Study finds: 7% of sixth graders severely obese

 According to a new study appearing online in the Journal of Adolescent Health nearly 7 percent of sixth-graders across the U.S. are severely obese.




“Severe obesity in children requires attention because it is associated with high rates of risk for diabetes and cardiovascular disease as children get older,” said Marsha Marcus, Ph.D., lead study author.

Researchers looked at 6,365 middle-school children who had health screenings at 42 middle schools in different locations across the United States.  Half of the children evaluated were minority students or eligible for free or reduced lunch.

Severe obesity was defined differently in children than for adults in this study.  For children, the measurement used is a percentile of body mass index (BMI) for age and sex. For this study, researchers considered children with a BMI in the 99th percentile to be severely obese.   6.9 percent of students fell into this category.

“Ethnic children appear to have higher rates of severe obesity, but rates for all children were high,” said Marcus, who heads the Eating Disorders Program at Western Psychiatric Institute and Clinic, University of Pittsburgh Medical Center.

“The findings of this study are alarming because it shows there are even more children than we realized at medical risk due to excess weight.” Marlene Schwartz, Ph.D., deputy director of the Rudd Center for Food Policy and Obesity at Yale University, said. She has not one of the researchers on this study..

Schwartz has experience with children across the board in clinical and research settings and observed, “In both situations, I have been surprised that some children who are severely obese according to their BMIs do not always look heavy. As a culture, we have become used to seeing heavier children so the visual norm has shifted. Because of this, many children are at risk of not receiving help since their parents do not see them as obese.”

While no simple answer exists, “Parents need to talk to their children’s doctors and seek treatment for children with severe obesity,” Marcus said.
