Abstract

Early weaning is still present in society and is characterized by the introduction of other foods or liquids during the period of exclusive breastfeeding. This problem interferes with the economic situation of the newborn's family, with an impact on food. The present study aimed to analyze survival and risk factors associated with the prevalence of early weaning in infants under six months of age in Mozambique. Data from the 2011 demographic and health survey IDS conducted in Mozambique were used. A statistical analysis was performed with the application of survival analysis techniques, applying the Kaplan-Meier tests, log-rank and Cox regression model. It was found that 26,3% of the children studied stopped being exclusively breastfed before six months of life, and the overall survival rate for early weaning at one month was 97,7%  decreasing to 73,7% at six months. The following covariables were shown as protective factors for early weaning: sex of the child, place of residence and incidence of diarrhea in children, and as a risk factor level of education of the mother. The study shows that, intervention measures are necessary to increase the rates of exclusive breastfeeding directed at women with higher education, as well as clarifications about milk forms, myths about breastfeeding, the rights conquered in relation to work, should be prioritized themes.
