  • OR indicates odds ratio; CI, confidence interval.

  • a Adjusted by multivariate logistic regression for state of residence, child's age, gender, race/ethnicity, primary language spoken at home, household composition, metropolitan/nonmetropolitan residence, and household poverty status or household education.

  • b The χ2 test for the overall association between the covariate and secondhand smoke exposure was statistically significant at P < .01.
