Glycemic control and its associated factors among women with gestational diabetes mellitus in a tertiary care Centre, Puducherry, South India.

Abstract

Background:Worldwide, one in ten pregnancies is related with diabetes; 87.6% of which are gestational diabetes mellitus (GDM). Maternal hyperglycaemia affects the successful progression of pregnancy.Objectives:To determine the proportion and the factors associated with poor glycaemic control among women with gestational diabetes.Methods:This hospital-based cross-sectional study was conducted in a tertiary care hospital, Puducherry, South India from September to October 2019. Pregnant women diagnosed as GDM and on treatment for at least one month were approached consecutively for the study. A fasting blood sugar (FBS) ≥92 mg/dl and postprandial blood sugar (PPBS) 1 hour ≥180 mg/dl or PPBS 2 hour ≥153 mg/dl were considered as poor glycaemic control.Results:A total of 301 women with GDM were included and the mean (SD) age was 27 (5) years. Of total, 29 (10%) reported GDM during their previous pregnancy and 95 (32%) got diagnosed before reaching the tertiary care hospital. Lifestyle modifications (77%) were the most common mode of management for GDM. Of total, 116 (38.5%; 95% CI 33%-44.3%) had poor glycaemic control. Multigravida women (46.9%) and those on pharmacological treatment for GDM had poor glycaemic control.Conclusion:One-third of women with GDM at a tertiary care centre had poor glycaemic control. Therefore, a novel approach to improve awareness about GDM control both among pregnant women and the medical fraternity is needed.
