Effectiveness of a Community-Based Health Care Program on Glycemic Control Among Patients with Uncontrolled Type 2 Diabetes Mellitus: A Quasi-Experimental Study

Year: 2026

Type: article

Abstract: Background: Type 2 diabetes mellitus (T2DM) is a major public health problem in Thailand, particularly in rural areas where individuals have limited access to structured diabetes care and education. Poor self-management contributes to uncontrolled glycemic levels and long-term complications. Objectives: This study evaluated the effectiveness of a community-based health care program on glycemic control and self-care behaviors among adults with uncontrolled T2DM. Methods: A quasi-experimental study was conducted among 80 patients with uncontrolled T2DM in Kalasin Province. Participants were assigned to either an intervention group (n = 40) or a comparison group (n = 40). The 12-week intervention consisted of diabetes self-management education, individualized lifestyle support, and community/family engagement. Diabetes self-care behavior and glycated hemoglobin (HbA1c) were assessed at baseline and Week 12. Statistical analyses included paired t-test, independent t-test, and 95% confidence intervals. Results: The intervention group demonstrated a significant improvement in self-care behavior (MD = 14.83; p < 0.0001), compared with a minimal change in the comparison group (0.80; p = 0.756). HbA1c levels significantly decreased in the intervention group (−0.47%; 95% CI: −0.61 to −0.33; p < 0.0001), while a slight nonsignificant increase was observed in the comparison group (0.11%; p = 0.210). The between-group analysis showed a significant reduction in HbA1c favoring the intervention (−0.92%; p < 0.0001), supported by a large effect size (Hedges’ g = 0.87). Conclusions: This community-based health care program effectively enhanced diabetes self-management behaviors and improved glycemic control. Integrating such behavioral support into primary health care services may strengthen long-term diabetes management and reduce complications among patients with uncontrolled T2DM.
