Brief Summary:
Transgender and gender-diverse adolescents are at increased risk for obesity, disordered eating behaviors, body dissatisfaction, and reduced quality of life due to minority stress and structural inequities. However, no structured lifestyle interventions specifically tailored to this population have been developed.
This randomized controlled trial aims to evaluate the effectiveness of a 6-month interdisciplinary lifestyle intervention designed to prevent obesity and eating disorders in transgender and gender-diverse adolescents aged 10-14 years. Participants will be randomized (1:1) to either an intervention group receiving monthly group sessions (for adolescents and caregivers separately) and weekly supportive messages, or a control group receiving standard outpatient care and general health recommendations.
The primary outcome is quality of life measured by the WHOQOL-BREF. Secondary outcomes include eating disorder symptoms, body image, diet quality, physical activity levels, sedentary behavior, body composition, and anthropometric measures.
Detailed Description:
This study is a parallel-group randomized controlled trial conducted at the Lifestyle Medicine Center, Faculty of Medicine, University of São Paulo (FMUSP), Brazil.
Participants will be recruited from the Gender Identity and Sexual Orientation Outpatient Clinic (AMTIGOS) at the Institute of Psychiatry, Hospital das Clínicas, University of São Paulo. Eligible transgender and gender-diverse adolescents aged 10 to 14 years receiving care at AMTIGOS will be invited to participate.
After baseline assessments, participants will be randomly assigned (1:1), in blocks of six, to either:
1. an interdisciplinary lifestyle intervention plus usual outpatient care; or
2. usual outpatient care plus a single session of general health recommendations.
The 6-month intervention is grounded in Social Cognitive Theory and incorporates gender-affirmative principles and an intersectional framework. The intervention includes:
* Monthly group sessions for adolescents
* Monthly educational group sessions for caregivers
* Weekly reinforcement messages
The program focuses on promoting healthy eating behaviors, increasing physical activity, reducing sedentary behavior, preventing unhealthy weight-control practices, and fostering positive body image and body appreciation.
The control group will receive standard outpatient follow-up at AMTIGOS and a single individual session including general recommendations regarding healthy eating, physical activity, body acceptance, and avoidance of unhealthy weight-control behaviors.
Outcomes will be assessed at baseline and after 6 months. The primary outcome is quality of life measured by the WHOQOL-BREF. Secondary outcomes include eating disorder symptoms, body image, dietary quality, physical activity, sedentary behavior, body composition, and anthropometric measures.
