Background: Obesity in the general population is reflected in maternal obesity, which is becoming a public health concern in both industrialized and developing nations. There are no data on maternal obesity and overweight in our community. Aim: To evaluate relation between maternal obesity and obstetric outcomes. Methods: The study was conducted on 150 pregnant females in Department of Obstetrics and Gynecology at Abu Qir General Hospital and Zagazig University Hospital. Pregnant women were divided into group A (75 patients) included 75 normal pregnant females BMI18 – 25 kg/m2 and group B (75 patients) included 75 patients with obesity BMI > 30 kg/m2. Maternal and neonatal outcomes were measured. Results: Obese women had a significantly higher incidence of gestational hypertension than normal-weight women. FBG is significantly higher in obese women that normal, there was also significant difference between the two groups regarding miscarriage. Neonatal macrosomia and shoulder dystocia were higher in obese patients than normal group. Conclusion: Both overweight and obesity significantly increase the risk of gestational DM, gestational hypertension , NICU admission, macrosomia, and shoulder dystocia.
