Résumé
Background: Vitamin D has an increasingly recognised repertoire of non-classical actions, such as promoting insulin action and secretion, immune modulation and lung development. It therefore has the potential to influence many factors in the developing fetus. Several studies reported the relationship between maternal vitamin D deficiency and adverse maternal and fetal outcomes including gestational diabetes, preeclampsia, preterm labour, low birth weight and increased rate of caesarean section. The present study was undertaken to study the prevalence of vitamin D deficiency in antenatal women of Shimla, India.Methods: The study was conducted in the department of Obstetrics and Gynaecology, Kamla Nehru Hospital, Shimla, India over a period of 12 months. Six hundred women were included in the study.Results: Out of 600 subjects, 568 (94.67%) subjects had vitamin D deficiency and only 32 (5.33%) subjects had sufficient vitamin D levels. Vitamin D deficiency was more common in the vegetarians, dark skinned subjects and in those who were taking vitamin D supplements.Conclusions: It is concluded from this study that there is high prevalence of vitamin D deficiency in antenatal women of Shimla, India.
