AIM: To evaluate the efficacy and safety of automated insulin delivery (AID) systems in very young children with type 1 diabetes (T1D). METHODS: PubMed, Embase, Scopus, and Web of Science were searched until 10 October 2025. Inclusion criteria were randomized controlled trials (RCTs); T1D populations under 7 years old; comparing AID systems with standard care (SC). Primary efficacy endpoint was the percentage of time-in-range of 70-180 mg/dL (TIR) derived from continuous glucose monitoring (CGM), secondary outcomes included glycated haemoglobin (HbA1c), other CGM metrics, and insulin dose. Safety endpoints included severe hypoglycaemia (SH) and diabetic ketoacidosis (DKA). RESULTS: = 82%, p 180 mg/dL; >250 mg/dL) and mean blood glucose were also observed in AID over SC (all p 0.05). CONCLUSION: AID systems may outperform SC in improving short-term glycaemic control (TIR, HbA1c, TAR) in very young children with T1D, without increasing time in hypoglycaemia, insulin dose, or risk of SH and DKA. These preliminary findings support the clinical potential of AID systems and highlight the need for longer term studies.
