Results: The incidence of severe pre-eclampsia was 0.96 per 100 deliveries.  Thei risk factors were primigravida status (adjusted OR:2.4,95%CI: 1.3-4.3); base history of pre-eclampsia (adjusted OR:0,95%CI: 2.7-18.8);  gestational diabetes (adjusted OR:4.6,95%CI: 1.3-16.6); and body mass index of more than 20 kg/m2 prior to the pregancy (adjusted OR:3.3,05%CI: 1.3-8.2). The most common mode of delivery was cesarean section, while normal vaginal birth was the most common mode of delivery in the case and control groups were 2599.7 grams (SD. = 699.4) and 3095.7 grams (SD. = 420.7), respectively.  The percentrage of infacnts with a low birth weight (less than 2500 grams) in the pre-eclampsia group was 40.6% compared with 5.9% in the control group.  Severe birth asphyxia occurred in 9.9 % of the pre-eclampsia group compared with 1.8% in the control group.
