OBJECTIVE： To provide reference for improving medication compliance and therapeutic efficacy in community patients with type 2 diabetes mellitus （T2DM） in China. METHODS： The data was from the “Economic Study of Diabetic Medications in Patients with T2DM in China”， which was conducted by China Center for Health Economic Research of Peking University. Both univariate analysis and Logistic regression model were used for single factor analysis and multiple factor analysis of medication compliance. RESULTS： Totally 2 236 community T2DM patients were included. The rate of good medication compliance was estimated at as low as 23.48％. Monthly household income and duration of the disease had significant impact on medication compliance. Incidence of good the medication compliance for patients with monthly household income ≥6 000 yuan and during 3 000-＜6 000 yuan， compared to those with monthly household income ＜3 000 yuan， were 70.8％ [95％CI（0.532，0.944）] and 78.5％ [95％CI（0.614，1.004）] respectively. Incidence of good medication compliance for the patients with 5 to 10 years and ＞10 years of disease duration， compared to those with ＜5 years of disease duration， were 69.0％ [95％CI（0.542， 0.878）] and 59.1％ [95％CI（0.459， 0.760）] respectively. CONCLUSIONS： The medication compliance among community patients with T2DM in China was generally poor. Longer duration of the disease and higher monthly household income are associated with poorer medication adherence.
