Objective: To examine the relationship between alcohol and tobacco use and sports in a national sample of secondary students. Methods: This cross-sectional study enrolled a representative sample of secondary students from public and private schools from all 27 Brazilian state capitals. Students were assessed in 2010 by a self-report questionnaire including questions on drug use and sport activity in the last month (n=13,872). Results: Subjects who played sports exhibited a higher frequency of alcohol use and heavy episodic drinking than their peers who did not play sports. Practices that were associated with higher odds of heavy episodic drinking in the last month included gym, weight training (adjusted odds ratio [aOR]: 2.0, 95% confidence interval [95%CI] 1.6-2.4), and soccer (aOR: 1.3, 95%CI 1.1-1.5). Fighting, martial arts, or capoeira were associated with smoking (aOR: 1.9, 95%CI 1.2-3.2). Conclusion: These results suggest a relationship between some sports preferences and a higher risk of alcohol or tobacco use among Brazilian secondary students. This relationship should be considered in preventive programs.Keywords: Sports; exercise; alcohol drinking; tobacco; adolescent
IntroductionAdolescence is a critical period in the development of substance use and abuse patterns.1 Alcohol and tobacco are the psychotropic substances most commonly used by Brazilian students between the ages of 14 and 18 years old.
2Since the early 1980s, several studies have explored the association between participation in sports and drug use.3 Studies point to physical exercise as a possible therapeutic intervention against the abuse of various types of drugs. 4,5 Moreover, the literature presents inconsistent evidence about sports participation as a risk or a protective factor for drug use, 6 particularly among adolescent students.In several studies, sports participation among high school students was associated with higher alcohol consumption, 7,8 heavy episodic drinking (HED), 9 and tobacco use. 10 Conversely, other studies have observed that participation in sports is associated with decreased use of these substances. 11,12 However, all these studies focused on North American and European populations.Several characteristics of sports practice seem to influence its relationship with substance use, including the type of sport 4,13 and the frequency of and motivation for participating in sports. 3,8,14 Some authors point out the importance of social and cultural aspects [14][15][16] in understanding the relationship between sports and drugs. Adolescents are subject to considerable peer influence regarding alcohol and tobacco use. 17,18 Among sports players, alcohol consumption can be encouraged as a way to strengthen group bonds. 19 In contrast, the exact nature of the sport can attract different types of students. For example, men who are interested in more aggressive sports may be more susceptible to high-risk behaviors.
