Longitudinal and Life Course Studies最新文献

Growing Up in Québec, also known as the Québec Longitudinal Study of Child Development, 2nd edition (QLSCD 2), is a prospective cohort that began in spring 2021. Its goal is to follow the development of Québec children from the age of five months to adulthood in about 4,500 families. It is conducted by the Institut de la statistique du Québec and is based on the Québec Longitudinal Study of Child Development, 1st edition (QLSCD 1), which began in 1998 and is still ongoing. This article describes the Growing Up in Québec pilot study started in 2018, focusing on its objectives and key stages of completion, namely content selection, recruitment strategies and the retention plan, collection methods, adjustments to strategies made during collection, and methodology, including the construction of a socio-economic poverty indicator for population stratification. The article continues by presenting pilot results and their implications for the main survey. It ends with recommendations from the pilot study, exemplifying the wealth of experience gained from it.

This article relies on a prospective qualitative study, that provides valuable insight into the mechanism through which the meaning of holidays is built over time. Following a life course perspective, the article analyses the continuities as well as the twists and turns of the meaning of Christmas in relation to significant turning points that occur along the paths of individual lives in transition to adulthood. Grounded on an inductive approach, the study draws on longitudinal qualitative data collected through solicited diaries, kept by 14 young Romanian adults, around Christmas time, along four panel waves (2004, 2010, 2016, 2020). Results show that there is no universal configuration of the meaning of Christmas, but rather a diversity of personalised dynamic configurations, in line with individuals' subjective realities, which are sensitive to family traditions passed down during socialisation, and constantly updated with each generation that assumes them, but also to significant life events that occurred on their early adult life course trajectories, determining a re-evaluation of attitudes about self, life, religion and others. The article concludes that Christmas, as a social construct, is a malleable bearer of values, which acts both as a 'sword' and as a 'shield' that diarists use according to the needs, wishes and challenges that arise in their transition from adolescence to enhanced adulthood.

Although a negative association between socio-economic inequalities and health has been established, there is a dearth of robust longitudinal studies examining this relationship in adolescents. This study used a large, nationally representative longitudinal data set to investigate the association between socio-economic inequality, subjective health status and disabilities among young people in Northern Ireland over a ten-year period. Data were from the Northern Ireland Longitudinal Study, a census-based record linkage study (N = 46,535). Logistic regression models were estimated in which health and disability variables from the 2011 census were predicted by household deprivation in education, housing quality, housing tenure and employment from the 2001 census. Models were adjusted for health and disability status in 2001. Deprivation in employment, housing tenure and coming from a single-parent household in 2001 independently predicted poorer subjective health and disability status ten years later [ORs = 1.28-1.93]. Deprivation in education in 2001 was also associated with increased risk of disability in 2011 [OR = 1.15; 95% CI = 1.06-1.25]. These results show that there is a need to dedicate more resources and support for economically disadvantaged children and young people in Northern Ireland, where child health outcomes are poorer than in the rest of the UK.

Background: Life course trajectories of affective symptoms (depression and anxiety) are heterogenous. However, few studies have investigated the role of early life risk factors in the development of these trajectories. The present study aimed to: (1) derive latent trajectories of affective symptoms over a period of more than 50 years (ages 13-69), and (2) examine early life risk factors for associations with specific life course trajectories of affective symptoms.

Method: Participants are from the MRC National Survey of Health and Development (NSHD) (n = 5,362). Affective symptoms were measured prospectively at ages 13, 15, 36, 43, 53, 60-64 and 69. A latent variable modelling framework was implemented to model longitudinal profiles of affective symptoms. Twenty-four prospectively measured early life predictors were tested for associations with different symptom profiles using multinomial logistic regression.

Results: Four life course profiles of affective symptoms were identified: (1) absence of symptoms (66.6% of the sample); (2) adolescent symptoms with good adult outcome (15.2%); (3) adult symptoms only (with no symptoms in adolescence and late life) (12.9%); (4) symptoms in adolescence and mid adulthood (5.2%). Of the 24 early life predictors observed, only four were associated with life course trajectories, with small effect sizes observed.

Conclusions: People differ in their life course trajectories of anxiety and depression symptoms and that these differences are not largely influenced by early life factors tested in this study.

Longitudinal surveys traditionally conducted by interviewers are facing increasing pressures to explore alternatives such as sequential mixed-mode designs, which start with a cheaper self-administered mode (online) then follow up using more expensive methods such as telephone or face-to-face interviewing. Using a designed experiment conducted as part of the 2018 wave of the Health and Retirement Study (HRS) in the US, we compare a sequential mixed-mode design (web then telephone) with the standard telephone-only protocol. Using an intent-to-treat analysis, we focus on response quality and response distributions for several domains key to HRS: physical and psychological health, financial status, expectations and family composition. Respondents assigned to the sequential mixed-mode (web) had slightly higher missing data rates and more focal responses than those assigned to telephone-only. However, we find no evidence of differential quality in verifying and updating roster information. We find slightly lower rates of asset ownership reported by those assigned to the web mode. Conditional on ownership, we find no detectable mode effects on the value of assets. We find more negative (pessimistic) expectations for those assigned to the web mode. We find little evidence of poorer health reported by those assigned to the web mode. We find that effects of mode assignment on measurement are present, but for most indicators the effects are small. Finding ways to remediate the differences in item-missing data and focal values should help reduce mode effects in mixed-mode surveys or those transitioning from interviewer- to self-administration.

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.
