Objectives: We sought to study the association between adverse events occurring in childhood and adolescence and lifetime alcohol dependence in a representative sample of American adults.
Methods: With data from the National Epidemiologic Survey on Alcohol and Related Conditions, we conducted logistic regression multivariate analyses to examine the impact of adverse events occurring in childhood (aged < 18 years) on the lifetime prevalence of alcohol dependence. We controlled for age at drinking onset, binge drinking, alcoholism in parents and grandparents of respondents, and demographic characteristics.
Results: Adverse childhood events were associated with familial alcoholism and with early and binge drinking, and therefore, we controlled for these potential confounders. Experiencing 2 or more adverse childhood events, compared with none, significantly increased the risk for alcohol dependence, even after we controlled for sociodemographic variables and disorder-specific potential confounders not considered in the extant literature (adjusted odds ratio = 1.37; 95% confidence interval = 1.06, 1.77).
Conclusions: Individuals who experienced 2 or more adverse childhood events are at increased risk for lifetime alcohol dependence. A better understanding of the factors underlying the risk for alcohol dependence is important for developing better prevention and early intervention measures.
