title: [Factors affecting the duration of maternal breast-feeding in a cohort of urban mothers studied longitudinally].
abstract: A prospective study on the incidence and duration of breastfeeding in a cohort of urban women of the city of Tlaxcala was carried-out in a private pediatric clinic from January, 1983 to December, 1987. In a total of 547 women studied, breastfeeding had a median of three months, and only 5% of the children continued to be breastfed at one year of age. Family tradition of breastfeeding, late introduction of solid foods and/or whole milk and less formal education of the mother were factors related with breastfeeding beyond three months. About 70% of the mothers weaned their children claiming a rejection of the breast-milk by the child, a lack of sufficient quantity to fulfill the child's needs or because of their work outside the home.
