This study will be conducted in collaboration with Antelope Valley Partners for Health, who will deliver a home visitation program intervention once a week for 24 months. Two-hundred-and-forty overweight/obese Hispanic mothers and their infants will be recruited. They will be randomly assigned to: group 1, a standard home visitation program only; group 2, a standard home visitation program that incorporates sugar reduction; and group 3, a standard home visitation program that incorporates sugar reduction with home water delivery. The main outcomes are maternal BMI and infant weight-for-length growth. We will also assess maternal and infant diet using 24-hour recalls, and maternal feeding style and infant eating behaviors using questionnaires. Linear mixed effects models will be used to compare changes between the intervention groups in maternal BMI and infant weight-for-length.
