King, Armour BrianAbstractPrivate settings are major sources of secondhand smoke (SHS) exposure among youth. We measured prevalence and correlates of youth exposures to home and vehicle SHS. The 2016 National Youth Tobacco Survey of U.S. 6th–12th graders was analyzed (n = 20,675). Past-7-day home or vehicle SHS exposures were self-reported. Descriptive and multivariable analyses were performed on weighted data. Among all students, past-7-day SHS exposures were: vehicle (21.4%, 5.56 million); home (21.7%, 5.64 million); home or vehicle (29.0%, 7.50 million); vehicle and home (14.0%, 3.63 million). By household tobacco-use status, home or vehicle SHS exposure was: tobacco-free households, 8.4%; households with combustible-only tobacco users, 59.8%; households with smokeless tobacco/e-cigarette-only users, 21.8%; and households with combined tobacco products usage, 73.9%. Where only the youth respondent but no other household member(s) used tobacco, the measure of association (vs. tobacco-free households) was ~two-fold higher for vehicle SHS exposures (Adjusted Odds Ratio [AOR] = 6.09; 95% Confidence Interval [CI] = 4.93–7.54 than for home SHS exposures (AOR = 3.16; 95%CI = 2.35–4.25). Conversely, where only household member(s) but not the youth respondent used tobacco, the measure of association was over two-fold higher for home SHS ...
