ABSTRACT=IntroductionWith the increasing aging population, there is a growing need for precise and intelligent health management solutions tailored to older adult individuals. This study proposes a comprehensive digital health management platform that integrates new media technologies to support physical and mental well-being among the older adult.MethodsA personalized health management system was designed by integrating multi-source health data and employing artificial intelligence and blockchain technologies to ensure personalized and secure services. Latent Dirichlet Allocation (LDA) was used to extract topic keywords related to older adult health needs, particularly chronic disease understanding. These text features were then combined with image features extracted via ResNet50 to form a multi-modal feature representation. Finally, an XGBoost-based health risk assessment model was constructed and trained using data from the China Longitudinal Healthy Longevity Survey (CLHLS).ResultsThe LDA+ResNet50 model achieved an average F1 score of 0.926 in classifying five key health-related topic categories, with the highest performance (F1 = 0.97) in the “psychology” domain. The XGBoost model demonstrated excellent classification performance with an accuracy of 0.95, effectively distinguishing between positive and negative health outcomes and capturing complex data patterns.DiscussionThis study demonstrates the feasibility and effectiveness of combining topic modeling, deep learning, and machine learning for older adult health risk assessment. The proposed scheme enhances the accuracy and intelligence of health management services, aiding in chronic disease prevention and improving the overall quality of life for older adult individuals.
