[Analysis of spatial-temporal distribution of pesticide poisoning in Quzhou, 2013-2017].

ABSTRACT

Objective: To analysis the epidemic and spatial characteristics of pesticide poisoning in Quzhou during 2013-2017, and to provide scientific basis for the prevention and control of influenza in Quzhou in the future. Methods: The incidence data of pesticide poisoning from January 1, 2013 to December 31, 2017 in Quzhou collected from China Information System For Disease Control And Prevention. The descriptive analysis conducted by using SPSS18.0 software, and the Sa T Scan 9.2 software was used to complete space-time scan. Finally, ArcMap10.2 software was used to visualize the results. Results: There were 1819 cases of pesticide poisoning in Quzhou from 2007 to 2016, among which 298 cases were reported for productive poisoning, the incidence peak was from August to September, the highest number of patients in productive poisoning was in the age group of 46-60 years old and over 61 years old, with 109 patients in each group, and the number of male patients was significantly higher than that of female (χ(2)=63.857, P<0.01) . 1521 cases of non-productive pesticide poisoning were reported, among which the proportion of suicide poisoning (57.65%) was far higher than that of accidental poisoning (28.97%) , the number of female suicide poisoning was higher than that of male (χ(2)=5.510, P=0.019) , the proportion of accidental poisoning was the highest in the ≤15 years age group (89.00%, 89/100) , furthermore the number of suicide poisoning was the highest in the ≥61 years age group (314) . The incidence of pesticide poisoning could be detected by temporal-spatial scanning statistics, the time clustering is from August to September, the spatial clustering is in Jiangshan city, there are consistent with the descriptive of pesticide poisoning. Conclusion: The pesticide poisoning in Quzhou is mainly caused by non-productive suicide poisoning, and the spatial clustering is in Jiangshan city. Relevant departments should carry out targeted prevention and control measures according to the different characteristics of pesticide poisoning in clustered and non-clustered areas.
