Abstract
The occurrence of both hypertension and diabetes in patients at a general medical clinic at a university center and within a work-site community was determined. In addition, the course of such patients for 4 yr following presentation was observed. The combination of hypertension and diabetes appeared more frequently, was expressed by greater severity, and coincided with a higher observed morbidity among the hospital clinic patients than among the work-site population. These findings regarding the prevalence and natural history of these coexistent diseases reaffirm that the source of a selected population can significantly affect the pattern of disease expression observed and, therefore, limit the capacity to extrapolate results from 1 population to another.This publication has 1 reference indexed in Scilit:
