Project description:The aim of this prospective study was to explore predictors of objective career success among Swedish women and men, focussing on gender differences. Data were drawn from the 2008 and 2010 waves of the Swedish Longitudinal Occupational Survey of Health (SLOSH) with a total of 3670 female and 2773 male participants. Odds ratios and 95% confidence intervals for job promotion and an above-average salary increase between 2008 and 2010 were obtained through binary logistic regression analyses. Individual and organisational factors measured in 2008 were used as predictors in analyses stratified by sex. Mutual adjustment was performed for these variables, as well as for labour market sector and staff category at baseline. In both sexes, younger age predicted both job promotion and an above-average salary increase. Job promotion was also in both sexes predicted by being part of decision-making processes, having conflicts with superiors, and being eager to advance. Furthermore, promotion was predicted by, among men, being educated to post-graduate level and having an open coping strategy and, among women, working >60 hours/week. An above-average salary increase was predicted in both sexes by having a university education. Postgraduate education, having children living at home, and being very motivated to advance predicted an above-average salary increase among women, as did working 51-60 hours/week and being part of decision-making processes in men. Gender differences were seen in several predictors. In conclusion, the results support previous findings of gender differences in predictors of career success. A high level of education, motivation to advance, and procedural justice appear to be more important predictors of career success among women, while open coping was a more important predictor among men.

Project description:ObjectivesTo examine the factor structure and to evaluate the longitudinal measurement invariance of the demand-control-support questionnaire (DCSQ), using the Swedish Longitudinal Occupational Survey of Health (SLOSH).MethodsA confirmatory factor analysis (CFA) and multi-group confirmatory factor analysis (MGCFA) models within the framework of structural equation modeling (SEM) have been used to examine the factor structure and invariance across time.ResultsFour factors: psychological demand, skill discretion, decision authority and social support, were confirmed by CFA at baseline, with the best fit obtained by removing the item repetitive work of skill discretion. A measurement error correlation (0.42) between work fast and work intensively for psychological demands was also detected. Acceptable composite reliability measures were obtained except for skill discretion (0.68). The invariance of the same factor structure was established, but caution in comparing mean levels of factors over time is warranted as lack of intercept invariance was evident. However, partial intercept invariance was established for work intensively.ConclusionOur findings indicate that skill discretion and decision authority represent two distinct constructs in the retained model. However removing the item repetitive work along with either work fast or work intensively would improve model fit. Care should also be taken while making comparisons in the constructs across time. Further research should investigate invariance across occupations or socio-economic classes.

Project description:PurposeDepression is a global health concern. High job demands, low job control, and the combination (high strain) are associated with depression. However, few longitudinal studies have investigated changed or repeated exposure to demands and control related to depression. We investigated how trajectories of exposure to job demands and control jointly influence subsequent depression.MethodsWe included 7949 subjects from the Swedish Longitudinal Occupational Survey of Health, who completed questionnaires of perceived job demands and control, and depressive symptoms from 2006 to 2014. None of them were depressed between 2006 and 2012. Univariate and joint group-based trajectory models identified groups with similar development of demands and control across 2006-2012. Logistic regression estimated the risk for symptoms of major depression in 2014 according to joint trajectory groups.ResultsThe joint trajectory model included seven groups, all with fairly stable levels of demands and control over time. Subjects in the high strain and active (high demands and high control) trajectories were significantly more likely to have subsequent major depressive symptoms compared to those having low strain, controlling for demographic covariates (OR 2.15; 95% Cl 1.24-3.74 and OR 2.04; 95% CI 1.23-3.40, respectively). The associations did not remain statistically significant after adjusting for previous depressive symptoms in addition to demographic covariates.ConclusionsThe results indicate that the levels of job demands and control were relatively unchanged across 6 years and suggest that long-term exposure to a high strain or active job may be associated with increased risk for subsequent depression.

Project description:BackgroundLong working hours and unpaid work are possible risk factors for depressive symptoms. However, little is known about how working hours influence the course of depressive symptoms. This study examined the influence of paid, unpaid working hours and total working hours on depressive symptoms trajectories.MethodsThe study was based on data from four waves of the Swedish Longitudinal Occupational Survey of Health (SLOSH 2008-2014). We applied group-based trajectory modelling in order to identify trajectories of depressive symptoms and studied paid and unpaid working hours and total working hours as risk factors.ResultsSix trajectory groups were identified with symptoms: 'very low stable', 'low stable', 'doubtful increasing', 'high decreasing', 'mild decreasing' and 'high stable'. More time spent on unpaid work was associated with the 'low stable' (OR 1.16, 95% CI 1.04 to 1.30) and the 'high stable (OR 1.40, 95% CI 1.18 to 1.65) symptom trajectories compared with being in the 'very low stable' symptom group. In addition, more total working hours was associated with a higher probability of having 'high decreasing' (OR 1.30, 95% CI 1.14 to 1.48) and 'high stable' (OR 1.22, 95% CI 1.01 to 1.47) symptoms, when adjusting for sex, age, civil status and socioeconomic status. The results, however, differed somewhat for men and women. More unpaid working hours was more clearly associated with higher symptom trajectories among women. More total working hours was associated with 'high stable' symptoms among women only.ConclusionsThis study supported heterogeneous individual patterns of depressive symptoms over time among the Swedish working population. The results also indicate that a higher burden of unpaid work and longer total working hours, which indicate a double burden from paid and unpaid work, may be associated with higher depressive symptom trajectories, especially among women.

Project description:PurposeThe Swedish Pancreatitis Cohort (SwePan) was designed to study long-term outcomes following an episode of acute pancreatitis. It can also be used to study various risk factors for developing acute pancreatitis.ParticipantsThe SwePan is a register-based nationwide matched cohort. It includes all Swedish cases of acute pancreatitis during 1990-2019. It contains 95 632 individuals with acute pancreatitis and 952 783 pancreatitis-free individuals matched on sex, age and municipality of residence. Follow-up was censored at death, emigration or end of study (31 December 2019). The dataset includes comprehensive information based on several registries, and includes diagnoses, prescribed medications and socioeconomic factors both prior to inclusion and during follow-up.Findings to dateDuring the study period, the number of cases of acute pancreatitis in Sweden has more than doubled from 1977 cases in 1990 to 4264 cases in 2019. The median age of first episode of acute pancreatitis has increased from 58 years (IQR 44-73 years) in 1990 to 64 years (IQR 49-76 years) in 2019. Cases with acute pancreatitis were generally less healthy compared with the pancreatitis-free individuals (Charlson Comorbidity Index of 0 in 59.2% and 71.4%, respectively).Future plansSwePan will be used to determine the incidence of acute pancreatitis in Sweden over time and assess long-term all-cause and cause-specific mortality after an episode of acute pancreatitis. Some examples of additional planned studies are (1) assessment of long-term risk of diabetes and (2) risk of malignancy in adjacent organs following acute pancreatitis and (3) assessment of risk factors for development of acute pancreatitis including various drugs.

Project description:PurposeThere is limited research on individuals undergoing self-initiated health examinations, and the Werlabs cohort will be a base for such research.ParticipantsAll individuals aged 18 or older who had undertaken a self-initiated health examination at Werlabs AB with at least one recorded value of creatinine or cholesterol in Sweden (from 1 January 2015 through 31 December 2023) was included. Medical history and anthropometric measurements were self-reported through an online questionnaire. We describe cohort baseline characteristics, demographic variables and cardiometabolic risk factors.Findings to dateThe study population includes 149 556 individuals who provided at least one health screening. The median (IQR) age was 43 (33-54) years and 54% were women. The most common self-reported chronic disease was hypertension (4.5%), followed by cardiovascular disease (0.9%) and 12.6% reported values of obesity. The prevalence was 2.1% for diabetes, 1.2% for kidney disease (including an estimated glomerular filtration rate of <60 mL/min/1.73 m2), 57.8% for a low-density lipoprotein cholesterol level of >3.0 mmol/L and 4.1% for anaemia (haemoglobin <120 g/L and <130 g/L for women and men, respectively). Interestingly, 1.5% of the individuals had a glucose measurement of >7.0 mmol/L, without reporting a previous diagnosis of diabetes. In an analysis restricted to 621 individuals with recorded blood pressure data between the age of 40 and 70 years and without existing cardiovascular disease, diabetes or kidney disease, 35,4% were classified as high or very high cardiovascular risk according to the 2021 ESC guidelines on cardiovascular disease prevention and with lipid levels that made them eligible for lipid-lowering therapy.Future plansThe Werlabs cohort comprises a rather healthy and young population that can provide opportunities for future studies on individuals undergoing self-initiated health examinations and has the potential to impact treatment of cardiometabolic risk factors.

Project description:PurposeThe Norwegian Survey of Health and Ageing (NORSE) was set up to provide internationally comparable data on ageing in Norway, which includes measured intrinsic capacity and cognitive function.ParticipantsNORSE is a population-based health examination study of seniors aged 60+ from the 1921-1958 birth cohorts in the former Norwegian county of Oppland, interviewed and examined during 2017-19 (N = 957, 16% response rate). NORSE is to some extent based on the SHARE-questionnaire ( share-project.org ), which includes work-related information, self-assessed and retrospective health, and expectations on longevity, quality of life, volunteering activities, consumption, and financial arrangements. In addition, several objective measures of intrinsic and cognitive capacity are included in NORSE.Findings to dateA shorter preferred life expectancy (PLE) was found to be associated with the prospects of a life with dementia and chronic pain. Motivation for retirement was found to be related to work-life experience and health. Social media was mostly used in the younger age groups and there was a tendency towards more use in the higher educational groups. NORSE incorporates questions on religion, and older women tend to have a higher degree of religiosity (proxied as self-assessed religiosity) than men in their 80s, but more similar (and lower levels) among those in their 60s.Future plansNORSE participants have allowed their data to be linked to National registry data and midlife health examination studies and thereby provide a longitudinal design as well as information on disability status, socioeconomic status, household and marital status, support to/from children and parents, and pension status.

Project description:PURPOSE:HELMi (Health and Early Life Microbiota) is a longitudinal, prospective general population birth cohort, set up to identify environmental, lifestyle and genetic factors that modify the intestinal microbiota development in the first years of life and their relation to child health and well-being. PARTICIPANTS:The HELMi cohort consists of 1055 healthy term infants born in 2016-2018 mainly at the capital region of Finland and their parents. The intestinal microbiota development of the infants is characterised based on nine, strategically selected, faecal samples and connected to extensive online questionnaire-collected metadata at weekly to monthly intervals focusing on the diet, other exposures and family's lifestyle as well as the health and growth of the child. Motor and cognitive developmental screening takes place at 18 months. Infant's DNA sample, mother's breast milk sample and both parent's spot faecal samples have been collected. FINDINGS TO DATE:The mean age of the mothers was 32.8 (SD 4.1) and fathers/coparents 34.8 (5.3) years at the time of enrolment. Seventeen percentage (n=180) of the infants were born by caesarean section. Just under half (49%) were firstborns; 50.7% were males. At 3 months of age, 86% of the babies were exclusively breastfed and 2% exclusively formula-fed. FUTURE PLANS:The current follow-up from pregnancy to first 24 months will be completed in March 2020, totalling to over 10 000 biological samples and over 50 000 questionnaire entries. The results are expected to identify environmental and host factors that affect early gut microbiota development and health, and hence give indications of how to prevent or reverse microbiota perturbations in infancy. This prospective cohort will be followed up further to identify how the early microbiota relates to later health outcomes, especially weight gain, infections and allergic and other chronic diseases.

Project description:PurposeThe Swedish Tattoo and Body Modifications Cohort (TABOO) cohort was established to provide an infrastructure for epidemiological studies researching the role of tattoos and other body modifications as risk factors for adverse health outcomes. It is the first population-based cohort with detailed exposure assessment of decorative, cosmetic, and medical tattoos, piercing, scarification, henna tattoos, cosmetic laser treatments, hair dyeing, and sun habits. The level of detail in the exposure assessment of tattoos allows for investigation of crude dose-response relationships.ParticipantsThe TABOO cohort includes 13 049 individuals that participated in a questionnaire survey conducted in 2021 (response rate 49%). Outcome data are retrieved from the National Patient Register, the National Prescribed Drug Register and the National Cause of Death Register. Participation in the registers is regulated by Swedish law, which eliminates the risk of loss to follow-up and associated selection bias.Findings to dateThe tattoo prevalence in TABOO is 21%. The cohort is currently used to clarify the incidence of acute and long-lasting health complaints after tattooing based on self-reported data. Using register-based outcome data, we are investigating the role of tattoos as a risk factor for immune-mediated disease, including hypersensitisation, foreign body reactions and autoimmune conditions.Future plansThe register linkage will be renewed every third year to update the outcome data, and we have ethical approval to reapproach the responders with additional questionnaires.
