The current investigation determined that military personnel who drink heavily differ from those who drink moderately in the practice of nine behaviors often associated with unhealthy lifestyle. In particular, excessive drinkers were found to smoke more, drive dangerously more frequently, and consume saturated fats more often. The project further found that the relationship of excessive drinking to these activities is mediated by age, marital status, and race, although not by gender or rank. Implications of the findings for prevention and treatment are suggested.
