Abstract

This study aims to find the possible correlation of vitamin D with the onset of gestational diabetes mellitus (GDM) and its effect on fetal growth. A case-control study was conducted recruiting pregnant women in their second trimester. All subjects were classified as per the guidelines of the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criterion. Fetal growth scans were recorded at 28th week of gestation. Venous blood was collected and serum levels of 25-(OH) D, Calcium, TNF alpha were measured. Vitamin D concentration in cases was lower (2.40 ± 1.10 ng/ml) as compared to controls (5.50 ± 1.74 ng/ml), while serum calcium levels of both groups were under normal range. TNF alpha level in cases was higher as compared to controls (p < 0.001). On ultrasound scan, 47% of the babies of GDM mothers were small for gestational age. No difference was observed in terms of femur length and fetal weight in both groups (p > 0.05). Weak negative correlation of vitamin D with insulin resistance (r = −0.304; p = 0.004), positive correlation with fetal growth (r = 0.303; p = 0.043) and a strong negative correlation with TNF alpha levels (r = −0.703; p = 0.023) were observed. Low vitamin D levels may be associated with the onset of gestational diabetes and affect fetal growth and development. Hence, antenatal screening and timely intervention is recommended.
