[Analysis of acute pesticide poisoning in Ningbo city from 2011 to 2016].

Objective: To analyze the characteristics of acute pesticide poisoning in Ningbo, and to provide scientific basis for the prevention and control strategy. Methods: In February 2017, the pesticide poisoning report card of Ningbo from 2011 to 2016 was drawn from the China Disease Control and prevention information system. The data of the report card was organized by Excel and analyzed by SPSS19.0 software. Results: 2593 cases of acute pesticide poisoning were reported in Ningbo from 2011 to 2016, 125 deaths, and the case fatality rate was 4.82%. The productive pesticide poisoning and unproductive pesticide poisoning were 299 and 2294, respectively, the ratio was 1: 7.67. The case fatality rate were 0.33% and 5.41%, respectively. The difference was statistically significant (χ(2)=14.83, P<0.01). The productive Pesticide poisoning mainly occurred from July to September (55.85%) , the unproductive pesticides mainly occurred from April to June (30.64%) and July to September (30.34%). The seasonal distribution of the pesticide poisoning in the two groups was statistically significant (χ2=82.21, P<0.01). The productive pesticide poisoning in male (80.27%) was significantly higher than the proportion of unproductive pesticide poisoning (52.09%) , the differences in gender composition between the two types of pesticide poisoning was significant (χ2=84.97, P<0.01). The productive pesticide poisoning from 55 to 65 years old group was in the largest number (35.45%) , and the distribution of unproductive pesticide poisoning was uniform in each age group including 25 years old and above, the difference in age composition between two types of pesticide poisoning was statistically significant (χ2=177.84, P<0.01). All of the 10 counties of Ningbo had reports of pesticide poisoning. The counties with more reports were Ninghai county (18.28%) , Fenghua district (14.69%) and Yuyao (12.42%). The acute pesticide poisoning was mainly caused by pesticides and herbicides, mainly in organophosphorus (45.74%) and paraquat (16.81%) . Conclusions: At present, the pesticide poisoning in Ningbo is given priority to unproductive pesticide poisoning currently, seasonal distribution characteristics was obvious, and occurred both in different sex and age groups, suggesting that the relevant departments should carry out targeted health education, and strengthen the management of high toxic and highly toxic pesticides.目的： 分析宁波市急性农药中毒发病特征，为制定防控策略提供科学依据。 方法： 于2017年2月，从中国疾病预防控制信息系统导出宁波市2011至2016年农药中毒报告卡，对报告卡数据资料进行整理，用χ(2)检验比较各组中毒构成比或病死率，用线性回归分析农药中毒的年度变化趋势。使用SPSS 19.0软件对数据进行统计分析。 结果： 宁波市2011至2016年报告急性农药中毒2 593例，死亡125例，病死率4.82%。生产性农药中毒和非生产性农药中毒分别为299例和2 294例；病死率分别为0.33%和5.41%，差异有统计学意义（χ(2)=14.83，P<0.01）。生产性农药中毒7~9月（55.85%）高发，非生产性中毒高发于4~6月（30.64%）和7~9月（30.34%），两类农药中毒季节构成比的差异有统计学意义（χ(2)=82.21，P<0.01）。生产性农药中毒男性（80.27%）占比明显高于非生产性农药中毒（52.09%），两类农药中毒性别构成比的差异有统计学意义（χ(2)=84.97，P<0.01）；生产性农药中毒55至65岁年龄组人数最多（35.45%），非生产性农药中毒25岁及以上各年龄组人数分布较均匀，两类农药中毒年龄构成比的差异具有统计学意义（χ(2)=177.84，P<0.01）。宁波市10个县区均有农药中毒病例报告，报告较多的县区有宁海县（18.28%）、奉化区（14.69%）和余姚市（12.42%）。导致急性农药中毒主要有杀虫剂和除草剂，其中以有机磷类（45.74%）和百草枯（16.81%）为主。 结论： 当前宁波市急性农药中毒以非生产性农药中毒为主，季节分布特征明显，不同性别及各年龄段均有发生，提示相关部门应开展针对性健康宣教工作，同时加强对高毒、剧毒农药的管理。.
