Joint effect of school and family on domestic second-hand smoke exposure in middle school students

Abstract

Objective To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents.

Methods A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected.

Results The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’ s home ( OR = 22.88, P<0.05). Among the students who saw the "clear no-smoking label” on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) ( χ ² =452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus ( OR = 0.08) and had the school’ s tobacco control education ( OR = 0.08).

Conclusion The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.

【摘要】目的 观察学校与家庭控烟对中学生的联合作用, 探讨其对降低中学生家庭二手烟暴露的有效性, 以期为 中学生控烟工作提供新思路。 方法 采用分层整群随机抽样的方法, 在北京市东城区抽取 4 所中学的所有初一和髙一学 生共 2 125 名开展问卷调査。调査内容包括中学生个人基本信息, 中学生家庭、学校和周围社会控烟环境情况及中学生控 烟相关知识、态度和行为等。 结果 北京市东城区中学生的家庭二手烟暴露率为 33.41 %。在校园内见过“明确禁烟标识” 的学生中, 家里有限制吸烟规定的暴露率 (4.92%) 低于家里没有规定的学生 (58.94%) ( χ ²=452.57, P<0.01) 。 Logistic 回归 分析结果显示, 父母至少一方吸烟与学生家庭二手烟暴露呈正相关 ( OR = 22.88, P<0.05);有家庭限制吸烟规定分别与见过 校园内禁烟标识 ( OR = 0.08)、在学校接受过控烟宣教 ( OR = 0.08) 对中学生的家庭二手烟暴露存在联合作用。 结论 学校 与家庭的联合控烟措施能有效降低中学生家庭二手烟暴露率, 较二者单独控烟作用更优。
