Professions and Working Conditions Associated With Community-Acquired Pneumonia

Abstract Introduction Community-acquired pneumonia (CAP) is not considered a professional disease, and the effect of different occupations and working conditions on susceptibility to CAP is unknown. The aim of this study is to determine whether different jobs and certain working conditions are risk factors for CAP. Methodology Over a 1-year period, all radiologically confirmed cases of CAP ( n  = 1336) and age- and sex-matched controls ( n  = 1326) were enrolled in a population-based case–control study. A questionnaire on CAP risk factors, including work-related questions, was administered to all participants during an in-person interview. Results The bivariate analysis showed that office work is a protective factor against CAP, while building work, contact with dust and sudden changes of temperature in the workplace were risk factors for CAP. The occupational factor disappeared when the multivariate analysis was adjusted for working conditions. Contact with dust (previous month) and sudden changes of temperature (previous 3 months) were risk factors for CAP, irrespective of the number of years spent working in these conditions, suggesting reversibility. Conclusion Some recent working conditions such as exposure to dust and sudden changes of temperature in the workplace are risk factors for CAP. Both factors are reversible and preventable.
