*Survey procedures were used to account for the NHANES survey design and to obtain population weighted estimates for prevalence and OR estimates. OR estimates were based on logistic models adjusted for age, sex, race/ethnicity, poverty to family income ratio, body mass index percentile, current asthma and total Healthy Eating Index score.
