Abstract

Objective: Maternal BMI is a good indicator of maternal nutritional status. Being
overweight, obese or underweight carry adverse effects on the mother as well as the fetus.
Our objective was to classify pregnant women in early pregnancy according to WHO
International and Asian BMI cut-offs and compare their pregnancy outcomes.
Methods: It was a prospective observational study over a period of one year. Women who
had antenatal visit within 14 weeks of gestation and delivered in our hospital were included.
A total of 209 women were available for analysis.
Results: Mean age of the cohort was 28.1±3.9 years. As per Asian BMI cut-offs, 34.9%,
17.2%, 47.8% women had BMI in normal, overweight, and obese range respectively.
However, on WHO BMI cut-offs, 52.2%, 37.3% and 10.5% of women had normal,
overweight, and obese range respectively. Hypertensive disorders of pregnancy and
gestational diabetes was the commonest antenatal complication. Caesarean delivery
had significant association with overweight and obese women. Asian BMI cut-offs had
significant predictability for antenatal complications. Sensitivity, specificity, and positive
predictive value of Asian BMI were 69%, 68.2% and 94.9% when compared with 50.8%,
77.3% and 92% of WHO BMI.
Conclusion: Asian BMI has high sensitivity in predicting adverse pregnancy outcomes.
