Abstract

Abstract: Aims: To evaluate the influences of alcohol consumption frequency and binge drinking on changes in the body composition, lifestyle habits and physical fitness of healthy young men during military service. Methods: A population-based study of men performing their military service in the Sodankylä Jaeger Brigade, Finland in 2005. Body composition, fitness and lifestyle habits were evaluated at baseline and 6–12 months follow-up. Alcohol consumption frequency and binge drinking were categorized as: 'not at all', 'at least once a month' and 'at least once a week'. Results: Data were available for 983 participants. Mean (SD) age was 19.2 (1.0) years. At baseline, participants who reported binge drinking at least once a week (29.8%) had the most unfavourable body composition, lifestyle habits and physical fitness compared with the group with no binge drinking. Significant ( P < 0.05) mean reductions in % body fat (−2.3%) and weight (−1.8 kg), as well as improvements in lifestyle habits and physical fitness were observed in the weekly binge drinking group during the military service. The reductions in relative weight (%) and % body fat were associated with binge drinking at least once a week (regression coefficient for relative weight −1.39, 95% CI [−2.32; −0.45], P = 0.004, and for % body fat −0.68, 95% CI [−1.35; −0.01], P = 0.049). Conclusion: Frequent binge drinking is associated with poorer body composition, lifestyle habits and fitness among young men. Frequent binge drinkers may obtain the greatest benefit of military-service-based exercise intervention, as reflected in the improvements in body composition, lifestyle habits and physical fitness. Short summary: Frequent binge drinking is associated with poorer body composition, lifestyle habits and fitness among young men. The greatest benefit of military service comprehending exercise intervention was observed among those with binge drinking once a week at the baseline, with favourable changes in lifestyle factors, body composition and fitness.
