Occupational Exposure to Inhalable Agents Is Associated With Reduced Work Ability: A Prospective Cohort Study in Norway.

Abstract

This study aimed to assess Work Ability Score (WAS) in 2018 based on self-reported data regarding inhalable occupational exposure and data from a Northern European Job-Exposure Matrix recorded in 2013. During the 5-year follow-up period of this population-based study, 4423 participants completed a postal questionnaire comprising self-reported questions regarding occupational exposure, work history, and WAS. Ever, weekly, and daily exposure to vapors, gas, dust, and fumes in the last 5 years in 2013 was associated with reduced WAS in 2018. The Northern European Job-Exposure Matrix data showed that exposure to irritants, wood and paper dust, and mixed agricultural agents was associated with reduced WAS. Exposure to several occupational inhalable substances is associated with reduced work ability. We recommend reducing inhalable occupational exposure to prevent reduced work ability.
