Mammography utilization among Black and White Medicare beneficiaries in high breast cancer mortality US counties

摘要

Background Disparities in US breast cancer mortality between older Black and White women have increased in the last 20 years. Regular mammography use is important for early detection and treatment: its utilization among older Blacks especially in counties with high Black mortality is of interest, but its extent and determinants are unknown.Methods We used Medicare claims for Black and White women 65-74 years old in 203 counties with the highest Black breast cancer mortality. Outcomes over 6 years were as follows: ever mammogram, i.e., > 1 screening mam-mogram, and regular mammogram, i.e., > 3 mammo-grams. With logistic regressions, we examined the independent effect of race on screening controlling for individual- and county-level factors.
