利用国家“八五”科技攻关课题中的１３组人群监测和危险因素调查资料，对监测人群的脑卒中事件急性期死亡率与人群危险因素水平作生态学分析，探讨膳食蛋白质（Ｐｒｏ）、动物蛋白质（ＡＰｒｏ）、盐摄入量与脑卒中死亡率的关系。膳食调查采用连续３天２４小时回忆法，人群监测按照世界卫生组织ＭＯＮＩＣＡ方案进行。自１９９１～１９９５年监测５年，总监测人群２５～７４岁人口累计８２１７１７人。脑卒中年龄标化死亡率：男性为２６／１０万～１６５／１０万，女性为１２／１０万～１３１／１０万。经统计学分析，简单相关显示脑卒中死亡率与摄入膳食营养素中的钠钾比呈正相关，与蛋白质呈负相关，在多元回归分析中控制血压和体质指数后，提示蛋白质特别是动物蛋白质和盐除对血压产生影响外，对脑卒中死亡率有直接作用。
Using the survey data of 13 groups of population surveillance and risk factors in the national “Eighth Five-Year” scientific and technological research project, this paper makes an ecological analysis of the acute mortality and crowd risk factors of stroke in monitoring population, and discusses the relationship between dietary protein (Pro), animal Protein (APro), salt intake and stroke mortality. Meal survey using 24-hour continuous 3-day memory, monitoring of the population in accordance with the WHO MONICA program. Since 1991 ~ 1995, monitoring 5 years, the total population of 25 to 74-year-old population survey 821717 people. Age-standardized death rates for stroke were 26/10 million to 165/10 million men and 12/10 to 131/10 million women. By statistical analysis, simple correlations showed that stroke mortality was positively correlated with sodium-potassium ratio in dietary nutrients and negatively correlated with protein. After controlling for blood pressure and body mass index in multivariate regression analysis, it was suggested that protein, especially animal protein and In addition to the impact of salt on blood pressure, stroke mortality has a direct effect.
