Effects of Online Diabetes Self-management Education on Knowledge Retention, BMI, and HbA1c in Newly Diagnosed Adults With Type 2 Diabetes
Effects of Online Diabetes Self-management Education on Knowledge Retention, BMI, and HbA1c in Newly Diagnosed Adults With Type 2 Diabetes: a Quasi-experimental Study
Source: ClinicalTrials.gov · Last updated 8 Jul 2026
Brief summary (registry, in English)
Type 2 diabetes requires active self-management from the time of diagnosis, but participation in traditional face-to-face diabetes self-management education is often limited by access-related and personal barriers. Online education may provide a more flexible and accessible way to deliver structured diabetes education, particularly for newly diagnosed adults who need timely support in understanding and managing their condition. This study evaluated the effects of online diabetes self-management education compared with traditional face-to-face education on diabetes knowledge retention, body mass index (BMI), and HbA1c in adults newly diagnosed with type 2 diabetes who were not receiving antidiabetic medication. A total of 123 participants were included: 49 participants received online diabetes self-management education, 52 participants received traditional face-to-face education, and 22 participants who declined education formed a non-randomized control group. Diabetes knowledge was assessed at baseline, immediately after the intervention, and at three-month follow-up, while BMI and HbA1c were measured at baseline and follow-up. At three-month follow-up, both online and traditional education groups showed significantly greater diabetes knowledge compared with the control group. The online education group also showed better immediate post-intervention knowledge than the traditional education group. Both education groups had significant reductions in BMI from baseline to follow-up, while no significant short-term effect on HbA1c was observed.
