Longitudinal and Life Course Studies最新文献

Understanding of how socio-economic disadvantage experienced over the life course relates to mental health outcomes in young adulthood has been limited by a lack of long-term, prospective studies. Here we address this limitation by drawing on data from a large Australian population cohort study that has followed the development of more than 2,000 Australians (and their families) from infancy to young adulthood since 1983. Associations were examined between prospective assessments of socio-economic position (SEP) from 4-8 months to 27-28 years and mental health problems (depression, anxiety, stress) and competence (civic engagement, emotional maturity, secure intimate relationship) at 27-28 years. The odds of being socio-economically disadvantaged in young adulthood were elevated eight- to tenfold in those who had experienced disadvantage in the family of origin, compared with those who had not (OR 8.1, 95% CI 4.5-14.5 to 10.1, 95% CI 5.2-19.5). Only concurrent SEP was associated with young adult mental health problems, and this effect was limited to anxiety symptoms (OR 2.0, 95% CI 1.1-3.9). In contrast, SEP had more pervasive impacts on young adult competence, particularly in the civic domain where effects were evident even from early infancy (OR 0.46, 95% CI 0.26-0.81). Findings suggest that one potentially important mechanism through which disadvantage compromises mental health is through limiting the development and consolidation of key psychosocial competencies needed for health and well-being in adulthood.

We use longitudinal register data from Sweden to study patterns and dynamics in lifetime income trajectories. We examine divergences in these income trajectories by local economic conditions at labour market entry, in combination with other factors such as gender, education level and socio-economic background. We cannot assume that these relationships are constant over the course of individuals' working lives. Therefore, we use methods from functional data analysis, allowing for a time-varying relationship between income and the explanatory variables. Our results show a large degree of heterogeneity in how lifetime income trajectories develop for different subgroups. We find that, for men, entering the labour market in an urban area is associated with higher cumulative lifetime income, especially later in life. The exception is men with only primary education, for whom those starting their working lives in a large city have lower incomes on average. This divergence increases in size over time. Women who enter into a large urban labour market receive higher lifetime income at all education levels. This relationship is strongest for women with primary education but decreases in strength over time for these women.

Background: Risk-taking behaviours are a major contributor to youth morbidity and mortality. Vulnerability to these negative outcomes is constructed from individual behaviour including risk-taking, and from social context, ecological determinants, early life experience, developmental capacity and mental health, contributing to a state of higher risk. However, although risk-taking is part of normal adolescent development, there is no systematic way to distinguish young people with a high probability of serious adverse outcomes, hindering the capacity to screen and intervene. This study aims to explore the association between risk behaviours/states in adolescence and negative health, social and economic outcomes through young adulthood.

Methods: The Raine Study is a prospective cohort study which recruited pregnant women in 1989-91, in Perth, Western Australia. The offspring cohort (N = 2,868) was followed up at regular intervals from 1 to 27 years of age. These data will be linked to State government health and welfare administrative data. We will empirically examine relationships across multiple domains of risk (for example, substance use, sexual behaviour, driving) with health and social outcomes (for instance, road-crash injury, educational underachievement). Microsimulation models will measure the impact of risk-taking on educational attainment and labour force outcomes.

Discussion: Comprehensive preventive child health programmes and policy prioritise a healthy start to life. This is the first linkage study focusing on adolescence to adopt a multi-domain approach, and to integrate health economic modelling. This approach captures a more complete picture of health and social impacts of risk behaviour/​states in adolescence and young adulthood.

Young adults are co-residing with their parents at higher rates now than in the past, and recent research has explored the correlates of both leaving and subsequently returning to the parental home. Of relevance here, females tend to leave home earlier than their male counterparts, and research finds that drinking and drug use are also linked to residential transitions. This research note explores if substance use during adolescence and young adulthood plays a role in gender differences in home-leaving and home-returning. We find that marijuana use plays a role in both home-leaving and home-returning, with adolescent females who use marijuana the most at risk for early exits from home, and marijuana using males the most at risk for home-returning.

There has been much debate over the micro-level relationship between employment situations and fertility in Europe and Northern America. However, related research in East Asia is scant, although countries in this region have some of the lowest fertility rates in the world. Moreover, most studies analyse the employment-fertility relationship from a static perspective and only for women, which underemphasises life course dynamics and gender heterogeneity of employment careers and their fertility implications. Drawing on retrospective data from the 2017 Taiwan Social Change Survey (TSCS), this study explores women's and men's career trajectories between ages 18 and 40 in Taiwan using sequence cluster analyses. It also examines how career variations associate with different timing and quantum of birth. Empirical results show that economically inactive women experience faster motherhood transitions and have more children by age 40 than women with stable full-time careers. For men, having an unstable career associates with slower fatherhood transitions and a lower number of children. For both genders, self-employed people are the earliest in parenthood transitions and have the highest number of children by midlife. Our findings demonstrate sharp gender contrasts in employment careers and their diversified fertility implications in low-fertility Taiwan.
