The nature of pregnant women has changed in recent years: women are more likely to give birth at an older maternal age, and more women are likely to be obese when they become pregnant. Not only have older age and higher weight increased the number of women with pre-existing type 2 diabetes who become pregnant, they are also associated with an increased prevalence of gestational diabetes mellitus, which is long recognized as a global health concern [Ferrara, 2007; Vounzoulaki, 2020]. Perinatal morbidity and mortality in pregnancies complicated by diabetes mellitus is much higher than in the general obstetric population, proportionate to the level of glycemic control [Goodman, 2023]. In addition, a diagnosis of gestational diabetes mellitus increases the risk of cardiometabolic diseases (including type 2 diabetes) for both mother and child, in later life [IDF Atlas, 2021; Alba-Linares, 2023]. Consequently it is vital that hyperglycemia is screened for in every woman in pregnancy, through oral glucose tolerance testing and individual consideration of risk factors for the condition (which involve ethnicity, previous history of high-birthweight babies, and family history of diabetes, for example  [IDF Atlas, 2021]). In developing world and/or marginalized community-based populations, optimum screening strategies are unclear [Prüst, 2022; Ramezani Tehrani, 2023]. Consequently, there are unmet needs in real-world clinical care relating to awareness and implementation of guidelines for gestational diabetes screening and management [Vounzoulaki, 2020]. Follow-up screening of women with history of gestational diabetes is necessary to ensure timely identification of pre-diabetes and type 2 diabetes in these high-risk individuals [Björk Javanshiri, 2023].
