(HealthDay)—For underage women, high-risk trajectories have been identified for heavy episodic drinking (HED), and feminine norms are associated with latent trajectory classes, according to a study published online Feb. 7 in Alcoholism: Clinical & Experimental Research.
Derek Kenji Iwamoto, Ph.D., from the University of Maryland-College Park, and colleagues used growth mixture modeling to identify latent trajectory classes of HED at three time points over the course of a year in 700 underage young adult women from a Mid-Atlantic university. Feminine norm endorsement, sorority status, perceived peer norms, expectancies, alcohol-related consequences, and marijuana use were examined as predictors of latent trajectory class.
