Robert F. Kennedy Jr. Makes Weird Connection Between Circumcision, Tylenol, and Autism

Robert F. Kennedy Jr. is doubling down on the Trump administration’s declare that taking Tylenol might trigger autism, however with a twist: Alongside along with his previous suggestion that pregnant girls taking acetaminophen are placing their unborn youngster prone to the situation, Kennedy on Thursday claimed that boys who took the painkiller after being circumcised might by some means set off autism.

Through the assembly, Kennedy mentioned that there are “two research that present kids who’re circumcised early have double the speed of autism. It’s extremely probably as a result of they’re given Tylenol.”

Kennedy made the weird connection to circumcision at a White House Cabinet assembly on Thursday, alluding to printed analysis in help of his declare. However these findings are disputed, and at the least one of many research Kennedy appeared to discuss with didn’t take a look at Tylenol use in kids who have been circumcised within the first place.

Circumcision conjecture

Kennedy didn’t particularly cite the “two research,” however a take a look at the literature suggests he could have been referencing—and considerably conflating—the findings of two papers printed in 2013 and 2015, respectively.

The 2013 paper checked out charges of autism, acetaminophen use amongst pregnant moms and younger infants, and circumcision throughout U.S. states in addition to in eight totally different nations. The examine discovered an affiliation between circumcision and autism charges, and the affiliation was strongest after 1995 within the country-level evaluation. The authors argued that since acetaminophen was extra extensively used as a ache reliever after circumcision beginning within the mid-Nineteen Nineties, that might clarify this pattern. Nevertheless, the authors particularly cautioned that their findings “can’t present robust proof of causality.”

The 2015 paper, in the meantime, checked out charges of reported autism and circumcision amongst boys born in Denmark between 1994 and 2003. This examine that discovered boys circumcised earlier than age 5 have been twice as prone to be recognized with autism. The examine authors speculated that the ache of circumcision would possibly trigger adolescence stress that might later result in autism, however not that therapies for the ache, like Tylenol, may be linked to autism. Certainly, the examine authors famous they weren’t in a position to look at how typically kids got Tylenol after a circumcision, that means they couldn’t have examined RFK Jr’s speculation even when they wished to.

The 2015 examine particularly obtained loads of consideration from different researchers upon publication, a lot of whom appeared to be completely unimpressed.

In an editorial printed by the Journal of the Royal Society of Drugs (which printed the unique 2015 paper), scientists not concerned within the examine argued that the investigation was plagued by flaws. Amongst different issues, they identified that many well being situations early in life may cause comparable or better ranges of ache as circumcision, together with urinary tract infections, which are usually extra widespread in uncircumcised boys. Different scientists on the time called the examine’s claims “extraordinarily speculative.” And in 2022, a follow-up systematic assessment failed to find any conclusive proof of a causative hyperlink between circumcision and autism.

It’s additionally price noting that circumcision charges within the U.S. have declined in recent years, whilst autism charges have climbed throughout that very same interval.

Greedy for solutions

Scientists and medical associations have soundly criticized the Trump administration’s makes an attempt to hyperlink Tylenol and autism and to discourage girls from taking the drug as unfounded in science and probably harmful for girls. And whereas some research have urged a potential connection between acetaminophen and autism, probably the most complete and largest research on the subject haven’t discovered any hyperlink, and well being businesses the world over have refused to endorse the speculation. Finally, there isn’t any proof that taking acetaminophen—at any time in life—causes autism.

Kennedy, it appears, maybe is aware of that the proof for his claims is missing. Throughout the identical assembly Thursday, after suggesting that pregnant girls are irresponsible for taking Tylenol, Kennedy mentioned that the proof for a hyperlink between acetaminophen and autism isn’t so crystal clear as he and U.S. President Donald Trump’s suggestion that girls keep away from the drug in any respect prices made it appear. “It isn’t proof. We’re doing the research to make the proof,” Kennedy mentioned.
