Our aim was to examine the association of White's classification with obstetric and perinatal risk factors and outcomes in type 1 diabetic patients. ⋯ White's classification is useful in estimating the risk of pre-eclampsia in early pregnancy independently of suboptimal glycaemic control and hypertension. However, its utility in predicting adverse perinatal outcomes seems limited when information on first trimester HbA1c, blood pressure and diabetic microvascular complications is available.
