评估世界各地烟草控制的进展在很大程度上依赖于吸烟流行率的估计。这些估计通常是基于对自我报告的吸烟状况的调查。本研究的目的是评估中国青少年吸烟的流行率和自我报告吸烟状况的准确性，这项基于人群的横断面调查包括来自中国上海市17所学校的10，934名12至18岁的青少年。青少年吸烟状况的数据分别来自青少年的自我报告和父母的问卷。根据两个来源的数据，使用捕获-再捕获方法估计了研究参与者中的吸烟者总数。在5，452名女孩和5，482名男孩中，男孩和女孩的自我报告吸烟率估计分别为13.6%（748）和5.2%（284）。父母只发现了较小比例的吸烟青少年：2. 9%（160）的男孩和0. 6%（30）的女孩。使用捕获-再捕获法，我们估计男孩和女孩的吸烟率分别为18.3%（95%CI 16.4，20.3）和14.2%（95%CI 7.6，20.8）。自我报告的吸烟者仅占女孩实际吸烟者的一半以下。我们的研究结果对于监测中国青少年的吸烟趋势和评估烟草控制干预措施具有重要意义。
Evaluating the progress of tobacco control across the world heavily relies on smoking prevalence estimates. Those estimates are often based on surveys of self-reported cigarette smoking status. The accuracy varies among populations with different social and cultural backgrounds.The objective of this study was to estimate the prevalence of smoking and assess the accuracy of self-report smoking status in Chinese adolescents.This population-based cross-sectional survey included 10,934 adolescents aged 12 to 18 years from 17 schools in Shanghai, China. Data on adolescents' smoking status were collected from adolescents' self-reporting and from parents' questionnaires, separately. Based on the data of two sources, the total number of smokers among the study participants was estimated using a capture-recapture method.Among 5,452 girls and 5,482 boys, the prevalence estimates of self-reported smoking were 13.6 % (748) and 5.2 % (284) for boys and girls, respectively. Parents only identified smaller proportions of smoking adolescents: 2.9 % (160) boys and 0.6 % (30) girls. Using the capture-recapture method, we estimated the prevalence of smoking as 18.3 % (95 % CI 16.4, 20.3) for boys and 14.2 % (95 % CI 7.6, 20.8) for girls.Reliance on self-reporting to identify smokers among Chinese adolescents significantly underestimates the number of smokers, particularly among Chinese girls. Self-reported smokers only represent less than half of actual smokers in girls. Our findings are important for monitoring smoking trends and evaluating tobacco control interventions among Chinese adolescents.
