Beaglehole. R. (Epidemiology Unit Wellington Hospital. Wellington, New Zealand).G. Heiss, H. A. Tyroler, J. C. Cassel and C. G. Hames. Prevalence and incidence data in the assessment of the risk of coronary heart disease. Am J Epidemiol 102:55–62, 1975.—Estimates of risk of coronary heart disease (CHD) derived from two prevalence survey examinations and from a 7- to 9-year incidence study were compared using data from the Evans County Cardiovascular study. Four risk factors were studied: sex, blood pressure, age and serum cholesterol; relative risks and morbidity ratios were used as estimators of the risk of CHD. Considerable agreement was found between the estimates of risk derived from the incidence and prevalence data.
