The Brazilian Journal of Epidemiology: 18 years of contributing to knowledge dissemination.

The Revista Brasileira de Epidemiologia (RBE - Brazilian Journal of Epidemiology) is completing 18 years as a vehicle for the dissemination of knowledge in the area of health. This knowledge relates to theoretical perspectives, the analysis of the reality of existing health conditions, as well as practices within health services. Fitting within all the disciplines of the field of public health, the origins of this journal, and the concepts that it covers, reflect movements within the health sector and also shadow the areas of operation proposed in the "Master Plans for the Development of Epidemiology in Brazil". Over time, there has been increasing demand for the publication of articles within the journal, a fact that has favored its growing impact factor. The RBE adopted an editorial policy designed to disseminate its production in a bilingual form in order to attain greater international visibility and to meet the needs of both researchers and professionals in the field. Like all Brazilian scientific journals, it has suffered from the absence of national scien-tific and technological policies designed to provide more effective assistive in ensuring its sustainability. Looking towards the future, it is hoped that the RBE will achieve even greater impact within academia, in relation to health service professionals, and, not least, that it will achieve a high impact within society at large.
