Méta-Analyse des Challenges Inter-Lycées (CIL) de 2017 à 2019 : évaluation de l’impact global sur la réduction et l’arrêt du tabac à un mois des défis collectifs dans quarante lycées de Nouvelle-Aquitaine et du Grand Est

Abstract : Background: the Inter-High Schools Challenge (IHSC) is a one-month prevention and risk reduction school program against smoking, set up in high schools in the Nouvelle-Aquitaine and the Grand Est regions during the “Month without Tobacco” from 2017 to 2019. The objective of these competitions between classes and between high schools in the same region was to quit smoking for "challengers" with the help of non-smokers of their class. In the end, the class with the most points was rewarded of a group trip to an amusement park. Objectives: the main objective of our study was to meta-analyse the results of IHSC-related studies to know the overall effect in terms of positive changes (reduction and cessation) of the behaviour of smokers who participated in the Inter-Classes Challenges organised in November, from 2017 to 2019. The secondary objectives were to assess the evolution of students' knowledge during the IHSCs as well as their appreciation of this academic challenge. Method: a systematic review of studies on prevention and cessation assistance programs in schools using different databases such as MEDLINE and PUBMED was carried out and allowed us to select five quantitative studies that followed and analysed the IHSC protocol. The data compiled came from responses to self-report questionnaires completed by high school students participating in the IHSCs. We were able to perform a meta-analysis on the data centralised using an aggregate statistical method. Results: in total, 6011 students were recruited, and 1652 smokers were mobilised. The results of the meta-analysis showed that there was no homogeneity between the 5 studies (p = 0.02) so to counter this heterogeneity, it was legitimate to choose the statistical random effects model of DerSimonian and Laird. The results of our review revealed a significant reduction in the number of cigarettes smoked per day by smokers in each of the studies after the challenge. An overall impact, also statistically significant, was demonstrated with an average decrease of 2.45 (95% CI [1.72-3.19]) cigarettes smoked per day at the end of the IHSC. A positive impact on quitting smoking has also been reported with at least 15% of committed smokers declaring that they have weaned. In terms of knowledge, the smokers and non-smokers keep a very good average of scores on the quizzes between D0 and D30, which shows a noteworthy learning in tobaccology. In addition, the IHSCs were generally very appreciated by all the high school students. Conclusion: these collective challenges had a statistically significant impact on the reduction in the tobacco consumption of participating smokers with a reduction of more than two cigarettes smoked per day on average at the end of this school program carried out three consecutive years in the Nouvelle-Aquitaine and in the Grand Est regions.
