Promo？？o, prote？？o e apoio à amamenta？？o na aten？？o primária à saúde no Estado do Rio de Janeiro, Brasil: uma política de saúde pública baseada em evidência

this article evaluates a policy for breastfeeding promotion, protection, and support in primary health care units in rio de janeiro state, brazil, analyzing the assumptions, interventions, and results based on a log-frame model. a systematic review sought to identify effective procedures and strategies for extending breastfeeding duration, constituting the basis for creating "ten steps" in the "breastfeeding-friendly primary care initiative" launched in rio de janeiro state in 1999. a corresponding evaluation method was developed and applied to verify the performance of 24 primary health care units from different parts of the state. a direct association was found between the practical implementation of these steps and prevalence of exclusive breastfeeding, as well as with mothers' satisfaction. an analysis of meanings ascribed by pregnant women and mothers to the support provided for breastfeeding identified five categories: "no support", "doubtful support", "encouragement", "guidance", and "partnership". the evaluation model allowed staff at the health care units to recognize opportunities for improving the program, in order to reverse the current low prevalence of exclusive breastfeeding.
