Patterns of contact with hospital for children with an autism spectrum disorder: a Danish register-based study.
Danish kids with ASD visit hospital almost twice as often for every cause, so any single ‘ASD-illness link’ needs a second look for simple over-counting.
01Research in Context
What this study did
Atladóttir et al. (2012) pulled every Danish birth record from 1994-2004. They followed 1.2 million kids, including 9,600 with autism, for up to 15 years.
They counted every hospital stay, ER visit, and outpatient clinic contact. Then they compared kids with ASD to kids without ASD for each cause of admission.
What they found
Children with ASD had higher hospital rates for almost every diagnosis. The excess was not small: 40-100 % more contacts for infections, injuries, epilepsy, even acne.
The pattern looked global, not tied to one body system. The authors warned that this broad bump could make future studies over-link ASD to single diseases.
How this fits with other research
Liu et al. (2017) extends the same story to U.S. teens. They saw four-times higher ER use in ASD youth, especially rural and older girls. The climb started right where the Danish study ended.
Faso et al. (2016) drilled into one slice—ear infections. Kids with ASD had double the otitis media surgeries, proving the global excess contains real, specific needs.
Kaiser et al. (2022) pooled data and found ASD raises later bowel disease risk 1.5-fold. Without Osk’s warning, one might think ASD causes IBD; instead, ASD kids simply touch the system more, so they are spotted more.
Why it matters
When you read the next headline linking ASD to a new illness, ask: ‘Higher contact or true risk?’ Schedule routine ear, bowel, and epilepsy checks, but don’t over-pathologize. Use the excess contact as a chance to teach families when to stay home, when to call you, and when to head to hospital—saving stress and beds for those who really need them.

03Original abstract
The aim of this study was to study patterns of contact with hospital for children with autism spectrum disorder (ASD) using Danish population based register data. We included all children born in Denmark from 1994 through 2002. We found that children diagnosed with ASD had an increased rate of contact with hospital, almost regardless of the cause for the hospital contact. Given the overall association between hospital contact for various causes and ASD observed in these data, hospital data should be used cautiously in future studies searching for associations between a specific disease and ASD. If the increased rate of hospital contact overall for children with ASD is not considered, then misleading over interpretations might be made of observed associations between specific diseases and ASD.
