Work-family life courses and metabolic markers in mid-life: evidence from the British National Child Development Study

Gendered work-family life courses and late-life physical functioning: A comparative analysis from 28 European countries

Combining work and family roles can have beneficial consequences on health but could also result in chronic stress and adverse health outcomes at older ages. This study aimed to examine combined employment, parenthood, and partnership histories of men and women during the childbearing period (ages 15-49), and to investigate the links of these work and family roles with physical functioning later in life. We used data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with retrospective information on employment, parenthood, and partnership histories for 18,057 men and 20,072 women (n = 38,129) living in 28 different countries belonging to six European welfare clusters. We applied multichannel sequence analysis (MCSQA) and hierarchical clustering to group work-family trajectories into 12 clusters for men and 15 clusters for women. We assessed the association between work-family life courses and grip strength by estimating multivariable linear regression models. Delayed work and family transitions, unstable employment, and the absence of combinations of work and family roles between age 15 and 49 were associated with weaker grip strength in later life for both men and women. Results differed by gender and were framed by the welfare context in which gendered work and family responsibilities unfold across individual life courses. The findings make an important contribution to the domain of gender and health in later life and stress the need to engage more with issues related to the mechanisms linking work and family trajectories to poor health in later life.

Work-family trajectories and health: A systematic review

BACKGROUND

Work and family lives interact in complex ways across individuals' life courses. In the past decade, many studies constructed work-family trajectories, some also examined the relation with health. The aims of this systematic review were to summarise the evidence from studies constructing work-family trajectories, and to synthesise the evidence on the association between work-family trajectories and health.

METHODS

We searched MEDLINE, EMBASE, PsycINFO, SocINDEX and Web of Science databases. Key search terms related to work, family and trajectories. Studies that built combined work-family trajectories or examined the relationship between work and family trajectories were included. Risk of bias was assessed independently by two authors. The identified work-family trajectories were summarised and presented for men and women, age cohorts and contexts. The evidence on the association with health as antecedent or consequence was synthesised.

RESULTS

Forty-eight studies, based on 29 unique data sources, were included. Thirty-two studies (67%) were published in 2015 or later, and sequence analysis was the primary analytic technique used to construct the trajectories (n = 43, 90%). Trajectories of women were found to be more diverse and complex in comparison with men. Work-family trajectories differed by age cohorts and contexts. Twenty-three studies (48%) examined the association between work-family trajectories and health and most of these studies found significant associations. The results indicate that work-family trajectories characterised by an early transition to parenthood, single parenthood, and weak ties to employment are associated with worse health outcomes.

CONCLUSIONS

Work-family trajectories differed greatly between men and women, but differences seemed to decrease in the youngest cohorts. Given the current changes in labour markets and family formation processes, it is important to investigate the work and family lives of younger cohorts. Work-family trajectories were associated with health at different life stages. Future research should examine longitudinal associations of work-family trajectories with health and focus on elucidating why and under which circumstances some trajectories are associated with better or worse health compared with other trajectories.

Gender, work-family conflict, and weight gain: four-year follow-up of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

This study sought to analyze the effect of work-to-family conflict (demands from work that affect one's family/personal life), family-to-work conflict (demands from family/personal life that affect work), and lack of time for self-care and leisure due to professional and domestic demands on the incidence of weight gain and increase in waist circumference by gender in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Our study included 9,159 ELSA-Brasil participants (4,413 men and 4,746 women) who attended baseline (2008-2010) and the first follow-up visit (2012-2014). Weight gain and increase in waist circumference were defined as an annual increase ≥ 75th percentile, i.e., ≥ 1.21kg/year and ≥ 1.75cm/year, respectively for women; and ≥ 0.96kg/year and ≥ 1.41cm/year respectively for men. Associations were estimated by Poisson regression applying robust variance with the R software. Analyses were stratified by gender and adjusted for socioeconomic variables. Adjusted models showed a higher risk of weight gain among women who reported family-to-work conflict frequently and sometimes (relative risk - RR = 1.37 and RR = 1.15, respectively) and among those who reported frequent lack of time for self-care and leisure (RR = 1.13). Among men, time-based work-to-family conflict (RR = 1.17) and strain-based work-to-family conflict (RR = 1.24) were associated with weight gain. No associations were observed between work-family conflict domains and increase in waist circumference. These findings suggest that occupational and social health promotion programs are essential to help workers balance work and family life to reduce weight gain.

Multiple social roles in early adulthood and later mental health in different labour market contexts

Work and family roles entail divergent responsibilities, which can be a source of conflict especially in young adulthood - the so-called "rush-hour" of life. Combining these multiple social roles can result in an accumulation of stress but also be a valuable resource for mental health. The aim of this study is to investigate combined employment, parenthood and partnership trajectories of men and women during early adulthood, and to analyse the relationship of these multiple roles with depressive symptoms at older age. We used harmonised data from the Survey of Health, Ageing and Retirement in Europe (SHARE) and the English Longitudinal Study of Ageing (ELSA) with retrospective information on employment, partnerships and parenthood histories between age 25 and 40 for 18,816 men and 24,686 women (n = 43,502). We applied sequence analysis and clustering to group trajectories into four clusters for women and three clusters for men. We then used multilevel models to analyse the links between combined employment and family roles and later mental health in different historical labour market contexts (indicated by female employment rates). Women and men who did not combine work and family roles between age 25 and 40 report higher levels of depression than those who combined work and family. Results differ by gender and labour market context, with stronger differences between women in countries with higher female employment rates. Overall, combining multiple roles in early adulthood is associated with decreased rather than increased risk for depressive symptoms in older Europeans.

Work-family life courses and psychological distress: Evidence from three British birth cohort studies

This study uses multi-channel sequence analysis to characterize work-family life course types between the ages of 16 and 42, and multivariable logistic regression to examine their association with psychological distress at age 42/43 for men and women in three nationally-representative British birth cohorts born in 1946 (N = 2,858), 1958 (N = 9,140), and 1970 (N = 7,095). We hypothesised that work-family life courses characterized by weaker links to employment and earlier transitions to partnerships and parenthood would be associated with a greater probability of psychological distress at age 42, and that this association would be become more pronounced across cohorts. Levels of psychological distress were higher amongst men and women with weaker long-term ties to employment, although these were largely explained by early life factors. Teen mothers had higher levels of psychological distress in the two later-born cohorts, and this remained unexplained in adjusted models for the 1970 cohort.

Lifetime employment histories and their relationship with 10-year health trajectories in later life: evidence from England

Background

Employment histories influence health. However, most studies have so far investigated cross-sectional associations between employment histories and health, failing to recognize health as a dynamic process in later life.

Methods

We use Waves 3–8 of the English Longitudinal Study of Ageing, including retrospective information on respondents’ employment activities. We used dynamic hamming distances to summarize lifetime employment histories up to state pension age (64 for men and 59 for women). Multilevel growth curve models were then used to estimate the influence of lifetime employment histories on later life health trajectories over a 10-year period using quality of life (QoL), somatic health, and depression.

Results

Net of selection effect and a host of contemporaneous material and social resources, men who exited early started off with poorer health than those with continuous attachment to the labour market but had a very similar health profile by the end of the 10-year period considered. Among women, better somatic health and higher QoL were observed among those who had employment breaks for family care, and this health advantage was maintained over time. Lifetime employment histories are not related to depression for either men or women.

Conclusion

Overall, differences in health by employment histories level off only among men who left earlier and those continuously employed. Flexible arrangements for men in poor health who benefit from leaving the labour market early and supporting women who wish to take breaks for family care may help reduce health inequalities in later life.

Lifetime employment, tobacco use, and alcohol consumption trajectories and cardiovascular diseases in old age

Despite the great advances of life course epidemiology studies during the last decade in understanding the general health effects of employment trajectories, research has yet to evaluate the effects of employment trajectories along with other major risk factors, such as tobacco and alcohol consumption, on cardiovascular diseases (CVDs)-the main cause of deaths worldwide. This is highly relevant, since health advantages in one domain (e.g., being a permanent formal full-time worker) may offset health disadvantages in other domains (e.g., being a regular smoker or alcohol consumer); conversely, disadvantages in both domains may interact, leading to even greater health risks. Considering these knowledge gaps, this research has two main objectives: (1) to reconstruct simultaneous employment, tobacco use, and alcohol consumption trajectories over the life course (from birth to old age) and (2) to measure the association between these trajectories and CVD in old age. Drawing on a rich and comprehensive life history dataset and using multichannel sequence and regression analyses, we analyzed a cohort of individuals aged 65-75 in Chile, a Latin American country with high social inequalities and scarce research on this matter. Our study shows that following a trajectory of formal employment together with no tobacco and alcohol use reduces CVD risk by 36 percentage points relative to a similar employment trajectory but with regular tobacco and alcohol use. Even with an employment trajectory characterized by constant informal employment or permanent inactivity, a life course free of regular tobacco and alcohol use shows protective effects against CVD. This study stresses the importance of health policies that consider CVD as a condition that strongly depends on individual experiences in multiple life domains and across different life stages.

The role of education and other transition milestones in the progression of social inequalities in cigarette smoking between the ages of 18 and 25: Evidence from the Canadian National Population Health Survey

Young adulthood is now considered a sensitive period in the progression of health inequalities over the life-course. This age group experiences highly dynamic and socially patterned life-course events that require nuanced modelling choices compared to those commonly used in public health sciences. To illustrate this, we estimate changes in the risk of smoking according to student status, employment status, living arrangements, and relationship status at different ages across education categories. We used longitudinal data in 1,243 young adults followed every two years between the ages of 18-19 and 24-25 in the Canadian National Population Health Survey (1994-95 to 2010-11). We examined the age-graded associations of occasional and daily smoking with educational attainment and transition statuses using random-effects multinomial logistic regression models with interaction terms. Post-secondary education, living with parents, studying, and being in a relationship were associated with a lower risk of daily smoking in main models, with some of these associations significantly varying in magnitude by age. The risk associated with living without parents at ages 18-19 disappeared by ages 24-25. Being single was both a protective factor at ages 18-19 and a risk factor at ages 24-25. Finally, the risk associated with being single was also stronger among those who did not pursue post-secondary education. These findings support the argument that the simple conceptualization of young adults' circumstances - independent from age and social context - provides a limited understanding of the progression of health inequalities over the life-course. Research needs to consider the dynamic and intersecting nature of transition milestones during this intensive life period.

Linked work lives: The interrelation of own and partner's employment history and their relationship with mental health in older European couples

INTRODUCTION

There is strong evidence for the importance of previous employment for mental health at older age but little is known about the role of partner's employment history in this. Life course theory suggests that individual trajectories are linked and evidence from cross-sectional studies suggest that there are cross-over effects within couples. Therefore, the present study tests the interdependence of own and partner's employment history and their relationship with depressive symptoms.

METHODS

Analyses are based on retrospective data from the SHARE survey for 5664 long-term couples aged 50 or older, with employment information for each age between 30 and 50 (full-time, part-time, domestic work or non-employed). We use sequence analysis to group similar employment histories and relate own and partner's employment histories with depressive symptoms (EURO-D) using regression models.

RESULTS

Results show that own and partner's employment history are interdependent and mainly follow traditional divisions of paid work, with the majority of men working full-time and women often working part-time or not working. We find increased depressive symptoms after longer episodes of non-employment for men but not for women, regardless of partner's employment situation.

CONCLUSION

The study shows that mental health later in life is related to own employment history and that this relationship is not moderated by partner's employment history. The results need to be interpreted against cultural and gender role norms at the time.

Finding Jobs, Forming Families, and Stressing Out? Work, Family, and Stress among Young Adult Women in the United States

The transition to adulthood is increasingly characterized by complex paths into the world of work and family, especially for young women. Yet how work and family combine to influence stress among young adult women is not well understood. Using data from the National Longitudinal Study of Adolescent to Adult Health, we leverage new extensions to latent class analysis (LCA) to identify common combinations of work and family circumstances among young adult women, their earlier life and contemporaneous correlates, and associations with two stress measures: a multi-item Perceived Stress Scale (PSS) and Epstein–Barr Viral (EBV) antibody titers, a well-validated biomarker of stress-related immunity impairments. We identify seven different common combinations of latent work–family combinations among young adult women ranging from well-compensated professional workers with and without children, mothers without paid employment, and delayed transitions to work and family. Completing a college degree was associated with a higher likelihood of membership in classes marked by professional work irrespective of motherhood, while being raised in a community with greater female labor opportunities was generally associated with membership in child-free classes. Mothers and child-free women in “pink-collar” work with low wages and decision-marking freedom reported higher stress compared to women in “white-collar” work with higher wages and decision-making freedom. These differences are mostly attenuated following adjustments for poverty-related stressors and work–family conflict. While prior work has emphasized the health benefits for women of combining work and family, our research suggests these benefits may be limited to women of higher socioeconomic status with flexible, well-compensated jobs.

Social sequencing to determine patterns in health and work-family trajectories for U.S. women, 1968-2013

BACKGROUND

Women's social roles (partnership, parenthood, and worker status) are associated with health, with more roles being associated with lower mortality rates. Few studies have examined social roles using a lifecourse perspective to understand how changing role dynamics affect health over time. Sequence analysis is one analytic technique for examining social trajectories.

METHODS

Work-family trajectories were determined using social sequence analysis. We estimated mortality using age-standardized mortality rates and Poisson regression and examined the impact of personal income as a mediator.

RESULTS

We identified 5 trajectory types according to probability distributions of work/marriage/child-rearing status and descriptions in previous research: Non-working, married, later-mothers; working divorced mothers; working and non-working, never-married mothers; working, never-married non-mothers; and non-working, married earlier-mothers. Our reference group, non-working, married, later-mothers had the lowest mortality rates (1.47 per 1000 person-years). Adjusting for confounders, timing of childbearing did not impact mortality rates for married, non-working women. Working, never-married non-mothers and working and non-working, never-married mothers had the highest adjusted rates of mortality (RR = 1.81 and 1.57, respectively) these effects were attenuated slightly by the addition of household income in the model. Mortality rates for other trajectory groups were not significantly elevated in adjusted models.

CONCLUSIONS

Mortality rates vary by work-family trajectories, but timing of childbearing does not meaningfully impact risk among women in this population, likely because few of the women who were married and had children also worked full-time. Household income has some mediating effect among those at highest risk of early mortality.

Do work and family care histories predict health in older women?

Background

Social and policy changes in the last several decades have increased women’s options for combining paid work with family care. We explored whether specific combinations of work and family care over the lifecourse are associated with variations in women’s later life health.

Methods

We used sequence analysis to group women in the English Longitudinal Study of Ageing according to their work histories and fertility. Using logistic regression, we tested for group differences in later life disability, depressive symptomology and mortality, while controlling for childhood health and socioeconomic position and a range of adult socio-economic circumstances and health behaviours.

Results

Women who transitioned from family care to either part-time work after a short break from the labour force, or to full-time work, reported lower odds of having a disability compared with the reference group of women with children who were mostly employed full-time throughout. Women who shifted from family care to part-time work after a long career break had lower odds of mortality than the reference group. Depressive symptoms were not associated with women’s work and family care histories.

Conclusion

Women’s work histories are predictive of their later life disability and mortality. This relationship may be useful in targeting interventions aimed at improving later life health. Further research is necessary to explore the mechanisms linking certain work histories to poorer later life health and to design interventions for those affected.

Fertility History and Physical and Mental Health Changes in European Older Adults

Previous studies have shown that aspects of reproductive history, such as earlier parenthood and high parity, are associated with poorer health in mid and later life. However, it is unclear which dimensions of health are most affected by reproductive history, and whether the pattern of associations varies for measures of physical, psychological and cognitive health. Such variation might provide more insight into possible underlying mechanisms. We use longitudinal data for men and women aged 50–79 years in ten European countries from the Survey of Health, Ageing and Retirement in Europe to analyse associations between completed fertility history and self-reported and observed health indicators measured 2–3 years apart (functional limitations, chronic diseases, grip strength, depression and cognition), adjusting for socio-demographic, and health factors at baseline. Using multiple imputation and pattern mixture modelling, we tested the robustness of estimates to missing data mechanisms. The results are partly consistent with previous studies and show that women who became mothers before age 20 had worse functional health at baseline and were more likely to suffer functional health declines. Parents of 4 or more children had worse physical, psychological and cognitive health at baseline and were more likely to develop circulatory disease over the follow-up period. Men who delayed fatherhood until age 35 or later had better health at baseline but did not experience significantly different health declines. This study improves our understanding of linkages between fertility histories and later life health and possible implications of changes in fertility patterns for population health. However, research ideally using prospective life course data is needed to further elucidate possible mechanisms, considering interactions with partnership histories, health behaviour patterns and socio-economic trajectories.

Work-family life courses and BMI trajectories in three British birth cohorts

BACKGROUND/OBJECTIVES:

Combining work and family responsibilities has previously been associated with improved health in mid-life, yet little is known about how these associations change over time (both biographical and historical) and whether this extends to body mass index (BMI) trajectories for British men and women. The purpose of this study was to investigate relationships between work-family life courses and BMI trajectories across adulthood (16–42 years) for men and women in three British birth cohorts.

SUBJECTS/METHODS:

Multiply imputed data from three nationally representative British birth cohorts were used—the MRC National Survey of Health and Development (NSHD; 1946 birth cohort, n=3012), the National Child Development Study (NCDS; 1958 birth cohort, n=9614) and the British Cohort Study (BCS; 1970 birth cohort, n=8140). A typology of work-family life course types was developed using multi-channel sequence analysis, linking annual information on work, partnerships and parenthood from 16 to 42 years. Work-family life courses were related to BMI trajectories using multi-level growth models. Analyses adjusted for indicators of prior health, birthweight, child BMI, educational attainment and socioeconomic position across the life course, and were stratified by gender and cohort.

RESULTS:

Work-family life courses characterised by earlier transitions to parenthood and weaker long-term links to employment were associated with greater increases in BMI across adulthood. Some of these differences, particularly for work-family groups, which are becoming increasingly non-normative, became more pronounced across cohorts (for example, increases in BMI between 16 and 42 years in long-term homemaking women: NSHD: 4.35 kg m^–2, 95% confidence interval (CI): 3.44, 5.26; NCDS: 5.53 kg m^–2, 95% CI: 5.18, 5.88; BCS: 6.69 kg m^–2, 95% CI: 6.36, 7.02).

CONCLUSIONS:

Becoming a parent earlier and weaker long-term ties to employment are associated with greater increases in BMI across adulthood in British men and women.
