RFK Jr. Is Using a New Study on Autism Rates to Push His Anti-Vaccine Agenda

News Feed
Wednesday, April 16, 2025

In a press conference Wednesday morning that surely delighted his allies in the anti-vaccine movement, Health and Human Services Secretary Robert F. Kennedy Jr. responded to a report about apparent rising autism rates with a vow to look at “environmental factors” as a possible cause. While Kennedy didn’t explicitly discuss vaccines, his remarks made it clear, again, that he’ll likely use the power and money of the federal government to prop up the long-debunked claim that vaccines cause autism. He also repeatedly made crude and stigmatizing references to people with profound autism (which he calls “severe” autism,” an outdated term) painting a picture of such people as a burden on society and to their families.  “These are kids who will never pay taxes,” Kennedy declared. “They’ll never hold a job. They’ll never play baseball. They’ll never write a poem. They’ll never go out on a date. Many of them will never use a toilet unassisted. We have to recognize we are doing this to our children.”  “The epidemic,” Kennedy said at another point, “is real.” Autism, he added, “destroys families and more importantly it destroys our greatest resource, our children.” Many children, he claimed, were “fully functional” and “regressed.”  RFK Jr. called today’s press conference to discuss new findings published this week in the CDC’s Morbidity and Mortality Weekly Report, which found an increase in apparent autism rates, from 1 in 36 children to 1 in 31. The report, based on 2022 data, found that the prevalence of autism spectrum disorder was higher in 8-year-old children than in previous years, and higher in Black, Hispanic and Asian Pacific Islander children than in white children. Kennedy made it clear that he believes “environmental factors” are driving the increase in the condition, not genetics. In his previous role as chairman of Children’s Health Defense, Kennedy repeatedly claimed that vaccines cause autism, which they do not, and accused the CDC of lying to “minimize the crisis.” (Among other things, a massive study of 10 million children published in Denmark in 2019 showed no link between the MMR vaccine and autism.) From the podium on Wednesday, Kennedy declared that “overall, autism is increasing in prevalence at an alarming rate” and called it “shocking” and “relentless.” He added, again, and without apparent basis, that “most causes are now severe” and insisted that 25 percent of boys diagnosed with autism “are non-verbal, non toilet-trained and have other stereotypical features” including “stimming and toe-walking,” traits he has brought up frequently in past remarks and cast in a negative light. (Stimming can be a self-soothing behavior, but autistic adults have reported trying to mask it to reduce stigma from others.) “Obviously there are people who don’t want us to look at environmental exposures,” he proclaimed. He said that the newly created Administration for a Healthy America (AHA), which part of HHS, would be responsible for overseeing autism rates. The AHA merged several previously independent offices; HHS has also faced deep cuts and layoffs throughout the agency. Kennedy said future autism studies may look at medication, mold, food addivities, air and water pollution and advanced parental age as other possible factors. There’s long been a scientific debate about how much of the rise in apparent autism rates is due to better diagnosis and detection, with most serious researchers agreeing that better screening plays a major role. Kennedy rejected the idea that autism increases are the result of enhanced diagnostic criteria or better detection. He also trotted out a new phrase, “epidemic denial,” that he clearly plans to use against scientists and media outlets who disagree with his framing of autism rates or their potential causes. At several points, he called people who question or contextualize increased autism rates “deniers” and said they are engaging in “the myth of epidemic denial.”  (Kennedy himself has dabbled in AIDS denialism.)  At the conference, Kennedy also briefly ceded the podium to Rutgers autism researcher Walter Zahorodny, who, among other things, also declared that autism is “real” and “not a quirky personality” trait, and concurred with Kennedy that the CDC report did not simply show better detection but a true increase in autism rates. It “strongly suggests that not only is this a high point in autism prevalence, but in the future rates can only be higher” he added. The Autistic Self-Advocacy Network said in a press release that the new data is “explained by better access to screening and improved understanding of autism.” The group added that more work needs to be done to address the economic and racial disparities that affect which kids receive early, accurate autism diagnoses; for instance, a higher income was related to “a higher diagnosis rate for Black, Hispanic, and Asian and Pacific Islander children.” ”We will continue to advocate to address diagnostic disparities, improve access to diagnosis and support, and protect the programs and services that make this possible,” ASN added.  Responding to Kennedy’s characterizations of autistic people, Alycia Halladay, the chief science officer at the Autism Science Foundation, told Mother Jones that Kennedy “failed to recognize the diverse spectrum of autism.” Of the apparent increase in autism rates, she said, “All of the scientific evidence points to access to services as being a driving force,” adding, “Also, about 20% of autism is caused by a known genetic variant, and there is no evidence that 85% of the increase in prevalence is due to environmental ‘toxins.'” Kennedy has previously vowed to find the cause of rising autism rates by September, which is not how science works. At the conference today, he seemed to slightly walk back that pledge, saying he expected to see “some answers” by September and vowing to “remove the taboo” so that scientists could freely study this issue, which he implied they could not do previously without being “gaslit” or having their licenses taken away.  To add to the concern that any RFK-led studies won’t be serious ones, the Washington Post reported in March that HHS hired David Geier to study vaccine-autism data. Geier is a longtime anti-vaccine figure who, with his father, former physician Mark Geier, purported to study autism and often acted as expert witnesses in cases of alleged vaccine injury. David Geier was disciplined by the Maryland Board of Physicians in 2012 for practicing medicine without a license, while his father’s license was revoked. Neither David Geier nor HHS have responded to repeated requests for comment from Mother Jones. Kennedy promised on Wednesday that HHS’ autism studies would be “thorough and comprehensive.”

Understanding Childhood Obesity: Causes, Treatments and How to Reduce Stigma

By Shagun Bindlish, MD, FACP, FOMA, DABOM, DACLM HealthDay ReporterTUESDAY, Dec. 30, 2025 (HealthDay News) — While childhood obesity has become...

TUESDAY, Dec. 30, 2025 (HealthDay News) — While childhood obesity has become more common in recent years, this is a condition that is about more than just weight.Childhood obesity reflects our modern environment of ultra-processed foods, digital devices and psychological stressors.To address childhood obesity, clinicians and families must work together to create a more nuanced, compassionate and evidence-based approach to prevention and care.What is childhood obesity?Today’s pediatric obesity epidemic involves both a child’s genetics and their environment. While genetics does play a significant role in the development of obesity in children, environments full of ultra-processed foods, screen-focused forms of recreation, poor sleep and mental stress are powerful contributors.Recent research shows that a mother’s health, how a baby is fed, and even exposure to certain chemicals during pregnancy can affect a child’s future metabolism.Combined with aggressive food marketing and environmental and social barriers to regular physical activity across diverse communities, these factors create a “perfect storm” for early metabolic risk.The power of early screeningThe American Academy of Pediatrics (AAP) and Obesity Medicine Association (OMA) recommend that screening for obesity begin as early as age 2. In diagnosing obesity in children, clinicians look for the following:Assessing all of these factors can help clinicians intervene before weight-related issues develop.  The goal is not to put labels on children. It’s to help them build habits early, fostering healthy eating patterns, physical activity and self-esteem during their early years. Tailoring treatment based on age For children who have not entered puberty, the main goal is to normalize growth: maintain a healthy weight so height can catch up. Success depends on parents modeling healthy habits, setting routines and encouraging activity through play. Teenagers need more independence and support for emotional and social issues. Effective care should assess their sleep, stress and emotional eating, and should also check for bullying, depression, disordered eating and the effects of social media.The importance of guidance from caregiversThe most important factor in treating pediatric obesity is family and/or caregivers.Families and caregivers need guidance on nutrition, physical activity, understanding behavior and providing emotional support. Sustainable change is possible when a family works together. Parent-led steps like cooking meals together, being active as a family and limiting certain foods can make a big difference.Behavioral therapy reframes obesity as a chronic, relapsing condition, not a personal failure. It empowers both children and caregivers to replace shame with skills.Both the Obesity Medicine Association and the American Academy of Pediatrics recommend intensive health behavior and lifestyle treatment (IHBLT), defined as at least 26 hours of structured, family-based counseling delivered over 6-12 months.Higher total contact time is associated with greater and more sustained improvements in BMI and cardiometabolic risk.Possibly one of the most important things clinicians can do is speak to children with obesity (and their parents) without putting the focus on weight. Using terms like “health habits” and “growth pattern” and emphasizing body positivity instead of focusing on “weight talk” can help patients feel more comfortable and committed to their treatment.It is also crucial to train staff to use person-first language (“child with obesity,” not “obese child”) to create a welcoming and weight-inclusive environment. This includes having appropriate seating, using a nonjudgmental tone and building trust with patients.For severe obesity, new options approved by the U.S. Food and Drug Administration have emerged, like liraglutide and semaglutide (GLP-1 receptor agonists).These medications must accompany the changes in lifestyle (nutrition, physical activity and behavioral therapy). They should be prescribed by clinicians trained in pediatric obesity medicine.For teenagers with severe obesity and other related health issues, metabolic bariatric surgery offers a durable solution but requires long-term nutritional and emotional support.Building a healthier future for childrenChildren cannot overcome obesity on their own. Effective prevention requires collaboration from their family, health care providers, schools, policymakers and communities.Policies like healthy school meals, walkable neighborhoods, early nutrition education and restrictions on junk food marketing can reduce pediatric obesity better than clinical care alone.Shagun Bindlish, MD, FACP, FOMA, DABOM, DACLM, is an internist and diabetologist with advanced expertise in obesity and lifestyle medicine. She serves as medical and scientific chair for the American Diabetes Association in Northern California and is the founder of the Golden State Obesity Society. An educator at Touro University California and University at Sea CME, she has trained providers worldwide in metabolic health. She is also a recipient of the prestigious Compassionate Physician of the Year Award by the California Medical Association.

Tree Rings May Reveal Hidden Clues About Water History

TUESDAY, Dec. 23, 2025 (HealthDay News) — Trees don’t just clean the air, they also keep a quiet record of the past.New research suggests that tree rings may help scientists uncover missing pieces of environmental history, especially when it comes to water in the midwest. By studying how different tree species respond to wet and dry conditions, researchers say they can better understand how watersheds have changed over time, and how they may change in the future.Watersheds are areas of land that drain water into nearby streams, rivers and lakes. Healthy watersheds help protect drinking water, support wildlife and keep ecosystems balanced, according to the U.S. Environmental Protection Agency. But climate change can put a big strain on these systems, especially when historical data is limited.“One human lifespan is not going to show us the big picture,” study leader Alessandra Bertucci, a graduate student at Ohio State University in Columbus, said in a news release."So using trees to address these gaps of understanding is really important for managing water resources, even in intensively managed watersheds," Bertucci added.Trees typically grow a new ring each year and the size and density of those rings can reflect weather conditions such as droughts, floods and long periods of rain. But not all trees record these events the same way. That’s why the research team found that using multiple tree species gives a clearer picture than relying on just one.The study focused on riparian trees, which grow near rivers and streams in the Midwest. Researchers found that many of these trees are especially good at recording past wet and dry periods, making them useful for understanding regional water patterns.The work was recently presented at a meeting of the American Geophysical Union in New Orleans.To gather their data, researchers collected tree core samples from areas where long-term watershed records are scarce, including Ohio’s Old Woman Creek State Nature Preserve near Lake Erie. They studied three common tree species and compared ring width and density with recorded climate data.Because much of the Midwest is heavily farmed, accurate water data is critical. Bertucci said limited historical records can lead to poor estimates of past floods or droughts, which may affect decisions about water use and conservation.With the updated tree ring data, the team hopes to build models that can help predict how weather patterns and water flow may change in the coming decades.“If we can round out that historical data and understand what to expect, we can better plan for how to manage our water resources in the future,” Bertucci said.Researchers plan to expand their work by sampling more tree species and studying additional watersheds. The findings could help farmers, water managers and communities make smarter decisions about water conservation.“Water is life,” Bertucci said. “We literally cannot live without it, so it’s important to protect and make sure that we are taking care of it, because that is our lifeline.”Research presented at meetings should be considered preliminary, until published in a peer-reviewed journal.SOURCE: Ohio State University, news release, Dec. 19, 2025Copyright © 2025 HealthDay.

How Bay Area cops changed their approach to mental health calls

Photo by Manuel Orbegozo for CalMatters A mental health clinician with a bullet-proof vest is helping change the way a Bay Area city responds to some of its emergency calls. That’s what CalMatters’ Cayla Mihalovich found when she visited the San Mateo Police Department earlier this month to check out a new approach for mental health calls.  The city was one of many that searched for a better way to help people in the throes of a mental health crisis. It participated in a 2021 pilot program from San Mateo County that paired law enforcement officers with mental health clinicians in four cities with the aim of freeing up police officers and avoiding unnecessary confrontations.  Rather than police officers having to decide whether to arrest a person, send them to a hospital for a hold or leave them to their own devices, a paired clinician was deployed to provide additional measures such as safety planning, follow-up calls and community mental health resources.  “I fill in the gaps,” said San Mateo Police Department mental health clinician Briana Fair, who builds relationships with people she calls clients and joins officers on some emergency calls. Known as a “co-responder model,” the pilot appeared to work: Involuntary holds decreased about 17% and it reduced the chances of future mental health calls to 911, according to a new study by Stanford University. By reducing the number of involuntary detentions, researchers also estimated that the cities saved as much as $800,000 a year on health costs. Mariela Ruiz-Angel, director of Alternative Response Initiatives at Georgetown Law’s Center for Innovations in Community Safety: “The idea was never about taking cops out of the equation altogether. The idea was that we don’t have to center them as the main response of 911. We don’t have to make public safety about cops. Public safety is about the appropriate response.” Since the end of the two-year pilot, nearly all of San Mateo County cities have rolled out the co-responder model. Cities that participated in the pilot also found a way to sustain the program, including the police department in the city of San Mateo, which currently employs Fair and another part-time clinician.

Other Stories You Should Know Gun suicides in rural California A collection of Jeffrey Butler photographs on a table at his daughter’s home in Douglas City on Dec. 4, 2025. Photo by Salvador Ochoa for CalMatters In rural California — where medical and mental health care can be hard to come by — firearm suicides particularly among older men are rattling communities and families who have been left behind, reports CalMatters’ Ana B. Ibarra. Rural counties in Northern California have some of the country’s highest rates of gun suicides among older adults. In Trinity County, for example, at least eight men 70 and older died from an apparent firearm suicide between 2020 and 2024. Over the course of 15 years, the gun suicide rate of adults in this age group in seven northern counties, including Trinity, was more than triple the statewide rate.  In addition to owning more guns, residents in these areas have more limited access to medical and mental health services. When these services are farther away, people often remain in pain for longer because of missed or delayed appointments. In California, more than half of people 70 and over who died by gun suicide had a contributing physical health problem, and over a quarter had a diagnosed mental health condition. Jake Ritter, on the death of his 81-year-old grandfather, Jeffrey Butler, who had health and pain issues and died in Trinity County in 2024 from a self-inflicted gunshot: “I’m sad that he didn’t get the help that he needed, and I’m sad that he felt so strongly that this is the road that he chose.” Read more here. New law to prevent sex abuse at schools Students in a classroom in Sacramento on May 11, 2022. Photo by Miguel Gutierrez Jr., CalMatters By July 2026 all California K-12 schools — including private schools — must have protocols in place to help protect schoolchildren from being sexually abused by educators, as directed by a new state law, writes CalMatters’ Carolyn Jones. The law, which goes into effect Jan. 1, requires schools to enact a number of measures to rein in abuse and hold themselves accountable, including training students, teachers and other school staff to recognize signs of sexual grooming and report misconduct.  The law’s most notable provision is the creation of a database that keeps track of teachers credibly accused of abuse. The database will be available to schools so that administrators can use it to vet prospective teachers. The database is intended to curb the practice of schools re-hiring teachers who have resigned from another school after being accused of sexual misconduct. Read more here.

Faulty Genes Don't Always Lead To Vision Loss, Blindness

By Dennis Thompson HealthDay ReporterTUESDAY, Dec. 23, 2025 (HealthDay News) — Genetics aren’t necessarily destiny for those with mutations thought to always cause inherited blindness, a new study says.Fewer than 30% of people with these genetic variants wind up blind, even though the faulty genes had been thought to cause blindness in 100% of those with them, according to findings published Dec. 22 in the American Journal of Human Genetics.The results could shake up a central belief in genetics, that faulty genes always lead to rare inherited disorders. These disorders are called Mendelian diseases, named after the famed genetics researcher Gregor Mendel.“These findings are striking and suggest that the traditional paradigm of Mendelian diseases needs to be updated,” senior researcher Dr. Eric Pierce, director of the Ocular Genomics Institute at Mass Eye and Ear in Boston, said in a news release.The study focused on inherited retinal degenerations (IRDs), a group of genetic diseases that lead to progressive vision loss and eventual blindness. They cause the light-sensing cells along the back wall of the eye to break down and die off.For the study, researchers created a list of 167 variants in 33 genes that have been previously linked to IRDs.The team then screened nearly 318,000 people participating in a National Institutes of Health research program for the presence of those variants, and found 481 with IRD-causing genetics.However, only 28% of those people had suffered any form of retinal disease or vision loss, and just 9% had a formal IRD diagnosis, results showed.The team double-checked their work by using data on about 100,000 participants in another large-scale study, the UK Biobank.Again, only 16% to 28% of people with IRD-linked genetics had suffered definite or possible signs of vision loss or retinal damage, researchers said.The results suggest that something else is happening alongside a person’s genetic risk to make them wind up with IRD, including environmental factors or other faulty genes, researchers said.“We think these findings are important for understanding IRDs and other inherited diseases,” researcher Dr. Elizabeth Rossin, an investigator at Mass Eye and Ear, said in a news release.“We look forward to finding modifiers of disease and using that new knowledge to improve care for patients with IRDs and potentially other inherited eye disorders,” Rossin said.Future studies will examine other Mendelian disorders, and look for other genetic and environmental factors that could cause these diseases.“The large number of individuals that do not develop an IRD despite having a compatible genotype provide an opportunity to design well-powered research studies to discover disease modifiers, which could spur development of novel therapies,” lead researcher Dr. Kirill Zaslavsky said in a news release. Zaslavsky performed this research during an Inherited Retinal Disorders fellowship at Mass Eye and Ear.SOURCE: Mass General Brigham, news release, Dec. 22, 2025What This Means For YouPeople with genetics linked to vision loss and blindness might be able to ward off these problems, if researchers figure out what’s behind the diseases.Copyright © 2025 HealthDay.

As oil and gas companies pivot to plastic, California neighborhoods become sacrifice zones again

As oil and gas companies pivot to plastic, certain California neighborhoods become unhealthy sacrifice zones again.

Guest Commentary written by Veronica Herrera Veronica Herrera is a professor of urban planning at UCLA Daniel Coffee Daniel Coffee is a researcher at UCLA’s Luskin Center for Innovation The fossil fuel industry is pivoting. As demand for gasoline declines, oil and gas companies are betting their future on plastic. What once powered our cars is now being refined, cracked and polymerized into bottles, packaging and single-use products that will outlive us all. This shift isn’t just a climate concern — it’s a public health crisis. Plastics are fossil fuels in another form. And the communities most exposed to their production bear the highest health burdens. A new report from the UCLA Luskin Center for Innovation on what defines a plastic-burdened community traces how this expanding plastic economy maps directly onto California’s oil and gas footprint.  Even as California celebrates its climate leadership, our neighborhoods remain entwined with the legacies of fossil fuel infrastructure. More than 2.5 million Californians live within a kilometer of an active or idle oil or gas well. There are pumpjacks in Inglewood, refineries along the Wilmington corridor and wells beside schools in Kern County.  Refinery infrastructure — much of it feeding plastic precursor production — also is heavily concentrated in Los Angeles County, the most populous region in the state. Unequal exposure The science is unequivocal: living near oil and gas development is linked to a wide array of health harms: respiratory disease, cardiovascular illness, adverse birth outcomes and elevated cancer risk. The higher odds for these conditions persist even when controlling for socioeconomic and environmental factors.  In California and beyond, research shows pollutants from drilling and refining — such as volatile organic compounds, nitrogen oxides, particulate matter and formaldehyde — degrade air quality and increase asthma, heart attack and low-birth-weight rates. The burden of these exposures falls unevenly, our analysis shows.  Neighborhoods closest to wells and refineries have far higher proportions of Latino and Black residents, lower incomes and greater health vulnerabilities. On average, for each refinery within 1.5 miles of a community, the median household income is nearly $11,000 lower, poverty rates are 5.5% higher and emergency-room visits for asthma and heart disease are significantly elevated.  The environmental injustices of the oil age are being repackaged in the plastic economy. Globally, the Organisation for Economic Co-operation and Development projects plastic production will triple by 2060. Petrochemicals already account for roughly 14% of oil use and by mid-century could drive nearly half of global oil demand. In other words, even as we transition away from burning fossil fuels, we are locking ourselves into new forms of dependence — embedded in the packaging we discard daily. Recognizing this link is critical as California prepares to implement the Plastic Pollution Mitigation Fund under Senate Bill 54, a plastics recycling and pollution prevention law signed in 2022. The fund will direct hundreds of millions of dollars from the plastics industry to communities harmed by pollution.  Administered wisely, the fund could be a catalyst for mitigating the adverse health impacts of plastics and could create a transformative shift away from plastic production, use and disposability, building on the plastic reduction efforts required of the industry under SB 54. Plastic pollution is not just about littered beaches or overflowing landfills; it begins long before a product reaches a store shelf.  If California truly intends to lead on climate and environmental justice, it must see plastic for what it is — the fossil fuel industry’s new frontier — and it must ensure that communities long treated as sacrifice zones become the first to benefit from solutions.
