title: Trajectories of alcohol use among adolescent boys and girls: identification, validation, and sociodemographic characteristics.
abstract: This longitudinal study used data from a secondary data archive of 1,619 East German adolescents (mean age, 14.05 years at the initial wave). Latent growth mixture modeling was used to identify distinctive developmental trajectories of alcohol consumption from ages 14 through 18 years. Four groups were found for both boys (rare users, late escalators, early peakers, regular users) and girls (rare users, increasers, decreasers, regular users). Further analyses showed reasonably good external validity of the identified alcohol consumption trajectories. Finally, female alcohol use trajectory groups differed in terms of financial resources (socioeconomic backgrounds), whereas male trajectory groups did not differ at all in terms of sociodemographic characteristics. Overall, evidence for gender-specific alcohol use trajectories was mixed.
