A cross-sectional survey of the smoking habits of 330 17-19 year-old males practising physical activity as members of sports teams, and of 366 male students in the same age range was carried out in Brescia, North Italy. A total of 23.3% of the athletes and 30.9% of the students smoked at least one cigarette a week (chi 2 = 4.60, p less than 0.05), and 17.3% and 19.7% smoked at least one cigarette a day, respectively (chi 2 = 0.51; p greater than 0.05). The smoking athletes had on average 50.3 cigarettes/week and students 47.0 (t-test: 0.46; p greater than 0.05). No difference was found with respect to age at their first experience with smoking, while athletes began to smoke regularly before than students, proportionally (chi 2 for linear trend: 5.29, p less than 0.05). Sporting activity was negatively associated with current smoking by multiple logistic regression: the odds ratio of current smoking for athletes with respect to students was 0.5 (95% CI: 0.4-0.8). Among a set of social, environmental and behavioural variables, best friend's and girlfriend's smoking was the one most strongly associated with current smoking in both groups.
