New research to be published in BJOG: An International Journal of Obstetrics and Gynaecology points to a strong association between maternal obesity and adverse pregnancy outcomes.
Previous research has shown that maternal obesity is associated with pregnancy complications such as hypertensive disorders, gestational diabetes and maternal death; and fetal/neonatal complications such as stillbirth, birth defects, macrosomia (big baby syndrome) and shoulder dystocia.

There was strict selection and researchers looked at the records of 23,316 pregnant women from 15 centres in nine countries. All participants had their BMI measured and underwent a standard oral glucose tolerance test (OGTT) between 24 and 32 weeks gestation. Samples of their random plasma glucose (RPG) were taken at 34 – 37 weeks.
