Abstract: ObjectiveTo investigate the status and related factors of selfmonitoring blood glucose(SMBG) in patients with type 2 diabetes mellitus (T2DM)， and to explore the relationship between SMBG frequency and glycemic control. MethodsA total of 289 T2DM patients who hospitalized in Tianjin Metabolic Disease Hospital were enrolled in the study. A questionnaire survey was conducted on SMBG frequency， gender， age， duration， education， diabetes comprehensive management， blood glucose level， and related complications. ResultsAmong 289 eligible patients， the average SMBG frequency was 10.03 times per month， with 55.1% patients monitored no less than 4 times per month. Logistic regression analysis showed that dietary control， exercise therapy and HbA1c level were the main factors affecting regular SMBG (P<0.05). In addition， age， FBG， P2BG， whether received diabetes education， whether insulin treatment and whether presented hypoglycemia were independent effect for SMBG frequency(P<0.05)， there was no clear association between SMBG and diabetic complications（P＞0.05）. SMBG  frequency was negatively correlated with FBG， P2BG and HbA1c levels（r=-0.276，-0.360，-0.361，respectively；P＜0.05）；Oral hypoglycemic agents treated patients and insulin treated patients， when the SMBG frequency was at least 7.5 times per month (2 times / week)， 10.5 times per month (3 times / week)， respectively，the glycemic control can basically reach  the standard. ConclusionThe level of knowledge and monitoring quality of SMBG in  T2DM  patients were relatively low. In order to improve this situation， endocrinologists and nurses can develop individualized SMBG programs for patients， and strengthen the education on diabetesrelated diet， exercise therapy and blood glucose monitoring knowledge. SMBG can improve glycemic control， while glucose levels can also affect SMBG. The relationship between SMBG and diabetic complications still needs further proof.
