Women's Work Pathways Across the Life Course.

ABSTRACT: Despite numerous changes in women's employment in the latter half of the twentieth century, women's employment continues to be uneven and stalled. Drawing from data on women's weekly work hours in the National Longitudinal Survey of Youth (NLSY79), we identify significant inequality in women's labor force experiences across adulthood. We find two pathways of stable full-time work for women, three pathways of part-time employment, and a pathway of unpaid labor. A majority of women follow one of the two full-time work pathways, while fewer than 10% follow a pathway of unpaid labor. Our findings provide evidence of the lasting influence of work-family conflict and early socioeconomic advantages and disadvantages on women's work pathways. Indeed, race, poverty, educational attainment, and early family characteristics significantly shaped women's work careers. Work-family opportunities and constraints also were related to women's work hours, as were a woman's gendered beliefs and expectations. We conclude that women's employment pathways are a product of both their resources and changing social environment as well as individual agency. Significantly, we point to social stratification, gender ideologies, and work-family constraints, all working in concert, as key explanations for how women are "tracked" onto work pathways from an early age.

Project description:PURPOSE:The Danish Work Life Course Cohort (DaWCo) was initiated to study relations between working conditions, health and labour market affiliation using repeated measures of these factors throughout the working life, while accounting for health-differences pre-existing labour market entry. PARTICIPANTS:The cohort encompasses all 15-30-year-old individuals residing in Denmark who entered the labour market during the years 1995-2009 (960 562 individuals and 7 136 188 observations). Data include information on working conditions measured by job exposure matrices linked with registers on health, labour market affiliation and sociodemographics for both the cohort members and their parents. The median age at cohort entry was 20 years and men and women were equally represented. FINDINGS TO DATE:Currently, one study has been published, which found that low job control was associated with increased risk of depressive disorder, independently from indicators of socioeconomic position measured throughout the life-course. The present cohort profile presents data regarding the transitions of cohort members between states of labour market affiliation and data on health services use. All cohort members were employed in their year of entry, but this proportion decreased across the years to 82.4% in the 10th year since cohort entry. The proportion of students peaked at 5 years since cohort entry with 13.9%. FUTURE PLANS:This large prospective cohort offers the possibility to study associations between psychosocial working conditions and rare outcomes and to examine the potential accumulation of effects while accounting for health-differences pre-existing labour market entry. Currently, we are working on analyses on risk of hospital-diagnosed incident depression and disability pensioning. The study is ongoing, and we are planning to extend the study to include the years 2010-2018 and expand the cohort with individuals entering the Danish workforce during these years.

Project description:Introduction: At the molecular level, cellular aging involves changes in multiple gene pathways, which can produce many aging phenotypes. In the liver, senescence changes lead to impaired hepatic function. We hypothesized that the natural hepatic aging process is driven by sex-dependent mechanisms. Purpose: We studied our well-established model of aging in which we have previously determined aging of metabolism, reproduction and endocrine systems. We performed liver transcriptomics (RNA-seq) on male and female rats at 110 and 650 days (d) fed with normal rat chow to determine changes key signaling pathways related to senescence processes. Methods: To identify the functional F1 liver changes due to natural aging processes, we evaluated the differentially expressed genes (DEGs) between 650d and 110d in males and females, with separate pairwise comparisons due to the marked differences. Genes were filtered based on ?1.4 fold change (FC) and nominal P value <0.05 (Studentｴs t-test). Results: We found that the natural liver aging process shows sex-differences. RNA-seq revealed more male (3,967) than female (283) differentially expressed genes (DEG) and pathways over the 110d to 650d period studied. Cell cycle pathway signaling in males was accompanied by decreased protein and gene expression of key genes (CDK2, CDK4, Cycd and PCNA) and an increase of p57 at 650d vs. 110d. In females, protein and gene expression of cell growth regulators such as p15 and p21, that inhibit cell cycle G1 progression were increased. Moreover, additionally the cell senescence pathway showed sexual dimorphism in liver gene regulation. Conclusions: Our results demonstrate how the natural aging process affects the liver transcriptome signature in a sex-dependent manner, specifically in cell cycle and cell senescence pathways, pathways that contribute in a major fashion to the development of aging-induced liver diseases. Understanding cellular senescence pathways involved in the natural aging process will aid evaluation of mechanisms associated with altered aging and frailty trajectories.
