Mortality Risks Associated with Average Drinking Level and Episodic Heavy Drinking

Abstract

Data from the 1997 to 2004 National Health Interview Survey Sample Adult questionnaires were linked to the National Death Index (N = 242,397) to examine mortality risks associated with average and episodic heavy drinking. Cox proportional hazard models (Stata 12.0) revealed that (average) heavier drinkers and episodic heavy drinkers (5+ in a day) had increased mortality risks but when examined together, episodic heavy drinking added only modestly to the mortality risks of light and moderate drinkers. Limitations and implications of results for survey measurement of potentially harmful levels of alcohol use are noted. This was a Federal study that received no outside funding.
