Objective:
To study the effects p-phenylenediamine (PPD) on lung function and health-related quality of life of occupational exposed workers.
Methods:
This study was based on data from a company that produce hair dye containing PPD in China. Workers who exposed to PPD were selected as the study group, and workers un-exposed to PPD were selected as the control group. Questionnaires on health-related quality of life of workers using the 36-item Short Form Health Survey (SF-36) . Occupational health examination assessment results were tested in Taizhou Cancer Hospital. The lung function test includes forced vital capacity (FVC) , forced expiratory volume in one second (FEV1.0) , and ratio of FEV1.0 to FVC (FEV1.0/FVC) .
Results:
The difference in systolic blood pressure between the PPD exposed group and the control group was statistically significant (P<0.05) . FVC, FEV1.0, and FEV1.0/FVC of the lung function indexes in the exposed group were lower than those in the control group (P<0.05) . In the health-related quality of life, body pain (P=0.002) , general health (P=0.029) , vitality (P=0.038) , and mental health (P=0.003) were lower in the exposed group than in the control group.
Conclusion
Occupational exposed to PPD may induce hazard to the workers’lung function and may cause detrimental effect on workers’ health-related quality of life.
