After a questionnaire, we when through a clinical examination and performed arespiratory test with a manual portable spirometer. Our data were entered and analyzed using SPSS Version 22.0for Windows.Results: Respectively Carpenters vs unexposed: Smokers: 23.7%vs16.4%, p=NS; Alcohol consumption: 78.4%;vs 73.8%. Prevalence of symptoms: 51% vs26.2%, p<0.001. Lung function impairments: 24.2 %vs16.4%; Increasingage (P=0.007), smoking status, (P=0.013), length of stay in the job greater than or equal to 21 years (P=0.009) wereassociated to function impairment in univariate analysis. In a logistic regression age was associated to lung functiontest impairment: [OR=1.037 (CI 1.000 to 1.070) p=0.006)].Conclusion: Carpenters have higher function impairment that unexposed subjects. Smoking is associated withrespiratory symptoms among carpenters. Age of increases their risk of function impairments. Carpenters need to beincluded in health at work surveillance system.
