Summary
Short sleep duration is linked to a higher risk of cognitive disability nationwide. This association is particularly strong in Western US states, underscoring the impact of sleep on brain health.
Area of Science:
- Public Health
- Epidemiology
- Spatial Analysis
Background:
- Short sleep duration and adverse Social Determinants of Health (SDoH) are associated with an increased risk of cognitive disability.
- Understanding the spatial relationship between short sleep and cognitive disability is crucial for public health interventions.
Purpose of the Study:
- To determine if spatial associations exist between neighborhoods with short sleep duration and cognitive disability across the United States.
- To adjust for confounding factors including SDoH, demographics, health outcomes, and preventive practices.
Main Methods:
- Spatial analysis using a spatial lag model at the census tract level across the US (excluding Florida).
- Utilized 2021-2022 data from the Centers for Disease Control and Prevention (CDC) and US Census Bureau.
- Adjusted for SDoH, demographics, health outcomes, preventive practices, and the CDC's Social Vulnerability Index.
Main Results:
- A significant positive association was found between short sleep duration and increased risk of cognitive disability nationwide (estimate range [0.29; 1.27], p < 0.005).
- Six Western states (New Mexico, Alaska, Arizona, Nevada, Idaho, and Oregon) showed a significant increased risk pattern (p = 0.007).
Conclusions:
- Short sleep duration is a significant predictor of cognitive disability across the US, even after adjusting for confounders.
- The strong association in the Western US highlights the influence of geographic context and local factors on health outcomes related to sleep and cognition.
