Abstract: Objective To analyze the prevalence and influencing factors of metabolic syndrome （MS） in patients with type 2 diabetes mellitus （T2DM）, and provide reference data for related prevention and control work. Methods The patients with T2DM diagnosed from January to December in 2019 in a tertiary hospital of Zhengzhou City were selected as the research objects. The basic information of the research objects was collected and the physical examination and physiological and biochemical indexes were detected. Descriptive epidemiological analysis was used to analyze the data, and univariate and multivariate analysis methods were used to analyze the influencing factors of MS. Results A total of 1 053 patients with T2DM were included in this study, including 517 males and 536 females. The age ranged from 37 to 76 years, with an average of （58.2±6.4） years old. The BMI ranged from 18.2 to 27.9, with an average of （23.1±2.7）. The course of diabetes was 1-19 years, with an average of （9.6±3.5） years. The blood glucose control level reached the standard in 792 cases, accounting for 75.2%. There were 519 cases of MS, with a prevalence rate of 49.3%. Multivariate Logistic regression analysis showed that T2DM patients who were female （OR=2.826）, with older age（OR=2.748）, higher BMI （OR=2.208）, history of other basic diseases （OR=3.916） and family history of MS （OR=3.264） had higher risk of MS, and had higher physical exercise frequency per week （OR=0.776）, blood glucose control level reached the standard （OR=0.679） had lower risk of MS. Conclusion The prevalence of MS in patients with T2DM is at a high level, its occurrence is mainly affected by gender, age, BMI, physical exercise, blood glucose control level, other basic diseases and family history of MS, targeted interventions should be actively taken to reduce the occurrence of MS.
