Background:
Paraquat self-poisonings constitute a significant contributor to the global burden of suicide. Our aim was to evaluate the relationship between social and economic variables with the incidence of self-poisoning with Paraquat in the northeast of Colombia.
Methods:
Records of 154 cases of self-poisoning with Paraquat and several socio-economic variables of six regions of northeast of Colombia were analyzed.
Results:
Most of the cases were mestizos, farmworkers, between 20 and 29 years, with intentional exposure using the oral route. Multivariate analyses revealed significant associations among the incidence of self-poisoning with PQ with the ecological factors such as poverty greater than 30% (IRR 15.9 IC95% 5.56-44.72), land Gini index < 0.7 (IRR 7.11 IC95% 3.58-14.12), private health insurance < 40% (IRR 3.39 IC95% 1.30-8.82) and planted area > 10% (IRR 2.47 IC95% 1.60-3.80).
Conclusion:
There is a relationship between ecological factors and, as such, this study opens the way to further developments in the field.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
