Fundamento

La explotación de pizarras constituye un riesgo para desarrollar silicosis; es una industria en auge e implica a un creciente número de trabajadores. No se conocen las repercusiones sobre su salud respiratoria.

Sujetos y método

Estudio transversal en trabajadores en activo. Se valoraron las alteraciones radiológicas y funcionales, y su relación con los factores de riesgo.

Resultados

Se encontró una prevalencia de neumoconiosis del 2,1%. El valor del volumenespiratorio máximo en 1 s (VEMS) se relacionaba significativamente con el tabaquismo y con la existencia de nodulación de profusión 1/0 o mayor; estos factores de riesgo, aplicada una regresión múltiple, actúan de forma independiente.

Conclusiones

La industria de pizarras supone un riesgo de neumoconiosis y otras alteraciones respiratorias.
