The findings in children offer hope against grimmer figures predicted by previous research

Over the past seven years, the prevalence of obesity has hovered at around 36% for adults and at about 17% among children and adolescents,moncler jackets two separate CDC research teams reported online in the Journal of the American Medical Association.

The findings in children offer hope against grimmer figures predicted by previous research, Cynthia Ogden, PhD, of the National Center for Health Statistics, and colleagues wrote.

"Some have suggested that the prevalence of obesity among children will reach 30% by 2030, but the data presented herein suggest that the rapid increases in obesity prevalence seen in the 1980s and 1990s have not continued in this decade and may be leveling off," they wrote.

Still, certain groups of kids -- particularly teenage boys -- may be at greater risk of obesity than others, they warned. Between 1999 and 2010, this group appeared to drive an increase in obesity prevalence, they reported.

For their study, Ogden and colleagues looked at data on 4,111 children and adolescents from the National Health and Nutrition Examination Survey (NHANES) 2009-2010 and compared it with earlier data from the study series.

During the most recent time period, they found cheap moncler jackets 16.9% of children ages 2 to 19 were obese, and the prevalence was higher among males than females (18.6% versus 15%, P=0.01).

It also was higher among Hispanic and black children than whites, they reported (21.1% and 24.3%, respectively, versus 14%).

Even though childhood obesity rose in the 1980s and 1990s, the researchers said, there were no significant changes in prevalence between 2003 and 2010.

There was, however, a significant increase in obesity prevalence between 1999 and 2010 among males (OR 1.05, 95% CI 1.01 to 1.10), which was largely driven by teenage boys. Those ages 12 to 19 were the only age group to have a significant increase in obesity during that time (P=0.04).

The researchers also found that 31.8% of children and teens were overweight or obese in the last year of the survey.

The adult study found that obesity in that group also appears to be flat-lining, with no significant changes in prevalence between 2003 and 2010. That's contrary to the 20 years prior -- from 1980 to 2000 -- when prevalence was moncler on the rise, the researchers reported.

It had been flat prior to that, between 1960 and 1980, they said.

Like the childhood obesity researchers, Katherine Flegal, PhD, of the National Center for Health Statistics, and colleagues also used data from NHANES 2009-2010, but they studied data on 5,926 adults. They also analyzed data from previous NHANES studies from 1999-2008 totaling 22,847 adults.

The overall prevalence of obesity in the most recent period was 35.7% among men and 35.8% among women, they found, and ranged from 36.2% in white men to 38.8% in black men, and from 32.2% in white women to 58.5% in black women.

Prevalence of overweight and obesity combined in 2009-2010 was 68.8%, and the mean body mass index [BMI] for both men and women was 28.7.

Although obesity prevalence didn't rise for all women between 1999 and 2010, there were significant increases among black and Mexican American women, they reported (P=0.04 and P=0.046).

Men, on the other hand, had a significant jump in obesity prevalence over that time (AOR 1.04, 95% CI 1.02 to 1.06, P<0.001). However, rates appeared to cheap moncler plateau around 2003 for both men and women, they found, noting that prior "increases [in obesity] appear to be slowing or leveling off."
