ABSTRACT: BACKGROUND: Adverse psychosocial working environments characterized by job strain (the combination of high demands and low control at work) are associated with an increased risk of depressive symptoms among employees, but evidence on clinically diagnosed depression is scarce. We examined job strain as a risk factor for clinical depression. METHOD: We identified published cohort studies from a systematic literature search in PubMed and PsycNET and obtained 14 cohort studies with unpublished individual-level data from the Individual-Participant-Data Meta-analysis in Working Populations (IPD-Work) Consortium. Summary estimates of the association were obtained using random-effects models. Individual-level data analyses were based on a pre-published study protocol. RESULTS: We included six published studies with a total of 27 461 individuals and 914 incident cases of clinical depression. From unpublished datasets we included 120 221 individuals and 982 first episodes of hospital-treated clinical depression. Job strain was associated with an increased risk of clinical depression in both published [relative risk (RR) = 1.77, 95% confidence interval (CI) 1.47-2.13] and unpublished datasets (RR = 1.27, 95% CI 1.04-1.55). Further individual participant analyses showed a similar association across sociodemographic subgroups and after excluding individuals with baseline somatic disease. The association was unchanged when excluding individuals with baseline depressive symptoms (RR = 1.25, 95% CI 0.94-1.65), but attenuated on adjustment for a continuous depressive symptoms score (RR = 1.03, 95% CI 0.81-1.32). CONCLUSIONS: Job strain may precipitate clinical depression among employees. Future intervention studies should test whether job strain is a modifiable risk factor for depression.

2 Article Long working hours and depressive symptoms: systematic review and meta-analysis of published studies and unpublished individual participant data. 2018

ABSTRACT: Objectives This systematic review and meta-analysis combined published study-level data and unpublished individual-participant data with the aim of quantifying the relation between long working hours and the onset of depressive symptoms. Methods We searched PubMed and Embase for published prospective cohort studies and included available cohorts with unpublished individual-participant data. We used a random-effects meta-analysis to calculate summary estimates across studies. Results We identified ten published cohort studies and included unpublished individual-participant data from 18 studies. In the majority of cohorts, long working hours was defined as working ≥55 hours per week. In multivariable-adjusted meta-analyses of 189 729 participants from 35 countries [96 275 men, 93 454 women, follow-up ranging from 1-5 years, 21 747 new-onset cases), there was an overall association of 1.14 (95% confidence interval (CI) 1.03-1.25] between long working hours and the onset of depressive symptoms, with significant evidence of heterogeneity (I

3 Article Measures against preschool noise and its adverse effects on the personnel: an intervention study. 2014

Sjödin, Fredrik / Kjellberg, Anders / Knutsson, Anders / Landström, Ulf / Lindberg, Lennart. ·Center for Built Environment, University of Gävle, 80176, Gävle, Sweden, fredrik.sjodin@hig.se. ·Int Arch Occup Environ Health · Pubmed #23269469.

ABSTRACT: PURPOSE: The aim of the study was to analyze the exposure effects of different types of noise measures carried out at preschools. The project was carried out as an intervention study. METHODS: The investigation included 89 employees at 17 preschools in the northern part of Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments in each preschool. The adverse effects on the employees were analyzed with validated questionnaires and saliva cortisol samples. Evaluations were made before and 1 year after the first measurement. Between the two measurements, measures were taken to improve the sound environments at the preschools. RESULTS: The effects of the measures varied a lot, with respect to both the sound environments and health. Regarding acoustical measures, significant changes were seen for some of the variables analyzed. For most of the tested effects, the changes, however, were very small and non-significant. The effects of organizational measures on the objective and subjective noise values were in overall less pronounced. CONCLUSION: Acoustical measures improved the subjectively rated sound environment more than organizational measures. This may be due to the high work effort needed to implement organizational measures. Even though the sound level was not lower, the personnel experienced improvements of the sound environment.

4 Article Noise and stress effects on preschool personnel. 2012

Sjödin, Fredrik / Kjellberg, Anders / Knutsson, Anders / Landström, Ulf / Lindberg, Lennart. ·Faculty of Building, Energy and Environmental Engineering, Laboratory of Environmental Psychology, University of Gävle, Gävle, Sweden. fredrik.sjodin@hig.se ·Noise Health · Pubmed #22918147.

ABSTRACT: The aim of the study was to analyze the presence of stress-related health problems among preschool employees and the way in which these reactions are related to noise and other work parameters. The investigation included 101 employees at 17 preschools in Umeå County, located in northern Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments from each preschool. The adverse effects on the employees were analyzed by use of different validated questionnaires and by saliva cortisol samples. Stress and energy output were pronounced among the employees, and about 30% of the staff experienced strong burnout syndromes. Mental recovery after work was low, indicated by remaining high levels of stress after work. The burnout symptoms were associated with reduced sleep quality and morning sleepiness. Cortisol levels supported the conclusion about pronounced daily stress levels of the preschool employees.
