Behavioral Weight Loss Intervention Preferences of Adolescents with Overweight/Obesity

Behavioral lifestyle interventions are the foundation of adolescent obesity treatment. Tailoring an intervention using adolescent stakeholder engagement during the development process could improve intervention effectiveness. Adolescents with overweight/obesity ages 14-19 (n = 41) participated in 11 sex-specific focus groups (girls = 6, boys = 5) and were asked their preferences regarding who should lead the intervention and be involved, what the messaging of the program should be, how to make the program engaging and maintain participation, and how to best measure nutrition intake and activity. Transcripts were coded and analyzed for emergent themes. Mean age was 16.0 ± 1.8 years and participants were racially/ethnically diverse. Adolescents preferred interventions that avoid a focus on "weight loss," and instead emphasize "healthy lifestyle," which represents a more comprehensive goal of targeting physical and mental well-being. Most participants indicated preferences for a relatable instructor with prior weight loss experience. Both sexes preferred optional parental involvement, as some parents were described as helpful, while others were perceived as a hindrance to success. Boys and girls identified incentives, engaging activities, and electronic communication as core components for engagement and retention, with girls emphasizing socialization and building relationships. Sex differences in preferences were observed. Girls had more concerns about intervention participation and preferred interventions to be sex stratified. Behavioral interventions to treat adolescent obesity should focus messaging/content on healthy lifestyles, rather than weight loss, and be sex stratified. Development and implementation of future behavioral interventions for adolescent obesity should consider tailoring to adolescent preferences when possible to improve feasibility, acceptability, and effectiveness.
