Abstract

Nutrition campaigns in Primary Health Care (PHC) play an important role in health promotion and the prevention and treatment of injuries.The scope of this paper is to chart and evaluate the scientific output of nutrition in Brazilian PHC.A search and review of the literature and papers was conducted on the PubMed and Lilacs databases, using key words related to PHC and nutrition.The studies were restricted to Brazil with the professionals or population assisted by PHC in the Brazilian Unified Health System and published prior to March 2011.The references in the selected articles were also consulted in order to identify additional studies.From the total of papers located, 68 were eligible and a further 49 were identified in the references lists, such that a total of 117 papers were analyzed.The studies reviewed were mostly original articles, using quantitative methodology, carried out by São Paulo University in that state and published from 2002 to 2011.The main issues were diagnosis seeking the evaluation of nutritional status involving children.The output in this field is growing, although there is a need to redirect the scope of future studies to a focus on intervention models and program evaluation.
