Abstract

Background It is well established that secondhand smoke (SHS) is harmful, and concern about the potential dangers associated with secondhand vapour (SHV) (ie, vapour from electronic vapour products, EVP) is growing. The present study examines the prevalence and characteristics associated with SHS and SHV exposure. Methods Data from youth aged 11-17 who completed the 2016 Florida Youth Tobacco Survey (n=58 616) were analysed. Demographics, past 30 day SHS and SHV exposure, environmental factors, cigarette and EVP use status, SHS and SHV harm perceptions, and tobacco susceptibility were assessed. Weighted multivariable logistic regressions were performed to examine characteristics associated with SHS and SHV exposure, and SHS and SHV exposure with tobacco susceptibility. Results Overall, 42% of Florida youth reported SHS exposure and 29% reported SHV exposure during the past 30 days. Living in a home where tobacco use was permitted (vs not permitted) was positively associated with SHS (adjusted OR (AOR) 2.57) and SHV exposure (AOR 1.56). Perceived SHS as harmful (vs not harmful) was positively associated with SHS (AOR 1.73) and SHV exposure (AOR 1.97), while perceived SHV as harmful was negatively associated with SHS (AOR 0.86) and SHV exposure (AOR 0.56). SHS and SHV exposure was significantly associated with susceptibility to cigarette and EVP use (AOR 1.40 and 2.08, respectively). Conclusions Almost one-third of Florida youth reported SHV exposure. Factors associated with SHS and SHV exposure are somewhat similar, and exposure to SHS and SHV is associated with tobacco susceptibility in youth. Promoting tobacco-free homes is needed to protect youth from SHS and SHV exposure.
