The relationship between autism and obesity is an area of growing concern. Understanding this connection is crucial for parents and caregivers of individuals with autism, as well as for those interested in autism spectrum disorder.
According to research conducted by the U.S. Centers for Disease Control, nearly a third of autistic children are severely overweight, in stark contrast to only 13 percent of typically developing children.
In adults with autism, the prevalence of overweight and obesity is also notable. Estimates indicate that 28% of autistic adults are classified as overweight (BMI 25–29.9 kg/m²), while 35% fall into the obesity category (≥30 kg/m²).
Additionally, 11% of this population experiences hypertension. These prevalence rates align closely with those in the general U.S. population, where 64% of males and 61% of females have a BMI ≥25 kg/m².
Factors Contributing to Obesity in Autism
Several factors contribute to the increased rates of obesity among individuals with autism.
One significant factor is the tendency for less physical activity. Many children with autism may engage in less physical exercise, which can lead to weight gain.
Poor nutrition is another contributing factor. Children with autism may have specific dietary preferences or aversions that limit their nutritional intake, leading to unhealthy eating habits. Additionally, certain behavioral medications prescribed for managing autism symptoms can have weight gain as a side effect.
Sleep disturbances are also prevalent in children with autism. Sleep deprivation can lead to hormonal changes in the brain that diminish hunger awareness, potentially exacerbating weight gain issues. This is particularly concerning for children with autism, who may already struggle with sleep-related challenges.
According to the U.S. Centers for Disease Control, nearly 1/3 of autistic children are severely overweight, compared to only 13 percent of typically developing children. This disparity highlights the need for awareness regarding the health risks associated with obesity in this population.
Children with autism who are overweight may have a body mass index (BMI) above the 99th percentile for their age. This elevated BMI can lead to serious weight-related medical issues, affecting vital organs such as the heart, lungs, and liver.
Additionally, sleep disturbances are common in children with autism, and sleep deprivation can increase the production of brain hormones that diminish hunger awareness. This can exacerbate weight-related concerns, making it crucial to address both sleep and nutrition.
Maternal Obesity and Risk
Maternal obesity plays a significant role in the health outcomes of children, particularly concerning neuropsychiatric disorders such as autism spectrum disorder. Understanding this connection is crucial for parents and caregivers.
Children born to mothers with obesity, both before and during pregnancy, face an increased risk of developing neuropsychiatric and behavioral conditions.
A meta-analysis of over 3.6 million mother-child pairs showed that maternal pre-conception obesity is linked to a heightened risk of conditions such as ADHD, autism, conduct disorder, and psychotic disorder.
The findings indicate a 30% increased risk of peer relationship problems in children of mothers with obesity. This highlights the importance of maternal health prior to and during pregnancy, as it can have lasting effects on a child’s mental health and behavior.
Given the strong association between maternal obesity and the risk of neuropsychiatric disorders in children, effective weight management strategies before and during pregnancy are essential.
Maternal obesity has been linked to various adverse perinatal outcomes, including preterm birth, low birthweight, stillbirth, and macrosomia (high birthweight).
Interventions targeting maternal weight management can help mitigate these risks. Encouraging healthy lifestyle choices, such as balanced nutrition and regular physical activity, can contribute to better health outcomes for both mothers and their children.
The results underscore the need for healthcare providers to prioritize maternal health and provide resources for weight management, ultimately aiming to reduce the incidence of autism and other behavioral disorders linked to obesity.
Addressing Weight Concerns in Autism
Children with autism may exhibit poor nutrition and reduced physical activity, both of which contribute to weight gain. Sleep deprivation can exacerbate these issues, as it increases the production of brain hormones that diminish hunger awareness. This is particularly concerning for children with autism, who may already experience sleep disturbances.
To effectively address these weight concerns, a multi-faceted approach is essential. Families should be encouraged to engage in regular physical activities that are enjoyable for their children.
Additionally, promoting healthy eating habits through education and support can help improve nutrition.
Management strategies for weight-related issues in children with autism should involve a comprehensive care team. This team may include a physician, specialty nurse, dietitian, physical activity specialist, and psychologist. Such a collaborative approach ensures that all aspects of the child’s health and well-being are considered.
Interventions may include:
Findings from studies emphasize the importance of targeting maternal weight management before and during pregnancy. This proactive approach can help mitigate the risks of neuropsychiatric and behavioral disorders in children, ultimately contributing to better health outcomes for those with autism.

Final Thoughts
Obesity and autism are both complex conditions, and while research suggests a possible link, it’s important to approach the topic with care. Correlation does not always mean causation, and many factors play a role in both conditions. Instead of jumping to conclusions, more research is needed to understand the connection fully.
