Abstract
Objective– To our knowledge, only two controversial papers studied bone age (BA) at diagnosis in diabetic children. The aim of this study was to compare chronological age (CA) and BA and to evaluate the impact of glycated hemoglobin (HbA1c) on BA in children at diagnosis of type 1 diabetes.
Research design and methods– In 496 diabetic children height was measured at diagnosis and height SDS was calculated using the British 1990 growth reference. BA was determined according to Greulich and Pyle and HbA1c levels were measured.
Results– Height is normal for age and gender. No significant difference was found between CA and BA and there was no correlation between Δ (BA-CA) and HbA1c.
Conclusions– This study showed that height and bone maturation are normal for age and gender and independent of HbA1c at diagnosis of type 1 diabetes.
