Are ABO Blood Groups and Rh Factor Risk Factors for Hypertensive Diseases of Pregnancy?

Abstract

Introduction:The primary aim of our study was to investigate the relationship between hypertensive diseases of pregnancy (HDP) and blood groups. Our secondary aim is to determine the risk factors that play a role in the development of HDP.Methods:Pregnant women aged 15-49 years were included in this cross-sectional, observational, and prospective study. Pregnant women were divided into two groups. Group 1 (n=266) included patients admitted to the intensive care unit due to HDP. Group 2 (n=402) included normotensive patients without any complications during pregnancy. The groups were compared in terms of age, blood groups, Rh factor, gravida, parity, gestational week, and primiparity-multiparity.Results:There was no statistically significant difference between the groups in terms of ABO blood group and Rh factor. The mean age, gravida, and parity were significantly higher in Group 1 than in Group 2 (p=0.028; 0.001; 0.004, respectively), while mean gestational age was lower than Group 2 (p<0.001). We also found that high gravida, low gestational age, presence of comorbidity, and primiparity were risk factors for HDP.Conclusion:We did not find any relationship between HDP and blood groups. We found that high gravida, low gestational age, presence of comorbidity, and primiparity are risk factors for HDP.
