The Association Between Obesity and Key Health or Psychosocial Outcomes Among Autistic Adults: A Systematic Review.
Obesity raises risk of in-hospital death and chronic disease in autistic adults—screen BMI and refer to weight-management programs.
01Research in Context
What this study did
Gilmore et al. (2022) pooled every paper they could find on body weight and health in autistic adults.
They looked only at studies that measured obesity and also tracked things like hospital deaths, diabetes, or heart disease.
Four studies made the cut; together they painted the first big picture of how extra weight shapes adult health in ASD.
What they found
Across the four studies, obese autistic adults were more likely to die while in the hospital.
They also carried more long-term illnesses such as high blood pressure and diabetes.
The review did not give exact numbers, but the pattern held steady in every paper checked.
How this fits with other research
Granich et al. (2016) and Healy et al. (2019) showed that autistic youth are already heavier than peers.
Brodhead et al. (2019) added that heavier autistic kids and adults move less, setting the stage for later problems.
The 2022 review now extends those youth findings into adulthood, linking the same extra pounds to real medical danger.
Why it matters
If you serve autistic teens or adults, weigh them and plot BMI at every visit.
A high number is your cue to refer to weight-management or exercise programs before chronic disease or hospital risk grows.

03Original abstract
Obesity is linked with health and psychosocial outcomes among many populations. However, it is unclear the extent to which obesity is linked with these outcomes among autistic adults. We searched seven research databases for articles examining the association between obesity and autistic adults' health and psychosocial outcomes. Three studies found that obesity was associated with health outcomes, including: in-hospital mortality, risk of type II diabetes, cardiovascular disease, and number of co-occurring medical conditions. One study found no significant association between autism diagnosis, mental health conditions, and body mass index. Obesity increases the risk of in-hospital mortality and some chronic conditions among autistic adults, highlighting the need for clinicians trained to promote weight management among autistic adults.
