One of the risk factor that has been a main consideration for selective screening was family history. Family history of diabetes, as in our study, has a higher correlation with occurrence of diabetes15-16. Family history of diabetes mellitus has shown to have an independent significant association with the risk for macrosomia and caesarean section during pregnancy17. It is very striking that as many as one-third of women with diabetes in our study had no antecedent risk factor but was screened for diabetes following detection of glycosuria in pregnancy. The role of universal screening hence should receive full consideration to reduce missed opportunity and minimise adverse outcome of late diagnosis of diabetes in pregnancy.
According to Confidential Enquiry into Maternal and Child Health (CEMACH), 67% of women with DM had a higher incidence of caesarean section, which was mainly iatrogenic as a result of early induction of labour18. A multicentre Italian study on pregnancy outcome in women with diabetes reported the rates of caesarean section and preterm deliveries were higher than in the
