Household tobacco smoke exposure and acrylonitrile metabolite levels in a US pediatric sample

This study seeks to determine if members of a pediatric (<18 years) sample who have high levels of the urinary volatile organic compound (VOC) metabolite of acrylonitrile, N-Acetyl-S-(2-cyanoethyl)-L-cysteine (CYMA), are significantly more likely to be living in a household with indoor tobacco smoke exposure. A weighted logistic regression was used to compare pediatric participants in the highest quartile of CYMA levels (? 4.56 ng/mL) with those whose CYMA levels were not in the highest quartile. 411 pediatric participants were identified in the NHANES data for analysis. Those in the highest quartile of recorded CYMA values were more likely to be living with active indoor smokers (69.35 %) than those who were not in the highest quartile (32.72 %). Having one indoor smoker (adjusted-OR: 2.53, 95 % CI: 1.01?6.34) or 2+ indoor smokers (adjusted-OR: 4.25, 95 % CI: 1.84?9.81) were both associated with a pediatric participant having a CYMA value in the highest quartile.

Automated summary

The study found that pediatric participants with high levels of the CYMA metabolite were more likely to be living in households with indoor smokers. Those in the highest quartile of CYMA levels were more likely to have exposure to indoor tobacco smoke.
