The health of American children has declined sharply over the past 17 years, with troubling disparities in mortality and chronic conditions compared to other wealthy nations. A new study found that U.S. children under 20 are nearly twice as likely to die as their peers in 18 other high-income countries.
Infants in the U.S. had 2.22 times the rate of death from prematurity and 2.39 times the rate of sudden unexpected infant death. Among older children and teens, firearm-related deaths were 15.34 times higher than in peer nations, and motor vehicle fatalities were 2.45 times higher.
From 2011 to 2023, the prevalence of chronic conditions among children aged 3 to 17 rose from 39.9% to 45.7% in pediatric health systems, and from 25.8% to 31.0% in the general population. Obesity, early puberty, sleep problems, activity limitations, and emotional symptoms like depression and loneliness also increased.
The study used data from national surveys, electronic health records, and international mortality statistics. It concluded that U.S. children’s health has deteriorated across nearly every major indicator. “The broad scope of this deterioration highlights the need to identify and address the root causes of this fundamental decline in the nation’s health,” the authors wrote.
These findings raise urgent questions about the social, environmental, and policy factors contributing to worsening outcomes—especially for children in communities already facing systemic disadvantages.
