Measurement of serum vitamin D levels among the pregnant women. International Journal of Reproduction, Contraception, Obstetrics and Gynecology. 2025 Jul; 14(7): 2118-21232320-17702320-1789https://imsear.searo.who.int/handle/123456789/254071Background: Vitamin D deficiency during pregnancy has been implicated in adverse maternal and neonatal outcomes, including preterm labor. However, study on serum vitamin D status among pregnant women remains limited in the local context. This study aimed to assess the serum vitamin D levels among pregnant women presenting in labor and to explore associations with sociodemographic, behavioral, and obstetric factors. Methods: A descriptive type of cross-sectional study was conducted at the Department of Obstetrics and Gynaecology, Bangladesh Medical University (BMU), Dhaka, from July 2023 to June 2024. A total of 64 pregnant women aged 18-40 years in labor were enrolled, Data were collected using a semi-structured questionnaire. Serum 25(OH) vitamin D levels were measured using the Atellica IM assay. Statistical analysis was performed using SPSS version 26 with significance set at p?0.05. Results: The mean age of participants was 34.86±9.64 years. Most women were housewives (40.6%) and had completed primary, secondary, or higher secondary education (each 28.1%). Approximately 65.6% were primiparous, 45.3% were at 37-38 weeks of gestation, and 25.0% reported pregnancy complications. While 71.9% received vitamin D supplements, 34.4% had low intake of dairy/fish, and 89.1% had ?30 minutes of daily sun exposure. The BMI assessment showed 29.7% were overweight and 20.3% obese. Vitamin D insufficiency was observed in 90.6% of participants. Significant associations were found between serum vitamin D levels and parity (p =0.000) as well as gestational age (p =0.000). Conclusions: Vitamin D insufficiency is highly prevalent among pregnant women in labor, particularly in primiparas and those with preterm labor. Findings highlight the need for targeted nutritional interventions and routine vitamin D screening during antenatal care.Fetal outcomesGestational complicationsVitamin D statusSocio-demographic factorsMaternal healthPregnancyJournal ArticleIndiaDepartment of Obstetrics and Gynecology, Bangladesh Medical University, Dhaka, BangladeshDepartment of Obstetrics and Gynecology, Bangladesh Medical University, Dhaka, BangladeshDepartment of Obstetrics and Gynecology, Bangladesh Medical University, Dhaka, BangladeshDepartment of Obstetrics and Gynecology, Aliahat Hospital, Bogra, BangladeshDepartment of Obstetrics and Gynecology, Aliahat Hospital, Bogra, BangladeshDepartment of Obstetrics and Gynecology, Aliahat Hospital, Bogra, BangladeshDepartment of Obstetrics and Gynecology, Aliahat Hospital, Bogra, BangladeshDepartment of Obstetrics and Gynecology, Aliahat Hospital, Bogra, Bangladesh
