Study on the epidemic characteristics and trends of occupational chemical poisoning in Guangdong Province / 中国职业医学

ABSTRACT

OBJECTIVE: To analyze the epidemiological characteristics and predict epidemiological trends of occupational chemical poisoning,based on directly reported data during 2006-2015 in Guangdong Province. METHODS: The data of patients with occupational chemical poisoning reported from National Information Surveillance System for Occupational Disease and Occupational Health from 2006 to 2015 in Guangdong Province were collected. The epidemiological characteristics were retrospectively analyzed. The autoregressive integral moving average model( ARIMA model) was established and validated based on the number of the new onset cases and was used to predict the trends of occupational chemical poisoning from 2017 to 2020 in Guangdong Province. RESULTS: From 2006 to 2015,1 288 new cases of occupational chemical poisoning were reported in Guangdong Province,which accounted for 24. 4% of the total number of new cases of occupational diseases in the province( 5 283 cases). Among the new cases,the percentage of acute and chronic poisoning was 21. 7%( 279/1 288) and 78. 3%( 1 009/1 288). There was 74. 7%( 962/1 288) of organic solvent poisoning. Five kinds of new occupational chemical poisoning were found. Most of the new cases were male,accounting for 56. 7%( 729/1 288). They were mainly distributed and concentrated in Pearl River Delta Region,accounting for 95. 9%(1 235/1 288). Shenzhen,Dongguan and Guangzhou were the most three cities which had 425,325 and 209 cases respectively,all of them accounted for 74. 4%( 959/1 288). The new cases of poisoning mainly distributed in medium and small enterprises( 72. 0%),private economic enterprises( 50. 9%) and manufacturing industries(70. 5%). The number of occupational chemical poisoning diseases decreased first,and increased,and the proportion to the total number of occupational diseases in Guangdong Province showed a straight downward trend(P < 0. 01). The median age at diagnosis was 35 years old and the median work year at diagnosis was 2. 0 years,and both of them showed an increasing trend( P < 0. 01). CONCLUSION: Occupational chemical poisoning in Guangdong Province has certain characteristic of crowd aggregation and epidemic trends.
