"Rates of death are higher for autistic individuals compared to the general population"

It's world autism awareness day today (2 April). The theme this year (2019), according to the United Nations, is "Assistive Technologies, Active Participation", something rather timely given the recent realisation that quite a few people diagnosed with autism are not properly represented [1] in various fields. Indeed, it continues a theme on the under-represented and under-studied populations within the autism spectrum being highlighted today of all days (see here)...

To mark this years autism awareness day, I'm turning to a topic that is probably about as important as it gets with regards to autism or any label: premature death. Specifically, highlighting how premature premature death can actually be when autism is diagnosed. I appreciate that this is not great PR for autism. But it's real-life for too many; and needs to be talked about as much as possible so people sit up and (hopefully) do something about it...


The quote heading up this post - "Rates of death are higher for autistic individuals compared to the general population" - taken from the findings reported by Ye In (Jane) Hwang and colleagues [2] is perhaps not altogether accurate. A more precise meaning is required: as a group, those diagnosed with autism or autism spectrum disorder (ASD) are at some elevated risk for a premature (untimely) death than the non-autistic population (see here). Not exactly great dinner party conversation but vitally important nonetheless.

This is a topic that has cropped up time and time again in the peer-reviewed research literature and beyond (see here and see here). The grim trend crosses geographical boundaries and seems to cover the entirety of the autism spectrum. This time around New South Wales in Australia provided the source data with the aim "to report the rates and risk factors for mortality and cause of death in individuals on the autism spectrum (n = 35,929 age range 5-64) with and without concurrent intellectual disability (ID)."

The results: "Mortality rates for those on the autism spectrum were 2.06 times that of the general population." In line with other data (see here), those who also presented with intellectual (learning) disability alongside autism were at a higher risk of death. Epilepsy is also reported as being an important issue too (see here). A few other details are highlighted in the Hwang paper including the observations that "injury and poisoning" were some of the top-ranked causes of death as per other data (see here and see here).

What's more to say on this topic? Another call to action (see here)? Some more big news headlines (see here)? Another 'long-term plan' (see here)? All well-and-good, but what's actually being done to tackle such frightening statistics here and now and actually improve and extend lives in the here and now? What's currently helping autistic people to 'age well' [3]? And just in case you're of the inclination that epilepsy and intellectual (learning) disability are some how not a 'core' part of some autism, you're probably wrong in many cases (see here and see here)...

If the Hwang and other data aren't enough to satisfy you on this topic, another research paper with another (similar) set of grim findings has also recently been published [4]. Faced with such data, discussions about a puppet depicting one face of autism (see here) for example, don't seem all that important do they? Indeed, if half as much time was dedicated to highlighting the mortality stats associated with autism and making sure this makes headlines - over a 20 year period "6.4% of individuals died at an average age of 39 years" - may be more would be done to tackle them, including providing "adequate access to health care for individuals with autism spectrum disorder."

Food for thought, and hopefully important fuel for action...
