CDC: Child and Teen Obesity at Record High

Childhood obesity in the United States has reached a troubling new milestone. According to a recent report from the Centers for Disease Control and Prevention (CDC), more than one in five children and teenagers now live with obesity. This is the highest rate ever recorded.
For public health experts, the numbers are not just statistics. They represent a generation at heightened risk for chronic disease and long-term health complications.
The CDC’s latest data, drawn from the long-running National Health and Nutrition Examination Survey (NHANES), show that between 2021 and 2023, 21.1% of U.S. youth ages 2 to 19 had obesity. By comparison, in the early 1970s (1971–1974), that figure stood at just 5.2%.
“This is exceptionally concerning,” said Dr. David Ludwig, professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health and co-director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital.
Decades ago, Ludwig noted, obesity in children was rare: about one in 20. “And now we’re looking at one in five children with obesity,” he said. Even more alarming: 7% of children now live with severe obesity, up from just 1% roughly 50 years ago.
For a brief period in the early 2010s, there appeared to be progress — at least among the youngest children. Between 2009 and 2010, obesity rates among 2- to 5-year-olds were 12.1%. By 2013–2014, that number had dropped to 9.4%. Experts cautiously celebrated what seemed like a turning point.
But the optimism was short-lived. Today, obesity rates in that same age group have climbed to 14.9%.
Dr. Ludwig said:
We saw that dip and we all got excited thinking that we were beginning to turn the tide… In retrospect, that was more of a statistical aberration, more of a mirage than a true glimmer of hope because the trend overall has continued upward.
The reversal underscores how complex and entrenched the childhood obesity epidemic has become.
Interestingly, while childhood obesity continues to climb, adult obesity rates may be showing early signs of stabilization. In the most recent CDC survey (2021–2023), 40.3% of adults age 20 and older were classified as obese. That’s significantly higher than the 22.9% recorded between 1988 and 1994, but slightly lower than the peak of 42.4% seen in 2017–2018.
Dr. Justin Ryder, associate professor of surgery and pediatrics at Northwestern University Feinberg School of Medicine, warned that past dips have sometimes been statistical blips rather than lasting trends. He said:
Could it just be the people who were sampled, or is it real? We won’t know until we have more data over time.
One factor that may be contributing to the stabilization in adults is the growing use of GLP-1 receptor agonists, a class of medications originally developed to treat Type 2 diabetes. These drugs mimic the GLP-1 hormone, helping regulate blood sugar and signal fullness to the brain. In recent years, several have become household names, including Ozempic, Wegovy, Mounjaro, Zepbound, and more. While these medications are increasingly common among adults, pediatric use remains more limited and carefully regulated.
So, what will it take to reverse the trend in children? Experts say the answer depends on age.
Ages 2–5: Focus on early lifestyle interventions — healthy eating habits, reduced ultra-processed foods, and increased physical activity.
Ages 6–11: Lifestyle changes remain central, though some medications may be appropriate in certain cases.
Ages 12–19: Adolescents with obesity — nearly 23% in the latest survey — may meet criteria for intensive treatment, including medications or, in some cases, bariatric surgery.
Dr. Ryder emphasized the need to apply existing clinical practice guidelines more consistently for adolescents. He said:
I think the only way that we’re going to see a downward trend in that number is if we take that adolescent group […] and actually start to apply the clinical practice guidelines and treat those kids seriously.
The contrast between potentially stabilizing adult obesity rates and record-high childhood obesity underscores a sobering reality: Prevention efforts may be arriving too late for many children. When obesity begins in childhood, it often persists into adulthood, compounding health risks over decades.
The CDC’s latest data represent more than a statistical benchmark. They serve as a warning that without sustained, multi-layered efforts, spanning families, schools, healthcare systems, and public policy, the upward trajectory is unlikely to reverse on its own.
For now, the numbers are clear: One in five American children is living with obesity. Whether this becomes a permanent feature of modern health — or a turning point that sparks renewed action — remains to be seen.
