Abstract
Background: There are a wide number of assessments suggesting that being a member of a religious community inhibits adolescents’ risky behaviours and, consequently, can act as a protective factor against the consumption of smoking substances.
Methods: We have analysed a structured questionnaire answered by 1935 adolescents from Tarragona (Spain).
Results: We have found that variables linked to family were the principal explanatory factors of adolescents’ smoking habits. Living with two parents was a protective factor against tobacco and cannabis use since its Incidence Rate Ratio (IRR) was clearly below 1 (p1 (p<0.05), adolescents that live without parents presented an IRR close 2 (p<0.05 for tobacco and p<0.01 for cannabis). However, having a religious confession also influence smoking substance use in adolescents (IRR close to 0.85 with p<0.01).
Conclusion: We found a clear preventive effect in belonging to a religious community. Moreover, this protective effect was less intense, but not statistically significant, for Catholics than for members of other confessions.
