Author Information

Primary Institution: Yale University

Hypothesis

Does stress accumulation and physical activity mediate the relationship between perceived neighborhood disorder and cognitive health in older adults?

Conclusion

Higher levels of perceived neighborhood disorder are linked to poorer cognitive health in older adults, with physical activity playing a small mediating role.

Supporting Evidence

  • Higher perceived neighborhood disorder is associated with lower cognitive scores.
  • Physical activity accounts for a small portion of the cognitive decline linked to neighborhood disorder.
  • Allostatic load did not show a significant mediating effect on cognitive health.

Takeaway

Living in a messy or unsafe neighborhood can make older people forgetful, but staying active can help a little.

Methodology

Data from the Health and Retirement Study was used, employing propensity score matching and causal mediation analyses.

Potential Biases

Potential biases may arise from self-reported measures of neighborhood disorder and cognitive function.

Limitations

The study may not account for all individual-level characteristics that could influence cognitive health.

Participant Demographics

Older Americans aged 65 years and older without dementia at baseline.
