title: [Study on the response index of population--the prevalence degree of pneumoconiosis].
abstract: Comparison and analysis of the relationship between the prevalence and factors associated with CWP in five collieries, showed that the prevalence rate only reflected the rate of CWP in population and not the category construction of CWP; so, in certain circumstances, it is not suitable to estimate the risk of CWP in different collieries. A new index, the prevalence degree suggested by the authors, is a compound measure of risk of both the prevalence rate and the category construction of pneumoconiosis for population; so, it can reflect the risk of pneumoconiosis comprehensively and sensitively.
