Reproducing inequalities: luck, wallets, and the enduring effects of childhood health

Early Childcare and Education in a Post-Industrial Landscape: Inequalities in Proximity to Active and Relic Manufacturing in Metropolitan Providence, Rhode Island

Children are uniquely vulnerable to environmental health risks associated with industrial contamination, and early childcare and education (ECE) facilities are important sites for potential exposure to environmental contaminants. Emerging research on historic urban industry has additionally demonstrated that urban environmental risk accumulates historically and spatially across urban landscapes. Accordingly, this study pairs cross-sectional data on licensed childcare facilities with longitudinal manufacturing site data in Providence, Rhode Island. We use these data to investigate the proximity of ECE facilities to active and relic manufacturing sites, controlling for a range of organizational- and tract-level characteristics. Results show that type of childcare facility (center-based vs. in-home) and language of instruction (Spanish vs. English) are important predictors of children's proximity to industrial lands, past and present. These findings indicate that Spanish-speaking children in Providence may experience a "double jeopardy" in the form of disproportionate legacy environmental hazards at ECE as well as at home-suggesting that the historical nature of urban industrial land use is an important mechanism of environmental inequality for young children.

Amplified disparities: The association between spousal education and own health

Positive associations between own educational attainment and own health have been extensively documented. Studies have also shown spousal educational attainment to be associated with own health. This paper investigates the extent to which spousal education contributes to the social gradient in health, net of own education; and whether parts of a seeming spousal education effect are attributable to differences in early-life human capital, as measured by respondents' height and childhood living standard. Furthermore, we investigate the relative contribution of predictors in the regression analysis by use of Shapley value decomposition. We use data from a comprehensive health survey from Northern Norway (conducted in 2015/16, N = 21,083, aged 40 and above). We apply three alternative health outcome measures: the EQ-5D-5L index, a visual analogue scale (EQ-VAS) and self-rated health. In all models considered, spousal education is generally positively significant for both men and women. The results also suggest that spousal education is generally more important for men than women. In the sub-sample of individuals having a spouse, decomposition analyses showed that the relative contribution of spousal education to the goodness-of-fit in men's (women's) health was 13% (14%) with the EQ-5D-5L; 25% (20%) with the EQ-VAS and; 30% (21%) with self-rated health. Heterogeneity analyses showed stronger spousal education effects in younger age groups. In conclusion, we have provided empirical evidence that spousal education may contribute to explaining the amplified health gradient in an egalitarian country like Norway.

The Long Shadow: Early-Life Adversity and Later-Life Loneliness in the United States

OBJECTIVES

This study assesses how early-life adversity (ELA) is associated with later-life loneliness among those aged 55 and older in the United States. We consider multiple domains of ELA to understand domain-specific associations between ELA and later-life loneliness.

METHODS

Using data from the 2008 to 2016 rounds of Health and Retirement Study (n = 29,661 person-waves [weighted]), we evaluate whether and how different domains of ELA are associated with loneliness, and how their relationships are explained through adulthood conditions and are dependent on educational attainment.

RESULTS

Our analyses demonstrate significant and distinctive relationships between various domains of ELA and later-life loneliness. Whereas adulthood conditions largely explain positive associations between loneliness with some domains of ELA (socioeconomic disadvantages and chronic diseases), disruptive home environment, risky adolescent behaviors, and impairment during childhood are still related to a higher level of loneliness after controlling for adulthood conditions. We also find empirical evidence supporting educational differences in relationships between some ELA domains and later-life loneliness. Our results also show that the associations between ELA and later-life loneliness differ between subdimensions of loneliness (emotional vs. social loneliness).

DISCUSSION

This study underscores ELA as an important early-life risk factor contributing to later-life loneliness. Our findings suggest that policy interventions to reduce adverse childhood experiences may alleviate individuals' exposure to loneliness in later life.

Childhood adversity and educational attainment: Evidence from Zambia on the role of personality

Introduction

We examine whether personality traits mediate the association between childhood adversity and educational attainment using longitudinal data from a cohort in Zambia.

Methods

We fit a structural equation model using data on three forms of childhood adversity-household poverty, stunting as a measure of chronic malnutrition, and death of a parent-and data on the "Big Five" personality traits and educational attainment assessed at 15 years of age.

Results

We find that childhood poverty and death of a parent are associated with lower openness to experience. Furthermore, openness to experience mediates 93% of the negative association between death of a parent and school enrollment and 19% of the negative association between childhood poverty and enrollment.

Discussion

Our findings reinforce a diverse and growing body of evidence linking childhood adversity to educational attainment while also placing it in a new light. Future work should continue to examine the biological and psychosocial pathways that determine openness to experience and other personality traits, as well as their role in shaping important life outcomes.

The reach of fertility decline: a longitudinal analysis of human capital gains across generations

The impact of fertility decline on economic development remains central to population studies. Recent scholarship emphasizes parental investment in education as a mediator. We further develop the theoretical foundation, and empirical evidence, for the role of child health—specifically how fertility changes promote children’s physical and cognitive development and thereby complement human capital accumulation through educational gains. We test this using a two-generation model applied to Indonesian longitudinal data from 1993 to 2015. Characteristics of modern fertility regimes—older maternal ages, longer interpregnancy intervals, and lower average birth orders—generally benefit offspring cognitive development and schooling. We estimate that family planning expansion, and the resulting shift in fertility traits, induced an average increase of 0.34 years of offspring educational attainment by age 18 years. Maximal maternal educational and family planning expansion would jointly produce a 1.12-year gain, including 0.20 years more directly attributable to fertility shifts. Evidence is strengthened in parallel simulations from models of within-mother shifts, in which fertility shifts resulted in a 0.16-year gain in offspring schooling. Findings contribute new evidence for the rounding effects of women’s education and family planning expansion on human capital formation through child health within families and across generations.

Perinatal Health Inequalities in the Industrial Region of Estonia: A Birth Registry-Based Study

Despite the increasing number of studies on industrially contaminated sites (ICS) and their health effects, there are very few studies on perinatal health outcomes in ICSs. In the present study, we examined the perinatal health inequalities by comparing adverse birth outcomes (ABOs) in the oil shale industry region of Ida-Viru County in Estonia with national-level figures and investigated the effects of maternal environmental and sociodemographic factors. Based on the 208,313 birth records from 2004-2018, Ida-Viru ICS has a birth weight 124.5 g lower than the average of 3544 g in Estonia. A higher prevalence of preterm birth (4.3%) and low birth weight (4.8%) in Ida-Viru ICS is found compared to 3.3% on both indicators at the national level. Multiple logistic regression analysis shows the statistically significant association of ABOs with fine particle (PM_2.5) air pollution, mother's ethnicity, and education throughout Estonia. However, in Ida-Viru ICS, the ABOs odds are remarkably higher in these characteristics except for the mother's ethnicity. Furthermore, the ABOs are associated with the residential proximity to ICS. Thus, the Ida-Viru ICS has unequally higher odds of adverse perinatal health across the environmental and sociodemographic factors. In addition to reducing the air pollutants, policy actions on social disparities are vital to address the country's unjustly higher perinatal health inequalities, especially in the Ida-Viru ICS.

The link between executive function, socio-emotional functioning and health-related quality of life in children and adolescents with mild to moderate chronic kidney disease

BACKGROUND

Children and adolescents with mild to moderate chronic kidney disease (CKD) are at high risk for mild but persistent impairment in executive functions, which have been associated with low health-related quality of life (HRQOL) among children and adolescents with chronic health conditions. However, no similar link has been established among children and adolescents with mild to moderate CKD. Given the essential role executive functions play in the development of adequate cognitive, emotional and social skills, it is essential to gain a clearer understating of the magnitude and attributes of executive functions and its link to HRQOL in order to inform appropriate medical and educational interventions for this patient population.

OBJECTIVE

The aim of this study is to examine the relationship between executive functions, socio-emotional functioning and HRQOL in children and adolescents with mild to moderate CKD.

METHODS

A cross-sectional design was used for this secondary data analysis of 199 children and adolescents (ages 6-17) with mild to moderate CKD from the United States and Canada who receive care at hospitals associated with the Chronic Kidney Disease in Children Study (CKiD).

RESULTS

The presence of impairment in executive functions and socio-emotional functioning (internalizing problems) significantly predicted lower HRQOL after controlling for key covariates (i.e., maternal education, anaemia and hypertension). Further, internalizing problems partially mediated the relationship between executive functions and HRQOL such that impairment in executive functions predicted lower HRQOL directly and indirectly by contributing to higher internalizing problems, which further contributed to low HRQOL.

CONCLUSION

This study underscores the importance of executive functions and socio-emotional functioning in the manifestation of HRQOL. Given that HRQOL is potentially compromised for many children and adolescents with mild to moderate CKD, it will be important for both clinicians and researchers to examine a range of factors, including executive functions and socio-emotional functioning, in order to optimize HRQOL.

The unequal consequences of family structures for infant health

Rapid changes in American families have reshaped inequalities in child well-being. This paper examines the unequal consequences of family structures for infant health, focusing on birthweight. Existing studies mainly address the average association between marriage (versus singlehood) and birthweight. I extend the literature by 1) explicitly considering cohabitation and 2) exploring the heterogeneous associations based on mother's likelihood of union formation at conception. Pooling nationally representative data from the National Survey of Family Growth 2011-17, I analyze a sample of recent births (N = 4,376) born to mothers aged between 20 and 49 years. Propensity score methods are used to address selections. Results show that 1) compared to single mothers, married mothers reap birthweight benefits, while cohabiting mothers do not; 2) married mothers with a higher likelihood to marry at conception (i.e., more advantaged) reap even larger birthweight benefits than their low-likelihood counterparts (i.e., less advantaged). Overall, the findings reveal important and nuanced roles of family structure in the reproduction of intergenerational inequality through infant health.

Evaluating the Role of Parental Education and Adolescent Health Problems in Educational Attainment

This article reconsiders the role of social origin in health selection by examining whether parental education moderates the association between early health and educational attainment and whether health problems mediate the intergenerational transmission of education. We used longitudinal register data on Finns born in 1986–1991 (n = 352,899). We measured the completion of secondary and tertiary education until age 27 and used data on hospital care and medication reimbursements to assess chronic somatic conditions, frequent infections, and mental disorders at ages 10–16. We employed linear probability models to estimate the associations between different types of health problems and educational outcomes and to examine moderation by parental education, both overall in the population and comparing siblings with and without health problems. Finally, we performed a mediation analysis with g-computation to simulate whether a hypothetical eradication of health problems would weaken the association between parental and offspring education. All types of health problems reduced the likelihood of secondary education, but mental disorders were associated with the largest reductions. Among those with secondary education, there was further evidence of selection to tertiary education. High parental education buffered against the negative impact of mental disorders on completing secondary education but exacerbated it in the case of tertiary education. The simulated eradication of health problems slightly reduced disparities by parental education in secondary education (up to 10%) but increased disparities in tertiary education (up to 2%). Adolescent health problems and parental education are strong but chiefly independent predictors of educational attainment.

Developing Health Lifestyle Pathways and Social Inequalities across Early Childhood

Lifestyles are a long-theorized aspect of social inequalities that root individual behaviors in social group differences. Although the health lifestyle construct is an important advance for understanding social inequalities and health behaviors, research has not theorized or investigated the longitudinal development of health lifestyles from infancy through the transition to school. This study documented children's longitudinal health lifestyle pathways, articulated and tested a theoretical framework of health lifestyle development in early life, and assessed associations with kindergarten cognition, socioemotional behavior, and health. Latent class analyses identified health lifestyle pathways using the US Early Childhood Longitudinal Study - Birth Cohort (ECLS-B; N≈6,550). Children's health lifestyle pathways were complex, combining healthier and unhealthier behaviors and changing with age. Social background prior to birth was associated with health lifestyle pathways, as were parents' resources, health behaviors, and non-health-focused parenting. Developing health lifestyle pathways were related to kindergarten cognition, behavior, and health net of social background and other parent influences. Thus, family context is important for the development of complex health lifestyle pathways across early childhood, which have implications for school preparedness and thus for social inequalities and well-being throughout life. Developing health lifestyles both reflect and reproduce social inequalities across generations.

Maternal human capital accumulation and children's well-being

Research examining the intergenerational transmission of human capital is subject to two limitations. First, for the parental generation, most studies focus on formal education but fail to consider vocational training experience, which has more variation than formal educational attainment over the life course. Second, most studies have found consistent conclusions using income and occupation for the children's outcomes but have generated mixed findings regarding health and cognitive ability. This study aims to answer whether mothers' additional vocational training beyond formal education is beneficial to children's health and cognitive ability. Applying fixed-effects regression to the National Longitudinal Survey of Youth 1979 and the National Longitudinal Survey of Youth Child and Young Adults datasets, this study finds that mothers' human capital accumulation is positively associated with higher cognitive scores for both boys and girls, but does not significantly predict children's illnesses or behavior problems. These findings bear implications for policy aimed at mitigating the intergenerational cycles of disadvantages.

Trajectories of physical functioning among older adults in the US by race, ethnicity and nativity: Examining the role of working conditions

Latinos in the US live significantly longer than non-Latino whites, but spend more years disabled. Differentials in socioeconomic status account for part, but not all, of the difference in older age disability between Latinos and whites. We hypothesize that a factor often ignored in the literature—the fact that Latinos, on average, have more physically strenuous jobs than non-Latino whites—contributes to the higher Latino risk of functional limitations at older ages. We use longitudinal data from the 1998–2014 Health and Retirement Study (HRS) comprising 17,297 respondents. Compared to US-born whites, Latinos, especially Latino immigrants, report substantially higher levels of physical effort at work. Latino-black differences are much smaller than Latino-white differences. As hypothesized, physical work effort is strongly related to functional limitations. However, differentials in physical work effort for Latinos and whites in their fifties and early sixties are weakly related to Latino-white differentials in FL at later ages.

Sibling mortality burden in low-income countries: A descriptive analysis of sibling death in Africa, Asia, and Latin America and the Caribbean

In high-income countries, emerging research suggests sibling bereavement can have significant health and life course consequences for young people. Yet, we know far less about its burden in lower-income countries. Due to higher fertility and mortality in lower-income countries, the level, timing, intensity, and circumstances surrounding sibling mortality are likely to follow patterns distinct from those in higher-income settings. Thus, in this study, we offer a descriptive overview of sibling death in 43 countries across sub-Saharan Africa, South and Southeast Asia, and Latin America and the Caribbean. Specifically, we analyze Demographic and Health Survey data from nationally representative samples of 352,930 15- to 34-year-old women, born between 1985 and 2003, to document experiences of sibling death before age 25. On average, roughly one-third of individuals report a deceased sibling in these countries; estimates reach 40-50% of respondents in multiple African countries, particularly those that have experienced conflict and war. Although some sibling deaths occurred before the focal respondent was born, most bereaved individuals recalled a death during their lifetime-often in late childhood/early adolescence. High proportions of bereaved respondents report multiple sibling deaths, highlighting the clustering of deaths within families. Even so, bereaved individuals tend to come from large families and thus frequently have a comparable number of surviving siblings as people who never experienced a sibling die. Together, the results offer a window into global inequality in childhood experiences, and they attest to the need for research that explores the implications of sibling mortality for young people in world regions where the experience is concentrated.

Working and disability expectancies at older ages: The role of childhood circumstances and education

The ability to work at older ages depends on health and education. Both accumulate starting very early in life. We assess how childhood disadvantages combine with education to affect working and health trajectories. Applying multistate period life tables to data from the Health and Retirement Study (HRS) for the period 2008-2014, we estimate how the residual life expectancy at age 50 is distributed in number of years of work and disability, by number of childhood disadvantages, gender, and race/ethnicity. Our findings indicate that number of childhood disadvantages is negatively associated with work and positively with disability, irrespective of gender and race/ethnicity. Childhood disadvantages intersect with low education resulting in shorter lives, and redistributing life years from work to disability. Among the highly educated, health and work differences between groups of childhood disadvantage are small. Combining multistate models and inverse probability weighting, we show that the return of high education is greater among the most disadvantaged.

Actor-Partner Effects of Childhood Disadvantage on Later Life Subjective Well-Being Among Individuals in Coresidential Unions

OBJECTIVES

Prior research on cumulative disadvantage has primarily focused on individuals' own childhood adversity for their later-life outcomes. Nevertheless, partner's childhood disadvantage may also shape respondent's later-life well-being.

METHODS

Drawing on a household-level dataset, I examine respondent's own childhood adversity as well as their partner's childhood adversity (poor childhood health, parental divorce, or father's long-term unemployment) on respondent's subjective well-being, at aged 50 and older.

RESULTS

Findings from the actor-partner interdependence model (APIM) show poor childhood health of the male partner as associated with worse mental health and self-rated health of the female partner in later life. For both outcome measures, the partner effects were attenuated after adjusting for the female partner's report of perceived social support. For self-rated health, adjusting for variation in the presence of a chronic illness and household income also attenuated the association.

DISCUSSION

Partnered individuals are nested within a specific context, whereby stress and implications of early life disadvantage may be conceptualized at the couple-level. Future research that assesses how early life experiences of individuals may have implications for family members' later-life well-being may be valuable.

Distance and acceptance: Identity formation in young adults with chronic health conditions

Health has long been a chief concern of life course researchers, especially in examining early life. Research on chronic conditions and their impact on individual identity often center on biographical disruption or the idea of a bifurcation of "before and after" identities. This research examines identity formation in young adults with chronic health conditions that began in childhood, a population that continues to grow. This study focuses on young adults' narrative identities, both regarding how young adults describe the transition to adulthood and how cultural ideals of young adulthood and actors from institutions influence how they describe themselves. This study uses 22 in-depth qualitative interviews to reveal how young adults distance themselves from their conditions or move to acceptance through the narratives they tell about their health, feelings, and behaviors. This research suggests that identity confirmation by others forms an integral part of the nexus of health and the life course, shaping how adolescents make the transition into young adulthood. Social support from actors in institutions gives room to some young adults with chronic conditions to integrate their conditions into their narrative identities. This study reveals the social nature of young adult identities, and how cultural ideals guide them, precisely because it uses cases of young adults who must transition to adulthood in alternative ways.

Family Arrangements and Children's Education Among Migrants: A Case Study of China

As China is experiencing an urban revolution with massive rural-to-urban migration, millions of children are profoundly affected by their parents' migration and their decision on family arrangement. With the discriminatory Hukou system and harsh living conditions in cities, the dilemma migrant parents face is whether they should bring children to cities or leave them behind. This decision determines the household, school and community environment children live in, which in turn shapes their wellbeing. With a unique strategy of comparing "left behind children" to "migrant children" and a gendered perspective, this paper examines how different family arrangements among migrants and consequent housing conditions and gender dynamics affect children's educational wellbeing. Our findings demonstrate the complex impact of family arrangement on children, which is conditioned on wage income and the gender of absent parent and the child. We find that children from less favorable socioeconomic backgrounds benefit more from moving to cities. Children living with both parents and those living with mother and grandparents tend to do better. While the effect of housing conditions is marginal, family arrangement has a gendered effect on children. Related policy recommendations are provided.

Widowhood and mortality: gender, race/ethnicity, and the role of economic resources

PURPOSE

We examine widowhood effects on mortality across gender and race-ethnicity, with attention to variation in the mediating role of economic resources.

METHODS

Data were drawn from the Health and Retirement Study (1992-2016). The analytic sample included 34,777 respondents aged 51 years and older who contributed 208,470 person-period records. Discrete-time hazard models were estimated to predict the odds of death among white men, black men, Hispanic men, white women, black women, and Hispanic women separately. The Karlson-Holm-Breen analysis was conducted to examine the mediating role of economic resources across groups.

RESULTS

Across all gender and racial-ethnic subgroups, widowhood effects on mortality were largest for Hispanic men. Black women and Hispanic women also suffered stronger effects of widowhood on mortality than white women. For both men and women, economic resources were an important pathway through which widowhood increased mortality risk for whites and blacks but not for Hispanics.

CONCLUSIONS

Findings highlight that gender and race-ethnicity intersect with widowhood status to disadvantage some groups more than others. It is important to explore the complex pathways that contribute to the higher mortality risk of racial-ethnic minorities, especially Hispanic men, after widowhood so that effective interventions can be implemented to reduce those risks.

Interpregnancy intervals and perinatal and child health in Sweden: A comparison within families and across social groups

A large body of research has shown that children born after especially short or long birth intervals experience an elevated risk of poor perinatal outcomes, but recent work suggests this may be explained by confounding by unobserved family characteristics. We use Swedish population data on cohorts born 1981-2010 and sibling fixed effects to examine whether the length of the birth interval preceding the index child influences the risk of preterm birth, low birth weight, and hospitalization during childhood. We also present analyses stratified by salient social characteristics, such as maternal educational level and maternal country of birth. We find few effects of birth intervals on our outcomes, except for very short intervals (less than seven months) and very long intervals (>60 months). We find few differences in the patterns by maternal educational level or maternal country of origin after stratifying by the mother's highest educational attainment.

Does Parents' Union Instability Disrupt Intergenerational Advantage? An Analysis of Sub-Saharan Africa

The long arm of childhood, with its wide-ranging influence on individuals' life chances, highlights the importance of understanding the determinants of health in early life. Research has established that parents' education is a major determinant of childhood health, but children across the globe increasingly experience their parents' divorce and subsequent remarriage, raising questions of whether union instability alters these intergenerational processes. Does divorce and remarriage interfere with parents' education benefiting their young children's health? I explore this question in sub-Saharan Africa, a world region where parents' education plays a major role in protecting children against severe health risks, and where young children commonly experience parental divorce and remarriage. Moreover, sub-Saharan Africa features distinct family lineage systems, affording an opportunity to explore this question in both majority matrilineal and patrilineal contexts. Analyses of Demographic and Health Survey data on 271,292 children in 30 sub-Saharan African countries offer no evidence that the high levels of union instability in the region will weaken the health benefits of parents' education for future generations. Following divorce, children benefit from their biological parents' education to the same degree as children with married parents-a finding that is consistent across lineage contexts. Moreover, stepfathers' education corresponds with pronounced health benefits for their coresident stepchildren, particularly in patrilineal regions where these children benefit less dramatically from their mothers' education. Together, the study results offer a renewed sense of the importance of parents'-including stepfathers'-education for early childhood health across diverse family structures.

Early-life social and health determinants of adult socioeconomic position: associations and trends across generations

Background

Social and biological circumstances at birth are established predictors of adult socioeconomic position (SEP). This study aims to assess the trends in these associations across two generations and examine the effects of parental early-life characteristics on descendants’ adult SEP.

Methods

We studied men and women born in the Uppsala University Hospital 1915–1929 (G1) and their offspring born 1932–1960 (G2). Data were collected in archives and routine registers. Adult SEP was assessed as an aggregate measure combining education and occupation. The exposures were family SEP, mother’s marital status, mother’s parity, mother’s age, standardised birth weight, gestational length and birth multiplicity. Linear regression was used to examine the associations across generations.

Results

The difference in adult SEP between low and high family SEP at birth was 15.8 (95% CI: 13.3 to 18.3) percentage points smaller in G2 compared with G1, although a considerable difference was still evident in G2. The associations of adult SEP with small birth weight for gestational age, post-term birth and high parity were stable between the generations: the generational differences in adjusted coefficients were 1.5 (95% CI: −1.1 to 4.1), 0.6 (–1.7 to 2.9) and 1.8 (–0.2 to 3.8) percentage points, respectively. The association between grandparental and grandchildren’s SEPs was largely explained by parental socioeconomic conditions. Father’s preterm birth was independently associated with offspring’s SEP.

Conclusion

The stability of the associations between early-life biological disadvantages and adult SEP and the persistent, although attenuated, association between early-life and adult SEPs necessitates increased policy attention to both social and health conditions at birth.

Early Poverty and Future Life Expectancy with Disability among the Elderly in Argentina: Pobreza Temprana y Esperanza de Vida Futura con Discapacidad entre los Adultos Mayores de la Argentina

Two aspects of the ageing process in Latin America should be specially taken into account in order to evaluate future perspectives of morbidity among the elderly in the region: 1) Cohorts who will compose the bulk of the elderly population in the 21st century in Latin America survived to old age largely because of improvements in medicine and to a much lesser extent to amelioration of living standards, as is the case in high income countries; 2) a high proportion of the Latin American population still live in poor economic conditions and even these vulnerable individuals continue to experience gains in (adult and older adult) survival. We aim to evaluate to what an extent recent levels of poverty and indigence among young children in Argentina could impact future levels of disability and demands for long-term care of older people. Our results show that given the levels of poverty and indigence in childhood observed between 1988 and 1994 and given the relationship between poor early conditions and the risk of being disabled among the elderly in Argentina, life expectancy with disability at age 60 old would increase substantially between 2000 and 2040 both in absolute and relative terms.

Finding Jobs, Forming Families, and Stressing Out? Work, Family, and Stress among Young Adult Women in the United States

The transition to adulthood is increasingly characterized by complex paths into the world of work and family, especially for young women. Yet how work and family combine to influence stress among young adult women is not well understood. Using data from the National Longitudinal Study of Adolescent to Adult Health, we leverage new extensions to latent class analysis (LCA) to identify common combinations of work and family circumstances among young adult women, their earlier life and contemporaneous correlates, and associations with two stress measures: a multi-item Perceived Stress Scale (PSS) and Epstein–Barr Viral (EBV) antibody titers, a well-validated biomarker of stress-related immunity impairments. We identify seven different common combinations of latent work–family combinations among young adult women ranging from well-compensated professional workers with and without children, mothers without paid employment, and delayed transitions to work and family. Completing a college degree was associated with a higher likelihood of membership in classes marked by professional work irrespective of motherhood, while being raised in a community with greater female labor opportunities was generally associated with membership in child-free classes. Mothers and child-free women in “pink-collar” work with low wages and decision-marking freedom reported higher stress compared to women in “white-collar” work with higher wages and decision-making freedom. These differences are mostly attenuated following adjustments for poverty-related stressors and work–family conflict. While prior work has emphasized the health benefits for women of combining work and family, our research suggests these benefits may be limited to women of higher socioeconomic status with flexible, well-compensated jobs.

The Educational Gradient in Health among Children in Immigrant Families

Educational inequality in the health of U.S. children-what social scientists refer to as the "educational gradient" in health-is present at birth for virtually every marker of health, and increases throughout childhood. However, a puzzling contradiction to this pattern has been observed among the growing population of youth in immigrant families. Some evidence suggests an ambiguous relationship between education and health among immigrant families, with a flat relationship between maternal education and maternal health behaviors and children's birth outcomes, and a stronger relationship as children become adolescents. Does an educational gradient in health emerge among children in immigrant families during childhood and adolescence? To date, we lack a prospective examination of how the gradient changes from birth throughout childhood and adolescence among this population. Moreover, while the dominant explanation for a weaker gradient among children with immigrant parents centers on the family setting, we know little about family-level dynamics among the same immigrant families as children age. Using national, longitudinal data from the Fragile Families and Child Well-Being Study, we examine the association between maternal education and children's health (measured by mothers' ratings) over the early life course (birth through age 15) among children of immigrants and children of native-born parents, and consider whether changes in children's economic status and family composition contribute to the educational gradient, or lack thereof, in child health. Analyses reveal that: (1) maternal education is strongly predictive of health, even among children of immigrants; (2) immigrant status does not appear to be protective for health within educational groups, as evidenced by poorer health among children of immigrants whose mothers have the lowest level of education, as compared to children of natives; (3) children in the least-educated immigrant families are experiencing better health trajectories as they age than children in similar native-born families; and (4) accounting for economic conditions and family composition does not reduce the size of the gradient over time.

Caesarean section and children's health: A quasi-experimental design

The prevalence of inflammatory child health conditions-such as asthma, eczema, and food allergy-and their associated costs have increased rapidly over the last 30 years. While environmental factors likely underpin these increases, recent studies explain only a fraction of the trend and rely on associational methods. Caesarean (or C-) section rates increased dramatically in the period of interest, and this method of delivery is an understudied environmental factor linked to child health outcomes via the gut microbiome. We fuse 22 years of birth cohort data from the United States National Surveys of Children's Health with C-section rates from the National Vital Statistics System generated for subgroups based on state, sex, race, Hispanic origin, and birth year. Then, we model the effects of C-section on rates of asthma, eczema, and food allergy using a quasi-experimental fixed effects design. We find that C-section significantly predicts food allergy, with qualitatively significant implications.

Low birth weight and childhood health: the role of maternal education

PURPOSE

Low birth weight (LBW) is associated with myriad health and developmental problems in childhood and later in life. Less well-documented is the variation in the relationship between LBW status and subsequent child health by socioeconomic status-such as education levels and income. This article examines whether differences exist in the relationship between LBW and subsequent child health by maternal education.

METHODS

We used data from the 1998-2017 National Health Interview Survey to estimate multivariate logistic regression models to determine whether the association between LBW and subsequent child health as measured by general health status, developmental disability, and asthma diagnosis differed by maternal education, net of differences in children's sociodemographic factors, family background, and medical access.

RESULTS

The negative association between LBW and subsequent health was typically weaker for children of mothers with less than high school education than it was for children of mothers with higher levels of education.

CONCLUSIONS

The findings on the enduring impact of LBW status on child health for all children, especially those born to mothers with higher levels of education, suggest that all children born LBW should be provided appropriate medical and support services to reduce the lifelong repercussions of poor health at birth.

The Scarring Effects of Father's Unemployment? Job-Security Satisfaction and Mental Health at Midlife

Objectives

We investigate the association between early-life paternal unemployment and midlife mental health, examining whether the impact of father's unemployment may vary contingent on the broader economic context on which it occurred. We also investigate job-security satisfaction as a potential mediator of this association.

Method

We utilize random-effects models, drawing on 15 waves of data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey, with 7,438 individuals and 42,309 individual-time observations.

Results

We find respondents whose father was unemployed report worse mental health at midlife (-2.27; p < .01), with the association being modest, though statistically significant. This association is also stronger for younger respondents, whose paternal unemployment was more likely during the economic downturn of the mid 1970s in Australia. Paternal unemployment is also associated with lower satisfaction with job security at midlife (-0.17; p < 0.05), which is related to worse mental health; however, it explains little of the association between paternal unemployment and mental health.

Discussion

Existing research finds paternal unemployment relates to educational attainment, socioeconomic achievement, and wellbeing in the shorter term, but exposure to this event may also have enduring implications for the wellbeing of the offspring.

How Lifestyle Factors Affect Cognitive and Executive Function and the Ability to Learn in Children

In today's research environment, children's diet, physical activity, and other lifestyle factors are commonly studied in the context of health, independent of their effect on cognition and learning. Moreover, there is little overlap between the two literatures, although it is reasonable to expect that the lifestyle factors explored in the health-focused research are intertwined with cognition and learning processes. This thematic review provides an overview of knowledge connecting the selected lifestyle factors of diet, physical activity, and sleep hygiene to children's cognition and learning. Research from studies of diet and nutrition, physical activity and fitness, sleep, and broader influences of cultural and socioeconomic factors related to health and learning, were summarized to offer examples of research that integrate lifestyle factors and cognition with learning. The literature review demonstrates that the associations and causal relationships between these factors are vastly understudied. As a result, current knowledge on predictors of optimal cognition and learning is incomplete, and likely lacks understanding of many critical facts and relationships, their interactions, and the nature of their relationships, such as there being mediating or confounding factors that could provide important knowledge to increase the efficacy of learning-focused interventions. This review provides information focused on studies in children. Although basic research in cells or animal studies are available and indicate a number of possible physiological pathways, inclusion of those data would distract from the fact that there is a significant gap in knowledge on lifestyle factors and optimal learning in children. In a climate where childcare and school feeding policies are continuously discussed, this thematic review aims to provide an impulse for discussion and a call for more holistic approaches to support child development.

Local Social Inequality, Economic Inequality, and Disparities in Child Height in India

This study investigates disparities in child height-an important marker of population-level health-among population groups in rural India. India is an informative context in which to study processes of health disparities because of wide heterogeneity in the degree of local segregation or integration among caste groups. Building on a literature that identifies discrimination by quantifying whether differences in socioeconomic status (SES) can account for differences in health, we decompose height differences between rural children from higher castes and rural children from three disadvantaged groups. We find that socioeconomic differences can explain the height gap for children from Scheduled Tribes (STs), who tend to live in geographically isolated places. However, SES does not fully explain height gaps for children from the Scheduled Castes (SC) and Other Backward Classes (OBCs). Among SC and OBC children, local processes of discrimination also matter: the fraction of households in a child's locality that outrank her household in the caste hierarchy predicts her height. SC and OBC children who are surrounded by other lower-caste households are no shorter than higher-caste children of the same SES. Our results contrast with studies from other populations where segregation or apartheid are negatively associated with health.

Health Status and Transitions in Cohabiting Relationships of American Young Adults

OBJECTIVE

This study examines whether individual health predicts cohabitors' union transitions to marriage in American young adults.

BACKGROUND

Associations between health and subsequent marital transitions are well documented, but less is known about how health influences transitions of cohabiting relationships. As cohabitation has become a common relationship experience, understanding how health may influence cohabitors' union transitions is an important component of how health shapes relationship exposures more broadly.

METHOD

Data were taken from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (http://www.cpc.unc.edu/projects/addhealth), including the supplemental collection of relationship partners conducted during Wave III. Competing risk regressions for the transition of cohabiting unions to marriage were estimated in two samples: one of individuals and a smaller one of cohabiting couples with information from both partners.

RESULTS

Healthier cohabiters are more likely to marry than are their less healthy counterparts, but only women's health is significantly associated with the transition to marriage. In the dyadic sample with information from both partners, the significant association between the female partner's health and the transition to marriage is robust to male partner characteristics, including health.

CONCLUSION

Health is an important predictor of cohabitation transitions in early adulthood, but these transitions may only be sensitive to the female partner's health.

Experience of Poverty and Problem Sleep in Later Life

Older adults are more likely to report problem sleep, but little is known about how the economic challenges of old age affect sleep. Using data from the disability and use of time from the panel study of income dynamics (N = 1,693), this study applied propensity score methods and the marginal structural model to estimate the associations between exposure to poverty and two measures of problem sleep: risky sleep duration and difficulty falling asleep. Poverty, irrespective of duration of exposure, had little impact on short sleep duration. Exposure to poverty, however, was associated with increased likelihood of long sleep duration on weekends and having difficulty falling asleep on both weekdays and weekends, especially for older adults who were exposed to poverty for 5 or more years. Findings suggest that economic hardship of old age may be a social structural obstacle for healthy sleep.

Prenatal Exposure to an Acute Stressor and Children's Cognitive Outcomes

Exposure to environmental stressors is highly prevalent and unequally distributed along socioeconomic lines and may have enduring negative consequences, even when experienced before birth. Yet, estimating the consequences of prenatal stress on children's outcomes is complicated by the issue of confounding (i.e., unobserved factors correlated with stress exposure and with children's outcomes). I combine a natural experiment-a strong earthquake in Chile-with a panel survey to capture the effect of prenatal exposure on acute stress and children's cognitive ability. I find that stress exposure in early pregnancy has no effect on children's cognition among middle-class families, but it has a strong negative influence among disadvantaged families. I then examine possible pathways accounting for the socioeconomic stratification in the effect of stress, including differential exposure across socioeconomic status, differential sensitivity, and parental responses. Findings suggest that the interaction between prenatal exposures and socioeconomic advantage provides a powerful mechanism for the intergenerational transmission of disadvantage.

The scars of the past? Childhood health and health differentials in later life

This study estimates multilevel mixed effects models of three retrospective measures of childhood health – self-rated childhood health, exposure to parental smoking growing up, and missing school for 30 or more consecutive days due to a health event – on levels and changes in physical functioning at age 50 and beyond. Using data from 15 waves of the Household, Income and Labour Dynamics in Australia survey, the results show that variation in the level of later-life physical functioning is associated with childhood health. Poor childhood health however is not associated with the rate of physical functioning decline. Respondents who reported poor childhood health and were migrants to Australia from a non-English speaking country reported better physical functioning in later life, compared with non-Indigenous Australian-born respondents who reported poor childhood health. In contrast, women who reported poor self-rated childhood health reported worse physical functioning compared with men who reported poor self-rated childhood health. These findings are robust to the inclusion of a range of measures of childhood and adult characteristics and circumstances. These results suggest that Australia, with arguably a strong and supportive health care system as compared with the U.S., may mitigate the accumulation of disadvantages to those who reported poor childhood health. We note that though functional health differences due to childhood health are not exacerbated in later life, neither are they eliminated.

•

Poor childhood health is associated with worse physical functioning in later life.

•

This association is stronger for women, as compared with men.

•

Association weaker for migrants non-English speaking countries, vs. native-born.

Race/ethnic inequalities in early adolescent development in the United Kingdom and United States

BACKGROUND

Comparative literature investigating race/ethnic patterning of children's health has found racial/ethnic minority status to be linked to health disadvantages. Less is known about differences during early adolescence, a period during which health outcomes are linked to later life health.

OBJECTIVE

Using the UK Millennium Cohort Study (n = 10,188) and the US Early Childhood Longitudinal Survey-Kindergarten Cohort (n ~ 6,950), we examine differences in socioemotional and cognitive development among 11-year-old adolescents and the contribution of family resources in explaining any observed differences, including socioeconomic, cultural traditions, and psychosocial resources.

RESULTS

Adverse socioemotional health and cognitive development were associated with race/ethnic minority status in both countries. In the United States, we found that cultural resources and family socioeconomic capital played a large role in attenuating differences in problem behaviors between Asian American, Black, and Latino adolescents and their White peers. In the United Kingdom, the explanatory factors explaining differences in problem behaviors varied by racial/ethnic group. In both contexts, family resources cannot explain the sizable cross-country differences in verbal skills. In the United Kingdom, Indian adolescents had nearly one-third of a standard deviation increase in their verbal scores whereas in the United States, Black and Latino adolescents had scores nearly two-fifths and one-fifth of a standard deviation below the mean, respectively.

CONTRIBUTION

We use a detailed race/ethnic classification in the investigation of racial/ethnic inequalities across the United States and United Kingdom. There are strong family resource effects, suggesting that relative family advantages and disadvantages do have meaningful associations with adolescent socioemotional and cognitive development. Although levels of resources do explain some cross-national differences, there appears to be a broader range of family background variables in the United Kingdom that influence adolescent development. Our findings point to the critical role of both the extent and nature of family social capital in affecting adolescent development.

Comparing Observed and Unobserved Components of Childhood: Evidence From Finnish Register Data on Midlife Mortality From Siblings and Their Parents

In this study, we argue that the long arm of childhood that determines adult mortality should be thought of as comprising an observed part and its unobserved counterpart, reflecting the observed socioeconomic position of individuals and their parents and unobserved factors shared within a family. Our estimates of the observed and unobserved parts of the long arm of childhood are based on family-level variance in a survival analytic regression model, using siblings nested within families as the units of analysis. The study uses a sample of Finnish siblings born between 1936 and 1950 obtained from Finnish census data. Individuals are followed from ages 35 to 72. To explain familial influence on mortality, we use demographic background factors, the socioeconomic position of the parents, and the individuals' own socioeconomic position at age 35 as predictors of all-cause and cause-specific mortality. The observed part-demographic and socioeconomic factors, including region; number of siblings; native language; parents' education and occupation; and individuals' income, occupation, tenancy status, and education-accounts for between 10 % and 25 % of the total familial influence on mortality. The larger part of the influence of the family on mortality is not explained by observed individual and parental socioeconomic position or demographic background and thus remains an unobserved component of the arm of childhood. This component highlights the need to investigate the influence of childhood circumstances on adult mortality in a comprehensive framework, including demographic, social, behavioral, and genetic information from the family of origin.

Health problems during childhood and school achievement: Exploring associations between hospitalization exposures, gender, timing, and compulsory school grades

Aims

To investigate while accounting for health at birth 1) associations between health problems during childhood, measured as hospitalizations, and school achievement in the final year of compulsory school, measured as overall grade points and eligibility for upper secondary education, 2) if and how gender moderates the association between health problems and school achievement, 3) if and how the timing of a health problem during childhood is associated with later school achievement.

Methods

Analyzes were performed on a population-based cohort (n = 115 196) born in 1990 in Sweden (51.3% boys, 48.7% girls) using data from several national registries. Multiple linear regression and logistic regression were used to analyze associations between study variables.

Results

Overall grade points and eligibility for continuation to upper secondary school were lower for individuals exposed to hospitalizations. Only the association between hospitalizations and overall grade points was moderated by gender and only for ages 13–16 years. Exposure close to actual grading had worst outcomes.

Conclusions

Health problems, measured through hospitalizations, was significantly associated with lower school achievements among Swedish children. Girls exposed to health problems requiring hospitalizations had relatively poorer school achievements as compared to boys. Health problems requiring hospitalization during junior high school had the greatest negative association with final achievement at compulsory school.

The Health Consequences of Social Mobility in Contemporary China

Although numerous studies have shown the importance of an individual’s socioeconomic status on his or her self-rated health status, less well-known is whether self-perceived class mobility, a measure highly correlated with an individual’s de facto social class and past mobility experiences, affects self-rated health. In this paper, we attempt to fill the gap by examining how perception of class mobility is associated with self-rated health. Using eight waves of Chinese General Social Survey data spanning the years 2005 to 2015, we conducted an analysis at the micro (individual) level and the macro (provincial) level. Analyses at both levels yielded consistent results. At the individual level, we employed ordered logistic regression and found that the perception of experiencing downward mobility was associated with significantly lower self-rated health in both rural and urban areas compared with those who consider themselves to be upwardly mobile or immobile. At the provincial level, the findings from static panel analysis further revealed that there is a positive relationship between the self-perceived class mobility and self-rated health level.

Smoking and Variation in the Hispanic Paradox: A Comparison of Low Birthweight Across 33 US States

The Hispanic Paradox in birth outcomes is well documented for the US as a whole, but little work has considered geographic variation underlying the national pattern. This inquiry is important given the rapid growth of the Hispanic population and its geographic dispersion. Using birth records data from 2014 through 2016, we document state variation in birthweight differentials between US-born white women and the three Hispanic populations with the largest numbers of births: US-born Mexican women, foreign-born Mexican women, and foreign-born Central and South American women. Our analyses reveal substantial geographic variation in Hispanic immigrant-white low birthweight disparities. For example, Hispanic immigrants in Southeastern states and in some states from other regions have reduced risk of low birthweight relative to whites, consistent with a "Hispanic Paradox." A significant portion of Hispanic immigrants' birthweight advantage in these states is explained by lower rates of smoking relative to whites. However, Hispanic immigrants have higher rates of low birthweight in California and several other Western states. The different state patterns are largely driven by geographic variation in smoking among whites, rather than geographic differences in Hispanic immigrants' birthweights. In contrast, US-born Mexicans generally have similar or slightly higher odds of low birthweight than whites across the US. Overall, we show that the Hispanic Paradox in birthweight varies quite dramatically by state, driven by geographic variation in low birthweight among whites associated with white smoking disparities across states.

The value of education to health: Evidence from Ireland

Does education have a causal impact on health? The existing literature presents mixed results. More evidence is required from contexts that have not been explored in the literature, and using clinically-measured health outcomes. Using data from the Irish Longitudinal Study on Ageing (TILDA), and exploiting a policy change in the 1960s that eliminated public secondary school fees, we investigate whether additional years of schooling for those with lower socio-economic status (SES) have a causal effect on the prevalence of cardiovascular disease in later life. We find significant sizable effects of education on the prevalence of both hypertension and diabetes. An additional year of schooling decreases the probability of having hypertension by approximately 3% points, and decreases the probability of having diabetes by approximately 1% point, effects that are large given existing prevalence. Further analysis of possible mechanisms shows that additional schooling increases the probability of engaging in high levels of physical activity and refraining from smoking. In the context of an increasing focus on strategies to prevent chronic disease, evidence such as this provides important insights for policymakers tasked with designing public health interventions targeting risk factors for chronic disease.

Heterogeneity of Hepatitis B Infection Among Pregnant Asian American and Pacific Islander Women

INTRODUCTION

Perinatal transmission of hepatitis B virus among Asian Americans and Pacific Islanders is a key driver of racial health disparities in liver cancer and mortality in the U.S. This study documents the prevalence of hepatitis B virus infection among pregnant women across racial/ethnic groups and among Asian Americans and Pacific Islanders to assess the need for intervention, and then identifies the individual correlates of hepatitis B virus infection among Asian American and Pacific Islander pregnant women.

METHODS

Using the 2014-2015U.S. birth rate population data, this study estimates a series of logistic regression models to examine the associations between individual-level correlates and hepatitis B virus infection among Asian American and Pacific Islanders pregnant women. Data were analyzed in July 2017.

RESULTS

Among Asian American and Pacific Islander pregnant women, Chinese American mothers are ten times more likely to experience hepatitis B virus infection than are Asian Indian and Japanese American mothers. Foreign-born mothers are significantly more likely to experience hepatitis B virus infection during pregnancy than those of their U.S.-born counterparts. Maternal SES characteristics are important correlates of hepatitis B virus infection among pregnant women.

CONCLUSIONS

Studies must disaggregate the pan-ethnic Asian American and Pacific Islander category to examine the health and health disparities of Asian Americans and Pacific Islanders. Given the heterogeneity of hepatitis B virus infection prevalence among Asian American and Pacific Islander pregnant women, the effectiveness of prevention and intervention programs depends on careful consideration of ethnicity in conjunction with group-specific factors.

Promoting health equity to prevent crime

Traditionally, research activities aimed at diminishing health inequalities and preventing crime have been conducted in isolation, with relatively little cross-fertilization. We argue that moving forward, transdisciplinary collaborations that employ a life-course perspective constitute a productive approach to minimizing both health disparities and early delinquent involvement. Specifically, we propose a multidimensional framework that integrates findings on health disparities and crime across the early life-course and emphasizes the role of racial and socioeconomic disparities in health. Developing the empirical nexus between health disparities research and criminological research through this multidimensional framework could fruitfully direct and organize research that contributes to reductions in health inequalities and the prevention of crime during the early life course. We also propose that this unified approach can ultimately enhance public safety policies and attenuate the collateral consequences of incarceration.

Do rising tides lift all boats? Racial disparities in health across the lifecourse among middle-class African-Americans and Whites

Although racial inequalities in health are well documented, much less is known about the underlying mechanisms that create and sustain these population patterns, especially among nonpoor subgroups. Using 20 waves of data from the Panel Study of Income Dynamics (PSID), we estimate the magnitude of the Black/White gap in self-rated health among middle-income, working-age (18–65) adults and explore potential sources of this disparity. Findings from multilevel regression models suggest that intragenerational gains in family income result in significantly smaller improvements in self-rated health for middle-class African-Americans than similarly situated Whites. We also note that childhood disadvantage predicts subsequent health trajectories in adulthood, but does little to explain the Black/White gap in the association between family income and self-rated health. We conclude that middle-class status provides restricted health returns to upward mobility for African-Americans and this differential relationship cannot be accounted for by greater exposure to early life disadvantage.

•

We use 20 waves of data to investigate lifecourse fluctuations in health among middle-class Americans.

•

Results suggest intragenerational mobility is associated with nonequivalent health outcomes across race.

•

For Whites, a 10% increase in family income over time reduces the odds of being in fair/poor health by 9.7%.

•

For Blacks, similar increases in family income resulted in significantly smaller reductions in the odds of fair or poor health.

•

This racial disparity cannot be explained by differential exposure to childhood socioeconomic disadvantage.

Integrating Biomarkers in Social Stratification and Health Research

This article provides an overview of the integration of biomarkers and biological mechanisms in social science models of stratification and health. The goal in reviewing this literature is to highlight research that identifies the social forces that drive inequalities over the life course and across generations. The article is structured in the following way. First, descriptive background information on biomarkers is presented, followed secondly by a review of the general theoretical paradigms that lend themselves to an integrative approach. Third, the biomarkers used to capture several biological systems that are most responsive to social conditions are described. Fourth, research that explicates how social exposures "get under the skin" to affect physiological functioning and downstream health is discussed, using socioeconomic disadvantage as an illustrative social exposure. The review ends with emerging directions in the use of biomarkers in social science research. This article endeavors to encourage sociologists to embrace biosocial approaches in order to elevate the importance of social factors in biomedical processes and to intervene on the social conditions that create inequities.
