Pre-eclampsia has remained a significant public health threat in both developed and developing countries contributing to maternal and perinatal morbidity and mortality globally (Pregnancy, 2000). Pre-eclampsia affects 5–10% of all pregnancies globally. The prevalence of pre-eclampsia in developing countries reaches up to 16.7%, and it is estimated to account for about 40–60% of maternal deaths in developing countries ( Osungbade and Ige, 2011 ). The World Health Organization (WHO) estimates the incidence of pre-eclampsia to be seven times higher in developing countries (2.8% of live births) than in developed countries (0.4%) ( LILL et al., 2008 ).
