BACKGROUND: New-onset postpartum preeclampsia has emerging as a significant public health concern in Ethiopia, with a notable increase in incidence in the study area. While substantial research exists on antepartum preeclampsia, data on the determinants of new-onset postpartum preeclampsia are limited. Therefore, this study aimed to investigate determinants of new-onset postpartum preeclampsia among mothers who gave birth at hospitals in the South Gondar Zone, Northwest Ethiopia.
METHODS: An unmatched case-control study was conducted with 355 postpartum mothers (89 cases and 266 controls). A multistage sampling method was used to select the study participants. Data were collected using structured questionnaires and medical chart reviews, and analyzed using SPSS Version 27. Binary logistic regression (bivariable and multivariable analysis) was used to identify factors associated with new-onset postpartum preeclampsia. Statistical significance was set at p < 0.05, and strength of associations were measured using adjusted odds ratios (AOR) with 95% confidence intervals (CIs).
RESULT: New-onset postpartum preeclampsia was significantly associated with several factors, including advanced maternal age, fewer antenatal care (ANC) visits, contraceptive use, physical inactivity, a history of multiple gestations, and gestational diabetes mellitus. Specifically, maternal age ≥ 40 years (AOR = 11.63, 95% CI: 4.24-31.86), fewer than four ANC visits (AOR = 8.45, 95% CI: 3.96-18.05), contraceptive use (AOR = 4.04, 95% CI: 1.26-13.37), irregular physical activity (AOR = 4.05, 95% CI: 1.32-12.44), physical inactivity (AOR = 8.25, 95% CI: 4.62-19.29), a history of multiple gestations (AOR = 2.66, 95% CI: 1.26-5.60), and gestational diabetes mellitus (AOR = 17.79, 95% CI: 7.72-40.95) were identified as key determinants.
CONCLUSIONS: Advanced maternal age, fewer ANC visits, contraceptive use, physical inactivity, multiple gestations, and gestational diabetes were strongly associated with new-onset postpartum preeclampsia. Increased ANC visits and postpartum monitoring are essential for early detection and management of postpartum preeclampsia. Additionally, promoting physical activity should be incorporated into maternal health strategies to reduce the incidence of new onset postpartum preeclampsia.
