PP.34 Impact of Maternal Obesity on Perinatal Outcome in IUGR – The Multicentre Prospective Porto Trial
Year: 2013
Type: article
Abstract: Objective The objective of this analysis, as part of the multicentre prospective PORTO Trial, was to study the effect of increasing maternal BMI on perinatal outcome in IUGR pregnancies. Study design The PORTO Trial recruited 1,118 consecutive ultrasound-dated singleton IUGR pregnancies, defined as EFW < 10th centile. Maternal BMI was recorded at booking and divided into 4 subcategories. Perinatal outcomes were documented for all study participants. Results Of the 1,076 recruited patients with complete records, 693 (64%) were of normal weight (BMI < 25), 258 (24%) were overweight (BMI 25–30), 93 (9%) were obese class I (BMI 30–35) and 32 (3%) were obese class II (BMI 35–40). Obese patients have significantly lower prospect of vaginal delivery and their offspring are at increased risk of adverse outcome (Table 1).
