Objective: To assess the prevalence of type 2 diabetes mellitus (T2DM) and impared glucose regulation(IGR) in the residents of Baoding City, including 1-impaired fasting glucose(1-IFG), 1-impaired glucose tolerance (1-IGT) and IFG/IGT, to identify the main risk factors of abnormal glucose regulation.
Methods: A sample of 3212 community residents aged over 40 years old was selected from three communities of Baoding City by random cluster sampling. The survey was conducted by trained investigators using a standardized questionnaire. The subjects received physical examination and laboratory test, such as SBP, SDP, TC, TG, LDL-C, HDL-C, FBG, 2h PG, WHR and BMI. The data were analyzed by Accumulative Logistic Regression.
Results: The standardized prevalence of T2DM, -IFG, 1-IGT and IFG/IGT was 19.03%, 1.42%, 5.92% and 1.34%, and 27.72% of residents over 40 yeas old in Baoding City threatened by the trouble of abnormal glucose regulation. The results demonstrated that the gender, age, occupation, fruit intake, temper or disposition, BMI, WC, WHR, SBP, TG, DM family history and the history of fetal macrosomia (female only) were significantly associated with the abnormal glucose regulation, but taking more fruits and the female sex were protective factors. Cardio-cerebrovascular disease was the highest among the complications prevalent in diabetic patients, more than one complication is common, and the detection rate of new diabetic patients was 8.19%.
Conclusion: The prevalence of T2DM is high in the residents of Baoding City, which is influenced by many factors.
