Policy interest in parental involvement in the U.S. has rapidly grown, necessitating a deeper understanding of how families and schools can partner to promote learning and reduce performance disparities in this country. Matching multidisciplinary theory with growth curve analyses of American children in the Early Childhood Longitudinal StudyKindergarten Cohort, this study found that familyschool engagement (in which school personnel and parents reached out to each other) and familyschool symmetry (in which parents and teachers constructed parallel learning environments) were associated with greater reading gains during the primary grades. Socioeconomically disadvantaged children appeared more at risk from one-sided engagement, and their more advantaged peers appeared to benefit more from symmetry.

To investigate the role of body size in social networks, this study estimated cross-nested multilevel network models (p2) with longitudinal data from

Drawing on time use data from the Child Development Supplement of the Panel Study of Income Dynamics, this study identified five different profiles of shared time between parents and young people at different stages of development. In childhood, all profiles had high rates of shared television viewing, but some were oriented toward in‐home activities and others toward activities outside the home (e.g., cultural events). These latter profiles tended to be higher in socioeconomic advantage, and the young people in them tended to demonstrate greater gains in math, but not reading, achievement across the transition into adolescence. In adolescence, shared activity profiles favored low amounts of shared time between parents and adolescents across activities and disfavored shared time in public domains.

Peer relations are central to adolescent life and, therefore, are crucial to understanding adolescents' engagement in various behaviors. In recent years, public health research has increasingly devoted attention to the implications of peer relations for the kinds of adolescent behaviors that have a direct impact on health. This article advocates for a continuation of this trend. With this aim, we highlight key themes in the rich literature on the general developmental significance of adolescent–peer relations, provide an overview of how these themes have been incorporated into public health research and practice, and suggest future avenues for peer-focused public health research that can inform adolescent health promotion in the United States.

Girls have caught up with boys in math course taking in high school but reasons for taking math still differ by gender. This study, therefore, investigated gender differences in the linkage between peer relations and math course taking by applying multilevel modeling to a nationally representative data set that includes peer networks and school transcripts (N= 6,457 American 9th to 11th graders, aged 13–19). For all adolescents, math course taking was associated with the achievement of their close friends and, to a lesser extent, their coursemates. These associations tended to be stronger toward the end of high school and weaker among adolescents with a prior record of failure in school. Each of these patterns was somewhat more consistent among girls.

Working from a life course perspective, this study examined the paradoxical association between academic status and drinking across the transition to young adulthood with multilevel modeling and a nationally representative sample of young people from the Add Health data project (n = 6,308). Taking academically advanced courses in high school was associated with lower rates of current drinking and binge drinking during high school (grades 9–12) but higher rates of both after high school (age range: 20–26). This positive longitudinal association between academic status and drinking was explained partly, but not completely, by educational, family, and work circumstances in young adulthood. The association was less likely to occur among students who attended high schools in which high achievement was the norm. Thus, the association between academic status and drinking behavior reverses across the transition to young adulthood, especially in certain types of peer environments within the educational system.

Obesity is a health condition, but its consequences extend far beyond the realm of health. To illuminate an important route by which the experience of obesity can filter into the status attainment process, this study drew on nationally representative data from the National Longitudinal Study of Adolescent Health to test a social psychological model of the gendered link between obesity and education. Obese girls were less likely to enter college after high school than were their nonobese peers, especially when they attended schools in which obesity was relatively uncommon. Additional analyses revealed that increasing rates of internalizing symptoms, self-medication, and academic disengagement explained about one-third of the obese girls' lower odds of college enrollment. Obese boys, on the other hand, did not differ from their peers—no matter what their school context—in college enrollment.

Given the increasing importance of education to socioeconomic attainment and other life course trajectories, early academic struggles can have long-te

The socioeconomic stratification of American society profoundly influences how the life course unfolds by shaping various developmental pathways as well as the connections among these pathways. Drawing on a nationally representative sample of American adolescents, this study charted trajectories of personal control and parental consultation from middle school to the end of high school and then examined how various combinations of these trajectories were associated with math/science course taking in high school across socioeconomic strata. Results indicated that low and/or decreasing levels of personal control were associated with the accumulation of fewer math/science credits, as were declining levels of parental consultation no matter what the initial level. Mismatches between control and consultation trajectories (e.g., high, stable control with low, stable consultation) were also associated with fewer math/science credits. These patterns tended to be less predictive of math/science credit accumulation at the highest and lowest ends of the socioeconomic spectrum.

Building on a conceptual model of the transition to elementary school, this study explored the role of health in the early cognitive achievement of children from various racial/ethnic minority and immigrant families by applying multilevel modeling to data from a nationally representative sample of American kindergarteners. Whites tended to have the best physical health before transitioning to first grade. Children from immigrant Latino/a and Asian families had the worst physical health but the best mental health. Compared to white children from native families, these health differentials partially explained the lower math achievement and achievement growth of black children (whether from native or immigrant families) in first grade as well as the lower math achievement of children from Latino/a immigrant families and the lower achievement growth of children from Asian immigrant families during this period.
