Youth Mental Health Spotlighted at U.S. Launch of the Second Lancet Commission on Adolescent Health and Wellbeing

In October 2025, global health leaders, policymakers, youth advocates, and researchers convened in the nation’s capital for a two-day A Call to Action for Youth Mental Health. The event served as the U.S. launch of the report of the Second Lancet Commission on Adolescent Health and Wellbeing, an international effort to address the urgent and escalating challenges facing adolescents worldwide. Hosted by the Johns Hopkins Center for Global Mental Health, the convening followed the World Health Assembly launch in May 2025. 

The next steps will be to continue collaborating with partners across the U.S. and the world to support the actions responsive to youth needs, including, 

  • Integrate youth lived experience expertise into mental health research, policy, and practice
  • Apply data-driven accountability for equitable access to quality care
  • Shape urban environments to promote youth mental health
  • Understand gendered drivers and tailored responses to support youth mental health
  • Catalyze intersectoral engagement for youth mental health: health, education, and social support systems
