ABSTRACT
In this cross-sectional survey,2 682 traffic policemen in Tianjin were enrolled,and they were tested with Occupational Stress Inventory-Revised (OSI-R) and Symptom Checklist 90 (SCL-90).Body mass index,blood pressure,fasting blood glucose,triglycerides,and high-density lipoprotein-cholesterol ( HDL-C ) were also determined at the same time. Correlation analysis showed that body mass index was positively correlated with somatization ( r =0.039,P =0.045 ),hostility ( r =0.046,P =0.01 8 ),and psychoticism ( r =0.041,P =0.036).Systolic blood pressure was positively correlated to somatization (r =0.056,P =0.004 ),obsessive-compulsiveness ( r =0.044,P =0.023 ),interpersonal sensitivity ( r =0.041,P =0.034 ),depression ( r =0.039,P =0.043),anxiety ( r =0.055,P =0.004 ),and psychoticism ( r =0.051,P =0.009 ).Diastolic blood pressure was positively correlated 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 ).Fasting blood glucose was positively correlated to somatization ( r=0.042,P=0.028 ).Multiple regression analysis showed that occupational stress factors were role boundary,physical environment,responsibility,recreation,role ambiguity,role overload,and cognitive coping.Among these factors,role ambiguity and cognitive coping reduced occupational stress while others increased the stress.The results of the unconditional logistical regression analysis showed that there is an independent association of metabolic syndrome with somatization,role insufficiency,and physical strain for the task and body tension ( P＜0.01).
