U.S. children's health worsens dramatically since 2007, new study shows

WASHINGTON: A landmark study published in JAMA reveals that the health of U.S. children has deteriorated significantly since 2007, with increases in chronic illness, mental health disorders, and mortality rates. The research, led by Dr. Christopher Forrest, professor of pediatrics at Children’s Hospital of Philadelphia, highlights a growing crisis in pediatric health across the United States.

According to the study, a child in the U.S. in 2023 was 15% to 20% more likely to suffer from a chronic condition than in 2011. Alarming rises were noted in conditions such as depression, anxiety, autism, ADHD, obesity, and sleep apnea, as well as developmental delays and behavioral issues.

Chronic conditions, emotional health on the rise

In-depth analysis of eight national health data sets, including millions of pediatric electronic records, revealed a widespread increase in:

  • Mental health conditions, including anxiety and depression
  • Neurodevelopmental disorders, such as autism and ADHD
  • Physical health issues, including obesity and sleep apnea
  • Social and behavioral symptoms, like loneliness and poor sleep patterns

Dr. Forrest noted:

“Children just seem to be sicker, and the data confirms it. This is a generational shift in pediatric health.”

U.S. youth mortality higher than in other developed nations

One of the study’s most troubling findings is that from 2010 to 2023, American children were 80% more likely to die than their counterparts in other high-income countries. In the 1960s, U.S. child mortality was on par with Europe. Today, the gap is stark.

Among infants, the leading causes of death were sudden unexpected infant death (SUID) and prematurity. In older children and teenagers, the biggest threats were:

  • Firearm-related deaths
  • Motor vehicle crashes
  • Substance use and overdose

Notably, gun violence overtook car accidents in 2020 as the leading cause of death among U.S. youth.

Gaps in health care coverage worsen crisis

In a related JAMA editorial, Dr. Frederick Rivara of the University of Washington highlighted systemic issues contributing to the decline in children's health. Chief among them is the lack of universal health care coverage in the U.S.

“Canada and the U.K. provide universal health care, but many American children remain uninsured or underinsured,” Rivara said.

The situation is expected to worsen due to Medicaid cuts following recent federal budget changes. As of January, 41% of U.S. children were enrolled in Medicaid, according to the Pew Research Center.

Rivara also criticized policy rollbacks that impact public health, including:

  • Budget cuts to the Department of Health and Human Services
  • Elimination of the Safe to Sleep campaign
  • Reduced investment in injury prevention and childhood vaccine advocacy

A call for urgent national response

The findings underscore an urgent call for comprehensive pediatric health reforms, including increased access to care, mental health support, public health investment, and gun safety legislation.

Dr. Forrest concluded:

“We need to rethink how we prioritize children’s health in our policies, systems, and society. The future of our nation depends on the health of our children.”
