Higher education than parents is linked to healthier aging
In an observational study of over 100,000 older adults across five countries, upward educational mobility was linked to higher overall physical and mental capacity.
Researchers analysed observational data from 100,362 people aged 50 and older across China, Europe, Mexico, South Korea, and the United States. The team tracked intrinsic capacity, a composite measure of thinking, movement, vitality, sensory function, and psychological wellbeing, across 495,028 observations. Across all five regions, people who attained more education than their parents had higher overall intrinsic capacity. In China, Europe, South Korea, and Mexico, this upward educational mobility was also linked to a slower rate of capacity loss over time. In the United States, however, higher education than parents was associated with greater baseline capacity but did not alter the rate of late-life decline.
Why it matters
The findings suggest that social advantages gained early in life may shape how functional abilities hold up in later decades. Understanding these trajectories could help researchers determine how social and economic environments influence healthy lifespan across different countries.
Caveats
Because the study was observational, it cannot determine whether educational mobility directly caused the observed patterns in functional decline. In addition, the analysis relied on combining data from five separate regional surveys that each measure health and social factors within different national systems.
