Correlation between tobacco control policies and tobacco prevention in Mexico: a sub-national analysis.

This study aims to determinate the correlation between tobacco control policies (TCP) and the prevalence of tobacco use in the 32 Mexican states during the 2016-2017 period. This is an ecological study that measured TCP by the Tobacco Control Scale (TCS) which assigns a score (0-100) based on the level of these component's implementation: price, prohibition in public spaces, expenditures of public information campaigns, publicity prohibitions, health warnings, and treatments. We analyzed the associations between the TCS scores and prevalence of tobacco use extracted from the National Survey of Drug, Alcohol and Tobacco Consumption using Spearman correlations. Prevalence of daily smokers is negatively correlated with global TCS scores for adolescents (p = 0.026). Price showed similar negative correlations with daily prevalence in adolescents (p = 0.003), adults (p = 0.040), men (p < 0.006), and women (p = 0.040). Many Mexican states need to improve on tobacco control policies, especially targeting a key population: adolescents.
