Comparison of universal screening for gestational diabetes mellitus between one‐step and two‐step method among Thai pregnant women: A randomized control trial

The one-step method can markedly increase the prevalence of GDM to nearly three times that of the two-step method, leading to a substantial increase in care costs and burdens without clear benefits. Convincingly, the one-step method as a new approach may not be suitable for universal screening in a busy antenatal care setting, especially in low-resource health centers in developing countries or among populations with a high prevalence of GDM.
