Study of Ventilatory Functions Test in Construction Workers

Introduction: The aim of the study was to determine ventilatory functions tests in construction workers. Workers engaged in building and construction workplace are at high risk of developing impaired lung functions due to exposure of high level of dust generated at the construction sites. Material and methods: The lung function was studied in 30 male construction workers and 30 male control subjects. All the participants were non smokers. The subjects were matched for age, height and weight. The pulmonary function test was performed by using a computerised spirometer and results were compared by student’s unpaired t test. Results: The results of present study showed a significant decrease in mean value of PEFR (p value<0.05), FVC, FEV1 (for both p<0.00001), and FEF25-75% (p<0.0001). Conclusion: The results of this study shows that occupational exposure to inorganic and organic dust, cement particles affects ventilatory functions. This study indicates that construction workers are at high risk of developing mixed pattern of obstructive and /or restrictive ventilatory impairment.
