[The epidemiological characteristics and correlated factors of daily hassles for thermal power plant workers].

ABSTRACT

OBJECTIVE: This study aimed to investigate the epidemiological characteristics and correlated factors of daily hassles among thermal power plant workers. METHODS: A mass screening of daily hassles and correlated factors was conducted on 498 workers from a thermal power plant in Zhengzhou in July, 2008. The questionnaires included Daily Hassles Questionnaires, Work Roles Questionnaires, Job Content Questionnaires (Chinese version), Effort-Reward Imbalance (Chinese version), Work Locus of Control Scale and Type A Behavior Scale, with content covering demographic characters and occupational stress correlated factors among subjects. The daily hassles was divided into lower level and higher level according to scores, and the epidemiological characteristics and correlated factors of daily hassles were analyzed. RESULTS: A total of 446 qualified questionnaires were obtained, effective response rate was 89.6% (446/498). For respondents, the age was (36.96 ± 6.49) years old, working length of the current job was (12.05 ± 7.54) years, the daily hassles scores was (9.01 ± 2.50), and the prevalence rate of the higher level of daily hassles was 34.1% (152/446). The multiple non-conditional logistic regression analysis showed 5-14 years' working length of current job (OR = 0.451, 95%CI 0.225 - 0.904), average income > 3000 yuan(OR = 0.372, 95%CI 0.202 - 0.684), reward (OR = 0.557, 95%CI 0.325 - 0.954) and coping strategy (OR = 0.552, 95%CI 0.330 - 0.925) were negatively correlated with daily hassles, and shift-work (OR = 1.887, 95%CI 1.108 - 3.215), effort (OR = 2.053, 95%CI 1.198 - 3.519), psychological demand (OR = 1.797, 95%CI 1.049 - 3.078), negative affectivity (OR = 3.421, 95%CI 2.065 - 5.668) were positively correlated with daily hassles. CONCLUSION: The prevalence rate of the higher level of daily hassles was considerable high for thermal power plant workers. Its negative correlated factors included 5 - 14 years' working length of the current job, average income > 3000 yuan, reward and coping strategy and its positive corelated factors included shift-work, effort, psychological demand and negative affectivity.
