ObjectiveCurrently, there is controversy regarding the diagnosis of gestational diabetes mellitus (GDM) as per the newer International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. We studied the prevalence and associations of GDM in North Indians, diagnosed by the IADPSG criteria.Patients And MethodsWe conducted a cross-sectional study on 332 pregnant women, predominantly belonging to lower and middle socioeconomic strata. The women were screened for GDM between 24 weeks and 28 weeks of gestation by 75g oral glucose tolerance test (OGTT) and GDM diagnosed by the IADPSG criteria.ResultsThe prevalence of GDM was 41.9% [95% Confidence interval (CI) 36.6-47.2%]. Amongst the women diagnosed to have GDM, 91.4% had abnormal fasting plasma glucose (FPG), while 1-h and 2-h post-glucose (PG) levels were abnormal in 18.7% and 17.3% of women, respectively. No maternal factors were significantly associated with GDM. Birth weight of the neonates was similar in women with GDM as compared to those with normal glucose tolerance. In the entire group, fasting glucose levels were associated with the weight of the patient while 1-h PG levels were associated with weight, height, socioeconomic score, and parity.ConclusionsThere is a very high prevalence rate of GDM using the IADPSG criteria in North Indian women of low and middle socioeconomic strata. Further studies are needed to assess the utility of applying these criteria in settings with limited resources.
