The cases were pregnant women diagnosed with preeclampsia, while the controls were pregnant women without preeclampsia. Participants’ sociodemographic and obstetrical data were assessed via a questionnaire. Multivariate binary analyses were also performed.Results: Women with preeclampsia were less likely to have used periconceptional folic acid supplementation (12 [9.4%]26 vs [20.5%], p = 0.016). The univariate binary analysis showed that maternal age, gravidity, overweight/obesity, and periconceptional folic acid supplementation were significantly associated with preeclampsia. However, residence, internal displacement, couples’ education, maternal occupation, maternal blood group, antenatal care, anemia, and number of fetuses in the current pregnancy were not associated with preeclampsia. The multivariate binary analysis showed that primigravida (adjusted odds ratio, AOR = 6.20, 95% confidence interval, CI 3.16– 12.14), not taking periconceptional folic acid supplementation (AOR = 2.24, 95% CI 1.02– 4.96), and being anemic (AOR = 1.94, 95% CI 1.10– 3.40) were associated with an increased risk of preeclampsia. However, maternal age and being overweight or obese were confounding factors.Conclusion: This ... |
