...[R]esearchers looked at trends in caffeine intake among people ages 2 to 22 between 1999 to 2010. They found that in 1999, 62 percent of kids and young adults got most of their caffeine from soda. But in 2010, that number dropped significantly to 38 percent.
Energy drinks were not a factor at the beginning of the study, but between 2009 to 2010, they rose to 6 percent of caffeine intake among young people. Coffee also made a jump, from 10 percent of caffeine intake in 1999-2000 to about 24 percent in 2009-2010.
Overall during the time period, researchers found that 73 percent of young people consumed some caffeine on a given day. Even more startling was the fact that 63 percent of kids aged between 2 and 5 consumed caffeine.
The researchers speculated that increased awareness over the link between soda and obesity could be one of the reasons fewer young people are guzzling sodas. But any increase in energy drink consumption among youth is concerning, given that high levels of caffeine can have a greater impact on smaller bodies. The American Academy of Pediatrics says energy drinks "should never be consumed by children or adolescents."
