Note: Separated quantile regression models were fit with total daily energy intake, daily carbohydrate intake, daily fat intake, daily protein intake, daily sugar intake, daily fruit intake, and daily vegetable intake as dependent variables, and snacking frequency as independent variables, controlled for age, gender, race/ethnicity, and maternal educational level.
