An international research project led by ISglobal has linked exposure to biological dusts, gases, fumes and pesticides with a higher incidence of COPD.
In this study, published in Thorax, 3,343 participants from 12 countries were selected between 1991 and 1993, and followed-up 20 years later. The results showed that participants exposed to biological dust had a 60% higher risk of COPD compared with those unexposed, while in the case of those exposed to gases and fumes the risk was a 50% higher and in the ones exposed to pesticides the risk was a 120% higher. Overall, results showed that 21% of the 96 cases of COPD detected at follow-up were associated with these occupational exposures. "Previous studies had estimated that about 15% of COPD cases are attributable to workplace exposures. Our results strengthen this evidence base substantially", says Jan-Paul Zock, ISGlobal researcher and lead author of the study. "To our knowledge, this is the first study to demonstrate an effect of biological dust exposure on the incidence of COPD in a prospective fashion in a general population cohort", he adds. - Carlos Sierra/PRBB
