What this Trial Is About
Researchers are studying the impact of social transfers on exclusive breastfeeding rates in São Paulo, Brazil. The study aims to find out if providing social transfers can increase exclusive breastfeeding rates, extend the duration of exclusive and complementary breastfeeding, and improve long-term child health and development. Participants are mothers who have recently given birth and are breastfeeding exclusively. Participants are randomly assigned to one of three groups: a control group receiving only educational materials about breastfeeding benefits and recommendations; a non-conditional social transfer group receiving gifts at six months postpartum regardless of breastfeeding status; and a conditional social transfer group receiving gifts only if they are still exclusively breastfeeding at six months. Gifts include options such as diapers, hygiene products, toys, or transport vouchers. Throughout the study, researchers will compare breastfeeding rates and durations at six months postpartum among groups. Child health and early development will be assessed at 1 month, 6 months, 1 year, and 2 years. Mothers will receive education about breastfeeding benefits at baseline. The study will track exclusive and complementary breastfeeding patterns as well as child developmental outcomes over two years.
