Abstract
Objective: To evaluate the knowledge production about the prevalence of diseases screened by newborn screening in Brazil from 2008 to 2018. Methods: This is an integrative review in which data collection was performed on online platforms Scielo, LILACS and BVS. Data were analyzed through tables and discussed with current and pertinent literature. Results: During the analyzed period 17 studies were found. The greatest knowledge production about prevalence of screened diseases was hemoglobinopathies (twelve studies including those dealing with sickle cell disease only), followed by phenylketonuria (eight studies) and congenital hypothyroidism (seven studies). The least knowledge production was about biotinidase deficiency (one study). Final considerations: It is evident that research about prevalence of diseases screened by newborn screening in Brazil need to be expanded, for the reason that there is discrepancy of scientific production throughout national territory. Therefore, it would be possible to plan better public policies to serve the target population.
