Cardiometabolic disease and depression link to daily disability
In a longitudinal study of 16,780 older adults over eight years, cardiometabolic multimorbidity and depression together were tied to steeper rises in daily living disability.
Scientific Reports
In a longitudinal study of 16,780 adults aged 45 and older from the China Family Panel Studies tracked between 2012 and 2020, researchers assessed how cardiometabolic conditions and depression relate to instrumental activities of daily living disability. Both cardiometabolic disease and depression were independently associated with higher disability scores. Individual cardiometabolic disease, cardiometabolic multimorbidity, and depression were each linked to higher risks of new-onset and persistent disability, a greater likelihood of severe disability trajectories, and a reduced likelihood of recovery. When cardiometabolic multimorbidity and depression occurred together, the combination showed evidence of additive and multiplicative interactions associated with further worsening of disability outcomes.
Why it matters
The findings suggest that physical and mental health conditions jointly compound functional decline during aging. Addressing both cardiometabolic disease and depression together may be critical for preserving functional independence in older adults.
Caveats
The findings come from an observational longitudinal study, which cannot determine causality, and the analyses rely on survey-based self-reports.
