Effectiveness of a Telemedicine-Based Intervention for Childhood Obesity Management: A Randomized Controlled Trial

Telemedicine can address access barriers in childhood obesity management by supporting continuity of care and caregiver engagement. This randomized controlled trial compared a telemedicine-based program with guideline-based usual care among 70 children with obesity (aged 5–15 years) and their caregivers, randomized to telemedicine (n = 35) or usual care (n = 35) for 6 months. The telemedicine program included online consultations, digital caregiver education, remote monitoring, and secure messaging via the SUTH application integrated with the hospital information system. The control group received standard outpatient care with routine counseling and printed materials; baseline characteristics were similar between groups. Baseline demographic and clinical characteristics were comparable between groups. After 6 months, both groups showed modest reductions in BMI; however, ANCOVA-adjusted analyses indicated no significant between-group difference in post-intervention BMI. Weight-for-height decreased in both groups, with a slightly greater percentage reduction in the telemedicine group. Caregiver satisfaction and knowledge were significantly higher in the telemedicine group at follow-up (all p < 0.01; knowledge p < 0.001). These findings suggest that telemedicine-based care may contribute to modest improvements in anthropometric outcomes while substantially enhancing caregiver knowledge and healthcare service satisfaction, supporting its role as a scalable adjunct in pediatric obesity management.
