Applications of epidemiologic methods to podiatric medicine.

National statistics show that the burden of occupational foot problems is large. For example, over 20 per cent of work-related injuries occur in the lower extremities. However, to date few epidemiologic studies have been undertaken to document the nature, frequency, and causes of occupational foot problems. More are clearly needed. The results of such studies could profitably be disseminated among occupational health professionals to increase their awareness of this relatively neglected aspect of worker health.
