Developmental trajectories of alcohol use among monoracial and biracial Black adolescents and adults.

OBJECTIVE

The present study investigates developmental trajectories of alcohol use from early adolescence to adulthood by age and race/ethnicity among White, Black, Black-American Indian, Black-Hispanic, and Black-White individuals and associated sociodemograhphic correlates.

METHOD

We used a subsample of nationally representative data obtained from the National Longitudinal Study of Adolescent Health (Add Health). The analytic sample consisted of 15,278 individuals in Wave 1 (ages 11 to 21 years). The sample consists of adolescents who were in Grades 7-12 at wave one and who were followed across four waves of data collection into adulthood. Respondents could report more than one race/ethnicity.

RESULTS

We find distinct alcohol trajectories among monoracial and biracial/ethnic Blacks with all groups showing a cross-over or catch-up effect. Black-White adults demonstrated a cross-over effect by surpassing the alcohol drinking rates of Whites in adulthood, Black-American Indians showed a within-group catch-up effect by surpassing the alcohol drinking rates of monoracial and biracial/ethnic Blacks in adulthood, and monoracial Blacks were most likely to be non-drinkers in adulthood. We also show gender, socioeconomic status, and household structure differences in impact on alcohol use among monoracial and biracial/ethnic Blacks.

CONCLUSIONS

Significant heterogeneity is observed regarding alcohol trajectories between monoracial and biracial/ethnic Blacks.
