Understanding the social determinants that influence adolescent smoking behavior has a meaningful impact on adolescent health. Few studies have simultaneously analyzed the impact of teacher smoking and peer smoking on adolescent smoking. Therefore, the present study aims to investigate the impact of teacher smoking, peer smoking, and other social factors, on adolescent smoking.
The participants were drawn from schools in Beijing, China, in 2011, 2013, and 2015, using a multi-stage random group sampling method. The number of schools selected for each year was 160. The study participants were 57240 adolescents aged 8-19 years. The generalized linear model with a binomial distribution and logarithmic link function was used to estimate the influence of social determinants on adolescent smoking behavior.
The results show that both teacher smoking and peer smoking were significantly associated with adolescent smoking. Compared to adolescents whose teachers did not smoke, the prevalence ratio (PR) was 1.28 for adolescents with one teacher who smoked and 1.34 for adolescents with two or more teachers who smoked (95% CI: 1.16-1.41/1.23-1.46, p<0.001/0.001, respectively). Compared to adolescents whose peers did not smoke, the prevalence ratio (PR) was 3.73 for adolescents with one peer who smoked and 8.52 for adolescents with two or more peers who smoked (95% CI: 3.20-4.35/7.48-9.69, p<0.001/0.001, respectively).
Teacher smoking and peer smoking are significant social determinants of adolescent smoking. Prevention programs should concurrently target peer groups, school settings, and individual students.
了解影响青少年吸烟行为的社会决定因素对青少年健康具有重要意义。很少有研究同时分析教师吸烟和同伴吸烟对青少年吸烟的影响。因此，本研究旨在探讨教师吸烟、同伴吸烟及其他社会因素对青少年吸烟的影响。
研究对象于2011年、2013年和2015年从中国北京的学校中选取，采用多阶段随机分组抽样方法。每年选取的学校数量为160所。研究参与者为57240名8 - 19岁的青少年。采用二项分布和对数链接函数的广义线性模型来估计社会决定因素对青少年吸烟行为的影响。
结果表明，教师吸烟和同伴吸烟均与青少年吸烟显著相关。与教师不吸烟的青少年相比，有一位吸烟教师的青少年的患病率比值（PR）为1.28，有两位或更多吸烟教师的青少年的患病率比值为1.34（95%置信区间：1.16 - 1.41/1.23 - 1.46，p分别<0.001/0.001）。与同伴不吸烟的青少年相比，有一位吸烟同伴的青少年的患病率比值（PR）为3.73，有两位或更多吸烟同伴的青少年的患病率比值为8.52（95%置信区间：3.20 - 4.35/7.48 - 9.69，p分别<0.001/0.001）。
教师吸烟和同伴吸烟是青少年吸烟的重要社会决定因素。预防项目应同时针对同伴群体、学校环境和个体学生。
