Extremely severe obesity among American children has increased more than threefold over the past 15 years, with new research published on the JAMA Network, highlighting disturbing trends in prevalence and related health complications.
Researchers analyzed national health data from 2008 to 2023, uncovering a surge in the most severe obesity categories for U.S. children aged 2 to 18 years old.
Newsweek has reached out to the authors of the study via email Sunday during non-working hours for further comment.
Why It Matters
The study comes as the nation faces persistent challenges combating childhood obesity, signaling what authors have called a "public health emergency" with wide-ranging medical and economic consequences for future generations.
"The findings underscore the urgent need for public health interventions against pediatric obesity in the U.S.," authors Eliane Munte, Xinlian Zhang, Amit Khurana, and Phillipp Hartmann wrote in the study.
The sharp upswing in extremely severe obesity among children raises the risk of developing serious medical conditions—including type 2 diabetes, steatotic liver disease, also known as fatty liver disease (MASLD), metabolic syndrome, and cardiovascular disease.
According to the U.S. Centers for Disease Control and Prevention (CDC), as of April 2024, approximately 1 in 5 children—14.7 million—are already classified as obese, with the burden disproportionately affecting racial minorities and lower-income families.
Untreated, these complications can persist into adulthood, multiplying risks for chronic disease and shortened life expectancy.
What To Know
The study evaluated data from 25,847 children and teens, drawing from the National Health and Nutrition Examination Survey (NHANES) between 2008 and 2023.
Obesity was categorized using percentiles based on age and sex, and researchers identified a 253 percent relative increase in extremely severe obesity.
Adolescents aged 16 to 18 and non-Hispanic Black children were especially affected.
According to the CDC, the prevalence of obesity in U.S. children and teens aged 2-19 years increased from 19.46 percent in 2008 to 22.52 percent in 2023. Several factors have fueled the rise in pediatric obesity, including decreased physical activity, increased screen time, and greater access to high-calorie, low-nutrient foods.
Researchers noted that these issues intensified during the COVID-19 pandemic, with children experiencing a nearly doubled rate of annual weight gain between 2019 and 2021 compared to prior years.
"The monthly rate of BMI increase nearly doubled...five times faster after the virus appeared," Dr. Alyson Goodman of the CDC said in the British Medical Journal (BMJ) in 2021, highlighting the influence of pandemic-era disruptions.
Economic and social disparities also contribute significantly to who is most affected. The CDC reported higher obesity rates among children in families below 130 percent of the federal poverty level around 25 percent, compared with those in wealthier households at 11.5 percent.
Unequal access to healthy foods, safe recreational spaces, and adequate medical care also play roles, the CDC said in 2024.
The JAMA study found significantly higher odds of children developing MASLD (a fatty liver disease), diabetes or prediabetes, metabolic syndrome, insulin resistance, and early signs of heart disease.
Left unchecked, these conditions can lead to cirrhosis, liver cancer, and major cardiovascular events later in life. In 2024, the CDC estimated the annual medical cost of childhood obesity at $1.3 billion, underscoring the seriousness of the crisis.

What People Are Saying
The authors of the study wrote in the conclusion: "The findings of this study with over 25,800 participants provide robust evidence supporting extremely severe obesity specifically as a public health emergency. The association with metabolic and cardiovascular complications necessitates urgent public health action, such as early prevention, targeted education, and the mobilization of resources."
What Happens Next?
The authors called for "urgent public health interventions" and proposed a multi-layered approach, including preventive education, improved access to nutritious foods, and equitable health care.

COVID-19 cases are rising in these states amid summer wave

The summer surge of COVID-19 is here, with data from the Centers for Disease Control and Prevention showing increases across much of the country. In its latest report, the CDC said the number of cases is now growing or likely growing in at least 26 states and Washington, D.C. COVID-related emergency room visits for young kids are also the highest they've been since March, according to the data. CBS News chief medical correspondent Dr. Jon LaPook told "CBS Mornings" Monday this is typical of what we've come to understand about summer spikes in cases. "We now know that there's a winter spike and then there's a summer spike," he said. "And every year, I just looked last night, the number of deaths, the number of hospitalizations, is gradually going down each season. So that's the good news." But, people shouldn't ignore the increases, he added. "If it strikes you, especially for the vulnerable, and we're talking about very young children under age of 4, the elderly, people who are immunocompromised — there are millions of people who are immunocompromised out there — they can really get sick," LaPook said. New COVID variants Nimbus and Stratus The latest COVID variants, named Nimbus and Stratus, are "no more deadly" than previous variants, LaPook said. Data on previous variants, like NB.1.8.1 from earlier this year, for example, also did not show more severe illness compared to previous variants. Symptoms were broadly similar to those seen in earlier strains, too, including respiratory issues such as cough and sore throat, as well as systemic issues like fever and fatigue. "The vaccines that were made for this season do cover the current variants, so that's good news," LaPook said. "I think the bottom line here is: Don't be blasé. It's the summer, people have all sorts of things. Be careful." Should I get a COVID vaccine booster? While the CDC website still says the COVID-19 vaccine helps protect you from "severe illness, hospitalization and death," there have been some shifts in recommendations. LaPook admits we're in a bit of an odd period right now because the CDC has different vaccine recommendations than many of the major health organizations and societies. The American College of Obstetricians and Gynecologists, for example, says pregnant people should get vaccinated. "Because the baby ... before they can get a shot, they're really relying on the mother's immunity — the mother has the antibodies, goes through the placenta, and then the baby has some protection," LaPook explained. Health and Human Services Secretary Robert F. Kennedy Jr. "said it's now shared decision making," LaPook said. "So that means that go talk to your clinician about it, which is always a good idea, but it's a little bit of a different recommendation than just saying, 'go get it.'" The CDC also now recommends "shared clinical decision-making" for giving healthy children the COVID-19 vaccine. While the agency currently recommends most adults aged 18 and older get a 2024-2025 COVID-19 vaccine, it says it's especially important if you're 65 and older, at high risk for severe COVID-19 or have never received a COVID-19 shot.

As Trump's raids ramp up, a Texas region's residents stay inside — even when they need medical care

WESLACO, Texas — These days, Juanita says a prayer every time she steps off the driveway of her modest rural home. The 41-year-old mother, who crossed into the United States from Mexico more than two decades ago and married an American carpenter, fears federal agents may be on the hunt for her. As she was about to leave for the pharmacy late last month, her husband called with a frantic warning: Immigration enforcement officers were swarming the store's parking lot. Juanita, who is prediabetic, skipped filling medications that treat her nutrient deficiencies. She also couldn't risk being detained because she has to care for her 17-year-old daughter, who has Down syndrome. 'If I am caught, who's going to help my daughter?' Juanita asks in Spanish, through an interpreter. Some people quoted in this story insisted that the Associated Press publish only their first names because of concerns over their immigration status. As the Trump administration intensifies deportation activity around the country, some immigrants — including many who have lived in Texas's southern tip for decades — are unwilling to leave their homes, even for necessary medical care. Tucked behind the freeway strip malls, roadside taquerias and vast citrus groves that span this 160-mile stretch of the Rio Grande Valley are people like Juanita, who need critical medical care in one of the nation's poorest and unhealthiest regions. For generations, Mexican families have harmoniously settled — some legally, some not — in this predominately Latino community where immigration status was once hardly top of mind. White House officials have directed federal agents to leave no location unchecked, including hospitals and churches, in their drive to remove 1 million immigrants by year's end. Those agents are even combing through the federal government's largest medical record databases to search for immigrants who may be in the United States illegally. Deportations and tougher restrictions will come with consequences, says Mark Krikorian, the director of the Center for Immigration Studies, a think tank that favors restrictive immigration policies. 'We shouldn't have let it get out of hand the way we did,' Krikorian says of the previous administration's immigration policies. 'Some businesses are going to have difficulties. Some communities are going to face difficulties.' Federal agents' raids began reaching deeper into everyday life across the Rio Grande Valley in June, just as the area's 1.4 million residents began their summer ritual of enduring the suffocating heat. This working-class stretch of Texas solidly backed Trump in the 2024 election, despite campaign promises to ruthlessly pursue mass deportations. People here, who once moved regularly from the U.S. to Mexico to visit relatives or get cheap dental care, say they didn't realize his deportation campaign would focus on their neighbors. But in recent weeks, restaurant workers have been escorted out mid-shift and farmers have suddenly lost field workers. Schoolchildren talk openly about friends who lost a parent in raids. More than a dozen were arrested last month at local flea markets, according to local news reports and Border Patrol officials. Immigrants are staying shut inside their mobiles homes and shacks that make up the 'colonias,' zoning-free neighborhoods that sometimes don't have access to running water or electricity, says Sandra de la Cruz-Yarrison, who runs the Holy Family Services, Inc. clinic in Weslaco, Texas. 'People are not going to risk it,' de la Cruz-Yarrison says. 'People are being stripped from their families.' Yet people here are among the most medically needy in the country. Nearly half the population is obese. Women are more likely to be diagnosed with cervical cancer and elderly people are more likely to develop dementia. Bladder cancers can be more aggressive. One out of every four people lives with diabetes. As much as a third of the population doesn't have health insurance to cover those ailments. And a quarter of people live in poverty, more than double the national average. Now, many in this region are on a path to develop worse health outcomes as they skip doctor appointments out of fear, says Dr. Stanley Fisch, a pediatrician who helped open Driscoll Children's Hospital in the region last year. 'We've always had, unfortunately, people who have gone with untreated diabetes for a long time and now it's compounded with these other issues at the moment,' Fisch says. 'This is a very dangerous situation for people. The population is suffering accordingly.' Elvia was the unlucky — and unsuspecting — patient who sat down for the finger prick the clinic offers everyone during its monthly educational meeting for community members. As blood oozed out of her finger, the monitor registered a 194 glucose level, indicating she is prediabetic. She balked at the idea of writing down her address for regular care at Holy Family Services' clinic. Nor did she want to enroll in Medicaid, the federal and state funded program that provides health care coverage to the poorest Americans. Although she is a legal resident, some people living in her house do not have legal status. Fewer people have come to Holy Family Services' clinic with coverage in recent months, says billing coordinator Elizabeth Reta. Over decades, the clinic's midwifery staff has helped birth thousands of babies in bathtubs or on cozy beds in birthing houses situated throughout the campus. But now, Reta says, some parents are too scared to sign those children up for health insurance because they do not want to share too much information with the government. 'Even people I personally know that used to have Medicaid for their children that were born here — that are legally here, but the parents are not — they stopped requesting Medicaid,' Reta says. Their worry is well-founded. An Associated Press investigation last week revealed that U.S. Immigration and Customs Enforcement officials have gained access to personal health data — including addresses — of the nation's 79 million Medicaid and Children's Health Insurance Program enrollees. The disclosure will allow ICE officials to receive 'identity and location information of aliens,' documents obtained by the AP say. In Texas, the governor started requiring emergency room staff to ask patients about their legal status, a move that doctors have argued will dissuade immigrants from seeking needed care. State officials have said the data will show how much money is spent on care for immigrants who may not be here legally. Federal law requires emergency rooms to treat any patients who come to the doors. Visits to Holy Family Services' mobile clinic have stopped altogether since Trump took office. The van, which once offered checkups at the doorsteps in the colonias, now sits running on idle. Its constant hum is heard throughout the clinic's campus, to keep medical supplies fresh in the 100-degree temperatures. 'These were hard-hit communities that really needed the services,' de la Cruz-Yarrison says. 'People were just not coming after the administration changed.' Immigrants were less likely to seek medical care during Trump's first term, multiple studies concluded. A 2023 study of well-child visits in Boston, Minneapolis and Little Rock, Arkansas, noted a 5% drop for children who were born to immigrant mothers after Trump was elected in 2016. The study also noted declines in visits when news about Trump's plans to tighten immigration rules broke throughout his first term. 'It's a really high-anxiety environment where they're afraid to talk to the pediatrician, go to school or bring their kids to child care,' says Stephanie Ettinger de Cuba, a Boston University researcher who oversaw the study. A delayed trip to the doctor almost cost 82-year-old Maria Isabel de Perez her son this spring. He refused to seek help for his intense and constant stomach pains for weeks, instead popping Tylenol daily so he could still labor in the farm fields of Arkansas, she says. He put off going to the hospital as rumors swirled that immigration enforcement officials were outside of the hospital. 'He waited and waited because he felt the pain but was too scared to go to the hospital,' she explains in Spanish through an interpreter. 'He couldn't go until the appendix exploded.' Her son is still recovering after surgery and has not been able to return to work, she says. Perez is a permanent resident who has lived in the United States for 40 years. But all of her children were born in Mexico, and, because she is a green card holder, she cannot sponsor them for citizenship. Maria, meanwhile, only leaves her house to volunteer at a local food bank. She's skipped work on nearby farms. And after last month's arrests, she won't sell clothes for money at the flea market anymore. So she stuffs cardboard boxes with loaves of bread, potatoes, peppers and beans that will be handed out to the hungry. Before the raids began, about 130 people would drive up to collect a box of food from Maria. But on this sweltering June day, only 68 people show up for food. She brings home a box weekly to her children, ages 16, 11 and 4, who are spending the summer shut inside. Her 16-year-old daughter has skipped the checkup she needs to refill her depression medication. The teenager, who checks in on friends whose parents have been arrested in immigration raids through a text group chat, insists she is 'doing OK.' Maria left Mexico years ago because dangerous gangs rule her hometown, she explains. She's married now to an American truck driver. 'We're not bad people,' Maria says from her dining room table, where her 4-year-old son happily eats a lime green popsicle. 'We just want to have a better future for our children.' Juanita, the prediabetic mother who hasn't filled her prescriptions out of fear, was not sure when she would brave the pharmacy again. But with a cross hanging around her neck, the devout Catholic says she will say three invocations before she does. Explains her 15-year-old son, Jose: 'We always pray before we leave.' Seitz and Martin write for the Associated Press.

Republicans press Lutnick on AI chip policy

A group of House Republicans pressed Commerce Secretary Howard Lutnick on Thursday to quickly nail down the administration's policy on artificial intelligence (AI) chip exports after rescinding the Biden administration's framework. Eight GOP lawmakers, led by Rep. Mark Alford (R-Mo.), urged the administration to provide a 'stable exporting structure' to replace former President Biden's AI diffusion rule. 'This rule would have helped China win the AI race, and replacing this rule quickly will provide American innovators a stable environment to compete and win,' they wrote in Thursday's letter, first reported by Semafor. The Trump administration rescinded the AI diffusion rule in May. The rule, unveiled in the final days of Biden's presidency, placed caps on chip sales to most countries around the world. Only 18 U.S. allies and partners were exempted from the restrictions. The diffusion rule faced sharp pushback from the semiconductor industry, with major players like Nvidia slamming it as 'misguided.' The Commerce Department pulled the rule shortly before it was set to go into effect, arguing it would 'have stifled American innovation and saddled companies with burdensome new regulatory requirements.' Alford and his GOP colleagues agreed with the administration's assessment, while pushing for a new framework with know-your-customer and security controls. 'We can only win the AI race with Communist China if we are wisely limiting our foreign adversary's opportunities to develop frontier AI and enabling American companies to compete quickly in the global marketplace,' they added. 'Both prongs are important and the balance between them are crucial.' 'America is winning the AI race, but the competition has been hard fought and will continue to be,' the lawmakers continued. 'Steps must be taken quickly since investments happening now will create the world's tech ecosystem for decades to come.' The letter comes after the Trump administration walked back curbs on some Nvidia chip sales to China last week. Nvidia announced last Monday that it was filing applications to sell its H20 chips after receiving assurances from the U.S. government that its licenses would be granted. The chipmaker revealed earlier this year that the administration was implementing new licensing requirements that would limit its ability to sell the chips in China. The reversal prompted pushback from at least one key Republican lawmaker, Rep. John Moolenaar (R-Mich.), chair of the House Select Committee on the Chinese Communist Party. He raised concerns in a letter to Lutnick on Friday, arguing that the move would boost China's AI capabilities.
