Abstract:

PURPOSE: To assess whether the higher prevalence of childhood trauma exposure but lower prevalence of alcohol use in Black vs. White adolescent girls reflects a lower magnitude of association between trauma and alcohol use initiation in Black girls; and additionally, whether low socioeconomic status (SES) and neighborhood factors account in part for the link between trauma and early alcohol use. METHODS: Data were drawn from annual interviews conducted with an urban sample of girls and their primary caregivers from ages 5-8 (baseline) through age 17 (n? = 2068, 57.7% Black, 42.3% White). Cox proportional hazards regression analyses using race and childhood trauma to predict alcohol use initiation were conducted in two stages, with SES and neighborhood factors added in the second stage. RESULTS: Childhood trauma was more prevalent (29.0 vs. 17.5%) and alcohol use initiation less prevalent (37.7 vs. 54.4%) in Black vs. White girls, but we found no evidence for differences in liability conferred by trauma. However, significant changes in hazards ratios (HRs) from the unadjusted to adjusted models were observed for Black race (HR? = 0.57, CI 0.50-0.65 to HR? = 0.66, CI 0.54-0.80) and childhood trauma (HR? = 1.70, CI 1.46-1.99 to HR? = 1.34, CI 1.05-1.71). CONCLUSIONS: Findings indicate that childhood trauma is an equally potent risk factor for early drinking onset for Black and White girls; the risk for early alcohol use in Black girls who have experienced traumatic events should not be underestimated. Results further indicate that low SES and neighborhood factors contribute to the associations of childhood trauma and race with alcohol use initiation.
