[Relationship between occupational stress and working ability of workers in a petroleum processing enterprise in high altitude area].

摘要:

Objective: To investigate the relationship between occupational stress and working ability of workers in a petroleum processing enterprise in a high altitude area. Methods: A total of 728 workers in a petroleum processing enterprise at an altitude of 2850 m were subjected to a survey using Occupational Stress Inventory (OSI) , Work Ability Index (WAI) Scale, Occupational Role Questionnaire (ORQ) , Personal Strain Questionnaire (PSQ) , and Personal Resource Questionnaire (PRQ) from May 2014 to August 2016. Results: Of the 728 workers, 55 (7.6%) had a poor working ability, moderate in 262 (35.9%) , and good in 411 (56.5%). There were significant differences in WAI between the workers with different types of work, sexes, ages, and working years (P<0.05). There was a significant difference in WAI between different occupational stress groups (P<0.05). WAI was negatively correlated with ORQ score and PSQ score (r(s)=-0.387, P<0.05; r(s)=-0.467, P<0.05) and positively correlated with PRQ score (r(s)=0.343, P<0.05). The multiple linear regression analysis showed that high ORQ score and PSQ score were the inhibitory factors for high WAI (B=-0.058; B=-0.082) and high PRQ score was a contributing factor for high WAI (B=0.029) . Conclusion: Occupational stress is an influencing factor for the working ability of workers in the petroleum processing enterprise in the high altitude area. Hypoxia in high altitude area may further reduce the working ability. In order to reduce occupational stress and improve work ability, it should be considered to strengthen skills training, improve the working environment, and pay attention to mental health.
