Objective To understand the occupational stress and the prevalence of chronic non-communicable diseases (chronic diseases) among medical workers in Xinjiang tertiary grade A hospitals, and to complete related epidemiological databank.
Methods Using cluster sampling method, 2 036 medical workers were selected from three Xinjiang tertiary grade A hospitals. A survey was conducted using Job Stress Scale and Chronic Non-communicable Diseases Prevalence and Behavioral Risk Factors Questionnaire. Descriptive analysis was used to describe the medical workers' occupational stress and prevalence of chronic diseases. Chi-square test was used to analyze the differences of chronic diseases prevalence in different occupational stress groups. Logistic regression models were used to analyze the influencing factors of chronic diseases.
Results The low (job stress index, <3.89), medium (3.89-4.37), and high (>4.37) occupational stress groups consisted of 414 (22.4%), 931 (50.4%), and 502 (27.2%) medical workers, respectively; namely 77.6% of the medical workers were in medium or high occupational stress level. The top four chronic diseases were neck and lumbar diseases (24.6%), chronic digestive system diseases (21.5%), hypertension (14.9%), and hyperlipidemia (10.1%), which were significantly varied among groups of different occupational stress levels (P<0.05). Besides, according the logistic regression analysis after adjusting demographic characteristics, increased job stress indexOR (95%CI):6.172 (3.542-8.323) and job pressure indexOR (95%CI):5.134 (2.706-8.822) were associated with increased risks of chronic diseases.
Conclusion The occupational stress level and the prevalence rate of chronic diseases are both high in the medical workers in Xinjiang tertiary grade A hospitals. The chronic diseases prevalence rates vary in the groups with different occupational stress levels, and occupational stress may increase the risks of chronic diseases in medical workers.
