This study examines the influence of factual knowledge of the aged, general attitudes toward the aged, and personal contact with the aged on first-year medical students' attitudes toward geriatric patients and geriatric medicine. Entering medical students indicated a preference for working with younger patients rather than aged patients. Students' attitudes toward the aged were associated positively with their knowledge of the aged, but their interest in geriatric medicine did not appear to be affected significantly by knowledge of, attitudes toward, or personal contact with the aged. The results suggest that factors beyond those considered in this study may need to be examined if there is to be an increase in the number of physicians wishing to care for the elderly.
