The Relation between ABO Blood Group and Pre-eclampsia in Primipara Women

Background and Aims: Preeclampsia is one of the causes of maternal mortality whose leading cause is still unknown. This study was conducted to investigate the relation between blood group and pre-eclampsia in primipara women. Materials and Methods: This case-control study was performed on 100 pirmipara women in Gonabad city. The samples were assigned, by census, into two groups of case (with pre-eclampsia) and control (without pre-eclampsia). The data were analyzed using descriptive statistics and Chi-square through SPSS software Ver.16. Results and Conclusions: The incidence of preeclampsia in the blood group of A, B, AB, and O were 36%, 34%, 22%, and 8%, respectively. Also, there was a significant difference between blood group O and blood group non-O to preeclampsia (p<0.001). The findings showed that the women with A and B blood types require special care with an emphasis on controlling and preventing the factors which cause hypertension/preeclampsia during pregnancy.
