Abstract

Purpose: This study aimed to identify distinct patterns of pesticide poisoning in Brazil through the cluster analysis of epidemiological data from 2011 to 2019.

Methods: A cross-sectional analysis of 49,233 confirmed pesticide poisoning cases was conducted using multiple correspondence analysis and hierarchical clustering. Data from the Brazilian Notifiable Diseases Information System were analyzed by region, demographics, and exposure types.

Results: Three distinct clusters were identified. Cluster 1 was characterized by severe cases, predominantly involving suicide attempts (~90%), required treatment (99.1%) and fatality rates (93.2% of all cases). Exposures were mostly domestic and occurred via ingestion, with a strong prevalence in the Northeast. Cluster 2 consisted mainly of pediatric cases, marked by accidental and acute domestic exposures, and showed minimal representation in the Southeast and South regions. Cluster 3 had a male predominance (80.1%) and was strongly associated with occupational and chronic exposures, involving cutaneous and respiratory routes, and was most prevalent in the Central-West.

Conclusion: The study reveals significant regional and demographic disparities in pesticide poisoning across Brazil. These findings underscore the urgent need for targeted public health interventions and stricter pesticide regulations to address regional vulnerabilities and mitigate pesticide-related harm.

鉴定巴西不同的农药中毒模式：流行病学数据的横断面聚类分析。

目的：本研究旨在通过对2011 - 2019年流行病学数据的聚类分析，确定巴西农药中毒的不同模式。方法：采用多重对应分析法和分层聚类法对49233例农药中毒确诊病例进行横断面分析。来自巴西法定疾病信息系统的数据按地区、人口统计和暴露类型进行分析。结果：鉴定出三个不同的簇。聚类1以重症病例为特征，主要涉及自杀企图（约90%）、需要治疗（99.1%）和死亡率（占所有病例的93.2%）。暴露主要发生在国内，并通过食入发生，在东北地区发病率很高。聚类2主要由儿科病例组成，以意外和急性家庭暴露为特征，在东南部和南部地区的代表性最小。聚类3男性占主导地位（80.1%），与职业性和慢性暴露密切相关，涉及皮肤和呼吸途径，在中西部地区最为普遍。结论：该研究揭示了巴西各地农药中毒的显著区域和人口差异。这些研究结果强调，迫切需要有针对性的公共卫生干预措施和更严格的农药法规，以解决区域脆弱性问题并减轻与农药有关的危害。

期刊介绍： International Archives of Occupational and Environmental Health publishes Editorials, Review Articles, Original Articles, and Letters to the Editor. It welcomes any manuscripts dealing with occupational or ambient environmental problems, with a special interest in research at the interface of occupational health and clinical medicine. The scope ranges from Biological Monitoring to Dermatology, from Fibers and Dust to Human Toxicology, from Nanomaterials and Ultra-fine Dust to Night- and Shift Work, from Psycho-mental Distress and Burnout to Vibrations. A complete list of topics can be found on the right-hand side under For authors and editors. In addition, all papers should be based on present-day standards and relate to: -Clinical and epidemiological studies on morbidity and mortality -Clinical epidemiological studies on the parameters relevant to the estimation of health risks -Human experimental studies on environmental health effects. Animal experiments are only acceptable if relevant to pathogenic aspects. -Methods for studying the topics mentioned above.
