Abstract
AIMS
There is little known about the extent to which maternal alcohol consumption influences offspring's alcohol use disorder. This study aims to examine whether different maternal alcohol consumption trajectories predict gender difference in adolescent alcohol use disorder at child age 21 years.
METHODS
Data are from a prospective cohort, the Mater-University of Queensland Study of Pregnancy (MUSP) and its outcomes. The study involves 2531 mother-child pairs for whom data are available at the 21-year follow-up survey. Maternal alcohol consumption trajectories were determined by group-based trajectory modelling. Offspring's lifetime ever alcohol use disorder was assessed using DSM-IV diagnostic criteria.
RESULTS
Over 14 years of follow-up after the birth of a child, three distinct alcohol consumption trajectories were identified (abstainer, low-stable. and moderate-escalating drinker). A maternal trajectory of moderate-escalating alcohol consumption independently predicted offspring's lifetime ever alcohol use disorder at 21 years after adjustment for a range of potential confounders. "Cross-gender influence" is observed in the study.
CONCLUSIONS
A maternal life course pattern of alcohol consumption may have an independent effect on offspring alcohol consumption, with male offspring being more vulnerable to the effects of maternal alcohol use than are female offspring. Programs intended to address alcohol consumption by adolescents and young adults need to focus on the behaviors of both parents but acknowledging that maternal patterns of alcohol consumption may be particularly important for male offspring.
