O Blood Group as Risk Factor for Preeclampsia among Sudanese Women

AIM: To investigate blood groups and the other possible risk factors for preeclampsia among Sudanese women. MATERIAL AND METHODS: A case – control study was conducted at Saad Abualila Hospital, Khartoum, Sudan during the period of July 2013 through December 2014. The cases were women with preeclampsia and healthy pregnant women were the controls. RESULTS: Two hundred eighty pregnant women were enrolled (140 in each arm of the study). Around one-quarter of all women (280) were primiparae (74.0, 26.4%), the majority were housewives (201, 71.7%). Seventy-nine (28.2%) were illiterate or had no informal education. Around half of the women (130, 46.4%) had O blood group. Binary logistic regression showed association between preeclampsia and lack of antenatal care (OR = 2.75, 95% CI = 1.172–6.494, P = 0.020) as well as O blood group (OR = 1.78, 95% CI = 1.088–2.934, P=0.022). CONCLUSION: The current study showed that women with blood group O were at higher risk of preeclampsia.
