Study On The Spatial And Temporal Distribution Characteristics Of Poisonous Mushroom Poisoning And Its Correlation With Socioeconomic Development In Jiangxi Province,2016-2020

Objective:To grasp the basic situation of muscarinic poisoning in Jiangxi Province from2016 to 2020,to explore the spatial and temporal distribution characteristics of muscarinic poisoning in Jiangxi Province,and to analyze the correlation between muscarinic poisoning and socioeconomic development.To provide reference for the evaluation of the risk of poisoning by mushrooms and the development of prevention and control measures in various regions of Jiangxi Province.Methods:Descriptive analysis was used to master the basic situation of mushroom poisoning in Jiangxi Province from 2016 to 2020 The incidence of mushroom poisoning was smoothed by spatial empirical bayesian smoothing method The spatial distribution characteristics of mushroom poisoning in Jiangxi Province were studied by trend surface analysis and spatial autocorrelation analysis Factor analysis and multiple linear regression were used to analyze the relationship between toadstool poisoning and social economic development.Results:(1)From 2016 to 2020,there were a total of 283 incidents of mushroom poisoning in Jiangxi Province,with a total of 938 cases,of which 183 were hospitalized.268 poisoning incidents occurred in households,accounting for 94.7%.Mushroom poisoning incidents mainly occur in summer and autumn,with the peak number of cases occurring mainly in June and September.The clinical characteristics of poisoning patients mainly include nausea,vomiting,abdominal pain,diarrhea,and a few patients may experience other symptoms such as breathing difficulties and hallucinations.(2)The trend surface characteristics of mushroom poisoning incidence in Jiangxi Province were high in the northern region and low in the southern region,which were mainly concentrated in the northeastern region of Jiangxi.The positive residual boundary value L~+=0.29 and the negative residual boundary value L~-=-0.29,16 counties(cities and districts)were larger than the positive residual boundary value and 20 counties(cities and districts)were smaller than the negative residual boundary value.Among them,Du chang County and Lu shan City have anomalous peaks of residuals.(3)The spatial autocorrelation of mushroom poisoning in Jiangxi Province was demonstrated by spatial aggregation(Moran’s I>0).The"hot spots"were located in Ying tan and Xin yu counties(cities and districts),while the"cold spots"were mainly located in the south of Jiangxi Province.(4)Three principal components are extracted from the social and economic development:the Economic and educational development component,the proportion of the population aged 60 and over,and the expenditure component of the general public budget.Among them,the economic and educational development and the proportion of the population aged 60 and over have no significant impact on mushroom poisoning,while the general public budget expenditure has a significant impact on mushroom poisoning.Conclusion:(1)We have mastered the three distribution characteristics of mushroom poisoning in Jiangxi Province and the basic clinical characteristics of patients with mushroom poisoning.(2)The spatial and temporal distribution characteristics of poisonous mushroom poisoning in Jiangxi Province were explored.The seasonal characteristics of mushroom poisoning in Jiangxi Province are significant in time.Spatially,the overall trend is to show the trend characteristics of more in the middle and less in the north;spatial aggregation exists in local areas.(3)The correlation between muscarinic poisoning and socioeconomic development of each region in Jiangxi Province was analyzed.The general public budget expenditure component had an effect on muscarinic poisoning;the economic and educational development component and the population aged 60 and above component had no effect on muscarinic poisoning.
