Effect of restrictions on smoking at home, at school, and in public places on teenage smoking: Cross sectional study

Abstract

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)...
