¹n=8(1.2%) had missing gender data; n=4 White, n=4 African-Americans

²n=10 individuals (1.5%) had missing age data; n=4 White, n=6 African-Americans

³n=81 (13.1%) households had missing income data; n=48 White, n=33 African-American

⁴29 individuals (4.4%) had missing data on asthma; n=13 White, n=16 African-Americans

⁵30 individuals (4.5%) had missing data on allergic rhinitis; n=13 White, n=17 African-Americans

⁶n=29 individuals (4.4%) had missing data on eczema; n=12 White, n=17 African-Americans

⁷Odds ratios represent the probability of the italicized row outcome in comparison to White children (reference group), adjusted for demographic covariates. Adjusted ratios for income are based on probability of earning >= $100k in comparison to < $50k; ratios for asthma model are based on having asthma versus not.

Bold values represent statistical significance;

^*P < 0.05;

^**P < 0.01;

^***P < 0.001

Percentages may add to over 100 due to rounding
