Comparison Of Four Diagnostic Criteria For Metabolic Syndrome And On The Relationship Between Occupational Stress And Metabolic Syndrome Among Police

Objective:1 The aim of this study was to explore and compare the prevalence and the differences of application for metabolic syndrome among the police in Tianjin.2 To study the relationship between occupational stress and metablic syndrome, and to identify the main causing stress and occupational factors.Methods:1 A survey was conducted among 10944 police (men 9886,women 1058) while physical examination was undergoing from March 2007 to March 2008 in Tianjin police hospital. The MS diagnosed and compared according to the NCEP-ATPⅢ, the modified NCEP-ATPⅢ, the CDS and the IDF criterions, respectively, the differences and agreement in the prevalence rates of MS was analyzed.2 In the cross-sectional survey,1544 policemen were randomly selected from DaGang, XiQing,BaoDi and JiXian in TianJin,and they were measured with occupational stress inventory-revised(OSI-R)and standardized health questionnaire. Blood pressure, blood triglyceride and blood glucose and so on were also measured at the same time. Metabolic syndrome was diagnosed by means of using Chinese Diabetes Society(CDS)definition. The relevant factors of metabolic syndrome were analyzed by chi-square test and unconditional logistical regression analysis.Results:1 The age-adjusted prevalences of MS werel8.60%,10.57%,9.97%和20.31%, according to the IDF,CDS,ATPⅢand ATPⅢ* criterions, respectively. The prevalence of men was higher than that of women(P< 0.001=, and its prevalence was not increased with age, The CDS criterion could be used to detect the higher percent of risk factor aggregation among four criterions, and 12.4%of subjects without MS diagnosed by IDF criterion presented at least 3 risk factors. The agreement rate of four diagnostic criterions was 79.36%. The IDF and ATPⅢ* has the highest agreement (k=0.94).2 The results of the unconditional logistical regression analysis shows that:police in the medium category of occupational stress were more likely to become metabolic syndrome than in the lowest category (odds ratio 2.08,95%confidence interval 1.03 to4.20); and police in the highest category of occupational stress were more likely to become metabolic syndrome than in the lowest category (odds ratio 2.16,95% confidence interval 1.75). The species of police and length of service are two ccupational factors of poliemen, as a reference of household registration police, security policeis more likely to become metabolic syndrome (OR=2.77,95%CI 1.83～4.19), as a reference group of 10 years of service, the length of service for 20 to 30 years has 4.06-fold of the possibility than the reference group (OR= 4.06,95%CI 2.39～7.04).; The main occupational stress factors are the three fators as follows:role ambiguity (RA), role insufficiency (RI)and responsibility (R),the protective factors were recreation (RE), self-care (SC)and social support (SS).Conclusion:1 The prevalence of MS is significantly higher among police in Tianjin.. The male aged from 55～65 and female aged from 65～75 are high-risk population. The CDS criteria is more suitable for Chinese population,and its criteria of obesity was suggested to be waist circumferences instead of BMI. The cutoff of fasting plasma glucose could be lowered to 5.6mmol/L. The agreement between IDF and ATPⅢ* criterion is the best.2 The higher level of occupational stress, the greater likelihood of occurrence of ms will be; the one who has abundant resources will have the the lower likelihood of MS occurrence; The length of service for 20 to 30 years group of police officers is prone to become MS. (P<0.05). The main occupational stress factors are role ambiguity (RA), role insufficiency (RI)and responsibility (R),and the protective factors were recreation (RE), self-care (SC), and social support (SS).
