Less attention has been paid to socioeconomic risk factors such as residence in food deserts, which represent the confluence of geography and diet. In this study, we describe food access patterns among patients with urinary tract stones receiving care at an academic medical center compared to the broader statewide population. METHODS: All individuals with encounters for stone disease at our institution in calendar years 2016-2018 were identified. Patient demographics including age, gender, ethnicity, BMI, and address at time of encounter were abstracted from the medical record, and patient data were linked to U.S. census tract data using the U.S. Census Bureau’s Geocoder tool. Economic and food access data per census tract were derived from the U.S. Department of Agriculture’s Food Access Research Atlas. Analysis was limited to stone formers in Oregon whose census tract information was compared to Oregon statewide data via Mann-Whitney U test (α<0.05). RESULTS: A total of 787 Oregonian patients were seen for stone disease in the study period. Mean age of these patients was 54 years (SD 17), 51.5% were women, 91.9% were non-Hispanic, and mean BMI was 30.4 (SD 10.8). These patients represented 418 of 830 census tracts in Oregon. One-third of tracts occupied by stone formers were classified as food deserts with no access to a grocery store within 1 mile of residence in urban settings and 10 miles in rural settings (33%). Less than 10% of stone formers (8.6%) met classifications for low income and low food access. Compared to overall state characteristics, stone formers lived in tracts that were more urban (85.5 vs. 71.9% , p<0.001), higher income ($72k vs. $64k, p<0.001), less impoverished (15.7 vs. 16.8%, p=0.003), and with similar food access at 1 mile (31.5 vs. 29.5% food desert status, p=0.38) and greater access at 10 miles (1.5 vs. 5.9%, p<0.001). CONCLUSIONS: Approximately one-third of patients treated for stone disease lived in food deserts as designated by the USDA, and 8.6% lived in areas that were both low income and food deserts. These patients lived in areas that were more urban, higher income, and had somewhat better access to food than average across the state, which likely reflects their ability to access treatment at a tertiary care center. Further research is necessary to clarify the relationship between food access and stone disease across the population.
