Abstract

The effect of nutrition education using self-monitoring of blood glucose on glycemic control was investigated in the present study. Of 36 males and 25 females aged 30 - 69 years under outpatient treatment at 3 hospitals in Niigata prefecture, Japan, 61 non-insulin-treated obese type 2 diabetes patients with HbA1c of 6.9% - 9.3% and body mass index of 25 kg/m2 or higher were randomly allocated. Thirty and 31 patients were analyzed in intervention and control groups, respectively. The intervention group performed self-monitoring of blood glucose 2 hours after supper twice a week for 6 months and underwent nutrition education on the association between meals and postprandial blood glucose once every 2 months. The primary outcome was glycated hemoglobin, with the secondary outcome of body mass index. Stages of change for eating the appropriate supper amount were investigated to verify the process of the educational effect, and satisfaction with diabetes treatment and well-being were investigated to verify the continuity of treatment. On intention-to-treat analysis, glycated hemoglobin (mean ± SD) decreased from 7.9% ± 0.6% to 7.7% ± 0.6% in the intervention group but increased from 7.9% ± 0.6% to 8.1% ± 0.6% in the control group, showing a significant difference in the change after intervention between the groups (p = 0.027). In the intervention group, body mass index decreased from 28.9 ± 3.8 to 28.4 ± 3.7 kg/m2 (p = 0.019), the stages of change to learn the appropriate amount of supper progressed (p = 0.026), and satisfaction with diabetes treatment increased (p = 0.031).
