About the Talk

In the US 41% of children (aged 3-11) and 34% of adolescents (aged 12-19) are exposed to secondhand tobacco smoke with considerable racial and ethnic disparities in exposure. Although a number of individual-level determinants of this disparity have been identified, its contextual determinants remain largely unexamined. We used log-normal regression models to examine disparities in serum cotinine in relation to Metropolitan Statistical Areas (MSA) level income inequality among 14,649 non-smoking children aged 3-15 from the National Health and Nutrition Examination Survey (1999-2012). Within areas with low income inequality, non-Hispanic black children had significantly lower serum cotinine concentrations than non-Hispanic white children (-0.26; 95% CI: -0.38, -0.15). However, within areas with high income inequality, average serum cotinine levels for non-Hispanic black and non-Hispanic white children were the same (0.01; 95% CI: -0.16, 0.18). In contrast, cotinine concentrations remained significantly lower among Mexican-American compared to non-Hispanic white children in all areas. Both non-Hispanic white and Mexican American children evinced a pattern of decreasing serum cotinine levels with increasing income inequality. In contrast, serum cotinine levels of non-Hispanic black children did not change as a function of the level of income inequality. Our findings add to the evidence suggesting that health effects of income inequality are likely to be race-specific.
