Niveles de Vitamina D en pacientes obstétricas en el primer trimestre de embarazo

OBJECTIVE: to determine vitamin D levels in obstetric patients during the first trimester of pregnancy who attended a private clinic in the department of Jalapa between August and September 2025. METHOD: a descriptive, cross-sectional study was conducted in a sample of 40 obstetric patients in the first trimester of pregnancy who had serum vitamin D measurements. Data were obtained from medical records and included sociodemographic variables, obstetric history, classification of vitamin D levels, and the presence of clinical and ultrasonographic complications. RESULTS: 65% of the patients presented insufficient or deficient vitamin D levels, while 35% had sufficient levels. The most frequent age group was 26–30 years, with a predominance of urban origin and university-level education. Regarding obstetric history, second pregnancies, previous cesarean section, and preeclampsia were the most frequent findings. Insufficient vitamin D levels predominated, followed by deficient levels. Among patients with decreased vitamin D levels, urinary tract infection, threatened miscarriage, vaginal bleeding, and miscarriage were the most commonly observed complications. Ultrasonographic evaluation revealed fibroids and mild fetal heart rate abnormalities. CONCLUSION: a considerable proportion of obstetric patients in the first trimester showed decreased vitamin D levels, highlighting the importance of considering early vitamin D assessment as part of prenatal care.
