Factors Associated with Pregnancy Outcomes in Hypertensive Pregnant Women in a District Hospital in Benin

Abstract

Introduction: Hypertension is a major cause of maternal and perinatal morbidity and mortality. This study aims at exploring the outcomes of pregnancy and associated factors in hypertensive pregnant women in Comè district hospital from 2014 to 2016. Methods: This is a retrospective, analytical study carried out in June 2016, involving a total of 345 hypertensive patients. Socio-de- mographic and medical features, including pregnancy and foetal outcomes parameters, were recorded in the case files. Top-down stepwise logistic regression was performed at the 5% threshold. Results: The frequency of hypertensive disorders during pregnancy was estimated at 7.32% and unfavourable outcomes at 35.65%. The adverse maternal outcomes recorded were postpartum death and haemorrhage whereas adverse foetal issues were prematurity, low birth weight, low Apgar scores, stillbirth and death. Factors statistically associated with pregnancy outcome were paucigravida (OR = 2.01 ([1.05 - 3.88]), p = 0.035), history of stillbirth (OR = 4.75 ([1.01 - 22.1]), p = 0.048) and anticonvulsant therapy (OR = 0.32 ([0.19 - 0.54]), p < 0.001). Conclusion: Adequate monitoring via Antenatal Care (ANC) check-ups, timely recourse to care and an effective communication strategy should reduce hypertensive disorders incidence and adverse outcomes in pregnant women.
