Relationship among Sexual Orientation and Smoking, Drinking of Middle School Students

摘要: 目的：了解中学生性取向与吸烟、饮酒的关系，为其性教育及危险行为干预提供参考。方法：采用分层整群抽样，在重庆市某区四所中学选取3903名学生进行问卷调查。结果：24.8%中学生未确定性取向，65.9%为异性恋，2.8%为同性恋，6.5%为双性恋；不同性别、吸烟、饮酒的中学生性取向人数比差异有统计学意义(2 = 18.489、6.077、7.790，均P < 0.05)，男生异性恋(90.4%)高于女生(85.3%)，双性恋(6.3%)低于女生(10.5%)；吸烟、饮酒者双性恋(10.5%、10.3%)高于不吸烟、不饮酒者(7.7%、7.4%)，异性恋(86.0%、85.8%)低于不吸烟、不饮酒者(88.4%、88.9%)；同性恋比例差异均无统计学意义。中学生吸烟率为25.4%、饮酒率为34.3%；不同性别、性取向者吸烟、饮酒率差异有统计学意义(2 = 6.077、7.046，均P < 0.05)，男生吸烟、饮酒率(32.0%、42.6%)高于女生(43.0%、42.6%)；双性恋吸烟、饮酒率均(36.3%、53.0%)高于异性恋(29.0%、38.0%)、同性恋(27.3%、40.0%)。双性恋是中学生吸烟、饮酒的危险因素(OR = 1.403, 95%CI = 1.057~1.862; OR = 1.475, 95%CI = 1.129~1.927)。结论：应加强中学生性教育，引导其客观认知自身性取向，理性面对性少数群体；应重点加强双性恋者的危险行为干预，引导其合理减压，减低吸烟、饮酒行为的发生率。

Abstract: Objective: To investigate relationship among sexual orientation and smoking, drinking of middle school students, and provide suggestions for sex education and intervention of risk behavior. Methods: Using stratified cluster sampling and selected 3903 middle school students to complete questionnaires. Results: 24.8% middle school students’ sexual orientation was uncertain; 65.9% students were heterosexuality; 2.8% students were homosexual; 6.5% students were bisexual; there were significant differences between different gender, smoking, drinking students’ sexual orientation rate (2 = 18.489, 6.077, 7.790, both P < 0.05): the boys’ heterosexuality (90.4%) was beyond the girls’ (85.3%); bisexual (6.3%) was below the girls’ (10.5%); the smokers’ and drinkers’ bisexual (10.5%, 10.3%) was beyond the non-smokers’ and non-drinkers’ (7.7%, 7.4%); heterosexuality (86.0%, 85.8%) was below the non-smokers’ and non-drinkers’ (88.4%, 88.9%); the differences of homosexual were not significant. The smoking and drinking rate of middle school students were 25.4%, 34.3%; there were significant differences between different gender, sexual orientations’ smoking and drinking rate (2 = 6.077, 7.046, both P < 0.05); the boys’ (43.0%, 42.6%) was beyond the girls’ (32.0%, 42.6%); the bisexuals’ (36.3%, 53.0%) was beyond the hetero sexualities’ (29.0%, 38.0%) and homosexuals’ (27.3%, 40.0%). Bisexual was the risk factor of middle school students’ smoking and drinking (OR = 1.403, 95%CI = 1.057 - 1.862; OR = 1.475, 95%CI = 1.129 - 1.927). Conclusion: We should strengthen the sex education of middle school students, lead them to recognize self sexual orientation objectively and face sexual minorities rationally; strengthen risk behavior intervention for bisexual, lead them to reduce stress reasonably, and reduce their smoking and drinking rate.
