Factors associated with glycemic control in adults with type 1 diabetes mellitus on an insulin pump

OBJECTIVE: To explore the factors associated with glycemic control in adults with type 1 diabetes mellitus (T1D) on an insulin pump. METHODS: A total of 108 patients aged over 18 years and on an insulin pump therapy for >6 months were selected from 16 centers of Guangdong Type 1 diabetes Translational Medicine Study. They were classified into two groups according to the (American Diabetes Association) ADA Hemoglobin A1c target (7.0%). Those reaching the target (n = 59) were compared with those failed (n = 49) using ANOVA and Logistic regression. RESULTS: There were 75 females and 33 males with a median age of 32.0 (25.9-40.9) years and a median disease duration of 7.9(4.2-12.3) years. Logistic regression analysis revealed an odds ratio of 4.48(95%CI 1.53-13.15, P = 0.00) for total daily basal insulin dose within 0.2-0.3 units per kilogram, an OR of 1.31 (95%CI 1.05-1.63, P = 0.01) for self-monitoring of blood glucose (SMBG) and an OR of 3.43 (95%CI 1.18-10.01, P = 0.02) for males. CONCLUSION: Higher frequencies of SMBG and appropriate basal insulin dose are essential for adult patients with T1D on an insulin pump.
