Public primary health care and children's health in Brazil: evidence from siblings

The Family Health Program (Programa SaA(0)de da Familia) is an initiative of the Brazilian Ministry of Health designed to deliver free primary health care services within communities and households. The program was implemented by municipalities in different periods of time, creating variation in its availability among siblings of different ages. The empirical approach uses this variation to estimate the effect of the program on children's health in Brazil, in an attempt to control for family and municipality unobserved factors possibly related to the program's adoption. The results indicate that children for whom the Family Health Program was available in their municipalities during the prenatal period are healthier than children for whom the program was not available during the same period of their lives.
