2006至2009年浙江省尘肺发病分析

Analysis of new pneumoconiosis cases during 2006-2009 in Zhejiang province

目的分析浙江省尘肺发病特点，为制定浙江省尘肺防治策略提供依据。方法通过浙江省职业病网络报告系统收集2006至2009年新发尘肺病例资料，就患者分布地区、行业、发病年龄、接尘工龄、期别、企业规模等特点进行分析。结果2006至2009年，浙江省报告新发尘肺分别为157例、173例、209例和280例，共819例，其中，矽肺占86．9％。尘肺病例主要分布在宁波市、温州市等地区；分布行业以建材、机械、煤炭、地质矿产、轻工、建设为主。新发尘肺患者发病年龄分别为（47．8±10．0）、（52．5±13．1）、（55．5±11．2）、（55．9±12．2）岁，发病年龄呈逐年增长的趋势，差异有统计学意义（P〈0．05）。新发尘肺患者的接尘工龄分别为（12．4±8．6）、（12．9±9．4）、（12．4±8．6）和（15．7±10．0）年。Ⅰ、Ⅱ、Ⅲ期尘肺患者的接尘工龄分别为（14．3±9．87）、（12．4±8．7）、（11．4±7．1）年，差异有统计学意义（P〈0．05）。结论浙江省新发尘肺病呈逐年增长的趋势，以矽肺为主，其分布与区域和行业有关，且接尘工龄较短。

Objective To analyze the characteristics of pneumoeoniosis cases in Zhejiang province and to provide the evidence for pneumoconiosis control and prevention measures in Zhejiang province. Methods The data of new pneumoconiosis cases were from national surveillance system of occupational disease in Zhejiang province during 2006-2009, and were analyzed for distribution, age, exposure duration, pneumoeoniosis phases and enterprise types. Results During 2006-2009, 819 new pneumoconiosis cases （173, 157, 209 and 280 cases, respectively） were reported, 86.9% cases suffered from silicosis. Most of pneumoconiosis cases were distributed in Ningbo, Wenzhou areas and in building materials, machinery, coal, geological and mining, light industries and construction enterprise. The average ages of new pneumoconiosis cases were （47.8±10.0）,（52.5±13.1）,（55.5±11.2） and （55.9±12.2） years old, respectively and showed a significant increase trend （P〈0.05）. The average exposure duration of new pneumoeoniosis cases were （ 12.4± 8.6 ）, （ 12.9±9,4 ）, （ 12.4±8.6 ） and（ 15.7± 10.0） years. The average exposure duration of phase Ⅰ, phase Ⅱ, phase Ⅲ new pneumoconiosis cases were（14.3±9.87）, （12.4±8.7） and （ 11.4±7.1 ） years, respectively and there were significant differences （P〈0.05）. Conclusion New pneumoconiosis cases in Zhejiang province are increasing year by year, the main type of pneumoconiosis is silicosis, the distribution of pneumoconiosis cases is associated with the areas and enterprises, and the exposure duration of new pneumoconiosis cases is relatively shorter.
