A study on the five-year change trend in pulmonary function of workers in tile and ceramic industry
Introduction: Among the pollutants present in the ceramic and tile industry, silica dust is particularly important, and many studies have investigated the effect of this material on the respiratory system. Many occupational exposures may result in a decrease in spirometric parameters. Materials and...

| description | Introduction: Among the pollutants present in the ceramic and tile industry, silica dust is particularly important, and many studies have investigated the effect of this material on the respiratory system. Many occupational exposures may result in a decrease in spirometric parameters.
Materials and Methods: In the present study, totally, 120 male workers and employees of the factory, who had work experience of over 5 years and were not changed during the study, were included. Demographic information, including age, height, weight, work experience, smoking status and spirometric indices, were extracted from the medical records of the workers from different groups for 5 consecutive years. All spirometry tests were performed using the FUKUDA ST 300 digital spirometer (Italy) calibrated once a year. The generalized Estimation Equation (GEE) method was used to study the trend of changes in each of the spirometric indices more accurately. Research related data were analyzed using SPSS software version 23.
Results: The trend of changes was only significant for the FEV1 / FVC and FEF indices; for other indexes, the trend of changes was only observed in some years. The trend of changes was not significant for the FEV1 index, but smoking had a significant effect on the changes in this index. So, the level of this index was lower for cigarette smokers.
Conclusion: In this study, a clear downward trend was not found in the spirometric indices over 5 years, and only the FEF1 / FVC and FEF 2575% indices markedly were reduced in some occupational units, but due to the decline in some indices as well as proving the bad effect of Silica dust and other compounds on the respiratory system, there was an urgent need to implement management and engineering controls and protect the workers in the workplaces |
