目的探讨家庭、学校和公共场所限制吸烟程度与在校学生吸烟摄入量和吸烟率的关系，设计公共场所限制吸烟程度合并记录的横断面调查。背景是美国。研究对象17287名高中生，主要结果测量：吸烟吸收五分制；结果：在家中吸烟的限制性安排越多，处于早期吸烟阶段的可能性越大（P < 0.05）， 30天患病率越低（优势比0.79(95%可信区间0.67 ~ 0.91),P < 0.001）。这些发现甚至适用于父母吸烟的情况。在公共场所更普遍地限制吸烟与处于早期吸烟阶段的可能性更高（P < 0.05）和较低的30天患病率相关（0.91(0.83至0.99),P = 0.03）。学校禁烟令与更有可能处于早期吸烟阶段（0.89(0.85至0.99)，P< 0.05）和更低的流行率（0.86(0.77至0.91)，P< 0.001）有关，只有当禁令得到强有力的执行时，通过青少年认为大多数或所有学生都遵守规定的情况来衡量。这些发现表明，在家中限制吸烟，在公共场所更广泛地禁止吸烟，以及在学校强制禁止吸烟可能会减少青少年吸烟。
Objective To determine the relation between extent of restrictions on smoking at home, at school, and in public places and smoking uptake and smoking prevalence among school students,Design Cross sectional survey with merged records of extent of restrictions on smoking in public places.Setting United States.Participants 17 287 high school students,Main outcome measures Five point scale of smoking uptake; 30 day smoking prevalence,Results More restrictive arrangements on smoking at home were associated with a greater likelihood of being in an earlier stage of smoking uptake (P < 0.05) and a lower 30 day prevalence (odds ratio 0.79 (95% confidence interval 0.67 to 0.91), P < 0.001). These findings applied even when parents were smokers. More pervasive restrictions on smoking in public places were associated with a higher probability of being in a earlier stage of smoking uptake (P < 0.05) and lower 30 day prevalence (0.91 (0.83 to 0.99), P = 0.03). School smoking bans were related to a greater likelihood of being in an earlier stage of smoking uptake (0.89 (0.85 to 0.99), P < 0.05) and lower prevalence (0.86 (0.77 to 0.91), P< 0.001) only when the ban was strongly enforced, as measured by instances when teenagers perceived that most or ail students obeyed the rule.Conclusions These findings suggest that restrictions on smoking at home, more extensive bans on smoking in public places, and enforced bans on smoking at school may reduce teenage smoking.
