experimental epidemiology的意思|示意

Experimental epidemiology是一种使用实验设计和统计学分析方法来研究环境因素对健康状况及其影响的研究领域。通常，它用于验证历史性、观察性和模式分析中提出的健康暴露-疾病关系（HDR）以及研究不同对策和干预措施对减少健康风险的效果。

Experimental epidemiology employs a variety of study designs, including cohort and case-control designs, clinical trials, and community interventions, in order to accurately measure levels and effects of exposures to a particular agent or set of agents. It also evaluates the effectiveness of various preventive measures.

使用experimental epidemiology进行研究时，设计师将确定和测量暴露水平，跟踪受试者和测量与暴露的相关疾病结果，同时考虑潜在的混杂因素，以评估暴露与结果之间的关系并对干预措施进行评估。

Experimental epidemiology can be used in a variety of settings and contexts, from the study of vaccine-preventable diseases in healthy populations to the long-term effects of air pollutants in large cities. It is also a useful tool for public health practitioners, as it can provide insights into the real-world effectiveness of prevention and treatment measures.
