OBJECTIVETo explore the association between occupational stress and other socio-psychological factors and work-related unintentional injury in off-shore oil production.

METHODSA cross-sectional survey was conducted among 561 Chinese off-shore oil workers. They were inquired with a self-administered questionnaire involving in socio-demographic characteristics, occupational stress, type A behavior personnel, social support and coping style, and work-related unintentional injury in the past year.

RESULTSSeventy-six (13.5%) workers experienced work-related unintentional injury for once time or more in the past year. A total 141 number of person-times were counted including 18 person-times being serious injury, 26 person-times moderate, and 97 person-times light. After adjustment for age, educational level, marital status, duration of off-shore work and job title, logistic regression indicated that perceived stress from "management problem and relationship with others" were significantly associated with work-related unintentional injuries in the past year (OR = 1.33, 95% CI: 1.05-1.68; P < 0.05). Workers lack of emotional support from friends seemed to less reporting on work-related unintentional injuries (OR = 0.37, 95% CI: 0.22-0.63).

CONCLUSIONThe results implied emphasizing on that the training and guidance as well as better cooperation among the workers might reduce work-related unintentional injuries in off-shore oil industry.
