TEENFIT: A Self-Management Health Program for Adolescents with Obesity – Study Protocol and Pilot Study Findings

Introduction: Childhood obesity represents a significant global public health challenge, associated with a multitude of severe comorbidities that impact various physiological and mental systems. This study describes the TeenFit program, an interdisciplinary intervention focused on health self-management for adolescents with obesity and presents the findings of its pilot study. Methods: The TeenFit program was developed using self-determination theory, self-regulation, and the COM-B model. The study sample comprised seven adolescents aged 12 to 14, representing the upper 95th percentile of BMI for age and sex. This intervention was delivered by an interdisciplinary team of medical doctors, nutritionists, psychologists, and exercise physiologists. The program's duration was established at six months, incorporating two theoretical and practical exercise sessions each week and monthly workshops designed for the participant's parents. Data collection occurred at the three-month mark of the intervention. Results: The satisfaction levels reported by participants and their guardians were markedly high, underscoring the critical importance of multidisciplinary approaches and the consistent frequency of the sessions. Identified facilitators, the adaptability of the session structures, the positive dynamics within the group, and the supportive involvement of parents. Conversely, the primary barriers encountered pertained to logistical challenges and communication issues. Conclusions: The findings suggest that implementing interventions aimed at health self-management is feasible and well-accepted among adolescents with obesity, demonstrating the potential to facilitate substantial and enduring behavioral changes. The effectiveness of this intervention warrants evaluation through a randomized controlled trial.
