A bivariate analysis was initially developed between each exposure variable and outcome (Table 1). The following exposure variables were considered: 1. performance score (in tertiles); 2. model of assistance (basic health unit vs. family unit); 3. help from the maternity ward staff (yes

vs. no); 4. maternal employment (yes ZD6474 ic50 vs. no); 5. child’s age (younger than 3 months vs. 3 to 6 months). Chi-squared hypothesis tests were performed and crude prevalence ratios (PR) were obtained with their respective 95% confidence intervals (95% CI). Exposure variables that in the bivariate analysis were associated with the outcome with p-value less than or equal to 20% in the chi-squared test were selected

for the multivariate analysis. The final model used to estimate measures of association, with their respective 95% CIs, consisted of the exposure variables that had a p-value less than or equal to 5%, and the child’s age was analyzed as a continuous variable (Table 2). The adjusted prevalence ratios were obtained by Poisson regression with robust variance, as the outcome showed a high prevalence.15 A total of 56 units Saracatinib were evaluated, of which 28 were basic health units and 28 were family health units. Two initially sampled family health units were not analyzed, because one had recently been deactivated, and the other could not be visited for public safety reasons. Of these 56 analyzed and sampled units, two already had the title of “Breastfeeding-Friendly Primary Care Unit”. The best performing unit had a score of 9.38, and the worst performance unit, of 3.00, with a median score of 5.62. The most often completed steps (Fig. 1) were step 5 (Instruct pregnant women about the importance of breastfeeding in the first hour after birth and of keeping the baby in the same room as the mother), step 4 (Listen to the concerns, experiences, and questions of pregnant women and mothers on breastfeeding practice, supporting them and strengthening their self-confidence), Anidulafungin (LY303366) and step 3 (Instruct pregnant

women and mothers on their rights and the benefits of breastfeeding, promoting EBF until 6 months of age and supplemented breastfeeding up to 2 years of age or older). Step 1 was the least completed (Have a written policy regarding the promotion, protection, and support of breastfeeding, to be routinely communicated to all staff of the health unit). At the weigh-in in the pre-consultation, data were collected from 4,092 children in the first 6 months of life. A prevalence of 47.6% of EBF was found among children younger than 6 months who were followed up at the primary healthcare. This practice comprised 76.1% of children in the first month of life, 51.7% in the third month of life, and only 17.5% in the sixth month of life.
