    Reactivated herpes simplex infection increases the risk of Alzheimer's disease2015Inngår i: Alzheimer's & Dementia, ISSN 1552-5260, E-ISSN 1552-5279, Vol. 11, nr 6, s. 593-599Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Previous studies have suggested a link between herpes simplex virus (HSV) type 1 and the development of Alzheimer's disease (AD).

    METHODS: The present analysis included 3432 persons (53.9% women, mean age at inclusion 62.7 ± 14.4 years) with a mean follow-up time of 11.3 years. The number of incident AD cases was 245. Serum samples were analyzed for anti-HSV antibodies (immunoglobulin (Ig)G and IgM) by enzyme-linked immunosorbent assays.

    RESULTS: The presence of anti-HSV IgG antibodies was not associated with an increased risk for AD, controlled for age and sex (hazard ratio, HR, 0.993, P = .979). However, the presence of anti-HSV IgM at baseline was associated with an increased risk of developing AD (HR 1.959, P = .012).

    CONCLUSION: Positivity for anti-HSV IgM, a sign of reactivated infection, was found to almost double the risk for AD, whereas the presence of anti-HSV IgG antibodies did not affect the risk.

    Herpes simplex infection and the risk of Alzheimer's disease: a nested case-control study2015Inngår i: Alzheimer's & Dementia, ISSN 1552-5260, E-ISSN 1552-5279, Vol. 11, nr 6, s. 587-592Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Herpes simplex virus (HSV) is thought to play an etiological role in the development of Alzheimer's disease (AD).

    METHODS: Plasma samples from 360 AD cases (75.3% women, mean age 61.2 years) and 360 age- and sex-matched dementia-free controls, taken on average 9.6 years before AD diagnosis, were analyzed for anti-HSV antibodies (immunoglobulin G, IgG, and immunoglobulin M, IgM) by enzyme-linked immunosorbent assays.

    RESULTS: In the complete sample group, the presence of anti-HSV IgG and IgM antibodies did not increase the risk of AD significantly (odds ratio (OR) 1.636, P = .069 and OR 1.368, P = .299, respectively). In cases with 6.6 years or more between plasma sampling and AD diagnosis (n = 270), there was a significant association between presence of anti-HSV IgG antibodies and AD (OR 2.250, P = .019).

    CONCLUSION: Among persons with a follow-up time of 6.6 years or more, HSV infection was significantly associated with AD.

    Changes in sense of coherence in old age: a 5-year follow-up of the Umeå 85+ study2013Inngår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 27, nr 1, s. 13-19Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: This study aims to describe the changes in sense of coherence (SOC) over time and relate these changes to negative life events among very old people. Design: Prospective and longitudinal study. Subjects:  190 old women and men participated, of whom 56 could be included in the 5-year follow-up. Methods: The mean SOC score from the first and second data collection were compared using a paired sample t-test. The relationship between the index of negative life events and the changes on SOC score between the two data collections was investigate using linear regression. Main outcome measures: Antonovsky's SOC scale and an index of negative life events including severe physical and mental diseases, various losses as losses of spouses, cognitive and functional ability. Result:  For the whole group of subjects (n = 56), the SOC scores was higher (70.1 vs. 73.7, p = 0.029) at the second point measure. The most common negative life events at follow-up were loss of independence in activities in daily living and decrease in cognitive function. A significant correlation between the index of negative life events and changes in SOC over 5 years was found (p = 0.025). The more negative life events, the more decrease in SOC. Conclusion: We concluded that there is a risk of decreased SOC and thereby quality of life when negative life events accumulate among very old people. Nursing interventions might play an important role for maintaining and perhaps strengthening SOC among old people exposed to negative life events.

    Comparison of behavioral and psychological symptoms of dementia and psychotropic drug treatments among old people in geriatric care in 2000 and 2007.2011Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 23, nr 10, s. 1616-1622Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Behavioral and psychological symptoms, such as verbal or physical aggression, aberrant motor behaviors, psychotic symptoms, anxiety, depressive symptoms and apathy are common among people with dementia. The aim of the present study was to compare the one-week prevalence of behavioral and psychological symptoms and psychotropic drug treatment among people with cognitive impairment living in institutional care, in two large, comparable samples from 2000 and 2007.

    Methods: A comparison was made between two cross-sectional samples, collected in 2000 and 2007, comprising 4054 participants with cognitive impairment living in geriatric care units in the county of Västerbotten, Sweden. The Multi-Dimensional Dementia Assessment Scale (MDDAS) was used to assess cognitive impairment and behavioral and psychological symptoms. The use of psychotropic drugs was recorded.

    Results: Between 2000 and 2007, 15 out of 39 behavioral or psychological symptoms had become less common and no symptoms had become more common, after controlling for demographic changes. Four out of six behaviors within the cluster of aggressive behaviors had declined in prevalence. Patients prescribed anti-dementia drugs increased from 5.1% to 18.0% and antidepressant drug use increased from 43.2% to 49.1%, while anxiolytic, hypnotic, sedative and antipsychotic drug use remained largely unchanged.

    Conclusion: The prevalence of many behavioral symptoms had declined from 2000 to 2007, and among these changes, the decline in aggressive behaviors probably has the greatest clinical impact.

    Gottfries' Cognitive Scale for Staff Proxy Rating of Cognitive Function Among Nursing Home Residents2019Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908, Vol. 72, nr 4, s. 1251-1260Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: For research purposes, there is a need for tools to assess an individual's level of cognitive function. For survey-based investigations in nursing home contexts, proxy ratings allow the assessment also of individuals with severe cognitive impairment. Objective: The aim of this study was to describe the feasibility and psychometric properties of Gottfries' cognitive scale when used in a nursing home context for proxy rating of cognitive function. Method: The psychometric properties of Gottfries' cognitive scale were investigated in a sample of 8,492 nursing home residents in Vasterbotten County, Sweden, using item response theory and classic scale theory-based approaches. Results: Cognitive function could be scored in 97.1% of the assessed individuals. The scale had a negligible floor effect, it had items with a large spread in difficulties, it appeared linear, and it distributed the assessed individuals equally over the scale. Internal consistency (Cronbach's alpha) was 0.967, and an exploratory factor analysis revealed three factors of the scale - interpreted to represent orientation to time, to place, and to person. Conclusion: Gottfries' cognitive scale is a feasible tool for grading cognitive function among nursing home residents using staff proxy ratings. The scale has excellent psychometric properties with a very high internal consistency, a favorable distribution of item difficulties producing an almost rectangular distribution of scores, and a negligible floor effect. The scale thus can be recommended for use in survey-based investigations in nursing home contexts.

    The use of central nervous system drugs and analgesics among very old people with and without dementia2008Inngår i: Pharmacoepidemiology and Drug Safety, ISSN 1053-8569, E-ISSN 1099-1557, Vol. 17, nr 9, s. 912-918Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Old people in general, and particularly those with dementia, are more sensitive to adverse drug effects than younger people. Despite this, the use of central nervous system (CNS) drugs among old people is common. The aim of the present study was to compare the use of central nervous system drugs and analgesics among people aged 85 years or older, with and without dementia. METHODS: One half of all people aged 85 years old and all those aged 90, 95 and above in Umeå, Sweden and Vaasa and Mustasaari, Finland, were asked to participate in this part of the GERDA/Umeå 85+ study. Both those living in their own homes and those in institutions were included. Trained investigators performed structured interviews and assessments. Medication data were obtained from the participants and medical records. Dementia disorders were diagnosed according to DSM-IV. RESULTS: Dementia was diagnosed in 247/546 participants (45.2%). A higher proportion of the participants with dementia used paracetamol (50.6% compared to 21.4%, p < 0.001), antipsychotics (22.3% and 2.7%, p < 0.001), antidepressants (33.6% and 11.4%, p < 0.001) and anxiolytics (19.0% and 8.0%, p < 0.001). There were no differences in the use of opioid analgesics, anticonvulsants and hypnotics. CONCLUSIONS: The use of CNS drugs and analgesics was common among this population of very old people. Furthermore, the prescription of CNS drugs was more common among people with dementia. The use of antipsychotics in people with dementia should arouse particular concern, because of the high risk of severe adverse events and the limited evidence of positive effects.

    Herpes Simplex Virus, APOE ɛ4, and Cognitive Decline in Old Age: Results from the Betula Cohort Study2019Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908, Vol. 67, nr 1, s. 211-220Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Herpes simplex virus (HSV) has been suggested to play a role in Alzheimer’s disease (AD) development.

    Objective: The aim of the present study was to investigate the early AD-related symptom episodic memory decline in relation to HSV and carriage of allele 4 of the apolipoprotein E gene (APOE ɛ4) in a large population-based cohort with a long follow-up time.

    Methods: The study included 3,413 persons, with longitudinal data available for 1,293 persons with a mean follow-up time of 11.6 years. The associations between HSV carriage, APOE ɛ4 carriage, and episodic memory was investigated at baseline, as well as in longitudinal analyses where individuals with and without HSV antibodies (HSV1/2 non-specific) were matched and episodic memory decline compared.

    Results: Cross-sectional analyses revealed an age-dependent association of HSV carriage with lower episodic memory function, particularly among APOE ɛ4 carriers (p = 0.008). Longitudinal analyses showed an increased risk of episodic memory decline in HSV carriers (≥65 years: p < 0.001, all ages: non-significant), and a significant interaction between HSV and APOE ɛ4 for episodic memory decline (p < 0.001).

    Conclusion: In this large population-based cohort study, both cross-sectional and longitudinal results support an association between HSV carriage and declining episodic memory function, especially among APOE ɛ4 carriers. The results strengthen the hypothesis that HSV is associated with AD development.

    Interaction between Cytomegalovirus and Herpes Simplex Virus Type 1 Associated with the Risk of Alzheimer’s Disease Development2018Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908, Vol. 61, s. 939-945Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Several environmental factors, including infectious agents, have been suggested to cause Alzheimer's disease (AD). Cytomegalovirus (CMV) has been associated with AD in several recent studies.

    OBJECTIVE: To investigate whether carriage of CMV, alone or in combination with Herpes simplex virus (HSV), increased the risk of developing AD.

    METHODS: Plasma samples from 360 AD cases (75.3% women, mean age 61.2 years), taken an average of 9.6 years before AD diagnosis, and 360 age-, sex-, cohort-, and sampling date matched dementia-free controls were analyzed to detect anti-CMV (immunoglobulin [Ig] G and IgM), group-specific anti-HSV (IgG and IgM), and specific anti-HSV1 and HSV2 IgG antibodies by enzyme-linked immunosorbent assays. AD cases and dementia-free controls were compared using conditional logistic regression analyses.

    RESULTS: The presence of anti-CMV IgG antibodies did not increase the risk of AD (odds ratio [OR], 0.857; p = 0.497). Among AD cases, an association between CMV and HSV1 carriage was detected (OR 7.145, p < 0.001); in a conditional logistic regression model, the interaction between CMV and HSV1 was associated with AD development (OR 5.662; p = 0.007).

    CONCLUSION: The present findings do not support a direct relationship between CMV infection and the development of AD; however, an interaction between CMV and HSV1 was found to be associated significantly with AD development. These findings suggest that CMV infection facilitates the development of HSV1-associated AD, possibly via its effects on the immune system.

    Poor staff awareness of analgesic treatment jeopardises adequate pain control in the care of older people2006Inngår i: Age and Ageing, ISSN 0002-0729, E-ISSN 1468-2834, Vol. 35, nr 3, s. 257-261Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: undertreatment of pain is a common problem in geriatric care. The aim of this study was to compare the caring staff 's answers concerning the resident's pain treatment with actual pharmacological pain treatment in a cross-sectional survey of the geriatric care population in the county of Vasterbotten, Sweden. Methods: a cross-sectional study in all geriatric care units in the county of Vasterbotten, Sweden, including 3,724 inhabitants aged 65 years and over. The mean age was 83.3 and the number of cognitively impaired 2,047 (55.0%). Medication data were obtained from prescription records. The member of staff who knew the resident best judged their pain based on observations the preceding week. Results: the reported pain prevalence in the sample was 56.7%. Of those residents reported to suffer from pain, 27.9% received no analgesics as regular medication. In 72.7% of those cases with reported pain and no pharmacological treatment, the staff member who knew the resident best still thought that the resident was receiving treatment for her/his pain. Conclusion: a large proportion of the old people in geriatric care settings suffer from pain, and undertreatment of pain appears to be a significant problem. Even when the resident was not receiving pharmacological treatment for their pain, the assessor, who was expected to know the resident best, still believed in a majority of cases that the resident was receiving treatment. This highlights the need for better communication between the various professional categories involved in geriatric care.

    Relationship between antipsychotic drug use and behavioral and psychological symptoms of dementia in old people with cognitive impairment living in geriatric care.2006Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 18, nr 4, s. 713-726Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) commonly occur among cognitively impaired people in geriatric care. BPSD are often managed with antipsychotic drugs, despite the associated serious health risks. The aim of the present study was to discover factors associated with the use of antipsychotics.

    METHODS: A cross-sectional study in all geriatric care units in the county of Västerbotten, Sweden, which included 2017 residents aged 65 years and over with cognitive impairment (mean age was 83.5 years). Data were collected from prescription records and observations made by care staff of BPSD among residents during the preceding week. A multivariate regression model was constructed to find factors independently associated with antipsychotic drug use.

    RESULTS: Eleven factors were independently associated with the use of antipsychotics. Aggressive, verbally disruptive and wandering behavior, hallucinatory and depressive symptoms, male sex, living in a group dwelling for people with dementia, imposed mental workload, the ability to rise from a chair, activities of daily living (ADL) dependency and lower age all correlated significantly.

    CONCLUSIONS: Antipsychotic drug treatment of old people with cognitive impairment in geriatric care is common, and determined not only by the patient's symptoms but also by factors related more closely to the caregiver and the caring situation. These findings raise important questions about the indications for drug treatment in relation to the patient's quality of life.

    Behavioral and psychological symptoms of dementia in relation to level of cognitive impairment.2008Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 20, nr 4, s. 777-789Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Many people with dementia exhibit some behavioral or psychological symptoms, e.g. aggressive or aberrant motor behavior, depression or hallucinations, at some time during the course of the disorder. The aim of the present study was to describe the probability of the occurrence of these symptoms of dementia in relation to the level of cognitive impairment.

    METHODS: 3404 people with cognitive impairment were selected from two large cross-sectional surveys of those in geriatric care settings, conducted in 1982 and 2000 in the county of Västerbotten, Sweden. Symptoms were assessed using the Multi-Dimensional Dementia Assessment Scale (MDDAS), subsumed with a rotated factor analysis, and investigated in relation to level of cognitive impairment, measured using the Gottfries cognitive scale.

    RESULTS: The passiveness factor had an almost linear correlation to the level of cognitive impairment (r2 = 0.237). Non-linear correlations, with highest prevalences in middle-stage cognitive impairment, were found for aggressive behavior (r2 = 0.057), wandering behavior (r2 = 0.065), restless behavior (r2 = 0.143), verbally disruptive/attention-seeking behavior (r2 = 0.099), regressive/inappropriate behavior (r2 = 0.058), hallucinatory symptoms (r2 = 0.021) and depressive symptoms (r2 = 0.029).

    CONCLUSION: The relations between the behavioral and psychological symptoms of dementia and level of cognitive impairment were non-linear, with higher prevalence rates in the middle stages of dementia, apart from the symptom of passiveness, which increased almost linearly with the severity of cognitive impairment.

    Changes between 1982 and 2000 in the prevalence of behavioral symptoms and psychotropic drug treatment among old people with cognitive impairment in geriatric care.2009Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 21, nr 5, s. 941-948Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: People with a dementia disorder often live in institutional care facilities, particularly when the dementia disorder becomes severe or complicated by various behavioral disturbances. The aim of the present study was to analyze and compare the one-week prevalence of various behavioral symptoms and psychotropic drug treatment among people with cognitive impairment living in institutional care, in two large, comparable samples from 1982 and 2000. METHODS: A comparison was made between two cross-sectional samples, collected in 1982 and 2000 respectively, comprising 3404 participants with cognitive impairment living in geriatric care units in the county of Västerbotten, Sweden. Behavioral symptoms were measured using the Multi-Dimensional Dementia Assessment Scale (MDDAS) and cognition was measured using Gottfries' cognitive scale. RESULTS: Eight out of 25 behavioral symptoms had become less common, and six more common, after controlling for demographic changes. Regressive behavior, resistance to care and passiveness became less common, while certain aberrant motor behaviors showed an increased prevalence. Antidepressant drug use increased from 6.8% to 43.2%, antipsychotic drug use decreased from 38.0% to 26.2% and anxiolytics, hypnotic and sedative drug use increased from 12.7% to 38.5%. CONCLUSION: One-week prevalence of regressive symptoms and resistance to care had decreased and there were signs of a generally increased activity level among old people with cognitive impairment living in institutional geriatric care in 2000 compared to 1982. These changes may be an effect of the extensive changes in pharmacological treatments and in the organization of institutional geriatric care.

    Sex differences in the prevalence of behavioral and psychological symptoms of dementia.2009Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 21, nr 3, s. 469-475Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: When a person has dementia, non-cognitive behaviors and symptoms might constitute a greater problem than the cognitive decline itself. Male or female sex might be a predisposing factor for certain types of behavior disturbances and symptoms. The aim of the present analysis was to explore the correlation between sex and the prevalence of behavioral and psychological symptoms of dementia. METHOD: A total of 3395 people with cognitive impairment (1056 men and 2339 women) were selected from two large cross-sectional surveys of those in geriatric care settings, conducted in 1982 and 2000 in the county of Västerbotten, Sweden. Symptoms were assessed using the Multi-Dimensional Dementia Assessment Scale (MDDAS), and prevalence was compared using multivariate logistic regression. Drug data were obtained from prescription records. RESULTS: For 17 out of 39 behaviors and symptoms, the prevalence differed significantly between men and women. Men more often exhibited aggressive behavior and regressive behaviors, and women more often exhibited depressive symptoms. There were no sex differences for passiveness and hallucinations. The prevalence of antipsychotic drug use was higher among men (35.5% compared to 28.9%, p < 0.001) and antidepressant drug use higher among women (30.1% compared to 25.6%, p = 0.006). The prevalence of use of anxiolytics, hypnotics and sedatives did not differ. CONCLUSION: There are some differences in the prevalence of behavioral and psychological symptoms of dementia between men and women. These different symptom profiles might possibly explain some of the differences found in the pharmacological treatment of men and women with a dementia disorder.

    Temporal dynamics of basal ganglia under-recruitment in Parkinson's disease: transient caudate abnormalities during updating of working memory.2009Inngår i: Brain, ISSN 0006-8950, E-ISSN 1460-2156, Vol. 132, nr Pt 2, s. 336-346Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Using hybrid-blocked/event-related fMRI and the 2-back task we aimed to decompose tonic and phasic temporal dynamics of basal ganglia response abnormalities in working memory associated with early untreated Parkinson's disease. In view of the tonic/phasic dopamine hypothesis, which posits a functional division between phasic D(2)-dependent striatal updating processes and tonic D(1)-dependent prefrontal context-maintenance processes, we predicted that newly diagnosed, drug-naïve Parkinson's disease patients, with selective striatal dopamine deprivation, would demonstrate transient rather than sustained activation changes in the basal ganglia during 2-back performance. Task-related activation patterns within discrete basal ganglia structures were directly compared between patients and healthy elderly controls. The obtained results yielded uniquely transient underactivation foci in caudate nuclei, putamen and globus pallidus in Parkinson's disease patients, which indicates suboptimal phasic implementation of striatal D(2)-dependent gating mechanisms during updating. Sustained underactivation was only seen in the anterior putamen, which may reflect initial signs of tonic control impairment. No significant changes were exhibited in prefrontal cortex. The present findings resonate well with the tonic/phasic dopamine account and suggest that basal ganglia under-recruitment associated with executive dysfunction in early Parkinson's disease might predominantly stem from deficiencies in phasic executive components subserved by striatum.

    Dementia, depression and delirium in the very old: prevalences and associated factors2013Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Emotional suffering in old age is largely caused by a variety of psychiatric disorders which are often, however, undertreated and underrecognized. This leads to reduced quality of life and functional status and increased morbidity and mortality. Dementia, delirium and depression are common disorders in the very old, and are similar in several ways. All have multiple causes and are diagnosed by means of symptomatic criteria, are challenging to diagnose and difficult to differentiate from each other in the very old. They often coexist in the same individual, and may have common risk factors.

    The overall aim of this thesis was to add to our knowledge about threats to successful aging, by investigating the prevalences of dementia, depression and delirium, and factors associated with these three disorders. Further aims were to measure change over time in the prevalence of dementia and depression, respectively, and to investigate the risk factors for incident depression. This thesis uses the population-based Umeå85+/GErontological Regional DAtabase (GERDA) material.

    In 2000-2002, every other 85-year-old, all 90-year-olds and all people ≥95 years living in six municipalities in Västerbotten, Sweden were invited to participate, and in 2005-2007 the process was repeated, with the additional inclusion of the corresponding populations of two municipalities in Österbotten, Finland. A third data collection was carried out in 2010-2012. Trained assessors carried out assessments in the form of structured interviews during one or more home visits, recorded current medication and reviewed medical records obtained from general practitioners and hospitals. In 2000-2002 the prevalence of dementia was 17% among 85-year-olds, 24% among 90-year-olds and 46% among those aged ≥95 years. In 2005-2007 dementia prevalence reached 28% among 85-year-olds, 40% among 90-yearolds and 45% among those aged ≥95 years. The prevalence of dementia in the total sample was 27% in 2000-2002 and 37% in 2005-2007 (p=0.001). In 2000-2002 the prevalence of depressive disorders was 24% among 85-yearolds, 34% among 90-year-olds and 31% among those aged ≥95 years. In 2005-2007 the prevalence of depressive disorders was 33% among 85-year-olds, 39% among 90-year-olds and 38% among those aged ≥95 years. The prevalence of depressive disorders in the total sample was 29% in 2000-2002 and 37% in 2005-2007 (p=0.025). Among participants not depressed at baseline, 26% had developed depression after five years. Factors independently associated with new cases of depression at follow-up were hypertension, a history of stroke and a higher score on the 15-item Geriatric Depression Scale at baseline. The thirtyday prevalence of delirium in 2005-2007 was 17% among 85-year-olds, 21% among 90-year-olds and 39% among participants aged ≥95 years. Delirium prevalence among individuals with dementia was higher than among those without dementia (52% vs. 5%, p<.001). Factors independently associated with delirium superimposed on dementia in a multivariate logistic regression model were depression, heart failure, living in an institution and prescribed antipsychotics.

    There was a high prevalence of dementia, depression and delirium in the papers comprising this thesis, and 55% had at least one of the three disorders. The prevalence of dementia and depression also increased between 2000-2002 and 2005-2007, after controlling for age and sex. Dementia and depression were important associated factors for delirium and half of those with dementia were depressed. The increasing age-specific prevalence of depression seems to be associated with the increasing age-specific prevalence of dementia. The papers presented are among the first to report a significantly increasing age-specific prevalence of dementia and depression among very old people. More knowledge about associated factors and risk factors concerning these disorders may be helpful for carers and decision-makers, as well as providing reference values for studies in other regions. Further efforts are needed in both care and research to better prevent, screen for, diagnose and treat dementia, depression and delirium, especially considering the growing number of very old people.

    Increasing prevalence of dementia among very old people2011Inngår i: Age and Ageing, ISSN 0002-0729, E-ISSN 1468-2834, Vol. 40, nr 2, s. 243-249Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: it is unknown whether the age-specific prevalence of dementia among the very old changes over time.

    METHODS: this study compares the prevalence of dementia in two population-based cross-sectional samples of very old people in northern Sweden in 2000-02 and in 2005-07. In total, 430 individuals aged 85 and older (mean age 89.5 years, 71.4% women) were evaluated for dementia in the first cross-section and 465 individuals (mean age 90.2 years, 70.9% women) in the second. Trained assessors performed assessments and interviews during home visits and collected information from carers, relatives and medical records. Dementia was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria.

    RESULTS: the prevalence of dementia in the total sample was 26.5% in 2000-02 and 37.2% in 2005-07 (P = 0.001). There was also an increase in the prescription of different antihypertensive agents, antilipemic agents and choline esterase inhibitors, and more people had had heart surgery in the later sample.

    CONCLUSIONS: in this sample of very old people, an increase in the age-specific prevalence of dementia was detected over 5 years. Possible reasons for this may be extended survival among individuals with risk factors for dementia and among individuals with established dementia.

    Thirty-day prevalence of delirium among very old people: a population-based study of very old people living at home and in institutions2013Inngår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 57, nr 3, s. 298-304Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Delirium has mainly been studied in various patient samples and in people living in institutions. The present study investigates the 30-day prevalence of delirium in a population-based sample of very old people in northern Sweden and Finland. Seven hundred and eight persons aged 85 years and older from the GErontological Regional DAtabase (GERDA) were assessed. Information was also collected from relatives, carers and medical records. Assessments performed were among others the Organic Brain Syndrome (OBS) scale, the Mini Mental State Examination (MMSE), and the Geriatric Depression Scale-15 (GDS-15). Delirium, depression and dementia diagnoses were based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. The prevalence of delirium was 17% among 85 year-olds, 21% among 90 year-olds and 39% among participants aged 95 years and older (p < 0.001). Delirium prevalence among individuals without dementia was lower than among those with dementia (5% vs. 52%, p < 0.001). Factors independently associated with delirium superimposed on dementia in a multivariate logistic regression model were depression (Odds Ratio (OR) = 2.0, 95% Confidence Interval (CI) = 1.2–3.3), heart failure (OR = 2.1, 95% CI = 1.2–3.7), institutional living (OR 4.4, 95% CI = 2.4–8.2) and prescribed antipsychotics (OR = 3.0, 95% CI = 1.5–6.0).

    Delirium is highly prevalent among very old people with dementia. Depression, heart failure, institutional living and prescribed antipsychotic medication seem to be associated with delirium.

    Risk factors for depressive disorders in very old age: a population-based cohort study with a five-year follow-up2014Inngår i: Social Psychiatry and Psychiatric Epidemiology, ISSN 0933-7954, E-ISSN 1433-9285, Vol. 49, nr 5, s. 831-839Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Depressive disorders are common among the very old, but insufficiently studied. The present study aims to identify risk factors for depressive disorders in very old age.

    The present study is based on the GERDA project, a population-based cohort study of people aged a parts per thousand yen85 years (n = 567), with 5 years between baseline and follow-up. Factors associated with the development of depressive disorders according to DSM-IV criteria at follow-up were analysed by means of a multivariate logistic regression.

    At baseline, depressive disorders were present in 32.3 % of the participants. At follow-up, 69 % of those with baseline depressive disorders had died. Of the 49 survivors, 38 still had depressive disorders. Of the participants without depressive disorders at baseline, 25.5 % had developed depressive disorders at follow-up. Baseline factors independently associated with new cases of depressive disorders after 5 years were hypertension, a history of stroke and 15-item Geriatric Depression Scale score at baseline.

    The present study supports the earlier findings that depressive disorders among the very old are common, chronic and malignant. Mild depressive symptoms as indicated by GDS-15 score and history of stroke or hypertension seem to be important risk factors for incident depressive disorders in very old age.

    Impact of hip fracture on mortality: a cohort study in hip fracture discordant identical twins2014Inngår i: Journal of Bone and Mineral Research, ISSN 0884-0431, E-ISSN 1523-4681, Vol. 29, nr 2, s. 424-431Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Several studies have shown a long-lasting higher mortality after hip fracture but the reasons of the excess risk is not well understood. We aimed to determine whether there exists a higher mortality after hip fracture when controlling for genetic constitution, shared environment, comorbidity and lifestyle by use of a nation-wide cohort study in hip fracture discordant monozygotic twins. All 286 identical Swedish twin pairs discordant for hip fracture (1972-2010) were identified. Comorbidity and lifestyle information was retrieved by registers and questionnaire information. We used intrapair Cox regression to compute multivariable-adjusted hazard ratios (HRs) for death. During follow-up, 143 twins with a hip fracture died (50%) compared to 101 twins (35%) without a hip fracture. Through the first year after hip fracture, the rate of death increased four-fold in women (HR 3.71; 95% confidence interval (CI) 1.32-10.40) and seven-fold in men (HR 6.67; 95% CI 1.47-30.13). The increased rate in women only persisted during the first year after hip fracture (HR after 1 year 0.99; 95% CI 0.66-1.50), whereas the corresponding HR in men was 2.58 (95% CI 1.02-6.62). The higher risk in men after the hip fracture event was successively attenuated during follow-up. After 5 years, the hazard ratio in men with a hip fracture was 1.19 (95% CI 0.29-4.90). On average, the hip fracture contributed to 0.9 years of life lost in women (95% CI 0.06-1.7) and 2.7 years in men (95% CI 1.7-3.7). The potential years of life lost associated with the hip fracture was especially pronounced in older men (>75 years), with an average loss of 47% (95% CI 31-61) of the expected remaining lifetime. We conclude that both women and men display a higher mortality after hip fracture independent of genes, comorbidity and lifestyle.

    Long-term rivastigmine treatment in a routine clinical setting.2009Inngår i: Acta Neurologica Scandinavica, ISSN 0001-6314, E-ISSN 1600-0404, Vol. 119, nr 3, s. 180-185Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: The aim of the study was to observe the effects of long-term rivastigmine treatment in patients with mild to moderate Alzheimer's disease (AD) in a routine clinical setting. METHODS: This was a prospective, open-label, observational, multicentre, non-randomized study. Outcome measures included the Mini Mental State Examination (MMSE), the Clinician's Interview-Based Impression of Change (CIBIC) and the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog). RESULTS: Of 217 patients initiated into rivastigmine treatment, 62% (n = 135) remained on treatment for 24 months. Most patients droped out due to nursing home placement or side effects. Eighty per cent and 67% of completers exhibited a symptomatic attenuation of cognitive decline (< or = 4-point deterioration) as assessed by using the MMSE and ADAS-cog respectively. Forty-four per cent showed an unchanged/improved CIBIC rating. CONCLUSIONS: Over 60% of patients remained on treatment for 2 years in this routine clinical setting. In patients who remained on treatment, rivastigmine appeared to stabilize their condition and prevented or delayed symptomatic decline.

    Blood pressure in advanced age: with focus on epidemiology, cognitive impairment and mortality2010Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The general conception is that blood pressure increases with age, but that diastolic blood pressure (DBP) starts decreasing in the elderly. There are, however, indications that systolic blood pressure (SBP) might also decline in advanced age, but further studies are needed to establish whether this is true. Midlife hypertension is an acknowledged risk factor for mortality and dementia. Some research has, however, suggested more complicated associations between blood pressure and these outcomes in old age, as low blood pressure has been linked to both increased mortality and increased risk of dementia. Research on this subject, especially in very old people (≥85 years of age), is still limited. The purpose of the present thesis was to investigate blood pressure epidemiology in old age and associations between blood pressure and mortality and cognition in very old people.

    Subjects were mainly derived from the Umeå 85+/GERDA (GErontological Regional DAtabase) study, a study on individuals aged 85 years, 90 years or ≥95 years carried out in northern Sweden and Finland in 2000-2007. For analysis of blood pressure change with age, data from this study were combined with data from the U70 study that was carried out in the city of Umeå, Sweden between 1981-1990 and included individuals aged 70-88 years. Investigations were performed during a home visit in the Umeå 85+/GERDA study and at a geriatric centre in the U70 study. SBP and DBP were measured in the supine position in both studies and pulse pressure (PP) was calculated as SBP-DBP.  Main outcome variables were 4-year mortality, Mini-Mental State Examination (MMSE) scores, dementia and blood pressure change with age and over the years. Treatment with antihypertensive drugs was also considered.

    Blood pressure changes with age and time were investigated using 1133 blood pressure measurements from 705 individuals aged ≥70 years performed between 1981 and 2005. DBP continually decreased with increasing age, whereas SBP and PP increased up to age 74.5 and 80.6 years, respectively, to then start decreasing. Mean SBP and DBP also decreased over the years. The prevalence of treatment with antihypertensive drugs increased during the same period and is probably one explanation for the decrease in blood pressure with time. Blood pressure also decreased in longitudinal analyses of those individuals who participated in more than one data collection. Women had higher SBP and PP than men.

    The association between blood pressure and 4-year mortality was investigated in a sample of 348 individuals aged ≥85 years. Results indicated a non-linear association between SBP and mortality, i.e. both lower and higher SBP were associated with increased mortality. The lowest mortality risk was associated with an SBP of 164 mmHg (95% confidence interval 154-184 mmHg). The analyses were adjusted for a number of diseases and health factors and thus suggest a negative effect of low SBP on survival, independent of health status. There was no association between DBP or PP and 4-year mortality.

    The impact of blood pressure on MMSE scores and dementia was investigated both in a cross-section of 575 individuals and longitudinally in two samples including 102 and 205 individuals, respectively, all ≥85 years old. Cross-sectional analysis demonstrated nonlinear associations between SBP and PP and MMSE scores, indicating poorer cognitive function with both low and high blood pressure. The association between DBP and MMSE scores was linear, higher DBP being associated with higher scores. Individuals with dementia had lower blood pressure than those without dementia. Longitudinally, over five years, no association between baseline blood pressure and incident dementia or change in MMSE scores could be demonstrated. Mean blood pressure declined over this time period, and this decline was greater in individuals who developed dementia than in those who remained dementia free. A greater decline in blood pressure was associated with a greater decline in MMSE scores.

    In conclusion, this study has shown a decrease in both SBP and DBP in advanced age and also that low blood pressure is associated with both increased mortality and poor cognitive function in very old people. These associations might not be fully explained by underlying disease or poor health status; the underlying mechanisms are so far mostly speculative. Very high blood pressure might also remain a risk factor for the mentioned outcomes even in very old age, at least in some people. No association between baseline blood pressure and cognitive decline or incident dementia could be demonstrated, but blood pressure decline was associated with cognitive decline and incident dementia. The direction of this association remains to be determined. Blood pressure also decreased over the years from 1981 to 2005, probably partly due to an increasing prevalence of treatment with antihypertensive drugs.

    Longitudinal associations between blood pressure and dementia in the very old2010Inngår i: Dementia and Geriatric Cognitive Disorders, ISSN 1420-8008, E-ISSN 1421-9824, Vol. 30, nr 3, s. 269-276Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND/AIMS: Midlife hypertension is associated with an increased risk for dementia, but the association between blood pressure and dementia in very old age is unclear.

    METHODS: In a population-based cohort study, a total of 102 individuals aged 85, 90 or ≥ 95 years participated in 2 examinations with a 5-year interval. The investigations consisted of a structured interview, blood pressure measurement, rating scales such as the Mini-Mental State Examination (MMSE) and an investigation of medical charts.

    RESULTS: The majority of participants exhibited a decline in blood pressure. Baseline systolic blood pressure (SBP), diastolic blood pressure or pulse pressure (PP) were not associated with incident dementia or with decline in MMSE scores in multiple regression analyses adjusted for age and sex. However, incident dementia cases exhibited a greater decline in SBP (p = 0.02) and PP (p = 0.04), and decline in SBP was associated with a decline in MMSE score (p = 0.008).

    CONCLUSION: In this small longitudinal study on the very old, no association between baseline blood pressure and incident dementia was found, but individuals who developed dementia exhibited a greater blood pressure decline. Low blood pressure could be an effect of dementia in the very old.

    Low blood pressure is associated with cognitive impairment in very old people2010Inngår i: Dementia and Geriatric Cognitive Disorders, ISSN 1420-8008, E-ISSN 1421-9824, Vol. 29, nr 4, s. 335-341Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND/AIMS: Hypertension is an established risk factor for dementia. However, the association between blood pressure and cognition in the very old is not fully determined and important to study considering the ageing population and the morbidity associated with cognitive impairment. METHODS: This cross-sectional study included 575 individuals aged 85, 90 or 95 years and above and living in northern Sweden or Finland. Participants were interviewed and assessed using a structured protocol. Systolic (SBP) and diastolic blood pressures (DBP) were measured and pulse pressure (PP) calculated. Cognitive function was evaluated using the Mini-Mental State Examination (MMSE). Data were also collected from medical charts and caregivers. RESULTS: After adjustment for several demographic variables and diagnoses, SBP was significantly associated with MMSE in a nonlinear fashion; both high and low pressures were associated with poorer results. There was also a linear and positive association between PP and MMSE scores, but no association with DBP was found. Participants with dementia had lower blood pressure. CONCLUSION: After adjustment for a number of health factors, there was an association between low blood pressure and cognitive impairment. The direction of any causal relationship between blood pressure and cognition remains to be determined.

    Blood pressure change and antihypertensive treatment in old and very old people: evidence of age, sex and cohort effects2013Inngår i: Journal of Human Hypertension, ISSN 0950-9240, E-ISSN 1476-5527, Vol. 27, nr 3, s. 197-203Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The epidemiology of blood pressure in very old age has not been thoroughly studied. The objective of this study was to study blood pressure changes throughout old age and changes in blood pressure and antihypertensive drug use from 1981 to 2005. The study includes 1133 blood pressure measurements from two studies carried out in Umea, Sweden. The U70 study (1981-1990) included individuals aged 70-88 and the Umea 85+/GERDA study (2000-2005) covered people aged 85, 90 or >= 95 years. The impact of age, sex and year of investigation on blood pressure was investigated using linear regression. Mean diastolic blood pressure (DBP) decreased by 0.35mmHg (P<0.001) for each year of age. An inverted U-shaped relation was found between age and systolic blood pressure (SBP), with SBP reaching its maximum at 74.5 years. Mean SBP and DBP also decreased over time (SBP by 0.44mmHg per year, P<0.001 and DBP by 0.34mmHg per year, P<0.001). The proportion of participants on antihypertensive drugs increased from 39.0% in 1981 to 69.4% in 2005. In this study of people aged >= 70 years, mean SBP and DBP decreased with higher age and later investigation year. Antihypertensive drug use increased with time, which might partly explain the observed cohort effect.

    Lower systolic blood pressure is associated with greater mortality in people aged 85 and older2008Inngår i: Journal of The American Geriatrics Society, ISSN 0002-8614, E-ISSN 1532-5415, Vol. 56, nr 10, s. 1853-1859Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: To investigate the association between blood pressure and mortality in very old people. DESIGN: Population-based cohort study.

    SETTING: County of Västerbotten, Sweden.

    PARTICIPANTS: Half of all subjects aged 85 and all of those aged 90 and 95 and older (N=348) in one urban and five rural municipalities in the north of Sweden.

    MEASUREMENTS: Among others, supine blood pressure, Mini-Mental State Examination, Barthel Index of activities of daily living, Mini Nutritional Assessment, and body mass index. Information on diagnoses, medications, and 4-year mortality was collected. Associations between blood pressure and mortality were investigated using Cox regression analyses, controlling for a number of diagnoses and health factors.

    RESULTS: Baseline systolic blood pressure (SBP), diastolic blood pressure, and pulse pressure were all inversely associated with mortality within 4 years according to univariate analysis. SBP was the strongest predictor. In Cox regression analyses, low SBP (≤120 mmHg) correlated with greater 4-year all-cause mortality alone and when controlling for health status. This connection persisted after exclusion of deaths within the first year. There was a tendency toward a U-shaped mortality curve for the adjusted model, with SBP of 164.2 mmHg (95% confidence interval=154.1–183.8 mmHg) being associated with the lowest mortality.

    CONCLUSION: Lower SBP seems to be associated with greater mortality in people aged 85 and older, irrespective of health status. There are indications of a U-shaped correlation between SBP and mortality, and the optimal SBP for this age group could be above 140 mmHg.

    Smoking and All-cause Mortality in Older Adults: Results From the CHANCES Consortium2015Inngår i: American Journal of Preventive Medicine, ISSN 0749-3797, E-ISSN 1873-2607, Vol. 49, nr 5, s. e53-e63Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: Smoking is known to be a major cause of death among middle-aged adults, but evidence on its impact and the benefits of smoking cessation among older adults has remained limited. Therefore, we aimed to estimate the influence of smoking and smoking cessation on all-cause mortality in people aged ≥60 years.

    METHODS: Relative mortality and mortality rate advancement periods (RAPs) were estimated by Cox proportional hazards models for the population-based prospective cohort studies from Europe and the U.S. (CHANCES [Consortium on Health and Ageing: Network of Cohorts in Europe and the U.S.]), and subsequently pooled by individual participant meta-analysis. Statistical analyses were performed from June 2013 to March 2014.

    RESULTS: A total of 489,056 participants aged ≥60 years at baseline from 22 population-based cohort studies were included. Overall, 99,298 deaths were recorded. Current smokers had 2-fold and former smokers had 1.3-fold increased mortality compared with never smokers. These increases in mortality translated to RAPs of 6.4 (95% CI=4.8, 7.9) and 2.4 (95% CI=1.5, 3.4) years, respectively. A clear positive dose-response relationship was observed between number of currently smoked cigarettes and mortality. For former smokers, excess mortality and RAPs decreased with time since cessation, with RAPs of 3.9 (95% CI=3.0, 4.7), 2.7 (95% CI=1.8, 3.6), and 0.7 (95% CI=0.2, 1.1) for those who had quit <10, 10 to 19, and ≥20 years ago, respectively.

    CONCLUSIONS: Smoking remains as a strong risk factor for premature mortality in older individuals and cessation remains beneficial even at advanced ages. Efforts to support smoking abstinence at all ages should be a public health priority.

    Morale in very old people: With focus on stroke, depression and survival2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background: Morale is a multidimensional concept, often defined as a future-oriented optimism or pessimism regarding the problems and opportunities associated with ageing. Very old people, older than 80 years, constitute an age group that is expected to increase in Europe from 4.7% of the general population today to 12.0% in the year 2060 in Europe. The overall aim of this thesis was to explore morale among very old people.

    Method: The Umeå 85+/GErontological Regional Database study (GERDA) is a population-based study carried out in parts of northern Sweden and western Finland in which every second 85 year old, every 90 year old and everyone aged 95 years and older were invited to participate. The study started the year 2000 and every five years re-invites previous participants and invites new individuals to participate in the study. The Philadelphia Geriatric Center Morale Scale (PGCMS), which is widely used to measure morale in old people, has been translated into many languages.

    Results: There were 598 individuals who answered the PGCMS in the Umeå 85+/GERDA study. Despite respondents’ advanced age 92.6% (554/598) answered 16 or 17 of the questions. The construct validity of the Swedish version of the PGCMS was tested among the 493 individuals who answered all 17 questions using confirmatory factor analysis and the analysis showed a generally a good fit. Reliability tested with Cronbach’s alpha was 0.74. Reliability was also tested in a convenience sample of 54 individuals (mean age of 84.7±6.7 years) and the IntraClass Correlation coefficient (ICC) was 0.89.

    Almost 20% (91/465) of participants who could answer the PGCMS had had a stroke. Those with stroke had significantly lower PGCMS scores than those without (10.9±3.8 vs 12.1±3.0, p-value 0.008), but there were 38.5% with stroke history who had high morale. A multiple linear regression analysis showed that depression, angina pectoris and impaired hearing were independently associated with low morale among those with a stroke history.

    A logistic regression model showed that each point increase in PGCMS score lowered the risk of depressive disorders five years later (odds ratio 0.779, p<0.001, with each point increase in PGCMS). In a Cox model adjusted for several demographic, health- and function-related confounders, including age and gender, mortality was higher among participants with low morale (RR=1.36, p=0.032) than those with high morale. There was a similar but non-significant pattern towards increased mortality in participants with moderate morale compared to high morale (RR=1.21, p-value=0.136).

    Conclusion: The feasibility and psychometric properties of the Swedish version of the PGCMS seems to be satisfactory among very old people. A large proportion of very old people have had a stroke, which is associated with reduced morale. Depression, angina pectoris and impaired hearing were independently associated with low morale among those with stroke. Among very old people, a higher level of morale seems to be associated with a lower risk of suffering from depressive disorders five years later. High morale is independently associated with increased five-year survival among very old people.

    Psychometric properties and feasibility of the Swedish version of the Philadelphia Geriatric Center Morale Scale2015Inngår i: Quality of Life Research, ISSN 0962-9343, E-ISSN 1573-2649, Vol. 24, nr 11, s. 2795-2805Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: Morale is related to psychological well-being and quality of life in older people. The Philadelphia Geriatric Center Morale Scale (PGCMS) is widely used to assess morale. The purpose of this study was to evaluate the psychometric properties and feasibility of the Swedish version of the 17-item PGCMS among very old people.

    METHODS: The Umea 85+/GERDA study included Swedish-speaking people aged 85, 90 and 95 years and older, from Sweden and Finland. Participants were interviewed in their own homes using a predefined set of questions. In the main sample, 493 individuals answered all 17 PGCMS items (aged 89.0 +/- 4.3 years). Another 105 answered between 1 and 16 questions (aged 89.6 +/- 4.4 years). A convenience sample was also collected, and 54 individuals answered all 17 PGCMS items twice (aged 84.7 +/- 6.7 years). The same assessor restated the questions within 1 week.

    RESULTS: Cronbach's alpha was 0.74 among those who answered all 17 questions in the main sample. Confirmatory factor analysis was used to test the construct validity of the most widely used version of the PGCMS, with 17 items and three factors, and showed a generally good fit. Among those answering between 1 and 17 PGCMS questions, 92.6 % (554/598) answered 16 or 17. The convenience sample was used for intra-rater test-retesting, and the intraclass correlation coefficient (ICC) was 0.89. The least significant change between two assessments, with 95 % confidence interval, was 3.53 PGCMS points.

    CONCLUSION: The Swedish version of the PGCMS seems to have satisfactory psychometric properties and feasibility among very old people.

    High morale is associated with increased survival in the very old2015Inngår i: Age and Ageing, ISSN 0002-0729, E-ISSN 1468-2834, Vol. 44, nr 4, s. 630-636Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: high morale is defined as future-oriented optimism. Previous research suggests that a high morale independently predicts increased survival among old people, though very old people have not been specifically studied.

    OBJECTIVE: to investigate whether high morale is associated with increased survival among very old people.

    SUBJECTS: the Umeå 85+/GErontological Regional DAtabase-study (GERDA) recruited participants aged 85 years and older in northern Sweden and western Finland during 2000-02 and 2005-07, of whom 646 were included in this study.

    METHODS: demographic, functional- and health-related data were collected in this population-based study through structured interviews and assessments carried out during home visits and from reviews of medical records. The 17-item Philadelphia Geriatric Center Morale Scale (PGCMS) was used to assess morale.

    RESULTS: the 5-year survival rate was 31.9% for participants with low morale, 39.4% for moderate and 55.6% for those with high morale. In an unadjusted Cox model, the relative risk (RR) of mortality was higher among participants with low morale (RR = 1.86, P < 0.001) and moderate morale (RR = 1.59, P < 0.001) compared with participants with high morale. Similar results were found after adjustment for age and gender. In a Cox model adjusted for several demographic, health- and function-related confounders, including age and gender, mortality was higher among participants with low morale (RR = 1.36, P = 0.032) than those with high morale. There was a similar but non-significant pattern towards increased mortality in participants with moderate morale (RR = 1.21, P value = 0.136).

    CONCLUSION: high morale is independently associated with increased survival among very old people.

    Morale in very old people who have had a stroke2014Inngår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 58, nr 3, s. 408-414Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Stroke incidence increases with age and may impact on morale. The aim of this study was to investigate the prevalence of stroke among individuals aged 85 years or older in Northern Sweden and Western Finland and to evaluate factors associated with morale among those who have had a stroke compared with those without a stroke history. This population- based, cross-sectional study included 708 individuals (504 women and 204 men) aged 85 years and older (range 85-107). The study was conducted through structured interviews during home visits and from reviews of medical records, where demographic data and health-related factors were collected. The 17-item Philadelphia Geriatric Center Morale Scale (PGCMS) was used to assess morale. Stroke-prevalence was 22% (156 of 708) in the study population. Ninety-one of 465 participants who could answer PGCMS questions had had a stroke. Those with stroke had significantly lower PGCMS scores than those without (10.9 +/- 3.8 SD vs. 12.1 +/- 3.0 SD, p-value 0.008), but 38.5% had high morale. A multiple linear regression analysis showed that low morale was independently associated with depression, angina pectoris and impaired hearing among those with stroke and another multiple linear regression, among those without a stroke history, showed that low morale was independently associated with depression, pain and poor nutritional status. A large proportion of very old have had stroke which is associated with reduced morale. Low morale among those with stroke was independently associated with depression, angina pectoris and impaired hearing which could be the focus for future intervention studies.

    Higher morale is associated with lower risk of depressive disorders five years later among very old people2017Inngår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 69, s. 61-68Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: The aim of this study was to investigate whether higher morale, i.e. future-oriented optimism, at baseline was associated with lower risk of depressive disorders five years later among very old people.Methods The Umeå85+/GErontological Regional Database, a population-based study with a longitudinal design, recruited participants in Sweden and Finland aged 85, 90 and ≥95 years. The sample in the present study included 647 individuals (89.1±4.4 years (Mean±SD), range 85-103). After five years, 216 were alive and agreed to a follow-up (92.6±3.4 years, range 90-104). The Philadelphia Geriatric Center Morale Scale (PGCMS) was used to assess morale. The depressive disorder diagnosis was determined according to DSM-IV based on medical records and interview data including assessment scales for depressive disorders. A number of sociodemographic, functional and health-related variables were analysed as possible confounders.Results For those with no depressive disorders at baseline, the only baseline variable significantly associated with depressive disorders five years later was the PGCMS score. A logistic regression model showed lower risk of depressive disorders five years later with higher baseline PGCMS scores (odds ratio 0.779 for one point increase in PGCMS, p<0.001). The association remained after adjusting for social isolation (p<0.1 association with depressive disorders five years later).Conclusion Our results indicate that the higher the morale, the lower the risk of depressive disorders five years later among very old people. The PGCMS seems to identify those very old individuals at increased risk of depressive disorders five years later. Preventive measures could befocused on this group.

    Occupational engagement and life satisfaction in the oldest old: the Umeå 85+ study2007Inngår i: OTJR (Thorofare, N.J.), ISSN 1539-4492, E-ISSN 1938-2383, Vol. 27, nr 4, s. 131-139Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study was designed to evaluate whether the level of occupational engagement is relatedto life satisfaction among the oldest-old. The study was performed as part of a cross-sectionalstudy of individuals 85 years and older in northern Sweden. The results revealed significantcorrelations between life satisfaction and engagement in both leisure and activities of daily living,and the effect sizes were interpreted as medium. This study adds some support to earlierfindings that a higher level of task performance is related to a higher level of life satisfaction.The results also give some clinical evidence to support a client-centered approach that includesconsideration of leisure tasks a person is motivated to perform.

    Self-transcendence (ST) among very old people: its associations to social and medical factors and development over five years2015Inngår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 61, nr 2, s. 247-253Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIMS AND OBJECTIVES: The aims of this study were to describe the associations between ST and psychological and physical wellbeing among oldest old people and to test the influence of negative life events on ST, and the predictive value of the self-transcendence scale (STS) for mortality.

    BACKGROUND: ST has been identified as a valuable resource for transcending psychological and physical suffering and has been related to psychological wellbeing and higher quality of life.

    DESIGN: The study design was correlational, prospective, and longitudinal.

    SETTINGS: The participants were recruited from a medium-sized town and from an adjacent rural area in northern Sweden.

    METHOD: The sample consisted of 190 participants (123 women and 67 men) who completed the STS. At a 5-year follow-up, 55 people (29.5%) were alive and able to complete the assessments again.

    RESULTS: ST was positively associated with psychological wellbeing, self-rated health, having someone to talk with and being able to go outdoors independently. Diagnoses of depression, dementia disease, and osteoporosis were associated with lower STS scores as were living in a residential care facility, and feeling lonely. There was a significant relationship between the index of negative life events and ST between baseline and follow-up. More negative life events were associated with a larger decline in STS scores over five years.

    CONCLUSION: ST is an important source for wellbeing among the oldest old, and the accumulation of negative life events might threaten the ability to transcend setbacks.

    Intrinsic and Extrinsic Religious Orientation Among the Very Old2012Inngår i: Journal of Religion, Spirituality & Aging, ISSN 1552-8030, Vol. 24, nr 4, s. 314-324Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to test a shortened version of the Swedish Religious Orientation Scale's (SROS) appropriateness, feasibility, and ability to distinguish between intrinsic and extrinsic religious orientation among very old people. The participants (n = 43) were Lutheran believers aged ≥85 years. They scored high on both the intrinsic and extrinsic sub-scales and a cluster analysis revealed three clusters of items, one measuring intrinsic religious orientation and two measuring extrinsic religious orientation. The shortened version of the SROS appears appropriate for distinguishing between intrinsic and extrinsic religious orientation among very old people.

    Changes in step-width during dual-task walking predicts falls2010Inngår i: Gait & Posture, ISSN 0966-6362, E-ISSN 1879-2219, Vol. 32, nr 1, s. 92-97Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim was to evaluate whether gait pattern changes between single- and dual-task conditions were associated with risk of falling in older people. Dual-task cost (DTC) of 230 community living, physically independent people, 75 years or older, was determined with an electronic walkway. Participants were followed up each month for 1 year to record falls. Mean and variability measures of gait characteristics for 5 dual-task conditions were compared to single-task walking for each participant. Almost half (48%) of the participants fell at least once during follow-up. Risk of falling increased in individuals where DTC for performing a subtraction task demonstrated change in mean step-width compared to single-task walking. Risk of falling decreased in individuals where DTC for carrying a cup and saucer demonstrated change compared to single-task walking in mean step-width, mean step-time, and step-length variability. Degree of change in gait characteristics related to a change in risk of falling differed between measures. Prognostic guidance for fall risk was found for the above DTCs in mean step-width with a negative likelihood ratio of 0.5 and a positive likelihood ratio of 2.3, respectively. Findings suggest that changes in step-width, step-time, and step-length with dual tasking may be related to future risk of falling. Depending on the nature of the second task, DTC may indicate either an increased risk of falling, or a protective strategy to avoid falling.

    Bone mass and physical activity2004Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Abstract

    Weak and osteoporotic bones in old age are an increasing cause of mortality and painful physical impairment of the elderly, especially in the western world. Bone mineral accrual during childhood and adolescence is thought to play a vital role in preventing osteoporosis. Identifying and optimizing the factors influencing peak bone mass is thus important for the prevention of osteoporosis and related fractures.

    A main aim of this thesis was to investigate the potential effects of various types of weight-bearing physical activity on bone accretion in young males just out of puberty. The results from our subgroups of athletes consisting of badminton, ice hockey, and soccer players suggest that weight-bearing physical activity gives rise to regional specific bone response that is determined by the degree of impact of the activity in areas subject to mechanical loading (papers I–IV). In summary, the bone is sensitive to loading after puberty in males, and important bone mass gains can be achieved by proper amount and type of exercise.

    Another aim of this thesis was to studythe effect of detraining on weight-bearing and non-weight-bearing bone in a cohort of adolescent males who participated in ice hockey and soccer training. Our results indicate that exercise-induced bone mineral density benefits decline, predominantly in weight-bearing bones, after retirement from an active sports career (papers II–IV). High bone density stemming from physical loading might be at least partly preserved even by reduced physical activity at nonweight-bearing sites after about three years of reduced activity (III, IV).

    A final aim was to follow prospectively the development of BMD during years of reduced activity in former male athletes, and evaluate whether exercise during adolescence could be associated with fewer fractures in old age. We found fewer fragility fractures in a cohort of 400 former athletes compared to in 800 age-matched controls. Thus, high bone density stemming from previous weight-bearing physical activity may reduce the risk of sustaining fragility fractures in the elderly.

    Key words: physical activity, peak bone mineral density, males.

    Cognitive function and other risk factors for mild traumatic brain injury in young men: nationwide cohort study2013Inngår i: BMJ. British Medical Journal, E-ISSN 1756-1833, Vol. 346, s. f723-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective To investigate cognitive function and other risk factors for mild traumatic brain injury in young men.

    Design Nationwide prospective cohort study.

    Setting Sweden.

    Participants 305 885 men conscripted for military service from 1989 to 1994.

    Main outcome measure mild traumatic brain injuries in relation to cognitive function and other potential risk factors assessed at conscription and follow-up.

    Results Men with one mild traumatic brain injury within two years before (n=1988) or after cognitive testing (n=2214) had about 5.5% lower overall cognitive function scores than did men with no mild traumatic brain injury during follow up (P<0.001 for both). Moreover, men with at least two mild traumatic brain injuries after cognitive testing (n=795) had 15% lower overall cognitive function scores compared with those with no such injury (P<0.001). Independent strong risk factors (P<1x10(-10)) for at least one mild traumatic brain injury after cognitive testing (n=12 494 events) included low overall cognitive function, a previous mild traumatic brain injury, hospital admission for intoxications, and low education and socioeconomic status. In a sub-cohort of twin pairs in which one twin had a mild traumatic brain injury before cognitive testing (n=63), both twins had lower logical performance and technical performance compared with men in the total cohort with no mild traumatic brain injury (P<0.05 for all).

    Conclusion Low cognitive function, intoxications, and factors related to low socioeconomic status were strong independent risk factors for mild traumatic brain injuries in men. The low cognitive function in twin pairs discordant for mild traumatic brain injury suggests a genetic component to the low cognitive function associated with such injuries. The study included only men, so inferences to women should be made with caution.

    The effect of a role-playing exercise on clerkshipstudents’ views of death notification: the Swedish experience2011Inngår i: International Journal of Medical Education, ISSN 2042-6372, Vol. 2, s. 24-29Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives The purpose of this study was to examine clerkship students' perspective towards delivering death notifications. An additional purpose of the study was to identify the learning needs of students following a role play exercise in delivering death notifications.

    Methods Participants in this study were fourth-year medical students (N=86) ranging in age from 22-43 years with a mean age of 27.1 years. There were 28 women and 58 men. Questionnaires, consisting of open-ended questions and a visual analogue scale (VAS), were administered before and after the "Marathon Death" role play exercise.

    Results Six categories emerged from the analysis of the questionnaire: communication, emotions, self-development, exercise-related, learning opportunities and tools and strategies. Results from the visual analogue scale showed that the majority of students (60%) needed to practice how to deliver difficult messages in death notifications. After taking part in the role-playing activity with video playback, where the students had an opportunity to view, discuss and reenact scenarios, seventy-six out of 78 (97.4%) stated that they had received training in communication skills. The responding students rated the exercise as highly relevant, scoring it a mean of 91 on a VAS scale of 0 to 100 mm.

    Conclusions Students are not competent in the communication skills required for delivering death notifications. A majority of students expressed a need for training in communication skills. The "Marathon Death" role play exercise provides initial training and emotional support for delivering a death notification. However, further empirical studies are required about the effect of the exercise on delivering the notification of death.

    Interleukin-6 promoter polymorphism is associated with bone quality assessed by calcaneus ultrasound and previous fractures in a cohort of 75-year-old women2004Inngår i: Osteoporosis International, ISSN 0937-941X, E-ISSN 1433-2965, ISSN 0937-941X, Vol. 15, nr 10, s. 820-826Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Interleukin 6 (IL-6) is a multifunctional cytokine and a potent stimulator of bone resorption and has been implicated in the pathogenesis of osteoporosis in postmenopausal women. The aim of this study was to investigate if a functional IL-6 promoter polymorphism (-174) was related to bone mass and fractures in a cohort consisting of 964 postmenopausal Caucasian women aged 75 years. Bone mineral density (BMD; g/cm2) of the femoral neck, lumbar spine and total body was measured using dual energy X-ray absorptiometry (DXA). Quantitative ultrasound (QUS) was also measured in the calcaneus and quantified as speed of sound (SOS; m/s), broadband ultrasound attenuation (BUA; dB/MHz), and stiffness index (SI). IL-6 genotypes was determined by restriction fragment length polymorphism (RFLP) using the restriction enzyme NlaIII. The frequencies of the different IL-6 genotypes were 27.5% (GG), 47.9% (GC), 24.6% (CC). The IL-6 polymorphism (presence of G) was independently related to a lower stiffness (beta=-0.07; P=0.03) and BUA (beta=-0.08; P=0.02), but not to BMD at any site measured by DXA. In the cohort, 420 subjects (44%) reported at least one fracture during their lifetime, and 349 (36%) reported at least one fracture after the age of 50. Using binary logistic regression, the IL-6 polymorphism (presence of G) was significantly related to an increased risk of a previous fracture during life (odds ratio 1.46, 95% CI 1.08-1.97) and to an increased risk of a fracture occurring after 50 years of age (odds ratio 1.37, 95% CI 1.004-1.88). The risk was further increased for fractures grouped as osteoporotic fractures (odds ratio 1.67, 95% CI 1.14-2.45), including forearm fractures (odds ratio 1.59, 95% CI 1.05-2.40). In conclusion, presence of G allele in the IL-6 promoter polymorphism at position -174 is independently related to previous fractures in postmenopausal women. This association may be related primarily to an altered bone quality identified by QUS and not a lower bone mass. This is also the first demonstration of association of IL-6 gene polymorphism to calcaneal QUS.

    The Higher Prevalence of Type 2 Diabetes in Men Than in Women is Associated with Differences in Visceral Fat Mass2016Inngår i: Journal of Clinical Endocrinology and Metabolism, ISSN 0021-972X, E-ISSN 1945-7197, Vol. 101, nr 10, s. 3740-3746Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Context: We have previously found that visceral fat is a stronger predictor for cardiovascular risk factors than body mass index (BMI). Objective: To investigate the prevalence of diabetes in elderly men and women in relation to objectively assessed visceral fat volume. Design and settings: The cohort consisted of a population-based sample of 705 men and 688 women, all aged 70 years at the time of examination. Main outcome measures: Associations between body fat estimates, plasma glucose level and diabetes prevalence were investigated using multivariable-adjusted statistical models.Results:Theprevalence of type2 diabetes was 14.6% in men and 9.1% inwomen (p0.001). Mean BMI was slightly higher in men than in women (27. 3 vs. 26.6 kg/m2, p 0.01), with a greater difference in mean visceral fat mass (1987 vs. 1087 g, p 0.001). After adjustment for physical activity and smoking, men had about twice the odds of having type 2 diabetes compared with women (OR, 1.95; 95% CI, 1.38–2.76). The inclusion of BMI in this model did not change the risk associated with male sex (OR, 1.93; 95% CI, 1.34–2.77). However, when visceral fat was included as a covariate, male sex was not associated with increased risk of type 2 diabetes (OR, 0.77; 95% CI, 0.51–1.18).Conclusions: The higher prevalence of type 2 diabetes in older men than in older women was associated with larger amount of visceral fat in men. In contrast, differences in BMI was not associated with this difference.

    Postpubertal development of total and abdominal percentage body fat: an 8-year longitudinal study.2008Inngår i: Obesity, ISSN 1930-7381, Vol. 16, nr 10, s. 2342-2347Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of the present study was to describe postpubertal changes in total and abdominal adiposity in young men and the relation to changes in physical activity (PA). The study included 107 white men with a mean age of 17.1 +/- 1.7 years at baseline. Total percentage body fat (%BF) and abdominal percentage body fat (abd%BF) were measured at baseline and after a mean time of 28, 68, and 92 months using dual-energy X-ray absorptiometry (DXA). PA (h/week) was assessed at each visit by questionnaire. Over the study period, significant increases of 7.8 +/- 5.5%BF and 9.0 +/- 5.6 abd%BF were observed. Subjects who were active athletes throughout the study (n = 24), or nonathletes not changing their level of PA during follow-up (n = 27) increased 5.7 +/- 3.2 and 8.1 +/- 6.7%BF, respectively. Athletes who quit organized training during follow-up period (n = 56) increased by 8.7 +/- 4.9%BF. In the total cohort, the average annual gains in BMI, %BF, and abd%BF were 0.4 kg/m(2), 0.9%BF, and 1.1abd%BF (all P < 0.0001), respectively. Adjustment for changes in PA altered the coefficient magnitudes only marginally. Changes in PA were, however, significantly and inversely associated with changes in %BF and abd%BF (P = 0.005 and P = 0.02, respectively), but were not significantly associated with BMI development (P = 0.15). In summary, our results indicate that the natural course of adiposity development in postpubertal men is characterized by adiposity gains. The influence of PA on especially abd%BF may influence the future risk of cardiovascular disease.
