Conflicting information exists in the literature regarding the merit of frequent SMBG to control blood glucose levels among type 2 diabetics. The American Diabetes Association (ADA) recommends SMBG to reach and maintain normal or near-normal glucose levels among both type 1 and type 2 diabetics. OBJECTIVE: The objective of this study was to assess whether self-reported adherence to SMBG was related to HbA1C among type 2 diabetics. METHODS: Type 2 diabetics from a county family clinic served as the study population. Participants completed a self-administered survey during seminars held at the clinic. Chart reviews were conducted to retrieve baseline (at the time of the seminar) and follow-up (within one year after the seminar) HbA1C levels, as well as indication for change in pharmacotherapy. Multiple regression was used to assess the relationships between SMBG adherence and HbA1C, while controlling for demographic (i.e., age, race, and income) and biological (i.e., duration of diabetes, comorbidities, change in pharmacotherapy, and baseline HbA1C) variables. A priori significance level of .05 was chosen. RESULTS: Participants (n = 158) were 56.9 (SD: 12.3) years old, non-white (70.1%), with annual family income between $20,000 and $30,000, on average. Their adherence to SMBG was 49.2% (SD: 40.3), which was not associated with follow-up HbA1C level. Duration of diabetes, change in pharmacotherapy, and the number of complications were significantly and positively associated with follow-up HbA1C. CONCLUSIONS: SMBG adherence was not significantly related to follow-up HbA1C among type 2 diabetics. Maintaining normal or near-normal blood glucose levels may be more likely associated with adherence to diet, exercise, and medication. Health practitioners should view SMBG as a tool, rather than a therapy by itself, and recommend its use to those patients who can and are willing to act based upon the results.
