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 from baseline to 24 and 36 weeks, respectively). No severe hypoglycemic events were reported. Diabetes distress was slightly higher in the six-pair group.

CONCLUSIONS:
Our results demonstrated that BG testing at six pairs/week, three pairs/week, and seven points for 3 days/month were all effective in improving glycemic outcome, with greater reduction of HbA1c level in the seven-point for 3 days/month group, without increasing burdensome distress in SMBG.
