Hypothesis
This study aims to investigate the longitudinal association between disability and cognitive decline, and to determine the moderating effects of neighborhood disadvantage among older Mexican Americans.
Conclusion
Neighborhood disadvantage undermines cognitive health among older Mexican Americans who have functional disability.
Supporting Evidence
- There was an average decline of 0.91 in the MMSE score as a function of ADL disability.
- There was an average decline of 0.32 in the MMSE score as a function of IADL disability.
- Significant interactions between ADL and IADL disability and neighborhood disadvantage were observed.
Takeaway
This study found that living in a poor neighborhood can make older Mexican Americans with disabilities lose their thinking skills faster.
Methodology
Data was analyzed using multilevel mixed-effects regression models to estimate cognitive change over time, accounting for socio-demographics and health conditions.
Participant Demographics
Older Mexican Americans without cognitive impairment at baseline.
