Abstract
Objective To compare the risk of cesarean delivery as well as antenatal complications,
complications during delivery and neonatal outcomes between pregnant women with
pre-pregnancy obesity versus normal pre-pregnancy body mass index (BMI).
Study design Cohort study.
Materials and Methods The population studied included pregnant women with singleton
pregnancies of gestational age 37 completed weeks or more who were admitted to labor
room, Chonburi Hospital, from May 1, 2006 to April 30, 2007. All pregnant women with
pre-pregnancy BMI 25 kg/m2 or over were enrolled. The control group included the pregnant
women who were admitted to the labor room next to each studied case and had
pre-pregnancy BMI 18.5-22.9 kg/m2. Patients with previous cesarean delivery, private case
and undelivered were excluded. Cesarean delivery rates as well as maternal and neonatal
outcomes were compared.
Results Six-hundred and forty six patients were enrolled, 323 patients in each group.
Cesarean delivery was significantly higher in obese women (RR 2.3, 95% CI 1.63-3.14). The
risk of cesarean delivery was increased with increasing BMI (RR 2.2 in BMI 25-29.9 kg/m2
and 2.9 in BMI ≥30 kg/m 2). Cesarean delivery due to cephalopelvic disproportion was
significantly higher in the obese group (18% VS 8%, RR 2.23, 95% CI 1.4-3.5). Moreover,
cesarean delivery due to preeclampsia in the obese group was 14-fold. Obese women had
a relative risk of 5.0 (95% CI 2.3-11.1) for pregnancy-induced hypertension and 2.3 (95% CI
1.5-3.5) for large for gestational age (LGA). No significant differences were found between
obesity and the risk of gestational diabetes, placenta previa, abruptio placentae, abnormal
presentation, forceps extraction, shoulder dystocia, 3rd or 4th degree perineal tear, small for
gestational age (SGA), macrosomia as well as low apgar score.
Conclusion Pre-pregnancy obesity is strongly associated with the risk of cesarean delivery as
well as other pregnancy complications and perinatal conditions.
