Objective:
To investigate the association between neighborhood disadvantage and visual difficulty and blindness.
Approach:
- Study Design: Cross-sectional study analyzing data from over 83,000 census tracts across the United States from 2018 to 2022.
- Data Sources: Utilized the National Neighborhood Data Archive and the American Community Survey.
- Measures: Neighborhood disadvantage was assessed using economic indicators; visual difficulty and blindness were based on self-reported responses.
Key Findings:
- Increasing neighborhood disadvantage is associated with higher prevalence of visual difficulty and blindness.
- Each 0.01-unit increase in neighborhood disadvantage correlates with a 2.9% increase in the odds of visual difficulty and blindness.
Interpretation:
Limitations:
- Reliance on self-reported visual difficulty and blindness rather than clinical testing.
- Exclusion of census tracts with missing visual difficulty and blindness measures may affect generalizability.
