The Association Between Household Smoking Restrictions and Smoking Abstinence: Does Age Matter?

AbstractAim:The purpose of this study is to explore how effective household smoking restrictions (HSRs) are in different age groups in predicting smoking abstinence. Methods:The study analysed the Canadian Community Health Survey (CCHS) cycle, 3.1. Smoking abstinence was defined as individuals who reported to not have smoked greater than 100 cigarettes (n= 1 024 578) and were selected for this analysis. Important covariates include sex, age, education and immigrant status. Logistic regression was used to assess the association between smoking household restrictions and smoking abstinence when taking covariates into consideration. Results:Individuals who implemented HSRs reported to be abstinent from smoking at 12% compared to those with no HSRs at 0.7%. When adjusted for covariates of interest, the odds ratio (OR) for smoking abstinence was 1.43 (95% confidence interval (CI): 1.04, 1.97; P < .026). It was found that age was a strong predictor of smoking abstinence particularly in youths at 3.11 (95% CI: 1.65, 5.84; P < .001) and young adults at 1.92 (95% CI: 1.44, 1.92; P < .001). Conclusion:It is suggested that HSRs is an important anti-tobacco socialisation tool in youths and young adults. Individuals living in a home with HSRs may internalise behavioural norms against the initiation or continuation of smoking.
