Cotinine-Measured Secondhand Smoke Exposure Among Federal Housing Assistance Recipients Without Active Tobacco or Nicotine Use in the United States: NHANES, 2007–2018

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.
