Description

Although it is known to be useful for controlling the postprandial blood glucose level of subjects with type 1 diabetes mellitus (T1D), carbohydrate counting (CC) has not been popular in Japan. We propose a method for estimating the carbohydrate content using an individual's hands as a means of introducing CC. We demonstrated that the difference between our estimation, based on this method, and the precise count based on the food substitution list was within 10 g in over 90 % of 210 diabetic diets (1200-2000 kcal/day) and 50 diet record images. Moreover, we compared 12 T1D patients who performed CC with the hand counting method with another 10 T1D patients who performed CC using the conventional method. At 12 months after the introduction of CC, although no significant differences were observed in the HbA1c value or the body mass index of the patients in the two groups, the patients who used the hand counting method showed a significantly lower frequency of hypoglycemia. The results indicate that the hand counting method is reasonably accurate and clinically useful in the management of Japanese T1D patients.
