ABSTRACT
OBJECTIVE: To analyze the relationship between the quality of life and occupational stress among workers in a chemical industry base. METHODS: By a judgmental sampling method,the quality of life and occupational stress of 517 workers in a chemical plant were evaluated using the World Health Organization Quality of Life-BREF and the Occupational Stress Inventory-Revised. RESULTS: The median( P0-P100) of the scores of total quality of life was 51. 52(24. 62-74. 29)in the 517 chemical plant workers. The score of occupational role questionnaire( ORQ) of the workers was lower than that of the production laborer group [( 161. 40 ± 24. 99) vs( 183. 36 ± 22. 02),P < 0. 01]. The scores of personal strain questionnaire( PSQ) and personal resources questionnaire( PRQ) were higher than those of production laborer group[(100. 18 ± 20. 69) vs(97. 47 ± 13. 77),(131. 74 ± 17. 93) vs(128. 86 ± 18. 45),P < 0. 01]. The quality of life of the chemical plant workers who got higher scores in ORQ and PSQ were poorer than those who got lower scores in ORQ and PSQ( P < 0. 01). The quality of life of the chemical plant workers who got higher scores in PRQ were better than those who got lower scores in PRQ( P < 0. 01). The scores of total quality of life were negatively correlated with the scores of ORQ and PSQ( P < 0. 01),and positively correlated with the scores of PRQ( P < 0. 01). The key factors effected quality of life of chemical plant workers included personal strain,personal resources,occupational role,sleep time and injury on-the-job( P < 0. 05). CONCLUSION: The occupational stress of chemical plant workers may influence their quality of life. Reducing the occupational role and personal stress and increasing personal resources of chemical plant workers could improve their quality of life.
