流行病学方法用于一般慢性疾病研究的目的主要是探讨病因。尘肺的病因基本上是明确的。尘肺流行病学研究的主要目的是:(1)描述煤矿的尘肺病情,以发病率,患病率,发病工龄等作为尘肺流行严重性的标志。(2)分析尘肺的流行因素,探讨煤矿生产环境中粉尘的质和量,以及其他物理化学因素的作用,特别是对呼吸系统的影响。(3)在现场,研究粉尘暴露剂量与尘肺的发病的关系,为建立粉尘浓度安全标准提供依据,(4)估计个体的尘肺患病或死亡的危险性,推断煤矿的群体病情,进行尘肺流行的预测。(5)拟定煤矿尘肺的防制对策,考核尘肺防治措施的效果。
The purpose of epidemiological methods for the study of general chronic diseases is mainly to explore the cause. The cause of pneumoconiosis is basically clear. The main purposes of pneumoconiosis research are as follows: (1) Describe the dust pneumoconiosis in coal mines with the incidence, prevalence and length of service as indicators of the severity of pneumoconiosis. (2) Analyze the epidemic factors of pneumoconiosis, discuss the quality and quantity of dust in the coal mine production environment, and other physicochemical factors, especially on the respiratory system. (3) Studying the relationship between dust exposure dose and the incidence of pneumoconiosis in the field, providing the basis for establishing safety standards for dust concentration, (4) Estimating the risk of individual pneumoconiosis or death, inferring the population condition of coal mines and conducting pneumoconiosis Prediction. (5) To formulate the prevention and control measures for pneumoconiosis in coal mines and assess the effect of pneumoconiosis prevention and control measures.
