背景：虽然无烟餐厅法律旨在保护公众免受二手烟的影响，但它们也可能会阻止青少年吸烟。没有来自纵向研究的证据来验证这一假设。目的：检验当地餐馆吸烟法规对青少年吸烟进展的影响。设计、设置和对象：2001-2002年间，通过随机数字拨号电话调查访问了2623名12-17岁的马萨诸塞州青少年，并在两年后进行了跟踪调查。使用广义估计方程(GEE)Logistic回归分析控制潜在的个人、家庭和城镇层面的混杂因素。主要观察指标：在两年的随访期内进展为吸烟(定义为一生中吸烟100支或更多)。结果：与居住在法规薄弱城镇的年轻人相比，居住在法规严格的城镇(全面禁止餐馆吸烟)的年轻人进展到吸烟的几率不到一半(优势比(OR)0.39，95%可信区间(CI)0.24至0.66)。在实施了两年或更长时间的严格规定的城镇中，这种关联性更强(OR 0.11，95%CI 0.03至0.37)，但在那些实施不到两年的严格规定的城镇中，这种联系仍然存在(OR 0.55，95%CI 0.33至0.90)。未发现居住在中等餐馆吸烟规定(限制在封闭的、单独通风的区域吸烟)的城镇与吸烟进展到既定吸烟率之间的关系。结论：当地餐馆禁烟可能是预防青少年吸烟的有效干预措施。
Background: While smoke-free restaurant laws are intended to protect the public from secondhand smoke exposure, they may also discourage smoking among adolescents. There is no evidence from longitudinal studies to test this hypothesis.Objective: To examine the effect of local restaurant smoking regulations on progression to established smoking among adolescents.Design, setting, and subjects: A cohort of 2623 Massachusetts youths, ages 12-17 years at baseline, was interviewed via random digit dial telephone survey in 2001-2002 and followed up two years later. A generalised estimating equations (GEE) logistic regression analysis was used and controlled for potential individual, household, and town level confounding factors.Main outcome measure: Progression to established smoking during the two year follow up period (defined as having smoked 100 or more cigarettes in one's life).Results: Compared to youths living in towns with weak regulations, those living in towns with strong regulations (complete restaurant smoking bans) had less than half the odds of progression to established smoking (odds ratio (OR) 0.39, 95% confidence interval (CI) 0.24 to 0.66). The association was stronger for youths in towns with strong regulations in effect for two or more years (OR 0.11, 95% CI 0.03 to 0.37), although it was still present for those in towns with strong regulations in effect for less than two years (OR 0.55, 95% CI 0.33 to 0.90). No relationship was found between living in a town with a medium restaurant smoking regulation (restriction of smoking to enclosed, separately ventilated areas) and rates of progression to established smoking.Conclusions: Local restaurant smoking bans may be an effective intervention to prevent youth smoking.
