Understanding the risk factors associated with prediabetes and T2D can lead to timely interventions to prevent and potentially avert long-term health complications. Objective This study aims to use machine learning algorithms to identify the best anthropometric and demographic characteristics associated with prediabetes and diabetes in Indian children and adolescents ages 10–19.  \nMethods The study utilizes the Comprehensive National Nutrition Survey conducted in 2016–2018 in India. The study sample includes children and adolescents aged 10–19 years. We used nine supervised machine learning algorithms to classify, assess, and identify the best model for ascertaining the risk of diabetes among adolescents in India. Various indices were used to evaluate the classification algorithms, such as the ‘accuracy score’, ‘F1 score’, ‘recall score’, ‘precision score’, and ‘area under the curve’ (i.e. , AUC) . Results were obtained based on the model with higher precision and accuracy in predicting the risk of diabetes among study subjects. Cutoff points for prediabetes were between 5.7 and 6.4 mmol/l and diabetes greater than 6.4 mmol/l.  \nResults The study comprised 12,318 children and adolescents (6333 males and 5985 females) . The prevalence of diabetes and prediabetes in the study population was 11%(n = 1888), while the prevalence of diabetes alone was 0.6%(n = 233) . WHtR was the most crucial feature in predicting prediabetes/diabetes, with an optimum cutoff of 0.62, a sensitivity of 0.93, and an AUC of 0.79.  \nConclusions The findings derived from our machine learning analysis underscore the significance ofWHtR as a cost-effective and valuable tool for diabetes and prediabetes screening among adolescents in India.  \nKeywords Waist-height ratio · Diabetes · Prediabetes · Machine learning · Random forest  \n* Harshal Deshmukh [harshal.deshmukh@jcu.edu.au](harshal.deshmukh@jcu.edu.au)  \nKirti Chauhan  \n[kirti070197@gmail.com](kirti070197@gmail.com)  \nThozhukat Sathyapalan[thozhukat.sathyapalan@hyms.ac.uk](thozhukat.sathyapalan@hyms.ac.uk)[ ](thozhukat.sathyapalan@hyms.ac.uk)Usman Malabu [usman.malabu@jcu.edu.au](usman.malabu@jcu.edu.au)[ ](usman.malabu@jcu.edu.au)Shashank Rameshchandra Joshi [shashank.sr@gmail.com](shashank.sr@gmail.com)  \nShri Kant Singh  \n[sksingh31962@gmail.com](sksingh31962@gmail.com)  \n1 Department of Diabetes, Endocrinology and Metabolism, Allam Diabetes Centre, Hull University Teaching Hospitals, Hull HU3 2PA, UK  \n2 Department of Endocrinology, DM, FACE, MD, FRCP, FACP, Joshi Clinic, Mumbai, Maharashtra, India  \n3 Department of Survey Research and Data Analytics, International Institute for Population Sciences, Mumbai, Maharashtra, India  \n4 James Cook University, Australia, Townsville, QLD, Australia  \n5 Translational Research and Biostatistics, All India Institute of Ayurveda, New Delhi, India  \nIntroduction  \nDiabetes is a leading cause of mortality and morbidity, affecting millions worldwide, including individuals as young as children and adolescents.
