“Childhood Obesity Rates Stabilizing: Researchers at the Centers For Disease Control And Prevention (CDC) report that rates of childhood obesity have remained statistically the same for the past 10 years, with the exception of the prevalence of obesity among boys (2 to 19 years old) increased from
14 percent in 1999 to 2000 to
18.6 percent in 2009-2010,”
according to Ryan Masters, PhD who conducted research as a Robert Wood Johnson Foundation Health & Society Scholar at Columbia University’s Mailman School of Public Health.

“However, rates of obesity among children ages 2 to 19 are still far too high—more than triple what they were in 1980.”

“According to the most recent National Health And Nutrition Examination Survey (NHANES),
16.9 percent of children ages 2 to 19 are obese, and
31.7 percent are overweight or obese,”
according to Ryan Masters, PhD who conducted research as a Robert Wood Johnson Foundation Health & Society Scholar at Columbia University’s Mailman School of Public Health.

“This translates to more than 12 million children and adolescents who are obese and more than 23 million who are either obese or overweight.”
