The Heterogeneity of Partnership Trajectories to Childlessness in Germany.

ABSTRACT: In recent decades, childlessness has increased across many European countries. In addition to socioeconomic characteristics, having a partner is considered a prerequisite in most fertility studies. Yet, still little is known about the partnership biographies of childless women and men. We assess the heterogeneity in the partnership trajectories of childless persons in Germany and explore compositional differences of partnership trajectories by gender and education. We use data from the German Family Panel to reconstruct partnership biographies reflecting the occurrence and frequency of different partnership states (singleness, living apart together, cohabitation, marriage). The sample comprises women and men born 1971-1973 whose life courses are observed from age 18-40. Applying sequence and cluster analysis, we identify five patterns of partnership trajectories: (1) 'Marriage' (14.6%); (2) 'Long-term cohabitation' (11.8%) with one partner; (3) 'Serial cohabitation' (15.6%); (4) 'LAT' (18.8%), long-term/multiple living-apart-together relationships; and (5) 'Single' (39.3%), long-term singleness. Men are overrepresented in the 'Single' cluster, especially if highly educated. Women are more often married and more likely to experience long-lasting singleness or multiple LAT episodes when being highly educated. We speculate that theories predicting high levels of childlessness in contexts where gender norms and work-family policies do not account for the increasing gender equality in education and labor force participation might also explain differences in the pathways leading to childlessness. Generally, our findings point at a more elaborate conceptualization of childlessness that moves away from a binary cross-sectional indicator and set the ground for future cross-national comparisons.

Project description:ObjectivesPrevious studies have shown marital status differences in incidence and prevalence of cardiovascular disease and cardiovascular mortality. This study examines the consequences of partnership on biomarkers related to cardiovascular health of older men and women in Germany and England (C-reactive protein, HbA1c, systolic and diastolic blood pressure; and total cholesterol).MethodsData used is from older adults (60 +) from the German Survey of Health and Retirement Europe SHARE (n=955) and the English Longitudinal Study of Ageing ELSA (n=9707). Life course partnership is measured using the timing (age at first partnership), quantum (number of partnerships) and partnership trajectory. OLS for C-reactive protein, logistic regressions for systolic and diastolic blood pressure, and multinomial logistic regressions for cholesterol are used to investigate the associations between life course partnership characteristics and biomarkers, accounting for early age socioeconomic and health conditions.ResultsTiming of first partnership is associated with poor cardiovascular health in England, number of partnership transitions with poor health in Germany, and partnership trajectories are associated with cardiovascular health both in Germany and England. Men in trajectories with multiple marriages have higher CRP, and are more likely to have elevated systolic and diastolic BP. Trajectories containing single marital disruption for men and women are no longer associated with poor health after accounting for selection effects of childhood conditions. Respondents in widowed partnership trajectories have poorer cardiovascular health compared to those in intact committed relationships, whereas cohabitation trajectories do not differ in the associations with biomarkers from those in intact marriage.ConclusionThe results offer better understanding of the pathways through which family events and processes are linked to health and support the hypothesis that adversity related to partnerships over the life course accumulates and contributes to worse cardiovascular health in later life measured by objective health measures.

Project description:STUDY QUESTION:Does maternal age at a daughter's birth predict her subsequent probability of lifelong childlessness? SUMMARY ANSWER:In this study population, women born to older mothers were more likely to be childless. WHAT IS KNOWN ALREADY:Although maternal age at childbearing is increasing in many countries, there is limited evidence on whether being born to older parents may influence offspring fertility. STUDY DESIGN SIZE AND DURATION:This analysis included 43 135 women from the US-based Sister Study, a cohort study of 50 884 sisters of women with breast cancer recruited between 2003 and 2009. PARTICIPANTS/MATERIALS, SETTING, METHODS:Participants had no breast cancer at baseline. Women were included in the analytic sample if they were born between 1930 and 1964 and were at least 44 years old at enrolment. Median age when reproductive history was last ascertained was 63.8 years. We estimated relative risks (RR) and 95% CI of lifelong childlessness as a function of maternal age at birth, using multivariable log-binomial models, including total number of siblings, birth order, socioeconomic indicators of the family of origin, race and birth cohort. We examined the association in different subgroups and in a sibling-matched analysis including 802 sister pairs discordant for childlessness. MAIN RESULTS AND ROLE OF CHANCE:Compared with women born to 20-24-year-old mothers, those born to mothers aged 25-29, 30-34 and ?35 years were more likely to be childless [RR (95% CI): 1.21 (1.14-1.29), 1.30 (1.22-1.39) and 1.40 (1.31-1.50), respectively]. The association was consistent in strata defined by birth cohort, number of siblings, birth order, and participant's educational level, as well as within sister pairs. Overall, we found weak evidence for an independent contribution of paternal age at birth to the daughter's probability of childlessness. LIMITATIONS REASONS FOR CAUTION:All participants had at least one sister, and all information was self-reported. We had no knowledge of whether childlessness was intentional and found only a modest association between maternal age at birth and self-reported indicators of infertility. Still, the association with childlessness was highly consistent. WIDER IMPLICATIONS OF THE FINDING:Given the widespread tendency to delay childbearing, evaluating the influence of maternal age at birth on offspring fertility is a public health priority. STUDY FUNDING/COMPETING INTERESTS:This research was supported in part by the Intramural Research Programme of the NIH, National Institute of Environmental Health Sciences (Z01-ES044005). The authors report no conflict of interest.
