目的：我们研究了无烟法律覆盖范围与有和无家庭二手烟（SHS）暴露的非吸烟青少年（3 - 19岁）可替宁之间的关联。
方法：我们使用了1999 - 2006年美国国家健康和营养检查调查的数据，这是一项旨在监测美国人口健康和营养状况的横断面调查。来自117个调查地点的11486名非吸烟青少年有血清可替宁水平数据。每个地点被分为3组中的1组，分别表示无烟法律的广泛覆盖、有限覆盖和无覆盖。可替宁被作为二分类（≥0.05纳克/毫升）和连续结果进行分析。
结果：在无家庭二手烟暴露的青少年中，生活在无烟空气法广泛覆盖县的那些人，可检测到可替宁的患病率经调整后是无烟空气法未覆盖地区青少年的0.61倍（95%置信区间：0.48 - 0.78），几何均值低0.57倍（95%置信区间：0.41 - 0.79）。在有家庭二手烟暴露的青少年中，无烟空气法广泛覆盖地区的青少年与生活在无烟空气法未覆盖县的青少年相比，几何均值可替宁较低，但在对协变量进行调整后，这些差异不再显著。
结论：这些结果表明，无烟法律是降低无家庭二手烟暴露青少年可替宁的有效策略；然而，在有家庭二手烟暴露的青少年中，未发现有益效果。《儿科学》2010年；126:80 - 87
OBJECTIVES: We investigated the association between smoke-free law coverage and cotinine among nonsmoking youth (3-19 years) with and without home secondhand smoke (SHS) exposure.METHODS: We used data from the 1999-2006 National Health and Nutrition Examination Survey, a cross-sectional survey designed to monitor the health and nutritional status of the US population. Serum cotinine levels were available for 11 486 nonsmoking youth from 117 survey locations. Each location was categorized into 1 of 3 groups indicating extensive, limited, and no coverage by a smoke-free law. Cotinine was analyzed both as a dichotomous (>= 0.05 ng/mL) and as a continuous outcome.RESULTS: Among youth without home SHS exposure, those who were living in a county with extensive coverage of a smoke-free air law had an adjusted 0.61 times (95% confidence interval: 0.48-0.78) the prevalence of detectable cotinine and 0.57 (95% confidence interval: 0.41-0.79) times lower geometric mean compared with youth without a smoke-free air law. Among youth with home SHS exposure, youth with extensive coverage of a smoke-free air law had lower geometric mean cotinine compared with youth who were living in a county without a smoke-free air law, but these differences were no longer observed after adjustment for covariates.CONCLUSIONS: These results suggest that smoke-free laws are an effective strategy for reducing cotinine in youth without home SHS exposure; however, among youth with home SHS exposure, no benefit was detected.
