title: [The influence of breastfeeding in the hospitalization of children under two years of age in the State of Pernambuco, Brazil, in 1997 and 2006].
abstract: The scope of this paper was to evaluate the influence of breastfeeding and other factors on the incidence of hospitalization and the frequency and main causes of hospitalization in children under two years of age in the State of Pernambuco. It is a cross-sectional, descriptive-analytical study using secondary data obtained from the II and III State Health and Nutrition Surveys (PESN) carried out in 1997 and 2006, respectively. A sample of 1503 infants under two years of age was studied. Pearson's Chi-square test was used to analyze bivariate associations and Fisher's exact test for comparison of risk of hospitalization in the two years of observation and Poisson regression for the adjustment of the multivariate model of hospitalizations in the last survey. In the two years analyzed, there was no statistically significant difference in the percentage of hospitalizations of children. The lower risk of hospitalization remained for those who were breastfed exclusively. Regarding to environmental, socioeconomic, demographic characteristics and health assistance, several factors have evolved favorably in the period assessed. In the final model, only the weight/length ratio (low weight category) remained associated with the risk of hospitalization in children under two years of age factors.
