Mauricio Lima Barreto from Fiocruz in Brazil will evaluate the impact of social and economic inequalities, and the national family allowance program (Bolsa Familia), on healthy births and early childhood health and development. They will setup a cohort, which will be derived from a central database of named households created to support Brazil's social programs, and a data center for the analysis. They will use a variety of demographic, economic and social data on families, as well as information on births and childhood deaths, and child growth.
