Abstract
Introduction:
Gestational diabetes mellitus (GDM) is a public health problem that currently affects a large part of the female population and has short- and long-term consequences for the fetus and the mother. It has been reported that GDM affects 1%-14% of all pregnancies, and that its incidence has been steadily rising. In recent years while exploring the etiological factors responsible for the emergence of insulin resistance particularly that of transient nature, vitamin D has emerged as one of the possible factors. Although systematic review and metaanalysis of observational studies show that low blood vitamin D level during pregnancy is associated with 1.8 times higher odds of GDM as compared to those having normal blood vitamin D levels; however, individual observational studies about maternal vitamin D status and risk of GDM are conflicting, The aim of this study is to compare the levels of 25(OH) vitamin D in women with gestational diabetes mellitus and normoglycemic pregnant women to assess the pathogenic role of vitamin D in the causation of GDM.
Materials and methods:
This study was conducted in the Department of Obstetrics and Gynecology, Era's Lucknow Medical College and Hospital (ELMCH), Lucknow from December 2018 to November 2020 The present study was an analytical case-control study, in which a total of 30 pregnant women in 24-28 weeks of gestation diagnosed as GDM using Diabetes in Pregnancy Study Group criteria were enrolled as cases while another 30 pregnant women in same gestational age range with normoglycemic profile were enrolled as controls. The 25(OH)D levels were assessed by the chemiluminecence immunoassay. The statistical analysis was performed using SPSS (Statistical Package for Social Sciences) Version 21.0.
Results:
On multivariate analysis, vegetarian diet and GDM were found to be significantly associated with vitamin D deficiency. The present study endorsed the relationship between vitamin D deficiency and GDM and showed a high prevalence of vitamin D deficiency, and that too at severe level could result in GDM. Appropriate awareness and intervention strategies are warranted on a larger sample.
