Introduction: Sickness absence (SA) has been shown to be associated with several negative consequences, both for the affected individual as well as for society on the whole, in terms of economic loss. The most common reason for SA is SA due to common mental disorders (CMDs). Previous studies have indicated that there is an association between exposure to work-related offensive behaviours, such as harassment, bullying, violence and threats of different kinds and CMDs. However, the mechanistic pathway in this association is still largely unknown. For example, the associations between exposure to offensive or abusive behaviours and health outcomes may partially be explained by individual characteristics, including genetic predispositions and early experiences. The aim of the present study was to investigate the role of familial factors (genetics and shared early-life environment) and neuroticism in the associations between exposure to work-related violence/threats and harassment/bullying, and SA due to CMDs.

Method: The study sample included 8795 twin individuals from the Swedish Twin project of Disability pension and Sickness absence (STODS), including survey data from the Study of Twin Adults: Genes and Environment (STAGE) linked to national register data. Self-reported work-related violence and/or threats and work-related harassment including bullying and register data on SA due to CMDs were analysed using logistic regression on the whole sample, and conditional logistic regression among complete same-sex twin pairs discordant on exposures. Individuals were followed for a maximum of 13 years or until their first incident SA spell due to CMD. Interactions between neuroticism and exposures were assessed using both multiplicative and additive interaction analyses.

Results: Exposure to work-related violence/threats were associated with higher odds of SA due to CMDs when adjusting for age, sex, marital status, children living at home, education, type of residential area, work characteristics, and symptoms of depression and burnout (OR 2.11, 95% CI 1.52-2.95). Higher odds of SA due to CMDs were also found for exposure to harassment/bullying (OR 1.52, 95% CI 1.10-2.11) and a combined indicator of exposure to either of the kinds of exposure or exposure to both kinds, i.e. violence/threats and/or harassment/bullying (OR 1.98 95% CI 1.52-2.59), compared with the unexposed. Analyses of twin pairs discordant on exposure, using the unexposed twin sibling as reference, showed somewhat reduced ORs that were no longer statistically significant for all exposures. No multiplicative interaction was found between neuroticism and exposure to work-related violence/threats, or harassment. However, a statistically significant additive interaction was found between neuroticism and exposure to violence/threats, with higher odds of SA due to CMDs in the group scoring lower on neuroticism.

Conclusion: Exposure to work-related offensive behaviours were associated with SA due to CMDs. The results of the matched twin pair analysis indicated that these associations may be confounded by familial factors. In addition, an interaction effect between violence/threats and neuroticism was found. Thus, future studies investigating associations and causality between offensive behaviours at work and mental health-related outcomes should, when possible, consider familial factors and neuroticism.

Background The link between workplace bullying and poor mental health is well-known. However, little is known about the prospective and potentially reciprocal association between workplace bullying and mental health-related sickness absence. This 2-year prospective study examined bidirectional associations between exposure to workplace bullying and sickness absence due to common mental disorders (SA-CMD) while controlling for confounding factors from both work and private life.

Methods The study was based on propensity score-matched samples (N = 3216 and N = 552) from the Swedish Longitudinal Occupational Survey of Health, using surveys from years 2012, 2014 and 2016. Self-reported exposure to workplace bullying was linked to registry-based information regarding medically certified SA-CMD (≥ 14 consecutive days). The associations were examined by means of Cox proportional hazards regression and via conditional logistic regression analysis. Hazard ratios and odds ratios with 95% confidence intervals were estimated.

Results Exposure to workplace bullying was associated with an increased risk of incident SA-CMD (HR: 1.3, 95% CI: 1.0–1.8), after accounting for the influence of job demands, decision authority, previous SA-CMD, as well as other sociodemographic covariates. However, we found no statistically significant association between SA-CMD and subsequent workplace bullying (OR 1.2, 95% CI 0.7–1.9).

Conclusions The results support an association between self-reported workplace bullying and SA-CMD, independent of other sociodemographic factors and workplace stressors. Preventing workplace bullying could alleviate a share of the individual and societal burden caused by SA globally.

Background: With climate change Northern areas of the globe are expected to have less daylight during winters due to less snow and more cloudiness. While wintertime has been linked to mental health problems, the role of wintertime daylight has been scarcely studied. We examined longitudinal associations for wintertime objective exposure to global radiation and self-reported daylight exposure with symptoms of depression and sleep problems.

Methods: Our analytical sample included 15,619 respondents from three Swedish Longitudinal Occupational Surveys of Health (2012, 2014 and 2016). Objective exposure was global radiation (MJ/m², November-January and November-February). Subjective exposure was based on self-reported time spent outdoors in daylight (<1 h vs. ≥ 1 h, November-January). Symptoms of depression were evaluated using a six-item subscale of the (Hopkins) Symptom Checklist. Fixed-effects method with conditional logistic regression controlled for time-invariant participant characteristics by design and time-varying covariates were added into models.

Results: One unit increase in the four-month averaged global radiation was associated with lower odds of depressive symptoms (OR 0.69, 95 % CI 0.52–0.91). These findings were confirmed using four-month cumulative exposure (OR 0.91, 95 % CI 0.85–0.98). Individuals reporting ≥ 1 h exposure to daylight during winter months were less likely to report depressive symptoms (OR 0.72, 95 % CI 0.60–0.82) compared to time when their exposure was < 1 h. Higher three-month exposure to global radiation suggested a protective association for sleep problems.

Conclusion: These findings suggest that higher exposure to daylight during winters may contribute to lower likelihood of depression symptoms.

Aims Spending time in natural environments has been linked to mental health benefits, and may have been an important resilience factor during the COVID-19 pandemic, but longitudinal studies are limited. This longitudinal study aimed to investigate the development of nature-related habits and their relationship to different mental health outcomes before and during early and later phases of COVID-19 (2019–2022). Furthermore, the buffering potential of nature-related habits on effects of major life events on mental health outcomes was investigated.

Subject and methods A subsample of the Swedish Longitudinal Occupational Survey of Health (SLOSH) was studied during 2018–2022, including follow-ups in early 2021 (n  = 1902) and 2022 (n = 1580). Visits to various types of nature, mental health outcomes (symptoms of depression, anxiety, loneliness, sleep difficulties), and major life events were analyzed across the study period while controlling for confounders.

Results Greater overall engagement in nature visits, particularly visiting forests or using one’s garden, was associated with lower levels of depression, anxiety, loneliness, and sleep problems in early 2021 and 2022.

Importantly, changes in nature visits were consistently negatively associated with investigated mental health outcomes across the study period. All nature visits, except for garden time, increased in the long term (2019–2022). Visiting forests also increased in the short term, while overall nature visits initially decreased (2019–2020).

Conclusion Generally, nature visits increased longitudinally and were associated with better mental health outcomes during the COVID-19 pandemic. This underscores the importance of green- and blue-space accessibility for facilitating outdoor recreation in natural environments, to support resilience and public health during pandemics.

Objectives: The aim of this study was to investigate associations between exposure to work-related violence/threats and harassment, and future sickness absence (SA) due to common mental disorders (CMDs), taking familial factors (shared genetics and early-life environment) and neuroticism into account. Methods: The study sample included 8795 twin individuals from the Swedish Twin Project of Disability Pension and Sickness Absence (STODS), including survey data from the Study of Twin Adults: Genes and Environment (STAGE). Self-reported work-related violence and/or threats as well as work-related harassment (including bullying) and national register data on SA due to CMDs were analyzed using standard logistic regression, and conditional logistic regression among complete twin pairs discordant on exposures. Individuals were followed for a maximum of 13 years. Interactions between neuroticism and exposures were assessed using both multiplicative and additive interaction analyses. Results: Exposure to work-related violence/threats was associated with higher odds of SA due to CMDs when adjusting for age, sex, marital status, children, education, type of living area, work characteristics, and symptoms of depression and burnout (OR 2.11, 95% CI 1.52-2.95). Higher odds of SA due to CMDs were also found for exposure to harassment (OR 1.52, 95% CI 1.10-2.11) and a combined indicator of exposure to violence/threats and/or harassment (OR 1.98, 95% CI 1.52-2.59), compared with the unexposed. Analyses of twins discordant on exposure, using the unexposed co-twin as reference, showed reduced ORs. These ORs were still elevated but no longer statistically significant, potentially due to a lack of statistical power. No multiplicative interaction was found between neuroticism and exposure to work-related violence/threats, or harassment. However, a statistically significant additive interaction was found between neuroticism and exposure to violence/threats, indicating higher odds of SA due to CMDs in the group scoring lower on neuroticism. Conclusions: Exposure to work-related offensive behaviors was associated with SA due to CMDs. However, the results indicated that these associations may be partly confounded by familial factors. In addition, an interaction between exposure and neuroticism was suggested. Thus, when possible, future studies investigating associations and causality between offensive behaviors at work and mental health-related outcomes, should consider familial factors and neuroticism.

Objective: The association of proximity of alcohol outlets to the workplace with problem drinking has not been previously studied. We examined longitudinal associations of living and working in proximity to alcohol outlets with problem drinking. Method: The data consisted of 13,306 employed respondents to the Swedish Longitudinal Occupational Survey of Health between 2012 and 2018. Road distances from the respondents' home and workplace to the nearest liquor outlet, beer outlet, and bar were calculated by Statistics Sweden. We used distance variables both as categorized, to indicate changes in distance, and as continuous variables. Self-reported problem drinking was assessed using modified Cut-Annoyed-Guilty-Eye (CAGE) questions. Binomial logistic regression with generalized estimating equation was used to examine the associations. Results: A decrease (vs. remained unchanged) in the distance from home to a liquor outlet was associated with a higher likeli- hood of problem drinking (odds ratio = 1.21, 95% confidence interval [1.02, 1.45]). A protective association for problem drinking was observed when the distance from home to a beer outlet increased (vs. remained unchanged) (0.65 [0.44, 0.95]). A decrease (vs. remained unchanged) in the distance from work to a bar was also associated with a higher likelihood of problem drinking (1.37 [1.00, 1.88]). The likelihood of problem drinking was increased also per 1-km decrease in distance from home to liquor outlets (1.01 [1.00, 1.02]), risk estimates being higher for women than for men. Conclusions: Alcohol outlet proximity to the workplace could be an additional determinant of harmful alcohol consumption behavior. Reducing the number of on- and off-premise alcohol outlets could reduce the level of harmful alcohol consumption.

Background: Workplace offensive behaviours, such as violence and bullying, have been linked to psychological symptoms, but their potential impact on suicide risk remains unclear. We aimed to assess the association of workplace violence and bullying with the risk of death by suicide and suicide attempt in multiple cohort studies. Methods: In this multicohort study, we used individual-participant data from three prospective studies: the Finnish Public Sector study, the Swedish Work Environment Survey, and the Work Environment and Health in Denmark study. Workplace violence and bullying were self-reported at baseline. Participants were followed up for suicide attempt and death using linkage to national health records. We additionally searched the literature for published prospective studies and pooled our effect estimates with those from published studies. Findings: During 1 803 496 person-years at risk, we recorded 1103 suicide attempts or deaths in participants with data on workplace violence (n=205 048); the corresponding numbers for participants with data on workplace bullying (n=191 783) were 1144 suicide attempts or deaths in 1 960 796 person-years, which included data from one identified published study. Workplace violence was associated with an increased risk of suicide after basic adjustment for age, sex, educational level, and family situation (hazard ratio 1.34 [95% CI 1.15-1.56]) and full adjustment (additional adjustment for job demands, job control, and baseline health problems, 1.25 [1.08-1.47]). Where data on frequency were available, a stronger association was observed among people with frequent exposure to violence (1.75 [1.27-2.42]) than occasional violence (1.27 [1.04-1.56]). Workplace bullying was also associated with an increased suicide risk (1.32 [1.09-1.59]), but the association was attenuated after adjustment for baseline mental health problems (1.16 [0.96-1.41]). Interpretation: Observational data from three Nordic countries suggest that workplace violence is associated with an increased suicide risk, highlighting the importance of effective prevention of violent behaviours at workplaces.

Background: Individuals' lives have been substantially affected by the COVID-19 pandemic. We aimed to describe changes in psychosocial work environment and mental health and to investigate associations between job insecurity and mental ill-health in relation to changes in other psychosocial work factors, loneliness and financial worries.

Methods: A sub-sample of individuals from the eighth Swedish Longitudinal Occupational Survey of Health answered a web-based survey in early 2021 about current and pandemic-related changes in health, health behaviours, work and private life. We investigated participants working before the pandemic (N=1231) in relation to standardised measures on depression, anxiety and loneliness, together with psychosocial work factors, in descriptive and logistic regression analyses.

Results: While 9% reached the clinical threshold for depression and 6% for anxiety, more than a third felt more worried, lonelier or in a low mood since the start of the pandemic. Two per cent had been dismissed from their jobs, but 16% experienced workplace downsizings. Conditioning on socio-demographic factors and prior mental-health problems, the 8% experiencing reduced job security during the pandemic had a higher risk of anxiety, but not of depression, compared to employees with unaltered or increased job security. Loneliness and other psychosocial work factors explained more of the association than objective measures of job insecurity and financial worries.

Conclusions: Reduced job security during the COVID-19 pandemic seems to have increased the risk of anxiety among individuals with a strong labour market attachment, primarily via loneliness and other psychosocial work factors. This illustrates the potentially far-reaching effects of the pandemic on mental health in the working population.

Background: The evidence is insufficient regarding the association between organizational downsizing and employee mental health. Our aim was to analyze trajectories of prescribed sedatives and anxiolytics with a sufficiently long follow-up time to capture anticipation, implementation and adaption to a downsizing event among stayers, changers and those who become unemployed compared to unexposed employees.

Method: Residents in Sweden aged 20-54 years in 2007, with stable employment between 2004 and 2007, were followed between 2005 and 2013 (n = 2,305,795). Employment at a workplace with staff reductions >= 18% between two subsequent years in 2007-2011 (n = 915,461) indicated exposure to, and timing of, downsizing. The unexposed (n = 1,390,334) were randomized into four corresponding sub-cohorts. With generalized estimating equations, we calculated the odds ratios (OR) of purchasing prescribed anxiolytics or sedatives within nine 12-month periods, from four years before to four years after downsizing. In order to investigate whether the groups changed their probability of purchases over time, odds ratios (OR) and their 95% confidence intervals (95% CI) were calculated contrasting the prevalence of purchases during the first and the last 12-month period within four time periods for each exposure group.

Results: The odds of purchasing psychotropic drugs increased more for changers (sedatives OR 1.08, 95% CI 1.05-1.11) and unemployed (anxiolytics OR 1.08, 95% CI 1.03-1.14), compared to unexposed before downsizing, while for stayers purchases increased more than for unexposed during and after downsizing. Among those without previous sickness absence, stayers increased their purchases of psychotropic drugs from the year before the event up to four years after the event.ConclusionThis study indicates that being exposed to downsizing is associated with increased use of sedatives and anxiolytics, before the event among those who leave, but especially thereafter for employees who stay in the organization.

Objectives The aim of this prospective cohort study was to investigate if exposure to work-related violence and/or threats of violence predict certified sickness absence due to mental disorders.

Methods Information on work-related exposure to violence and/or threats of violence were derived from the biannual Swedish Longitudinal Occupational Survey of Health (SLOSH) study 2012-2016, including individuals in paid work across Sweden and from different occupations/sectors (n = 16,339). Certified sickness absence due to mental disorders were ascertained from register data from the Swedish Social Insurance Agency. Odds ratios of certified sickness absence due to mental disorders according to exposure to work-related violence were estimated using multiple logistic regression. Several potential confounding variables, such as demographic and socio-economic factors, age, sex, cohabitation, children living at home, socio-economic status, educational level, as well as other types of psychosocial work environmental factors, were adjusted for in the analyses.

Results In the total study sample, 9% reported exposure to violence and/or threats of violence and the prevalence of sickness absence due to mental disorders was 5%. Exposure to work-related violence and/or threats of violence was associated prospectively with certified sickness absence due to mental disorders (odds ratio 1.46, 95% confidence interval 1.17-1.82, p < 0.01). Analysis of possible interaction showed no difference in association when comparing women to men and different age groups.

Conclusions Exposure to work-related violence and/or threats of violence appear to increase the odds of certified sickness absence due to mental disorders. Preventive measures aiming to lower the risk of exposure is thus of great importance.
