Data analysis from the Kids' Inpatient Database involving more than 4 million pediatric hospitalizations between 2009 and 2019 found that the number of hospitalizations for kids with mental health problems increased by 25.8%, while hospitalizations involving suicidal or self-harming behavior rose to 64.2% in 2019 from 30.7% in 2009. Researchers suggested in JAMA that hospital admissions could be a factor in the severity and increasing prevalence of mental health conditions in kids.
