SAN DIEGO — Researchers believe broader societal changes beginning around 2009 to 2010 severely impacted the mental health of an entire generation of young people, according to research presented during the American Academy of Pediatrics 2026 National Conference & Exhibition Oct. 2-6, 2026, at the San Diego Convention Center.
In a 30-year analysis of data from the national Youth Risk Behavior Surveillance System, researchers found a significant increase in suicidal thoughts and attempts in teens after nearly two decades of previous downturns. The abstract, titled, "A Turning Point in Adolescent Mental Health in the United States: A 30-Year Analysis of U.S. High School Students Using YRBSS Data," also found increased feelings of persistent sadness or hopelessness, rising rates of obesity and insufficient sleep. These factors also resulted in a steady decline in academic performance among teens.
"Our study identified a clear turning point in adolescent mental health around 2009-2010 across various mental health indicators like suicidal thoughts, suicide attempts, sadness, sleep, obesity, and academic performance," said study author Niyati Sharma, who is a junior at Horseheads High School, Horseheads, NY.
"The most surprising finding was not simply that mental health worsened, but that all indicators changed around the same time."
Researchers state that while the study doesn't determine what is causing this shift, it does suggest that broader societal changes could be at play.
"While our study cannot determine what caused these changes, the coordinated shift suggests we may be observing the impact of broader societal changes rather than isolated problems and it deserve much closer investigation to protect the mental health of future generations," Sharma stated.
By pinpointing a starting point of where these changes began, researchers hope to better identify factors contributing to today's mental health crisis and allow researchers, educators, physicians, families, and policymakers to develop more effective and targeted prevention strategies.
