Disaggregation of Green Space Access, Walkability, and Behavioral Risk Factor Data for Precise Estimation of Local...

Area of Science:

• Environmental health
• Urban planning
• Public health research

Background:

• Social and Environmental Determinants of Health (SEDH) framework links human behaviors, health outcomes, and built environments.
• Understanding community-specific factors impacting SEDH is crucial for developing healthier built environments.
• Lack of granular, local-scale data on community characteristics hinders effective planning.

Purpose of the Study:

• To address the unavailability of local-scale data by applying data disaggregation methods.
• To obtain small area estimates for behavioral risk factors and geospatial measures of community environments.
• To provide precise, community-specific insights for researchers and policymakers.

Main Methods:

• Utilized various data disaggregation techniques.
• Generated small area estimates for key behavioral risk factors.
• Quantified geospatial measures of green space access and walkability at the zip code level in Allegheny County, Pennsylvania.

Main Results:

• Spatial distribution and disparities of local characteristics were identified across Allegheny County.
• Zip codes with high behavioral risk factor estimates did not necessarily show superior green space access or walkability.
• Individual income was not directly correlated with better environmental exposures like green space or walkability.

Conclusions:

• Data disaggregation is effective for analyzing complex relationships between community behaviors and built environments with precision.
• This approach is particularly valuable for diverse populations, enabling targeted interventions.
• Integrating data at a common local scale offers crucial insights for public health policy and research.
