Piloting a Biofeedback Intervention for Adolescents With Overweight and a History of Adverse Childhood Experiences

Overview

Adverse childhood experiences (ACEs), referring to traumatic experiences occurring before 18 years of age (e.g., abuse/neglect), are associated with a 30-70% increased risk of developing adolescent and adult obesity and obesity-related cardiometabolic comorbidities, which may be due to dysregulation in stress-related physiology and engagement in stress-related behaviors. While adolescents with ACEs have a 2.25 times increased risk of obesity, standard-of-care lifestyle (e.g., nutrition/physical activity) interventions do not typically incorporate trauma-informed care, including assessment and therapeutic attention to effects of ACEs. Heart rate variability (HRV) biofeedback is an evidence-based, relatively brief, mind-body intervention targeting the stress physiology that can be dysregulated in adolescents with ACEs. The objective of this proposal is to adapt and test a 4-session HRV biofeedback protocol for 12-17-year-olds with BMI\>85th percentile and ACEs. First (Phase 1), we will iteratively adapt a 4-session HRV biofeedback facilitator protocol with n=3-5 adolescents with overweight/obesity and ACEs, using adolescent quantitative and qualitative feedback to hone and optimize HRV biofeedback for this population (Aim 1). Next (Phase 2), we will conduct a randomized waitlist-controlled pilot study of n=30 adolescents with overweight/obesity and ACEs to assess acceptability and feasibility (Aim 2) and to describe changes in theorized targets of biofeedback (Aim 3).
