Factors causing preeclampsia from the mother come from internal and external factors. This study aims to describe age, BMI, and vitamin D levels in normal pregnant women and with preeclampsia in Kupang City. Materials and Methods: This type of research is descriptive cross-sectional, in normal pregnant women and preeclampsia, with a sample of 30 people, obtained using the Quota Sampling technique. Results: 30 pregnant women participated in this study. The results showed that most of the mothers with normal pregnancies (66.7%) and preeclampsia (60%) were of reproductive age, namely 20-35 years. Most pregnant women (60%) have a BMI in the overweight category. Most of the normal pregnant women (73.3%) had normal serum vitamin D levels as many as 11 respondents (73.3%), while most of the pregnant women with preeclampsia (46.7) were deficient. Discussion: Maternal age and BMI can increase the risk of developing preeclampsia. Serum vitamin D levels have a role in the incidence of preeclampsia in pregnant women.
