Background Pesticide poisoning is not only a common acute poisoning, but also an indispensable public health problem. It is important to describe and analyze the epidemic characteristics and trends of pesticide poisoning for its prevention and control.
Objective To understand the epidemiological characteristics and trends of pesticide poisoning in Jiaxing from 2008 to 2020, and provide a basis for making effective intervention measures.
Methods The relevant information of pesticide poisoning cases in Jiaxing from 2008 to 2020 was collected through the Occupational Disease and Occupational Health Information Monitoring System of the China Disease Prevention and Control Information System, and the demographic information was obtained from the statistical yearbook of Jiaxing. Joinpoint regression models were used to analyze trends in overall, gender, age, season, type of poisoning, and type of pesticide among poisoned individuals.
Results A total of 3109 cases of pesticide poisoning were reported in Jiaxing City from 2008 to 2020. The overall pesticide poisoning incidence trended downward from 2008 to 2014, with an annual percent change (APC) of −9.0% (95%CI: −16.6%-−0.7%). The female pesticide poisoning incidence trended downward from 2008 to 2015, with an APC of −8.6% (95%CI: −13.9%-−2.9%). The 18-34 age group showed a decreasing trend of pesticide poisoning incidence from 2008 to 2015, with an APC of −11.0% (95%Cl: −17.4%-4.3%), and an increasing trend from 2015 to 2020, with an APC of 18.5% (95%Cl: 4.7%-34.0%). The >60 age group showed a decreasing trend of pesticide poisoning incidence from 2008 to 2014, with an APC of -12.9% (95%Cl: −20.4%-−4.7%). The second quarter showed an increasing trend of pesticide poisoning incidence from 2010 to 2020, with an APC of 4.4% (95%CI: 0.3%-8.5%); the third quarter showed a decreasing trend, with an APC of −4.9% (95%CI: −8.6%-−1.1%); the fourth quarter showed an increasing trend from 2015 to 2020, with an APC of 17.8% (95%CI: 4.4%-33.0%). Productive poisoning showed a decreasing trend, with an APC of −11.1% (95%CI: −16.2%-−5.7%); self-poisoning showed a decreasing trend from 2008 to 2014, with an APC of -9.5% (95%CI: −17.4%-−0.7%), and an increasing trend from 2014 to 2020, with an APC of 10.2% (95%CI: 0.5%-20.8%). The incidences of poisoning by herbicides, fungicides, and mixed formulations all showed an increasing trend from 2008 through 2020, with an APC of 8.6% (95%CI: 5.8%-11.5%), 9.1% (95%CI: 0.3%-18.7%), and 193.3% (95%CI: 11.6%-671.0%), respectively; the incidence of poisoning by other types of pesticides showed a decreasing trend from 2008 to 2020, with an APC of −14.1% (95%CI: −23.7%-−3.2%).
Conclusion The overall reported pesticide poisoning incidents in Jiaxing City present a decline then a rise in 2008 to 2020. Relevant departments should take timely measures to prevent and reduce the occurrence of pesticide poisoning according to the changing characteristics and occurrence trends of local pesticide poisonings.
