, according to a large analysis of Centers for Disease Control and Prevention data.
Sofia Chaudhary, MD, with the Department of Pediatrics and Emergency Medicine at Emory University School of Medicine in Atlanta, Georgia, and colleagues, analyzed data from the National Violent Death Reporting System and found in the cross-sectional study of 40, 618 youths that 24,192 (59.6%) had no such diagnosis previously. Findings were published online in JAMA Network Open.
Gaps by Race, Sex and Age
The odds of having a mental health diagnosis before death by suicide differed by race and sex. Compared with White youths, the odds were lower among youths who were American Indian or Alaska Native (adjusted odds ratio [aOR], 0.45; Asian, Native Hawaiian, or Other Pacific Islander (aOR, 0.58); and Black youths (aOR, 0.62). And more than half of female youths who died by suicide had a mental health diagnosis (4429 youths [52.4%]), compared with 11,994 male youths (37.3%).
The researchers also found wide gaps by age, specifically lower odds of having a mental health diagnosis before suicide in children ages 10-14 compared with those 20-24.
“This finding is particularly notable because suicide rates have risen to become the second leading cause of death in youths aged 10 to 14 years,” the authors wrote. “Suicide prevention strategies for young children in primary care and community settings should focus on fostering resilience, promoting peer and family connectedness, and empowering children with strategies to cope with stress and adversity.”
Youths who died by firearm suicide, the most common mechanism, had the lowest rate of diagnosis. “Similar to a prior study, we found that decedents without a documented mental health diagnosis were far more likely to utilize a firearm than those with a documented mental health diagnosis,” the authors wrote.
In an invited commentary, Lisa M. Horowitz, PhD, MPH, with the Office of the Clinical Director, Intramural Research Program, National Institute of Mental Health, in Bethesda, Maryland, and colleagues wrote that the data show that identifying youth early who have mental disorders or are at-risk for suicide “is more the exception than the rule” in the United States.
The editorialists highlight that the study showed that about one-quarter of youths who have attempted suicide and nearly one-half of youths with depressed mood had no documented mental health diagnosis. Decedents were categorized with depressed mood if they were perceived by themselves or others as depressed at the time of death.
Intervention Recommendations
The study authors point to the high number of youth firearm suicide (the method used by nearly half of those who died — 19,027 (46.8%) and recommended interventions. “Suicide prevention strategies are needed for the estimated 22.6 million US children living in households with firearms, of whom 4.5 million are exposed to firearms stored loaded and unlocked,” they wrote.
A mental health diagnosis was documented for only 6308 of 19,027 youths who died by firearms (33.2%).
They noted that research has shown that more than 75% of guns used in youth suicide are owned by a family member, most commonly parents, and the presence of a firearm in the home is linked with a higher risk of youth suicide.
They wrote that the risk can be mitigated by storing all guns locked and unloaded, with ammunition stored and locked in a separate location.
The editorialists said the study highlights the need for action in several primary areas. “Suicide prevention strategies should not solely rely on a history of mental illness to identify at-risk youths, and universal suicide risk screening in healthcare settings deserves greater consideration,” they wrote.
Equitable access to care is essential to youth suicide risk detection. Interventions such as lethal means safety counseling, safety planning, and a helpline number, such as 988, should be accessible to every family and healthcare clinician.
Community-level interventions are critical, including school-based suicide prevention programs, as well as population-based training for families on the safe storage of lethal means at home.
“Every trusted adult working with children and adolescents can and should be trained to recognize the warning signs of suicide risk and help young people develop the coping strategies needed to manage difficult life experiences so that suicide is never an option,” Dr. Horowitz and colleagues wrote.
