What this trial studies

This study evaluates the effectiveness of social transfers on exclusive breastfeeding rates among new mothers in São Paulo, Brazil. Participants will be randomly assigned to one of three groups: a control group with no social transfer, a group receiving a non-conditional social transfer at six months postpartum, and a group receiving a conditional social transfer based on their exclusive breastfeeding status. All participants will receive education on the benefits of exclusive breastfeeding and current international recommendations. The study aims to determine the impact of these interventions on breastfeeding duration and child health and development.
