HERNANDEZ F, LUIS J. What is the evidence based public health?. Rev. salud pública [online]. 2003, vol.5, n.1, pp.40-45. ISSN 0124-0064.

Evidence based Public Health is the execution and evaluation of the efficiency of interventions, plans, programs, projects and politics in public health through the application of the scientific principles of reasoning, including the systematic use of information and information systems. Evidence based public health involves the use of methodologies similar to those applied in evidence-based clinical medicine, but differs in its contents. In public health two types of evidence are described. The type I evidence in which a strong relation exists between the preventable risk and disease, and type II evidence in which there exists a relative effectivity of the public health interventions. In evidence based Public Health research designs more appropriate for the social sciences are used, as the observational and quasi-experimental studies. Likewise the decisions are more of interdisciplinary teams
