Rules to prohibit the use of electronic vapor products inside homes and personal vehicles among adults in the U.S., 2017

摘要

Most U.S. adults have voluntary rules prohibiting the use of smoked tobacco products in their homes and vehicles. However, the prevalence of similar rules for electronic vapor products (EVPs) is uncertain. This study assessed the prevalence and correlates of rules prohibiting EVP use inside homes and vehicles. Data from a 2017 Internet-based panel survey of U.S. adults aged ≥18?years (n?=?4107) were analyzed. For homes and vehicles, prevalence of reporting that EVP use was not allowed, partially allowed, fully allowed, or unknown was assessed overall and by covariates. Correlates of prohibiting EVP use was assessed by multivariable logistic regression. In homes, 58.6% of adults did not allow EVP use, 7.7% partially allowed use, 10.1% fully allowed use, and 23.6% were unsure of the rules. In vehicles, 63.8% of respondents did not allow EVP use, 6.0% partially allowed use, 8.9% fully allowed use, and 21.4% were unsure of the rules. Following multivariable adjustment, prohibiting EVP use inside homes and vehicles was more likely among respondents with higher income and education, and with a child aged <18?years. Users of EVPs and other tobacco products, and respondents living with users of EVPs and other tobacco products, were less likely to prohibit EVP use in these locations. These findings show that about 6 in 10?U.S. adults have rules prohibiting EVP use inside homes and vehicles, but variations exist by population subgroups. Voluntary smoke-free rules in homes and vehicles that include EVPs can help protect children and non-users from secondhand EVP aerosol exposure.
