Middle-school children who consume heavily sweetened energy drinks are 66 percent more likely to be at risk for hyperactivity and inattention symptoms, a new study has found.

"As the total number of sugar-sweetened beverages increased, so too did risk for hyperactivity and inattention symptoms among our middle-school students. Importantly, it appears that energy drinks are driving this association," said Ickovics.
"Our results support the American Academy of Pediatrics recommendation that parents should limit consumption of sweetened beverages and that children should not consume any energy drinks."
While more research is needed to better understand the effects and mechanisms linking sweetened beverages and hyperactivity, previous research has shown a strong correlation between children with attention deficit hyperactivity disorder (ADHD) and poor academic outcomes, greater difficulties with peer relationships, and increased susceptibility to injuries. These associations are understudied among minority children, notes Ickovics, and previous research has suggested under-diagnosis of ADHD in black and Hispanic children.
Some sugar-sweetened beverages and energy drinks that are popular with students contain up to 40 grams of sugar. The students in this study consumed on average two sugared drinks per day, with a range of zero to seven or more drinks. Health experts recommend that children consume a maximum of 21 to 33 grams of sugar daily (depending on age).
In addition to hyperactivity and inattention, heavily sugared beverages also impact childhood obesity, notes Ickovics, and sugar-sweetened beverages are a leading cause of added calories in the diets of obese children. Currently, about one-third of American schoolchildren are considered overweight or obese.
