Despite guidelines recommending that women aged 40 years and older undergo screening mammography at least biennially, reports find that many women do not adhere to these recommendations. The authors' objective was to investigate the factors associated with undergoing a screening mammography. Eligible women were enrolled in Medicare during 2004 and 2005 and resided in North or South Carolina. Information on morbidities, demographics, and physician visits were assessed as predictors for whether a woman underwent a screening mammography. Approximately 50% of the women included in the study had undergone a screening mammography during the study period. An increasing number of physician visits was positively associated with having a screening mammography. Women making at least 1 visit to a gynecologist were more likely to be screened compared with women who saw only a primary care physician and/or a medical specialist. Older age, having certain morbidities, and Medicaid eligibility were inversely related to being screened.
