Mississippi researchers link diabetes rates to local food and safety gaps

Residents in parts of the Deep South face a higher risk of developing diabetes when their neighborhoods lack affordable food, safe places to exercise, and easy access to medical care. A new study from the University of Mississippi and South College identifies these community factors as key drivers of the disease in the region.

The research, published in the Journal of Racial and Ethnic Health Disparities, analyzed data from 418 counties across five Southern states: Mississippi, Louisiana, Alabama, Georgia, and South Carolina. The team mapped diabetes prevalence against local conditions such as poverty rates, food security, and the availability of public parks and primary care clinics.

More than 40 million Americans currently live with diabetes, a condition that is most common in the Deep South. The study challenges the common view that preventing the disease is solely a matter of individual discipline. It argues that the physical and economic environment often determines whether healthy choices are practical for residents.

Ruaa Al Juboori, an assistant professor of public health at Ole Miss, noted that individual behaviors only tell part of the story. She explained that looking at the geography of the disease reveals the surrounding conditions, including access to nutritious food and community safety. Her team found that areas with high diabetes burdens often coincide with gaps in these specific community resources.

The Mississippi Delta emerged as a distinct hotspot in the data. In this region, high rates of diabetes overlapped with significant challenges, including deep poverty, physical inactivity, and a lack of access to public parks. Al Juboori emphasized that looking beyond statewide averages is necessary because different communities have different needs and resource levels.

Precious Patrick Edet, an assistant professor of public health, said the findings suggest that environments shape the opportunities people have to make healthy choices. She noted that while eating well and exercising are important, they are difficult to sustain in areas with economic hardship and limited infrastructure. The study found that counties with higher levels of poverty and food insecurity tended to have higher diabetes prevalence.

Diabetes remains the most expensive chronic condition in the United States, placing a heavy financial burden on both the healthcare system and patients. The researchers argue that prevention efforts may be more effective if they address community-level gaps rather than focusing only on individual habits. Al Juboori stated that prevention planning should ask whether residents have affordable food, accessible care, and safe places to be active.

The study also identified "cold spots" in the Deep South. These are counties with lower-than-expected diabetes rates despite facing similar levels of poverty and healthcare constraints as the hotspots. Neva Agarwala, a researcher at South College, said these areas warrant further investigation to understand what local strengths or services might be contributing to better health outcomes.

Patrick Edet cautioned that there is no one-size-fits-all solution to reducing diabetes rates. She advised local leaders to work directly with residents and healthcare providers to identify specific local needs. The goal is to direct resources toward filling the gaps in community infrastructure that the data has revealed.
