² P values were obtained from linear regression models accounting for participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), accessing the Internet using a phone, and the number of items truly consumed.

³ P values were obtained from Poisson regression models accounting for participation in WIC, accessing the Internet using a phone, and the number of items truly consumed.
