Kaviany P, Senter JP, Collaco JM, et al. Spatial analysis of tobacco outlet density on secondhand smoke exposure and asthma health among children in Baltimore City. Tob Control. 2022 Jan 19; tobaccocontrol-2021-056878. Online ahead of print. https://pubmed.ncbi.nlm.nih.gov/35046128/
“Within a 500 m radius of each participant home, there were on average six tobacco outlets. Each additional tobacco outlet in a 500 m radius was associated with a 12% increase in air nicotine (p<0.01) and an 8% increase in serum cotinine (p=0.01). For every 10-fold increase in air nicotine levels, there was a 0.25-point increase in Asthma Therapy Assessment Questionnaire (ATAQ) score (p=0.01), and for every 10-fold increase in serum cotinine levels, there was a 0.54-point increase in ATAQ score (p<0.05).
Increased tobacco outlet density is associated with higher levels of bedroom air nicotine and serum cotinine. Increasing levels of SHS exposure (air nicotine and serum cotinine) are associated with less controlled childhood asthma.”
