Aims and Objectives: This study evaluates the risk factors that influence preeclampsia in Semarang Indonesia Methods: The research was a case-control study involving 106 pregnancies with preeclampsia and 104 normal pregnancies without preeclampsia as controls who gave birth at KRMT Wongsonegoro Hospital Semarang City, Indonesia for the period January 2018 and December 2018. Data were taken from medical records, information about maternal characteristics, antenatal examination and delivery methods, and perinatal outcomes. Statistical analysis: The Mann-Whitney test was performed for numerical data and the continuity correction test for categorical data with a value of 0.05 to determine the differences in characteristics between the preeclampsia and control groups. To determine the relationship between preeclampsia and various risk factors, using Multinominal Logistic regression analysis with SPSS for Windows, version 22. Results: the group of women without preeclampsia had a higher mean age than women with preeclampsia (p < 0.001). The percentage of primiparas in preeclampsia women is higher than in non-preeclampsia pregnancies (p = 0.002). Preeclampsia can be caused by several variables, including maternal age (OR 0.3; 95 percent CI 0.13-3.46), nullipara (OR 1.75; 95 percent CI 1.75-11.6), and a BMI of 25-29.9 kg/m2 (OR 0.4; 95 percent CI 0.21-0.85). Conclusion: Preeclampsia can arise due to several risk factors, including maternal age, nulliparity, and obesity.
