HealthDay (4/27, Preidt) reports, “Witnessing violence between your parents is traumatic when it happens, but” research indicates that “trauma can raise your risk of depression and other mental health problems.” Included in the study were “more than 17,700 Canadian adults,” 326 of whom “said they witnessed parental domestic violence more than 10 times before age 16, which was defined as chronic.” Among participants “exposed to chronic parental domestic violence during childhood, 22.5% had major depression at some point in their life, 15% had an anxiety disorder and nearly 27% had a substance abuse disorder,” compared to “rates among people with no history of violence between their parents” of “9%, 7% and 19%, respectively.” The findings were published online April 12 in the Journal of Family Violence.

According to NPR (4/26, Hamilton), “brain scan studies have yet to offer much insight into the underpinnings of traits like intelligence, or mental health conditions like anxiety and depression,” investigators concluded after analyzing “nearly 1,000 brain scans,” then checking “their work, using 1,000 different scans.” One “key reason is that these studies need to include scans of thousands of brains, instead of the dozens typically used, a team reported” in findings (PDF) published online March 16 in the journal Nature.

CNN (4/25, Rogers) reports, “The number of suicides among adolescents between the ages of 10 and 19 increased in five states during the pandemic, according to research looking at 14 states.” In addition, “data from Georgia, Indiana, New Jersey, Oklahoma, Virginia and California…showed an increase in the proportion of adolescent deaths by suicide relative to suicides by people of all ages.”

MedPage Today (4/25, Walker) reports, “Adolescent suicides made up a larger share of suicides at the start of the COVID-19 pandemic compared to prepandemic years, according to data from 14 states,” data which “comprised 32% of all U.S. residents and about a third of all adolescents.” The study revealed that “in 2020, individuals ages 10-19 comprised a significantly higher proportion of total suicides versus the prepandemic period of 2015-2019 (6.5% vs 5.9%, respectively), a relative 10% increase,” but even though “there was also an increase in the absolute number of adolescent suicides in 2020, at 903 versus 835.6 on average in the prepandemic years, it was not statistically significant, the authors stated.” The findings were published online in an April 25 research letter in JAMA Pediatrics.
