Introduction. The Baby Friendly Hospital Initiative (BFHI) was idealized by WHO and UNICEF to promote, protect and support breastfeeding in the hospital sphere. The Rede Amamenta Brasil was created by Ministry of Health with the same objective; however, in the primary health care sphere. Objective. To evaluate the influence of support offered by maternity hospitals and ambulatory attendance places on breastfeeding pattern in children less than six months in the city of Ribeirão Preto, SP, Brazil. Methods. Dates related to maternity hospitals characterization and implementation of IHAC's "Ten Steps to Successful Breastfeeding" were collected during an interview with responsible doctor by the neonatology service of each place. Information about Rede Amamenta Brasil - participation on Oficina de Trabalho em Aleitamento Materno - was given by City's Secretary of Health. Characteristics of children, their mothers, birth hospital and ambulatory attendance place were obtained by Projeto Amamentação e Municípios 2011. The effect of factor study on exclusive (EB) and predominant (PB) breastfeeding was evaluated by Poisson multiple regression analysis with robust variance. Variables with p<0,20 and that modified in more than 10% prevalence ratio of factor study were included in the multiple model. Results. The number of studied children was 916. The most part (58.9%) was born by Cesarean delivery. The prevalence of EB was 33.2%, and PB, 16.3%. Among seven maternity hospitals of the studied city, three are public and accredited by BFHI. Among 40 primary care units, 15 made the Oficina da Rede. Total number of met steps for each maternity hospital range from 1 to 10, and only one place met all steps. The prevalence of EB was higher when step referred to no offer artificial teats or pacifiers was met. The prevalence of PB tended to increase when the number of met steps raised, and the step related to breastfeeding support groups increased this prevalence. The EB was more prevalent in places that realized the Oficina da Rede. Conclusions. Meeting higher number of steps showed ascendant trend on increasing prevalence of PB in children less than six months. The step 10 also increase this prevalence, and the step 9 increase the prevalence of EB. This outcome was more prevalent in places that participated of the Oficina da Rede. The findings of this study can be useful to other places encourage breastfeeding.
