BackgroundPreeclampsia is a multisystem disorder that affects pregnant women. Preeclampsia and its complications are the leading causes of maternal and perinatal morbidity and mortality in developing countries. Studies conducted in Ethiopia have primarily concentrated on preeclampsia’s trends and prevalence rather than its obstetrical and perinatal consequences. Thus, this study aimed to determine the risk of adverse obstetric and perinatal outcomes among women with preeclampsia at Woldia Comprehensive Specialized Hospital, Northeast Ethiopia.MethodsA retrospective cohort study was conducted among 140 preeclamptic women and 280 normotensive women who gave birth at Woldia Comprehensive Specialized Hospital between 30 December 2020 and 29 December 2022. Maternal records were retrieved using data-extraction tools. The data were entered into EpiData version 4.6.0.6 and analyzed using SPSS version 26. Binary and multivariable logistic regression models were used to test the associations between independent and outcome variables. The adjusted odds ratio (OR) with a 95% confidence interval (CI) and p-values <0.05 were used to measure the strength of the association and declare the level of statistical significance.ResultsThe odds of at least one adverse obstetric outcome among preeclamptic women were 2.25 times higher than those among normotensive women [AOR: 2.25, 95% CI: (1.06, 4.77)]. In addition, babies born to preeclamptic women were at a higher risk of perinatal death [AOR: 2.90, 95% CI: (1.10, 8.17)], low birth weight [AOR: 3.11, 95% CI: (1.43, 6.7)], birth asphyxia [AOR: 2.53, 95% CI: (1.15, 5.5)], and preterm birth [AOR: 2.21, 95% CI: (1.02, 4.8)] than babies born to normotensive women.ConclusionMore adverse obstetric and perinatal outcomes were observed in women with preeclampsia than those in normotensive women. This study highlights the significantly elevated level of at least one adverse obstetric outcome associated with preeclampsia, low hemoglobin level, and rural residents. Moreover, perinatal death, low birth weight, asphyxia, and preterm birth were significantly associated with preeclampsia.
