[Breast feeding habits in marginated neighborhoods in Guadalajara].

They were analyzed the reasons for avoiding or interrupting the breast feeding habits of infants. We included 701 pairs mother-child, who belonged to the marginal neighborhoods of Guadalajara City. Through an interview, it was gotten information about family, socioeconomic and demographic characteristics, and feeding patterns. In addition, it was carried out anthropometric measurements to all children for the evaluation of the nutritional status. Mothers with lower schooling (P less than 0.05), lower levels of life (P less than 0.01), higher parity (P less than 0.01), and with no social security had the higher prevalence of breast feeding practices. Insufficient production was the major cause of avoiding or interrupting breast feeding (65 and 35% respectively). Infant rejection of the breast milk was, the second cause in both cases, (7.6 and 21.6% respectively). Most of the cases, insufficient production and infant rejection of breast milk is due to defects on feeding techniques. Therefore, it is necessary to give more support and advise to the mother who is willing to breast feed her child. Breast feeding; interruption of; causes of; in marginal neighborhoods.
