Religiosity is Associated with Motivation to Start and Stop Smoking Among Adolescent Students in Brazil.

This study aimed to estimate associations between adolescents' religiosity and their motivation to start and stop smoking. A school survey was carried out in Midwestern Brazil. Participants were never-smokers (n = 2073) and smokers (n = 116) aged 13-19 who answered a questionnaire. Religiosity was measured with the Duke Religion Index, and motivation with questions based on the Prime Theory of Motivation. Organizational, non-organizational, and intrinsic religiosity were associated with motivation to start smoking among never-smokers. Intrinsic religiosity was associated with smokers' motivation to quit. Findings indicate the protective role of religiosity in the motivational system that prompts smoking initiation and cessation during adolescence.
