Researchers at Rush University Medical Center reviewed published literature examining disparities among racial groups in accessing mammography-screening services. They found that women with lower socioeconomic backgrounds, the uninsured, women without a usual source of care, the elderly, recent immigrants, women in rural areas and some racial/ethnic minorities such as Native Americans/Alaskan Natives and Hispanics obtained mammography screenings at a markedly lower rate than the rest of the population.
"We also found that there is evidence that the actual magnitude of these disparities, particularly among low-income racial/ethnic minorities, is underestimated and that disparities persist for some subpopulations of Asian Americans/Pacific Islanders and African Americans," said Dr. Monica Peek, internist at Rush University Medical Center and author of the study.
Peek explained that the national surveys that estimate health behavior in the United States -- The Behavioral Risk Factor Surveillance Survey (BRFSS) and the National Health Interview Survey (NHIS) -- under sample ethnic minorities, particularly those at risk for under-screening. The BRFSS study is primarily a telephone survey, and this method under-samples those who may not have telephones such as persons living in the southern United States, African Americans, Hispanics and Native Americans. Additionally, the questionnaires are typically given in English, and those who are not proficient in English are not eligible to take the survey.
Peek pointed out that in the BRFSS study, only 11.2 percent of women surveyed were uninsured; 75.4 percent were white; 9.7 percent African Americans; 11.1 percent Hispanics,
