Mortality trends and risk factors of stroke and ischemic heart disease in Japanese and Chinese population.

收集的信息包括日本的国家生命统计和国家健康与营养调查年度报告以及中国疾病监测点的国家死亡率抽样调查。已通过研究者会议验证和评价了其可用性和有效性。计算并比较了1950-2005年日本和1990-2010年中国脑卒中和缺血性心脏病的标化死亡率，结果显示，1990 - 2010年期间，日本脑卒中死亡率的总体下降幅度大于中国。自2005年以来，脑卒中已成为中国第一位死亡原因，在过去的15年中，缺血性心脏病的死亡率几乎翻了一番。目前正在对两国风险状况的差异进行统计分析。

The collected information included the National Vital Statistics and the Annual Reports of National Health and Nutrition Surveys in Japan and the National Mortality Sampling Surveys in China Disease Surveillance Points. The availability and validity of them have been verified and evaluated through investigator meetings. Standardized mortality rates of stroke and ischemic heart disease (1950-2005 in Japan and 1990-2010 in China) were calculated and compared.The overall decline of mortality from stroke was more prominent in Japan than in China during the period between 1990 and 2010. Stroke became the first leading cause of deaths in China since 2005, and the mortality of ischemic heart disease was almost doubled in the past 15 years in China. Statistical analysis for the disparities of risk profiles between two countries is being conducted.
