[Factors of occupational stress on the working ability of petroleum workers]

Abstract

The relationship between occupational stress and working ability and their influence factors have been studied. 1230 oil workers in 122 work types of oil industry were selected and an occupational stress questionnaire (OSQ) was filled. The working ability index (WAI) in the female was significantly higher than that in the male (P < 0.0001). The working ability of petroleum workers became lower with the increasing of age, the duration of working time and stress levels (P < 0.001). The correlation on the labor load, adverse factors in the working environment and WAI was negative. It was concluded that the occupational stress could decrease the working ability of petroleum workers.
