A Two-Part Intervention to Target Cardiovascular Health

June 22, 2026 updated by: Alice Kuo, MD, PhD, MBA, University of California, Los Angeles

Autism Research Consortium on Physical Health: A Two-Part Intervention to Target Cardiovascular Health

Obesity is one of the most common health conditions among autistic young people and its prevalence rises at faster rates for autistic-relative to non-autistic-individuals. This places them at heightened risk for cardiovascular disease (CVD) and mortality before they enter adulthood. Studies have identified three key contributing factors to CVD outcomes in autistic individuals: unhealthy lifestyle behaviors, Adverse Childhood Experiences (ACEs), and chronic stress.

This study will explore the effectiveness of two CVD-focused primary care interventions for autistic individuals (ages 9-26): (1) lifestyle medicine consultations tailored towards supporting health-promoting behaviors; and (2) a Cognitive Behavioral Therapy (CBT) intervention tailored towards addressing chronic stress that contributes to excess weight and maladaptive eating behaviors and results in obesity and CVD. Participants and their caregivers will be randomly placed into either the Lifestyle Medicine Group, CBT Group, or combined Lifestyle Medicine with CBT Group. Participants will respond to questionnaires and surveys measuring lifestyle habits, stress, and psychological risk factors at their first visit, 6-month visit, and 3 months post-intervention visit. Over the course of 6 months, participants will attend virtual sessions (up to three times a month) in accordance with their intervention group.

Study Overview

Detailed Description

Autistic individuals experience almost three times the mortality rate relative to non-autistic populations, and are disproportionately likely to experience obesity-with increasing rates beginning in childhood and adolescence-relative to both the general population and those with other developmental conditions. Obesity is one of the most common health conditions among autistic young people and its prevalence rises at faster rates for autistic-relative to non-autistic-individuals. This places them at heightened risk for cardiovascular disease (CVD) and mortality before they enter adulthood.

Studies have identified three key contributing factors to CVD outcomes in autistic individuals: unhealthy lifestyle behaviors, Adverse Childhood Experiences (ACEs), and chronic stress. Taken together, this study addresses a critical gap in the field: lack of appropriate and effective healthcare/lifestyle interventions for autistic individuals with CVD and/or experiences of chronic stress that lead to obesity and poor cardiovascular health. These efforts require dedicated interventions selected for their impact on two key mechanisms underlying obesity and CVD: lifestyle and ACEs/chronic stress.

This study will explore the effectiveness of two CVD-focused primary care interventions for autistic individuals (ages 9-26): (1) lifestyle medicine consultations tailored towards supporting health-promoting behaviors; and (2) a Cognitive Behavioral Therapy (CBT) intervention tailored towards addressing chronic stress that contributes to excess weight and maladaptive eating behaviors and results in obesity and CVD. Participants and their caregivers will be randomly placed into either the Lifestyle Medicine Group, CBT Group, or combined Lifestyle Medicine with CBT Group. Participants will respond to questionnaires and surveys measuring lifestyle habits, stress, and psychological risk factors at their first visit, 6-month visit, and 3 months post-intervention visit. Over the course of 6 months, participants will attend virtual sessions (up to three times a month) in accordance with their intervention group.
