第七讲 危险度的测量1 引言 在第四讲中介绍了疾病的测量方法。通过计算发病率、患病率和死亡率等,我们了解到社区人群疾病问题的严重程度,以便确定本社区卫生保健工作的重点。比如某县围产儿死亡率为25.9‰,表明该县的妇幼保健工作应当予以重视。为了减少围产儿死亡,我们就要了解什么暴露因素与该死亡有关及关联的程度大小,这就涉及到几个率的比较。流行病学中采用“危险度”指标来测量暴露与疾病的关联大小。2 比(Ratio)
Chapter VII of the measurement of the degree of risk 1 Introduction In the fourth talk about the measurement of the disease. By calculating morbidity, morbidity and mortality, we understand the severity of the disease in the community in order to determine the priorities of our community’s health care efforts. For example, the death rate of perinatal children in a county is 25.9 ‰, which shows that the MCH work in this county should pay attention to it. In order to reduce the death of perinatal children, we need to know what the exposure factors are related to and related to the death, which involves the comparison of several rates. Epidemiology uses “risk” measures to measure the association between exposure and disease. 2 Ratio
