| Objective1. We would provide a reference for the traffic polices to improve their self-awareness of health protection and to explore effective control measures by studying the epidemic status of metabolic syndrome (Metabolic Syndrome. MS) and its influencing factors on some of Tianjin traffic police.2. We would explore the relationships between occupational stress and psychological factors associated with metabolic syndrome by studying occupational stress factors and psychological factors on some of the Tianjin traffic police.MethodsIn the cross-sectional survey,2682traffic police were randomly selected in Tianjin, and they were measured with occupational stress inventory-revised (OSI-R) and Symptom Checklist90(SCL-90). Body Mass Index (BMI), blood pressure, fasting blood glucose (FBG), triglyceride (TG), and High-density lipoprotein (HDL-C) were also measured at the same time.Results1. The crude prevalence of MS for Tianjin traffic polices is27.11%. The prevalence rate for male is27.53%and the female prevalence is11.43%. The standardized prevalence rate of MS is24.53%, the male standardized prevalence rate is25.42%, and the female standardized prevalence rate is13.71%. The rate of men is higher than that of women, the difference of which was statistically significant (P<0.05).2. The correlation analysis on the various components of MS and psychological factors showed that:BMI was significantly positively related to somatization (r=0.039,P=0.045), hostility (r=0.046, P=0.018) and psychotics (r=0.041,P=0.036); SBP was significantly positively related to somatization (r=0.056,P=0.004), obsessive-compulsive (r=0.044,P=0.023) interpersonal sensitivity (r=0.041,P=0.034), depressed (r=0.039, P=0.043), anxiety (r=0.055,P=0.004) and psychoticism (r=0.051, P=0.009); DBP was significantly positively related to somatization (r=0.047, P=0.015), interpersonal sensitivity (r=0.042, P=0.030), anxiety (r=0.050. P=0.010) and psychoticism (r=0.047,P=0.014); FBG was significantly positively related to somatization (r=0.042, P=0.028) and TC was significantly positively related to somatization (r=0.046,P=0.018)3. According to the workload characteristics of the traffic police, it will be divided into four groups of the traffic polices as a lack of tension, moderate tension, medium tension and high tension groups, and comparing with the lack of tension group, BMI was significantly increased (P<0.01) in the moderate, moderate, and high tension group while systolic blood pressure (SBP) was significantly increased (P<0.05), and diastolic blood pressure (DBP) for the moderate stress group and the high tension group was significantly increased (P<0.05), fasting blood glucose (FBG) was obviously higher (P<0.05) too.4. The occupational tasks are divided into6items as task boundaries, work environment, role ambiguity, role overload, rational, sense of responsibility, leisure and entertainment to set questionnaires as6factors and4personal resources questionnaire factor, which showed that:the impact of factors for occupational stress of the traffic police is respectively descending in order as for the task boundaries, work environment, responsibility, entertainment, role ambiguity, role overload, rational (P<0.01), role ambiguity and the rationality of doing things to reduce occupational stress, and other five factors to increase occupational stress.5. Multiple regression analysis showed that:descending occupational stress factors were respectively role boundary, physical environment, responsibility, recreation, role ambiguity, role overload, cognitive coping. Among the total, role ambiguity and cognitive coping reduced occupational stress while others increased it. The results of the unconditional logistical regression analysis show that:there is an independent association of MS among somatization, role insufficiency and physical strain for the task and body tension. Body tension and the incidence of MS was independently associated symptoms of somatization, task discomfort, tense body risk factors for MS. Hostile, role ambiguity, work environment are abnormal risk factors of BMI while anxiety, task discomfort, terror and unusual risk factors are for SBP and self-care exception is protective factors for SBP. The interpersonal sensitivity, diet sleep and other factors, task discomfort may be the abnormal risk factors of DBP, and somatization symptoms may be the risk factors for FBG while working environment may be of the (abnormal) risk factors for HDL disease.Conclusion1. The MS prevalence of Tianjin traffic polices in this study was27.11%, being higher than the13.3%prevalence of MS of China’s general population, while male traffic police have higher MS percentage than that of the female traffic police, and the prevalence of the age over55years old is significantly higher than other groups.2. There were significant differences for BMI, SBP, DBP, and of FBG in different level of tension groups which showed occupational stress being the risk factors for MS. Multiple regression analysis showed that:descending occupational stress factors were respectively role boundary, physical environment, responsibility, recreation, role ambiguity, role overload, cognitive coping. Among the total, role ambiguity and cognitive coping reduced occupational stress while others increased it. The results of the unconditional logistical regression analysis show that:there is an independent association of MS among somatization, role insufficiency and physical Strain for the task and body tension.3. Psychological risk factors and occupational stress may be associated with metabolic syndrome factors. It suggests that effective psychological intervention modes should be prompted immediately to prevent and improve MS. |
