ABSTRACT
The study aimed to develop a predictive model using machine learning algorithms, providing healthcare professionals with a novel tool for assessing disability risk in older adults. Data from the 2018 and 2020 waves of the China Health and Retirement Longitudinal Study were utilized, including 3,172 participants aged 65 years and older with no baseline disability. In this study, five machine learning algorithms were employed to construct risk assessment and prediction models for disability in older adults. The Shapley Additive Explanations method was applied to analyze the independent predictors of disability risk. In total, 695 participants (21.9%) were disabled during follow-up. Among the five machine learning models, prediction models constructed using random forest and extreme gradient boosting methods showed superior performance, achieving F1 scores of 0.92 and 0.86 and accuracies of 0.92 and 0.85, respectively. Key predictors of disability risk included self-rated health, education, sleep duration, alcohol consumption, depressive symptoms, hypertension, and arthritis. The Machine learning models for assessing and predicting disability risk in older adults, particularly those developed using RF and XGBoost algorithms, exhibited strong predictive capabilities. These findings highlight the potential of these models for practical application in clinical and public health settings, warranting further exploration and validation.
