Ischemic heart disease (IHD) risk factors and 20-year mortality rates were studied in middle-aged Evans County black males. We hypothesized, a priori, that blood pressure, cholesterol, and smoking would be predictive of mortality in black males; that black-white differences in mortality would be due to differences in risk factor levels and not risk functions per se; and that social status would be associated with risk factor levels and would be a predictor of mortality. Multivariate analyses of cumulative risk of dying and time to death suggest that the major IHD risk factors are predictors of all-cause and IHD mortality in black males. Black-white differences in risk functions, specifically for cholesterol, were explained by social status: black males and lower social status white males had similar risk functions, different from those of higher social status white males. Black males and lower social status white males had almost identical survival curves, each less favorable than those of higher social status white males.
我们对埃文斯县中年黑人男性的缺血性心脏病（IHD）风险因素及20年死亡率进行了研究。我们事先假设，血压、胆固醇和吸烟可预测黑人男性的死亡率；黑人和白人在死亡率上的差异是由于风险因素水平不同，而非风险函数本身的差异；社会地位与风险因素水平相关，且可预测死亡率。对累积死亡风险和死亡时间的多变量分析表明，主要的IHD风险因素可预测黑人男性的全因死亡率和IHD死亡率。社会地位解释了风险函数方面的黑人和白人差异，特别是胆固醇方面：黑人男性和社会地位较低的白人男性具有相似的风险函数，与社会地位较高的白人男性不同。黑人男性和社会地位较低的白人男性具有几乎相同的生存曲线，每条曲线都不如社会地位较高的白人男性的生存曲线有利。
