Introduction: The prevalence of obesity is increasing in women of reproductive age. Maternal obesity is associated with increased morbidity and mortality for both mother and offspring. BMI has been criticized as a limited measure of total obesity. Measurement of waist circumference can be useful in the assessment of abdominal obesity and disease risk. The study is aimed to evaluate the waist circumference as an anthropometric parameter in identifying women at risk of developing obstetric complications. Material and Methods: A prospective study was conducted at a tertiary health care centre on 200 antenatal women of age between 18 to 35 years with singleton pregnancy attending the antenatal clinic before 8 weeks of gestation. Women were divided into two groups. Group I included 100 women with waist circumference < 80 cm and Group II included 100 women with waist circumference ≥ 80 cm. Weight, height and waist circumference were measured and BMI was calculated. All the women were followed throughout their pregnancies as per the routine antenatal follow up. The fetomaternal outcome was recorded and analyzed statistically.
