BEZERRA, J. et al. Alcohol consumption and smoking: relationship to leisure-time physical inactivity and sedentary behavior. Rev Andal Med Deporte [online]. 2015, vol.8, n.1, pp.1-6. ISSN 2172-5063.  https://dx.doi.org/10.1016/j.ramd.2014.08.002.

Objective: To analyze the relationship between exposure to alcohol consumption and smoking to leisure-time physical inactivity (LTPI) and sedentary behavior (SB) in adolescents. Method: This cross-sectional study included a representative sample of high school students from public schools in Pernambuco State (Brazil) (n = 4207, 14-19 years). The data were collected using a previously validated questionnaire. The time spent watching television was used as a measure of sedentary behavior on weekdays (WKDSB) and weekend (WKESB) (> 2 hours/day = exposed to sedentary behavior). The lack of physical activity in free time was considered as leisure-time physical inactivity (LTPI). Binary logistic regression was used to analyze the association between variables, considering the results of LTPI and SB. Results: The prevalence found were INL = 38.2% (Confidence interval (CI) 95%: 36.7 - 39.7), CSS = 40.8% (CI 95%: 39.3 - 42.3) and CFS = 49.9% (CI 95%: 48.4 - 51.4). After adjustment (demographic, socioeconomic and school factors), exposure to smoking and alcohol consumption were inversely associated with LTPI. The adolescents who consumed alcohol had 27% less chance of LTPI compared to those who did not consumed alcohol. Similarly, smoker students had 28% less chance of LTPI than those who did not smoke. Regarding SB, it was found that smoker students had 28% less chance of exposure to WKESB. Conclusion: It was concluded that consumption of alcoholic beverages and smoking are inversely associated with the LTPI and WKESB, confirming findings already reported in the literature in adult studies.
