Application of self-regulatory behavioral management in postprandial self-blood glucose monitoring for noninsulin treated type 2 diabetic patients

Aim: The purpose of this study is to investigate the effect of self-monitoring of blood glucose (SMBG) on glycemic control in insulin-naive type 2 diabetic patients comparing SMBG plus self-regulatory behavioral education, and SMBG plus individual education.Methods: Participants with glycated hemoglobin A1C (HbA1C) of 7.5-12% were enrolled in this 24-week, prospective study. Forty-two and forty participants received SMBG plus selfregulatory behavioral education, and SMBG plus individual education, respectively. The glycemic and behavioral attitudes outcomes were evaluated.Results: The A1C level decreased in both groups, from 9.41± 1.7% to 7.84± 0.83% in the SMBG plus self-regulatory behavioral education and 9.62 ±1.08% to 9.09± 1.1% in the SMBG plus individual education. However, the postprandial glucose (PPG) level sustained more significant decreases from 277.1 ±80.1 to 175.7 ±53.9 mg/dL in the SMBG plus self-regulatory behavioral education, and from 261.2 ±80.5 to 221.6 ±41.2 mg/dL in the SMBG plus individual education. The frequency of PPG monitoring increased from 0.1 ± 0.81 to 3.46 ± 2.81 times/week in SMBG plus self-regulatory behavioral education, whereas it increased from 0.13± 0.78 to 1.01± 0.89 in SMBG plus individual education. The amount of carbohydrates consumed per day decreased and the amount of physical activity performed per week increased significantly in self-regulatory behavioral education group.Conclusions: The use of this model of SMBG plus self-regulatory behavior education appears to have resulted in superior improvements in glycemic control and behavioral outcomes compared with those achieved by SMBG plus individual education.
