The incidence of preeclampsia (PE) is associated with numerous risk factors that are classified as high and moderate risk factors. In this context, we carried out this study to determine the potential risks of PE and to highlight those associated with the severity of the disease. This is a case-control study of 200 pregnant women, groups of 100 preeclamptic (PG) and 100 non-preeclamptic (NPG) admitted between March 2022 and January 2023 at the Maternity Ward of Sidi Bel Abbes (Algeria). Data were analyzed using SPSS for Windows version 20. Frequencies and percentages were calculated for categorical variables; the Chi-square test was performed to compare between the two groups; the risk factors and the odds ratio were identified using binary regression. The current study showed that the development of PE was associated with several risk factors, in particular renal disease, BMI ≥ 35 and represented potential risk factors for the development of PE with an a OR of (21.65, 95% CI; 2.56-182.75) and (18.47, 95% CI; 4.37-78.01), respectively. Furthermore, a history of PE and gestational hypertension were potential risk factors and contributed to the development of the severe form of PE with an aOR of (6.55, 95% CI;2.78-15.43) and (7.32, 95% CI; 1.60-33.35); respectively
