Objective. To evaluate the social factors associated with tobacco and alcohol consumption in Mexican adolescents from populations under 100 000 inhabitants. Materials and methods. Cross-sectional study based on the National Health and Nutrition Survey (Ensanut100k). It included adolescents between 10-19 years. Adjusted logistic regression models were estimated, obtaining Odds Ratio (OR) and confidence intervals 95% (CI95%). Results. Prevalence of tobacco consumption in the last month was 5.5% (10-14 years= 1.0%, 15-19 years= 11.2%); alcohol consumption 9.3%, and excessive alcohol consumption, 2.8%. Associated factors: smoking, sex (male, OR=6.00, CI95%: 2.89-12.46), age (OR=1.73, CI95%: 1.46-2.04), remunerated work (OR=2.87, CI95%: 1.12-7.34), affiliation to health services (OR=0.26, CI95%: 0.08-0.82); alcohol consumption, (male, OR=5.11, CI95%: 2.38-11.00), age (OR=1.70, CI95%: 1.51-1.92), remunerated work (OR=2.51, CI95%: 1.01-6.24). Conclusions. To reduce the consumption of alcohol and tobacco in adolescents, comprehensive prevention strategies must be implemented that consider the individual and social context.
