Blood pressure measurements were obtained among 92,074 persons in Milwaukee between 1974 and 1976 by the Milwaukee Blood Pressure Program. Systolic hypertension was more prevalent in young white men than blacks below 25 years of age, was more common in middle-aged blacks than whites, and was equally prevalent among all persons past 65 years. Diastolic hypertension was more prevalent in blacks than whites of all ages. Whereas the prevalence of systolic hypertension in the population increased with age and was present in a majority or near majority of persons past 65 years, the prevalence of diastolic hypertension rose until the sixth decade, after which it declined. Hypertension was primarily of a diastolic variety in young blacks, whereas systolic hypertension was a prominent feature in young whites.
1974年至1976年间，密尔沃基血压项目对密尔沃基的92074人进行了血压测量。收缩期高血压在25岁以下的年轻白人男性中比黑人更普遍，在中年黑人中比白人更常见，在65岁以上的所有人中患病率相同。舒张期高血压在各年龄段的黑人中比白人更普遍。虽然人群中收缩期高血压的患病率随年龄增长而增加，在65岁以上的大多数或接近大多数人中都存在，但舒张期高血压的患病率在第六个十年之前上升，之后下降。高血压在年轻黑人中主要是舒张期类型，而收缩期高血压是年轻白人的一个突出特征。
