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, significantly 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 significantly associated with increased risk of Caesarean section, preterm delivery, pre-eclampsia
and macrosomia.
