- The aim was to study mortality due to cardiovascular disease as well as total mortality, among female industrial workers, and the association to occupational noise and shift work.Women from cohorts of soft tissue paper mills (N=3013) and pulp and paper mills (N=1483) were merged into one cohort. Job exposure matrices were developed and used for classification of shift work and noise exposure. Every year was classified as shift work excluding nights or shift work including nights. Noise was classified into seven 5dB(A) bins from<75 to≥100dB(A). Mortality from cardiovascular diseases and total mortality during 1956-2013 was calculated as a standardized mortality ratio (SMR) with 95% confidence interval (CI) using the female general population as a reference.Fatal myocardial infarctions (N=144) were increased in the total cohort, SMR 1.20 (95% CI 1.01-1.41) but not total mortality. The SMR for myocardial infarction for women exposed to noise≥90dB(A) for>10years was 1.41 (95% CI 1.02-1.89) and for those exposed to night shifts>10years, 1.33 (95% CI 0.91-1.89). Shift workers without nights≤65years, with noise exposure≥90dB(A), had SMR 2.41 (95% CI 1.20-4.31) from myocardial infarction. There was no increased mortality from cerebrovascular disease.Female paper mill workers had an increased mortality from acute myocardial infarction, especially before retirement age, when exposed to noise≥90dB(A) and with long-time employment. Exposure to shift work and noise usually occurred concurrently.

- Purpose The aim was to examine potential associations between psychosocial job exposures, evaluated with the Job Demand-Control-model, and presence of coronary artery calcium. Methods We performed a cross-sectional study using the Swedish CArdioPulmonary bioImage Study,(SCAPIS)pilot study. Coronary artery calcium was assessed through computed tomography of the coronary arteries and with coronary artery scoring, CACS. Main outcome was CACS >= 100 compared to CACS 0. Job demand and control was analysed according to the standard categorization of the two variables into: high strain, active, passive and low strain (reference). Associations between these variables and CACS were calculated with prevalence ratios (PR) using Cox regression with robust variance, 95% confidence intervals (CI) and adjusted for age, smoking, education, socioeconomic area and metabolic syndrome. Results In total 777 participants were used in our analyses, for which 20% of the men and 5% of the women had CACS >= 100, respectively. The PR of having CACS >= 100 was non-significantly elevated for men in high strain jobs 1.54 (95% CI 0.88-2.69) and in active jobs 1.67 (95% CI 0.92-3.06), adjusted for covariates. For women there was no association between exposure to high strain and having CACS >= 100 PR 1.02 (95% CI 0.24-4.31). Among women reporting passive job, the PR was non-significantly elevated, 2.40 (95% CI 0.83-6.92), adjusted for covariates. Conclusion The statistical power of the study was limited, but our results suggests the possibility that exposure to a high strain or an active job situation may increase the risk of CACS in men, while in women, it may rather be exposure to passive job.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Background: Numerous studies have reported an association between stressing work conditions and cardiovascular disease. However, more evidence is needed, and the etiological mechanisms are unknown. Elevated resting heart rate has emerged as a possible risk factor for cardiovascular disease, but little is known about the relation to work-related stress. This study therefore investigated the association between job strain, job control, and job demands and resting heart rate. Methods: We conducted a cross-sectional survey of randomly selected men and women in Västra Götalandsregionen, Sweden (West county of Sweden) ( n = 1552). Information about job strain, job demands, job control, heart rate and covariates was collected during the period 2001 – 2004 as part of the INTERGENE/ADONIX research project. Six different linear regression models were used with adjustments for gender, age, BMI, smoking, education, and physical activity in the fully adjusted model. Job strain was operationalized as the log-transformed ratio of job demands over job control in the statistical analyses. Results: No associations were seen between resting heart rate and job demands. Job strain was associated with elevated resting heart rate in the unadjusted model (linear regression coefficient 1.26, 95 % CI 0.14 to 2.38), but not in any of the extended models. Low job control was associated with elevated resting heart rate after adjustments for gender, age, BMI, and smoking (linear regression coefficient − 0.18, 95 % CI − 0.30 to − 0.02). However, there were no significant associations in the fully adjusted model. Conclusions: Low job control and job strain, but not job demands, were associated with elevated resting heart rate. However, the observed associations were modest and may be explained by confounding effects. Keywords: Work-related stress, Job strain, Job demands, Job control, Resting heart rate

- © 2019, The Author(s). Purpose: To assess whether working in preschools increases the risk of hearing-related symptoms and whether age, occupational noise, and stressful working conditions affect the risk. Methods: Questionnaire data on hearing-related symptoms were analysed in women aged 24–65 (4718 preschool teachers, and 4122 randomly selected general population controls). Prevalence and risk ratio (RR) of self-reported hearing loss, tinnitus, difficulty perceiving speech, hyperacusis and sound-induced auditory fatigue were assessed by comparing the cohorts in relation to age and self-reported occupational noise and stressful working conditions (effort–reward imbalance and emotional demands). RR was calculated using log-binomial regression models adjusted for age, education, income, smoking, hearing protection, and leisure noise. Incidence rates and incidence rate ratios (IRR) were calculated for retrospectively reported onset of all symptoms except sound-induced auditory fatigue. Results: Compared to the controls, preschool teachers had overall more than twofold RR of sound-induced auditory fatigue (RR 2.4, 95% confidence interval 2.2–2.5) and hyperacusis (RR 2.3, 2.1–2.5) and almost twofold for difficulty perceiving speech (RR 1.9, 1.7–2.0). Preschool teachers had a threefold IRR of hyperacusis (IRR 3.1, 2.8–3.4) and twofold for difficulty perceiving speech (IRR 2.4, 2.2–2.6). Significantly although slightly less increased RR and IRR were observed for hearing loss and tinnitus. RR and IRR were generally still increased for preschool teachers when stratified by age and occupational exposure to noise and stress. Conclusions: This large cohort study showed that working as preschool teacher increases the risk of self-reported hearing-related symptoms, indicating a need of preventative measures.

- In order to add to the existing knowledge about factors associated with retirement timing, in the car industry, it is useful to consider the psychosocial working conditions prior to retirement. This case-control study aimed to investigate relationships between psychosocial job factors and extended work after the age of 62 years among workers in the car industry in Sweden.A study invitation with a survey was sent to workers in one of Sweden's largest car manufacturing company, who were employed 2005-2015 and either retired at the age 55-62 years or working at 63 years or older. Psychosocial variables such as job demand-control (JDC) and effort-reward imbalance (ERI) were recorded through the survey. Multiple logistic regression models were used to investigate associations between psychosocial variables and retirement in 572 cases that had continued to work ≥ 63 years, and 771 controls who had retired at 62 or earlier.No associations were found between JDC-variables and retirement in the total sample or gender stratified analyses, but high demands-low control (high strain) was related to retirement before the age of 63 years in blue-collar workers. In contrast, high strain was related to continuing to work after 62 years for white-collar men and, high ERI was associated with extended work for the total sample of white-collar workers, and white-collar men, however these effects became non-significant in fully adjusted models.The relationships between psychosocial factors and extended work after 62 years were inconsistent, with high strain being related to retiring earlier for blue-collar workers.

- While risk of premature death is most pronounced among persons with severe mental illness, also milder conditions are associated with increased all-cause mortality. We examined non-psychotic mental (NPM) disorders and specific causes of natural death in a cohort of late adolescent men followed for up to 46 years.Prospective cohort study of Swedish males (n=1 784 626) who took part in structured conscription interviews 1968-2005. 74 525 men were diagnosed with NPM disorders at or prior to conscription. Median follow-up time was 26 years. HRs for cause-specific mortality were calculated using Cox proportional hazards models.Risks in fully adjusted models were particularly elevated for death by infectious diseases (depressive and neurotic/adjustment disorders (HR 2.07; 95%CI 1.60 to 2.67), personality disorders (HR 2.90; 95%CI 1.96 to 4.28) and alcohol-related and other substance use disorders (HR 9.02; 95%CI 6.63 to 12.27)) as well as by gastrointestinal causes (depressive and neurotic/adjustment disorders (HR 1.64; 95%CI 1.42 to 1.89), personality disorders (HR 2.77; 95%CI 2.27 to 3.38) and alcohol-related/substance use disorders (HR 4.41; 95%CI 3.59 to 5.42)).Young men diagnosed with NPM disorders had a long-term increased mortality risk, in particular due to infectious and gastrointestinal conditions. These findings highlight the importance of early preventive actions for adolescents with mental illness.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Large-scale studies examining future trajectories of marginalisation and health in adolescents with mental illness are scarce. The aim of this study was to examine if non-psychotic psychiatric disorders (NPDs) were associated with future indicators of marginalisation and mortality. We also aimed to determine whether these associations might be mediated by education level and attenuated by high cognitive ability. Design: This is a prospective cohort study with baseline data from the Swedish Conscription register. Setting: The study was carried out in Sweden from 1969 to 2005. Participants: All of the participants were 18-year-old men at mandatory conscription in Sweden between 1969 and 2005 (n=1 609 690). Measures: NPDs were clinically diagnosed at conscription. Cognitive ability was measured by a standardised IQ test at conscription. National register data covered information on welfare support, long-term unemployment, disability pension (DP) and mortality over a period of 1–36 years. Results: NPD at the age of 18 years was a predictor of future welfare support, OR 3.73 (95% CI 3.65 to 3.80); long-term unemployment, OR 1.97 (95% CI 1.94 to 2.01); DP, HR 2.95 (95% CI 2.89 to 3.02); and mortality, HR 2.45 (2.33–2.52). The adjusted models suggested that these associations were not confounded by fathers’ educational level, cognitive ability had only a minor attenuating effect on most associations and the mediating effect of own educational level was small. Conclusions: The present study underlines a higher prevalence of future adversities in young men experiencing NPDs at the age of 18 years. It also indicates that higher cognitive ability may work as a potential resilience factor against future marginalisation and mortality.

- Recent research suggests that the prevalence of early heart failure may be on the rise. Compromised mental health in adolescence may help to explain this phenomenon. We aimed to investigate whether nonpsychotic mental disorder and low stress resilience in late adolescence were associated with increased risk of early heart failure.A prospective cohort study of 18-year-old men (n=1,784,450) who enlisted 1968-2005. At the conscription examination, 74,522 individuals were diagnosed with nonpsychotic mental disorders. Stress resilience was rated by psychologists; values were trichotomized. The risk of heart failure during the 46-year follow-up was calculated with Cox proportional hazards models. Baseline comorbidities, BMI, blood pressure, fitness, IQ, and parental education were included in the models.Incident cases of heart failure (n=9962) were identified in the National Hospital Register. In fully adjusted models, increased risk of early heart failure was observed in males diagnosed with nonpsychotic mental disorders at conscription (hazard ratio (HR), 1.36; 95% confidence interval (CI), 1.25-1.47). The highest risk was seen among men with the risk factor alcohol/substance use (HR 1.90; 95% CI 1.59-2.28). Conscripts with the risk factor low stress resilience showed increased risk of heart failure compared to those with high scores (HR 1.41; 95% CI 1.30-1.53).Nonpsychotic mental disorder, as well as low stress resilience in late adolescence may be associated with increased risk of early heart failure. Adolescence is potentially an important time for mental health interventions that may reduce both short and long-term consequences.

- OBJECTIVES: The present study aimed to investigate whether different dimensions of psychosocial stress, as measured by the job demand-control model (JDC), were associated with increased risks of ischemic stroke and coronary heart disease (CHD). METHODS: A cohort of 75 236 male construction workers was followed from 1989-2004. Exposure to psychosocial stress was determined by a questionnaire answered in 1989-1993. Events of ischemic stroke and CHD were found by linkage to the Swedish Causes of Death and National Patient registers. Hazard ratios (HR) were obtained from Cox regression models, adjusted for age, smoking habits, body mass index and systolic blood pressure. RESULTS: There were 1884 cases of CHD and 739 cases of ischemic stroke. Regarding ischemic stroke, no association was found between job demands [HR 1.12, 95% confidence interval (95% CI) 0.89-1.40, highest versus lowest quintile] or job control (HR 1.04, 95% CI 0.82-1.32, lowest versus highest quintile). Regarding CHD, job demands were associated to CHD (HR 1.18, 95% CI 1.02-1.37, highest vs. lowest quintile), but no consistent trend was seen among quintiles. The results were inconsistent in relation to job control. The division of JDC into four categories showed no significant associations with either ischemic stroke or CHD. CONCLUSIONS: This exploratory study showed no significant associations between psychosocial work environment and ischemic stroke, and the associations between job demands and control and CHD were inconsistent and weak. The combination of job control and job demand showed no significant associations with either ischemic stroke or CHD.

- ABSTRACT: Background: This cross-sectional study explored relationships between psychosocial work environment, captured by job demand-control (JDC) and effort-reward imbalance (ERI), and seven cardiovascular heart disease (CHD) risk factors in a general population. Method: The sampled consists of randomly-selected men and women from Gothenburg, Sweden and the city’s surrounding metropolitan areas. Associations between psychosocial variables and biomarkers were analysed with multiple linear regression adjusted for age, smoking, education and occupational status. Results: The study included 638 men and 668 women aged 24–71. Analysis between JDC and CHD risk factors illustrated that, for men, JDC was associated with impaired scores in several biomarkers, especially among those in high strain jobs. For women, there were no relationships between JDC and biomarkers. In the analysis of links between ERI and CHD risk factors, most associations tested null. The only findings were raised triglycerides and BMI among men in the fourth quartile of the ERI-ratio distribution, and lowered LDL-cholesterol for women. An complementary ERI analysis, combining high/low effort and reward into categories, illustrated lowered triglycerides and elevated HDL-cholesterol values among women reporting high efforts and high rewards, compared to women experiencing low effort and high reward. Conclusions: There were some associations between psychosocial stressors and CHD risk factors. The cross-sectional design did not allow conclusions about causality but some results indicated gender differences regarding sensitivity to work stressors and also how the models might capture different psychosocial dimensions.
