GUTIERREZ, Waldo et al. Characterization of pesticide exposures reported between 2006 and 2013 to a poison information center in Chile. Rev. méd. Chile [online]. 2015, vol.143, n.10, pp.1269-1276. ISSN 0034-9887.

Background: Pesticides are widely used to increase crop yields and vector control. However, both acute and chronic exposure have health consequences. There is paucity of information about the global occurrence of pesticide poisonings. Aim: To characterize the reports of pesticide exposures received by a University Poison Information Center. Material and Methods: All pesticide exposures reported in Chile between 2006 and 2013 were analyzed. A data-collection sheet provided by the International Programme on Chemical Safety of the World Health Organization, was used to collect information. Results: In the study period, 13,181 reports were analyzed. The main age groups exposed were preschoolers and adults. Sixty one percent of exposures occurred accidentally and 24.8% were suicide attempts. Exposures to acetylcholinesterase inhibitors was reported in 29.3% of cases, to superwarfarin rodenticides in 28.5% and to pyrethroids in 24.0%. An increased risk of suicide attempts with pesticides was observed among women, when compared with men (odds ratio: 1.5; 95% confidence intervals: 1.4-1.6; p < 0.001). The risk was higher among teenage girls. Conclusions: The amount of cases under acetyl cholinesterase inhibitor exposure, the most toxic pesticides currently in use should be highlighted. Workers should be educated and all cases should be reported to take actions aiming at reducing these events.
