Associations of Child PON1 and Genetic Ancestry with Obesity Parameters at Ages 2 and 5.

PON1₁₉₂ coded as number of Q alleles, 0, 1 or 2.

Proportional African ancestry was log transformed to normalize the distribution.

Children were considered obese if their BMI was at or above 95^th percentile of the 2000 CDC sex-specific BMI-for-age growth charts.

Using a Bonferonni correction for multiple testing (5 tests per model), we considered p-values less than 0.01 to be statistically significant.
