    The idiopathic environmental intolerance symptom inventory: development, evaluation, and application2009Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 51, nr 7, s. 838-847Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To develop, evaluate, and apply a questionnaire-based instrument for investigation of specific symptoms in idiopathic environmental intolerance (IEI), called the Idiopathic Environmental Intolerance Symptom Inventory (IEISI).

    Methods: Participants with IEI to chemicals responded to 82 candidate symptoms and to three subscales of the Quick Environmental Exposure and Sensitivity Inventory (QEESI) at a test (n = 207) and retest (n = 193) occasion.

    Results: The 27 most commonly reported symptoms were selected and grouped into five symptom categories. Internal consistency, test-retest reliability, and concurrent validity were found to be satisfying. Cluster analysis identified two subgroups of IEI to chemicals.

    Conclusions: The results provide support for the IEISI being a reliable, valid, and fast tool for the study of specific symptom prevalence in IEI and encourage further study of subgroups.

    Pregnancy outcomes after paternal radiofrequency field exposure aboard fast patrol boats2012Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 54, nr 4, s. 431-438Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To investigate adverse reproductive outcomes among male employees in the Royal Norwegian Navy exposed to radiofrequency electromagnetic fields aboard fast patrol boats.

    Methods: Cohort study of Royal Norwegian Navy servicemen linked to the Medical Birth Registry of Norway, including singleton offspring born between 1967 and 2008 (n = 37,920). Exposure during the last 3 months before conception (acute) and exposure more than 3 months before conception (nonacute) were analyzed.

    Results: Perinatal mortality and preeclampsia increased after service aboard fast patrol boats during an acute period and also after increased estimated radiofrequency exposure during an acute period, compared with service aboard other vessels. No associations were found between nonacute exposure and any of the reproductive outcomes.

    Conclusions: Paternal work aboard fast patrol boats during an acute period was associated with perinatal mortality and preeclampsia, but the cause is not clear.

    The Hand-Arm Vibration International Consortium (HAVIC): prospective studies on the relationship between power tool exposure and health effects.2007Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 49, nr 3, s. 289-301Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: The Hand-Arm Vibration International Consortium (HAVIC) is a collaboration of investigators from Europe and North America studying health effects from hand-arm vibration (HAV). Features include prospective design, cross-cohort exposure, and health assessment methods. METHODS: Two new cohorts (dental hygienists and dental hygiene students), two existing cohorts (Finnish forest workers, and Swedish truck cab assemblers), and a previous population (US shipyard workers) are included. Instruments include surveys, quantitative medical tests, physical examination, and work simulation and data logging to assess exposure. New methods were developed for nerve conduction and data logging. RESULTS: Findings on the relationship between nerve conduction and skin temperature in HAV-exposed subjects resulted in a new approach to subject warming. CONCLUSIONS: Integrating established cohorts has advantages over de novo cohort construction. Complex laboratory tests can be successfully adapted for field use.

    Comorbidity of Airway Inflammatory Diseases in Chemical and Building-Related Intolerance2018Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 60, nr 4, s. 295-300Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: This study investigated comorbidity in chemical intolerance (CI) and building- related intolerance (BRI) with (i) chronic sinusitis, chronic obstructive pulmonary disease, allergic and nonallergic asthma and allergic rhinitis, and (ii) airway inflammatory symptoms. Methods: Data from two population-based questionnaire surveys, the Västerbotten and Österbotten Environmental Health Studies, were used. The participants were categorized as CI or BRI and referents, and binary logistic regression analysis was applied. Results: Prevalence rates for the case groups were 7.2% to 40.0% for diseases and 24.3% to 68.9% for symptoms, whereas adjusted odds ratios (ORs) were 3.4 to 26.1 for diseases and 3.3 to 17.0 for symptoms, all being significantly higher than unity. Prevalence rates and ORs were in general higher in BRI than in CI. Conclusion: Inflammatory airway diseases and symptoms are associated with CI and BRI, which encourages further research regarding underlying mechanisms and treatments.

    Worksite Walkthrough Intervention Data-driven Prevention of Workplace Violence on Hospital Units2017Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 59, nr 9, s. 875-884Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aim of this study was to describe the implementation of a data-driven, unit-based walkthrough intervention shown to be effective in reducing the risk of workplace violence in hospitals. Methods: A structured worksite walkthrough was conducted on 21 hospital units. Unit-level workplace violence data were reviewed and a checklist of possible prevention strategies and an Action Plan form guided development of unit-specific intervention. Unit supervisor perceptions of the walkthrough and implemented prevention strategies were reported via questionnaires. Prevention strategies were categorized as environmental, behavioral, or administrative. Results: A majority of units implemented strategies within 12 months' postintervention. Participants found the walkthrough useful, practical, and worthy of continued use. Conclusions: Structured worksite walkthroughs provide a feasible method for workplace violence reduction in hospitals. Core elements are standardized yet flexible, promoting fidelity and transferability of this intervention.

    The risk of lung cancer after cessation of asbestos exposure in construction workers using pleural malignant mesothelioma as a marker of exposure.2014Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 56, nr 12, s. 1297-1301Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To study the risk of lung cancer in heavily asbestos-exposed workers after the exposure to asbestos has ended.

    METHODS: Lung cancer was studied in a cohort of 189,896 Swedish construction workers through a linkage with the Swedish Cancer Registry. Asbestos exposure was estimated by the incidence of malignant mesothelioma in the occupational group.

    RESULTS: There were in total 2835 cases of lung cancer. Workers with heavy exposure to asbestos had an increased risk of lung cancer (relative risks = 1.74; 95% confidence interval, 1.25 to 2.41) before exposure ended and a similar risk to those with low exposure 20 years after the exposure had ceased (relative risks = 0.94; 95% confidence interval, 0.77 to 1.15).

    CONCLUSIONS: Workers with heavy exposure to asbestos have a similar risk of lung cancer as persons with low or no exposure 20 years after the exposure has ended.

    Comorbidity and multimorbidity of asthma and allergy and intolerance to chemicals and certain buildings2017Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 59, nr 1, s. 80-84Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: We tested the hypothesis of high comorbidity between asthma/allergy and chemical intolerance (CI) and between asthma/allergy and building intolerance (BI), and high multimorbidity between asthma/allergy, CI, and BI.

    Methods: Population-based questionnaire data were used from 530 participants with asthma/allergy (allergic asthma, nonallergic asthma, allergic rhinitis, and/or atopic dermatitis), 414 with self-reported and 112 with physician-diagnosed CI, and 165 with self-reported and 47 with physician-diagnosed BI. Separate reference groups were formed for each of the five case groups.

    Results: Adjusted odds ratios varied from 4.6 to 13.1 for comorbidity, and from 6.6 to 46.4 for multimorbidity.

    Conclusion: The large comorbidity and multimorbidity between asthma/allergy, CI, and BI evokes the question as to whether there are similarities in underlying mechanisms between these conditions.

    Respiratory and Ocular Symptoms Among Employees at Swedish Indoor Swimming Pools2016Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 58, nr 12, s. 1190-1195Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: This study investigated trichloramine exposure and prevalence of respiratory and ocular symptoms among Swedish indoor swimming pool workers.

    Methods: Questionnaires were distributed to pool workers and referents. Lung function and fraction of exhaled nitric oxide (FeNO) were measured before and after work. Exposure to trichloramine and trihalomethanes was measured over work shifts.

    Results: The mean personal trichloramine exposure was 36 μg/m3. Significantly more exposed workers reported ocular and nasal symptoms. There were significant differences between groups in FeNO change following work, with exposed showing increased FeNO, which grew when analyses included only nonsmokers.

    Conclusions: The findings indicate that indoor swimming pool environments may have irritating effects on mucous membranes. FeNO data also indicate an inflammatory effect on central airways, but the clinical relevance is unclear. Low trichloramine levels found in this study were not associated with health effects.

    Influence of obesity and physical workload on disability benefits among construction workers followed up for 37 years2017Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 74, nr 9, s. 621-627Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: The objectives of this study are to investigate the relation between obesity and labour force exit via diagnosis-specific disability benefits, and whether physical workload modifies this association.

    METHODS: A longitudinal analysis was performed among 3 28 743 Swedish construction workers in the age of 15-65 years. Body weight and height were measured at a health examination and enriched with register information on disability benefits up to 37 years later. Diagnoses of disability benefits were categorised into cardiovascular diseases (CVDs), musculoskeletal diseases (MSDs), mental disorders and others. A job exposure matrix, based on self-reported lifting of heavy loads and working in bent forward or twisted position, was applied as a measure of physical workload. Cox proportional hazards regression analyses were performed, and the relative excess risk due to interaction (RERI) between obesity and physical workload was calculated.

    RESULTS: Obese construction workers were at increased risk of receiving disability benefits (HR 1.70, 95% CI 1.65 to 2.76), mainly through CVD (HR 2.30) and MSD (HR 1.71). Construction workers with a high physical workload were also more likely to receive a disability benefit (HR 2.28, 95% CI 2.21 to 2.34), particularly via MSD (HR 3.02). Obesity in combination with a higher physical workload increased the risk of disability benefits (RERI 0.28) more than the sum of the risks of obesity and higher physical workload, particularly for MSD (RERI 0.44).

    CONCLUSIONS: Obesity and a high physical workload are risk factors for disability benefit. Furthermore, these factors are synergistic risk factors for labour force exit via disability benefit through MSD. Comprehensive programmes that target health promotion to prevent obesity and ergonomic interventions to reduce physical workload are important to facilitate sustained employment.

    Neurophysiological effects of flickering light in patients with perceived electrical hypersensitivity1997Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 39, nr 1, s. 15-22Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An increasing number of people in Sweden are claiming that they are hypersensitive to electricity, These patients suffer from shin as well as neurological symptoms when they are near computer monitors, fluorescent tubes, or other electrical appliances, Provocation studies with electromagnetic fields emitted from these appliances have, with only one exception, all been negative, indicating that there are other factors in the office environment that can effect the autonomic and/or central nervous system resulting in the symptoms reported, Flickering light is one such factor and was therefore chosen as the exposure parameter in this study, Ten patients complaining of electrical hypersensitivity and the same number of healthy voluntary control subjects were exposed to amplitude-modulated light, The sensitivity of the brain to this type of visual stimulation was tested by means of objective electrophysiological methods such as electroretinography and visual evoked potential, A higher amplitude of brain cortical responses at all frequencies of stimulation was found when comparing patients with the control subjects, whereas no differences in retinal responses were revealed.

    Agreement of Safety Climate: Does it Affect Employees' and Managers' Health and Work Performance?2019Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 61, nr 4, s. E125-E131Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To investigate whether agreement and disagreement between teams and their managers on safety climate relates to their health and work performance. Methods: Questionnaire ratings of 47 managers and 211 employees on safety climate and self-rated health, stress, work ability, and work performance were analyzed using polynomial regression with response surface analyses. Results: Teams' stress was lower when there was agreement between the team and the manager on safety climate, and their work performance was lower when the manager rated safety climate higher than the team did. Managers' health, but not their work performance, was higher for managers who were in agreement with their teams. Conclusions: Agreement between managers and teams on safety climate was related to both employee and manager health outcomes. Disagreement (managers' ratings higher than teams') was negatively related to employee work performance.

    Serum Metabolites in Hand-Arm Vibration Exposed Workers2020Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To investigate whether low molecular organic biomarkers could be identified in blood samples from vibration exposed workers using a metabolomics.

    Methods: The study population consisted of 38 metalworkers. All participants underwent a standardized medical examination. Blood samples were collected before and after work shift and analyzed with GC-TOFMS. Multivariate modeling (orthogonal partial least-squares analysis with discriminant analysis [OPLS-DA]) were used to verify differences in metabolic profiles.

    Results: Twenty-two study participants reported vascular symptoms judged as vibration-related. The metabolic profile from participants with vibration-induced white fingers (VWF) was distinctly separated from participants without VWF, both before and after vibration exposure.

    Conclusion: Metabolites that differed between the groups were identified both before and after exposure. Some of these metabolites might be indicators of health effects from exposure to vibrations. This is the first time that a metabolomic approach has been used in workers exposed to vibrations.

    Exposure to nonpermanent employment and health: analysis of the associations with 12 health indicators2011Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 53, nr 6, s. 653-657Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: To clarify the associations of nonpermanent employment with poor health in longitudinal setting with different health outcomes.

    METHODS: A population cohort (n = 1071) was surveyed at the age of 30 and then again at the age of 42. They were classified according to exposure to nonpermanent employment. The outcomes included indicators of mental and somatic health and health behavior.

    RESULTS: When adjusted for baseline level of the outcome under study, the odds ratio of the heavily exposed was 1.90 (1.25 to 2.88) for nervous symptoms, 1.77 (1.03 to 2.05) for psychological distress, and 1.52 (1.03 to 2.25) for suboptimal mood. Among the lightly exposed, the odds ratio for psychological distress was 1.94 (1.10 to 2.10).

    CONCLUSIONS: Psychological distress is particularly sensitive to exposure to nonpermanent employment. The effects on somatic health or health behavior should be studied only with carefully specified hypotheses.

    Measuring Self-Rated Productivity Factor Structure and Variance Component Analysis of the Health and Work Questionnaire2014Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 56, nr 12, s. 1302-1307Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To test the factor structure and variance components of the productivity subscales of the Health and Work Questionnaire (HWQ). Methods: A total of 272 individuals from one company answered the HWQ scale, including three dimensions (efficiency, quality, and quantity) that the respondent rated from three perspectives: their own, their supervisor's, and their coworkers'. A confirmatory factor analysis was performed, and common and unique variance components evaluated. Results: A common factor explained 81% of the variance (reliability 0.95). All dimensions and rater perspectives contributed with unique variance. The final model provided a perfect fit to the data. Conclusions: Efficiency, quality, and quantity and three rater perspectives are valid parts of the self-rated productivity measurement model, but with a large common factor. Thus, the HWQ can be analyzed either as one factor or by extracting the unique variance for each subdimension.
