[Implementation and impact of the National Iron Supplementation Program in the city of Viçosa, State of Minas Gerais].

The scope of this work was to evaluate the implementation of the National Iron Supplementation Program (NISP) in Viçosa in the State of Minas Gerais and its impact on 6- to 18-month-old non-anemic infants assisted by the Family Health Teams. Interviews were conducted with the professionals and with the children's mothers/guardians. The non-anemic children who didn't receive the earlier supplementation (n=133) were given ferrous sulphate syrup for six months. Hemoglobin dosage, anthropometric evaluation and a socioeconomic survey were conducted before and after the six-month period. Children who ingested 75% or more of the prescribed dosage were classified as high adhesion, while the others were classified as low adhesion, according to the mothers' testimonials. With respect to the implementation in the city, the distribution system was not always available to the priority group and there was a lack of training and motivation on the part of most Community Health Agents. The lack of promotion of NISP among the priority group was detected, apart from a mothers' awareness drive. Regarding diet supplementation, children showed low adhesion and the dosage wasn't effective in preventing anemia. Therefore, important operational barriers to implementation were observed.
