Abstract

Objective

To find out the effect of increasing body mass index (BMI) on pregnancy outcomes in nulliparous women delivering singleton babies.

Method

This was a hospital-based observation study, based on 300 nulliparous women delivering singleton babies in June 2009—Sept. 2010. Women were categorized into three groups. Underweight (BMI < 20 kg/m2), normal (BMI 20–24.9 kg/m2), overweight (BMI 25–29.9 kg/m2), and obese (BMI > 30 kg/m2) obstetric and perinatal outcomes were compared by univariate and multivariate analysis.

Results

Maximum patients who underwent LSCS were having BMI > 30 kg/m2 [OR 9.558 (95 % CI 5.82–17.27)]. As compared to women of normal BMI (20–24.9 kg/m2), morbidly obese women faced the higher risk of PIH [OR 8.045 (95 % CI 3.875–16.781)]. Obese women were more likely to have post partum hemorrhage [OR 5.11 (95 % CI 1.76–14.79)] compared with women of normal BMI. Birth weight <2,500 g was more common in women with BMI < 25 kg/m2 (21.21 %), while highest incidence of birth weight >4,000 g (14.29 %) is seen in women of the obese group.

Conclusions

Increasing BMI is associated with increased incidence of cesarean delivery, PIH, post partum hemorrhage, and macrosomic babies.
