Episodic Heavy Drinking and 20-Year TotalMortality Among Late- Life Moderate Drinkers

BackgroundAnalyses of moderate drinking have focused overwhelmingly on average consumption, which masks diverse underlying drinking patterns. This study examined the association between episodic heavy drinking and total mortality among moderate-drinking older adults. MethodsAt baseline, the sample was comprised of 446 adults aged 55 to 65; 74 moderate drinkers who engaged in episodic heavy drinking and 372 regular moderate drinkers. The database at baseline also included a broad set of sociodemographic, behavioral, and health status covariates. Death across a 20-year follow-up period was confirmed primarily by death certificate. ResultsIn multiple logistic regression analyses, after adjusting for all covariates, as well as overall alcohol consumption, moderate drinkers who engaged in episodic heavy drinking had more than 2 times higher odds of 20-year mortality in comparison with regular moderate drinkers. ConclusionsAmong older moderate drinkers, those who engage in episodic heavy drinking show significantly increased total mortality risk compared to regular moderate drinkers. Episodic heavy drinkingeven when average consumption remains moderateis a significant public health concern.
