An epidemiological study was conducted of geographic differences in stroke mortality between the following areas within the United States: Savannah, Georgia (high stroke rates), Hagerstown, Maryland (intermediate stroke rates) and Pueblo, Colorado (low stroke rates). Population samples 35-54 years of age of the three cities were drawn for interview and examination to determine medical conditions and living habits of these populations. The population samples were compared with emphasis on possiblerisk factors for stroke: serum cholesterol and glucose tolerance test determinations, weight and height measurements, blood pressure and cigarette smoking. The gradient of increasing prevalence of stroke-related risk factors from low to intermediate to high for the three cities was present for blood pressure in black females and white males and for glucose tolerance tests in whites and nonwhites. No other consistent pattern of increasing prevalence of risk factors for stroke was evident.
