Maternal Age and Trajectories of Risky Alcohol Use: A Prospective Study.

ABSTRACT:

Background

No prospective study of maternal alcohol use has focused on age at transition to motherhood as a predictor of trajectories of risky drinking. The goal of this study was to examine the impact of maternal age at first birth on trajectories of alcohol use beyond recommended levels over a 17-year span.

Methods

Pregnant women (N = 456) were recruited at an urban prenatal clinic. The women (13 to 42 years old; 64% African American, 36% White) were interviewed about alcohol use during pregnancy and at 6, 10, 14, and 16 years postpartum. Growth mixture modeling (GMM) was used to identify trajectories of risky drinking. Maternal age at first birth was then regressed onto trajectory class membership.

Results

The GMM on maternal alcohol use identified 3 groups of moth
