Abstract: | 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. |
