All women underwent a 50‐g 1‐h glucose challenge test (GCT) at 24–28 weeks of gestation and further underwent a 75‐g 2‐h oral glucose tolerance test (OGTT) if the GCT result was ≥7·8 mmol/l. Women were divided into four groups, i.e., GDM defined by both criteria, GDM defined by the IADPSG's only, GDM defined by the 1999 WHO's only and non‐GDM by either of them. Large for gestational age (LGA), macrosomia, pregnancy‐induced hypertension (PIH) and preterm birth were compared among the four groups. Logistic regression was used to control for confounders.</p> </sec> <sec id="cen12801-sec-0003" sec-type="section"> <title>Results</title> <p>The use of IADPSG's and the 1999 WHO's criteria detected that 7·7% (<italic>n</italic> = 1378) and 6·8% (<italic>n</italic> = 1206) of women had GDM, respectively, with 429 GDM newly identified and 257 women missed by a shift from the 1999 WHO's to the IADPSG's. The IADPSG's newly defined GDM had significantly increased risks of LGA (adjusted OR: 2·23, 95%CI: 1·36–3·64) and macrosomia (2·65, 95%CI: 1·50–4·66) than the 1999 WHO's only defined GDM cases.</p> </sec> <sec id="cen12801-sec-0004" sec-type="section"> <title>Conclusions</title> <p>A shift of the 1999 WHO's criteria to the IADPSG's diagnosed more GDM cases who had worse pregnancy outcomes than those cases missed.</p> </sec> </abstract>
