Abstract: Objective To investigate the status of blood glucose control in patients with type 2 diabetes mellitus （T2DM） and its related factors， so as to provide scientific basis for adjusting the management of diabetic patients.Methods All T2DM patients registered in a hospital of Ya'an City were investigated， including basic information （gender， age， course of disease， education level， etc.）， compliance with hypoglycemic drugs， exercise， blood glucose monitoring， diet control， complications of diabetes， etc.， and morning venous blood was collected for detection of HbA1c. The results were analyzed by descriptive analysis， and the influencing factors of blood glucose control were analyzed by univariate and multivariate analysis.Results A total of 1 073 T2DM patients aged 38-86 years were investigated， with an average age of （62.53 ± 7.36） years， and more males （711 cases， 66.26%）. The education level was mainly in junior high school and senior high school / secondary specialized school， accounting for 58.06%. The main course of diabetes was＜5 years， accounting for 46.69%. Among them， 250 cases reached the standard of blood glucose control， with a rate of 23.30%. Multivariate logistic regression analysis showed that the older the age （OR＝2.776）， the better the compliance of hypoglycemic drugs （OR＝3.225）， the better the exercise habits （OR＝2.213）， the frequency of blood glucose monitoring≥10 times per month （OR＝2.442）， and the more strict the diet （OR＝4.200）， the more likely the T2DM patients to reached the standard of blood glucose control.The more complications （OR＝0.287） and the longer the course of disease （OR＝0.325），the lower the possibility to reached the standard of blood glucose control.Conclusion The blood glucose control level of T2DM patients in this hospital is not ideal， and there are many factors affecting the blood glucose control level of patients with diabetes in this area. The relevant departments should adjust the policies according to the characteristics of the population to ensure the blood glucose control of patients and avoid the complications.
