Objective: Understanding moderators of the relationship between physical activity (PA) and alcohol use is important for clarifying the mechanisms underlying these behaviors and informing health promotion interventions. This study examined age and gender as two candidate moderators of the PA-alcohol use link. Method: As part of a correlational, cross-sectional population-based study of US 34,653 adults, participants were administered surveys assessing demographics, alcohol use, moderate and vigorous PA, and other characteristics. Composite indices of the frequency and quantity of alcohol use and PA were utilized in analyses. Results: Age moderated the association between past-year vigorous PA and alcohol use (ps ≥ 01). Vigorous PA was positively associated with alcohol use in individuals under 50. years of age (ps ≥ 05), but not in individuals over 50. years of age (ps ≥ 0.05). Gender moderated the association between past-year moderate PA and alcohol use (ps < 001). The relation was stronger in males (β=.72) than in females (β=.41). Each of the findings remained significant even when controlling for demographics, psychiatric variables, and other potential confounds. Conclusion: Among the American population of adults, age appears to moderate the relationship between vigorous PA and alcohol use, whereas gender appears to moderate the relationship between moderate PA and alcohol use. These findings shed light on the underlying mechanisms that may account for increased alcohol use in exercisers and may have clinical implications for alcohol screening and interventions in adults who lead active lifestyles. © 2011 Elsevier Ltd.

Previous research has examined protective behavioral strategies (PBS), or cognitive-behavioral strategies that may be employed when using alcohol to reduce consumption and related problems, as an important predictor of alcohol use and alcohol-related problems. More recently, studies have explored the mediating and moderating role of PBS on the relationships between key alcohol-related risk factors (i.e., drinking motives, depressive symptoms, binge drinking) and alcohol problems; however, current research examining PBS as a moderator of the relationship between alcohol use and related problems has methodological limitations. The purpose of the present study was to extend previous literature to examine the moderating effect of PBS on the relationship between binge drinking and alcohol-related problems. Data were collected and analyzed from 4,154 students at 13 midwestern universities. Findings indicated that PBS moderated the binge drinking-alcohol problems relationship for each of the four measures of binge drinking. However, effects were strongest when binge drinking was measured dichotomously versus continuously. Implications and future directions are discussed. © 2011 American Psychological Association.
