Sodas Linked to Aggressive Behavior in Kids

Sodas Linked to Aggressive Behavior in Kids 30477
A new study suggests that the more soda kids drink, the more likely they are to experience behavior problems.

Researchers analyzed data on nearly 3,000 5-year-olds from 20 large U.S. cities. Their mothers completed checklists about the children's behaviors over the previous two months, and also told scientists about the children's habits, such as their diets and how much TV they watched, explains the study's lead author, Shakira Suglia, of Columbia University's Mailman School of Public Health.

Aggressive behavior was measured on a scale between 0 and 100—with higher scores indicating more aggression. Suglia said the average score is 50, and 65 is usually used as a clinical marker of when children should be evaluated for a problem.

Kids who reportedly drank no soda scored 56 on the aggression scale, on average. That compared to 57 among kids who drank one serving per day, 58 among those who drank two servings, 59 among those who drank three servings and 62 for four soda servings or more per day.

After taking into account habits that may have influenced the results—such as how much TV the kids watched, how much candy they ate and their mother's race and education—the researchers still found that drinking two or four or more servings of soda per day was tied to higher aggression scores.

Overall, kids who drank four or more servings of soda per day were twice as likely to destroy other people's belongings, get into fights and physically attack people, compared to children who didn't drink soda.

Soda drinkers also scored higher on scales measuring signs of withdrawal and attention problems, write the researchers in The Journal of Pediatrics.
