Death of family members as an overlooked source of racial disadvantage in the United States.

Long-standing racial differences in US life expectancy suggest that black Americans would be exposed to significantly more family member deaths than white Americans from childhood through adulthood, which, given the health risks posed by grief and bereavement, would add to the disadvantages that they face. We analyze nationally representative US data from the National Longitudinal Study of Youth (n = 7,617) and the Health and Retirement Study (n = 34,757) to estimate racial differences in exposure to the death of family members at different ages, beginning in childhood. Results indicate that blacks are significantly more likely than whites to have experienced the death of a mother, a father, and a sibling from childhood through midlife. From young adulthood through later life, blacks are also more likely than whites to have experienced the death of a child and of a spouse. These results reveal an underappreciated layer of racial inequality in the United States, one that could contribute to the intergenerational transmission of health disadvantage. By calling attention to this heightened vulnerability of black Americans, our findings underscore the need to address the potential impact of more frequent and earlier exposure to family member deaths in the process of cumulative disadvantage.

Breastfeeding, overweight status, and inflammation.

Research documents a host of health benefits of breastfeeding for infants and children, including long-term health conditions arising from inflammation. Here, we provide new evidence about this association, focusing on the link between breastfeeding in infancy and inflammation in early adulthood. Our study is based on the National Longitudinal Study of Adolescent to Adult Health (Add Health) which allows us investigate a potentially important mediating pathway - overweight status from early adolescence into young adulthood. Results from pathway analyses in a structural equation modeling framework indicate that, in addition to a direct pathway linking breastfeeding and inflammation, an indirect pathway through overweight status across adolescence into young adulthood partially explains the association between breastfeeding and inflammation. Overweight status, moreover, links breastfeeding to inflammation not only through proximal timing of overweight status, but also through an indirect cascading process of overweight status over the life course that is evident in adolescence. Overall, this study highlights the importance of considering breastfeeding, overweight status and inflammation as dynamic life course processes that contribute to development of health inequalities.

Concentrated Poverty in U.S. Schools and Adolescents' Risk of Being Overweight.

The economic segregation of U.S. schools undermines the academic performance of students, particularly students from low-income families who are often concentrated in high-poverty schools. Yet it also fuels the reproduction of inequality by harming their physical health. Integrating research on school effects with social psychological and ecological theories on how local contexts shape life course outcomes, we examined a conceptual model linking school poverty and adolescent students' weight. Applying multilevel modeling techniques to the first wave of data (1994-1995) from the National Longitudinal Study of Adolescent to Adult Health (Add Health; n = 18,924), the results revealed that individual students' likelihood of being overweight increased as the concentration of students from low-income families in their schools increased, net of their own background characteristics. This linkage was connected to a key contextual factor: the exposure of students in high-poverty schools to other overweight students. This exposure may partly matter because of the lower prevalence of dieting norms in such schools, although future research should continue to examine potential mechanisms.

The Interplay of Peer, Parent, and Adolescent Drinking.

OBJECTIVE: To explore variability in the link between peer and adolescent drinking by parental drinking. Stress and differential susceptibility perspectives led to hypotheses that adolescents with drinking parents would be more reactive to peer drinking but also to peer abstention. METHODS: Using data from the National Longitudinal Study of Adolescent to Adult Health, regressions estimated whether the association between peer alcohol use and increased drinking among adolescents was moderated by parental drinking. A regions of significance test identified the level of peer drinking that predicted adolescent drinking in the context of parental drinking. RESULTS: Adolescents with binge-drinking parents were more likely to increase drinking at every level of peer drinking, supporting the stress perspective; such adolescents did not accrue benefits from abstaining peers, going against the differential susceptibility perspective. CONCLUSIONS: Far from monolithic, peer influences on adolescent risky behaviors may require family environments and genetic predispositions conducive to those behaviors.

Moving up, feeling down: socioemotional health during the transition into college.

Moving from high school to college is a critical juncture in socioemotional health, and how young people fare likely depends on their academic settings and experiences. To examine variation in trajectories of depressive symptomatology among a sample of US youth who transition from high school into college, this study applied growth mixture modeling to data from the National Longitudinal Study of Adolescent to Adult Health, which revealed multiple patterns of symptomatology over time that ranged from healthy to unhealthy. Adolescents appeared to have the healthiest trajectories when they experienced consistently competitive academic settings in high school and college. Overall, transitioning into college was a period of socioemotional vulnerability for some and wellbeing for others, but challenging curricula and contexts across this transition could differentiate between the two.

Are You Still Bringing Me Down?: Romantic Involvement and Depressive Symptoms from Adolescence to Young Adulthood.

Romantic involvement and mental health are dynamically linked, but this interplay can vary across the life course in ways that speak to the social and psychological underpinnings of healthy development. To explore this variation, this study examined how romantic involvement was associated with trajectories of depressive symptomatology across the transition between adolescence and young adulthood. Growth mixture modeling of data from the National Longitudinal Study of Adolescent to Adult Health identified trajectories of depressive symptomatology as teens grew into their late 20s and early 30s ( N = 8,712). Multinomial logistic techniques regressed these trajectories on adolescent and young adult romantic experiences. Adolescent dating was associated with increased depressive symptoms early on, particularly for girls, but this risk faded over time. For both boys and girls, trajectories of decreasing symptoms were associated with young adult unions but also the coupling of adolescent dating with young adult singlehood.

Gender and Health Behavior Clustering among U.S. Young Adults.

U.S. trends in population health suggest alarming disparities among young adults, who are less healthy across most measureable domains than their counterparts in other high-income countries; these international comparisons are particularly troubling for women. To deepen our understanding of gender disparities in health and underlying behavioral contributions, we document gender-specific clusters of health behavior among U.S. young adults using nationally representative data from the National Longitudinal Study of Adolescent to Adult Health. We find high levels of poor health behavior, but especially among men; 40 percent of men clustered into a group characterized by unhealthy behavior (e.g., poor diet, no exercise, substance use), compared to only 22 percent of women. Additionally, women tend to age out of unhealthy behaviors in young adulthood more than men. Further, we uncover gender differences in the extent to which sociodemographic position and adolescent contexts inform health behavior clustering. For example, college education was more protective for men, whereas marital status was equally protective across gender. Parental drinking mattered for health behavior clustering among men, whereas peer drinking mattered for clustering among women. We discuss these results in the context of declining female advantage in U.S. health and changing young adult social and health contexts.
