Abstract
ABSTRACT Purpose: to investigate the results of the Neonatal Hearing Screening (NHS) in neonates whose mothers presented hypertension and/or diabetes mellitus in their pregnancy. Methods: a systematic review of the literature, without restriction of year and language, guided by the PRISMA protocol, that was carried out through a search in the MEDLINE (PUBMED), LILACS (BVS), SCOPUS, WEB OF SCIENCE and EMBASE databases, using neonatal screening AND hearing AND (hypertension OR diabetes mellitus) as descriptors. Studies that were duplicated or were unavailable were excluded. Results: 64 records were found, 5 being included for analysis. These articles had been published in the last 13 years, originated from different countries, and using a retrospective (cross-sectional, n=1, case-control, n=1) or prospective design (cross-sectional, n=1, case-control, n=1; cohort, n=1). The findings of the articles demonstrated differences regarding the presence of changes in the NHS outcomes of newborns whose mothers presented hypertension and/or diabetes during pregnancy. Conclusion: since the review showed contradictory results regarding changes in the NHS outcomes in the presence of mothers’ hypertension and/or diabetes during pregnancy, prospective cohort studies are needed, in different contexts, in order to isolate confounding factors for hearing loss and minimize measurement bias and selection.

Pregnancy is a physiological phenomenon which involves many psychosocial changes and that must be considered by the pregnant women and healthcare teams as part of a healthy life experience[1]
The current study aimed to investigate of the results of Neonatal Hearing Screening (NHS) of newborns whose mothers displayed hypertension and/or diabetes mellitus during pregnancy
Brainstem Auditory Evoked Potential (BAEP): (p= 0.573) This study suggests that preeclampsia might have some temporary effect over the hearing of newborns
Summary
Pregnancy is a physiological phenomenon which involves many psychosocial changes and that must be considered by the pregnant women and healthcare teams as part of a healthy life experience[1]. In the presence of medical conditions that might affect the health and/or life of the mother or the fetus (or even both), pregnancy begins to be considered a “high risk pregnancy”. This term is used to indicate the presence of hazardous situations, that might occur during pregnancy, birth or post-birth, and that end up representing a bigger probability of unfavorable development of those events[1,2,3]. The gestational diabetes and hypertension diagnoses are the ones most frequently associated with high risk pregnancy, providing additional challenges for the experiences of gestation, birth and puerperium[1]. The hypertensive disturbs are displayed from 5 to 10% of pregnancies, while preeclampsia afflicts about 3%5
