Study Finds Link Between Food Insecurity and Chronic Illness in Rural Texas

Researchers at the Parkland Center for Clinical Innovation examined rural Texas census tracts and found food insecurity is a major driver of chronic illness rates, tying into earlier findings that over 80% of Texas's rural population lives in areas highly vulnerable to life-threatening disease. The study identified 149 rural census tracts where food insecurity is a baseline problem, using SNAP usage as its measure, and found 192 tracts with high or very high obesity vulnerability.

The report notes that 21.3% of Texans reported food insecurity between 2020 and 2022, compared to 15.5% nationally, and that 58 Texas counties qualify as food deserts. In East Texas specifically, researchers counted only 33 supermarkets serving roughly 150,000 residents, alongside just 182 inpatient hospital beds within 100 miles.

PCCI staff described the mechanism as a domino effect: limited access pushes people toward fast food and shelf-stable options over perishable produce, compounding over time into obesity and related disease. The center says it plans to give the underlying tool to more than 200 community organizations over four years so they can target resources at the block-group level rather than guessing by zip code.
