Effectiveness of a school-based multi-component smoking prevention intervention: The LdP cluster randomized controlled trial
Mené en Italie auprès de 989 lycéens âgés de 14 à 15 ans, cet essai randomisé évalue l'efficacité d'un programme d'interventions comportant des ateliers pédagogiques et une surveillance renforcée de l'application de la politique antitabac dans l'établissement pour réduire le nombre de fumeurs réguliers et le tabagisme au lycée
Objective : We assessed the effectiveness of the LdP school-based smoking prevention programme. Methods : We undertook a cluster randomized controlled trial of 989 students aged 14–15 years in 13 secondary schools located in Reggio Emilia, Italy. The intervention consisted of the "Smoking Prevention Tour" (SPT) out-of-school workshop, one in-depth lesson on one SPT topic, a life-skills peer-led intervention, and enforcement surveillance of school antismoking policy. Self-reported past 30-day smoking of > = 20 or 1–19 days of cigarette smoking (daily or frequent smoking, respectively) were recorded in 2 surveys administered immediately before and 18 months after the beginning of the programme. Analysis was by intention to treat. The effect of the intervention was evaluated using random effects logistic regression and propensity score-matching analyses." Results : Past 30-day smoking and daily cigarette use at eighteen months follow-up were 31% and 46% lower, respectively, for intervention students compared to control students. Taking into account non-smokers at baseline only, daily smoking at eighteen months follow-up was 59% lower in intervention students than in controls. Past 30-day smoking in school areas was 62% lower in intervention students compared to controls. Conclusions : the LdP programme was effective in reducing daily smokers and in reducing smoking in school areas.
