Lehmann V, Zueger T, Zeder A, et al. - Researchers intended to determine if there is a connection between daily carbohydrate (CHO) intake and glycemic control in adult hybrid closed-loop (HCL) users with type 1 diabetes (T1D). Mean individual daily CHO intake (MIDC) and relative deviation from MIDC (≤ 80% low; 81–120% medium, >120% high CHO consumption) have been contrasted with parameters of glycemic control evaluated by continuous glucose monitoring. Records of 36 patients (26 male, 10 female; age 36.9 ± 13.5 years; HbA_1c 7.1 ± 0.9% [54 ± 10 mmol/mol]) produced 810 days of data (22.5 ± 6.7 days per patient). Data reported that time in range (70–180 mg/dL) for low, medium, and high CHO consumption was 77.4 ± 15.4%, 75.2 ± 16.7%, and 70.4 ± 17.8%, respectively. Using an HCL system, daily CHO intake was inversely linked to glycemic control in adults with T1D. In order to improve glucose regulation in HCL users, lower CHO intake may be a strategy.
