Early detection of potential SI in this demographic is critical. This study investigates the potential of Activities of Daily Living (ADL) as a predictive marker for SI, utilizing data from the 2018 China Health and Retirement Longitudinal Study (CHARLS), which includes 10,136 individuals aged 45 and above. The Barthel Index (BI) was used to assess ADL, and the correlation between ADL and SI was examined through statistical analyses. Machine learning algorithms (Support Vector Machine, Decision Tree, and Logistic Regression) were employed to validate the findings and elucidate the underlying relationship between ADL and SI.  \nBackground: SI poses significant challenges to the health and quality of life of middle-aged and older adults, increasing the demands on community-based and home care services. In the context of global aging, it is crucial to investigate the factors contributing to SI. While the role of ADL as a potential biomarker for SI remains unclear, this study aims to provide new evidence supporting ADLas an early predictor of SI through statistical analysis and machine learning validation.  \nMethods: Data were derived from the 2018 CHARLS national baseline survey, comprising 10,136 participants aged 45 and above. ADL was evaluated using the BI, and SI was assessed based on the CHARLS records of “Speech impediments.”Statistical analyses, including independent sample t-tests, chi-square tests, Pearson and Spearman correlation tests, and hierarchical multiple linear regression, were conducted using SPSS 25.0. Machine learning algorithms, specifically Support Vector Machine (SVM), Decision Tree (DT), and Logistic Regression (LR), were implemented in Python 3.10.2.  \nResults: Analysis of demographic characteristics revealed that the average BI score in the “With Speech impediments” group was 49.46, significantly lower than the average score of 85.11 in the “Without Speech impediments” group. Pearson correlation analysis indicated a significant negative correlation between ADL and SI (r = −0 . 205, p \u003C 0.001) . Hierarchical multiple linear regression confirmed the robustness of this negative correlation across three models (B = −0 .001, β = −0 . 168, t = −16 . 16, 95% CI = −0.001 to −0 .001, p = 0.000) . Machine learning algorithms validated the statistical findings, confirming the predictive accuracy of ADL for S","cbCaim8JcHxNnQc7","https://ap.wps.com/l/cbCaim8JcHxNnQc7","pdf",1954587,1,15,"English","en",105,"# Introduction\n## Background\n# Methods\n## Data and Measures\n## Statistical Analyses\n## Machine Learning Models\n# Results\n## Demographic Characteristics and Correlation\n## Regression Findings\n## Predictive Validation (AUC)\n# Conclusion","[{\"question\":\"What dataset and participant characteristics are used in the study?\",\"answer\":\"The analysis uses the 2018 China Health and Retirement Longitudinal Study (CHARLS) baseline data, including 10,136 participants aged 45 and above.\"},{\"question\":\"How are activities of daily living and speech impediments measured?\",\"answer\":\"Activities of daily living are assessed using the Barthel Index (BI).
