Comparison of Different Models of Structured Self-Monitoring of Blood Glucose in Type 2 Diabetes

Abstract Background: The aim of this study is to compare the effectiveness of different models of structured self-monitoring of blood glucose (SMBG) in non–insulin-treated type 2 diabetes. Subjects and Methods: This was a prospective, three-arm, randomized, 36-week trial. There were 138 participants with a mean age of 58.7 years and glycated hemoglobin A1c (HbA1c) level of 8.72% who were allocated to the following groups: six-pair glucose test of pre- and postprandial blood glucose (BG) per week (n = 43); three-pair glucose test of pre- and postprandial BG per week (n = 39); and seven-point BG testing before and after each meal and at bedtime over a course of 3 days in 1 month (n = 40). Results: The intention-to-treat analysis revealed that all three groups showed significant reductions in HbA1c levels. Comparisons among the groups revealed that only the seven-point group had a significant greater reduction of HbA1c level compared with the three-pair group (between-group mean difference of −0.86 and −0.80...
