Contribution of structured self-monitoring of blood glucose to self-efficacy in poorly controlled diabetes patients in China

Abstract

Aim: To investigate the association between structured self-monitoring of blood glucose (SMBG) and diabetes self-efficacy in Chinese patients. Methods: This study was a single-centre, open-label, prospective, randomized controlled trial. A total of 250 type 1 and type 2 diabetes patients were recruited and randomly assigned to the structured SMBG group and the control group in a 1:1 ratio. The main outcome observed in this subgroup analysis was a change in the diabetes self-efficacy scale (DSES) scores. A multivariate generalized estimating equation was used to evaluate factors affecting the DSES scores. Results: We found that the DSES scores tended to decrease significantly with the follow-up time in the intervention group (Wald β = 7.882, P
