Recent labor market transformations brought on by digital and technological advances, together with the rise of the service economy since the 1980s, have subjected more workers to precarious conditions, such as irregular work hours and low or unpredictable wages, threatening their economic well-being and health. This study advances our understanding of the critical role employment plays in our health by examining how employment patterns throughout our working lives, based on work schedules, may shape our health at age 50, paying particular attention to the moderating role of social position. The National Longitudinal Survey of Youth-1979 (NLSY79), which has collected 30+ years of longitudinal information, was used to examine how employment patterns starting at ages 22 (n ≈ 7,336) might be associated with sleep hours and quality, physical and mental functions, and the likelihood of reporting poor health and depressive symptoms at age 50.

Objective: As labor markets have become increasingly volatile and precarious since 1980s, more workers are susceptible to working conditions such as unpredictable and unstable hours, threatening their economic security. However, our understanding of employment patterns regarding the changes in work schedules over our working lives has yet been established. This study builds our knowledge in this area by paying attention to how social positions may shape the specific work schedule patterns over our working lives.

Objective: As labor markets in recent decades have become increasingly volatile and precarious, more workers are susceptible to working conditions threatening their economic security. COVID-19 has further laid bare such economic insecurity from holding a precarious job. We examined the association between precarious employment and the probability of losing income or a job during COVID-19 pandemic.

Since the mid-1990s, information technology, particularly the diffusion of the internet, has brought tremendous changes to communication and social participation for people in China, including older adults. At the same time, modernisation and urbanisation have transformed the way many people in China live. The traditional multigenerational household-older adults living with adult children and grandchildren-is giving way to other living arrangements, such as living alone or with a spouse only.

Using a sample of Chinese adults over the age of 50 from wave 1 of the WHO Study on Global Ageing and Adult Health (n = 13,367), we investigated the relationship between living arrangements and subjective well-being (SWB) in regard to life satisfaction, happiness, and control. We also looked at the moderating role of resources, proxied by income and status. Multivariate regression results indicate that living only with a spouse was significantly associated with better SWB.

The COVID-19 pandemic brings to the forefront the complex interconnected dilemmas of globalization, health equity, economic security, environmental justice, and collective trauma, severely impacting the marginalized and people of color in the United States. This lack of access to and the quality of healthcare, affordable housing, and lack of financial resources also continue to have a more significant impact on documented and undocumented immigrants. This paper aims at examining these critical issues and developing a framework for family therapists to address these challenges by focusing on four interrelated dimensions: cultural values, social determinants of health, collective trauma, and the ethical and moral responsibility of family therapists.

This study examined the association between grandparental co-residence and child academic and behavioral outcomes using a sample from Shanghai, China (n = 1,763), and was built on two theoretical perspectives: intergenerational solidarity theory and the contextual model of family stress. These models integrate the impact of residential and relational proximity to grandparents on child well-being and underscore the importance of family context. This study also explored the moderating effects of family resources using proxies that prior theoretical and empirical studies have found to be important to such associations: family income, parental education, hukou status, and subjective social status.

Purpose: Childhood overweight and obesity is on the rise in China and in Chinese cities in particular. The aim of this study is to explore the extent of income differences in childhood overweight in Shanghai, China, and examine demographic, social, and behavioral explanations for these differences.

Methods: Using the 2014 Child Well-Being Study of Shanghai, China-a survey that included extensive contextual information on children and their families in China's most populous city, prevalence rates and adjusted odds ratios of child overweight and obesity at age 7 were calculated by income tercile controlling for a wide variety of sociodemographic variables.

Using Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K), we investigated the relationship between poverty and academic trajectories for children in immigrant families in the United States. We used family socioeconomic status (SES) which considers parental education, parental occupation, and family income to define poverty in correspondence with the U.S.

Despite a large literature documenting the impact of childbearing on women's wages, less understanding exists of the actual employment trajectories that mothers take and the circumstances surrounding different paths. We use sequence analysis to chart the entire employment trajectory for a diverse sample of U.S.

Facing dramatic growth in its elderly population, Shanghai, China's economic center, has strategically exercised decentralized policy-making power to develop community-based service centers for the elderly. A growing number of elders have been using such services, particular dining services, since 2007. We discuss the evolution in community-based eldercare services in Shanghai, using dining services as an example.

In recent years, several OECD countries have taken steps to promote policies encouraging fathers to spend more time caring for young children, thereby promoting a more gender equal division of care work. Evidence, mainly for the United States and United Kingdom, has shown fathers taking some time off work around childbirth are more likely to be involved in childcare related activities than fathers who do not take time off. This paper conducts a first cross-national analysis on the association between fathers' leave taking and fathers' involvement when children are young.

This study investigates the trajectory of various dimensions of health status among the Chinese elderly in their late years. We used growth-curve analyses on a subsample (n≈2000) of the elderly from the Chinese Longitudinal Health Longevity Survey (CLHLS) who had longitudinal information from 1998 to 2005. Analyses controlled for a large set of individual and family characteristics.

Head Start includes family-oriented services to enhance parent-child relationships, but little is known about the effect of Head Start on parenting practices. Using data from the Early Childhood Longitudinal Study-Birth Cohort ( ≈ 7,000), we examined whether participation in Head Start was associated with maternal spanking, with particular attention to whether the association differed by child gender. We found that Head Start participation was associated with lower likelihood that mothers spanked their child in the past week at both preschool and kindergarten entry as well as lower likelihood that mothers would use spanking in a hypothetical situation, among boys but not girls.

This article draws upon the literature showing the benefits of high-quality preschools on child well-being to explore the role of household income on preschool attendance for a cohort of 3- to 6-year-olds in China using data from the China Health and Nutrition Survey, 1991-2006. Analyses are conducted separately for rural (N = 1,791) and urban (N = 633) settings. Estimates from a probit model with rich controls suggest a positive association between household income per capita and preschool attendance in both settings.

This study is the first to test whether receipt of a federal child care subsidy is associated with children of immigrants' school readiness skills. Using nationally representative data (n ≈ 2,900), this study estimates the associations between subsidy receipt at age 4 and kindergarten cognitive and social outcomes, for children of immigrant versus native-born parents. Among children of immigrants, subsidized center-based care (vs.

Using a sample of low-income children from the Early Childhood Longitudinal Study-Birth Cohort ( ≈ 4,350) and propensity-score weighted regressions, we analyzed children's nutrition, weight, and health care receipt at kindergarten entry, comparing 1) Head Start participants and all non-participants, and 2) Head Start participants and children in prekindergarten, other center-based care, other non-parental care, or only parental care. Overall, we found that compared to all non-participants, Head Start participants were more likely to receive dental checkups but showed no differences in getting medical checkups; they were also more likely to have healthy eating patterns but showed no differences in Body Mass Index (BMI), overweight, or obesity. However, these results varied depending on the comparison group-Head Start participants showed lower BMI scores and lower probability of overweight compared to those in other non-parental care, and the effects on healthy eating and dental checkups differed by comparison group.

This paper provides a comprehensive review of empirical evidence linking parental nonstandard work schedules to four main child developmental outcomes: internalizing and externalizing problems, cognitive development, and body mass index. We evaluated the studies based on theory and methodological rigor (longitudinal data, representative samples, consideration of selection and information bias, confounders, moderators, and mediators). Of 23 studies published between 1980 and 2012 that met the selection criteria, 21 reported significant associations between nonstandard work schedules and an adverse child developmental outcome.

Using data from the Early Childhood Longitudinal Study-Birth Cohort (n ≈ 6,950), a nationally representative sample of children born in 2001, we examined school readiness (academic skills and socioemotional well-being) at kindergarten entry for children who attended Head Start compared with those who experienced other types of child care (prekindergarten, other center-based care, other nonparental care, or parental care). Using propensity score matching methods and ordinary least squares regressions with rich controls, we found that Head Start participants had higher early reading and math scores than children in other nonparental care or parental care but also higher levels of conduct problems than those in parental care. Head Start participants had lower early reading scores compared with children in prekindergarten and had no differences in any outcomes compared with children in other center-based care.

Using data from the 1967-2009 years of the March Current Population Surveys (CPS), we examine two important resources for children's well-being: time and money. We document trends in parental employment, from the perspective of children, and show what underlies these trends. We find that increases in family work hours mainly reflect movements into jobs by parents-particularly mothers, who in prior decades would have remained at home.

This study investigates the link between the frequency of family breakfasts and dinners and child academic and behavioral outcomes in a panel sample of 21,400 children aged 5-15. It complements previous work by examining younger and older children separately and by using information on a large number of controls and rigorous analytic methods to discern whether there is causal relation between family meal frequency (FMF) and child outcomes. In child fixed-effects models, which controlled for unchanging aspects of children and their families, there were no significant (p<.

Using the Early Childhood Longitudinal Study-Birth Cohort (n ≈ 6,800), we examined the factors explaining variation in school readiness in a large and nationally representative sample of children in immigrant and non-immigrant families. In OLS regression models with rich controls to account for selection, we found that language background was a key factor in explaining children of immigrants' expressive language and early reading at kindergarten, whereas both socioeconomic status and language background helped explain their performance in math.

Child care and early education policies may not only raise average achievement but may also be of special benefit for less advantaged children, in particular if programs are high quality. We test whether high quality child care is equalizing using rich longitudinal data from two comparison countries, Denmark and the United States. In Denmark, we find that enrollment in high-quality formal care at age 3 is associated with higher cognitive scores at age 11.
