How Research Internships Are Fighting Back Against Alarming Health Trends
A groundbreaking study published in JAMA in July 2025 revealed an alarming truth: the health of American children has been deteriorating across nearly every major indicator over the past 17 years. Children in the United States are now nearly twice as likely to die as their peers in 18 other high-income countries 9 .

Many people assume that children are simply smaller versions of adults, but medical research tells a different story.
Children process medications differently than adults, leading to incorrect dosing when using adult guidelines 4 .
Rapidly developing brain and body systems mean interventions may disrupt normal development 4 .
Conditions present differently in children, causing delayed diagnosis and treatment.
Smaller population for specific conditions creates less commercial incentive for research 4 .
One of the most comprehensive assessments of American children's health ever conducted revealed disturbing trends. Led by researchers at Children's Hospital of Philadelphia and UCLA, the study analyzed 172 health indicators using data from national surveys, mortality statistics, and electronic health records from over 2 million children 9 .
"This study confirms what many pediatricians, educators, and parents have been sensing for years; that our children are facing a growing health crisis. The breadth and consistency of these declines across physical, mental, and developmental health indicators demand urgent national attention."
Understanding and addressing complex child health trends requires diverse methodological approaches. At leading pediatric research centers, investigators employ various specialized methodologies to untangle the complex web of factors influencing children's health .
| Methodology | Application in Child Health | Unique Pediatric Considerations |
|---|---|---|
| Clinical Epidemiology | Studies patterns, causes, and effects of health in patient populations | Must account for developmental stages |
| Clinical Trials | Tests diagnostic or therapeutic approaches | Requires special ethical protections for children 4 |
| Comparative Effectiveness | Determines what works best in medicine | Needs child-specific outcome measures |
| Implementation Science | Studies how to adopt evidence-based practices into routine care | Must adapt to various pediatric settings |
| Biostatistics | Develops statistical methods for biomedical research | Requires techniques for small sample sizes common in rare pediatric conditions |
The Child Health and Nutrition Research Initiative method has emerged as a dominant approach for setting health research priorities in child health 5 . This systematic method helps experts evaluate and rank research ideas based on their potential to reduce disease burden in populations in a feasible and cost-effective way.
Despite concerning trends, the field of child health research continues to produce groundbreaking innovations that offer promise for improving children's health outcomes.
Combining protection against six deadly diseases in a single injection makes it easier for children to receive complete immunization while reducing burdens on caregivers and healthcare systems 8 .
About the size of a small bandage, these patches may soon allow volunteers rather than highly trained health workers to administer vaccines safely and effectively 8 .
The National Research Council and Institute of Medicine have proposed defining children's health as:
"The extent to which individual children or groups of children are able or enabled to develop and realize their potential, satisfy their needs, and develop the capacities that allow them to interact successfully with their biological, physical, and social environments" 7 .
This expanded view recognizes that children's environments fundamentally shape their health trajectory 2 .
The recent alarming findings about declining child health underscore the critical importance of training and inspiring new generations of researchers dedicated to addressing these complex challenges.
Connecting emerging scientists with experienced researchers
Developing new approaches to complex health challenges
Working across disciplines to improve child health outcomes
The complex health challenges facing children – from mental health crises to chronic disease increases – will not yield to simple solutions. They demand researchers who understand the unique aspects of pediatric biology, who can employ diverse methodological approaches, and who recognize the broad environmental and social factors that shape children's health outcomes.
As we look to the future, the need for innovative, dedicated child health researchers has never been greater. Though the path forward is challenging, the scientific community's growing understanding of both the biological and contextual factors influencing child health – combined with the passion and fresh perspectives that new researchers bring – offers genuine hope for reversing current trends and building a healthier future for all children.
