Objective The aim of this study was to evaluate the association
between prepregnancy BMI, and adverse maternal
and neonatal outcomes.
Method In this retrospective cohort study 916 consecutive
singleton gestations were included who gave birth between
1 January 2006 and 31 August 2006 at the Department of
Obstetrics and Gynecology, University of Udine, Italy. Statistical
analysis was performed using univaried logistic
regression and measured by odds ratio.
Results The obese patients had a statistically, signiWcantly
increased incidence of Caesarean section (OR = 2.17,
p = 0.009). Women with overweight (OR = 2.43, p = 0.002)
and obese weight (OR = 4.86, p < 0.0001) were at increased
risk for preterm deliveries. The pre-eclampsia and the fetal
macrosomia ( ̧4,000 g) were increased in obese women
(OR = 5.68, p < 0.0001; OR = 2.58, p = 0.033, respectively).
Conclusion Maternal prepregnancy obesity is signiWcantly
associated with increased risk of Caesarean section,
preterm delivery, pre-eclampsia and macrosomia.
