Contamination of depressional wetlands in the Mpumalanga Lake District of South Africa near a global emission hotspot

The Mpumalanga Lake District (MLD) of South Africa hosts a regionally unique cluster of water bodies of great importance for wetland biodiversity. It is also located close to a global hotspot for coal-fired power station emissions but the local impacts from these sources of pollution are poorly understood. Sediment cores from three contrasting wetlands were 210Pb dated and analysed for a range of contaminants linked to fossil fuel combustion, including trace elements, Hg, sulphur and spheroidal carbonaceous fly-ash particles (SCPs). At the two sites with pre-industrial (1900) baseline sediments, Pb, Zn and especially Cr concentrations and fluxes showed significant increases in the impact period (post-1975). Mercury showed the greatest proportional increase in flux (>4-fold) of all trace metals. Mercury and sulphur concentrations and fluxes showed highly significant correlations with emissions over the corresponding periods, while SCPs in sediments also closely tracked emissions. In a global context, levels of sediment contamination are relatively minor compared with other heavily industrialised regions, with only Cr exceeding the sediment Probable Effects Concentration for biological impact post-1975. Despite the relatively large increases in Hg, concentrations do not reach the Threshold Effects Concentration. The unexpectedly low levels of contamination may be due to i) low levels of many trace contaminants in South African coals compared to global averages, ii) prevailing recirculation patterns which transport pollution away from the study area during the wet season, minimising wet deposition, and iii) pollutant remobilisation through desiccation of wetlands or volatilization. The effects of hydrology and sediment accumulation rates lead to differential transport and preservation of organic-associated and more volatile contaminants (e.g. Hg, S) relative to non-volatile trace elements in wetlands of the MLD. The greatest fluxes of Hg and S are recorded in the site with the highest catchment: lake area ratio, lowest salinity and greatest sediment organic matter content.

Examining variation in the relationship between disability and physical activity across Australian local government areas

Understanding the relationship between disability and physical activity and whether it differs across local government jurisdictions may aid in the development of placed-based approaches to reducing disability-related inequalities in physical activity. The objectives of this study were to examine the association between disability and physical activity and assess whether this association varied between Australian Local Government Areas. The sample included 13,315 participants aged 18-64 years from the Household Income and Labour Dynamics Australia Survey, 2017. Participants self-reported disability and physical activity. Linear mixed-effects models estimated the association between disability and physical activity. People with disability reported less physical activity per week. We did not find evidence that this association varied across LGAs. Our findings do not add evidence towards local government-based approaches in Australia to reducing physical activity inequalities between people with and without a disability.

Poor psychosocial job conditions increase sickness absence: evidence from the PATH Through Life Mid-Aged Cohort

OBJECTIVES

Evidence is mounting that poor psychosocial job conditions increase sickness absence, but there is a need for further rigorous prospective research to isolate the influence of psychosocial job quality from other measured and unmeasured confounders. This study used four waves of prospective longitudinal data (spanning 12 years) to investigate the extent to which increases in poor psychosocial job quality are associated with greater relative risk of day of sickness absence.

DESIGN

Prospective cohort study.

SETTING

Data were from the Australian PATH Through Life cohort study. The analyses adopted hybrid-regression estimations that isolated the effect of within-person change in psychosocial job quality on sickness absence over time.

PARTICIPANTS

Participants were from a midlife cohort aged 40-44 at baseline (7644 observations from 2221 participants).

PRIMARY OUTCOME MEASURE

Days sickness absence in the past 4 weeks.

RESULTS

The results show that after adjusting for a wide range of factors as well as unmeasured between-person differences in job quality, each additional psychosocial job adversity was associated with a 12% increase in the number of days of sickness absence (relative risk ratio: 1.12, 95% CI 1.03 to 1.21). Increases in psychosocial job adversity were also related to greater functional impairment (relative risk ratio: 1.17 (1.05 to 1.30)).

CONCLUSION

The results of this study strengthen existing research highlighting the importance of addressing poor psychosocial job quality as a risk factor for sickness absence.

"Is Life Worth Living?": The Role of Masculinity in the Way Men Aged Over 80 Talk About Living, Dying, and Suicide

Men aged 85 years and over have the highest rate of suicide of any age or gender group in Australia. However, little is known about their trajectory toward suicide. The objective of this study was to understand the role of masculine norms and other life factors in the suicidality of older men. Thirty-three men aged 80 years or more took part in a semistructured focus group or interview, and/or completed a survey. Participants were asked about the issues facing older men, well-being and aging, physical health challenges, social support, mental health and help-seeking, and suicide and suicide prevention. Five themes emerged: "finding out we're not invincible," "active and tough," "strong silent types," "decision makers," and "right to die." Participants spoke about masculine norms that had influenced their lives as providers and decision makers, and now influenced how they coped with aging and their journey toward death. For some participants, suicide was seen to be a rational alternative to dependence in their final years. Suicide prevention should adopt a gendered approach and be cognizant of the influence of gender roles and masculinity in older men's lives. Further research and prevention efforts should be mindful of the impact of masculine norms of self-reliance and control on an older man's decision to end his life. Suicide prevention efforts should work to reduce stigma around the challenges of aging, maximize opportunities for control, facilitate social connection, and improve residential aged care.

1198The gendered associations between poverty, marital status, and mental health in older Australians

Background

Compared to men, older women have poorer mental health and are more vulnerable to poverty. Few studies have examined how gender, marital status and poverty are inter-related and are associated with mental health among this group.

Methods

Drawing on 17 waves of the Housing Income and Labour Dynamics in Australia survey, fixed-effects regression analysis was utilised to examine associations between: (1) relative poverty (<50% median household income) and mental health (MHI-5); (2) marital status and poverty, among Australians aged 65+years. Effect measure modification (EMM) of the association between relative poverty and mental health by marital status was also assessed.

Results

Relative poverty was associated with poorer mental health among women (−0.62, 95%CI−1.06,−0.18), but not men. Being divorced/separated was associated with increased odds of relative poverty for women (OR 3.93, 95%CI 2.54,6.06) but not men, and widowhood was associated with relative poverty in women (OR 4.23, 95%CI 3.37,5.29), and men (OR 2.22, 95%CI 1.62,3.05). There was no evidence of EMM of the relationship between relative poverty and mental health by marital status for either gender.

Conclusions

This study provides evidence that relative poverty is a major determinant of mental health in older Australian women. Addressing gender inequities in lifetime savings, as well as in division of acquired wealth post marital loss, may mitigate these disparities.

Key messages

A gendered double burden of mental health issues and poverty exists for older Australian women, requiring urgent policy attention.

Health Literacy in Male-Dominated Occupations

Low levels of health literacy are associated with poorer health outcomes. Both individual- and social-level factors have been identified as predictors of low health literacy, and men are known to have lower health literacy than women. Previous research has reported that men working in male-dominated occupations are at higher risk of accidents, injury, and suicide than other population groups, yet no study to date has examined the effect of gendered occupational contexts on men’s health literacy. The current article examined the association between occupational gender ratio and health literacy among Australian males. The Australian Longitudinal Study on Male Health (Ten to Men) was used to examine associations between occupational gender ratio (measured in Wave 1) and health literacy (measured in Wave 2) across three subscales of the Health Literacy Questionnaire. Multivariable linear regression analyses were used and showed that the more male dominated an occupational group became, the lower the scores of health literacy were. Results for the different subscales of health literacy for the most male-dominated occupational group, compared to the non-male-dominated group were: ability to find good health information, (Coef. −0.80, 95% CI [−1.05, −0.54], p < .001); ability to actively engage with health-care providers, (Coef. −0.35, 95% CI [−0.62, −0.07], p = .013); and feeling understood and supported by health-care providers, (Coef. −0.48, 95% CI [−0.71, −0.26],p = < .001). The results suggest the need for workplace interventions to address occupation-level factors as an influence on health literacy among Australian men, particularly among the most male-dominated occupational groups.

Overt acts of perceived discrimination reported by British working-age adults with and without disability

BACKGROUND

Exposure to discrimination can have a negative impact on health. There is little robust evidence on the prevalence of exposure of people with disabilities to discrimination, the sources and nature of discrimination they face, and the personal and contextual factors associated with increased risk of exposure.

METHODS

Secondary analysis of de-identified cross-sectional data from the three waves of the UK's 'Life Opportunities Survey'.

RESULTS

In the UK (i) adults with disabilities were over three times more likely than their peers to be exposed to discrimination, (ii) the two most common sources of discrimination were strangers in the street and health staff and (iii) discrimination was more likely to be reported by participants who were younger, more highly educated, who were unemployed or economically inactive, who reported financial stress or material hardship and who had impairments associated with hearing, memory/speaking, dexterity, behavioural/mental health, intellectual/learning difficulties and breathing.

CONCLUSIONS

Discrimination faced by people with disabilities is an under-recognised public health problem that is likely to contribute to disability-based health inequities. Public health policy, research and practice needs to concentrate efforts on developing programs that reduce discrimination experienced by people with disabilities.

Do psychosocial job stressors differentially affect the sleep quality of men and women? A study using the HILDA Survey

The aim of this study was to investigate whether gender was an effect modifier of the relationship between three psychosocial job stressors and sleep quality, in a representative sample of 7280 employed Australians. We conducted linear regressions and effect measure modification analyses. Low job control, high job demands and low job security were associated with poorer sleep quality. There was evidence of effect modification of the relationship between job security and sleep quality by gender on the additive scale, indicating that the combined effect of being male and having low job security is greater than the summed interactive effect.

The impact of transitions from employment to retirement on suicidal behaviour among older aged Australians

PURPOSE

Transition from employment to retirement may be detrimental to mental health, and associated with suicidal behaviour. This study investigated the association between employment and retirement status and suicidal behaviour among older aged Australians.

METHODS

This study was based on the '45 and Up Study', a large prospective cohort study of participants from New South Wales (Australia) aged 45 years and older (N = 267,153), followed up over the period 2006-2018. The risk of attempted suicide and suicide was compared between categories of employment and retirement status in a series of recurrent event survival analysis models adjusting for identified time variant and invariant confounders.

RESULTS

Compared to those who were employed, the risk of attempted suicide was higher among those who were not in the labour force and not retired (predominantly those who were sick or disabled, or carers) (HR = 1.97-95% CI 1.49-2.62), those who retired involuntarily (HR = 1.35-95% CI 1.03-1.77), and to a lesser extent those unemployed (HR = 1.31-95% CI 0.89-1.92). Risk of attempted suicide among those who retired voluntarily was similar to those who remained employed (HR = 1.09-95% CI 0.82-1.45). A similar pattern was evident for suicide, with a higher risk of suicide among those who were not in the labour force or retired, and those who retired involuntarily, compared to those who remained employed; however, these differences were not statistically significant.

CONCLUSION

Transition from employment to retirement may be an important precipitating factor for suicidal behaviour, affected by current and previous mental health status. Services and programs facilitating continued or re-employment in older age, and adjustment to the transition from employment to retirement may prevent suicidal behaviour.

Gender Equality and Health in High-Income Countries: A Systematic Review of Within-Country Indicators of Gender Equality in Relation to Health Outcomes

Background: Gender equality is recognized as an important political, social, and economic goal in many countries around the world. At a country level, there is evidence that gender equality may have an important influence on health. Historically gender equality has mainly been measured to allow for between-country, rather than within-country comparisons; and the association between gender equality and health outcomes within countries has been under-researched. This article thus aimed to systematically review within-country indicators of gender equality in public health studies and assess the extent to which these are related to health outcomes. Materials and Methods: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach with two independent reviewers. Results: Data from the eight included studies revealed that there was heterogeneity in the way gender equality has been measured as a multidimensional construct. Associations between gender equality and a number of different health outcomes were apparent, including mortality, mental health, morbidity, alcohol consumption, and intimate partner violence, with gender equality mostly associated with better health outcomes. Conclusions: Further investigation into the effects of gender equality on health outcomes, including a clear conceptualization of terms, is critical for the development of policies and programs regarding gender equality.

Gendered experiences of unemployment, suicide and self-harm: a population-level record linkage study

BACKGROUND

Unemployment and being not in the labour force (NILF) are risk factors for suicide, but their association with self-harm is unclear, and there is continuing debate about the role of confounding by prior mental health conditions. We examine associations between employment status and self-harm and suicide in a prospective cohort, taking into account prior mental-health-related factors.

METHODS

We used linked data from the New Zealand Integrated Data Infrastructure. The outcomes were chosen to be hospital presentation for self-harm and death by suicide. The exposure was employment status, defined as employed, unemployed, or NILF, measured at the 2013 Census. Confounders included demographic factors and mental health history (use of antidepressant medication, use of mental health services, and prior self-harm). Logistic regression was used to model effects. Analyses were stratified by gender.

RESULTS

For males, unemployment was associated with an increased risk of suicide [odds ratio (OR): 1.48, 95% confidence interval (CI): 1.20-1.84] and self-harm (OR: 1.55, 95% CI: 1.45-1.68) after full adjustment for confounders. NILF was associated with an increased risk of self-harm (OR: 1.43, 95% CI: 1.32-1.55), but less of an association was seen with suicide (OR: 1.19, 95% CI: 0.94-1.49). For females, unemployment was associated with an increased risk of suicide (OR: 1.30, 95% CI: 0.93-1.80) and of self-harm (OR: 1.52, 95% CI: 1.43-1.62), and NILF was associated with a similar increase in risk for suicide (OR: 1.31, 95% CI: 0.98-1.75) and self-harm (OR: 1.32, 95% CI: 1.26-1.40).

DISCUSSION

Exclusion from employment is associated with a considerably heightened risk of suicide and self-harm for both men and women, even among those without prior mental health problems.

Educational and Employment Outcomes among Young Australians with a History of Depressive Symptoms: A Prospective Cohort Study

The aim of this study was to investigate whether depressive symptoms reported during adolescence are associated with subsequent educational and employment outcomes, including whether experiences of depressive symptoms in adolescence are associated with higher exposures to adverse psychosocial job stressors among those who were employed in emerging adulthood. We used data from the Victorian arm of the International Youth Development Study (IYDS). Multiple logistic regression analyses were used to model the association of depressive symptoms reported in 2002 (wave one) and/or 2003 (wave two) and self-reported completion of compulsory secondary schooling, employment status, and exposure to a number of psychosocial job stressors roughly a decade later (i.e., at wave three in 2014). In fully adjusted models, reporting high depressive symptoms at waves one or two (odds ratio (OR) 0.71, 95% confidence interval (CI) 0.55 to 0.92), as well as at both waves (OR 0.55, 95% CI 0.41 to 0.75) were associated with a reduced likelihood of completing secondary schooling by wave three. High depressive symptoms reported at multiple waves were also associated with a reduced likelihood of employment (OR 0.49, 95% CI 0.36 to 0.66). Amongst those employed at wave three (n = 2091; 72.5%), adolescent depressive symptoms were associated only with workplace incivility. Psychosocial job stressor exposures should be considered in the design and selection of jobs for young workers with a history of depressive symptoms in order to increase employment participation and sustainability for young people experiencing symptoms of depression.

Physicians' attitudes to disability pension - impact of diagnosis: an experimental study

BACKGROUND

The purpose of this study is to increase understanding of physicians' attitudes towards disability pension applicants, and the impact of diagnosis. We hypothesize that physicians are more likely to think that patients with physical illnesses should get a disability pension than those with mental illness or alcohol dependence. Disability pension is an important source of income for those unable to work because of a disability and type of diagnosis should not impact accessing these benefits.

METHODS

We conducted an experiment with a 2 by 3 factorial structure in Sweden. Each physician was randomly assigned one of six patient vignettes, with the same background description but with a different diagnosis. Each vignette had a diagnosis of either depression, alcohol dependence or low back pain, and was about a man or a woman. Logistic regression was used to examine the odds of a physician reporting that a patient should get a disability pension. Effects are reported in terms of odds ratios (ORs).

RESULTS

1414 Swedish registered physicians in psychiatry or general practice (24% response rate) completed the survey. Physicians assigned the alcohol dependent vignette had OR 0.45 (95% CI: 0.34 to 0.60) for perceiving that a patient should get a disability pension compared to physicians assigned the low back pain vignette. Physicians assigned the depression vignette had OR 1.89 (95% CI: 1.42 to 2.50) for perceiving that a patient should get a disability pension compared to physicians assigned the low back pain vignette.

CONCLUSION

The patient diagnosis was associated with the physicians' response regarding if the patient should get a disability pension. A physician's perception is likely to impact a patient's access to disability pension.

How do employment conditions and psychosocial workplace exposures impact the mental health of young workers? A systematic review

PURPOSE

To assess the quality of the research about how employment conditions and psychosocial workplace exposures impact the mental health of young workers, and to summarize the available evidence.

METHODS

We undertook a systematic search of three databases using a tiered search strategy. Studies were included if they: (a) assessed employment conditions such as working hours, precarious employment, contract type, insecurity, and flexible work, or psychosocial workplace exposures such as violence, harassment and bullying, social support, job demand and control, effort-reward imbalance, and organizational justice; (b) included a validated mental health measure; and (c) presented results specific to young people aged ≤ 30 years or were stratified by age group to provide an estimate for young people aged ≤ 30 years. The quality of included studies was assessed using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool.

RESULTS

Nine studies were included in the review. Four were related to employment conditions, capturing contract type and working hours. Five studies captured concepts relevant to psychosocial workplace exposures including workplace sexual harassment, psychosocial job quality, work stressors, and job control. The quality of the included studies was generally low, with six of the nine at serious risk of bias. Three studies at moderate risk of bias were included in the qualitative synthesis, and results of these showed contemporaneous exposure to sexual harassment and poor psychosocial job quality was associated with poorer mental health outcomes among young workers. Longitudinal evidence showed that exposure to low job control was associated with incident depression diagnosis among young workers.

CONCLUSIONS

The findings of this review illustrate that even better studies are at moderate risk of bias. Addressing issues related to confounding, selection of participants, measurement of exposures and outcomes, and missing data will improve the quality of future research in this area and lead to a clearer understanding of how employment conditions and psychosocial workplace exposures impact the mental health of young people. Generating high-quality evidence is particularly critical given the disproportionate impact of COVID-19 on young people's employment. In preparing for a post-pandemic world where poor-quality employment conditions and exposure to psychosocial workplace exposures may become more prevalent, rigorous research must exist to inform policy to protect the mental health of young workers.

Psychosocial Work Factors of the Job Strain Model and All-Cause Mortality: The STRESSJEM Prospective Cohort Study

OBJECTIVE

The objectives were to examine the prospective associations between psychosocial work factors of the job strain model and all-cause mortality in a national representative cohort of French employees using various measures of time-varying exposure.

METHODS

The study was based on a sample of 798,547 men and 697,785 women for which data on job history from 1976 to 2002 were linked to mortality data from the national death registry. Psychosocial work factors from the validated job strain model questionnaire were imputed using a job-exposure matrix. Three time-varying measures of exposure were explored: current, cumulative, and recency-weighted cumulative exposure. Cox proportional hazards models were performed to study the associations between psychosocial work factors and mortality.

RESULTS

Within the 1976-2002 period, 88,521 deaths occurred among men and 28,921 among women. Low decision latitude, low social support, job strain, isostrain, high strain, and passive job were found to be risk factors for mortality. The model using current exposure was the best relative-quality model. The associations of current exposure to job strain and mortality were found to have hazard ratios of 1.30 (95% confidence interval [CI] = 1.24-1.36) among men and 1.15 (95% CI = 1.06-1.25) among women. The population fractions of mortality attributable to job strain were 5.64% (95% CI = 4.56%-6.71%) among men and 4.13% (95% CI = 1.69%-6.71%) among women.

CONCLUSIONS

This study supports the role of the psychosocial work factors of the job strain model on all-cause mortality. Preventive intervention to improve the psychosocial work environment may help to prevent mortality in working populations.

Socioeconomic Disadvantage, Mental Health and Substance Use in Young Men in Emerging Adulthood

Emerging adulthood is a neglected phase of the life course in health research. Health problems and risk behaviors at this time of life can have long-term consequences for health. The 2016 Lancet Commission on Adolescent Health and Wellbeing reported that the influence of socioeconomic factors was under-researched among adolescents and young adults. Moreover, the influence of socioeconomic factors on health has been little researched specifically in emerging adult men. We aimed to investigate associations between socioeconomic disadvantage and mental health, suicidal behavior, and substance use in young adult Australian men. Logistic regression was used to examine the association between Year 12 (high school) completion and area disadvantage on mental health, suicidal behavior, and substance use in 2,281 young men age 18-25 participating in the Australian Longitudinal Study on Male Health (Ten to Men). In unadjusted analysis both Year 12 non-completion and area disadvantage were associated with multiple adverse outcomes. In adjusted analysis Year 12 non-completion, but not area disadvantage, was associated with poorer mental health, increased odds of suicidal behavior, and substance use. Retaining young men in high school and developing health-promotion strategies targeted at those who do exit education early could both improve young men's mental health and reduce suicidal behavior and substance use in emerging adulthood.

Does disability modify the relationship between labour force status and psychological distress among young people?

OBJECTIVE

To examine the association between labour force status, including young people who were unemployed and having problems looking for work, and psychological distress one year later. We then assessed whether this association is modified by disability status.

METHODS

We used three waves of cohort data from the Longitudinal Surveys of Australian Youth. We fitted logistic regression models to account for confounders of the relationship between labour force status (employed, not in the labour force, unemployed and having problems looking for work) at age 21 years and psychological distress at age 22 years. We then estimated whether this association was modified by disability status at age 21 years.

RESULTS

Being unemployed and having problems looking for work at age 21 years was associated with odds of psychological distress that were 2.48 (95% CI 1.95 to 3.14) times higher than employment. There was little evidence for additive effect measure modification of this association by disability status (2.52, 95% CI -1.21 to 6.25).

CONCLUSIONS

Young people who were unemployed and having problems looking for work had increased odds of poor mental health. Interventions should focus on addressing the difficulties young people report when looking for work, with a particular focus on supporting those young people facing additional barriers to employment such as young people with disabilities.

Breadwinners and Losers: Does the Mental Health of Mothers, Fathers, and Children Vary by Household Employment Arrangements? Evidence From 7 Waves of Data From the Longitudinal Study of Australian Children

In Australia, as in many industrialized countries, the past 50 years have been marked by increasing female labor-force participation. It is popularly speculated that this might impose a mental-health burden on women and their children. This analysis aimed to examine the associations between household labor-force participation (household employment configuration) and the mental health of parents and children. Seven waves of data from the Longitudinal Study of Australian Children were used, comprising 2004-2016, with children aged 4-17 years). Mental health outcome measures were the Strengths and Difficulties Questionnaire (children/adolescents) and 6-item Kessler Psychological Distress Scale (parents). A 5-category measure of household employment configuration was derived from parental reports: both parents full-time, male-breadwinner, female-breadwinner, shared-part-time employment (both part-time) and father full-time/mother part-time (1.5-earner). Fixed-effects regression models were used to compare within-person effects, controlling for time-varying confounders. For men, the male-breadwinner configuration was associated with poorer mental health compared with the 1.5-earner configuration (β = 0.21, 95% confidence interval: 0.05, 0.36). No evidence of association was observed for either women or children. This counters prevailing social attitudes, suggesting that neither children nor women are adversely affected by household employment configuration, nor are they disadvantaged by the extent of this labor-force participation. Men's mental health appears to be poorer when they are the sole household breadwinner.

Associations between gender equality and health: a systematic review

This systematic review sought to evaluate the impact of gender equality on the health of both women and men in high-income countries. A range of health outcomes arose across the 48 studies included. Gender equality was measured in various ways, including employment characteristics, political representation, access to services, and with standard indicators (such as the Global Gender Gap Index and the Gender Empowerment Measure). The effects of gender equality varied depending on the health outcome examined, and the context in which gender equality was examined (i.e. employment or domestic domain). Overall, evidence suggests that greater gender equality has a mostly positive effect on the health of males and females. We found utility in the convergence model, which postulates that gender equality will be associated with a convergence in the health outcomes of men and women, but unless there is encouragement and support for men to assume more non-traditional roles, further health gains will be stymied.

The effect of gender on mental health service use: an examination of mediation through material, social and health-related pathways

PURPOSE

We aimed to understand how much of the gender difference in mental health service use could be due to the joint mediation of employment, behavioural and material factors, social support and mental health need.

METHODS

We used data from employed individuals aged 18-65 years who participated in the 2015-2017 waves of the Household, Income and Labour Dynamics in Australia survey. The exposure (male, female) and confounders were measured in 2015, mediators in 2016 and the outcome-whether a person had seen a mental health professional in the previous year-was measured in 2017. We estimated natural mediation effects using weighted counterfactual predictions from a logistic regression model.

RESULTS

Men were less likely to see a mental health care provider than women. The total causal effect on the risk difference scale was  - 0.045 (95% CI  - 0.056,  - 0,034). The counterfactual of men taking the mediator values of women explained 28% (95% CI 1.7%, 54%) of the total effect, with the natural direct effect estimated to represent an absolute risk difference of  - 0.033 (95% CI  - 0.048,  - 0.018) and the natural indirect effect  - 0.012 (95% CI  - 0.022,  - 0.0027).

CONCLUSION

Gendered differences in the use of mental health services could be reduced by addressing inequalities in health, employment, material and behavioural factors, and social support.

Gendered working environments as a determinant of mental health inequalities: a systematic review of 27 studies

BACKGROUND

'Gendered working environments' describes the ways in which (1) differential selection into work, (2) variations in employment arrangements and working hours, (3) differences in psychosocial exposures and (4) differential selection out of work may produce varied mental health outcomes for men and women. The aim of this study was to conduct a systematic review to understand gender differences in mental health outcomes in relation to the components of gendered working environments.

METHODS

The review followed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search approach and focused on studies published in 2008-2018. The protocol for the review was prospectively registered with PROSPERO (CRD42019124066).

FINDINGS

Across the 27 cohort studies included in the review, we found that (1) there was inconclusive evidence on the effect of occupational gender composition on the mental health of men and women, (2) women's mental health was more likely to be affected by long working hours than men's; however, precarious employment was more likely to be negatively associated with men's mental health, (3) exposure to traditional constructs of psychosocial job stressors negatively affected the mental health of both women and men, and (4) unemployment and retirement are associated with poorer mental health in both genders.

INTERPRETATION

The findings from this review indicate that gendered working environments may affect the mental health of both men and women, but the association is dependent on the specific exposure examined. There is still much to be understood about gendered working environments, and future research into work and health should be considered with a gender lens.

The impact of the disability support pension on mental health: evidence from 14 years of an Australian cohort

OBJECTIVE

To assess the effect of the Australian Disability Support Pension (DSP) on the symptomology of depression and anxiety over and above the effects of reporting a disability itself.

METHODS

We used the Household Income Labour Dynamics in Australia (HILDA) survey from 2004 to 2017. We used fixed effects regression to understand mental health differences (using the Mental Health Inventory-5 [MHI-5]) when a person reported: i) a disability; or ii) a disability and receiving the DSP) compared to when they reported no disability. The models controlled for time-varying changes in the severity of the disability and other time-related confounders.

RESULTS

There was a 2.97-point decline (95%CI -3.26 to -2.68) in the MHI-5 when a person reported a disability compared to waves in which they reported no disability and 4.48-point decline (95%CI -5.75 to -3.22) when a person reported both a disability and being on the DSP compared to waves in which they reported neither.

CONCLUSIONS

Results suggest that accessing and being in receipt of the DSP can impact the mental health of people with disabilities. Implications for public health: Government income support policies should address the unintended adverse consequences in already vulnerable populations.
