An Exploratory Framework to Interpret County-Level Indicators of Food Insecurity

Area of Science:

• Public Health
• Sociology
• Health Policy

Background:

• Food insecurity (FI) affects 12.5% of the US population, with significant regional disparities.
• County-level FI is linked to poverty but requires a more complex understanding.
• Existing frameworks may not fully capture the multifaceted nature of FI.

Purpose of the Study:

• To develop a nuanced framework for understanding factors contributing to county-level food insecurity.
• To explore the relationship between FI and metrics in food access, affordability, health environment, and county innovation.
• To identify potential population-level health metrics associated with FI.

Main Methods:

• Exploratory study design analyzing 32 counties stratified by high/low FI and poverty rates.
• Evaluation of 14 metrics across four domains: food access, food affordability, overall health environment, and county innovation.
• Utilized publicly available, population-level health data for analysis.

Main Results:

• A stronger overall health environment was significantly correlated with lower food insecurity.
• No significant correlations were found between FI and the summary domains of food access, food affordability, or county innovation.
• This initial study provides a conceptual framework for FI markers.

Conclusions:

• The overall health environment appears to be a key factor associated with reduced food insecurity.
• Further research with expanded samples and metrics is needed to refine this framework.
• Publicly available health metrics can offer insights into complex social determinants like FI.
