Assessment Of Lung Function Among the Workers in Plywood Industries

Abstract

This study aimed to assess the lung function and respiratory health of workers in the plywood industry, with a focus on the impact of workplace exposure to dust and fumes, smoking habits, and employment duration. A cross-sectional study was conducted on 51 exposed plywood workers and 23 age-matched controls. Lung function tests, including Forced Vital Capacity (FVC), Forced Expiratory Volume (FEV1), and Maximum Voluntary Ventilation (MVV), were performed. In addition, respiratory symptoms were recorded using a standardized questionnaire. Statistical analysis included t-tests and regression analysis to assess the relationship between lung function parameters and factors such as age, smoking, and work duration.The results revealed a significantly higher prevalence of respiratory symptoms, including cough, phlegm, and nasal issues, among plywood workers compared to the controls (p < 0.05). Exposed workers exhibited significantly lower lung function values (FVC, FEV1, and MVV) than controls, with a strong negative correlation between lung function and both age and smoking duration. A regression model indicated that FVC could be predicted with a high degree of accuracy based on age and smoking duration (R² = 0.73).The study highlights the detrimental impact of exposure to wood dust and fumes in the plywood industry on workers' respiratory health. Smoking exacerbates the effects, leading to significantly reduced lung function. The lack of protective equipment and preventive measures at the workplace increases the risk of respiratory disorders. The study recommends the adoption of protective gear, worker education, and stricter enforcement of occupational health regulations to minimize these health risks.
