However, effective tools for identifying GDM are lacking. This study, based on a Chinese cohort, aims to construct and compare the predictive performance of traditional logistic regression (LR) and six advanced machine learning (ML) models, thereby aiding in the early identification and intervention of GDM.\u003Cbr>Methods: This retrospective study utilized medical examination data from 956 singleton pregnant women collected between January and December 2023 from ten maternal and child health hospitals in Pinghu City. We employed receiver operating characteristic curvesand precision-recall curves to assess the predictive performance of the models. Decision curve analysis (DCA) was used to evaluate clinical utility, while calibration curves and Hosmer-Lemeshow (HL) tests were applied to assess the calibration of each model. Results: The 956 participants were randomly divided into a training set and a validation set at a 3:1 ratio. We identified 13 features through Spearman correlation analysis and the Boruta algorithm to construct the models. The LR model exhibited the best AUC at 0.787 (0.723–0.85), outperforming the seven other ML models including RF at 0.776 (0.711–0.841) . Furthermore, the LR model showed good calibration and clinical utility.\u003Cbr>Conclusion: Although ML has tremendous potential, in predicting the occurrence of GDM based on common early pregnancy data, the ML models did not completely outperform the traditional LR model. Simpler, traditional models may be more effective than complex ML approaches.\u003Cbr>Keywords: GESTATIONAL diabetes mellitus, logistic regression, machine learning, first trimester, prediction model |\n| --- |\n| Introduction\u003Cbr>Gestational diabetes mellitus (GDM) is a metabolic syndrome characterized by abnormal elevations in blood glucose levels during pregnancy. Although it typically resolves after childbirth, GDM poses significant short-term and long-term health risks to both mother and child.1 The incidence of GDM exhibits substantial variation across different populationsand has shown a consistent upward trend.2 In the United States, the prevalence of GDM increased from 4.6% to 8.2% between 2006 and 2016, representing a 78% relative increase. This rise was particularly pronounced among Hispanic, non-Hispanic Black women, and women of other races/ethnicities compared to non-Hispanic White women.3 The observed disparities in GDM susceptibility across different racial groups can be attributed to a combination of genetic predisposition, lifestyle factors, and socioeconomic determinants, which contribute to significant variations in incidence |\n\nReceived: 18 December 2024  \nAccepted: 19 April 2025  \nPublished: 26 April 2025  \nInternational Journal of General Medicine 2025:18 2263–2274 2263  \n© 2025 Ni et al.
