摘要:Introduction: Gestational diabetes mellitus (GDM) has been observed to be associated with increased perinatal morbidity and mortality. GDM is becoming a public health concern globally as well as in India with fast increasing trend. It affects approximately 14% of all pregnancies. Most of the literature available has focused on traditional risk factors while this article has thrown light on modifiable ones. Objective: To study the modifiable risk factors for developing GDM in pregnant women based on physical examination and personal history. Materials and Methods: A hospital based case control study was conducted in Lady Hardinge Medical College and associated hospital with a sample size of 104 (52 cases & 52 controls). Pregnant women with gestational diabetes mellitus as diagnosed by abnormal oral Glucose Tolerance Test (OGTT) were taken as cases and Pregnant women who have completed 24 weeks of gestation and who tested negative on Glucose Challenge test (GCT) were selected as controls.bThe data was compiled and analysed in SPSS version 12. Results: Pre pregnancy BMI >23kg/m² (OR-12.96), Skinfold thickness >13mm (OR-5.30). OCPs use for more than 5 years (OR-4.71), Physical activity sedentary vs moderate (OR=1.40), consumption of food item with high GI (OR=2.86). Conclusions: The information found in the study regarding the risk factors may contribute heavily to the policy makers to develop strategies to combat the problem of GDM in the community
