About one-third of adults and 17% of children and teens were obese in 2011-2012, according to a national survey study, a rate that hadn’t changed in the previous decade.
CDC researchers examined trends for childhood and adult obesity among 9,120 people in the 2011-2012 nationally representative National Health and Nutrition Examination Survey.
Results appeared in the Feb. 26 issue of JAMA.
For children, the marker of obesity was high weight for recumbent length from birth to age 2. The overall rate was 8.1% in 2011-2012, with a difference between boys (5%) and girls (11.4%). Among children ages 2 to 19, 31.8% were either overweight or obese, and 16.9% were obese. Obesity among children 2 to 5 years of age decreased from 14% in 2003-2004 to just over 8% in 2011-2012 (P=0.03).
Among adults, 68.5% were either overweight or obese, 34.9% had a body-mass index (BMI) of 30 or greater, and 6.4% had a BMI of 40 or greater. Obesity in women age 60 years and older increased from 31.5% to more than 38% (P=0.006).
