Acute pesticide poisoning: Comparison of epidemiological characteristics between the rural and urban population

Objective: To analyze the behavior of pesticide poisoning associated with lethality in rural and urban populations in Colombia from 2007 to 2017. Methodology: Retrospective observational study that included a descriptive cross-sectional study and an ecological design that analyzed aggregate measures of morbidity, mortality, and risk attributable to the population in rural and urban areas. In the cross-sectional study, the relative risk was estimated to measure the factors associated with lethality among intoxications using Poisson regression with logarithmic function. For the time series, the trends were established with simple linear regression, and the seasonal decomposition was performed using the multiplicative model. Autocorrelations were tested using the Box-Ljung statistic. Results: Between 2007-2017; 89 490 cases were reported. The Morbidity due to poisoning showed a higher proportion in the rural population 36.03 cases per 100 000; this indicator was three times higher than in urban areas (12.33 cases per 100 000). The mortality rates in rural and urban areas were 1.00 and 0.13 cases per 100 000, respectively. The relative risk of fatality in case of intoxication was associated with the intention of suicide in the rural population Relative Risk (RR): 5.9 (95% CI: 5.0-6.9). Conclusion: A higher proportion of lethality associated with these events occurred in populations living in rural areas and reporting cases of suicidal intent. In addition, morbidity and mortality due to pesticide poisoning had the highest proportion in rural areas and a growing trend over time. Objetivo: Analisar o comportamento das intoxicações por pesticidas associadas com letalidade em população rural e urbana na Colômbia desde 2007 até 2017. Metodologia: Estudo observacional retrospectivo que incluiu um estudo descritivo transversal e um planejamento ecológico que analisou medidas agregadas de morbilidade, mortalidade e risco atribuíveis à população em áreas rurais e urbanas. No estudo transversal estimou-se o risco relativo para medir os fatores associados à letalidade entre as intoxicações por meio do uso da regressão de Poisson com função logarítmica. Para as séries temporais, foram estabelecidas as tendências com regressão linear simples, e realizou-se a decomposição sazonal por meio do modelo multiplicativo. As autocorrelações foram comprovadas por meio do estatístico de Box-Ljung. Resultados: Entre 2007-2017 foram reportados 89490 casos. A morbilidade por intoxicação
