Identifying sunscreen deserts in Cuyahoga County

Abstract

Low sunscreen use in patients of color (POC) is multifactorial and could be partially attributable to lack of access or the lack of knowledge about its use beyond skin cancer prevention. Dyschromia is among the top diagnoses for POC and sunscreen is first-line management. POC and lower socioeconomic status often face health disparities and are susceptible to having difficulty accessing food, health care, and medication. We look to see if they extend to sunscreen access by evaluating physical retailers. This study investigated sunscreen access by identifying potential sunscreen deserts and characterizing sunscreen availability and affordability in Cuyahoga County, Ohio. Sunscreen deserts were defined as census tracts that were both low-income and low-access, adapted from the definition of food deserts. Google Maps search of "sunscreen" and "sunscreen store" in Cuyahoga County identified sunscreen retailers to geocode addresses. Total number and average cost of sunscreens were collected for each retailer and compared by community type. Fisher exact test, analysis of variance, and logistic regression were used for analysis. One hundred forty-six retailers were included in analysis of four hundred twenty-one census tracts in the county. Sixty-seven tracts met the definition of sunscreen desert. Majority White tracts were less likely to be deserts and had more sunscreen formulations, than Majority Black tracts (p < 0.001). The majority of sunscreen deserts were in predominantly black communities, which had fewer stores and sunscreen formulations available. These findings indicate a lack of sunscreen available to a demographic of patients that could benefit from increased access, as it would help manage hyperpigmentation.
