Characteristics and learning effects of the predictability of the self-monitored blood glucose level in children with type 1 diabetes.
To know how the blood glucose level obtained by SMBG are recognized by type 1 diabetic children with relatively stable HbA(1c), they were requested to record the levels estimated before SMBG, and the estimated and SMBG levels of blood glucose were compared. In error grid analysis, the children overestimated the blood glucose level when it was lower than around 140 mg/dl, and underestimated it when it was higher than 140 mg/dl in daily life. Seventy-nine percents of the results were included in areas A and B in the error grid analysis. It is likely that the predictability of blood glucose levels in daily life was not difficult for the children with relatively stable HbA(1c) (6.9 +/- 0.5%). Error grid analysis also showed that the results were changed to higher ranks in the second half of this study period. This tendency was observed irrespective of the SMBG level, indicating the learning effects.
