Suicide rates among all US children ages 10-14 years tripled between 2007 and 2021, becoming the second leading cause of death for this age bracket. Between 2018 and 2021, 315 suicides were reported among US children ages 5 to 11 years.
People with ASD show increased rates of STB, although prevalence estimates vary by study, which led the authors to study the issue.
Lead author Benjamin Joffe Schindel, MD, MPH, a fellow in neurodevelopmental medicine at the Kennedy Krieger Institute in Columbia, Maryland, and colleagues, analyzed responses from 968 caregivers of children ages 8-25 with ASD.
They found the following reported lifetime STB incidence:
- 392 (40.5%) reported wanting to die
- 187 (19.3%) reported wanting to end their own lives
- 72 (7.4%) reported having a suicide plan
Among those answering affirmatively to each of the above questions regarding STB, onset at 8 years or younger was reported in 142 (36.2%); 66 (35.3%); and 13 (18.1%) of the children, respectively. Included in the findings was one suicide attempt by cutting in an 8-year-old child.
Dr. Schindel said though there is no direct comparison with age of these thoughts among the general population, a previous study in 2013 showed that through age 10 prevalence of suicide ideation is very low (< 1%), then increases slowly through age 12 and then more rapidly until age 17.
Disturbing Findings
“The unexpectedly high frequency of STBs among children with ASD who were 8 years or younger is particularly disturbing given the lack of validated suicide risk screening tools and interventions for this age group,” the authors wrote. They added that early start of STB in children with ASD is important as this population has been underrepresented in suicide research and prevention efforts.
The average child age in this study was 13.4; 84.8% were White; and 81% were male. More than half of the children (54.8%) were taking medications for emotional, behavioral, or mood-related issues.
Data were collected from May to October 2017 from responses to the Mental Health and Suicidal Behaviors Questionnaire, an online caregiver-answered survey. The survey was created and distributed by the Interactive Autism Network (IAN), an international autism registry, from 2006 to 2019 with approximately 55, 000 participating families.
Thoughts Come at a ‘Shockingly Young Age’
Suzanne Rybczynski, MD, chief medical officer at East Tennessee Children’s Hospital in Knoxville, who was not part of the research, said the study was small but will help get the message out that “kids start thinking about suicide, especially kids with autism,” at a “shockingly young age.”
The results demonstrate the great demand for studying thoughts and behaviors especially in younger children and in children with neurodiversity — autism or other neurodevelopmental disabilities.
Studying children with ASD in relation to suicidal thoughts is difficult, Dr. Rybczynski said, because the way they think about death and how much is understood about the finality of suicide has not been well studied. It’s also uncertain how well the children understood the questions in this study, she added.
This retrospective study also asked for responses from caregivers who may remember or interpret a child’s thoughts and words differently from the child’s true intent, Dr. Rybczynski said.
“We need more studies like this asking questions to kids directly,” she said, so researchers can figure what children think it means to die.
