A pilot study on the usefulness of body mass index and waist hip ratio as a predictive tool for gestational diabetes in Asian Indians.
Gestational diabetes mellitus (GDM) is a common public health issue of pregnancy and women who have had GDM are at high risk for developing of diabetes mellitus Type-2. The aim of this study was to find the association between various clinical and biochemical parameters and GDM. One hundred and six consecutive patients who attended the out patient unit of department of gynecology, Kottayam Medical College, were enrolled in the study and followed up through the whole antenatal, intra-partum and post-partum periods to identify the obstetric outcome. We found that the prevalence of GDM was seven times higher in those with higher waist-hip ratio (WHR > 0.85) compared with those having a lower WHR (p < 0.001).Those with higher WHR gained more weight than other group (10.6 kg vs. 8.1 kg; p < 0.001). Obesity (BMI > or =23) and higher WHR were associated with increased risk of gestational diabetes (BMI > or =23: OR = 7.5, CI 95% = (1.61-34.31), p = 0.013; WHR > 0.85: OR = 12.05, CI 95% = (1.82-77.43), p = 0.007). We found that a WHR of 0.849 has the optimal sensitivity and specificity for the prediction of GDM. A waist circumference of 85.5 cm (with sensitivity of 75%, specificity 81.4%) and a BMI of 24.3 kg/m(2) (sensitivity 75%, specificity 86.5%) had the best predictive value. In conclusion, we found that maternal obesity has a strong correlation with obstetric complications. We found WHR is more important risk determinant for GDM in overweight/obese women than women with normal weight/lean.
