Further findings

Predictors of postpartum dysglycaemia

Higher 1 and 2-hour glucose on early pregnancy OGTT, previous GDM and greater gestational weight gain independently associated with postpartum dysglycaemia (logistic regression)
Women with dysglycaemia more likely to have past GDM, lower BMI, more gestational weight gain
