Comparison of Vitamin D Levels among Women with Eclampsia Versus Healthy Pregnant Women

Objective: To evaluate and compare serum vitamin D levels between eclamptic and normotensive pregnant women. Methods: This case–control study was carried out in the Department of Obstetrics and Gynecology, Liaquat University of Medical and Health Sciences Jamshoro, Pakistan, from May to August 2025. A total of 120 pregnant women were enrolled, including 60 with eclampsia and 60 normotensive controls. Women aged 20–40 years with singleton pregnancies beyond 20 weeks were included. Demographic, clinical, and anthropometric data were collected. Serum 25-hydroxyvitamin D [25(OH)D] levels were measured using chemiluminescent immunoassay and categorized as deficient (30 ng/mL). Results: The median age of participants was 28.4 years (26.4–31.3). Women with eclampsia had significantly higher parity, weight, body mass index, and blood pressure readings compared with normotensive controls (all p-values
