Objective To assess the condition of occupational stress and related impact factors among medical staff.
Methods The job content questionnaire (JCQ) and the effort-reward imbalance questionnaire (ERI) were distributed to 1 200 medical staffs by random sampling, and 1 128 questionnaires were collected.
Results High level of occupational stress was reported by 916 medical staffs (81.2%) in JCQ and 262 (23.2%) in ERI. According to the results of JCQ, higher occupational stress was found in the staffs reporting family monthly income per capita <1 000 Yuan RMB or 1 000-3 000 Yuan RMB groups (both P<0.05, OR=4.34 and 1.95 respectively, compared with the staffs reporting family monthly income >3 000 Yuan RMB per capita) and the job rotation staffs (P<0.05, OR=2.54, compared with the no job rotation staffs). According to the results of ERI, higher occupational stress was found in the staffs reporting family monthly income <1 000 Yuan RMB group (P<0.05, OR=3.29, compared with the family income >3 000 Yuan RMB group), the secondary or tertiary hospital staffs (P<0.05, OR=2.70 and 1.98 respectively, compared with the primary hospital staffs), nurses (P<0.05, OR=2.50, compared with the other staffs), and the staffs reporting 40-60 or > 60 working hours per week (both P<0.05, OR=2.55 and 6.83 respectively, compared with the < 40 working hours per week staffs).
Conclusion Medical staff may suffer from high occupational stress and the common impact factors are family monthly in come per capita, hospital level, job position, working hour per week, and rotation system. Relevant health policies are necessary to control their stress at work to promote occupational health.
