Breast and cervical cancer screening in older women: the San Diego Medicare Preventive Health Project.

Abstract

BACKGROUND. This study presents rates and correlates of cancer screening, including mammography, clinical breast exam, breast self-examination, and Pap tests, in older women. Age was the predictor of main interest. RESULTS. Among a sample of female Medicare beneficiaries ages 65 and older, who were members of a health maintenance organization, there was a significant, inverse relationship between age and mammography adherence, while controlling for health status, physician utilization, education, and income. The proportions of subjects ages 65-74 and 75+ never having had a mammogram were 17 and 32%, respectively, and the proportions having had annual mammograms were 40 and 28%, respectively. Pap test frequency showed a trend toward an inverse relationship with age, controlling for demographic and health-related variables. In the youngest age group (65-69), 52% had annual Pap tests, whereas in the oldest group (80+), only 36% had annual Pap tests. Age did not predict frequency of clinical breast exam, and the relationship of age to breast self-examination was inconclusive. The role of the physician in promoting cancer screening is discussed.
