Although food insecurity is more prevalent in households with smokers, no studies have examined the misclassification of children's secondhand smoke (SHS) exposure by household food security status. Our population‐based sample included 8453 participants (3‐12y) in the National Health and Nutrition Examination Survey 1999‐2010. Food security status was assessed by the USDA 18‐item Food Security Survey Module. Self‐reported SHS exposure by household reference participants were compared to children's serum cotinine levels. Serum cotinine levels of 蠅0.05 ng/ml were indicative of SHS exposure. Logistic regression models were used to estimate the association between household food security status and misclassification of SHS exposure. Controlling for age, gender, and race/ethnicity, children who were food insecure (Odds Ratio 1.3; 95% CI, 1.1‐1.6) were more likely to have their SHS exposure misclassified, compared to their fully food secure counterparts. The association was attenuated when family income was included in the model. In conclusion, regardless of food security status, household reference participants' reports of SHS exposure among children, especially food insecure children, may be biased.
