Summary:Aims/Introduction We investigated the relationship between the frequency of self‐monitoring of blood glucose (SMBG) and glycemic control in type 1 diabetes mellitus patients on continuous subcutaneous insulin infusion (CSII) or on multiple daily injections (MDI) using data management software. Materials and Methods We recruited 148 adult type 1 diabetes mellitus patients (CSII n = 42, MDI n = 106) and downloaded their SMBG records to the MEQNET™ SMBG Viewer software (Arkray Inc., Kyoto, Japan). The association between the SMBG frequency and the patients' hemoglobin A1c (HbA1c) levels was analyzed using the χ2‐test and linear regression analysis was carried out to clarify their relationship. Results The odds ratio of achieving a target HbA1c level of <8% (63.9 mmol/mol) was significantly higher in subjects with SMBG frequencies of ≥3.5 times/day compared with those with SMBG frequencies of <3.5 times/day in the CSII group (odds ratio 7.00, 95% confidence interval 1.72–28.54), but not in the MDI group (odds ratio 1.35, 95% CI 0.62–2.93). A significant correlation between SMBG frequency and the HbA1c level was detected in the CSII group (HbA1c [%] = –0.24 × SMBG frequency [times/day] + 8.60 [HbA1c {mmol/L} = –2.61 × SMBG frequency {times/day} + 70.5], [r = –0.384, P = 0.012]), but not in the MDI group. Conclusions A SMBG frequency of <3.5 times per day appeared to be a risk factor for poor glycemic control (HbA1c ≥8%) in type 1 diabetes mellitus patients on CSII. The SMBG frequency was correlated with the HbA1c level in the CSII group {HbA1c (%) = −0.24 × SMBG frequency (times/day) + 8.60 [HbA1c (mmol/L) = −2.61 × SMBG frequency (times/day) + 70.5], (r = −0.384, P = 0.012)}, but not in the MDI group {HbA1c (%) = [−0.16 × SMBG frequency (times/day)] + 8.75, [HbA1c (mmol/mol) = −1.73 × SMBG frequency (times) + 72.1 mmol/mol], (r = −0.132, P = 0.177)}.
