Frailty Trajectories and Social Integration in Older Adults with COPD, 2024-2025

A prospective longitudinal study of 347 older adults with COPD recruited from a single hospital in China between May 2024 and January 2025. The dataset tracks frailty and social integration across five time points over 12 months, identifying four distinct frailty development trajectories. The research was authored by Li Feng and shared under a CC-BY-4.0 license.

Use Cases

• Modeling heterogeneous frailty progression over time based on repeated assessments.
• Analyzing associations between health trajectories and social outcomes based on three measured dimensions of social integration.
• Training classifiers to stratify patients into frailty trajectory groups using baseline clinical characteristics.

Strengths

• Contains data from 347 patients who completed all five follow-up assessments over a 12-month period.
• Identifies four distinct frailty trajectory classes with specific proportions (e.g., 41.2% Persistently Stable-Low Frailty).
• Associations are analyzed while controlling for baseline social integration, demographic, and clinical variables.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single hospital, which may reflect geographic or institutional bias.
