Determinants of Preeclampsia Among Pregnant Women in Chiro Referral Hospital, Oromia Regional State, Ethiopia: Unmatched Case-Control Study.

Abstract

BackgroundPreeclampsia causes striking maternal, fetal, and neonatal mortality and morbidity both in developed and developing countries. However, evidence of risk factors of preeclampsia is limited in the study area.ObjectiveTo identify determinants of preeclampsia among pregnant women attending antenatal care services in Ciro Referral Hospital, Ethiopia, 2020.MethodsA facility-based unmatched case–control study was conducted from July 1 to July 30, 2020, in Chiro Referral Hospital on a sample size of 306 (ie, 76 cases and 230 controls; with a 1:3 ratio). Data were coded and entered into Epi Info version 7 and then exported to SPSS version 21 for analysis. The odds ratio was calculated with 95% confidence intervals to show the strength of association and p-value<0.05 was used to declare statistical significance.ResultsA total of 302 (75 cases and 227 controls) pregnant mothers were interviewed with a response rate of 98.7%. Being in the age group ≥35 years (AOR=4.00; 95% CI=1.25–12.80), rural residence (AOR=3.30; 95% CI=1.50–7.26), having a family history of hypertension (AOR=3.25; 95% CI=1.36–7.73), and being primigravida (AOR=3.71; 95% CI=1.49–9.22) were identified as risk factors for preeclampsia. However, consuming fruits more than 2–4 times per a week in their diet (AOR=0.38; 95% CI=0.15–0.98) was a protective predictor of preeclampsia.ConclusionMaternal age, residence, family history of hypertension, gravida, and frequency of fruit consumption were identified determinants of preeclampsia. Thus, healthcare providers should give emphasis for pregnant mothers in the older age category, primigravida, those who have a history of a family with hypertension, and those from a rural residence to diagnose the diseases as early as possible. Additionally, advising pregnant mothers attending antenatal care to consume fruits as early as possible in their daily diet reduces the risk of preeclampsia.
