Mid-life psychosocial work environment as a predictor of work exit by age 50

Gender- and age-specific associations between psychosocial work conditions and perceived work sustainability in the general working population in Taiwan

OBJECTIVES

One aspect of work sustainability pertains to workers' intention to remain in their current job until reaching retirement age. Various adverse working conditions are expected to diminish work sustainability among different social groups. This study aims to examine these associations across gender and age groups.

METHODS

The study participants were 19,152 economically-active adults in a national survey conducted in Taiwan. Information concerning psychosocial working conditions were obtained through interviews, using the Job Content Questionnaire. Work sustainability was evaluated by one question that asked whether the participants felt they would be able to do their current job until the age of 60. The association between psychosocial work conditions and work sustainability was examined by logistic regression analysis. We further performed stratified analysis to explore age and gender-specific associations.

RESULTS

We observed that 14.2% and 17.1% of male and female workers reported low work sustainability. Workers in the electronics industries and female workers in the healthcare and education sectors reported low work sustainability. Gender-specific analyses showed that low job control among men and shift work among women were significantly associated with low work sustainability. Age-specific analyses indicated that having poor health, shift work, and long working hours in younger workers, and having low job control in older workers were associated with low work sustainability.

CONCLUSION

To retain older workers in the labor market, policies should aim at the improvement of psychosocial work conditions, and gender- and age-specific issues should be taken into consideration.

Do influence at work and possibilities for development mitigate the impact of job demands for workers with and without depression

OBJECTIVE

Jobs characterized by low job demands and high job resources are associated with better work outcomes, yet it remains unclear whether this is the case for workers with depression. This study examined whether depression moderates the relationship between job demands, job resources, and maintaining employment.

METHODS

Data from the longitudinal population-based Lifelines cohort study were matched with register data on employment from Statistics Netherlands (N=55 950). Job demands included quantitative demands and work pace; job resources included influence at work and possibilities for development. The two-way interaction between job demands and depression and the three-way interaction between job demands, job resources and depression were examined in a zero-inflated Poisson regression model with path 1, including a binary employment outcome, and path 2, a count variable including months out of employment.

RESULTS

The interaction effect of job demands and depression on being employed was significant [b=-0.22, 95% confidence interval (CI) -0.44‒0.01]. Workers without depression were more likely to be employed whereas workers with depression were less likely to be employed if they had high job demands. The three-way interaction between job demands, job resources, and depression was significant for months out of employment (b=0.15, 95% CI 0.01‒0.29), indicating that workers with depression had more months out of employment when reporting high job demands and high job resources compared to workers without depression. Discussion Although increasing influence at work and possibilities for development to prevent negative work outcomes may be beneficial for workers without depression, this approach might be limited for workers with depression.

Sustainable Working Life Patterns in a Swedish Twin Cohort: Age-Related Sequences of Sickness Absence, Disability Pension, Unemployment, and Premature Death during Working Life

We aimed to investigate sustainable working life via age-related sequences of sickness absence (SA), disability pension (DP), unemployment (UE), premature death, and the influence of individual characteristics, accounting for familial confounding. The sample included monozygotic (MZ) and dizygotic (DZ) same-sexed twin pairs with register data (n = 47,450) that were followed for 10 years in four age cohorts: 26-35 (n = 9892), 36-45 (n = 10,620), 46-55 (n = 12,964) and 56-65 (n = 13,974). A sequence analysis was done in a 7-element state space: 1. "Sustainable working life": SA/DP 0-30 days and UE 0-90 days; 2. "Unemployment >90 days": SA/DP 0-30 days and UE > 90 days; 3. "Moderate SA/DP": SA/DP 30-180 days; 4. "Almost full year of SA/DP": SA/DP 180-365 days; 5. "Full year of SA/DP": SA/DP ≥ 365 days; 6. Death; 7. Old-age pension. The largest cluster had a sustainable working life and never experienced states 2-6 (34-59%). Higher education and being married predicted a lower likelihood of experiencing states 2-6. The MZ twin pairs (vs. DZ) were more often in the same cluster suggesting the role of genetic factors. To conclude, the sustainable working life was the largest cluster group. Few individuals had prolonged periods of interruptions of sustainable working life meriting actions, especially in early adulthood for interventions to support workability.

Do chronic diseases moderate the association between psychosocial working conditions and work exit? Longitudinal results from 55 950 Dutch workers

BACKGROUND

This study aims to examine whether the presence of chronic diseases or multimorbidity moderates the associations between psychosocial working conditions and work exit through unemployment, work disability or early retirement.

METHODS

Data from Lifelines (n=55 950), a prospective population-based cohort study, were enriched with monthly information on employment status from Statistics Netherlands. Working conditions were measured with the Copenhagen Psychosocial Questionnaire. Work exit was defined as unemployment, work disability and early retirement. Participants were classified as having no chronic disease, one chronic disease or multimorbidity. Cause-specific Cox proportional hazard regression models, adjusted for age, gender, education and partnership status, were used to analyse associations between working conditions and work exit. Interaction terms were used to examine moderation by chronic disease status.

RESULTS

Higher social support decreased the risk for unemployment, work disability and early retirement. Higher meaning of work decreased the risk of unemployment, and more possibilities for development decreased the risk for work disability. Chronic disease status did generally not moderate associations between working conditions and work exit. Only among workers without a chronic disease, more possibilities for development was associated with a lower risk for unemployment (HR: 0.89; 95% CI: 0.85 to 0.94).

CONCLUSION

While efforts to retain workers with chronic diseases in the labour market should continue, favourable psychosocial working conditions are important for all workers.

Work environment and labour market participation in early adulthood

BACKGROUND

Investigating whether a poor physical or psychosocial work environment is associated with low labour market participation in early adulthood is important to avoid negative health-related consequences and to improve job prospects.

AIMS

To investigate associations between the physical or psychosocial work environment and labour market participation in early adulthood.

METHODS

The study was based on data from the West Jutland Cohort, an ongoing study of individuals born in 1989 who lived in the western part of Jutland, Denmark, in 2004. Participants were employed individuals who had questionnaire data on their work environment at age 28 and register information on labour market participation at ages 28-29 (n = 1312). The outcome was categorized into low (>4 weeks) versus high (≤4 weeks) labour market participation based on the total number of weeks receiving any unemployment or health-related benefits during a 52-week period. Logistic regression analyses were performed to examine associations between work environment factors and labour market participation, taking confounders into account.

RESULTS

Low influence, low quality of leadership, high job insecurity and temporary employment were associated with low labour market participation. High job insecurity (OR: 2.2; 95% CI 1.5-3.1) and temporary employment (OR: 3.1; 95% CI 2.1-4.5) were strongly associated with low labour market participation. An association was seen between hard physical work and low labour market participation.

CONCLUSIONS

Several physical and psychosocial work environment factors, especially high job insecurity and temporary employment, have a negative impact on labour market participation in early adulthood.

Development and validation of a prediction model for unemployment and work disability among 55 950 Dutch workers

Background

This study developed prediction models for involuntary exit from paid employment through unemployment and disability benefits and examined if predictors and discriminative ability of these models differ between five common chronic diseases.

Methods

Data from workers in the Lifelines Cohort Study (n = 55 950) were enriched with monthly information on employment status from Statistics Netherlands. Potential predictors included sociodemographic factors, chronic diseases, unhealthy behaviours and working conditions. Data were analyzed using cause-specific Cox regression analyses. Models were evaluated with the C-index and the positive and negative predictive values (PPV and NPV, respectively). The developed models were externally validated using data from the Study on Transitions in Employment, Ability and Motivation.

Results

Being female, low education, depression, smoking, obesity, low development possibilities and low social support were predictors of unemployment and disability. Low meaning of work and low physical activity increased the risk for unemployment, while all chronic diseases increased the risk of disability benefits. The discriminative ability of the models of the development and validation cohort were low for unemployment (c = 0.62; c = 0.60) and disability benefits (c = 0.68; c = 0.75). After stratification for specific chronic diseases, the discriminative ability of models predicting disability benefits improved for cardiovascular disease (c = 0.81), chronic obstructive pulmonary disease (c = 0.74) and diabetes mellitus type 2 (c = 0.74). The PPV was low while the NPV was high for all models.

Conclusion

Taking workers’ particular disease into account may contribute to an improved prediction of disability benefits, yet risk factors are better examined at the population level rather than at the individual level.

Multimorbidity and exit from paid employment: the effect of specific combinations of chronic health conditions

Background

This study aimed to assess the association between multimorbidity and exit from paid employment, and which combinations of chronic health conditions (CHCs) have the strongest association with exit from paid employment.

Methods

Data from 111 208 workers aged 18–64 years from Lifelines were enriched with monthly employment data from Statistics Netherlands. Exit from paid employment during follow-up was defined as a change from paid employment to unemployment, disability benefits, economic inactivity or early retirement. CHCs included cardiovascular diseases (CVD), chronic obstructive pulmonary disease (COPD), rheumatoid arthritis (RA), type 2 diabetes (T2DM) and depression. Cox-proportional hazards models were used to examine the impact of multimorbidity and combinations of CHCs on exit from paid employment.

Results

Multimorbidity increased the risk of exiting paid employment compared with workers without CHCs (hazard ratio (HR): 1.52; 95% confidence interval (CI): 1.35–1.71) or one CHC (HR: 1.14; 95% CI: 1.01–1.28). The risk for exit from paid employment increased among workers with COPD if they additionally had CVD (HR: 1.39; 95% CI: 1.03–1.88), depression (HR: 1.46; 95% CI: 1.10–1.93) or RA (HR: 1.44; 95% CI: 1.08–1.91), for workers with T2DM if they additionally had CVD (HR: 1.43; 95% CI: 1.07–1.91) or depression (HR: 2.09; 95% CI: 1.51–2.91) and for workers with depression who also had T2DM (HR: 1.68; 95% CI: 1.21–2.32).

Conclusion

This study showed that workers with multimorbidity, especially having a combination of COPD and depression or T2DM and depression, have a higher risk for early exit from paid employment and, therefore, may need tailored support at the workplace.

The Psychosocial Work Environment and Perceived Stress among Seniors with Physically Demanding Jobs: The SeniorWorkingLife Study

Background: Poor psychosocial work conditions are known to foster negative health consequences. While the existing literature on this topic focus mainly on white-collar workers, the influence of different aspects of the psychosocial work environment in physically demanding jobs remain understudied. Likewise, senior workers represent a population of the workforce at increased risk of adverse health outcomes and premature exit from the labour market. This study investigates the association between psychosocial work factors and perceived stress among the senior work force. Methods: Utilizing cross-sectional findings, this study reports associations between psychosocial factors (organizational justice, cooperation and collegial support, decision latitude, clarity of tasks, and quality of leadership) and the outcome of perceived stress quantified by Cohen’s Perceived Stress Scale (CPSS). Currently employed senior workers with physically demanding jobs were included in the analyses (n = 3386). Associations were modeled using general linear models with weights to make the estimates representative. Results: For all individually adjusted psychosocial variables, the category of “good” was consistently associated with lower stress scores compared to the categories of both “moderate” and “poor” (all p < 0.0001). Likewise, in the mutually adjusted analysis, the category of “good” was statistically different from “poor” for all included variables, while the category of “moderate” remained different from “poor” for “clarity of tasks”, “cooperation and collegial support”, and “decision latitude”. Conclusions: Among senior workers with physically demanding jobs, poor ratings of organizational factors related to the psychosocial work environment are consistently associated with high stress scores. Blue-collar occupations focusing primarily on physical risk factors are recommended to increase awareness on psychosocial aspects that may be relevant to the local work environment.

Trajectories of Procedural and Interactional Justice as Predictors of Retirement among Swedish Workers: Differences between Three Groups of Retirees

Organizational justice is an important aspect of the psychosocial work environment, but there is a lack of studies on whether justice perceptions also predict retirement decisions. The aim of this study is to examine trajectories of procedural and interactional justice perceptions prior to retirement of three groups of retirees while considering self-rated health and important demographics. Data from the Swedish Longitudinal Occupational Survey of Health (2006–2018, N = 3000) were used. Respondents were grouped into early retirement, normative retirement and late retirement. Latent growth curve models and multinomial logistic regressions were conducted to test whether trajectories of justice perceptions prior to retirement differed between retirement groups while controlling for self-rated health development and demographic variables. Late retirees had higher intercept levels of interactional justice and higher intercept levels of self-rated health prior to retirement, compared to early retirees. Late retirees also showed a slower decrease in procedural justice compared to early retirees. Only intercept levels of self-rated health differed between early retirees and normative retirees, such that early retirees had lower levels of self-rated health prior to retirement. Keeping employees in the workforce is a major challenge for any aging society. Organizational justice perceptions in the years prior to retirement seem particularly influential for delaying retirement.

The influence of age, gender and the FKBP5 genotype on subjective health complaints in the Norwegian working population

OBJECTIVE

In the present study we examined the potential association between age, gender, the genetic variant FKBP5 rs9470080 and subjective health complaints.

METHODS

The data were collected through a three-wave nationally representative survey of 1060 Norwegian employees drawn from the Norwegian Central Employee Register by Statistics Norway. The follow-up period was six months. Subjective health complaints were scored by eight items reflecting; headache, neck pain, mid- and low back pain, stomach cramps or intestinal discomfort, problems with sleep onset or maintenance and early morning awakening. Genotyping with regard to FKBP5 rs9470080, previously linked to cortisol sensitivity, was carried out using Taqman assay.

RESULTS

The baseline data showed that in women, levels of subjective health complaints were highest among those above 50 years of age. Moreover, in women the rs9470080 CC variant at baseline was associated with higher levels of subjective health complaints. However, the effect size was not large, and no relationships were demonstrated between age or genotype and subjective health complaints in men. Also, the study variables were not related to any changes in the levels of subjective health complaints during the follow-up period.

CONCLUSION

We conclude that our biology such as age and sex, but also single genetic variants found in non-sex chromosomes, may be important in understanding the mechanisms underlying subjective health complaints in the general working population.

Why Singles Prefer to Retire Later

This study goes beyond a purely financial perspective to explain why single older workers prefer to retire later than their partnered counterparts. We aim to show how the work (i.e., its social meaning) and home domain (i.e., spousal influence) contribute to differences in retirement preferences by relationship status. Analyses were based on multiactor data collected in 2015 among older workers in the Netherlands (N = 6,357) and (where applicable) their spouses. Results revealed that the social meaning of work differed by relationship status but not always as expected. In a mediation analysis, we found that the social meaning of work partically explained differences in retirement preferences by relationship status. We also show that single workers preferred to retire later than workers with a “pulling” spouse, earlier than workers with a “pushing” spouse, and at about the same time as workers with a neutral spouse.

Disabling working environments and mental health: A commentary

Employment is a fundamental Social Determinant of Health known to have large impacts on mental health and other health outcomes. Across many countries of the world, people with disabilities are much more likely to be unemployed and looking for work than those without disabilities. The deprivation of employment opportunities is likely to have notable impacts on the health of people with disabilities. In this commentary, we outline the concept of "disabling working environments," which are defined as the range of experiences that affect the likelihood of people with disabilities in obtaining and maintaining quality employment which may then affect a disabled person's health. Disabling working environments are comprised of the following three mutually reinforcing components: 1) Differential selection into work; 2) Selection into certain types of jobs and exposure to poor psychosocial working environments when in employment, and; 3) Differential selection out of work (e.g., leaving employment at an earlier age than those who do not have a disability). We argue that policy and intervention design should consider the life course effects of employment on the mental health of people with disabilities.

Assessment of the healthy worker survivor effect in the relationship between psychosocial work-related factors and hypertension

Objectives

The healthy worker survivor effect (HWSE) usually leads to underestimation of the effects of harmful occupational exposures. HWSE is characterised by the concomitance of three associations: (1) job status–subsequent exposure, (2) job status–disease and (3) previous exposure–job status. No study has reported the coexistence of these associations in the relationship between psychosocial work-related factors and health. We assessed if HWSE is present when measuring the effects of cumulative exposure to psychosocial work-related factors on the prevalence of hypertension in white-collar workers.

Methods

Data were obtained from two timepoints (1991–1993 at baseline and 1999–2001 at follow-up) of a prospective cohort study. At baseline, the population was composed of 9188 white-collar employees (women: 49.9%) in Quebec City. Job strain as psychosocial work-related factor and blood pressure were measured using validated methods. Job status (retirees vs employees) at follow-up was self-reported. Multiple multilevel robust Poisson regressions were used to estimate prevalence ratios of hypertension and risk ratios of retirement separately by gender. We performed multiple imputations to control selection bias due to missing values.

Results

Retirement eliminated the subsequent exposure to job strain de facto and was associated with the reduction in the prevalence of hypertension in younger (−33%) and older (−11%) men and in older women (−39%). Job strain was associated with job status in younger men and in women of any age.

Conclusion

Data showed the presence of HWSE in younger men and older women given the coexistence of the three structural associations.
