To analyze the characteristics of pneumoconiosis cases in Zhejiang province and to provide the evidence for pneumoconiosis control and prevention measures in Zhejiang province.
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, pneumoconiosis phases and enterprise types.
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 pneumoconiosis 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).
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.
分析浙江省尘肺病病例特征，为浙江省尘肺病防治措施提供依据。
新尘肺病病例数据来自2006 - 2009年浙江省职业病国家监测系统，对其分布、年龄、接触工龄、尘肺病期别及企业类型进行分析。
2006 - 2009年共报告新尘肺病病例819例（分别为173例、157例、209例和280例），86.9%的病例为矽肺。大部分尘肺病病例分布在宁波、温州地区以及建材、机械、煤炭、地质和采矿、轻工及建筑企业。新尘肺病病例的平均年龄分别为（47.8±10.0）岁、（52.5±13.1）岁、（55.5±11.2）岁和（55.9±12.2）岁，呈显著上升趋势（P<0.05）。新尘肺病病例的平均接触工龄分别为（12.4±8.6）年、（12.9±9.4）年、（12.4±8.6）年和（15.7±10.0）年。Ⅰ期、Ⅱ期、Ⅲ期新尘肺病病例的平均接触工龄分别为（14.3±9.87）年、（12.4±8.7）年和（11.4±7.1）年，差异有统计学意义（P<0.05）。
浙江省新尘肺病病例逐年增加，尘肺病主要类型为矽肺，尘肺病病例分布与地区和企业有关，新尘肺病病例接触工龄相对较短。
