Self-monitoring of blood glucose in type 2 diabetes: Results of the 2011 Survey on Living with Chronic Diseases in Canada.

Background For insulin-treated patients with type 2 diabetes mellitus (T2DM), self-monitoring of blood glucose (SMBG) may be vital in adjusting insulin dosages. For patients who do not use insulin, evidence supporting the use of SMBG is inconclusive. Methods The prevalence, frequency and correlates of SMBG are examined. Data pertain to 2,682 individuals aged 20 or older with T2DM who responded to the 2011 Survey on Living with Chronic Diseases in Canada. Multivariate prevalence rate ratios for associations between respondents' characteristics and their use of SMBG were derived using binomial regression models. Results A large majority of the study population (87.8%) reported SMBG. No difference in the prevalence of SMBG was observed between oral medication users compared with insulin users; however, the frequency of SMBG was lower for those taking oral medication only. Significant determinants of SMBG were a health professional's recommendation, having insurance coverage, and receiving an A1C test from a health professional. Interpretation The use of SMBG by adults with T2DM is common, and does not differ between those taking oral medication only and those treated with insulin.
