CHICAGO (AP) - A new study says nearly 3 out of 4 U.S. children and young adults consume at least some caffeine.
For most, it comes from soda, tea and coffee. The rate didn't budge much over a decade, although soda use declined and energy drinks became an increasingly common source.
That's according to a government analysis of national health surveys from 1999 through 2010.
The research shows even most preschoolers consume some caffeine-containing products. But their average was the amount found in half a can of soda, and young kids' overall caffeine intake fell during the decade.
The analysis is the first to examine recent national trends in caffeine among children and young adults.
The results were published online Monday in Pediatrics.
