Lung Function Comparison by the Technique of Spirometry Between Different Working Groups of Pakistan: A Cross-Sectional Survey Based Study
Objective: To evaluate the comparison of lung function among carpenters, stone quarry workers, and coal miners.
Methods: This was a cross-sectional survey-based study. The study was conducted in two cities, Quetta and Mach, Balochistan province, Pakistan. The validated survey form and spirometer were utilized. A total number of 300 men workers; carpenters, stone quarry workers and coal miners, 15 years and above were considered. The parameters of spirometer; Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), Peak Expiratory Flow Rate (PEFR) and Forced Vital Capacity ratio (FEV1/FVC) were evaluated. The information was exactly evaluated by utilizing Microsoft Excel-2013 and SPSS-22.
Results: The FVC mean value± in carpenters were 80.73±16.26, followed by FEV1 (61.74±12.43), PEFR (75.23±19.10), and FEV1/FVC mean value± (77.90±15.77). The FVC mean value± in stone quarry workers were (84.58±12.37), FEV1 (62.46±11.76), PEFR (70.02±17.12), and FEV1/FVC (73.90±10.45). The FVC mean value± in coal miners were (84.36±08.35), followed by FEV1 (60.79±08.77), PEFR (74.44±13.01), and FEV1/FVC 72.13±08.14.
Conclusions: The findings indicate that the lung function of all working groups was adversely affected and disclosed restrictive lung disease. The lung function of coal miners was more affected than the carpenters and stone quarry workers.
