Kids Gulping Down More Sugary Beverages

In another study published in the same issue of the journal, researchers from the University of Minnesota found that even parents who recognized their child was overweight did not take "healthy" actions at home -- such as providing plentiful supplies of fruits and vegetables -- to help their child.

Dr. Dianne Neumark-Sztainer and her team evaluated the behaviors of parents whose teens participated in Project EAT, analyzing data from 314 parent-teen pairs.

"Basically, we compared parents of overweight children who recognized their children were overweight with parents of overweight children who did not recognize their children were overweight to see if knowing your child is overweight is associated with better behavior," Neumark-Sztainer said.

They asked parents about several behaviors, such as providing more fruits and vegetables and fewer soft drinks, salty snacks and candy; having more meals as a family; watching less television during dinner and encouraging children to make healthy food choices and be active. They also asked the parents if they encouraged their children to diet.

The only difference? Those who recognized their child was overweight were more apt to encourage their child to diet. "And that turns out to be bad," Neumark-Sztainer said. "Those kids actually weighed more five years later."

Both studies are concerning, said Connie Diekman, director of university nutrition at Washington University in St. Louis and immediate past president of the American Dietetic Association.

"The fact that parents who know their children are overweight don't provide positive guidance, healthier food options and encouragement to get physical activity in is a big concern in that parents' behaviors eventually become their children's behaviors," she said. "It would seem that parents need more education on how to encourage healthy living."

What should parents do? Wang doesn't advocate eliminating sugary drinks but being educated about their role. "Be aware there are a lot of calories [in the beverages], and kids need to exercise a lot to burn it off," she said.

Sweetened beverages and naturally sweetened fruit drinks should be limited to four to six ounces a day for kids aged 1 to 6 and eight to 12 ounces for those aged 7 to 18, Wang said. In her study, the daily average consumption from 1999 to 2004 was 25 ounces.

"Make health eating and activity habits a priority for the family," Diekman stressed.
