Researchers from Nationwide Children's Hospital in Columbus, Ohio, and the federal Health Resources and Services Administration measured mental health-related ER visits among children 5 to 17 years old between 2007 and 2016. They found that while the number of pediatric visits for any cause remained relatively level over the decade, visit rates per 1,000 population surged 329% for deliberate self-harm and 117% and 111% for anxiety and impulse-control disorders, respectively.
