背景研究的影响，苏格兰无烟立法对社会不平等的二手烟（SHS）暴露在小学children.Methods全国代表性的比较，横截面，以班级为基础的调查在同一所学校之前和之后的立法。参与者是2532名小学生（小学7年级;年龄约11岁）在2006年1月（立法前）和2389年1月（立法后）进行了调查。结果调整吸烟父母数量后，家庭SEC和FAS组的平均可替宁浓度差异显著，且从高到低的家庭SEC/FAS显著逐步增加。立法后，所有家庭SEC/FAS组的平均可替宁下降。所有家族SEC/FAS组中平均可替宁的相对下降相等。添加调查年和家庭SEC/FAS的模型之间的相互作用项显示，随着时间的推移，不平等的增加，但只有在93%的水平使用FAS和73%使用家庭SEC的显着。结论SHS暴露的不平等存在于11岁的儿童在苏格兰。无烟立法减少了所有儿童对SHS的暴露。虽然在最低SEC/FAS组中观察到可替宁的绝对减少最大，但该组的可替宁水平仍然最高，并且有可能增加不平等，这可能需要长期监测。
Background To examine the impact of the Scottish smoke-free legislation on social inequalities in secondhand smoke (SHS) exposure among primary school children.Methods Comparison of nationally representative, cross-sectional, class-based surveys carried out in the same schools before and after legislation. Participants were 2532 primary school children ( primary 7; aged around 11 y) surveyed in January 2006 ( before legislation) and 2389 in January 2007 ( after legislation). Outcome measures were salivary cotinine concentrations, self-reported family socioeconomic classification ( family SEC) and family affluence scale (FAS).Results After adjusting for number of smoking parents, mean cotinine concentration varied significantly across both family SEC and FAS groups, and increased significantly stepwise from high to low family SEC/FAS. Mean cotinine fell in all family SEC/FAS groups after legislation. The relative drop in mean cotinine was equal across all family SEC/FAS groups. Adding an interaction term between survey-year and family SEC/FAS to the model showed an increase in inequalities over time, but was only significant at the 93% level using FAS and 73% using family SEC.Conclusion Inequalities in SHS exposure exist among 11-year-old children in Scotland. Smoke-free legislation has reduced exposure to SHS among all children. Although the greatest absolute reduction in cotinine is observed in the lowest SEC/FAS group, cotinine levels remain highest for this group and there is a suggestion of possible increases in inequalities, which may warrant longer-term monitoring.
