Children with an autism spectrum disorder may be at greater risk for contemplating suicide or attempting suicide than children without autism, according to Penn State College of Medicine researchers.
"We were looking at suicidal ideation and suicide attempts among children with autism versus those that didn't have autism," said Angela Gorman, assistant professor of child psychiatry, Penn State College of Medicine. "What we found is that there were some risk factors that were much more greatly associated with suicidal ideation and suicide attempts than others."
The research is the first large-scale, broad age and IQ range study that uses data provided by parents to analyze the rates of suicide contemplation and attempts in children with autism.
Gorman, along with Professor of Psychiatry Susan Dickerson Mayes, Assistant Professor Jolene Hillwig-Garcia and Associate Professor Ehsan Syed, analyzed data provided by parents of 791 children with autism, 186 typical children and 35 non-autistic depressed children between one and 16 years of age. The researchers looked at achievement and cognitive ability, as well as various demographic variables. The four most significant demographic variables were Black or Hispanic, 10 years old or older, socioeconomic status and male. The results were published in the January issue of Research in Autism Spectrum Disorders.
The researchers found that the percentage of children with autism rated by their parents as sometimes to very often contemplating or attempting suicide was 28 times greater than that of typical children, though three times less than that of depressed non-autistic children. The four demographic variables were significant risk factors, as well.
"That was probably the most important piece of the study," said Gorman. "If you fell into any of those categories and were rated to be autistic by a parent, the more categories you were a part of increased your chances for experiencing suicida
