Correlation of Vitamin D levels with feto-maternal outcome

摘要

Background: Vitamin D deficiency in adult females may increase risk of pre-eclampsia, gestational diabetes, bacterial vaginosis. Various malpresentation, cephalo-pelvic disproportion and difficult deliveries increases the risk of caesarean section. It may also increase the risk of fetal hypovitaminosis D, neonatal rickets and tetany, lower respiratory tract infections, low birth weight, the largest cause of infant mortality in India. This study was under taken to study the impact of vitamin D deficiency on feto-maternal outcome. Methods: The study was conducted in the Department of Obstetrics and Gynaecology, Himalayan Institute of Medical Sciences (HIMS), Swami Ram Nagar, Dehradun, over a period of 12 months. Sample size was 100 pregnant females attending antenatal clinic. Results: Out of 100 subjects, pre-eclampsia was seen in 15, among which 5 (23.80%) had deficient, 9 (13.04%) had insufficient and 1 (10%) had sufficient vitamin D levels. Eclampsia was seen in 3 subjects, out of which 1 (4.76%) had deficient, 2 (2.89%) had insufficient vitamin D status. IUGR was seen in 8 subjects, out of which 4 (19.04%) had deficient vitamin D levels, 4 (5.79%) had insufficient vitamin D status. Neither of the two had sufficient vitamin D status. Deficient vitamin D status with birth weight ≤2.5 kg was seen in 9 (42.85%) subjects and 12 (57.14%) subjects with 2.5 kg Insufficient Vitamin D status was seen in 22 (31.88%) subjects with birth weight ≤2.5 kg and 48 (69.56%) with birth weight 2.5 kg. Conclusions: Prevalence of vitamin D deficiency and insufficiency was noted in this region and its association with pre-eclampsia (23.80%, 13.04% and 10% in deficient, insufficient and sufficient group respectively) was seen. Higher incidence of LSCS was also present among the deficient and the insufficient group.
