Objective: This study was done to evaluate the accuracy and safety of measuring glucose with the GlucoWatch ® biographer in children and adolescents with diabetes. Methods: Accuracy was assessed by comparing biographer glucose measurements with hourly blood glucose measurements using the HemoCue (Aktiebolaget Leo, Helsingborg, Sweden) Photometer for up to 12 h of monitoring. Safety was evaluated by examining the biographer application sites immediately upon removal of the devices, and then at regular intervals. Results: Sixty‐six subjects each wore three biographers at sites including the forearm, upper arm, leg, and torso. For forearm biographers, the mean absolute relative difference between biographer readings and blood glucose was 21%. Ninety‐five per cent of biographer readings fell into the A or B regions of the Clarke error grid, and 97.3% into the A or B regions of the consensus error grid. Data from biographers worn at the alternative sites were similar to data from the forearm biographers. Two strong reactions to the adhesive pad of the biographer AutoSensor were observed. Most skin reactions were mild. Conclusions: The GlucoWatch biographer is well tolerated by children and adolescents with diabetes. Performance is similar when the device is worn at different anatomical sites, and is similar to the performance on the forearm, previously reported in adults.
