Abstract: Objective To analyze the relationship between carotid intima-media thickness (CIMT) and metabolic syndrome (MS), and explore risk factors for CIMT incrassation in Tianjin policemen. Methods Fifty MS patients (MS group) and 50 healthy people (control group) in health examination of Tianjin policemen were enrolled in this study. The question⁃ naire survey(family history， past medical history， present history， living habits and occupational stress factors) were recorded in two groups of patients. The blood indicators (fasting plasma glucose, triglycerides, total cholesterol, high density lipopro⁃ tein cholesterol, low density lipoprotein cholesterol, homocysteine) were detected. The color Doppler was used to measure CIMT incrassation, and incrassation ratio was calculated. The relative indicators were compared between two groups. The logistic regression model was used to analyse the influencing factors of carotid artery intima-media thickness. Results CIMT and CIMT incrassation ratio (communis, internal and external carotid) were significantly higher in MS group than those of control group (P＜0.01). The risk factors for CIMT included family history of hypertension, chronic stress, smoking, family history of diabetes, high fat diet and high homocysteine levels, and dairy products were protective factors for CIMT incrassa⁃ tion. Conclusion The reason of carotid artery intima-media thickness is diversity. The healthy lifestyle and clinical intervention to retard CIMT are advocate, which are conducive to the control of atherosclerosis.
