(Press-News.org) Toronto, ON, August 9, 2023 – Autistic females (assigned sex at birth) have an 83% increased risk of self-harm leading to emergency healthcare relative to non-autistic people, according to a new study from ICES and the Centre for Addiction and Mental Health (CAMH).
Autistic males also had a 47% greater risk of self-harm events and had the highest incidence of suicide death compared to autistic females and non-autistic individuals.
The study, “Self-Harm Events and Suicide Deaths Among Autistic Individuals in Ontario, Canada,” was published today in JAMA Network Open and is the first in Canada to explore suicide rates and self-harm events in autistic versus non-autistic individuals factoring sex, sociodemographic and clinical risk factors.
“The presence of psychiatric illnesses substantially accounts for these increased risks,” says lead author Meng-Chuan Lai, staff psychiatrist and senior scientist at CAMH. “We know that many self-harm and suicide-related events could be prevented when people have access to tailored mental health supports and services, and this is crucial for autistic people.”
The study included cohorts of 379,630 and 334,690 individuals in Ontario, Canada to understand the incidence of self-harm events and suicide death, respectively. Autistic and non-autistic individuals were followed for self-harm events that resulted in emergency care (from 2005 to 2020) and death by suicide (from 1993 to 2018).
Study findings show:
There were significantly more self-harm events leading to emergency healthcare in autistic compared to non-autistic people, across both males (47% increased risk) and females (83% increased risk), after adjusting for neighbourhood income and urban/rural status, intellectual disabilities, and psychiatric diagnoses.
Although both autistic females and males showed higher incidence of suicide death than non-autistic females and males, these increased suicide death risks in both sexes were explained by the presence of psychiatric diagnoses.
“In my twenties, I accessed the emergency room a number of times seeking help for suicidal thoughts and ideations. During that time, I struggled with accessing mental health counselling and support in my city that didn’t have at least a six-month-long waiting list or were affordable, and I waited a over a year to access a psychiatrist,” says Megan Pilatzke, an advocate and autistic woman.
“This is a wake-up call,” says Yona Lunsky, Adjunct Scientist at ICES and Director of the Azrieli Adult Neurodevelopmental Centre at CAMH. “As mental health providers, we need to do more in terms of mental health promotion, and we have to work together with autistic people and their families to make sure that timely mental health supports are accessible, and adapted to meet their needs.”
”Autistic people are continually forced to mask and hide who we are to accommodate a world that generally does not accept our traits,” says Megan. “I want people to understand that autistic people are struggling because our needs are just not being met throughout society.”
“Our healthcare system should take a two-pronged approach to support autistic people,” says Lai: “Enhancing access to mental health services, and autism-informed accommodations for those services. For example, we can support autistic individuals who come into the healthcare settings by offering calming spaces, providing maximal predictability possible, understanding their communication styles and preferences, meeting their sensory needs, and supporting them if they wish to come accompanied by a person they trust.”
The CAMH Azrieli Adult Neurodevelopmental Centre offers resources and tools aimed at individuals, their families, and clinicians to support the mental health of autistic people.
One limitation of the study is that the number of autistic individuals may be underestimated, because individuals who had yet to receive a formal diagnosis, or whose diagnosis was made by private practice psychologists may not have been included. Autistic people could have been miscategorized in the non-autistic group, which would have underestimated suicide-related outcomes in the autistic group. Finally, many self-harm events are not captured by health records, as individuals may not visit the emergency department for health care in these situations.

How to increase acceptance of an RSV vaccine? Explain the FDA’s vaccine approval process
2023-08-08
PHILADELPHIA – A new study finds that people are more likely to recommend that a pregnant family member or friend get vaccinated to protect the infant from RSV illness if they are shown a chart outlining the rigorous process a vaccine undergoes to be approved by the Food and Drug Administration (FDA).
The experiment was conducted by an Annenberg Public Policy Center (APPC) team as part of a May 31-June 6, 2023, nationally representative panel survey on RSV, vaccination, and maternal health. Researchers found that 57% of those in a group exposed to a flowchart of the FDA vaccine approval process (see Appendix 1) were very or somewhat likely to recommend the RSV vaccine to a pregnant ...
Ammonia as a carbon-free hydrogen carrier for fuel cells: a perspective
2023-08-08
Due to the environmental and energy problems caused by fossil fuels, the search for alternative clean and renewable energy solutions has never been more urgent. Among these, hydrogen (H2) is emerging as a leading contender in the energy sector for both stationary and mobile applications. However, the commercial utilization of hydrogen fuel cells is hindered by the challenges of handling and transporting hydrogen due to its low volumetric energy density.
Fortunately, ammonia (NH3) is emerging as a promising hydrogen carrier due to its high hydrogen content (17.6 wt%) and potential economic benefits for energy production. When used as a fuel, it produces only ...
Elevated MRI enhancement ups cancer risk in women with very dense breasts
2023-08-08
OAK BROOK, Ill. – A machine learning model found that background parenchymal enhancement (BPE) on breast MRI is an indicator of breast cancer risk in women with extremely dense breasts, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA).
Women with extremely dense breasts are at a three- to six-times higher risk of developing breast cancer compared to women who have fatty breasts. Since mammography is less sensitive in detecting early-stage breast cancer in women with dense breasts, women between the ages ...

Overlooked CO2 emissions induced by air pollution control devices in China's coal-fired power plants
2023-08-08
To combat this issue, China has implemented various environmental regulations, including the widespread use of air pollution control devices (APCDs) in CFPPs. While APCDs have successfully reduced air pollutants, their electricity consumption has led to indirect carbon dioxide (CO2) emissions. The extent of these CO2 emissions has remained uncertain, prompting researchers to delve deeper into this overlooked environmental concern.
In a new study published in Volume 17 of the journal Environmental Science and Ecotechnology, researchers from Shandong University conducted a study revealing that the proportion of APCD CO2 emissions in total ...
