Cardiometabolic Dysregulation and the Social Determinants of Health in a Food Insecure Population: A Cross-Sectional Study
This cross-sectional study of food-insecure adults in Chicago found a high prevalence of cardiometabolic diseases but no statistically significant associations with neighborhood-level social determinants of health, suggesting that food insecurity itself may be a more dominant driver of these conditions.

In the United States, a group of conditions often called cardiometabolic disease is the leading cause of illness and death. This term covers a cluster of health problems that strike the heart and the body's ability to process energy, including high blood pressure, diabetes, obesity, and unhealthy cholesterol levels. While doctors have long known that what a person eats and how they live their daily life are critical to preventing these issues, scientists are increasingly looking at where people live to understand why some communities suffer more than others. This field of study focuses on social determinants of health, which are the conditions in which people are born, grow, work, and age. These conditions include factors like access to parks, the safety of a neighborhood, and the overall economic well-being of a community. Researchers have found that living in areas with more green space and less crime often leads to better health, while areas with high poverty and deprivation tend to have worse health outcomes. However, a crucial question remains: does the neighborhood environment still matter for people who are already struggling with a severe lack of access to nutritious food?
A team of researchers from Rush University Medical Center set out to answer this question by studying adults who rely on food pantries in Chicago. These individuals are already facing the stress of food insecurity, a situation where people lack reliable access to enough nutritious food for a healthy life. The researchers wanted to see if the specific characteristics of the neighborhoods where these people lived—such as how much greenery was visible from the air, how often violent crimes occurred, and how deprived the area was economically—could explain differences in their heart and metabolic health. They gathered data from 582 adults who visited food pantries on the city's West Side between August 2023 and June 2026. At these events, the participants received free health screenings that included checks for blood pressure, body weight, and blood sugar, along with questions about their medical history and lifestyle.
The results of the screenings revealed a heavy burden of disease within this group. Nearly three out of four participants had high blood pressure, and more than two-thirds had unhealthy cholesterol levels. About half were living with obesity, and roughly one in five had diabetes. Perhaps most striking was that nearly two-thirds of the participants were dealing with two or more of these conditions at the same time. The researchers then looked at the neighborhoods where these participants lived, using data on green space, crime rates, and economic deprivation. They found that the neighborhoods varied widely; some had more trees and parks, while others had higher rates of violent crime and greater economic hardship. Despite these differences, the study found no statistical link between the neighborhood environment and the health conditions of the people living there. Whether a participant lived in a greener area or a more dangerous one did not predict whether they had high blood pressure, diabetes, or obesity.
This lack of connection suggests that for people already facing food insecurity, the immediate crisis of not having enough to eat may be such a powerful force that it overshadows the influence of the neighborhood. It is possible that the stress and physical toll of food insecurity are so severe that they drive health problems regardless of whether a person lives near a park or in a high-crime zone. The study does not prove that neighborhood factors never matter, but it does suggest that in this specific population, the need for food is the dominant factor affecting health. The researchers noted that many participants had conditions they did not know they had, highlighting that these individuals often lack access to regular medical care. The findings point toward the idea that addressing food insecurity itself might be the most effective way to improve health in these communities, rather than focusing solely on changing the neighborhood environment. By screening for food insecurity and cardiometabolic risks together, healthcare providers and community organizations can better identify people who need help and connect them with the resources they require to prevent serious illness.
