[Child health in poor areas of North and Northeast Brazil: a comparison of areas covered by the Children's Mission and control areas].

Community surveys are essential to estimate health indicators, evaluate health programs, and define health interventions. In 2002, a cross-sectional survey of children under five was conducted in 18 areas of the poorest counties in North and Northeast Brazil. Nine areas were visited by volunteer community health workers (CHW) under the Children's Mission, and the others were not visited. Using a standard questionnaire, trained interviewers collected information at the household level for 1,528 children, 782 of whom were visited monthly by CHWs and 772 were not. All the children and their families were living below the poverty line; 40.0% of the parents were illiterate, per capita daily income was about US$0.30, and household conditions were substandard. However, most were living less than 1km from a public health service and almost all children who were referred to these services received medical care. Prenatal care was also poor in terms of number of medical visits and laboratory tests. Children visited by CHWs from the Children's Mission received better care in terms of growth monitoring, number of medical check-ups, and prenatal iron supplementation.
