Beyer KMM, et al. - Researchers investigated large US metropolitan statistical areas (MSAs) for the correlation between housing discrimination and the size of cancer disparities. Data from the US Centers for Disease Control and Prevention were used to determine MSA-level cancer disparities. They assessed mortgage discrimination for each MSA using the Home Mortgage Disclosure Act database and used US Census data to determine MSA racial segregation. Observations revealed geographical variation in black-to-white cancer mortality disparities (rate ratios), ranging from 1.50 to 0.86; 88% of mortality ratios were >1, indicating higher mortality for blacks. They observed a larger gap between black and white cancer mortality rates in areas with greater mortgage discrimination. This trend was not evident in some areas. They suggest examining these exceptions and policies related to housing discrimination in order to assess novel strategies for explaining and eliminating cancer disparities.
