Comparison of Lung Function in Different Temperaments of Workers

 Pulmonary diseases are one of the most common occupational diseases caused by many factors such as lifestyle, work environment conditions, rate and severity of exposure. In addition to these factors, individual of physical conditions also plays an important role in the initiate, spread or worsening of these diseases. One way to measure, the innate ability of individuals to deal with occupational pathogens is to determine temperament. It is possible to predict the degree of their inherent vulnerability to workplace pathogens by determining workers' temperaments prior to job allocation, and thus reduced the severity of occupational injuries, Lung injuries are one of the most important occupational injuries in cement factories. The aim of this study was to compare the pulmonary function in different temperaments of cement factory workers.

 This was a cross-sectional descriptive-comparative study. It done with the participation of 92 qualified workers of Mehriz Cement Factory. In addition to determining workers' temperaments, pulmonary function indices including vital capacity (VC), forced vital capacity (FVC) and forced expiratory flow of 25-75% (FEF 25-75%) also evaluated. ANOVA and Tukey tests used for statistical analysis of data.

Ethical Considerations:

 The Ethics Committee of Payam Noor University has approved the present study with code IR.PNU.REC.1398.116.

 The results of statistical tests show that all variables (VC, FEV1 and FVC) except EF 25-75% were significant. Pulmonary indices of VC, FEV1 and FVC in warm temperaments were significantly higher than cold temperaments.

 According to the results, cold temperaments are more likely to have respiratory and lung problems than hot temperaments. Therefore, more care must take in employing cold temperaments workers.
