The Influence of Pubertal Timing on Alcohol Use and Heavy Drinking Trajectories

Early pubertal timing has been associated with increased alcohol use, drunkenness, and alcohol use disorders in both boys and girls during adolescence. It is not clear, however, whether the effect of early pubertal timing persists into late adolescence and young adulthood, whether its effect differs by gender, and if contextual factors (e.g., peer alcohol use) amplify such effect. This study attempts to address these questions by examining the trajectories of alcohol use and heavy drinking from early adolescence to young adulthood in males and females using data from the National Longitudinal Study of Adolescent Health (Add Health). Results show that for both males and females, early pubertal timing was associated with higher alcohol use and heavy drinking trajectories. These effects persisted into young adulthood and were found to be stronger for males than for females. Moreover, there was a significant interaction effect between friends’ drinking and pubertal timing on alcohol use and heavy drinking trajectories; but the interaction effect also differed for males and females. These findings suggest that early pubertal timing is a risk factor for alcohol use and has long-term implication for individuals’ health. Michael Biehl’s research focuses on adolescent development and problem behaviors. He is particularly interested in developmental pathways leading to substance use and affective disorders and how different contexts influence these developmental pathways. Misaki Natsuaki is interested in how adolescent problem behavior changes over time. Her research focuses particularly on the effects and timing of transitional events, such as puberty, on trajectories of internalizing and externalizing behaviors in adolescence. Xiaojia Ge’s research focuses on interaction effects of biological and social contextual factors on socioemotional development. He is particularly interested in how pubertal timing affects adolescent development.

Gender Differences in the Association between Maternal Depressed Mood and Child Depressive Phenomena from Grade 3 through Grade 10

This study reports on relationships among gender, maternal depressed mood, and children’s trajectories of depressive phenomena across middle childhood and early adolescence. It tested the hypothesis that, compared to boys, girls become increasingly vulnerable to maternal depression as they enter adolescence. The study sample consisted of 834 families from 10 Pacific Northwest schools that participated in the Raising Healthy Children project. Maternal depressed mood and children’s depressive phenomena were assessed annually during an 8-year period that spanned Grade 3 through Grade 10 for the children. Mean scores for girls’ depressive phenomena increased relative to those for boys as children matured. Maternal depressed mood was significantly and positively associated with children’s level of depressive phenomena. An interaction effect of gender and maternal depressed mood on acceleration in children’s depressive phenomena indicated that girls’ trajectories of depressive phenomena were sustained in the presence of maternal depression while those of boys declined in the presence of maternal depression.
