Boys use cannabis at a younger age and more frequently than girls. It has been suggested these sex differences might vary according to students' relationship to school. We explored whether the association between sex and adolescents' cannabis use varies among schools and according to students' school connectedness.
The study population consisted of all students from 11 secondary schools in the greater Québec City area. The sample included 6185 respondents in years 1 to 5 at the secondary level (equivalent to grades 7-11). Study outcomes were monthly cannabis use and early cannabis use.
The association between sex and monthly cannabis use varied significantly among schools after controlling for students' main characteristics and school socioeconomic environment. We found a statistically significant modifying effect of school connectedness on the association between sex and monthly cannabis use. For early cannabis use, we found no modifying effect of school connectedness nor any association with sex.
Measures to reduce adolescents' cannabis use could be better adapted to local context and more tailored to specific higher-risk groups. School connectedness is a protective factor for cannabis use, although this effect appears stronger for girls than boys.
男孩比女孩更早且更频繁地使用大麻。有人认为，这种性别差异可能因学生与学校的关系而异。我们探讨了青少年大麻使用与性别的关联是否因学校而异，并根据学生的学校联系程度而有所不同。
研究人群包括大魁北克地区 11 所中学的所有学生。样本包括来自中学 1 至 5 年级（相当于 7-11 年级）的 6185 名应答者。研究结果为每月大麻使用和早期大麻使用。
在控制学生的主要特征和学校社会经济环境后，性别与每月大麻使用之间的关联在各学校之间存在显著差异。我们发现学校联系程度对性别与每月大麻使用之间的关联具有统计学上显著的调节作用。对于早期大麻使用，我们没有发现学校联系程度的调节作用，也没有发现与性别的关联。
减少青少年大麻使用的措施可以更好地适应当地情况，并更针对特定的高风险群体进行调整。学校联系是大麻使用的保护因素，尽管这种影响对女孩比对男孩更强。
