Improving glycaemic control in children and adolescents presents unique problems
Type 1 diabetes affects one in 500 children and adolescents, and vascular complications remain a major cause of mortality and morbidity in adult life. Blood glucose targets have fallen since confirmation of the unequivocal relationship between glycaemic control and microvascular complications.1,2 In this issue of the Journal (page 235), Craig et al present a population-based, cross-sectional study of 1190 children and adolescents with type 1 diabetes in New South Wales and the Australian Capital Territory.3 Their median HbA1c level of 8.2% probably reflects some selection bias, because 571 (33%) of the population did not participate. However, this level of glycaemic control still represents a considerable improvement over the past 10 years4 and is comparable to levels found in international studies of children with type 1 diabetes.5 This trend accompanies the increasing use of intensive management in children and adolescents, but also the worrying rise in the incidence of severe hypoglycaemia.
