Maternal obesity and obstetric outcome in pregnant women attending PNS Shifa Karachi

Abstract

Objective: To evaluate the impact of obesity on maternal and neonatal outcome. Study Design: Comparative cross sectional study. Place and Duration of Study: Department of Gynaecology and Obstetrics, Pakistan Naval Ship, Shifa Hospital Karachi, from Nov 2016 to Oct 2017. Methodology: All singleton pregnant women of normal prepregnancy body mass index (BMI) and obese women having ≥30 body mass index, delivering newborn at 28-42 weeks of gestation were included. Comparison of antenatal complications and neonatal outcomes was done among both groups. Results: Obese women significantly developed gestational hypertension (OR=7.4 95% CI, 4.84-11.4), preeclampsia (OR=2.22 95% CI, 1.36-3.6), gestational diabetes mellitus (OR=5.2; 95% CI, 3.57-7.58), labor induction (OR= 2.79 95% CI, 2.03-3.84), failed induction of labor (OR = 5.3 95% CI, 8.05-29.38), cesarean delivery (OR=1.89 95% CI, 1.41-2.5), large for gestational age newborn (OR=3.97 95% CI, 2.87-5.50). But there was no statistically significant difference in small for gestational age newborn (OR=0.91 95% CI, 0.42-1.98), new born with APGAR score ≤7after 5 min after delivery (OR=2.168 95% CI, 0.97-4.82) among obese and normal weight pregnant women. Conclusion: There is increased risk of gestational hypertension, preeclampsia, gestational diabetes, failed induction of labor, dystocia, cesarean delivery and large for gestational age newborns in obese women.
