Unpaid overtime and mental health in the Canadian working population.

BACKGROUND: Unpaid overtime-describing a situation where extra hours are worked but not paid for-is a common feature of the labor market that, together with other forms of wage theft, costs workers billions of dollars annually. In this study, we examine the association between unpaid overtime and mental health in the Canadian working population. We also assess the relative strength of that association by comparing it against those of other broadly recognized work stressors. METHODS: Data were drawn from a survey administered to a heterogeneous sample of workers in Canada (n = 3691). Generalized linear models quantified associations between unpaid overtime, stress, and burnout, distinguishing between moderate (1-5) and excessive (6 or more) hours of unpaid overtime. RESULTS: Unpaid overtime was associated with higher levels of stress and burnout. Relative to those working no unpaid overtime, men working excessive unpaid overtime were 85% more likely to report stress (prevalence ratios [PR]: 1.85, 95% confidence interval [CI]: 1.26-2.72) and 84% more likely to report burnout (PR: 1.84, 95% CI: 1.34-2.54), while women working excessive unpaid overtime were 90% more likely to report stress (PR: 1.90, 95% CI: 1.32-2.75) and 52% more likely to report burnout (PR: 1.52; 95% CI: 1.12-2.06). The association of excessive unpaid overtime with mental health was comparable in magnitude to that of shift work and low job control. CONCLUSIONS: Unpaid overtime may present a significant challenge to the mental health of working people, highlighting the potential role of wage theft as a neglected occupational health hazard.

Variation in occupational exposure risk for COVID-19 workers' compensation claims across pandemic waves in Ontario.

OBJECTIVES: To understand rates of work-related COVID-19 (WR-C19) infection by occupational exposures across waves of the COVID-19 pandemic in Ontario, Canada. METHODS: We combined workers' compensation claims for COVID-19 with data from Statistics Canada's Labour Force Survey, to estimate rates of WR-C19 among workers spending the majority of their working time at the workplace between 1 April 2020 and 30 April 2022. Occupational exposures, imputed using a job exposure matrix, were whether the occupation was public facing, proximity to others at work, location of work and a summary measure of low, medium and high occupational exposure. Negative binomial regression models examined the relationship between occupational exposures and risk of WR-C19, adjusting for covariates. RESULTS: Trends in rates of WR-C19 differed from overall COVID-19 cases among the working-aged population. All occupational exposures were associated with increased risk of WR-C19, with risk ratios for medium and high summary exposures being 1.30 (95% CI 1.09 to 1.55) and 2.46 (95% CI 2.10 to 2.88), respectively, in fully adjusted models. The magnitude of associations between occupational exposures and risk of WR-C19 differed across waves of the pandemic, being weakest for most exposures in period March 2021 to June 2021, and highest at the start of the pandemic and during the Omicron wave (December 2021 to April 2022). CONCLUSIONS: Occupational exposures were consistently associated with increased risk of WR-C19, although the magnitude of this relationship differed across pandemic waves in Ontario. Preparation for future pandemics should consider more accurate reporting of WR-C19 infections and the potential dynamic nature of occupational exposures.

Job quality and precarious employment among lesbian, gay, and bisexual workers: A national study.

Background: Employment outcomes among sexual minority (i.e., lesbian, gay, bisexual) workers are poorly understood, and previous research on this topic has focused almost exclusively on inequities in earnings, neglecting other important dimensions of job quality. We address this gap by describing and comparing the job quality of straight and sexual minority workers in Canada. Methods: Data are from the 2016 General Social Survey: Canadians at Work and Home, the only national survey providing both a measure of sexual orientation and a multidimensional view of job quality in Canada. We identified 25 unique job quality indicators (e.g., temporary employment; job insecurity; health benefits; low income; job satisfaction; job control; discrimination). Latent class cluster analysis was used to establish a typology of job quality describing standard, flexible, and precarious employment types. We used multivariable regression methods to examine the association between sexual orientation and job quality. Results: Sexual minorities reported lower job quality than their straight counterparts along many dimensions, with bisexual people reporting the lowest job quality. While inequities were generally observed among both sexual minority men and women, they sometimes differed in magnitude by gender. The prevalence of precarious employment was nearly three times higher among lesbian, gay, and bisexual workers (PR: 2.94, CI: 1.89-4.58 among all sexual minorities; PR: 3.04, CI: 1.71-5.43 among gay/lesbian workers; and PR: 2.81, CI: 1.45-5.47 among bisexual workers) compared to their straight counterparts. Conclusion: Inequities in job quality among sexual minorities persist despite comprehensive human rights protections in Canada. These inequities are pervasive, extending well beyond conventional indicators such as dollars earned and hours worked. Multi-pronged interventions are needed that move beyond simply ensuring that sexual minority workers are employed. Sexual minority workers deserve access to secure, well-paid work with benefits where they can foster connection and be free from discrimination.

Identifying the sociodemographic and work-related factors related to workers' daily physical activity using a decision tree approach.

BACKGROUND: The social and behavioural factors related to physical activity among adults are well known. Despite the overlapping nature of these factors, few studies have examined how multiple predictors of physical activity interact. This study aimed to identify the relative importance of multiple interacting sociodemographic and work-related factors associated with the daily physical activity patterns of a population-based sample of workers. METHODS: Sociodemographic, work, screen time, and health variables were obtained from five, repeated cross-sectional cohorts of workers from the Canadian Health Measures Survey (2007 to 2017). Classification and Regression Tree (CART) modelling was used to identify the discriminators associated with six daily physical activity patterns. The performance of the CART approach was compared to a stepwise multinomial logistic regression model. RESULTS: Among the 8,909 workers analysed, the most important CART discriminators of daily physical activity patterns were age, job skill, and physical strength requirements of the job. Other important factors included participants' sex, educational attainment, fruit/vegetable intake, industry, work hours, marital status, having a child living at home, computer time, and household income. The CART tree had moderate classification accuracy and performed marginally better than the stepwise multinomial logistic regression model. CONCLUSION: Age and work-related factors-particularly job skill, and physical strength requirements at work-appeared as the most important factors related to physical activity attainment, and differed based on sex, work hours, and industry. Delineating the hierarchy of factors associated with daily physical activity may assist in targeting preventive strategies aimed at promoting physical activity in workers.

Inflation hardship, gender, and mental health.

Inflation hit a 40 year high in the United States in 2022, yet the impact of inflation related hardships on distress is poorly understood, particularly the impact on women, whose income is already more limited. Using data from the US Household Pulse Survey (September-November 2022), we test whether exposure to inflation hardships is associated with greater distress and whether this association is moderated by gender (n = 119,531). We draw on a list of eighteen inflation related hardships (e.g., purchasing less food, working additional jobs, delaying medical treatment) to construct an ordinal measure of exposure to inflation hardship ranging from "no inflation hardship" to "five or more inflation hardships." We observe that an increasing number of inflation hardships is associated with higher levels of distress. We find no evidence of gender differences in the magnitude of that association at lower levels of inflation hardship (four inflation hardships or less). However, our findings suggest that exposure to five or more inflation hardships is more strongly associated with distress among men compared to women. The current study provides new insights into the cumulative burden of inflation hardships on mental health and the role that gender plays in this association.

Artificial intelligence and the work-health interface: A research agenda for a technologically transforming world of work.

The labor market is undergoing a rapid artificial intelligence (AI) revolution. There is currently limited empirical scholarship that focuses on how AI adoption affects employment opportunities and work environments in ways that shape worker health, safety, well-being and equity. In this article, we present an agenda to guide research examining the implications of AI on the intersection between work and health. To build the agenda, a full day meeting was organized and attended by 50 participants including researchers from diverse disciplines and applied stakeholders. Facilitated meeting discussions aimed to set research priorities related to workplace AI applications and its impact on the health of workers, including critical research questions, methodological approaches, data needs, and resource requirements. Discussions also aimed to identify groups of workers and working contexts that may benefit from AI adoption as well as those that may be disadvantaged by AI. Discussions were synthesized into four research agenda areas: (1) examining the impact of stronger AI on human workers; (2) advancing responsible and healthy AI; (3) informing AI policy for worker health, safety, well-being, and equitable employment; and (4) understanding and addressing worker and employer knowledge needs regarding AI applications. The agenda provides a roadmap for researchers to build a critical evidence base on the impact of AI on workers and workplaces, and will ensure that worker health, safety, well-being, and equity are at the forefront of workplace AI system design and adoption.

Racial and Ethnic Inequities in the Return-to-Work of Workers Experiencing Injury or Illness: A Systematic Review.

PURPOSE: Non-White workers face more frequent, severe, and disabling occupational and non-occupational injuries and illnesses when compared to White workers. It is unclear whether the return-to-work (RTW) process following injury or illness differs according to race or ethnicity. OBJECTIVE: To determine racial and ethnic differences in the RTW process of workers with an occupational or non-occupational injury or illness. METHODS: A systematic review was conducted. Eight academic databases - Medline, Embase, PsycINFO, CINAHL, Sociological Abstracts, ASSIA, ABI Inform, and Econ lit - were searched. Titles/abstracts and full texts of articles were reviewed for eligibility; relevant articles were appraised for methodological quality. A best evidence synthesis was applied to determine key findings and generate recommendations based on an assessment of the quality, quantity, and consistency of evidence. RESULTS: 15,289 articles were identified from which 19 studies met eligibility criteria and were appraised as medium-to-high methodological quality. Fifteen studies focused on workers with a non-occupational injury or illness and only four focused on workers with an occupational injury or illness. There was strong evidence indicating that non-White and racial/ethnic minority workers were less likely to RTW following a non-occupational injury or illness when compared to White or racial/ethnic majority workers. CONCLUSIONS: Policy and programmatic attention should be directed towards addressing racism and discrimination faced by non-White and racial/ethnic minority workers in the RTW process. Our research also underscores the importance of enhancing the measurement and examination of race and ethnicity in the field of work disability management.

The Employment Quality of Persons with Disabilities: Findings from a National Survey.

PURPOSE: Labour market integration is a widely accepted strategy for promoting the social and economic inclusion of persons with disabilities. But what kinds of jobs do persons with disabilities obtain following their integration into the labour market? In this study, we use a novel survey of workers to describe and compare the employment quality of persons with and without disabilities in Canada. METHODS: We administered an online, cross-sectional survey to a heterogeneous sample of workers in Canada (n = 2,794). We collected data on sixteen different employment conditions (e.g., temporary contract, job security, flexible work schedule, job lock, skill match, training opportunities, and union membership). We used latent class cluster analysis to construct a novel typology of employment quality describing four distinct 'types' of employment: standard, portfolio, instrumental, and precarious. We examined associations between disability status, disability type, and employment quality. RESULTS: Persons with disabilities reported consistently lower employment quality than their counterparts without disabilities. Persons with disabilities were nearly twice as likely to report low-quality employment in the form of either instrumental (i.e., secure but trapped) or precarious (i.e., insecure and unrewarding) employment. This gap in employment quality was particularly pronounced for those who reported living with both a physical and mental/cognitive condition. CONCLUSION: There are widespread inequalities in the employment quality of persons with and without disabilities in Canada. Policies and programs aiming to improve the labour market situation of persons with disabilities should emphasize the importance of high-quality employment as a key facet of social and economic inclusion.

How Does Job Insecurity and Workplace Activity Limitations Relate to Rheumatic Disease Symptom Trajectories in Young Adulthood? A Longitudinal Study.

OBJECTIVE: Workplace and labor market conditions are associated with the health of the working population. A longitudinal study was conducted among young adults with rheumatic disease to examine workplace activity limitations and job insecurity and their relationship with disease symptom trajectories. METHODS: Three online surveys were administered to young adults with rheumatic disease over 27 months. Self-reported data on pain, fatigue, and disease activity were collected. Workplace activity limitations and job insecurity were measured. Group-based discrete mixture models determined pain, fatigue, and disease activity trajectory groups. Robust Poisson regression models were fitted to examine the relationship among workplace activity limitations, job insecurity, and trajectory group membership. RESULTS: In total, 124 participants (mean ± SD age 29 ± 4.5 years) with rheumatic disease were recruited. At baseline, participants reported considerable workplace activity limitations (10.35 ± 5.8), and 36% of participants indicated experiencing job insecurity. We identified 2 latent rheumatic disease symptom trajectory groups. The first group had high persistent pain, fatigue, or disease activity; the second group had low persistent disease symptoms over time. Greater workplace activity limitations were associated with an increased relative risk (RR) of being in the high persistent severe pain (RR 1.02 [95% confidence interval (95% CI) 1.01, 1.03]), fatigue (RR 1.02 [95% CI 1.01, 1.03]), and disease activity trajectory groups (RR 1.02 [95% CI 1.01, 1.03]). Job insecurity was associated with an increased RR of membership in the high persistent pain (RR 1.14 [95% CI 1.04, 1.25]) and disease activity trajectory groups (RR 1.11 [95% CI 1.00, 1.22]). CONCLUSION: Workplace activity limitations and job insecurity represent working conditions that are associated with the health of young adults with rheumatic disease and should be examined as potential targets for intervention.

Longitudinal Reciprocal Relationships Between the Psychosocial Work Environment and Burnout.

OBJECTIVE: To examine longitudinal reciprocal relationships between the psychosocial work environment and burnout. METHODS: We used two-wave cross-lagged panel models to estimate associations between a wide range of psychosocial work factors (ie, job demands, job control, job insecurity, coworker support, supervisor support, and organizational justice) and burnout in a broadly representative sample of the general working population in Canada (n = 453). RESULTS: Bidirectional associations between the psychosocial work environment and burnout were observed. Results supported the causal predominance of psychosocial work factors over burnout. Higher job demands, lower job control, higher job insecurity, and lower organizational justice predicted burnout over time. Burnout only predicted lower supervisor support over time. CONCLUSIONS: Our findings suggest that stress at work is better understood as a cause rather than a consequence of burnout in the general working population.

Understanding income-related differences in distribution of child growth, behaviour and development using a cross-sectional sample of a clinical cohort study.

OBJECTIVES: Children from low-income households are at an increased risk of social, behavioural and physical health problems. Prior studies have generally relied on dichotomous outcome measures. However, inequities may exist along the range of outcome distribution. Our objective was to examine differences in distribution of three child health outcomes by income categories (high vs low): body mass index (BMI), behaviour difficulties and development. DESIGN AND SETTING: This was a cross-sectional study using data from a primary care-based research network with sites in three Canadian cities, and 15 practices enrolling participants. PARTICIPANTS, INDEPENDENT VARIABLE AND OUTCOMES: The independent variable was annual household income, dichotomised at the median income for Toronto (<$C80 000 or ≥$C80 000). Outcomes were: (1) growth (BMI z-score (zBMI) at 5 years, 1628 participants); (2) behaviour (Strengths and Difficulties Questionnaire (SDQ) at 3-5 years, 649 participants); (3) development (Infant Toddler Checklist (ITC) at 18 months, 1405 participants). We used distributional decomposition to compare distributions of these outcomes for each income group, and then to construct a counterfactual distribution that describes the hypothetical distribution of the low-income group with the predictor profile of the higher-income group. RESULTS: We included data from 1628 (zBMI), 649 (SDQ) and 1405 (ITC) children. Children with lower family income had a higher risk distribution for all outcomes. For all outcomes, thecounterfactual distribution, which represented the distribution of children with lower-income who were assigned the predictor profile of the higher-income group, was more favourable than their observed distributions. CONCLUSION: Comparing the distributions of child health outcomes and understanding different risk profiles for children from higher-income and lower-income groups can offer a deeper understanding of inequities in child health outcomes. These methods may offer an approach that can be implemented in larger datasets to inform future interventions.

The prevalence and correlates of workplace infection control practices in Canada between July and September 2020.

BACKGROUND: There are important information gaps concerning the prevalence and distribution of infection control practices (ICPs) within workplaces continuing to operate during the COVID-19 pandemic. DATA AND METHODS: To address these gaps, this paper examines the prevalence of workplace ICPs among employed respondents to Statistics Canada's Labour Force Survey in the months of July, August and September 2020 (n = 53,316). The article also seeks to identify sociodemographic, occupational and workplace factors associated with the level and type of workplace ICPs. ICPs included the reorganization of the workplace to allow for physical distancing, increased access to hand sanitizer or handwashing facilities, enhanced cleaning protocols and access to personal protective equipment. Multivariable regression models were used to examine the number of ICPs in place and the absence of specific ICPs. RESULTS: Generally high levels of reported protections among workers (15% of the sample had three ICPs and 72% had four or more ICPs) were observed. However, certain subgroups of workers were less likely to have ICPs in place. These included workers who were male; those with lower levels of education, shorter job tenure, or non-permanent work; and those working in the agricultural, construction, transportation and warehousing, and education industries. INTERPRETATION: In a large sample of Canadian employees, generally high levels of workplace ICPs to reduce the transmission of COVID-19 were observed. Groups with lower levels of ICPs included workers at the start of their employment, workers with low levels of education, and certain industry groups.

Social inequalities in protective behaviour uptake at the start of the COVID-19 pandemic: results from a national survey.

OBJECTIVES: We aimed to assess social patterns of handwashing, social distancing, and working from home at the start of the COVID-19 pandemic in Canada, and determine what proportions of the overall prevalence and social inequalities in handwashing and social distancing are related to inequalities in the opportunity to work from home, to guide pandemic preparedness and response. METHODS: Using cross-sectional data from the Canadian Perspectives Survey Series, collected between March 29 and April 3, 2020, among Canadian adults (N=4455), we assessed prevalence of not working from home, social distancing in public, or practicing frequent handwashing, according to age, sex, marital status, immigration, education, chronic disease presence, and source of COVID-19 information. Multivariate regression, population attributable fraction estimation, and generalized product mediation analysis were applied. RESULTS: Absence of frequent handwashing and distancing was more common among those working outside than within the home (prevalence differences of 7% (95% CI: 4, 10) and 7% (95% CI: 3, 10), respectively). Inequalities in handwashing and distancing were observed across education and immigration status. Over 40% of the prevalence of non-uptake of handwashing and distancing was attributable to populations not being able to work from home. If all worked from home, over 40% (95% CI: 8, 70) of education-based inequalities in handwashing and distancing could be eliminated, but differences by immigration status would likely remain. CONCLUSION: For pandemic response, both workplace safety initiatives and mechanisms to address the inequitable distribution of health risks across socio-economic groups are needed to reduce broader inequalities in transmission risk.

RéSUMé: OBJECTIFS: Nous avons cherché à évaluer les habitudes sociales en matière d'hygiène des mains, de distanciation physique et de travail à domicile au début de la pandémie de la COVID-19 au Canada, et à déterminer quelles proportions de la prévalence globale et des inégalités sociales en matière d'hygiène des mains et de distanciation physique sont liées aux inégalités dans la possibilité de travailler à domicile (le télétravail), afin de guider la préparation et la réponse à la pandémie. MéTHODES: À l'aide des données transversales de la Série d'enquêtes sur les perspectives canadiennes 1, recueillies entre le 29 mars et le 3 avril 2020 auprès d'adultes canadiens (N=4 455), nous avons évalué la prévalence du travail hors du domicile, de la non-distanciation physique en public et de l'absence de lavage fréquent des mains, en fonction de l'âge, du sexe, de l'état civil, de l'immigration, de l'éducation, de la présence de maladies chroniques et de la principale source déclarée d'information sur la COVID-19. Une régression multivariée, une estimation de la fraction attribuable dans la population et une analyse de médiation par produit généralisé ont été appliquées. RéSULTATS: L'absence de lavage fréquent des mains et de distanciation physique étaient déclarées plus fréquemment chez les personnes travaillant à l'extérieur qu'à l'intérieur du domicile (différences de prévalence de 7 % (IC 95 % : 4, 10) et 7 % (IC 95 % : 3, 10), respectivement). Des inégalités en matière de lavage fréquent des mains et de la pratique de distanciation physique ont été observées en fonction du niveau d'éducation et du statut d'immigration. Plus de 40 % de la prévalence de la non-pratique du lavage fréquent des mains et de la distanciation physique était attribuable au fait que les populations ne pouvaient pas travailler à domicile. Si toutes les personnes travaillaient à domicile, plus de 40 % (IC 95 % : 8, 70) des inégalités liées au niveau d'éducation en matière de lavage des mains et distanciation physique pourraient être éliminées, mais les inégalités au niveau du statut d'immigration en matière de ces deux comportements subsisteraient probablement. CONCLUSION: Pour la répondre à la pandémie, il faut à la fois des initiatives de sécurité au travail, ainsi que des mécanismes visant à remédier à la répartition inéquitable des risques sanitaires entre les groupes socio-économiques pour réduire les inégalités plus larges en matière de risque de transmission.

Impacts of the COVID-19 pandemic on health, financial worries, and perceived organizational support among people living with disabilities in Canada.

BACKGROUND: Individuals with physical or mental health disabilities may be particularly vulnerable to the impact of COVID-19 on their health and employment. OBJECTIVES: We examined COVID-19-related concerns for health, finances, and organizational support among workers with no disability, a physical, mental health, or both physical and mental health disability, and factors associated with COVID-19 perceptions. METHODS: An online, cross-sectional survey was administered to a sample of Canadians in the first wave of the COVID-19 pandemic. Questions asked about COVID-19 perceptions, demographics (gender, age, education), work context (e.g., sector, contract work) and employment conditions (e.g., job stress, control, accommodation needs). Descriptive, multivariable, and nested regression analyses examined factors associated with COVID-19 perceptions. RESULTS: A total of 3066 participants completed the survey. Workers with both a physical and mental health disability reported significantly greater health and financial concerns and less organizational support than those with no disability. Workers with a physical disability reported more health concerns and those with a mental health disability reported more financial concerns and less organizational support. Respondents with disabilities also reported significant differences in employment conditions (e.g., more contract work, stress, unmet accommodation needs) than those with no disability. Employment conditions were consistently significant predictors of COVID-19 perceptions and attenuated the significance of disability type in analyses. CONCLUSIONS: Concerns about the impact of COVID-19 on one's health, finances, and organizational support reflected existing disability inequities in employment conditions and highlight the importance of creating more inclusive employment opportunities for people living with physical and mental health disabilities.

Unemployment Insurance and Mortality Among the Long-Term Unemployed: A Population-Based Matched-Cohort Study.

Unemployment insurance is hypothesized to play an important role in mitigating the adverse health consequences of job loss. In this prospective cohort study, we examined whether receiving unemployment benefits is associated with lower mortality among the long-term unemployed. Census records from the 2006 Canadian Census Health and Environment Cohort (n = 2,105,595) were linked to mortality data from 2006-2016. Flexible parametric survival analysis and propensity score matching were used to model time-varying relationships between long-term unemployment (≥20 weeks), unemployment-benefit recipiency, and all-cause mortality. Mortality was consistently lower among unemployed individuals who reported receiving unemployment benefits, relative to matched nonrecipients. For example, mortality at 2 years of follow-up was 18% lower (95% confidence interval (CI): 9, 26) among men receiving benefits and 30% lower (95% CI: 18, 40) among women receiving benefits. After 10 years of follow-up, unemployment-benefit recipiency was associated with 890 (95% CI: 560, 1,230) fewer deaths per 100,000 men and 1,070 (95% CI: 810, 1,320) fewer deaths per 100,000 women. Our findings indicate that receiving unemployment benefits is associated with lower mortality among the long-term unemployed. Expanding access to unemployment insurance may improve population health and reduce health inequalities associated with job loss.

Assessing the Psychosocial Work Environment in Relation to Mental Health: A Comprehensive Approach.

OBJECTIVES: Prevailing job stress models encourage a multidimensional view of the psychosocial work environment and highlight the role that multiple co-occurring stressors play in the aetiology of mental health problems. In this study, we develop a latent typology of psychosocial work environment profiles to describe how a comprehensive array of job stressors are clustered in the Canadian labour market. We also examine the association between these latent psychosocial work environment profiles and several indicators of mental health. METHODS: Data were collected from 6408 workers who completed the Canadian National Psychosocial Work Environment Survey. Psychosocial work exposures were measured using standard items from the Copenhagen Psychosocial Questionnaire. We employed latent profile analyses to identify groups of individuals with similar psychosocial work environment profiles. We used log-linear regression models to examine the association between latent psychosocial work environment profiles and burnout, stress, and cognitive strain. RESULTS: Four distinct groups with highly divergent psychosocial work environment profiles were identified. Adjusting for a range of demographic and socioeconomic factors, latent psychosocial work environment profiles were strongly related to mental health. Individuals who reported exposure to a comprehensive array of psychosocial job stressors (11% prevalence) reported the highest probability of burnout (PR: 7.51, 95% confidence interval [CI]: 5.56-10.15), stress (PR: 8.98, 95% CI: 6.20-13.0), and cognitive strain (PR: 7.29, 95% CI: 5.02-10.60). CONCLUSIONS: Findings suggest that psychosocial work stressors are tightly clustered in the Canadian labour market, and that the clustering of work stressors is strongly associated with adverse mental health outcomes. Future scholarship may benefit from adopting a more comprehensive approach to the assessment of psychosocial job quality as a determinant of health and well-being.

Trends in socioeconomic inequalities in premature and avoidable mortality in Canada, 1991-2016.

BACKGROUND: Recent epidemiologic findings suggest that socioeconomic inequalities in health may be widening over time. We examined trends in socioeconomic inequalities in premature and avoidable mortality in Canada. METHODS: We conducted a population-based repeated cohort study using the 1991, 1996, 2001, 2006 and 2011 Canadian Census Health and Environment Cohorts. We linked individual-level Census records for adults aged 25-74 years to register-based mortality data. We defined premature mortality as death before age 75 years. For each census cohort, we estimated age-standardized rates, risk differences and risk ratios for premature and avoidable mortality by level of household income and education. RESULTS: We identified 16 284 045 Census records. Between 1991 and 2016, premature mortality rates declined in all socioeconomic groups except for women without a high school diploma. Absolute income-related inequalities narrowed among men (from 2478 to 1915 deaths per 100 000) and widened among women (from 1008 to 1085 deaths per 100 000). Absolute education-related inequalities widened among men and women. Relative socioeconomic inequalities in premature mortality widened progressively over the study period. For example, the relative risk of premature mortality associated with the lowest income quintile increased from 2.10 (95% confidence interval [CI] 2.02-2.17) to 2.79 (95% CI 2.66-2.91) among men and from 1.72 (95% CI 1.63- 1.81) to 2.50 (95% CI 2.36-2.64) among women. Similar overall trends were observed for avoidable mortality. INTERPRETATION: Socioeconomically disadvantaged groups have not benefited equally from recent declines in premature and avoidable mortality in Canada. Efforts to reduce socioeconomic inequalities and associated patterns of disadvantage are necessary to prevent this pattern of widening health inequalities from persisting or worsening over time.

The effect of welfare reform on the health of the unemployed: evidence from a natural experiment in Germany.

BACKGROUND: Over the past several decades, governments have enacted far-reaching reforms aimed at reducing the generosity and coverage of welfare benefits. Prior literature suggests that these policy measures may have deleterious effects on the health of populations. In this study, we evaluate the impact of one of the largest welfare reforms in recent history-the 2005 Hartz IV reform in Germany-with a focus on estimating its effect on the health of the unemployed. METHODS: We employed a quasi-experimental difference-in-differences (DID) design using population-based data from the German Socio-Economic Panel Study, covering the period between 1994 and 2016. We applied DID linear probability modelling to examine the association between the Hartz IV reform and poor self-rated health, adjusting for a range of demographic and socioeconomic confounders. RESULTS: The Hartz IV reform was associated with a 3.6 (95% CI 0.9 to 6.2) percentage point increase in the prevalence of poor self-rated health among unemployed persons affected by the reform relative to similar but unaffected controls. This negative association appeared immediately following the implementation of the reform and has persisted over time. CONCLUSION: Governments in numerous European and North American jurisdictions have introduced measures to further diminish the generosity and coverage of welfare benefits. In line with growing concerns over the potential consequences of austerity and associated policy measures, our findings suggest that these reform efforts pose a threat to the health of socioeconomically disadvantaged populations.

Is social assistance boosting the health of the poor? Results from Ontario and three countries.

INTERVENTION: Social assistance programs supplement incomes of the most income-insecure. Because income is a fundamental source of health, income supplementation is expected to result in a boost to health status. As Canada finds itself in the midst of heated debate regarding the structuring (and restructuring) of social assistance programs, there is little evidence available for policymakers about the effectiveness of current social assistance programs in improving the health of the income-insecure. RESEARCH QUESTION: In this paper, we evaluate the health effects of social assistance programs in Ontario, Canada-wide and in peer programs from the United States and the United Kingdom. METHODS: We used nationally representative household panel surveys (e.g., Canadian Survey of Labour and Income Dynamics) which follow individuals over time. Using fixed effects modelling, which controls for time-invariant characteristics of individuals, and further controlling for key time-varying characteristics, we modelled change in health status associated with change in receipt of social assistance in these societies. Health status was measured using self-rated health (fair/poor versus good/very good/excellent). RESULTS: Our results suggest that the health of social assistance recipients was worse (Ontario, Canada, UK) or no different (US) than the health of non-recipients. For example, in Canada, receipt of social assistance was associated with 52.5% higher odds of reporting fair or poor health. CONCLUSION: Social assistance programs in Canada and peer countries are currently inadequate for improving the health of the income-insecure. This is likely due to insufficient benefits, exposure to precarious job conditions, or selection factors.
