0160/2025 - Eventos tóxicos em adolescentes no período de 2015 a 2022: características e fatores associados a tentativas de suicídio Toxic events in adolescents from 2015 to 2022: characteristics and factors associated with suicide attempts
O objetivo foi analisar os eventos tóxicos em adolescentes e se os fatores sociodemográficos, a forma de exposição, a classe do agente tóxico e o período pré e pandemia estão associados às tentativas de suicídio. Estudo transversal com dados secundários de adolescentes expostos a agentes tóxicos entre 2015 e 2022, atendidos no Centro de Informação e Assistência Toxicológica no Ceará. Foram estimadas as razões de prevalências e seus respectivos IC 95%, utilizando a regressão de Poisson com variância robusta entre as variáveis explicativas e a tentativa de suicídio. Dos 703 casos de intoxicação em adolescentes, 69,6% (IC95% 66,0-72,8) ocorreram em mulheres, 77,6% (IC95% 74,4–80,7) foram tentativas de suicídio. Em relação aos agentes tóxicos utilizados, 63,9% utilizaram medicamentos e 17,4% praguicidas, com 44,1% destes casos envolvendo um inseticida de uso ilegal no Brasil. Na análise multivariada, estar no período pandêmico, ser mulher, o incremento da idade, estar em casa, utilizar medicamentos e praguicidas, e o uso associado de dois ou mais agentes permaneceram associados a maior prevalência de tentativa de suicídio. Os achados destacam a necessidade de ações preventivas focadas no ambiente doméstico, no controle de substâncias tóxicas e na proteção de adolescentes vulneráveis como mulheres.

Abstract:
The objective was to analyze toxic events in adolescents and determine if sociodemographic factors, the mode of exposure, the toxic agent, and the pre- and pandemic periods are associated with suicide attempts. A cross-sectional study was conducted using secondary data from adolescents exposed to toxic agents between 2015 and 2022, treated at the Brazilian Poison Control Center in Ceará. Prevalence ratios and their respective 95% CI were estimated using Poisson regression with robust variance between the explicative variables and suicide attempt. Out of 703 cases of poisoning in adolescents, 69.6% (95% CI 66.0-72.8) occurred in females, and 77.6% (95% CI 74.4–80.7) were suicide attempts. Regarding the toxic agents used, 63.9% of adolescents used drugs and 17.4% used pesticides, with 44.1% of these cases involving an insecticide illegally used in Brazil. In the multivariate analysis, being in the pandemic period, being female, increasing age, being at home, using drugs and pesticides, and the combined use of two or more agents remained associated with a higher prevalence of suicide attempts. The findings highlight the need for preventive actions focused on the domestic environment, the control of toxic substances, and the protection of vulnerable adolescents, particularly females.

Resumo (abstract):
The objective was to analyze toxic events in adolescents and determine if sociodemographic factors, the mode of exposure, the toxic agent, and the pre- and pandemic periods are associated with suicide attempts. A cross-sectional study was conducted using secondary data from adolescents exposed to toxic agents between 2015 and 2022, treated at the Brazilian Poison Control Center in Ceará. Prevalence ratios and their respective 95% CI were estimated using Poisson regression with robust variance between the explicative variables and suicide attempt. Out of 703 cases of poisoning in adolescents, 69.6% (95% CI 66.0-72.8) occurred in females, and 77.6% (95% CI 74.4–80.7) were suicide attempts. Regarding the toxic agents used, 63.9% of adolescents used drugs and 17.4% used pesticides, with 44.1% of these cases involving an insecticide illegally used in Brazil. In the multivariate analysis, being in the pandemic period, being female, increasing age, being at home, using drugs and pesticides, and the combined use of two or more agents remained associated with a higher prevalence of suicide attempts. The findings highlight the need for preventive actions focused on the domestic environment, the control of toxic substances, and the protection of vulnerable adolescents, particularly females.
