The relationship between sporting activity and smoking habits in young adults.

The authors investigated the relationship between sporting activity and smoking habits in young Italian men. One thousand, one hundred fifty-three men, age 20 years, completed a self-administered questionnaire on their smoking habits and sporting activity patterns. Five hundred sixty subjects (53%) were found to be smokers, with a high prevalence of heavy smokers (33.6%). Four hundred sixty-four (44%) of the examined subjects were sportsmen. In the group of young men not engaged in sports, the rate of smokers was significantly higher. Non-sportsmen started smoking earlier than sportsmen, and the prevalence of heavy smokers was significantly higher in the non-sportsmen group than in the sportsmen group. Finally, the young men not engaged in sports were more likely to be habitual smoke inhalers than sportsmen. These results suggest that sporting activity may indirectly influence smoking habits.
