^*Prevalence is too low to estimate result.

Logistic regression models with robust standard errors were used to estimate marginal probabilities and 95% CI for each binary outcome variable adjusted for parental education, race/ethnicity, age, sex, and potential clustering by school. Similarly adjusted multiple regression models with robust standard errors were used to estimate means and 95% CI for mean number of breakfast, lunch, and dinner outcomes.
