AimsThis study aimed to investigate the effect of carbohydrate counting (carbC), with or without an automated bolus calculator (ABC), in children with type 1 diabetes treated with multiple daily insulin injections.MethodsWe evaluated 85 children, aged 9-16 years, with type 1 diabetes, divided into four groups: controls (n = 23), experienced carbC (n = 19), experienced carbC + ABC (n = 18) and non-experienced carbC + ABC (n = 25). Glycated haemoglobin (HbA1c), insulin use, and glycaemic variability - evaluated as high blood glucose index (HBGI) and low blood glucose index (LBGI) - were assessed at baseline and after 6 and 18 months.ResultsAt baseline, age, disease duration, BMI, HbA1c, insulin use, and HBGI (but not LBGI; p = 0.020) were similar for all groups. After 6 months, HbA1c improved from baseline, although not significantly - patients using ABC (according to manufacturer's recommendations) HbA1c 7.14 ± 0.41% at 6 months vs. 7.35 ± 0.53% at baseline, (p = 0.136) or without carbC experience HbA1c 7.61 ± 0.62% vs. 7.95 ± 0.99% (p = 0.063). Patients using ABC had a better HBGI (p = 0.001) and a slightly worse LBGI (p = 0.010) than those not using ABC. ABC settings were then personalised. At 18 months, further improvements in HbA1c were seen in children using the ABC, especially in the non-experienced carbC group (â0.42% from baseline; p = 0.018).ConclusionsCarbC helped to improve glycaemic control in children with type 1 diabetes using multiple daily injections. ABC use led to greater improvements in HbA1c, HBGI and LBGI compared with patients using only carbC, regardless of experience with carbC.
