Study Title:

[Effects of occupational stress factors on the function of thyroid and liver among petroleum refining and petrochemical workers]

Study Abstract

Objective: To investigate the association between occupational stress factors and the level of thyroid function and liver function in petroleum refining and petrochemical workers.
Methods: A total of 353 petroleum refining workers were investigated by occupational stress indicator question-naire (OSI-R) , and their level of thyroid and liver function were measured.
Results: With the incre-ase of task control, decision control, environmental control, resource control and technology utilization score, the TT(4) concentration level decreased (P<0.05) . The TT(4) concentration level increased with the increase of the quantiontive load, load changes, job hazards, job prospects, promation opportunities and participaction decision rating (P<0.05) . The total protein concentration level decreased with the increase of task control, decision control, environmental control, resource control, quantitative load, load change, promotion opportunity and participation decision value (P<0.05) , increased with the use degree of technology, work risk, job monotonous, work prospects score rised (P<0.05) . And there were statistically significant differences in the job requirements and job control scores between the low, middle and high levels of occupational factors (P<0.05) .
Conclusion: Occupational stress factors of petroleum refining workers have certain influence on the level of thyroid and liver function index.
