Trial Summary

What is the purpose of this trial?The purpose of this study is to determine whether a health education program incorporating sugar sweetened beverage and juice (SSB/J) reduction and home water delivery affects maternal and infant risk for obesity by randomizing mother-infant dyads to one of three 24-month interventions: Group 1 (control): standard health education program only; Group 2 (translation): health education program focused on sugar reduction; and Group 3 (efficacy): health education program focused on sugar reduction and bottled water delivery.
