Women in less affluent areas of Chicago less likely to reside near mammography facility

October 29, 2012

Women in socioeconomically disadvantaged and less affluent areas of Chicago were less likely to live near a mammography facility with various aspects of care compared with women in less socioeconomically disadvantaged and more affluent areas. This finding could be a contributing factor to the association between disadvantaged areas and late-stage breast cancer diagnosis, according to data presented at the Fifth AACR Conference on The Science of Cancer Health Disparities, held Oct. 27-30, 2012.

"Other research has found that women living in disadvantaged neighborhoods are more likely to be diagnosed with more biologically aggressive forms of breast cancer," said Jenna Khan, M.P.H., a doctoral candidate in epidemiology at the University of Illinois at Chicago Division of Epidemiology and Biostatistics. "The disproportionate lack of access to high-quality screening for these women who may actually need it the most is likely to be contributing to racial and socioeconomic disparities in breast at diagnosis and survival."

Khan and colleagues, in collaboration with the Metropolitan Chicago Task Force, defined an index of social disadvantage from the 2010 census tract data on the percentage of families below the , families receiving public cash assistance or , unemployed persons and female-headed households with children.

They created an index of affluence based on the percentage of families with incomes of $100,000 or more, adults with at least a college education and adults with white-collar jobs.

Their data revealed that when compared with tracts considered to be less socially disadvantaged, more socially disadvantaged tracts were less likely to be located near any facility (47 percent versus 66 percent), facilities designated as American College of Radiology-accredited Centers of Excellence (BICOE; 7 percent versus 36 percent), facilities that offer diagnostic (44 percent versus 52 percent), facilities with at least one breast imaging-dedicated radiologist (31 percent versus 60 percent) and facilities with digital machines (32 percent versus 53 percent).

Similarly, those tracts designated as less affluent were less likely than more affluent tracts to be located near any facility (30 percent versus 77 percent), BICOE-designated facilities (1 percent versus 37 percent), facilities that offer diagnostic mammography (23 percent versus 61 percent), facilities with at least one breast imaging-dedicated radiologist (27 percent versus 71 percent) and facilities with digital machines (16 percent versus 61 percent).

"We recognize that geographic access is only one potential barrier in accessing facilities with quality mammography screening," Khan said. "Other factors, such as insurance status, beliefs about screening and competing priorities, also affect access and utilization of mammography screening."

The study was funded by the Susan G. Komen for the Cure Postbaccalaureate Training in Disparities Research Grant, awarded to the University of Illinois at Chicago.

The non-uniform distribution of mammography facilities among the population would seems to be more a function of the decisions made by those who choose to purchase, set-up, install, and operate the equipment than on the local demography per se. Given the expense involved, economic factors will inevitably contribute to the decision-making process in a major way.
