Self-reported mental health outcomes in prenatally cocaine exposed adolescents at 17 years of age

Abstract

ObjectiveAdverse developmental effects of prenatal cocaine exposure (PCE) are hypothesized to extend into late adolescence, yet few studies have investigated the association between PCE and late adolescent mental health outcomes. We examined the associations between PCE and self-reported mental health symptoms at age 17, controlling for biologic and environmental confounders. We further explored the potential moderating role of sex and the mediating role of earlier drug use by age 15 in the associations. Method327 (162 PCE; 165 non-cocaine exposed, NCE) urban adolescents, primarily African Americans, of low socioeconomic status, were prospectively recruited at birth for a longitudinal study and participated in the current study. We administered the Computerized Diagnostic Interview Schedule for Children-IV to assess their mental health symptoms at age 17. Alcohol, tobacco, and marijuana use by age 15 were assessed using biologic samples and self-reports. Confounders included other prenatal drug exposures, caregiving environment, and childhood maltreatment. ResultsAlthough no overall associations between PCE and mental health outcomes were observed, multivariate logistic regression models indicate girls with PCE were 3.60 times (95% CI = 1.45–8.96, p = .006) more likely to have symptoms of oppositional defiance disorder than girls with NCE. This relationship was partially mediated by marijuana use by age 15. ConclusionContinued studies into emerging adulthood will further elucidate the long-term mental health outcomes associated with PCE.
