Hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM) are leading causes of maternal and fetal-neonatal morbidity and mortality. Their effects are believed to be associated with umbilical cord macroscopic changes. This study aimed to examine the association of umbilical cord macroscopic changes and newborn outcomes in high-risk pregnancies. A descriptive cross-sectional study was conducted in a public maternity hospital affiliated to the Brazilian National Health System (SUS) in the city of Goiânia, central-west Brazil, between January and December 2012. Medical information on high- (HDP and GDM) and normal-risk (control) pregnancy women and their newborns was collected in the postpartum period as well as information on the macroscopic characteristics of the umbilical cord of these infants. A total of 265 umbilical cords were examined. Of these, 126 were from the high-risk pregnancy group (64 of children of mothers with HDP and 62 of those of mothers with GDM) and 139 from the control group (73 HDP and 66 GDM controls). The most common umbilical cord macroscopic changes included true knots and non-central cord insertion in newborns of mothers with HDP and cord less than 35 cm long, true knots, and non-central cord insertion in those of mothers with GDM. Maternal age ≥36 years was significantly associated with single umbilical artery (SUA) (p = 0.03) in the control group. No statistically significant association was found between umbilical cord macroscopic changes and clinical characteristics of newborns of high-risk pregnancy women.
