Pregnancy Outcomes of Parturients with Excessiveweight in Maharat Nakorn Ratchasima Hospital

Abstract

Objective:To compare the maternal and fetal adverse pregnancy outcomes in parturients with excessive-weight and those with normal weight in Maharat Nakorn Ratchasima Hospital. Design: Retrospective analytic study. Materials and Methods: Data was collected from medical records of 1350 pregnant women, who attended the antenatal care clinic and delivered in Maharat Nakorn Ratchasima Hospital during the first of October 2004 till 30th of September 2006. Body mass index was calculated by using weight at pre-pregnancy period (kg), divided by height (m) squared. The subjects were divided into two groups according to maternal BMI (normal group, BMI 20-24.99 and excessive-weight group, BMI >25). Antenatal complications, intervention during labor, route of delivery, maternal morbidity, birth weight and neonatal outcomes were collected and analyzed. Results:The prevalence of parturients with excessive weight was 16.18% (maternal overweight (BMI 25-29.9) was 11.67% and maternal obesity (BMI >30) was 4.51%). Compared to parturients with normal BMI, the following outcomes were significantly more common in excessive-weight pregnant women (odds ratio (95% confidence interval)): pre-eclampsia 6.99 (3.93-12.44), gestational diabetes mellitus 8.31 (3.22-21.42), preterm delivery 1.53 (1.04-2.27), posterm delivery 1.70 (1.19-2.44), cesarean section 1.33 (1.01-1.75), cephalopelvic disproportion 1.91 (1.32-2.77) and macrosomia 2.61 (1.19-5.74). Conclusion:Parturients with excessive-weight had more significant adverse pregnancy outcomes compared with those with normal weight.
