swedish Senior Alert register.

    SETTING: LTC facilities in Sweden.

    PARTICIPANTS: n=3604 LTC residents with documented SARS-CoV-2 until 15 September 2020 matched to 3604 uninfected controls using time-dependent propensity scores on age, sex, health status, comorbidities, prescription medications, geographical region and Senior Alert registration time. In a secondary analysis (n=3731 in each group), geographical region and Senior Alert registration time were not matched for in order to increase the follow-up time in controls and allow for an estimation of median survival.

    PRIMARY OUTCOME MEASURES: All-cause mortality until 24 October 2020, tracked using the National Cause of Death Register.

    RESULTS: Median age was 87 years and 65% were women. Excess mortality peaked at 5 days after documented SARS-CoV-2-infection (HR 21.5, 95% CI 15.9 to 29.2), after which excess mortality decreased. From the second month onwards, mortality rate became lower in infected residents than controls. The HR for death during days 61-210 of follow-up was 0.76 (95% CI 0.62 to 0.93). The median survival of uninfected controls was 1.6 years, which was much lower than the national life expectancy in Sweden at age 87 (5.05 years in men, 6.07 years in women).

    CONCLUSIONS: The risk of death after SARS-CoV-2 infection in LTC residents peaked after 5 days and decreased after 2 months, probably because the frailest residents died during the acute phase, leaving healthier residents remaining. The limited life expectancy in this population suggests that LTC resident status should be accounted for when estimating years of life lost due to COVID-19.

    Effects of interval training on quality of life and cardiometabolic risk markers in older adults: a randomized controlled trial2019Ingår i: Clinical Interventions in Aging, ISSN 1176-9092, E-ISSN 1178-1998, Vol. 14, s. 1589-1599Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: To explore the effects of 10 weeks of progressive vigorous interval training as a single intervention on health-related quality of life (HRQoL) and cardiometabolic risk markers in centrally obese 70-year-old individuals.

    Participants and methods: A randomized controlled trial (ClinicalTrials.gov registration no. NCT03450655) including seventy-seven community-dwelling 70-year-old men and women with central obesity defined as > 1 kg visceral adipose tissue for women and > 2 kg for men. Participants randomized to the intervention group were offered a 10-week progressive vigorous interval training program performed three times per week. Control subjects were asked to maintain their daily living and routines throughout the trial. All participants in both groups had received tailored lifestyle recommendations focused on diet and physical activity at one occasion within 12 months prior to trial initiation. Prespecified outcome measures included: changes in HRQoL using the Short Form Health Survey Questionnaire (SF-36), blood pressure; resting heart rate (HR) and blood lipids. All analyses were conducted on an intention-to-treat basis.

    Results: The intervention resulted in significant effects on the SF-36 mental component summary (MCS) score and the mental health (MH) subscale (P< 0.05 for both), when compared to the control group. Specifically, the intervention group increased their MCS score by 6.3 points (95% confidence interval [CI] = 0.3–12.3) and their MH score by 6.0 points (95% CI = 1.7–10.4) compared to the control group. Moreover, significant effects were seen on resting HR, total cholesterol and LDL-cholesterol (P<0.05 for all).

    Conclusion: It was shown that 10 weeks of vigorous interval training as a single intervention was sufficient to improve mental aspects of HRQoL in older individuals with central obesity, which is a critical aspect of healthy ageing. Positive effects were seen also on cardiometabolic risk markers.

    Effects of Interval Training on Visceral Adipose Tissue in Centrally Obese 70-Year-Old Individuals: A Randomized Controlled Trial2019Ingår i: Journal of The American Geriatrics Society, ISSN 0002-8614, E-ISSN 1532-5415, Vol. 67, nr 8, s. 1625-1631Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To investigate the effects of 10 weeks of progressive vigorous-intensity interval training as a single intervention on body composition among 70-year-old individuals with central obesity.

    DESIGN: Randomized controlled trial (ClinicalTrials.gov registration No. NCT03450655).

    SETTING: Community-dwelling 70-year-old men and women living in the Umeå municipality in Sweden.

    PARTICIPANTS: Seventy-seven 70-year-old men and women with central obesity (greater than 1 kg visceral adipose tissue [VAT] for women and greater than 2 kg VAT for men).

    INTERVENTION: Participants allocated to the intervention group were offered a 10-week progressive concurrent exercise program performed three times per week. All participants in both groups had received tailored lifestyle recommendations focused on diet and physical activity at one occasion within 12 months prior to trial initiation.

    MEASUREMENTS: The primary outcome was changes in VAT, and secondary outcomes included changes in total fat mass (FM), total lean body mass (LBM), and body mass index.

    RESULTS: Comparing the groups, there were no significant differences in decrease of VAT mass (P = .10), although the intervention group significantly decreased FM by 716 g (P = .01) and gained LBM by 508 g (P = .03), compared to the control group. Furthermore, the effects of the training were significantly greater in the male subcohort (P < .05 for interaction), with positive effects also on VAT and FM, where men in the intervention group decreased VAT by 175 g (P < .05) and FM by 1364 g (P = .004), compared to the male controls.

    CONCLUSIONS: The present trial demonstrates that 10 weeks of progressive vigorous interval training is sufficient to significantly decrease FM in older adults with central obesity, with positive effects also on LBM.

    Cardiovascular Disease and All-Cause Mortality in Male Twins with Discordant Cardiorespiratory Fitness: A Nationwide Cohort Study2020Ingår i: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 189, nr 10, s. 1114-1123Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Whether genetic and familial factors influence the association between cardiorespiratory fitness (CRF) and cardiovascular disease (CVD) is unknown. Two cohorts were formed based on 1,212,295, 18-year-old men that conscripted for military service in Sweden 1972-1996. The first comprised 4,260 twin pairs where twins in each pair had different CRF (≥1 Watt). The second comprised 90,331 non-sibling pairs with different CRF and matched on birth year and year of conscription. Incident CVD and all-cause mortality were identified using national registers. During follow-up (median 32 years), there was no difference in CVD and mortality between fitter twins and less fit twins (246 vs 251 events; hazard ratio [HR] = 1.00, 95% confidence interval [CI]: 0.83, 1.20). The risks were similar in twin pairs with ≥60 Watt difference in CRF (HR = 0.96, 95% CI: 0.57, 1.64). In contrast, in the non-sibling cohort, fitter men had a lower risk of the outcomes than less fit men (4444 vs 5298 events; HR = 0.87, 95% CI: 0.83, 0.92). The association was stronger in pairs with ≥60 Watt difference in CRF (HR = 0.65, 95% CI: 0.59, 0.71). These findings indicate that genetic and familial factors influence the association of CRF with CVD and mortality.

    Does exercise prevent major non-communicable diseases and premature mortality?: A critical review based on results from randomized controlled trials2021Ingår i: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 290, nr 6, s. 1112-1129Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Observational studies show that physical activity is strongly associated with a reduced risk of premature mortality and major non-communicable diseases. We reviewed to which extent these associations have been confirmed in randomized controlled trials (RCTs) for the outcomes of mortality, cardiovascular disease (CVD), type 2 diabetes (T2D), and fracture. The results show that exercise does not reduce all-cause mortality and incident CVD in older adults or in people with chronic conditions, based on RCTs comprising ∼50,000 participants. The results also indicate a lack of effect on cardiovascular mortality in people with chronic conditions, based on RCTs comprising ∼11,000 participants. Furthermore, there is inconsistent evidence regarding the effect of exercise on fractures in older adults, based on RCTs comprising ∼40,000 participants. Finally, based on RCTs comprising ∼17,000 participants, exercise reduces T2D incidence in people with prediabetes when combined with dietary modification, although evidence for the individual effect of exercise is lacking. Identified shortcomings of the current evidence include risks of publication bias, lack of high-quality studies in certain high-risk populations, and inconstant evidence with respect to some outcomes. Thus, additional large trials would be of value, especially with fracture as the primary outcome. In conclusion, according to current RCT evidence, exercise can prevent T2D assuming it is combined with dietary intervention. However, the current evidence shows that exercise does not prevent premature mortality or CVD, with inconsistent evidence for fractures.

    Daily step count and incident diabetes in community-dwelling 70-year-olds: a prospective cohort study2020Ingår i: BMC Public Health, E-ISSN 1471-2458, Vol. 20, nr 1, artikel-id 1830Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Older adults with diabetes take fewer steps per day than those without diabetes. The purpose of the present study was to investigate the association of daily step count with incident diabetes in community-dwelling 70-year-olds.

    Methods: This prospective cohort study included N = 3055 community-dwelling 70-year-olds (52% women) who participated in a health examination in Umeå, Sweden during 2012–2017, and who were free from diabetes at baseline. Daily step count was measured for 1 week using Actigraph GT3X+ accelerometers. Cases of diabetes were collected from the Swedish National Patient Register. The dose-response association was evaluated graphically using a flexible parametric model, and hazard ratios (HR) with 95% confidence intervals (CI) were calculated using Cox regressions.

    Results: During a mean follow-up of 2.6 years, diabetes was diagnosed in 81 participants. There was an inverse nonlinear dose-response association between daily step count and incident diabetes, with a steep decline in risk of diabetes from a higher daily step count until around 6000 steps/day. From there, the risk decreased at a slower rate until it leveled off at around 8000 steps/day. A threshold of 4500 steps/day was found to best distinguish participants with the lowest risk of diabetes, where those taking ≥ 4500 steps/day, had 59% lower risk of diabetes, compared to those taking fewer steps (HR, 0.41, 95% CI, 0.25–0.66). Adjusting for visceral adipose tissue (VAT) attenuated the association (HR, 0.64, 95% CI, 0.38–1.06), which was marginally altered after further adjusting for sedentary time, education and other cardiometabolic risk factors and diseases (HR, 0.58, 95% CI, 0.32–1.05).

    Conclusions: A higher daily step count is associated with lower risk of incident diabetes in community-dwelling 70-year-olds. The greatest benefits occur at the lower end of the activity range, and much earlier than 10,000 steps/day. With the limitation of being an observational study, these findings suggest that promoting even a modest increase in daily step count may help to reduce the risk of diabetes in older adults. Because VAT appears to partly mediate the association, lifestyle interventions targeting diabetes should apart from promoting physical activity also aim to prevent and reduce central obesity.

    Associations of Objectively Measured Physical Activity and Sedentary Time with the Risk of Stroke, Myocardial Infarction or All‑Cause Mortality in 70‑Year‑Old Men and Women: A Prospective Cohort Study2020Ingår i: Sports Medicine, ISSN 0112-1642, E-ISSN 1179-2035, Vol. 51, nr 2, s. 339-349Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To study the associations of objectively measured physical activity (PA) and sedentary time (ST) with the combined outcome of incident stroke, myocardial infarction (MI) or all-cause mortality in older adults.

    Methods: N = 3343 men and women aged 70 who participated in a health survey between 2012 and 2017 were included. Actigraph GT3X+ accelerometers were used to measure light-intensity PA (LPA), moderate-intensity PA (MPA) and ST for 1 week. Incident cases of cardiovascular disease (CVD) in terms of stroke or MI, and all-cause mortality were identified using national registers. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using multivariable-adjusted Cox regressions.

    Results: During a mean follow-up of 2.7 years (0.1–5.6), there were 124 events of CVD or all-cause mortality. After adjusting for potential confounders and mediators, every 30-min/day increment in LPA was associated with 11% lower risk of CVD or all-cause mortality (HR 0.89, 95% CI 0.82–0.97), and every 30-min/day increment in MPA was associated with 36% lower risk (HR 0.64, 95% CI 0.48–0.84). Every 1-h/day increment in ST increased the risk of the outcomes by 33% (HR 1.33, 95% CI 1.14–1.56), although there was no significant association among participants who performed ≥ 30 min/day MPA (HR 1.11, 95% CI 0.82–1.50, P = 0.034 for interaction). None of the associations were modified by sex (P > 0.4 for all).

    Conclusion: Objectively measured LPA and MPA are each associated with lower risk of stroke, MI or all-cause mortality in 70-year-old individuals, while ST is associated with increased risk. The greatest risk reduction is observed for MPA, which also appears to attenuate some of the increased risks associated with ST.

    Associations of visceral adipose tissue and skeletal muscle density with incident stroke, myocardial infarction, and all-cause mortality in community-dwelling 70-year-old individuals: A prospective cohort study2021Ingår i: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, ISSN 2047-9980, E-ISSN 2047-9980, Vol. 10, nr 9, artikel-id e020065Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Aging leads to increased visceral adipose tissue (VAT) and reduced skeletal muscle density. To which extent these are associated with the risk of stroke, myocardial infarction (MI), and all-cause mortality in older adults is unknown.

    METHODS AND RESULTS: A total of 3294 70-year-old individuals (49.6% women) underwent a health examination in Umeå, Sweden, during 2012 to 2018. VAT and muscle density were measured using dual-energy x-ray absorptiometry and peripheral quantitative computed tomography. Cases of stroke, MI, and all-cause mortality were collected through national registers. Cox regressions were used to calculate hazard ratios (HRs) and 95% CIs per SD greater VAT and per SD lower muscle density. During a mean follow-up of 3.6 years, there were 108 cases of stroke or MI, and 97 deaths. Greater VAT (adjusted HR [aHR], 1.56; 95% CI, 1.09– 2.22), but not lower muscle density (aHR, 1.14; 95% CI, 0.97–1.34), was associated with increased risk of stroke or MI. Neither VAT (aHR, 0.95; 95% CI, 0.65–1.41) nor muscle density (aHR, 1.11; 95% CI, 0.92–1.34) was associated with all-cause mortality. The association of VAT with stroke or MI was only significant in men (aHR, 1.86; 95% CI, 1.19– 2.91) but not women (aHR, 0.60; 95% CI, 0.25–1.42) (Pinteraction =0.038).

    CONCLUSIONS: With the limitation of being an observational study, these findings suggest that VAT is an important obesity-related predictor of cardiovascular risk in 70-year-old men, and by implication, that decreasing VAT may potentially reduce their risk of cardiovascular disease.

    Associations of light, moderate to vigorous, and total physical activity with the prevalence of metabolic syndrome in 4,652 community-dwelling 70-year-olds: A population-based cross-sectional study2021Ingår i: Journal of Aging and Physical Activity, ISSN 1063-8652, E-ISSN 1543-267X, Vol. 29, nr 5, s. 735-743Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this cross-sectional study, the authors investigated the associations of objectively measured physical activity (PA) with the prevalence of metabolic syndrome (MetS) in older adults. Accelerometer-derived light-intensity PA, moderate to vigorous PA, and steps per day were measured in (N = 4,652) 70-year-olds in Umeå, Sweden, during May 2012-November 2019. The MetS was assessed according to the American Heart Association/National Heart, Lung and Blood Institute criteria. The prevalence of MetS was 49.3%. Compared with the reference, the odds ratios for MetS in increasing quartiles of light-intensity PA were 0.91 (0.77-1.09), 0.75 (0.62-0.89), and 0.66 (0.54-0.80). For moderate to vigorous PA, the corresponding odds ratios were 0.79 (0.66-0.94), 0.67 (0.56-0.80), and 0.56 (0.46-0.67). For steps per day, the odds ratios were 0.65 (0.55-0.78), 0.55 (0.46-0.65), and 0.45 (0.36-0.55). In summary, this study shows that greater amounts of PA, regardless of intensity, are associated with lower odds of MetS. With the limitation of being an observational study, these findings may have implications for the prevention of MetS in older adults.

    Self-rated health and all-cause and cause-specific mortality of older adults: Individual data meta-analysis of prospective cohort studies in the CHANCES Consortium2017Ingår i: Maturitas, ISSN 0378-5122, E-ISSN 1873-4111, Vol. 103, s. 37-44Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To evaluate, among the elderly, the association of self-rated health (SRH) with mortality, and to identify determinants of self-rating health as “at-least-good”.

    Study design: Individual data on SRH and important covariates were obtained for 424,791 European and United States residents, ≥60 years at recruitment (1982–2008), in eight prospective studies in the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES). In each study, adjusted mortality ratios (hazard ratios, HRs) in relation to SRH were calculated and subsequently combined with random-effect meta-analyses.

    Main outcome measures: All-cause, cardiovascular and cancer mortality.

    Results: Within the median 12.5 years of follow-up, 93,014 (22%) deaths occurred. SRH “fair” or “poor” vs. “at-least-good” was associated with increased mortality: HRs 1.46 (95% CI 1·23–1.74) and 2.31 (1.79–2.99), respectively. These associations were evident: for cardiovascular and, to a lesser extent, cancer mortality, and within-study, within-subgroup analyses. Accounting for lifestyle, sociodemographic, somatometric factors and, subsequently, for medical history explained only a modest amount of the unadjusted associations. Factors favourably associated with SRH were: sex (males), age (younger-old), education (high), marital status (married/cohabiting), physical activity (active), body mass index (non-obese), alcohol consumption (low to moderate) and previous morbidity (absence).

    Conclusion: SRH provides a quick and simple tool for assessing health and identifying groups of elders at risk of early mortality that may be useful also in clinical settings. Modifying determinants of favourably rating health, e.g. by increasing physical activity and/or by eliminating obesity, may be important for older adults to “feel healthy” and “be healthy”.

    The thriving of older people assessment scale: Psychometric evaluation and short‐form development2019Ingår i: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 75, nr 12, s. 3831-3843Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To evaluate the psychometric properties and performance of the 32‐item Thriving of Older People Assessment Scale (TOPAS) and to explore reduction into a short‐form.

    Background: The 32‐item TOPAS has been used in studies of place‐related well‐being as a positive measure in long‐term care to assess nursing home resident thriving; however, item redundancy has not previously been explored.

    Design: Cross‐sectional.

    Method: Staff members completed the 32‐item TOPAS as proxy‐raters for a random sample of Swedish nursing home residents (N = 4,831) between November 2013 and September 2014. Reliability analysis, exploratory factor analysis and item response theory‐based analysis were undertaken. Items were systematically identified for reduction using statistical and theoretical analysis. Correlation testing, means comparison and model fit evaluation confirmed scale equivalence.

    Results: Psychometric properties of the 32‐item TOPAS were satisfactory and several items were identified for scale reduction. The proposed short‐form TOPAS exhibited a high level of internal consistency (α=0.90) and strong correlation (r=0.98) to the original scale, while also retaining diversity among items in terms of factor structure and item difficulties.

    Conclusion: The 32‐item and short‐form TOPAS' indicated sound validity and reliability to measure resident thriving in the nursing home context.

    Impact: There is a lack of positive life‐world measures for use in nursing homes. The short‐form TOPAS indicated sound validity and reliability to measure resident thriving, providing a feasible measure with enhanced functionality for use in aged care research, assessments and care planning for health promoting purposes in nursing homes.

    Duration of Postoperative Delirium Is an Independent Predictor of 6-Month Mortality in Older Adults After Hip Fracture2014Ingår i: Journal of The American Geriatrics Society, ISSN 0002-8614, E-ISSN 1532-5415, Vol. 62, nr 7, s. 1335-1340Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: To evaluate the association between number of days with delirium and 6-month mortality in elderly adults after hip fracture surgery. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: Orthogeriatric Unit (OGU). PARTICIPANTS: Individuals (mean age = 84.3 +/- 6.4) admitted to the OGU between October 2011 and April 2013 with hip fracture (N = 199). MEASUREMENTS: Postoperative delirium (POD) was assessed daily using the Confusion Assessment Method algorithm and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria. Multivariable Cox regression models were used to evaluate the association between POD of and 6-month mortality after surgery, after adjustment for covariates including age, prefracture residence, Katz activity of daily living score, New Mobility score, diagnosis of prefracture dementia, American Society of Anesthesiologists score, albumin serum levels, Charlson Comorbidity Index, and length of OGU stay. RESULTS: Fifty-seven participants (28.6%) developed POD. In the 6-month period after surgery, 35 (17.6%) participants died: 16 of 57 (28.1%) with POD and 19 / of 142 (13.4%) with no POD. The average duration of POD was 2.0 +/- 3.2 days for participants who died and 0.7 +/- 1.8 days for those who survived (P < .001). After adjusting for covariates, each day of POD in the OGU increased the hazard of dying at 6 months by 17% (hazard ratio = 1.17, 95% confidence interval = 1.07-1.28). CONCLUSION: In older adults undergoing hip fracture surgery, duration of POD is an important prognostic factor for 6-month mortality. Efforts to reduce duration of POD are therefore crucial for these individuals.

    Mediterranean diet and hip fracture incidence among older adults: the CHANCES project2018Ingår i: Osteoporosis International, ISSN 0937-941X, E-ISSN 1433-2965, Vol. 29, nr 7, s. 1591-1599Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The association between adherence to Mediterranean diet (MD) and hip fracture incidence is not yet established. In a diverse population of elderly, increased adherence to MD was associated with lower hip fracture incidence. Except preventing major chronic diseases, adhering to MD might have additional benefits in lowering hip fracture risk.

    INTRODUCTION: Hip fractures constitute a major public health problem among older adults. Latest evidence links adherence to Mediterranean diet (MD) with reduced hip fracture risk, but still more research is needed to elucidate this relationship. The potential association of adherence to MD with hip fracture incidence was explored among older adults.

    METHODS: A total of 140,775 adults (116,176 women, 24,599 men) 60 years and older, from five cohorts from Europe and the USA, were followed-up for 1,896,219 person-years experiencing 5454 hip fractures. Diet was assessed at baseline by validated, cohort-specific, food-frequency questionnaires, and hip fractures were ascertained through patient registers or telephone interviews/questionnaires. Adherence to MD was evaluated by a scoring system on a 10-point scale modified to be applied also to non-Mediterranean populations. In order to evaluate the association between MD and hip fracture incidence, cohort-specific hazard ratios (HR), adjusted for potential confounders, were estimated using Cox proportional-hazards regression and pooled estimates were subsequently derived implementing random-effects meta-analysis.

    RESULTS: A two-point increase in the score was associated with a significant 4% decrease in hip fracture risk (pooled adjusted HR 0.96; 95% confidence interval (95% CI) 0.92-0.99, pheterogeneity = 0.446). In categorical analyses, hip fracture risk was lower among men and women with moderate (HR 0.93; 95% CI 0.87-0.99) and high (HR 0.94; 95% CI 0.87-1.01) adherence to the score compared with those with low adherence.

    CONCLUSIONS: In this large sample of older adults from Europe and the USA, increased adherence to MD was associated with lower hip fracture incidence.

    Depression among the very old with dementia2011Ingår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 23, nr 5, s. 756-763Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: The aim of this study was to investigate the prevalence of depression among very old individuals with dementia compared to those without dementia and to examine if there were any differences regarding associated factors between people with or without depression in these conditions.

    Methods: In a population-based study in Sweden, 363 participants aged 85 years and above, were evaluated for depression and dementia.

    Results: The prevalence of depression was significantly higher among the people with dementia than without dementia, 43% vs. 24% (p < 0.001). Approximately 2/3 of the depressed in both groups used antidepressants and of those, approximately 50% had responded. Depression in the group without dementia was, among other factors, associated with higher total number of medication, the use of significant more analgesics and benzodiazepines, loneliness, inability of going outside and recent loss of child. The loss of a child was the only factor that was independently associated with depression in those with dementia.

    Conclusions: The present study confirms that in the very old, depression is more common among people with dementia than without dementia. A large proportion, both with and without dementia, are under-diagnosed and untreated, and in addition many subjects in both groups studied were non-responders to treatment. Many of the factors associated with depression among people without dementia in this study were not associated with depression among those with dementia, thus supporting the theory that the spectrum of associated factors for depression in dementia seems to be different from that for depression in people without dementia.

    Having plans for the future in very old people2024Ingår i: The International Journal of Aging & Human Development, ISSN 0091-4150, E-ISSN 1541-3535Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aimed to investigate the prevalence of having plans for the future among very old people and the factors associated with having such plans. A longitudinal population-based study with home visits for 85-, 90-, and ≥95-year-old participants in Sweden and Finland was used. Multivariate logistic regression and Cox proportional-hazards regression models with a maximum 5-year follow-up period were used. The prevalence of having plans for the future was 18.6% (174/936). More men than women and more people living in Sweden than in Finland had plans for the future. In multivariate models, having plans for the future was associated with speaking Swedish, being dentate, and living in the community in the total sample; speaking Swedish and being dentate among women; and speaking Swedish, having a lower Geriatric Depression Scale score, and urban residence among men. Having plans for the future was associated univariately, but not multivariately, with increased survival.

    Effects of geriatric interdisciplinary home rehabilitation on complications and readmissions after hip fracture: a randomized controlled trial2019Ingår i: Clinical Rehabilitation, ISSN 0269-2155, E-ISSN 1477-0873, Vol. 33, nr 1, s. 64-73Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: This pre-planned secondary analysis of geriatric interdisciplinary home rehabilitation, which was initially found to shorten the postoperative length of stay in hospital for older individuals following hip fracture, investigated whether such rehabilitation reduced the numbers of complications, readmissions, and total days spent in hospital after discharge during a 12-month follow-up period compared with conventional geriatric care and rehabilitation.

    Design: Randomized controlled trial.

    Setting: Geriatric department, participants' residential care facilities, and ordinary housing.

    Subjects: Individuals aged ⩾70 years with acute hip fracture (n = 205) were included.

    Intervention: Geriatric interdisciplinary home rehabilitation was individually designed and aimed at early discharge with the intention to prevent, detect, and treat complications after discharge.

    Main measures: Complications, readmissions, and days spent in hospital were registered from patients' digital records and interviews conducted during hospitalization and at 3- and 12-month follow-up visits.

    Results: No significant difference in outcomes was observed. Between discharge and the 12-month follow-up, among participants in the geriatric interdisciplinary home rehabilitation group (n = 106) and control group (n = 93), 57 (53.8%) and 44 (47.3%) had complications (P = 0.443), 46 (43.4%) and 38 (40.9%) fell (P = 0.828), and 38 (35.8%) and 27 (29.0%) were readmitted to hospital (P = 0.383); the median total days spent in hospital were 11.5 and 11.0 (P = 0.353), respectively.

    Conclusion: Geriatric interdisciplinary home rehabilitation for older individuals following hip fracture resulted in similar proportions of complications, readmissions, and total days spent in hospital after discharge compared with conventional geriatric care and rehabilitation.

    Co-morbidities, complications and causes of death among people with femoral neck fracture: a three-year follow-up study2016Ingår i: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 16, artikel-id 120Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The poor outcome after a hip fracture is not fully understood. The aim of the study was to describe the prevalence of co-morbidities, complications and causes of death and to investigate factors that are able to predict mortality in old people with femoral neck fracture. Methods: Data was obtained from a randomized, controlled trial with a 3-year follow-up at Umea University Hospital, Sweden, which included 199 consecutive patients with femoral neck fracture, aged >= 70 years. The participants were assessed during hospitalization and in their homes 4, 12 and 36 months after surgery. Medical records and death certificates were analysed. Results: Multivariate analysis revealed that cancer, dependence in P-ADL (Personal Activities of Daily Living), cardiovascular disease, dementia at baseline or pulmonary emboli or cardiac failure during hospitalization were all independent predictors of 3-year mortality. Seventy-nine out of 199 participants (40 %) died within 3 years. Cardiovascular events (24 %), dementia (23 %), hip-fracture (19 %) and cancer (13 %) were the most common primary causes of death. In total, 136 participants suffered at least one urinary tract infection; 114 suffered 542 falls and 37 sustained 56 new fractures, including 13 hip fractures, during follow-up. Conclusion: Old people with femoral neck fracture have multiple co-morbidities and suffer numerous complications. Thus randomized intervention studies should focus on prevention of complications that might be avoidable such as infections, heart diseases, falls and fractures.

    Evaluation of a fall-prevention program in older people after femoral neck fracture: a one-year follow-up2008Ingår i: Osteoporosis International, ISSN 0937-941X, E-ISSN 1433-2965, Vol. 19, nr 6, s. 801-809Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A randomized, controlled fall-prevention study including 199 patients operated on for femoral neck fracture reduced inpatient falls and injuries. No statistically significant effects of the intervention program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone old people. Introduction This study evaluates whether a postoperative multidisciplinary, multifactorial fall-prevention program performed by a geriatric team that reduced inpatient falls and injuries had any continuing effect after discharge. The intervention consisted of staff education, systematic assessment and treatment of fall risk factors and vitamin D and calcium supplementation. Methods The randomized, controlled trial with a one-year follow-up at Umea University Hospital, Sweden, included 199 patients operated on for femoral neck fracture, aged >= 70 years. Results After one year 44 participants had fallen 138 times in the intervention group compared with 55 participants and 191 falls in the control group. The crude postoperative fall incidence was 4.16/1,000 days in the intervention group vs. 6.43/1,000 days in the control group. The incidence rate ratio was 0.64 (95% CI: 0.40-1.02, p = 0.063). Seven new fractures occurred in the intervention group and 11 in the control group. Conclusion A team applying comprehensive geriatric assessment and rehabilitation, including prevention and treatment of fall-risk factors, reduced inpatient falls and injuries, but no statistically significant effects of the program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone elderly.

    Attention in Older Adults: A Normative Study of the Integrated Visual and Auditory Continuous Performance Test for Persons Aged 70 Years2015Ingår i: Clinical Neuropsychologist (Neuropsychology, Development and Cognition: Section D), ISSN 1385-4046, E-ISSN 1744-4144, Vol. 29, nr 5, s. 595-610Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: Our objective was to present normative data from 70-year-olds on the Integrated Visual and Auditory Continuous Performance Test (IVA), a computerized measure of attention and response control. Method: 640 participants (330 men and 310 women), all aged 70years, completed the IVA, as well as the Mini-Mental State Examination and the Geriatric Depression Scale. Results: Data were stratified by education and gender. Education differences were found in 11 of 22 IVA scales. Minor gender differences were found in six scales for the high-education group, and two scales for the low-education group. Comparisons of healthy participants and participants with stroke, myocardial infarction, or diabetes showed only minor differences. Correlations among IVA scales were strong (all r > .34, p < .001), and those with the widely used Mini-Mental State Examination were weaker (all r < .21, p < .05). Skewed distributions of normative data from primary IVA scales measuring response inhibition (Prudence) and inattention (Vigilance) represent a weakness of this test. Conclusions: This study provides IVA norms for 70-year-olds stratified by education and gender, increasing the usability of this instrument when testing persons near this age. The data presented here show some major differences from original IVA norms, and explanations for these differences are discussed. Explanations include the broad age-range used in the original IVA norms (66-99years of age) and the passage of 15years since the original norms were collected.

    Fatigue after traumatic brain injury is linked to altered striato-thalamic-cortical functioning2017Ingår i: Brain Injury, ISSN 0269-9052, E-ISSN 1362-301X, Vol. 31, nr 6-7, s. 755-755Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Mental fatigue is a common symptom in the chronic phase of traumatic brain injury. Despite its high prevalence, no treatmentis available for this disabling symptom, and the mechanisms underlying fatigue are poorly understood. Some studies have suggested that fatigue in traumatic brain injury and other neurological disorders might reflect dysfunction within striato-thalamic-cortical loops. In the present study, we investigated whether functional magnetic resonance imaging(fMRI) can be used to detect chronic fatigue after traumatic brain injury (TBI), with emphasis on the striato-thalamic cortical-loops. We included patients who had suffered traumatic brain injury (n = 57, age range 20–64 years) and experienced mental fatigue > 1 year post injury (mean = 8.79 years, SD = 7.35), and age- and sex-matched healthycontrols (n = 27, age range 25–65 years). All participants completed self-assessment scales of fatigue and other symptoms, underwent an extensive neuropsychological test battery and performed a fatiguing 27-minute attention task (the modified Symbol Digit Modalities Test) during fMRI. Accuracy did not differ between groups, but reaction times were slower in the traumatic brain injury group (p < 0.001). Patients showed a greater increase in fatigue than controls from before to after task completion (p < 0.001). Patients showed less fMRI blood oxygen level–dependent activity in several a priori hypothesized regions (family-wise error corrected,p < 0.05), including the bilateral caudate, thalamus and anterior insula. Using the left caudate as a region of interest and testing for sensitivity and specificity, we identified 91% of patients and 81% of controls. As expected, controls showed decreased activation over time in regions of interest—the bilateral caudate and anterior thalamus (p < 0.002, uncorrected)—whereas patients showed no corresponding activity decrease. These results suggest that chronic fatigue after TBI is linked to altered striato-thalamic-cortical functioning. The high precision of fMRI for the detection of fatigue is of great clinical interest, given the lack of objective measures for the diagnosis of fatigue.

    Using Functional Magnetic Resonance Imaging to Detect Chronic Fatigue in Patients With Previous Traumatic Brain Injury: changes linked to altered Striato-Thalamic-Cortical Functioning2018Ingår i: The journal of head trauma rehabilitation, ISSN 0885-9701, E-ISSN 1550-509X, Vol. 33, nr 4, s. 266-274Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To investigate whether functional magnetic resonance imaging (fMRI) can be used to detect fatigue after traumatic brain injury (TBI).

    Setting: Neurorehabilitation clinic.

    Participants: Patients with TBI (n = 57) and self-experienced fatigue more than 1 year postinjury, and age- and gender-matched healthy controls (n = 27).

    Main Measures: Self-assessment scales of fatigue, a neuropsychological test battery, and fMRI scanning during performance of a fatiguing 27-minute attention task.

    Results: During testing within the fMRI scanner, patients showed a higher increase in self-reported fatigue than controls from before to after completing the task (P < .001).The patients also showed lower activity in several regions, including bilateral caudate, thalamus, and anterior insula (all P < .05). Furthermore, the patients failed to display decreased activation over time in regions of interest: the bilateral caudate and anterior thalamus (all P < .01). Left caudate activity correctly identified 91% of patients and 81% of controls, resulting in a positive predictive value of 91%.

    Conclusion: The results suggest that chronic fatigue after TBI is associated with altered striato-thalamic-cortical functioning. It would be of interest to study whether fMRI can be used to support the diagnosis of chronic fatigue in future studies.

    Pharmaco-fMRI in Patients With Traumatic Brain Injury: A Randomized Controlled Trial With the Monoaminergic Stabilizer (-)-OSU61622019Ingår i: The journal of head trauma rehabilitation, ISSN 0885-9701, E-ISSN 1550-509X, Vol. 34, nr 3, s. 189-198Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To examine the effects of monoaminergic stabilizer (-)-OSU6162 on brain activity, as measured by blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI), in patients in the chronic phase of traumatic brain injury suffering from fatigue.

    SETTING: Neurorehabilitation clinic.

    PARTICIPANTS: Patients with traumatic brain injury received either placebo (n = 24) or active treatment (n = 28). Healthy controls (n = 27) went through fMRI examination at one point and were used in sensitivity analysis on normalization of BOLD response.

    DESIGN: Randomized, double-blinded, placebo-controlled design.

    MAIN MEASURES: Effects on BOLD signal changes from before to after treatment during performance of a fatiguing attention task.

    RESULTS: The fMRI results revealed treatment effects within the right occipitotemporal cortex and the right orbitofrontal cortex. In these regions, the BOLD response was normalized relative to healthy controls at the postintervention fMRI session. No effects were seen in regions in which we previously observed activity differences between patients and healthy controls while performing this fMRI task, such as the striatum.

    CONCLUSION: (-)-OSU6162 treatment had influences on functional brain activity, although the normalized regional BOLD response was observed in regions that were not a priori hypothesized to be sensitive to this particular treatment, and was not accompanied by any effects on in-scanner test performance or on fatigue.

    White matter hyperintensities increases with traumatic brain injury severity: associations to neuropsychological performance and fatigue2020Ingår i: Brain Injury, ISSN 0269-9052, E-ISSN 1362-301X, Vol. 34, nr 3, s. 415-420Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To examine the prevalence of white matter hyperintensities (WMHs) in patients with traumatic brain injury (TBI) as compared to healthy controls, and to investigate whether there is an association between WMH lesion burden and performance on neuropsychological tests in patients with TBI.

    Methods: A total of 59 patients with TBI and 27 age- and gender-matched healthy controls underwent thorough neuropsychological testing and magnetic resonance imaging. The quantification of WMH lesions was performed using the fully automated Lesion Segmentation Tool.

    Results: WMH lesions were more common in patients with TBI than in healthy controls (p = .032), and increased with higher TBI severity (p = .025). Linear regressions showed that WMH lesions in patients with TBI were not related to performance on any neuropsychological tests (p > .05 for all). However, a negative relationship between number of WMH lesions in patients with TBI and self-assessed fatigue was found (r = - 0.33, p = .026).

    Conclusion: WMH lesions are more common in patients with TBI than in healthy controls, and WMH lesions burden increases with TBI severity. These lesions could not explain decreased cognitive functioning in patients with TBI but did relate to decreased self-assessment of fatigue after TBI.

    Conclusion: WMH lesions are more common in patients with TBI than in healthy controls, and WMH lesions burden increases with TBI severity. However, these lesions do not seem to explain the decreased cognitive functioning or the increased fatigue in patients with TBI.

    The effects of (-)-OSU6162 on chronic fatigue in patients with traumatic brain injury: a randomized controlled trial2017Ingår i: The journal of head trauma rehabilitation, ISSN 0885-9701, E-ISSN 1550-509X, Vol. 32, nr 2, s. E46-E54Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To examine the effects of the monoaminergic stabilizer (-)-OSU6162 on mental fatigue in patients with traumatic brain injury.

    SETTING: Single-center Neurorehabilitation Clinic.

    DESIGN: Randomized, double-blind, placebo-controlled trial.

    PARTICIPANTS: Sixty-four subjects with traumatic brain injury were randomized to treatment (n = 33) and placebo (n = 31).

    MAIN MEASURES: The effects of (-)-OSU6162 at a dose of 15 mg twice a day were evaluated using self-assessment scales and neuropsychological tests measuring mental fatigue.

    RESULTS: No difference between groups was observed on any scale at baseline. At follow-up, both groups showed significant improvement on the Fatigue Severity Scale and the Mental Fatigue Scale (both Ps < .01). Similarly, the performance of both groups increased significantly on many neuropsychological tests. However, no significant between-group difference in changes on these scales was observed before or after adjustment for confounders except for one neuropsychological test favoring the control group. Sensitivity analyses showed significantly greater changes in levels of prolactin and folic acid and heart rate (all Ps < .05) in the treatment group. The mean plasma concentration after 4 weeks of treatment was 0.14 (range, 0.01-0.32) μM, which was lower than expected.

    INTERPRETATION: Treatment with (-)-OSU6162 had no significant effect on mental fatigue in patients with traumatic brain injury compared with placebo.

    Benefits and harms of Bisphosphonates: an observational study2022Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: Bisphosphonates are first-line treatment for osteoporosis, but osteoporosis is considered an undertreated disease. The general aim of this dissertation was to further study the benefits and harms of bisphosphonates. There were four specific research questions: (1) Do bisphosphonates reduce the risk of new fractures in older adults who have a history of fracture? (2) Do bisphosphonates reduce the risk of fracture in people taking glucocorticoids? (3) Does confounding explain why bisphosphonates are associated with lower mortality in observational studies? (4) Do bisphosphonates increase the risk of non-jaw osteonecrosis?

    Methods: To answer these questions, we used Swedish register data on deaths, diagnoses, and prescription medications to conduct four matched cohort studies of bisphosphonate users and nonusers. The cohorts were selected from patients registered in the Hip Fracture Register and from all residents of Sweden who were aged 50 years or older on December 31, 2005.

    Results: (1) Bisphosphonate users had an initially increased risk of sustaining new fractures, which appeared to be due to an underlying high risk of fracture. This increased risk diminished over time, which is consistent with a gradual treatment effect, but it is also consistent with a bias known as depletion of susceptibles. (2) Bisphosphonate users had a lower risk of fracture during glucocorticoid therapy. (3) Bisphosphonate users had a lower mortality rate from day 2 of treatment. Although such an early treatment effect cannot be ruled out, this finding is consistent with confounding. (4) Bisphosphonate users had an increased risk of developing non-jaw osteonecrosis. 

    Conclusion: Most of the results were difficult to interpret as true benefits or harms of bisphosphonates because alternative explanations, arising from bias or confounding, were likely. The exception was the results of Study 2, where alternative explanations are more difficult to find. Therefore, Study 2 suggests that bisphosphonates reduce the risk of fractures in glucocorticoid-treated patients. Further research is needed to clarify the potential effects of bisphosphonates on mortality, non-jaw osteonecrosis, and new fractures after a previous fracture.

    Risk factors for COVID-19 diagnosis, hospitalization, and subsequent all-cause mortality in Sweden: a nationwide study2021Ingår i: European Journal of Epidemiology, ISSN 0393-2990, E-ISSN 1573-7284, Vol. 36, nr 3, s. 287-298Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We conducted a nationwide, registry-based study to investigate the importance of 34 potential risk factors for coronavirus disease 2019 (COVID-19) diagnosis, hospitalization (with or without intensive care unit [ICU] admission), and subsequent all-cause mortality. The study population comprised all COVID-19 cases confirmed in Sweden by mid-September 2020 (68,575 non-hospitalized, 2494 ICU hospitalized, and 13,589 non-ICU hospitalized) and 434,081 randomly sampled general-population controls. Older age was the strongest risk factor for hospitalization, although the odds of ICU hospitalization decreased after 60–69 years and, after controlling for other risk factors, the odds of non-ICU hospitalization showed no trend after 40–49 years. Residence in a long-term care facility was associated with non-ICU hospitalization. Male sex and the presence of at least one investigated comorbidity or prescription medication were associated with both ICU and non-ICU hospitalization. Three comorbidities associated with both ICU and non-ICU hospitalization were asthma, hypertension, and Down syndrome. History of cancer was not associated with COVID-19 hospitalization, but cancer in the past year was associated with non-ICU hospitalization, after controlling for other risk factors. Cardiovascular disease was weakly associated with non-ICU hospitalization for COVID-19, but not with ICU hospitalization, after adjustment for other risk factors. Excess mortality was observed in both hospitalized and non-hospitalized COVID-19 cases. These results confirm that severe COVID-19 is related to age, sex, and comorbidity in general. The study provides new evidence that hypertension, asthma, Down syndrome, and residence in a long-term care facility are associated with severe COVID-19.
