Objective: To investigate the status of self-monitoring of blood glucose (SMBG) among patients with type 2 diabetes mellitus in Shanghai and analyze the factors affecting the frequency of SMBG.

Methods: A total of 987 Chinese subjects with type 2 diabetes mellitus aged 20 to 80 years old was included in the present study from August 2017 to December 2017. A standard questionnaire was completed. The frequency of SMBG and related factors of hyperglycemia were analyzed. The subjects were divided into two groups according to the frequency of SMBG. The relatively high frequency group (RHF) (more than twice a week) and the relatively low frequency group (RLF) (one and twice a week).

Results: Among all the subjects, 337 (34.2%) of them were in the RHF group, and 648 (65.8%) were in the RLF group. The number of patients who monitored blood glucose three times a day and more than three times a day was less (16 and 43, 1.6% and 4.4% respectively). Majority of patients adjusted their blood glucose levels through exercise (38.9%) and diet (38.1%), rather than drug (7.7%) after SMBG. Other methods (15.2%) were also used to alleviate hyperglycemia. Multivariate logistic regression analyses showed that age, duration of diabetic history, glycated hemoglobin, educational levels, insulin usage were factors influencing the frequency of SMBG in patients.

Conclusions: The current status of SMBG among diabetic patients in Shanghai is not optimistic, in which the frequency of SMBG is relatively low. It is of great importance to increase the frequency of SMBG in controlling blood glucose levels.
