Influence of job burnout and sleep quality on working ability of oil workers / 中国职业医学

ABSTRACT

OBJECTIVE: To explore the current situation of job burnout, sleep quality and working ability and the association among them in oil workers. METHODS: A total of 2 086 oil workers from six oil field companies in a city of Xinjiang Uygur Autonomous Region were selected as the study subjects using a typical sampling method. The job burnout level, sleep quality and working ability were measured respectively by the Maslach Burnout Inventory-General Survey, Pittsburgh Sleep Quality Index and Work Ability Index Questionnaire. RESULTS: The average score of job burnout in the study subjects was(48.6±11.0), the median and the 25 th, 75 th percentile of sleep quality and working ability scores were 6.0(5.0, 8.0) and 39.0(36.0, 42.0) respectively. There was a negative correlation between job burnout and working ability, or sleep quality and working ability [spearman correlation coefficient(r_S) were-0.28 and-0.21, all P<0.01]. There was a positive correlation between job burnout and sleep quality(r_S=0.19, P<0.01). The structural equation model results showed that both job burnout and sleep quality had a direct effect on working ability of oil workers [normalized path coefficient(β) were-0.29 and-0.27, respectively, all P<0.01]. Job burnout could indirectly affect working ability through reducing sleep quality(β=-0.12, P<0.01). CONCLUSION: The higher the degree of job burnout and the poorer the sleep quality, the lower their working ability in oil workers. Oil workers with a higher degree of job burnout can lead to poorer sleep quality, which in turn leads to a decline in their working ability.
