Abstract

Gestational diabetes mellitus (GDM) is an emerging public health concern in India, which has detrimental effects on both the mother and the baby. The data on prevalence of GDM was unavailable at secondary urban health facilities, from where a majority of pregnant women seek antenatal services, and the following study identifies this burden. A cross-sectional study was conducted from May 2019 to June 2020 among pregnant women attending the antenatal outpatient department (OPD) at secondary level health facilities in urban Lucknow. A semi-structured interview schedule was administered to the study subjects for collecting the relevant information and 75 g of oral glucose tolerance test was performed irrespective of the meal.

The overall prevalence of GDM and GGI in the study was 11.6% and 16.8%, respectively. Three-fourth of the women (22/29) were diagnosed with GDM in the second trimester of pregnancy. The prevalence of GDM (16.7%) was significantly higher in pregnant women aged more than 25 years and in those who were overweight. Mean birth weight (3.2 ± 8.1 kg) of the babies was significantly higher in the women with GDM. Among the fetal complications was respiratory distress observed among 28 pregnant women and 31% of them had GDM and this was statistically significant. The prevalence of GGI and GDM was found 16.8% and 11.6%, respectively. Gestational age, pre-pregnancy weight, pre-pregnancy BMI, weight gain during the pregnancy, family history of diabetes.
