Introduction:
The prevalence of cigarette smoking is high among U.S. Department of Housing and Urban Development (HUD) assistance recipients, putting others at risk for secondhand smoke (SHS) exposure. We evaluated the burden of SHS exposure among HUD-assisted children, adolescents, and adults.
Aims And Methods:
Using 2007-2018 National Health and Nutrition Examination Survey (NHANES) data linked with HUD administrative data, we assessed SHS exposure prevalence, defined using serum cotinine, among non-tobacco, non-nicotine-using, HUD-assisted children and adolescents (ages 3-17 years, n = 955) and adults (ages ≥ 18 years, n = 878) and among low-income, HUD-unassisted children and adolescents (n = 5788) and adults (n = 8027). Time trends were evaluated. Unadjusted and adjusted multivariable logistic regression models were created to assess SHS exposure by HUD assistance status.
Results:
The prevalence of SHS exposure during 2015-2018 was 73.2% (95% CI = 63.2% to 81.7%) among HUD-assisted children and adolescents and 50.1% (95% CI = 40.1% to 60.1%) among HUD-assisted adults. Decreases in SHS exposure among HUD-assisted individuals from 2007-2010 through 2015-2018 were significant only for ages 12-17 years (78.6% [95% CI = 68.0% to 87.0%] to 64.3% [95% CI = 52.5% to 74.9%]; p = .04). Among low-income individuals, SHS exposure was higher during 2007-2018 among HUD-assisted than HUD-unassisted children and adolescents (OR = 3.39 [95% CI = 2.58 to 4.47]) and adults (2.11 [95% CI = 1.66 to 2.68]). Results remained significant after adjusting for social, demographic, and housing characteristics.
Conclusions:
HUD-assisted children, adolescents, and adults had higher exposure to SHS than those not receiving HUD assistance. SHS exposure among HUD-assisted individuals was high for all years studied, compared to published estimates for the general US population, but did decrease among children and adolescents aged 12-17 years.
Implications:
This study is the first to provide biomarker-derived prevalence estimates of SHS exposure among recipients of HUD assistance within a nationally representative sample of the United States. The findings suggest that HUD-assisted children, adolescents, and adults are an at-risk population for SHS exposure, independent of known confounding social and demographic factors.
