Maternal ABO Blood Group and the Risk of Preeclampsia and Pregnancy Outcomes in a Nigerian Tertiary Care Hospital

Abstract

BACKGROUND

Preeclampsia is a multisystemic disorder that contributes significantly to maternal morbidity and mortality including adverse pregnancy outcomes. Though the aetiology is unknown, various risk factors including the ABO blood group have been linked with its occurrence. However, results from studies that assess the association between the ABO blood group and the risk of preeclampsia have been inconsistent. This study aimed to determine the association between maternal ABO blood group and the risk of preeclampsia as well as their pregnancy outcomes.
