Abstract:

Objective To explore the related factors of intrinsic capacity among community-dwelling older adults and analyze the pathways of these factors，and to provide evidence for improving their intrinsic capacity. Methods Using convenience sampling，308 community-dwelling older adults in Hangzhou were recruited as participants in March 2026. The survey utilized a general information questionnaire，the Brief Aging Perceptions Questionnaire，the Geriatric Health Promotion Scale，and the Intrinsic Capacity Assessment Scale for the Older People. Descriptive statistics，univariate analysis，Pearson correlation analysis，and multiple linear regression analysis were performed using SPSS 26.0 software. Path analysis was conducted using SPSS PROCESS v4.2. Results A total of 300 valid questionnaires were included. The intrinsic capacity score among community-dwelling older adults was（114.95± 7.31） points. Multiple linear regression analysis showed that self-perception of aging，health promotion behaviors，age，and self-rated health status were factors associated with the intrinsic capacity among community-dwelling older adults（P<0.05）. Path analysis indicated that the total effect of self-perception of aging on intrinsic capacity was -0.388，with a direct effect of -0.223. The indirect effect of health promotion behaviors accounted for 42.5% of the total effect（B=-0.165，95%CI：-0.209~-0.122）. Conclusion The intrinsic capacity among community-dwelling older adults is influenced by multiple factors. Healthcare professionals may delay the decline in their intrinsic capacity by reducing negative perceptions of aging and enhancing adherence to health promotion behaviors.
