Discrete time measures versus trajectories of drinking frequency across adolescence as predictors of binge drinking in young adulthood: a longitudinal investigation.

ABSTRACT:

Objectives

We compared discrete time measures with trajectories of adolescent drinking frequency as predictors of sustained binge drinking in young adulthood.

Design

Prospective longitudinal study.

Setting

10 high schools in Montréal, Canada.

Participants

1293 high-school students followed from mean (SD) age 12 (0.6) to 24 (0.7) years.

Primary outcome measures

Patterns of drinking frequency (self-reports every 3 months from ages 12 to 17) identified using group-based trajectory modelling. Sustained binge drinking was defined as binging monthly or more often at both ages 20 and 24.

Analyses

Using logistic regression, sustained binge drinking was regressed on trajectory group membership and on four discrete time measures (frequency of drinking at ag
