2009年某县煤工尘肺流行病学调查分析

目的:观察某县2009年煤工尘肺患病情况及其影响因素,为制定相应的预防措施、降低煤工尘肺的患病率提供理论依据.方法:对某县2009年煤工尘肺患病情况进行分析.结果:某县2009年煤工尘肺患病率3.89%,以Ⅰ期煤工尘肺为主.不同工种煤工尘肺患病率不同.掘进325.45%,采煤工3.53%,井下运输工1.19%,其他工种1.52%,各工种间煤工尘肺患病率差异均具有显著性(P<0.05).煤工尘肺患者的平均接尘工龄为10年,以接尘工龄5～15年患病率最高,患病率与接尘工龄呈正相关(R=0.81,P<0.05);接尘工人各工龄段.主要以Ⅰ期煤工尘肺为主.但随着接尘工龄的增加Ⅲ期煤工尘肺的患病率也在增加(P<0.05).结论:某县2009年煤工尘肺患病率较低,以Ⅰ期煤工尘肺为主;不同的工种之间煤工尘肺的患病率不同,其中以掘进作业工人患病率最高;接尘工龄越高,煤工尘肺患病率越高.病情也越严重.

Epidemiological analysis of coal worker's pneumoconiosis in a county in 2009

Objective：To investigate the incidence of coal worker＇s pneumoconiosis in a county in 2009 and its influence factors for the development of appropriate preventive measures to reduce its incidence and provide a theoretical basis.Methods：The prevalence of pneumoconiosis in the miners in a county in 2009 was collected and analyzed with statistical software SPSS11.5.Results：In this county,the incidence rate of pneumoconiosis in coal workers was 3.89%,mainly phase Ⅰ,which was different in different types of work.The highest incidence was the excavation work（5.45%）,followed by coal-mining workers（3.53%）,underground transportation workers（1.19%）and other types of work（1.52%）.The incidence rate had significant difference among various types of work（P0.05）.The average working years receiving dust were 10 years,5-15 working years receiving dust had the highest incidence rate,showing the incidence rate was positively related with the working years（R=0.81,P0.05）.Among various working years section in the workers receiving dust,the phase Ⅰpneumoconiosis was main,the incidence rate of phase Ⅲ pneumoconiosis was also increased with the increase of working years receiving dust（P0.05）.Conclusion：The morbidity of pneumoconiosis in this county in 2009 was lower,mainly phase I,which is different among various types of work and highest in the tunneling workers.The longer the working years receiving dust,the higher incidence rate of coal worker＇s pneumoconiosis and the more severe condition.
