    Kids Sweet on Caffeine, Mainly Soda

    Caffeine Intake Among Children Equivalent to Nearly 3 Cans of Soda a Day

    Dec. 16, 2010 -- Three-quarters of children aged 5 to 12 consume caffeine, and it may be keeping them up at night, according to a new study in the Journal of Pediatrics.

    Children aged 5 to 7 took in about 52 milligrams of caffeine per day, and children aged 8 to 12 had about 109 milligrams, the equivalent of nearly three 12-ounce cans of soda per day. That’s much higher than the amount of caffeine linked to effects in adults.

    The more caffeine the children had, the less they slept, the new study showed. Caffeine was not associated with bed-wetting.

    “I would suggest that parents simply be prudent and regulate the amount of caffeine their children consume,” says study author William J. Warzak, PhD, a professor of psychology in the department of pediatrics at the University of Nebraska Medical in Omaha. “They will not be the worse for wear if their caffeine consumption is restricted,” he says in an email. The caffeine in the children’s diet came mainly from soft drinks.

    So what is a moderate amount of caffeine in a 5-year-old or 10-year-old? "I don't think we know the answer to that question,” he says.

    “Most of the research into the health effects of caffeine has been with adults [and] there really is very little pertaining to children,” he says. “The FDA has not established recommended amounts of caffeine consumption in children, although the Canadian government has issued such guidelines and our respondents indicated that quite a few children push those limits.”

    Warzak and colleagues surveyed 201 parents of children aged 5 to 12 from an urban outpatient pediatric clinic. Parents reported information about their child’s daily diet of different beverages and snacks. They also reported information on their child’s sleep and bed-wetting history.

    Soda Linked to Childhood Obesity

    Avram Traum, MD, a pediatric nephrologist at MassGeneral Hospital for Children in Boston, tells WebMD that the amount of caffeine children consumed in this and other studies is “shocking, staggering, and disturbing.”

    The new study looked at how caffeine may affect sleep and bed-wetting, but drinking so much soda may also have an effect on obesity and diseases associated with obesity, including high blood pressure in children, he says.

    “There is no reason that school-aged children need caffeine. Period,” he says. The occasional cup of soda on a special occasion is OK, but children should not drink caffeine on a daily basis.
