Regional prevalence of gestational diabetes mellitus in North India

Background and Objective: Incidence of gestational diabetes mellitus (GDM) varies globally from 2% to 14%. These cases in India are also increasing and emerging as a major public health problem. The prevalence of GDM among urban population of India has been reported as 16% and 17.8%, respectively. We conducted this study at three different regions of North India to estimate the prevalence of GDM. Materials and Methods: This pilot prospective cross-sectional study was conducted at three centres of North India with a base at Max Super Speciality Hospital, Saket, New Delhi, over a period of 10 months (December 2015–October 2016). Pregnant females attending gynaecology clinic at these centres were screened and enrolled as per the study inclusion criteria, after taking informed consent. Medical records were reviewed for recent haemoglobin levels, fasting blood sugar levels and other clinical parameters. Results: A total of 230 participants were enrolled in this study with 65 from Muzaffarpur, 65 from Bhilai and remaining 100 from Delhi, which include a mixed population. The overall prevalence of GDM was observed as 10%, with a regional prevalence of 10.77% at Bhilai, lower prevalence at Muzaffarpur (3.07%) and 14% in Delhi with a mixed population. A significant difference (P < 0.01) was observed in the mean age and body mass index of participants at Bhilai, Muzaffarpur and Delhi. Conclusion: Although there was a variable sample size at these three centres, we could conclude from this pilot study that there is a high prevalence of GDM at Bhilai district while very low prevalence at Muzaffarpur and Bihar. Large-scale studies are required to be done to estimate the prevalence in these regions, which would ultimately create awareness among clinicians to screen all females for GDM
