累积率([∑(P_i×I_i)]×100%)和累积危险性({1-e~(1[∑(P_i×I_i)])}×100%)已见于肿瘤统计和流行病学研究中。这类低发病率疾病的累积率在1%以内计算结果,与累积危险性计算结果一致;而累积率在30%以外者,与累积危险性比较,误差增大,不宜使用。心血管病属于低发病率疾病,累积率往往在10%以内,故可使用上述二种指标。因其计算简便,直观性强,容易掌握,因此,在心血管病防治区,做好日常疾病的发病,死亡登记报告制度,计算累计率,累积危险性,相当于Cohort观察研究,可获得系统的数据,以阐明危险因素的强弱变化和作用程度。
Cumulative rates ([Σ (P_i × I_i)] × 100%) and cumulative hazard ({1 -e ~ (1 [Σ (P_i × I_i)])} × 100% have been observed in the study of Tumor Statistics and Epidemiology in. The accumulative rate of such low-incidence diseases is calculated within 1%, which is consistent with the cumulative risk calculation results. When the cumulative rate is less than 30%, the error increases with the cumulative risk and should not be used. Cardiovascular disease is a low incidence of disease, the cumulative rate is often less than 10%, it can use the above two indicators. Because of its simple calculation, intuitive and easy to grasp, so in the prevention and treatment of cardiovascular disease area, do a good job of daily disease incidence, death registration reporting system, calculate the cumulative rate, cumulative risk, equivalent to Cohort observation and research, access to systematic Data to clarify the strength and weakness of risk factors and extent of action.
