Abstract

To obtain nationally representative estimates of the prevalence of secondhand smoke (SHS) exposure at U.S. schools, we assessed the prevalence and correlates of SHS exposure at school among U.S. middle and high school students using data from the 2011 National Youth Tobacco Survey comprising of 18,866 students spread across all the U.S. states. Overall prevalence of SHS exposure at school was 25.7% (95% CI: [23.6%, 27.8%]). Multivariate logistic regression indicated that having ≥1 smoker friends (adjusted Odds Ratio [aOR] = 2.92; p < .001); being a smoker (aOR = 2.75; p < .001); and being aged 13-16 years, or ≥17 years (vs. 9-12 years) significantly increased the likelihood of SHS exposure. Understanding the health risks of SHS exposure alone did not seem to play a significant role in reducing exposure (aOR = .89; p = .342). These findings show there are significant levels of SHS exposure among students at U.S. middle and high schools, and sustained multipronged efforts are needed to reduce youth SHS exposure.

摘要

为了获得美国学校二手烟暴露率具有全国代表性的估计值，我们利用2011年全国青少年烟草调查的数据，评估了美国初中和高中学生在学校二手烟暴露的发生率及其相关因素，该调查涵盖了美国所有州的18,866名学生。学校二手烟暴露的总体发生率为25.7%（95%置信区间：[23.6%，27.8%]）。多因素逻辑回归表明，有≥1个吸烟的朋友（调整后的优势比[aOR]=2.92；p<.001）；自己是吸烟者（aOR=2.75；p<.001）；以及年龄在13 - 16岁或≥17岁（与9 - 12岁相比）显著增加了二手烟暴露的可能性。仅了解二手烟暴露的健康风险似乎在减少暴露方面没有起到显著作用（aOR=.89；p=.342）。这些研究结果表明，美国初中和高中学生中二手烟暴露水平较高，需要持续采取多方面的努力来减少青少年二手烟暴露。
