使用SPSS18.0统计软件对收集的1996—2015年宁夏自治区职业病诊断机构报告的煤工尘肺个案资料进行统计,并作描述性分析和趋势性检验,包括煤工尘肺新发病例的年度、地区、工业系统和工种分布,以及发病年龄、接尘工龄的变化趋势。结果显示,1996—2015年,宁夏累计报告煤工尘肺1172例,以壹期为主;2005年以前每年报告的煤工尘肺病例较少,2005年以后明显增多,2012年以后又逐步回落;新发煤工尘肺主要分布在石嘴山市和银川市,分别为949例(80.97%)和200例(17.06%);煤工尘肺主要集中在煤炭开采和洗选业,以主采煤工、主掘进工、纯采煤工、煤矿混合工和纯掘进工为前5位;发病年龄中位数为50.00岁,接尘工龄中位数为22.00年;2006—2015年间诊断的煤工尘肺发病年龄小于1996—2005年,而接尘工龄则无明显变化。建议建立多部门合作机制,从源头上控制尘肺病的发生。
Statistical data of collected pneumoconiosis pneumoconiosis cases reported by Ningxia Occupational Disease Diagnostic Agency from 1996 to 2015 were collected and analyzed by descriptive analysis and trend test, including the annual, regional, Distribution of industrial systems and types of work, as well as the age of onset, the trend of dust-aging. The results show that from 1996 to 2015, Ningxia has reported a total of 1172 coal worker’s pneumoconiosis cases, mainly in the first phase. Before 2005, there were fewer cases of coal worker’s pneumoconiosis reported each year before 2005, but obviously increased after 2005 and gradually dropped again after 2012. New The coal miners ’pneumoconiosis mainly distributed in Shizuishan City and Yinchuan City, which were 949 cases (80.97%) and 200 cases (17.06%) respectively. The coal workers’ pneumoconiosis mainly concentrated in the coal mining and washing industry, with main coal miners and main tunneling The median age of onset was 50.00 years old, the median age of dust pick-up was 22.00 years; the age of diagnosis of coal worker’s pneumoconiosis during 2006-2015 was less than From 1996 to 2005, there was no obvious change in the service life of dust. It is proposed to establish a multi-sectoral cooperation mechanism to control the occurrence of pneumoconiosis at the source.
