705. THE GLOBAL YOUTH MENTAL HEALTH CRISIS: MEGATRENDS AND SOLUTIONS

Abstract Background There is growing global recognition that mental ill-health is the leading health and social challenge facing young people. Yet, access to care remains poorest for this age group, and the services available are often not fit for purpose, falling short in cultural relevance, developmental appropriateness, and overall quality. This has spawned a worldwide reform movement led by a blend of clinical research leaders and young people which is building new models of care which are versions of enhanced youth friendly primary care. This base camp is evolving and seeks to create a new space in the health system located between childhood and later adulthood, sensitive to the transitional needs and the force of morbidity that threatens the lives and futures of young people from puberty to independent adulthood. Aims & Objectives We aimed to examine the evolving landscape of youth mental health and identify key contributing factors driving the rise in mental ill-health among young people globally. We also sought to explore emerging explanatory frameworks and assess their implications for prevention and intervention strategies. Method We conducted a narrative review to explore contributing factors such as family dynamics, educational pressures, climate change, social media, and socio-economic challenges potentially linked to neoliberal policies. Results We documented mental health trends since the mid-1990s, focusing on mental and substance use disorders among young people and their current needs. Over the very period that youth mental health services focused on the 12–25 year age transition to adulthood began to be assembled, there has been an alarming rise in the incidence and prevalence of mental ill-health in young people. The recent Australian National Study of Mental Health and Wellbeing revealed that the prevalence of operationally defined mental disorders in 16–24-year-olds rose by 50%, from 26% in 2007 to 39% in 2021. The rise in young women was more marked than in young men, with rates reaching 48%. The Australian HILDA survey of 17 000 households/people confirmed a long-term decline in the mental health of this age group. This survey also captured the additional impact of the coronavirus disease 2019 (COVID-19) pandemic and its mitigation strategies. Similar alarming trends had been identified in many other high-income countries well before the COVID-19 pandemic. In 2021, in an advisory to the United States President and Congress, the US Surgeon General, responding to similar trends in the US, described the situation as a “youth mental health crisis.” Discussion & Conclusions These fndings suggested that youth mental health was a rapidly shifting and increasingly urgent issue. While new care platforms were being built, broader social megatrends, including rising inequality, digital saturation, and environmental stressors, continued to drive demand. Our review highlighted the importance of both recognising and addressing these deeper structural forces and reforming existing service systems in parallel. We need to focus on prevention and tackle the megatrends in society that are driving this crisis. In addition to new platforms of care there is an equally urgent need for new workforces and for existing disciplines to deepen and expand their expertise in youth mental health.
