La exposición ocupacional a sustancias capaces de desencadenar asma afectan a la gravedad de la enfermedad, según un estudio francés publicado en el "American Journal of Respiratory and Critical Care Medicine".
Investigaciones anteriores han mostrado que la exposición a tales sustancias constituye un factor de riego, pero no se sabía con certeza si incrementaba la gravedad.
Los autores analizaron datos de 148 adultos asmáticos y de 228 controles. Demuestran que la exposición a sustancias irritantes causantes de asma incrementa también la gravedad de la enfermedad entre 3,7 y 7,5 veces.
