Moderate alcohol use and depression in young adults: findings from a national longitudinal study

OBJECTIVES: We examined the association between moderate alcohol use and depressive mood among young adults before and after adjustment for demographic, health, and socioeconomic factors that may act as confounders. METHODS: We analyzed 2 waves of interview data collected from 13892 young adults who participated in the National Longitudinal Study of Adolescent Health to compare frequency of depressive symptoms in moderate drinkers with frequency of symptoms in young adults in other alcohol use categories. RESULTS: With adjustment for health and socioeconomic factors, frequency of depressive symptoms were similar among moderate drinkers, lifetime and long-term abstainers, and heavy/heavier moderate drinkers but remained significantly higher among heavy drinkers. CONCLUSIONS: Moderate alcohol use may have no effect on depression in young adults relative to abstinence from alcohol use.
