This study aimed to determine the optimal diagnostic criteria for GDM in the Emirati population based on predicting adverse perinatal outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 2,449 eligible pregnancies from \u201cThe Mutaba\u2019ah Study\u201d birth cohort were screened using OGTT between 24 and 32 weeks from May 2017 to March 2021. We compared the prediction of adverse perinatal outcomes [Large for Gestational Age (LGA) and Composite Outcome] risk by four GDM diagnostic criteria (IADPSG, NICE2015, WHO1999, and ADIPS1998) using adjusted regression models. We then developed a new GDM diagnostic threshold for this population (using an aOR of 1.75 recommended by the IADPSG consensus panel). The new criteria was validated and compared with other criteria using risk analyses, c-statistic (AUC), integrated discrimination improvement (IDI), and net reclassification improvement (NRI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the four criteria assessed, IADPSG was the best predictor for large for gestational age (LGA) <jats:italic>(aOR 1\u00b777, 95%CI 1\u00b736-2\u00b729)<\/jats:italic> and composite outcome <jats:italic>(aOR 1\u00b749, 95%CI 1\u00b719-1\u00b786)<\/jats:italic>. The newly developed criteria showed even stronger associations than the IADPSG [LGA <jats:italic>(aOR 1\u00b793, 95% CI 1\u00b748-2\u00b753)<\/jats:italic>; Composite Outcome <jats:italic>(aOR 1\u00b762, 95% CI 1\u00b728-2\u00b705)<\/jats:italic>]. The new criteria model had good discrimination properties for LGA prediction <jats:italic>(AUC 0\u00b778; 95%CI 0\u00b768-0\u00b788)<\/jats:italic> and composite outcome prediction <jats:italic>(AUC 0.73; 95%CI 0.57-0.83)<\/jats:italic>. The new criteria model also correctly reclassifies 49.4% of patients based on LGA risk <jats:italic>[NRI; 0\u00b7494 (p=0\u00b7043)]<\/jats:italic>, whereas the IADPSG did not significantly reclassify these patients <jats:italic>[NRI; 0\u00b7202 (p=0\u00b7409)]<\/jats:italic>. For composite outcome prediction, the NRIs for both models were not statistically significant. The new criteria model also improved the discrimination slope (IDI) for LGA prediction by 42.2%, whereas IADPSG improved it by only 9.0%. For the composite outcome prediction, the new criteria model improved by 5.0% vs. IADPSG by 1.3%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Following the development of a new threshold, the GDM diagnostic criteria defined in this study predicted adverse perinatal outcomes better and demonstrated more optimal clinical utility compared with the existing criteria in this population; hence, adopting it could minimize the burden of GDM adverse perinatal outcomes.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2025.1641326","type":"journal-article","created":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T04:19:01Z","timestamp":1760069941000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimizing
