The world is facing what researchers call “an emerging crisis”—a troubling rise in death rates among teenagers and young adults. A comprehensive study published in The Lancet as part of the Global Burden of Disease (GBD) project has revealed that despite overall improvements in global life expectancy, younger populations are increasingly at risk.
The report, unveiled at the World Health Summit in Berlin, analyzed data from over 16,500 scientists across 204 countries. While average life expectancy now stands at 76.3 years for women and 71.5 for men, the study warns of “stubbornly high or rising death rates” among youth—a reversal of decades of progress.

From Mental Health Crises to Infectious Disease
The causes of this worrying trend vary by region. In North America and parts of Latin America, deaths among teens and young adults are largely driven by suicide, drug, and alcohol use.
Dr. Christopher Murray, Director of the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, said the surge in mental health issues—particularly anxiety and depression among young women—has become deeply concerning.
“Rising deaths in younger adults are very tied up with the rise of anxiety and depression,” Murray noted. “There’s still debate around the causes—whether it’s social media, technology, or broader societal changes.”
In contrast, sub-Saharan Africa faces a different crisis. The study found higher-than-expected deaths in children aged 5–14, mainly from infectious diseases and accidental injuries.
For girls and women aged 15–29, mortality rates were 61% higher than earlier estimates—mostly due to pregnancy complications, road accidents, and meningitis.

Half of Global Ill Health Is Preventable
Beyond youth mortality, the study found that chronic diseases—including heart disease, diabetes, and mental health disorders—now account for two-thirds of global ill health.
Researchers estimate that 50% of the world’s disease burden is preventable, driven by factors such as high blood pressure, air pollution, smoking, and obesity.
Dr. Murray emphasized that these findings should be a wake-up call for governments and healthcare leaders, urging swift, strategic public health responses.

Calls for Youth-Centered Health Investment
Dr. Githinji Gitahi, CEO of Amref Health Africa, said Africa’s youthful population—60% of whom are under 25—represents “an incredible potential” that must be safeguarded through health investment.
“Siloed healthcare systems are failing young people,” Gitahi warned. “We’re seeing young lives lost not only to malaria, HIV, and tuberculosis but increasingly to non-communicable diseases and poor nutrition.”
He called for integrated, youth-focused healthcare systems that address both infectious and lifestyle-related diseases.

The Global Health Funding Gap
Professor Emmanuela Gakidou, senior author of the study, cautioned that cuts to international aid threaten decades of progress in low-income nations.
“These countries rely heavily on global health funding for life-saving care, medicine, and vaccines,” she said. “Without it, the gap in health outcomes will widen.”
Conclusion
The GBD study paints a stark picture of growing inequality in youth health outcomes—a crisis driven by preventable risks, mental health struggles, and weak global health systems. As experts warn, governments must act now to protect young lives and strengthen global health resilience.
