SALURBAL (Urban Health in Latin America) is a study that examines how urban environments and policies impact the health of residents living in cities of 100,000 inhabitants or more in Argentina, Brazil, Colombia, Costa Rica, Guatemala, El Salvador, Mexico, Panama, and Peru. Within this project, the Maternal, Perinatal, Child, and Adolescent working group (MAPECA) focuses on generating evidence on the social and health disparities among women, children, and youth to inform local strategies that contribute to build healthier, more equitable and sustainable cities in the region.
