Factors Related to a Smoke-free Home Status: A Parental Report

The household smoking ban is one potential strategy for reducing exposure to second-hand smoke at home. There is little information about whether concurrent alcohol and tobacco use are related to a smoking ban at home. This study aimed to examine the association between concurrent alcohol and tobacco use with the household smoking ban strategy as reported by the parents of schoolchildren.

We used data from a cross-sectional study that surveyed schoolchildren at 9 schools (grades 6 to 8). A self-administered questionnaire was sent out to the parents of 1,335 schoolchildren. Household smoking ban status was reported by the parents. We used multiple logistics regression to investigate the association between the household smoking ban and alcohol and tobacco use adjusted for potential confounders.

The prevalence of a no-smoking ban in households was 51% (95% confidence interval: 48.4%, 53.8%). After adjusting for the number of smokers in a home and perceptions about the harm of exposure to second-hand smoke, the multiple logistics regression results showed that concurrent alcohol and tobacco use in the households (OR = 2.31; 95% CI: 1.66, 3.20) had a higher risk of a no-smoking ban.

Our findings showed that concurrent alcohol and tobacco use was associated with a smoking ban status in households. A no-alcohol-drinking-at-home campaign should be adopted and promoted for increasing the rate of smoke-free homes.
