本研究的目的是评估的有效性自我报告的吸烟流行率在韩国青少年使用改进的金标准的组合方法。使用分层抽样方法，我们从参加2015年韩国青少年健康风险行为网络调查（KYRBS）的397所高中中选择了13所学校。第二项调查（重复自我报告问卷和尿可替宁试验）进行了1058名学生谁完成了KYRBS。当前吸烟者的金标准定义为在第二次调查中自我报告为吸烟者或尿可替宁浓度≥50 ng/mL的患者。第一次调查（KYRBS）中目前的吸烟率为7.9%（男孩16.5%，女孩1.8%），低于基于黄金标准的结果（总计11.3%，男孩21.9%，女孩3.7%）。自我报告吸烟状况的敏感性和特异性分别为62.5%和99.0%。特别是，女孩的敏感性（43.5%）低于男孩（67.0%）。韩国青少年自我报告的吸烟率被低估了，尤其是女孩。应仔细注意解释青少年吸烟率，亚洲国家需要考虑进行补充调查或定期有效性测试。
The objective of this study was to evaluate the validity of self-reported smoking prevalence in Korean adolescents by using an improved gold standard by a combined method. Using a stratified sampling method, we selected 13 schools from among 397 high schools that participated in the 2015 Korean Youth Health Risk Behavior Web-Based Survey (KYRBS). A second survey (repeated self-reporting questionnaire and urinary cotinine test) was conducted on 1058 students who completed the KYRBS. The gold standard of current smoker was defined as those either self-reporting as a smoker in the second survey or having a urinary cotinine concentration ≥50 ng/mL. The current smoking prevalence in the first survey (KYRBS) was 7.9% (boys 16.5% and girls 1.8%), which was lower than the results based on gold standard (11.3% total, boys 21.9% and girls 3.7%). The sensitivity and specificity of self-reported smoking status was 62.5% and 99.0%, respectively. In particular, the sensitivity of girls (43.5%) was lower than that of boys (67.0%). The self-reported smoking prevalence in Korean adolescents was underestimated, particularly among girls. Careful attention should be paid to interpreting adolescents’ smoking prevalence, and supplementary surveys or periodic validity tests need to be considered in Asian countries.
