Does minimed 780GTM insulin pump system affect energy and nutrient intake?: long-term follow-up study

Objective We evaluate the energy and nutrient intake of children, adolescents, and young adults with type 1 diabetes (T1D) who started to use automated insulin delivery (AID) systems before the transition and during follow-up for 6 months in a real-world setting. Research design and methods Twenty-nine people with T1D (PwD) who started to use MiniMed 780G TM participated in the study. Participants’ 3-day food diaries and glycemic outcomes were analyzed at baseline and after (the 3 rd and 6 th month) switching to an advanced hybrid closed-loop system (a-HCL). Results Mean carbohydrate, protein, and fat intake (energy %) at baseline were 49.1 ± 4.5, 17.8 ± 2.3, and 33.0 ± 3.9, respectively, and there were no statistically significant differences during the follow-up period. However, low fiber (10 energy %) intake in PwD, both baseline and follow-up period. The median auto-correction bolus ratio was 14.0 (9.5)% at auto mode after 14 days, 18.0 (11.0)% at the 3 rd month, and 19.0 (7.5)% at the 6 th month ( p
