RESUMEN
OBJECTIVE: To identify the frequency and median duration of breast-feeding in children aged 0-24 months in the city of Ouro Preto, Brazil. METHODS: A cross-sectional study was carried out to identify the median duration of breastfeeding in children aged 0-24 months. A sample of 229 children from 1800 households was drawn by clusters at three different occasions and stratified according to the area (urban or rural). The frequency and median duration of breast-feeding were calculated using the life table technique. RESULTS: A median duration of 198 days was found for breast-feeding as a whole: 71 days for the group of exclusive plus mainly breastfeeding and 17 days for exclusive breastfeeding. CONCLUSION: The current pattern of breast-feeding is of a short-term practice. This evidence suggests the need for intervention programs to promote breast-feeding for longer periods and delay the introduction of food supplementation, preventing the early weaning.
