Objective  To assess the effect of metformin combined with family information-motivation-behavior model intervention on the long-term efficacy of patients with type 2 diabetes.

Methods  A retrospective analysis was conducted on data from type 2 diabetes patients treated at the 903rd Hospital of the Joint Logistic Support Force of the People's Liberation Army of China from January 2021 to December 2022. Patients were divided into the control group and the test group based on the intervention protocol. The control group received metformin treatment combined with conventional outpatient interventions, while the test group received metformin treatment combined with a family information-motivation-behavior model intervention. The blood glucose and lipid-related indicators of the two groups were compared before and 3, 6, and 12 months after intervention. The disease awareness, treatment compliance, quality of life, and intervention satisfaction were also compared between the two groups 12 months after intervention.

Results  A total of 159 patients were included in the study, with 87 in the control group and 72 in the test group. Compared with baseline, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hPBG), glycated hemoglobin (HbA1c), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and total cholesterol (TC) were significantly reduced at 3, 6, and 12 months after treatment in both groups, with the test group showing lower levels than the control group (P<0.05). Treatment compliance and disease awareness were significantly higher in the test group compared to the control group (P<0.05). Following intervention, the quality of life and intervention satisfaction were significantly higher in the test group compared to the control group (P<0.05).

Conclusion  Metformin combined with information-motivation-behavioral model intervention effectively controls blood glucose levels in patients with type 2 diabetes, improving patient quality of life and satisfaction.
