n = 302 women with low incomes. WIC, Special Supplemental Nutrition Program for Women, Infants, and Children.
P values were obtained from linear regression models accounting for participation in WIC, accessing the Internet using a phone, and the number of items truly consumed.
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.
