Abstract

Background: Carpentry is one of the most important industries in Iran, where many people are employed. The aim of this study was to investigate spirometric indices and respiratory symptoms among carpentry, paint and office workers in wood factory in 2019. Materials and Methods: This is a cross-sectional case-control study. Population included of 100 people (70 exposed and 30 non-exposed). Demographic information of individuals was assessed by clinical questionnaire and pulmonary function tests including 1FEV, FVC, FEV1 / FVC in workers. Data were analyzed using one way ANOVA and Chi-Square Test. Results: The average of respirable wood dust for factory workers were 4.49 2 2.01 in terms of mg / m3, which was shown in comparison with the standard (1TLV :). Also, all respiratory symptoms including cough, sputum, shortness of breath, and wheezing were higher in the exposed group than in the non-exposed group. (P≤0/05) The highest and lowest percentages of people in the carpentry profession, in terms of testing spirometric indices with spirometry pattern were mildly restrictive (Mild) and severe, respectively. Conclusion: Exposure to wood dust as a factor determines the prevalence of symptoms of respiratory disorders and decreased lung capacity. Wood dust can reduce lung volumes and cause respiratory problems in wood industry workers. Keywords: Lung function, Respiratory symptoms, Spirometric, Wood dust.
