Abstract
PURPOSE: Earlier ages at menarche are associated with elevations in internalizing and externalizing that persist into adulthood. The present study examines whether early pubertal timing precipitates experiences during adolescence that account for long-term elevations in depressive symptoms and antisocial behavior among early maturing girls. METHODS: Using data from the National Longitudinal Study of Adolescent and Adult Health (Add Health), the study examines significant postmenarcheal life events that might mediate associations of age at menarche with depressive symptoms and antisocial behavior in adulthood: teenage criminal arrest, teenage pregnancy and childbearing, high school dropout, and different forms of postpubertal physical and sexual traumatic assault. RESULTS: Results indicate that earlier menarche was associated with greater likelihood of postmenarcheal discontinued education, physical and sexual assault, and teenage pregnancy and childbearing. Discontinued education, physical assault, and sexual assault mediated associations of pubertal timing with adult depressive symptoms; sexual assault mediated associations of pubertal timing with adult antisocial behavior. CONCLUSIONS: Earlier menarche seems to precipitate postpubertal stressful events that, in turn, account for higher rates of psychological problems in adulthood. These results suggest that the adolescent experiences of early maturing girls channel them into life paths where stress, adversity, and other risks to psychological well-being are more likely to be a continuing facet of daily life.
