PURPOSE Although few studies have explored age-related health care disparities, some researchers have asserted such disparities uniformly disfavor the elderly and are largely attributable to ageism in the health care system. We compared agerelated patterns of screening for colorectal cancer with those for breast and prostate cancer in persons aged 50 years and older.
METHODSWe analyzed data for all adults aged 50 years and older (N = 88,213) in the 2001 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative, telephone-administered survey of personal health behaviors. Main outcome measures were adjusted prevalence by 5-year age-groups of colorectal cancer screening using fecal occult blood testing, fl exible sigmoidoscopy, or colonoscopy for men and women; rates of mammography screening for women; and rates of prostate-specifi c antigen (PSA) screening for men.
RESULTSAfter adjustment for race/ethnicity, education level, income, health insurance, and self-rated health, predicted reported colorectal cancer screening (all modalities) increased signifi cantly from when patients reached age 50 years until 70 to 74 years (66.0%, standard error [SE] 0.8%), remained constant until age 80 years, and then declined. The age-related gain in colorectal cancer screening was confi ned to whites among patients older than 60 years. Reported PSA screening increased until age 75 to 79 years (79.3%, SE 1.1%) and then declined, whereas reported mammography screening peaked at age 55 to 59 years (83.3%, SE 1.2%) and then declined.CONCLUSIONS Signifi cant age-related disparities appear to exist for both evidence-based and non-evidence-based cancer-screening interventions. The issue of age-related disparities in cancer screening is complex, with the direction of disparity favoring the elderly for some services yet disfavoring them for others. 1 Most research has concerned racial or ethnic and economic disparities, 2,3 whereas age-related disparities have received less attention. Some evidence does suggest there are age-related disparities disfavoring the elderly in health care access, 4,5 provider-patient communication, 6-8 and the delivery of certain diagnostic 7,9-13 and therapeutic 5,7,9,10,[14][15][16][17][18] interventions, and may contribute to poorer treatment outcomes. 19 Because older adults constitute a large and rapidly growing subpopulation, 20 age-related disparities in health care merit increased attention.Although the causes of age-related disparities in care remain unclear, some researchers [21][22][23][24][25][26] however, previous studies suggest such disparities might not be the case. Mammography rates do appear to be lower in older than in younger women, 11,[28][29][30][31] even though regular mammography in older women could eliminate age-related disparities in breast cancer survival. 32 By contrast, screening rates for prostate cancer by serum prostate-specifi c antigen (PSA) testing appears to be higher in men older than 70 years than in those 50 to 65 years old, 33,34 even t...
