Time Magazine, U.S. News and World Report, Newsday and CNN were among the major news sources that picked up the story on Thursday.

Dr. Warzak, professor in the Munroe-Meyer Institute, had his study published in the Journal of Pediatrics.

In the study, Dr. Warzak's team found that:

  • 75 percent of children they surveyed consumed caffeine on a daily basis; and
  • The more caffeine the children consumed, the less they slept.

The authors also noticed that the older children drank more caffeinated beverages.

"Children between the ages of 8 and 12 years consumed an average of 109 mg a day," Dr. Warzak said, "the equivalent of almost three, 12-ounce cans of soda."

The researchers also found that caffeine intake was not linked to bedwetting in these children, which is contrary to a popular belief among many parents.
