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 (PConclusions: 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.
