RFK Jr: HHS Press Conference on Autism Rate, 2025-04-16

Video of speech | Source of transcript | The CDC report being referenced | Many of the claims in this speech appear in a blog post from the president of the National Council on Severe Autism.

I’m going to go over some of the key numbers from the ADDM report.

Overall, the autism is increasing in prevalence at an alarming rate.

The study tests eight-year-olds who were born in 2014.

And by the way, these studies are two years later than they should be.

And one of the things that we’re going to do as we move this function to the Administration for a Healthy America, to the new Chronic Disease Division, is we are going to have updated real-time data so that people can look at this, so Americans can understand what is happening with chronic disease in this country in real time.

We don’t have to wait two years to react.

We don’t wait two years to react to a measles epidemic or any kind of infectious disease.

You shouldn’t have to do that for diabetes or autism.

The ASD prevalence rate in eight-year-olds is now one in 31.

Shocking.

There is an extreme risk for boys.

Overall the risk for boys of getting an autism diagnosis in this country is now one in 20.

And it’s high in California, which has the best data collection.

It probably also reflects the national trend, one in 12.5 boys.

This is part of an unrelenting upward trend.

The prevalence two years ago was one in 36.

Since the first ADDM report in 1990, which was 1992 births, autism has increased by a factor of 4.8, that’s 480% I believe.

The first ADDM survey was 22 years ago when prevalence was one in 150 children.

In all the core states, the trend is consistently upward.

And most cases now are severe.

So about 25% of the kids who are diagnosed with autism are nonverbal, non-toilet trained, and have other stereotypical features, headbanging, tactile and light sensitivities, stimming, toe-locking, et cetera.

One of the things that I think we need to move away from today is this ideology that the autism diagnosis, that the autism prevalence increases, the relentless increases, are simply artifacts of better diagnoses, better recognition, or changing diagnostic criteria.

If you look at Table 3 of the ADDM report, it’s clear that the rates are real, that they are increasing in the last 10 years, beginning with the first one.

Year by year there is a steady, relentless increase.

I want to, because this epidemic denial has become a feature in the mainstream media, and it’s based on an industry canard, and obviously there are people who don’t want us to look at environmental exposures.

And so I want to just read you some of the little excerpts from some of the older studies.

The baseline for autism in this country was established with the biggest, largest epidemiological study in history, a study of all 900,000 children in the state of Wisconsin, children under the age of 12.

They found 0.7 percent, 0.7 children had autism in every 10,000.

That’s less than 1 in 10,000, today we’re at 1 in 31.

That study also confirmed the 4 to 1 male to female ratio.

There were at that time just over 60 children in Wisconsin with autism, and today it’s around 20,000.

In 1987, there was another exhaustive study, a peer-reviewed study in North Dakota set out to count every child in the state with a pervasive developmental disorder, including autism.

That study meticulously combed through every record, every diagnosis, and it even conducted the in-person assessments of the entire population of 180,000 children under 18.

The autism rate they found was 3.3 per 10,000.

So that’s in line with the 1 in 10,000 that was found in Wisconsin 17 years earlier.

For context, today the last number, 1 in 36, is 83 times higher.

In 1987, out of every 1 million kids, 330 were diagnosed with autism.

Today, there are 27,777 for every million.

If you accept the epidemic denier’s narrative, you have to believe that researchers in North Dakota missed 98.8% of the children with autism, and thousands of profoundly disabled children were somehow invisible to doctors, teachers, parents, and even their own study.

The same researchers who followed the original cohort for 12 years to double-check their number, they went back in 2000 and found that they had missed exactly one child.

Doctors and therapists in the past were not stupid.

They weren’t missing all these cases.

The epidemic is real.

Between 1959 and 1965, researchers from 14 hospitals associated with major universities undertook a national collaborative perinatal project tracking 30,000 children from birth to age 8.

This was no half-baked survey-based analysis.

The study conducted nine separate screenings covering neurology, psychology, speech, language, hearing, and visual function.

Every developmental quirk, anomaly, and disorder was logged with painstaking detail.

Autism, a condition characterized by profound impairments in social communication and behavior, would have stood out like a neon sign.

There were 14 cases, that’s 4.7 per 10,000.

We know what the historic numbers are, and we know what the numbers are today, and it’s time for everybody to stop attributing this to this ideology of epidemic denial.

In 2009, the California State Legislature charged the MIND Institute at UC Davis with because this myth was already becoming pervasive, the myth of epidemic denial was already becoming pervasive in the mainstream media.

The California Legislature directed the MIND Institute at UC Davis to answer the question, and Irva Hertz-Picciotto, a highly esteemed, revered scientist, neurologist, and epidemiologist, came back with a definitive answer, the epidemic is real.

Only a very, very small portion of it can be charged a better recognition or better diagnostic criteria.

I want to say a couple of other things.

There are many, many other studies that affirm this, and instead of listening to this canard of epidemic denial, all you have to do is start reading a little science, because the answer is very clear, and this is catastrophic for our country.

There’s a recent study by Blaxill et al.

and a team of other researchers that said that the cost of treating autism in this country by 2035, so within 10 years, will be a trillion dollars a year.

This is added to already astronomical healthcare costs, and then there is an individual injury.

These are kids that, this is a preventable disease.

We know it’s an environmental exposure.

It has to be.

Genes do not cause epidemics.

It can provide a vulnerability.

You need an environmental toxin, and Irva Hertz-Picciotto pointed out that because of this mythology, that the amount of money and resources put into studying genetic causes, which is a dead end, has been historically 10 to 20 times the amount spent by NIH and other agencies to study environmental factors, to study exposures, to study external factors, and that’s where we’re going to find the answer.

This is an individual tragedy as well.

Autism destroys families.

More importantly, it destroys our greatest resource, which are our children.

These are children who should not be suffering like this.

These are kids who, many of them, were fully functional and regressed because of some environmental exposure into autism when they were two years old, and these are kids who will never pay taxes, 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, and we have to recognize we are doing this to our children, and we need to put an end to it, and I think I’m going to have Walter Zahorodny, who is the most senior researcher for this project, for ADDM, and who’s been doing this for many years, to come up and say a little.

The study tests eight-year-olds who were born in 2014.

true

The report also studied four-year-olds born in 2018.

The ASD prevalence rate in eight-year-olds is now one in 31.

true

From the first sentence of the results summary of the report: "Among children aged 8 years in 2022, ASD prevalence was 32.2 per 1,000 children (one in 31) across the 16 sites, ranging from 9.7 in Texas (Laredo) to 53.1 in California."

Overall the risk for boys of getting an autism diagnosis in this country is now one in 20

true

The report states it as 49.2 out of 1000.

It probably also reflects the national trend

misleading

This is speculative.

The prevalence two years ago was one in 36

true

This is true according to the ADDM 2020 report, though he's not clear that he's jumped back to the overall rate. The comparison is with 1 in 31 for 2022.

Since the first ADDM report in 1990

false

He seems to mean the year 2000, which is when the first ADDM survey occurred, coving 1992 births.

autism has increased by a factor of 4.8, that’s 480% I believe

false

It is unclear how he calculated 4.8. (1/20) / (1/150) = 7.5.

The first ADDM survey was 22 years ago when prevalence was one in 150 children

true

And most cases now are severe. So about 25%

false

25% is less than 50%.

So about 25% of the kids who are diagnosed with autism are nonverbal, non-toilet trained, and have other stereotypical features, headbanging, tactile and light sensitivities, stimming, toe-locking, et cetera.

true

25% is the approximately correct number for most of these behaviors.

One of the things that I think we need to move away from today is this ideology that the autism diagnosis, that the autism prevalence increases, the relentless increases, are simply artifacts of better diagnoses, better recognition, or changing diagnostic criteria.

false

Ideology is something presented without evidence. The diagnosis-change theory is presented with evidence. See studies here and here. See this article in Scientific American for the context of those studies.

If you look at Table 3 of the ADDM report, it’s clear that the rates are real, that they are increasing in the last 10 years, beginning with the first one.

pants on fire

It is unclear why he refers to Table 3, which presents IQ information. There is no table in the report that supports his claim that the increase is "real" and not the result of changes in diagnosis and recognition. And there is no table in the report that could be compared across historic editions of the report that would support his claim.

I want to, because this epidemic denial has become a feature in the mainstream media, and it’s based on an industry canard, and obviously there are people who don’t want us to look at environmental exposure

false

Canard is something presented without evidence. The diagnosis-change theory is presented with evidence. See studies here and here. See this article in Scientific American for the context of those studies.

900,000 children in the state of Wisconsin, children under the age of 12.

misleading

He is referring to "Epidemiology of Infantile Autism" by Darold A. Treffert, MD, published in 1970. The study lists 899,750 as the estimated population of children aged 3 to 12 in Wisconsin at the time. It pulled data from "30 community mental health and child guidance clinics, four state and county mental hospitals, three colonies and training schools, Children's Diagnostic Center, Children's Treatment Center, and University Hospitals." Like any study, it did not actually inspect all 900,000 children, like his phrasing suggests.

0.7 children had autism in every 10,000

true

69 out of the 899,750 estimated state population of children.

That’s less than 1 in 10,000, today we’re at 1 in 31

true

No review

That study also confirmed the 4 to 1 male to female ratio

false

The study shows 75% male and 25% female, which is a 3:1 ratio.

There were at that time just over 60 children in Wisconsin with autism

false

The number is 69, which is not "just over 60".

today it’s around 20,000

true

38.4 / 10000 * 5.962 milion.

In 1987, there was another exhaustive study, a peer-reviewed study in North Dakota set out to count every child in the state with a pervasive developmental disorder, including autism.

true

He is referring to "A prevalence study of pervasive developmental disorders in North Dakota", published by L Burd, W Fisher, and J Kerbeshian in 1987.

That study meticulously combed through every record, every diagnosis

true

"All physicians (pediatricians. neurologists, psychiatrists. family practice physicians. physiatrists, orthopedic surgeons. and geneticists), mental health centers, developmental disabilities coordinators known to have contact with IA patients. the relevant public and private institutions. and the state's comprehensive developmental evaluation center were re- quested to provide records of all North Dakota children between 2 and 18 years of age who had some or all of the symptoms of PDD."

it even conducted the in-person assessments of the entire population of 180,000 children under 18

pants on fire

This is the estimated population of children in North Dakota at that time, but the researchers did not interview each child.

The autism rate they found was 3.3 per 10,000

false

3.3 per 10,000 is the rate of all pervasive developmental disorders studied. The rate for autism was 1.16 per 10,000.

For context, today the last number, 1 in 36, is 83 times higher. In 1987, out of every 1 million kids, 330 were diagnosed with autism.

false

This is based on his incorrect 3.3 in 10,000 number earlier. The correct 1.6 in 10,000 rate is 174 times higher than 1 in 36, or 116 million.

Today, there are 27,777 for every million

true

No review

, you have to believe that researchers in North Dakota missed 98.8% of the children with autism, and thousands of profoundly disabled children were somehow invisible to doctors, teachers, parents, and even their own study.

misleading

You do not have to believe that. It is up to you to decide if he has convincingly eliminated the other explanations.

The same researchers who followed the original cohort for 12 years to double-check their number, they went back in 2000 and found that they had missed exactly one child.

pants on fire

In the follow-up study researchers checked-in on the cohort identified in their first study. They did not, as RFK Jr. suggests, re-evaluate the population to form a new cohort of cases and compare its size to their original.

Between 1959 and 1965, researchers from 14 hospitals associated with major universities undertook a national collaborative perinatal project tracking 30,000 children from birth to age 8.

true

There were 14 cases, that’s 4.7 per 10,000.

unsubstantiated

This number only appears in a blog post from the president of the National Council on Severe Autism. It cites "a paper by Torrey et al", but it's unclear what paper that is.

the California State Legislature charged the MIND Institute at UC Davis with because this myth was already becoming pervasive, the myth of epidemic denial was already becoming pervasive in the mainstream media.

half false, half true

The 2009 MIND study exists, but there is no reporting of the charge from the legislature or the reason for doing so.

You can read about the MIND Institute's history of parent-driven research direction here.

Irva Hertz-Picciotto, a highly esteemed, revered scientist, neurologist, and epidemiologist, came back with a definitive answer, the epidemic is real

half false, half true

The report concluded:

Younger ages at diagnosis, differential migration, changes in diagnostic criteria and inclusion of milder cases do not fully explain the observed increases. Other artifacts have yet to be quantified, and as a result, the extent to which the continued rise represents a true increase in the occurrence of autism remains unclear.

It is hard to characterize that as a "definitive answer."

Only a very, very small portion of it can be charged a better recognition or better diagnostic criteria.

true

Hertz-Picciotto's study concluded that 68% percent of the 685% increase in the cases in California between 1990 and 2006 could be attributed to the inclusion of milder cases and changing age at diagnoses.

There’s a recent study by Blaxill et al. and a team of other researchers that said that the cost of treating autism in this country by 2035, so within 10 years, will be a trillion dollars a year.

pants on fire

Irva Hertz-Picciotto pointed out that because of this mythology, that the amount of money and resources put into studying genetic causes, which is a dead end, has been historically 10 to 20 times the amount spent by NIH

true

She said that here.

unsubstantiated

He cites no evidence.

these are kids who will never pay taxes, 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, and we have to recognize we are doing this to our children

No rating

Because he says only "many of them" and doesn't give a number, this will not be marked misleading. It is important to note, however, that his description does not match the lives of most people with ASD.
