Children even more obese than we thought, more exercise crucial for long term health

We’ve known for a while of the obesity epidemic plaguing our country, and especially our children. According to a recent study, extreme obesity in children has reached an alarming level. It’s worse than we thought. Parents, get your kids some exercise! Put them on some skis or a snowboard and let them fly down a mountain. It’s great winter and spring exercise. If you don’t want to spend the dough to ski, which is understandable, go sledding. Hiking up the hill to sled down each time is also a great workout.

If you need more motivation, read up on the study. Start by checking out Kathleen Doheny’s article from WebMD called “Kids Not Only Obese, They’re Extremely Obese”:

“March 18, 2010 — Extreme obesity has reached ”alarming” levels among children, according to a new study that looked at the weights and heights of more than 710,000 children aged 2 to 19.

”The prevalence of extreme obesity was much higher than we thought,” says the study’s lead author, Corinna Koebnick, PhD, a research scientist at Kaiser Permanente in Southern California, a large prepaid health plan.

”Seven percent of boys and 5% of girls — that is scary,” she tells WebMD. That was the overall prevalence of extreme obesity she found. Before the study findings, Koebnick says, she would have expected perhaps 3% to 5%.

And the 7% and 5% figures are overall. For some ethnic groups, the prevalence of extreme obesity was much higher — up to nearly 12%.
Extreme Obesity in Children: Study Details

Koebnick and her colleagues looked at electronic medical charts that had the height and weight of more than 700,000 children who had inpatient and outpatient visits in 2007 and 2008.

The sample studied was gender-balanced, with 357,205 boys and 353,744 girls.

They classified them as overweight, obese, or extremely obese.

Overweight is defined as the 85th or higher percentile on the growth charts, according to guidelines from the CDC. Obese is defined as the 95th percentile or higher.

“Extreme obesity is defined as 120% of the 95th percentile for weight for age and sex,” Koebnick says.

In simpler terms, Koebnick says, ”For a 10-year-old boy or girl, you would expect him or her to weigh about 70 pounds.” If the child weighs 140 pounds, that would be extreme obesity, she says.

”This is the first study using the new CDC definition of extreme obesity,” she says.
Extreme Obesity in Children: Findings

Koebnick’s team found:

    * 37.1% of the children were overweight
    * 19.4% were obese
    * 6.4% were extremely obese

Then they looked at gender and ethnic or racial differences. The prevalence of extreme obesity was highest in Hispanic boys, with as many as 11.2% being extremely obese, and in black girls, with as many as 11.9% of them extremely obese.

The prevalence of extreme obesity peaked at 10 years in boys and at 12 and also 18 in girls, the researchers found.

”This is a serious health issue,” Koebnick says. ”These children are very likely to continue to be obese adults and face all the health consequences that come with obesity at a very early age.” That includes heart disease and diabetes, among other ailments, she says.

Extreme Obesity: Second Opinion

The findings of the new study are no surprise to Lisa Goldman Rosas, PhD, postdoctoral fellow in family and community medicine at the University of California San Francisco School of Medicine, who has researched obesity in Hispanic children. The finding of increased obesity among Hispanic and black children has been consistent, she says. “That’s shown in national data, other studies of Kaiser populations,’’ and other research, she says.
The implications of the study findings are clear, says Sandra Hassink, MD, chair of the American Academy of Pediatrics’ Obesity Work Group and director of the Nemours Pediatric Obesity Initiative at the Nemours/Alfred I. duPont Hospital for Children in Wilmington, Del.

”We need to tackle obesity as soon as we see it,” she says. Better yet, parents can take a family approach to help children stay at a healthy weight.

‘”This is a call to intervene early when you see a child who is at particular risk for this,” she tells WebMD. Once parents notice rapid weight gain or high-risk eating behaviors (such as high amounts of ”junk food”), she advises them to take action. Once a child is severely obese, she says, ”you have psychosocial issues, such as bullying and teasing.”

”Parents who have children in the over 85 to 94th percentile (overweight) need to be focusing even more so on the family environment, [limiting] TV watching, sugary and fast food consumption,” she says.”
