Abstract
Background: To estimate the effect of the maternal BMI on the progress of labour, mode of delivery and feto-maternal complications in primigravida.
Methods: It is a cross-sectional descriptive study including 295 women, primiravida, with singleton pregnancy, cephalic presentation attending labour ward in El-Hussien and Sayed Galal Hospitals from March 2016 to November 2016 in the latent phase of labour. Patients were divided into 3 groups, group (A): Pregnant women who are normal weight BMI between 18.5-24.9kg/m2, group (B): Pregnant women who are over wight BMI between 25-29.9kg/m2, group (C): Preg-nant women who are obese BMI >!30kg/m2. History taking and complete examination were done to all patients.
Results: There was a statistical significant difference between 3 groups regarding length of labour in vaginal deliv-eries, obese women appeared to have a significantly longer length of labour compared with over wight and normal weight women. Regarding the rate of cesarean deliveries and assisted vaginal delivery was significantly increased with the increase in BMI. The overall cesarean section rate was 31.5% in obese women compared with 11.5% and 8.8% in overweight and normal weight women respectively, the assisted vaginal delivery rate is 4.8% in obeses women. In addition to increase feto-maternal complications.
Conclusion: Maternal obesity carries significant risks for the mother and foetus, including increased incidence of prolonged length of labour, complicated delivery and cesarean section, low Apgar score and macrosomia with possibility of shoulder dystocia.
