American children are the sickest children in the developed world.

Nov 8, 2026

Previously: American children are the sickest children in the developed world. [One-sided]: A 2025 JAMA study from Children's Hospital of Philadelphia found US children aged 1 to 19 died at 1.8 times the rate of children in 18 peer wealthy countries, and found chronic conditions among US kids rising since 2011. But much of that death gap comes from guns and car crashes, not illness, and the study did not compare chronic disease rates across countries. So calling US kids the 'sickest' goes beyond what has actually been measured. A peer-reviewed cross-country comparison showing US children have the highest chronic illness rates among wealthy nations would turn this into a supported claim.

Now: American children are the sickest children in the developed world. [Unverified]: US child health is deteriorating, but the claim that American children rank worst for every chronic illness is not established. The 2025 JAMA study documents worsening US outcomes and compares mortality with 18 wealthy countries; it does not rank every childhood disease worldwide or across human history. Mortality includes injuries and cannot substitute for a universal disease ranking.
