2013-2022年浙江省硅肺发病时空分析

Spatial-temporal analysis of silicosis incidence in Zhejiang Province from 2013 to 2022

目的 分析浙江省硅肺发病重心和空间聚集性,为完善硅肺防控措施提供参考。方法 通过国家职业病及健康危害因素监测信息系统,收集2013-2022年浙江省硅肺病例资料,采用重心迁移和空间自相关分析浙江省硅肺发病时空特征。结果 2013-2022年浙江省累积报告硅肺病例2 902例,2013年、2019年和2014年报告发病数居前三位,分别为545、373和372例,占18.78%、12.85%和12.82%。病例以男性为主,2 874例占99.04%;职业以矿山开采及相关行业为主,1 463例占50.41%。2013年发病重心在嵊州市;2014-2018年发病重心向西南方向迁移至东阳市和义乌市;2019-2020年发病重心向东南方向迁移至仙居县和天台县;2021-2022年发病重心向西迁移至磐安县和仙居县。2014年、2016年和2021年硅肺发病具有空间自相关性(Moran's I值均>0,均P<0.05);高-高聚集区主要集中在宁波市、衢州市、温州市和台州市。结论 2013-2022年浙江省硅肺发病重心整体迁移幅度较小,主要在中部地区;高-高聚集区由宁波市和衢州市迁移至台州市。

Objective To investigate the gravity center and spatial clustering of silicosis in Zhejiang Province,so as to provide the reference for improving silicosis prevention and control measures.Methods Data on cases of silicosis in Zhejiang Province from 2013 to 2022 was collected from the National Occupational Disease and Health Risk Factors Monitoring Information System.The spatial and temporal characteristics of silicosis incidence in Zhejiang Province were analyzed using the gravity center migration and spatial autocorrelation analysis.Results Totally 2902 silicosis cases were reported in Zhejiang Province from 2013 to 2022.The reported cases in 2013,2019 and 2014 ranked the top three,with 545(18.78%),373(12.85%)and 372(12.82%)cases,respectively.The silicosis cases were predominantly males,accounting for 99.04%(2874 cases).The main occupation was mining and related industries,accounting for 50.41%(1463 cases).Gravity migration analysis showed that the gravity center of silicosis incidence was in Shengzhou City in 2013;from 2014 to 2018,it migrated to the southwest,and was located in Dongyang City and Yiwu City;from 2019 to 2020,it migrated to the southeast,and was located in Xianju County and Tiantai County;then from 2021 to 2022,it migrated to the west,and was located in Pan'an County and Xianju County.Spatial autocorrelation analysis showed that there was spatial correlation of silicosis incidence in 2014,2016,and 2021(all Moran's I>0,all P<0.05).Ningbo City,Quzhou City,Wenzhou City and Taizhou City were high-high clustering sites.Conclusions The gravity center of silicosis incidence in Zhejiang Province from 2013 to 2022 had a slight migration,and mainly gathered in the central regions.The high-high clustering sites were migrated from Ningbo City and Quzhou City to Taizhou City.
