Low and high categories split at the median (kg) for those with pesticide exposures greater than 0 within a 400-m radius of the residence. None indicates no pesticide applications were applied within a 400-m radius of the child’s residence.
a
Minimally adjusted for sex and language of survey.
b
Fully adjusted for sex, language of survey, health insurance, parent/guardian education, and exposure to environmental smoking.
