Brief report: bone fractures in children and adults with autism spectrum disorders.

The team pulled U.S. emergency-department records for 3- to young learners. They compared fracture odds between people with and without autism.

Over one million visits were scanned. Hip, forearm, and spine breaks were counted.

Kids and adults with ASD had higher odds of hip fractures at every age. The jump was starkest in females, who also showed more forearm and spine breaks.

The fracture signal was not tiny: hip-break odds were roughly double for the ASD group.

Barnhill et al. (2017) helps explain why. They measured actual bone density in 4- to young learners boys with ASD and found their spines were significantly less dense than typical peers, even when diet and vitamins were fine. Lower density plus active kids can equal more breaks.

Kaiser et al. (2022) zoom out. Their meta-analysis shows kids with ASD also face higher odds of inflammatory bowel disease. Gut trouble can limit nutrient uptake, another path to weaker bones. Together the papers paint a picture of wider medical vulnerability, not just clumsiness.

Atladóttir et al. (2012) add a caution. Danish registers show children with ASD visit hospital for almost every diagnosis more often. So part of the fracture count could reflect greater health-care contact, not only weaker bones. Even with that bias, the hip-fracture spike stayed large, making the finding more convincing.

If you serve clients with ASD, add bone health to your checklist. Ask about past fractures, note any limp or pain, and prompt parents to request a DEXA scan if the child has frequent spills. For adult women on your caseload, recommend calcium and vitamin D discussion with their physician. Catching weak bones early can spare painful breaks and lost therapy days.
