The Baby-Friendly Hospital Initiative: increasing breastfeeding and decreasing infant mortality in Brazil

Objectives: to estimate the population attributable fraction of preventable infant mortality rates due to changes in breastfeeding (BF) indicators attributable to the Baby Friendly Hospital Initiative (BFHI). Methods: an estimate on the impact of BFHI in reducing infant mortality with an inferential level of plausibility, using secondary data from the II Breastfeeding Prevalence Survey of 2008. Initially, the effect of BFHI on breastfeeding in the first hour of life, exclusive breastfeeding, and any breastfeeding based on the prevalence of the outcomes among infants born in BFHI or non-BFHI was calculated. Second, the population attributable fraction of nonbreastfeeding was estimated for late neonatal mortality, mortality by all causes and infant mortality by infections, for BFHI and non-BFHI, and the number of potentially avoidable deaths if all children were born in BFH. Results: reduction of 4.2% of late neonatal deaths due to the increase in BF prevalence in the first hour, as provided by BFHI. BFHI potentially contributed with 3.5% of all-cause deaths and 4.2% of deaths from infection by BF promotion in infants below 6 months. Conclusions: the reduction of mortality in children between 7 and 180 days in 2008 potentially attributable to BFHI through the promotion of BF indicators reinforces the importance of strengthening and expanding this initiative in Brazil to ultimately enhance child survival.
