To assess the effectiveness of intervention in improving knowledge, attitude and perception regarding smokeless tobacco (SLT) use and its harmful effects and intention to quit SLT among school going adolescents. A school-based cluster randomized control trial was carried out in 18 secondary schools targeting male and female students from grades 6 to 10 in Karachi. Primary outcome was knowledge about hazards of smokeless tobacco (SLT) and secondary outcomes were attitude and Perception about hazards of SLT, and intention to quit SLT. We enrolled 738 participants in intervention group and 589 in the control group. Mean score of knowledge significantly improved in intervention as compared to control group (P value < 0.01). Intention to quit was found to be proportionately higher (33%) in the intervention group as compared to control group. Generalized estimating equations were used to assess the association of factors with knowledge regarding harmful effects of SLT use. Significant predictors of increase in knowledge score were found in children: who had seen any anti SLT messages on social media in the past 30 days, who were getting information regarding harmful effects of SLT use in school or textbooks and who had friends using SLT. A school-based intervention was effective in increasing knowledge regarding the harmful effects of SLT use and intention to quit SLT use among school adolescents. Introduction of such educational programmes on a regular basis in schools or as part of school curriculum can have an impact on reducing prevalence of SLT use.Trial Registration NCT03418506. https://register.clinicaltrials.gov/NCT03418506 .
评估干预措施在提高青少年对无烟烟草（SLT）使用及其危害的认识、态度和观念，以及戒烟意图方面的有效性。在卡拉奇的 18 所中学中开展了一项基于学校的整群随机对照试验，目标是 6 至 10 年级的男女学生。主要结果是关于无烟烟草（SLT）危害的知识，次要结果是关于 SLT 危害的态度和观念，以及戒烟的意图。我们在干预组招募了 738 名参与者，在对照组招募了 589 名参与者。与对照组相比，干预组的知识得分显著提高（P 值<0.01）。发现干预组的戒烟意图比例较高（33%）。使用广义估计方程评估与 SLT 使用危害相关知识的因素关联。在儿童中发现了知识得分增加的显著预测因素：过去 30 天内在社交媒体上看到过任何反 SLT 信息的儿童、在学校或教科书中获得关于 SLT 使用危害信息的儿童、以及有使用 SLT 的朋友的儿童。基于学校的干预措施在提高青少年对 SLT 使用危害的认识和戒烟意图方面是有效的。在学校或作为学校课程的一部分定期引入此类教育计划，可以对减少 SLT 使用的流行率产生影响。试验注册 NCT03418506。https://register.clinicaltrials.gov/NCT03418506。
