Hypothesis
This study examines the association between socioeconomic status and changes in physical function in older adults.
Conclusion
Low socioeconomic status is linked to poorer physical function in older adults, with age-specific differences in the mechanisms involved.
Supporting Evidence
- Low SES was related to poorer physical function during nine years of follow-up.
- Behavioral factors explained much of the SES differences in physical function in younger-old adults.
- Psychosocial factors reduced SES differences most in older-old adults.
Takeaway
People with less money or education tend to have more trouble moving around as they get older, especially if they are younger than 70.
Methodology
Data were collected from 2,366 participants aged 55-85 over nine years, measuring physical function and socioeconomic status.
Potential Biases
Attrition was associated with lower SES and worse physical function, potentially biasing results.
Limitations
Loss to follow-up due to mortality may have led to an underestimation of the association between SES and physical function.
Participant Demographics
Participants were aged 55-85, with a mix of education and income levels.
