Multi-dimensional social frailty index for predicting disability and mortality in community-dwelling older adults: JAGES cohort

Key Points

• Disability and mortality risk can be predicted using a multi-dimensional social frailty index, enhancing understanding of community-dwelling older adults.
• The study highlights a significant correlation between a 1-point increase in the social frailty index and higher odds of disability and mortality.
• Cohort study analyzed data from the Japanese Aging Cohort Study (JAGES), focusing on community-dwelling older adults aged over 65.
• Findings may inform future frameworks for assessing social frailty, though external validation is needed to strengthen the model.
