Background: Maternal nutritional status and gestational weight gain (GWG) may be associated with complications of pregnancy and delivery. Objectives: The aim of our study was to compare the proportional weight gain during pregnancy among Asian Indians across different body mass index (BMI) categories and to compare the pregnancy outcomes in each of the different BMI categories. Methods: Follow up study of 83 pregnant women attending antenatal clinics of KGMU, Lucknow, India, was done. Pregnancy outcomes were analysed in relation to initial BMI and proportional weight gain across different BMI categories. Results: There was a decreasing trend in proportional weight gain with increase in nutritional status. Proportional weight gain was maximum in underweight and minimum in obese. Proportion of LSCS deliveries were significantly higher (p<0.001) in overweight (70.0%) and obese (86.0%) females. Similarly, proportion of preterm deliveries were significantly higher (p<0.001) in overweight (70.0%) and obese (97.7%) females. Conclusion: Women who’s initial BMI was towards higher side, gained less weight and were at a high risk of developing adverse pregnancy outcomes. Normal weight women gained more weight and had low risk for caesarean section and preterm deliveries.
