Accumulated exposure of respirable dust as a predictor of respiratory disease

Project: Research Project

Project Details


In order to establish the risk of developing non-malignant respiratory diseases, specifically functional alterations, from accumulated exposure to respirable dust - and in the workers of an open-pit mining company in Colombia, this retrospective cohort study was structured in the workers of an open-pit mining company in Colombia. A total of 566 workers were registered in 29 Similar Exposure Groups (GES). The calculation of the accumulated dose was made considering the exposure medians for each Ges and the exposure time of each worker. And later the risk was estimated using a regression of poisson with robust variance.
Los resultados más importantes del estudio muestran la exposición acumulada en niveles inferiores a los reportados en la literatura, sin embargo se encuentra un riesgo ligeramente elevado, IRR 1.000124 (IC95% 1 - 1.000248) en los expuestos, estimando que por cada unidad de medición de la exposición acumulada que se incremente, el riesgo de que aparezca una alteración respiratoria funcional se incrementa en 1.000124 veces entre los trabajadores expuestos y los no expuestos.
