Abstract: Objective To investigate the compliance of behavior and blood glucose control in patients with type 2 diabetes mellitus （T2DM）, and to provide a reference for blood glucose control and behavior intervention in T2DM patients. Methods From October 2020 to December 2021, the T2DM patients who were registered in a community service center cooperated with a tertiary hospital were selected. The basic data and behavioral compliance were obtained by questionnaire. The blood biochemical indexes of examination were used to evaluate the compliance of blood glucose control. The impact of behavioral compliance on blood glucose compliance in T2DM patients was analyzed. Results A total of 1 949 patients were included, 1 872 cases were effective, and the effective rate was 96.05%. There were 1 021 cases of blood glucose control that reached the standard, with a rate of 54.54%. There were statistically significant differences in compliance rates of blood glucose control among T2DM patients at different ages, educational levels, course of the disease, and other basic diseases （P＜0.05 or P＜0.01）. The compliance rates of medication following the doctor's advice, diet control, meals on time, regular physical exercise, smoking cessation, alcohol withdrawal, sleep guarantee, and blood glucose monitoring were 64.37%, 52.67%, 58.49%, 49.79%, 82.43%, 78.69%, 76.87%, 48.13%, respectively. Multivariate Logistic regression analysis showed that age （OR＝0.779）, educational level （OR＝2.257）, course of disease （OR＝0.689）, other basic diseases （OR＝0.483）, medication following the doctor's advice （OR＝3.543）, diet control （OR＝2.675）, meals on time （OR＝1.988）, regular physical exercise （OR＝2.054）, alcohol withdrawal （OR＝2.208）, and blood glucose monitoring （OR＝1.960） were the influencing factors of blood glucose control compliance in T2DM patients. Conclusions The behavioral compliance of T2DM patients need to be improved. In particular, compliance of medication following the doctor's advice, diet control, meals on time, regular physical exercise, alcohol withdrawal, and blood glucose monitoring are closely related to the compliance rate of blood glucose control. Targeted intervention measures should be strengthened to improve the behavioral compliance of patients and control the development of T2DM.
