Abstract:
Objective To analyze the distribution characteristics and development trends of pesticide poisoning in Hainan Province, 2014—2023, and to provide a scientific basis for formulating prevention and control measures for pesticide poisoning in Hainan Province. Methods The Occupational Diseases and Health Hazards Monitoring Information System, a module of the China Disease Prevention and Control Information System, was the primary data source of the study. A descriptive analysis was performed on time distribution, demographic characteristics, regional distribution, poisonous pesticide types, and development trends of pesticide poisoning in Hainan Province from 2014 to 2023. Results From 2014 to 2023, a total of 1 561 pesticide poisoning cases were reported in Hainan Province, with 68 deaths, resulting in an average annual incidence of 1.60/100 000 and an overall case fatality rate of 4.36%. The primary type of poisoning was non-occupational (1 227 cases, 78.60%). The high incidence of poisoning occurred in 2019 (210 cases, 13.45%), 2018 (209 cases, 13.39%), and 2016 (204 cases, 13.07%), mostly in the third quarter (440 cases, 28.19%). Occupational poisoning predominantly occurred from July to September, while non-occupational poisoning was more frequent in May, January, and August. The majority of poisoning cases were male (832 cases, 53.30%) and the standardized case ratio of male to female was 1.05∶1. The average age of cases was (42.10±19.81) years old, with high incidence rates in the 35-<45 age group (305 cases, 19.54%), 45-<55 age group (293 cases, 18.77%), and 25-<35 age group (285 cases, 18.26%). The highest case fatality rate was observed in the group aged 65-<75 years (6.84%). Regions with the highest incidence rates were Lingao County (103.68/100 000), Wuzhishan City (71.85/100 000), and Baoting Li and Miao Autonomous County (64.88/100 000). Herbicides (590 cases, 37.80%) and insecticides (582 cases, 37.28%) were the main species of pesticides that caused poisoning, and there was a significant difference in the distribution of pesticide species（χ2=129.023, P<0.05). The types of pesticides with the top three fatality rates were paraquat (16.15%), methamidophos (14.29%), and dichlorvos (12.50%). The time distribution of pesticide poisoning cases was uneven, with total cases, occupational and non-occupational cases all showing a linear development trend over the ten-year period (Z=5.027, 4.654, 3.241, all P<0.05). Conclusions Non-occupational pesticide poisoning is the major type of pesticide poisoning prevention and control in Hainan Province at present. It is recommended to take comprehensive measures including strengthening supervision of pesticide production and sales, promoting safety knowledge of pesticide use, and strengthening the construction of grassroots mental health through joint efforts of multiple departments to prevent the occurrence of pesticide poisoning.
