Impact of parental home smoking policies on policy choices of independently living young adults

摘要

Objective: To determine whether adolescents living inrnparental homes where smoking is banned are more likelyrnto move into smoke-free living quarters when they leavernhome.rnMethods: We analysed data on 693 youths from a 4-rnyear, three-wave prospective study of a representativernsample of Massachusetts adolescents (aged 12-17). Allrnyouths resided in independent living quarters at follow-up.rnThe primary outcome was presence of a smoking ban inrnthe living quarters at follow-up. The primary predictor wasrnpresence of a household smoking ban in the parentalrnhome, assessed 2 years before the outcome. Generalisedrnlinear mixed effects models examined the effect of arnparental household smoking ban on the odds of movingrninto smoke-free living quarters at follow-up overall andrnstratified by smoking status at follow-up.rnResults: Youths leaving home had much higher odds ofrnmoving to smoke-free living quarters if their parentalrnhousehold had had a smoking ban (odds ratiorn(OR) = 12.70, 95% CI, 6.19 to 26.04). Other independentrnpredictors included moving into a school or collegernresidence (OR = 3.88, 95% Cl 1.87 to 8.05), and not livingrnwith smokers at follow-up (OR = 3.91, 95% Cl 1.93 torn7.92).rnConclusions: A household smoking ban in the parentalrnhome appears to lead youths to prefer smoke-free livingrnquarters once they leave home.
