Health, work, and personal-related predictors of time to return to work among employees with mental health problems

Purpose: To identify health-, personal- and work-related factors predictive of return to work (RTW) in employees sick-listed due to common mental health problems, such as, stress, depression, burnout, and anxiety. Methods: We distributed a baseline questionnaire to employees applying for sickness absence benefits at a large Danish welfare Department (n = 721). A total of 298 employees returned the questionnaire containing information on possible predictors of RTW. We followed up all baseline responders for a maximum of one year in a national registry of social transfer payments, including sickness absence benefits. Results: At baseline, about 9% of respondents had quit their job, 10% were dismissed and the remaining 82% were still working for the same employer. The mean time to RTW, measured from the first day of absence, was 25 weeks (median = 21) and at the end of follow-up (52 weeks) 85% had returned to work. In the fitted Cox model we found that fulfilling the DSM-IV criteria for depression predicted a longer time to RTW (HR: 0.61, CI: 0.45-0.84), whereas a better self-rated health predicted a shorter time to RTW (HR: 1.18, CI: 1.03-1.34). Employees working in the municipal (HR: 0.62, CI: 0.41-0.94) and private sector (HR: 0.65, CI: 0.44-0.96) returned to work slower compared to employees working in the governmental sector. Gender, education, cohabitation, size of workplace, low-back and upper-neck pain and employment at baseline did not predict RTW. Conclusion: Our results indicate that time to RTW is determined by both health- and work-related factors

Emotional demands at work and risk of hospital-treated depressive disorder in up to 1.6 million Danish employees : a prospective nationwide register-based cohort study

Objective Previous studies on effects of emotional demands on depression have relied on self-reported exposure data and lacked control for potential confounding by pre-employment risk factors for depression. This study used a register-based design to examine the risk of hospital-treated depressive disorder in relation to occupa-tional levels of emotional demands at work, furthermore addressing the role of risk factors for depression before workforce entry. Methods We analyzed data from two Danish register-based cohorts - Job Exposure Matrix Analyses of Psycho-social Factors and Healthy Ageing in Denmark (JEMPAD, N= 1 665 798) (17) and Danish Work Life Course Cohort (DaWCo, N=939 411), which link assessments of emotional demands by job exposure matrices to records of hospital-treated depressive disorder among employees aged 15-59 years at baseline (average follow up: 9.7 years in JEMPAD, 7.3 years in DaWCo). Potential confounders comprised sociodemographics, job control, work-related violence and physical demands at work. In DaWCo, we followed individuals from their entry into the workforce, and also included data on risk factors for depression before workforce entry (eg, parental income, education, and psychiatric diagnoses).Results Employees in occupations with high emotional demands had an increased risk of hospital-treated depres-sive disorder with confounder-adjusted hazard ratios of 1.32 [95% confidence interval (CI) 1.24-1.41] and 1.19 (95% CI 1.09-1.30) in JEMPAD and DaWCO, respectively. This association remained after controlling for risk factors before workforce entry.Conclusions This study suggests that employees in occupations with high emotional demands are at increased risk of hospital-treated depressive disorder. This increased risk was neither attributable to reporting bias nor explained by the included risk factors for depression recorded before workforce entry.Peer reviewe

Workplace sexual harassment and depressive symptoms:A cross-sectional multilevel analysis comparing harassment from clients or customers to harassment from other employees amongst 7603 Danish employees from 1041 organizations

Abstract Background Previous research has reported that sexual harassment can lead to reduced mental health. Few studies have focused on sexual harassment conducted by clients or customers, which might occur in person-related occupations such as eldercare work, social work or customer service work. This study examined the cross-sectional association between sexual harassment by clients or customers and depressive symptoms. We also examined if this association was different compared to sexual harassment conducted by a colleague, supervisor or subordinate. Further, we investigated if psychosocial workplace initiatives modified the association between sexual harassment by clients or customers and level of depressive symptoms. Methods We used data from the Work Environment and Health in Denmark cohort study (WEHD) and the Work Environment Activities in Danish Workplaces Study (WEADW) collected in 2012. WEHD is based on a random sample of employed individuals aged 18–64. In WEADW, organizational supervisors or employee representatives provided information on workplace characteristics. By combining WEHD and WEADW we included self-reported information on working conditions and health from 7603 employees and supervisors in 1041 organizations within 5 occupations. Data were analyzed using multilevel regression and analyses adjusted for gender, age, occupation and socioeconomic position. Results Exposure to workplace sexual harassment from clients or customers was statistically significantly associated with a higher level of depressive symptoms (2.05; 95% CI: 0.98–3.12) compared to no exposure. Employees harassed by colleagues, supervisors or subordinates had a higher mean level of depressive symptoms (2.45; 95% CI: 0.57–4.34) than employees harassed by clients or customers. We observed no statistically significant interactions between harassment from clients and customers and any of the examined psychosocial workplace initiatives (all p > 0.05). Conclusions The association between sexual harassment and depressive symptoms differed for employees harassed by clients or customers and those harassed by colleagues, supervisors or subordinates. The results underline the importance of investigating sexual harassment from clients or customers and sexual harassment by colleagues, supervisors or subordinates as distinct types of harassment. We found no modification of the association between sexual harassment by clients or customers and depressive symptoms by any of the examined psychosocial workplace initiatives

Workplace bullying and violence as risk factors for type 2 diabetes : a multicohort study and meta-analysis

The aim of this multicohort study was to examine whether employees exposed to social stressors at work, such as workplace bullying and violence, have an increased risk of type 2 diabetes. The study included 45,905 men and women (40-65 years of age and free of diabetes at baseline) from four studies in Sweden, Denmark and Finland. Workplace bullying and violence were self-reported at baseline. Incident diabetes was ascertained through national health and medication records and death registers. Marginal structural Cox models adjusted for age, sex, country of birth, marital status and educational level were used for the analyses. Nine per cent of the population reported being bullied at work and 12% were exposed to workplace violence or threats of violence. Bullied participants had a 1.46 (95% CI 1.23, 1.74) times higher risk of developing diabetes compared with non-bullied participants. Exposure to violence or threats of violence was also associated with a higher risk of diabetes (HR 1.26 [95% CI 1.02, 1.56]). The risk estimates attenuated slightly when taking BMI into account, especially for bullying. The results were similar for men and women, and were consistent across cohorts. We found a higher risk of incident type 2 diabetes among employees exposed to bullying or violence in the workplace. Further research is needed to determine whether policies to reduce bullying and violence at work may reduce the incidence of type 2 diabetes in working populations. Research on the mechanisms is also highly warranted.Peer reviewe
