Abstract: Objective To investigate the compliance of blood glucose control in elderly patients with type 2 diabetes mellitus（T2DM）, and the effect of drug compliance on it. Methods From January to December in 2019, patients with T2DM aged over 60 years old who visited a hospital in Chaoyang District of Beijing were included as the research object, their compliance of blood glucose control were investigated, and the influence factors of blood glucose control and the drug compliance were analyzed. Results Among the 1 304 elderly patients with T2DM, 621 were males and 683 were females, aged 60-85 years old, with an average age of （69.6±6.9） years. The average course of T2DM was （8.9±1.7） years. The average HbA1c of T2DM patients was （7.66±1.95） %. The blood glucose control of 363 elderly patients with T2DM met the standard, the compliance rate was 27.84%; 291 cases （22.32%） had good drug compliance. Multivariate Logistic regression analysis showed that BMI≥24.0 （OR=0.751）, the older the onset age （OR=0.715）, complicated with hypertension （OR=0.150）, complicated with dyslipidemia （OR=0.197）, the course of T2DM > 10 years （OR=0.518） were less likely to meet the standard of blood glucose control in elderly patients with T2DM. Elderly T2DM patients with diet control （OR=3.758） and good drug compliance （OR=3.323） were more likely to meet the standard of blood glucose control. Conclusion The blood glucose control and drug compliance of elderly patients with T2DM are not ideal. Diet control and improving drug compliance are important strategies to effectively control the blood glucose level of patients and delay the occurrence of complications.
