OBJECTIVES: To estimate the national rates of mammography screening in women aged 80 and older and examine the relationship between health status and screening within the previous 2 years. DESIGN: Population-based survey. SETTING: United States. PARTICIPANTS: Eight hundred eighty-two women aged 80 and older who responded to the 2000 National Health Interview Survey, representing an estimated 3.83 million noninstitutionalized women nationally. MEASUREMENTS: Screening mammography, disease burden, and functional status were assessed using a questionnaire. RESULTS: Of the 882 women, 41.5% were aged 85 and older; 19.6% had two or more significant diseases; and 12.1% were dependent in at least one activity of daily living (ADL). More than half (50.8%) had received a screening mammogram within the previous 2 years. Women with two or more significant diseases were less likely to have received screening than those without significant disease, but the difference was not statistically significant (43.9% vs 54.0%, P=.152). Women dependent in at least one ADL were less likely to receive screening mammography than women without functional impairment (37.2% vs 55.9%, P<.001). After adjustment, the likelihood of screening remained lower in women with two or more significant diseases (adjusted odds ratio (AOR)=0.63, 95% confidence interval (CI)=0.40-1.05) and in women with at least one ADL dependency (AOR=0.44, 95% CI=0.22-0.88). Of 294 women likely to have life expectancies of less than 5 years because of poor health, 39.4% received screening mammography. CONCLUSION: More than half of women aged 80 and older in the United States receive screening mammograms. Nearly 40% of women very unlikely to benefit because of poor health received screening mammography.
