🧠 AI Summary:
New research from the American Heart Association and Autism Speaks reveals that autistic people face significantly higher risks for heart disease, high blood pressure, and diabetes compared to the general population. A joint fellowship program is now funding researchers to close critical gaps in cardiovascular care for the autism community. This blog breaks down what the research means, why it matters, and how families raising children with autism can take a proactive whole-child approach to long-term health.
Autism and Heart Health: What New Research Means for Your Child’s Long-Term Wellbeing
There is a conversation happening in the medical research community right now — one that every parent raising a child with autism deserves to be part of.
For years, the focus of autism research has centered on behavior, communication, and learning. And rightfully so — those areas shape how children grow, connect, and thrive. But a growing body of evidence is pointing to something that has been quietly overlooked: children and adults on the autism spectrum may face a significantly higher risk for cardiovascular and metabolic health problems than the general population.
Heart disease. High blood pressure. Diabetes. These are not conditions most parents associate with a childhood autism diagnosis. But researchers are now saying they should be on every family’s radar — and they are putting serious funding behind finding out why.
This post breaks down the latest research, what it means for your family, and how a whole-child approach to care — including ABA therapy — plays a role in your child’s long-term health and wellbeing.
What the New Research Is Saying
The American Heart Association and Autism Speaks Are Joining Forces
In a landmark collaboration, the American Heart Association (AHA) and Autism Speaks have announced a joint fellowship program funding predoctoral and postdoctoral researchers who are studying the connections between autism and cardiovascular and brain health. The initiative — which includes 2027 fellowship awards — is part of a broader, multi-million dollar effort to address what researchers are calling a critical and underserved area of autism health care.
The goal is not just discovery. A key emphasis of this program is implementation science — the study of how evidence-based approaches can be translated into real-world care, in clinics and communities where families actually are. Because knowing something works in a lab is not enough. Families need that knowledge to reach their child’s pediatrician, their school team, and their therapy providers.
What the Studies Are Finding
There The research connecting autism to cardiovascular risk is not brand new — but it is accelerating. A 2023 review of studies published in JAMA Pediatrics found that people with autism have a higher risk of developing cardiometabolic diseases. Additional studies have consistently identified elevated rates of high blood pressure, obesity, and type 2 diabetes in autistic individuals compared to neurotypical peers.
Here is a snapshot of what the emerging research shows:
- Autistic people are significantly more likely to experience heart disease and high blood pressure than the general public.
- Cardiometabolic conditions — including obesity, insulin resistance, and metabolic syndrome — appear at higher rates in the autism community.
- Cerebrovascular health, which includes brain blood flow and stroke risk, is also an area of growing concern.
- Despite these elevated risks, autistic individuals are less likely to receive adequate cardiovascular screening and preventive care.
- There are significant health equity gaps — meaning autistic people do not always have access to the same quality of cardiovascular care as the rest of the population.
These are not small statistics. They represent real families, real children, and real futures that depend on the medical community catching up to what the data is showing.
Why Are Autistic People at Higher Risk?
Researchers are still working to fully understand the mechanisms, but several factors may contribute to the elevated cardiovascular risk in autistic individuals:
- Sedentary behavior — many autistic children and adults engage in less physical activity due to sensory sensitivities, social barriers, or limited access to inclusive recreational programs.
- Dietary patterns — food selectivity is extremely common in autism and can lead to nutritional imbalances that affect metabolic health over time.
- Sleep disruption — sleep problems affect up to 80% of autistic children, and chronic poor sleep is a well-established risk factor for cardiovascular disease.
- Chronic stress and anxiety — high rates of anxiety in autism may contribute to elevated cortisol levels and long-term cardiovascular strain.
- Medication effects — some medications used to manage co-occurring conditions in autism, including certain antipsychotics, carry known metabolic side effects.
- Barriers to care — communication differences, sensory sensitivities in clinical settings, and lack of provider training can all make it harder for autistic individuals to access consistent healthcare.
Understanding these pathways is exactly what the AHA and Autism Speaks fellowships are designed to investigate — so that interventions can be developed that actually work for autistic people and their families.
What This Means for Parents of Young Children with Autism
If your child was recently diagnosed with autism — or has been receiving services for years — you may be wondering what this research means for you right now. Here is what we would encourage every autism family to consider.
Start the Conversation with Your Pediatrician Early
Cardiovascular health is not just an adult concern. The habits, patterns, and health markers established in childhood lay the foundation for lifetime health. That means now is the time to talk to your child’s pediatrician about:
- Blood pressure monitoring at well-child visits
- Cholesterol and blood sugar baseline levels, especially if there is a family history of heart disease or diabetes
- Weight and BMI trends over time, without stigma or shame — just information
- Sleep health and whether your child is getting adequate, quality rest
- Physical activity levels and any barriers to movement your child faces
You do not need to wait for a problem to appear. Proactive conversations with your child’s medical team are one of the most powerful things you can do.
Pay Attention to Diet — With Grace and Strategy
Food selectivity in autism is real, it is common, and it is not a parenting failure. Many children with autism have genuine sensory aversions to textures, temperatures, and flavors that make expanding their diet genuinely difficult. But over time, a highly restricted diet can affect metabolic health.
Some strategies that can help:
- Work with an occupational therapist who specializes in feeding therapy to gradually expand food acceptance.
- Focus on increasing fiber, vegetables, and whole grains rather than eliminating favorite foods entirely.
- Use positive reinforcement strategies — including ABA-based feeding programs — to build new food associations without pressure or force.
- Consult with a registered dietitian who has experience working with autistic children.
Small, sustainable changes over time make a far bigger difference than sudden dietary overhauls.
Prioritize Movement in Ways That Feel Good to Your Child
Exercise does not have to mean team sports or gym class. For many autistic children, movement looks different — and that is perfectly okay. What matters is that it is consistent and enjoyable.
- Sensory-friendly swimming, trampolining, cycling, and hiking are excellent options for many autistic children.
- Movement breaks built into the daily routine, even short ones, add up significantly over time.
- ABA therapy often incorporates movement and activity naturally into skill-building, play, and community-based learning.
The goal is not performance. It is building a body that stays healthy and a child who associates movement with joy — not obligation.
Take Sleep Seriously
If your child struggles with sleep — and many autistic children do — this is worth prioritizing, not just for their behavior and learning, but for their long-term cardiovascular health. Chronic sleep deprivation in childhood is linked to higher rates of obesity, hypertension, and metabolic dysfunction.
Talk to your child’s physician about sleep hygiene strategies, melatonin if appropriate, and any sensory or anxiety-related barriers to sleep your child may be experiencing. ABA therapy can also address bedtime routine behaviors directly and effectively.
The Whole-Child Approach: Why ABA Therapy Is Part of This Conversation
At first glance, ABA therapy and cardiovascular health might seem like an unlikely pairing. But they are more connected than most people realize.
ABA therapy — Applied Behavior Analysis — is the gold standard evidence-based treatment for autism. And while its most visible focus is on communication, behavior, and daily living skills, its impact extends far beyond those categories.
Here is how ABA therapy contributes to the kind of whole-child health that this research is calling for:
- Routine building — ABA helps children develop and maintain predictable daily routines, including consistent sleep schedules, mealtimes, and physical activity patterns. Routine is deeply protective for cardiovascular health.
- Stress and anxiety reduction — by teaching children functional communication and emotional regulation skills, ABA reduces the chronic stress load that contributes to cardiovascular risk over time.
- Feeding and dietary programs — Board Certified Behavior Analysts (BCBAs) and ABA therapists frequently work on food acceptance, expanding dietary variety in a gradual, positive, data-driven way.
- Physical activity integration — ABA therapy in natural environments often includes play-based and community-based activities that naturally incorporate movement.
- Independence and self-care — as children build independence in daily living skills, they become better equipped to participate in their own health care — understanding medical visits, communicating symptoms, and following health routines.
- Family education and support — ABA programs coach caregivers too, which means the healthy habits started in therapy can be reinforced at home every single day.
We see the whole child. Always.

Frequently Asked Questions
Q1: Should I be worried about my young child’s heart health if they have autism?
The research is not a reason to panic — it is a reason to be proactive. Most children with autism will not develop serious cardiovascular problems in childhood. But the patterns that lead to adult cardiovascular disease often begin early. Talking to your pediatrician about baseline health monitoring, sleep, diet, and physical activity now is a smart, informed step that costs nothing and could make a real difference over time.
Q2: Are the cardiovascular risks the same for all autistic people?
Not necessarily. The research suggests elevated risk across the autism spectrum, but the magnitude may vary based on individual factors including co-occurring conditions, medication use, diet, activity level, sleep quality, and access to healthcare. This is one of the reasons the AHA and Autism Speaks fellowships are so important — the more we understand individual risk factors, the better we can tailor prevention and care.
Q3: Can ABA therapy actually help with diet and physical activity?
Yes, absolutely. ABA therapy is a highly flexible, individualized approach that can address a wide range of behaviors — including feeding behaviors, activity avoidance, and daily health routines. Many ABA programs include specific protocols for food acceptance and physical activity engagement, particularly for children with significant sensory sensitivities or behavioral patterns that limit participation.
Q4: What is implementation science and why does it matter for autism families?
Implementation science is the study of how research findings can be effectively put into practice in real-world settings — clinics, schools, and communities. It matters because many excellent research discoveries never actually reach the people who need them. The AHA and Autism Speaks fellowship program’s emphasis on implementation science means the goal is not just to produce new knowledge, but to ensure that knowledge changes how autistic people are actually cared for. That is a meaningful commitment.
Q5: Where can I learn more about the AHA and Autism Speaks cardiovascular research initiative?
You can visit AutismSpeaks.org and the American Heart Association’s website at heart.org for the latest information on the fellowship program and related research. Your child’s pediatrician or developmental specialist may also be able to point you toward current clinical guidelines as they evolve.
At On Target ABA, we serve children ages 2–12 across Ohio and Utah, providing evidence-based ABA therapy that builds real skills in real places. Most insurance is accepted. If you have questions about how ABA therapy supports your child’s whole-child health and wellbeing, reach out to our team today — because every child deserves care that sees all of who they are.
