Smoke-Free Multi-unit Housing Policies Show Promise in Reducing Secondhand Smoke Exposure Among Racially and Ethnically Diverse, Low-Income Seniors

Abstract

Secondhand smoke (SHS) exposure is a public health issue for residents of multi-unit housing (MUH) properties. We evaluated the impact of smoke-free policy implementation on reported SHS exposure among racially, ethnically diverse seniors living in low-income MUH properties. In Spring 2013 and Summer 2014, we surveyed residents (n = 960) at 15 MUH properties in Broward and Miami-Dade Counties, Florida. The percentage of residents reporting SHS exposure within their apartments from elsewhere in or around their building decreased from 31.1 %, before policy implementation, to 23.6 % at follow-up (p = 0.02). In multivariate analysis of non-smoking residents after policy implementation, residents who reported having one or more comorbidities were two times more likely to report SHS exposure (aOR 2.23, 95 % CI 1.12–4.40). Considering the vulnerability of low-income seniors to SHS exposure, our findings are relevant to residents, property owners/managers, and public health professionals making decisions about smoke-free policies for MUH properties in which seniors reside.
