Background and Objective: Proper antenatal care is one of the important ways in reducing maternal and child morbidity and mortality. Pregnancy comes with some cost, however, for a pregnant woman needs also to be a responsible woman so as to best support the health of her future child. This present study was conducted to assess the risk factor associated with gestational diabetes mellitus among pregnant women attending antenatal clinic. Methodology: This one year cross sectional study was done in three UHCs Ram Nagar, Ashok Nagar and Rukmini Nagar which are urban field practice area of Jawaharlal Nehru Medical College, Belagavi. Data was collected from 360 pregnant women attending the antenatal clinic of three UHCs. Information on socio demographic details was obtained. Information on socio demographic details and risk factors associated with GDM was obtained. Woman was given a standardized 75gm of oral glucose load, irrespective of whether she was in fasting or non fasting state and without regard to time of last meal, and plasma glucose was estimated at 2 hours by using Diabetes in Pregnancy Study group India (DIPSI criteria) and all women with a plasma glucose of ≥ 140 mg/dl were diagnosed to have GDM. Results: The trends association was observed statistically significant in age associated with GDM (p=0.012) as the age was increased the prevalence of GDM was increased. The prevalence of GDM increased with multigravida and this shows that the severity of gestational diabetes mellitus increases with gravidity which is found to be statistically significant (p=0.002) Conclusion In this study there is a greater prevalence of GDM in women with increasing age, higher parity. There is a need for universal screening to pick up gestational diabetes mellitus to prevent both maternal and fetal morbidity. Based on these results it concluded that, the diagnosis of GDM based on DIPSI method is a convenient, quick and cost effective.
