Ear infections in young children could lead to delayed speech for them, study finds
Chronic ear infections could delay a child’s language development, new research suggests.
University of Florida researchers launched a study about how the common childhood infection could impact speech.
Early ear infections (otitis media) have the potential to impair hearing due to fluid buildup behind the eardrum, according to the study, which was published in the International Journal of Pediatric Otorhinolaryngology in November 2023.

Researchers investigated the auditory processing and language development of 117 kids between 5 and 10 years of age, including those with and without a history of chronic ear infections.
Children who experienced several ear infections before turning 3 had a smaller vocabulary and found it difficult to match similar-sounding words.

These children also had a hard time detecting changes in sound, which could signify a problem in the brain’s auditory processing center.
Study co-author and UF professor Susan Nittrouer, PhD, discussed the findings in a statement to Fox News Digital.
“For most children, language development appears to unfold so effortlessly that it is easy for us to lose sight of what a remarkable feat this is,” she said.

“And ear infections are so common among infants and toddlers that it is easy to view them as completely benign,” she added.
The study uncovered “two somewhat novel findings,” Nittrouer noted.
It’s important for guardians to pay attention to their children’s ear infection history, said the study’s lead researcher (not pictured). (iStock)
The first finding is the association of ear infections with poorer abilities to recognize patterns in the acoustic signals present in speech.
“The central auditory pathways develop after birth,” the researcher said.
“If enough auditory input is not available to the child – which happens with temporary periods of hearing loss due to ear infections – that development of auditory pathways is delayed and these listening abilities do not develop properly.”

The second finding implied that this poor recognition of acoustic patterns impairs the ability of children to identify specific speech sounds, including elements like syllables.
“As they get older, the language they encounter, especially in school, becomes more complex and more dependent on that level of language structure.”
“This is a critical finding,” Nittrouer said. “During early periods of language acquisition, children do not have or need keen sensitivity to phonological structure – individual speech sounds.”
She added, “But as they get older, the language they encounter, especially in school, becomes more complex and more dependent on that level of language structure and the child’s ability to accurately and quickly recognize the individual speech sounds in words.”
One of the study’s “critical findings” was that ear infections can cause poor identification of speech sounds, the lead researcher said. (iStock)
This means that children who are delayed and challenged in their language development will “experience stronger challenges” as they get older, Nittrouer said.
“Contrary to the idea that the child will ‘get over’ or ‘outgrow’ the effects of early [ear infections], these effects may actually intensify,” she said.
“We must take every ear infection seriously.”
Nittrouer encouraged parents and caregivers to monitor children for “language-learning, academic and attentional difficulties,” including reading disabilities, as they age.
“It also means that we must take every ear infection seriously,” she added.
Other early health histories can delay a child’s speech as well, Nittrouer said — which means kids should be monitored for language development “well past the early school years.”
She also said that “the problems arising from such conditions may only present themselves as the language demands of school increase.”

Cedars Sinai Guerin Children’s pediatric otolaryngologist Abhita Reddy, M.D., who was not involved in the study, told Fox News Digital she feels that in her view, the research is “under-powered.”
“The experiment had very few subjects studied and yet drew a broad conclusion from them,” the Los Angeles-based doctor said via email. “When a study has such few subjects in their experiment, often the conclusions can be easily skewed by confounding variables.”

Reddy also pointed out that the chosen population of patients studied was “concerning,” as the study looked at children who reportedly did not have many ear infections as defined by parents.
“[This] can introduce a lot of concern regarding the type of otitis media the child had, as there are two types – acute otitis media and chronic otitis media with effusion – that can have very different effects on patients’ language development,” she said.
The effects of early ear infections could “intensify” as a child grows up, according to the researchers’ findings. (iStock)
The definition of patients who had experienced ear infections was “even more concerning,” Reddy said, since the authors apparently studied patients who had never received ear tubes.
“They did not mention whether the patient had ear tubes during the time of [the] experiment, how many sets they had or what the indications for their ear tubes were,” she said.
The specialist said that in her opinion, parents shouldn’t draw conclusions from this study and she does not believe the research will impact the future of ENT care.
“We know that recurrent acute otitis media in certain patients can be caused by eustachian tube dysfunction (a tube in our bodies that connects the middle ear space to the back of the nose) … [which], if not treated early, can lead to lifelong issues with hearing in the form of conductive hearing loss (ability for sound to transmit to the hearing nerve),” Reddy added.

The first oral GLP-1 medication for weight loss has been approved for use in the U.S.
The Wegovy pill, from drugmaker Novo Nordisk, was cleared by the Food and Drug Administration to reduce excess body weight, maintain long-term weight reduction and lower the risk of major cardiovascular events.
Approval of the once-daily 25mg semaglutide pill was based on the results of two clinical trials — the OASIS trial program and the SELECT trial.
WEIGHT-LOSS DRUGS NOW LINKED TO CANCER PROTECTION IN WOMEN, MAJOR NEW STUDY REVEALS
The Wegovy pill demonstrated a mean weight loss of 16.6% in the OASIS 4 trial among adults who were obese or overweight and had one or more comorbidities (other medical conditions), according to a press release. In the same trial, one in three participants experienced 20% or greater weight loss.

Novo Nordisk reported that the weight loss achieved with the pill is similar to that of injectable Wegovy and has a similar safety profile.

“With today’s approval of the Wegovy pill, patients will have a convenient, once-daily pill that can help them lose as much weight as the original Wegovy injection,” said Mike Doustdar, president and CEO of Novo Nordisk, in the press release.

“As the first oral GLP-1 treatment for people living with overweight or obesity, the Wegovy pill provides patients with a new, convenient treatment option that can help patients start or continue their weight-loss journey.”
POPULAR WEIGHT-LOSS DRUGS COULD TAKE THE EDGE OFF YOUR ALCOHOL BUZZ, STUDY FINDS
The oral GLP-1 is expected to launch in the U.S. in early January 2026. Novo Nordisk has also submitted oral semaglutide for obesity to the European Medicines Agency (EMA) and other regulatory authorities.
“Most side effects will be GI-related and should be similar to the injectable, such as nausea, vomiting and constipation,” an expert said. (iStock)
Dr. Sue Decotiis, a medical weight-loss doctor in New York City, confirmed in an interview with Fox News Digital that studies show oral Wegovy is comparable to the weekly injectable, just without the needles.

Although the pill may result in better compliance and ease of use, Decotiis warned that some patients may not absorb the medication through the gastrointestinal tract as well as with the injectable version due to individual idiosyncrasies in the body.
“Most side effects will be GI-related and should be similar to the injectable, such as nausea, vomiting and constipation,” she said.

“In my practice, I have found tirzepatide (Mounjaro and Zepbound) to yield more weight loss and fat loss than semaglutide by about 20%,” the doctor added. “This has been shown in studies, often [with] fewer side effects.”
More oral GLP-1s may be coming in 2026, according to Decotiis, including an Orforglipron application by Lilly and a new combination Novo Nordisk drug, which is pending approval later next year.

“There will be more new drugs available in the future that will be more effective for patients who are more insulin-resistant and have not responded as well to semaglutide and/or tirzepatide,” the doctor said. “This is great news, as novel drugs affecting more receptors mean better long-term results in more patients.”

As these medications become cheaper and easier to access, Decotiis emphasized that keeping up with healthy lifestyle habits — including proper nutrition with sufficient protein and fiber, as well as increased hydration — is essential to ensuring lasting results.

“If not, patients will regain weight and could lose muscle and not enough body fat,” she said.

A study from Sweden’s Uppsala University discovered a link between microplastics and multiple sclerosis (MS).
The research, published in the journal Environmental International, discovered that exposure to two common environmental contaminants, PFAS and PCBs, could increase the risk of the autoimmune disease.
PFAS, or per- and polyfluoroalkyl substances, known as “forever chemicals,” are used in some common household products, such as non-stick cookware, textiles and cleaning products. They have also been found in drinking water throughout the U.S., according to the U.S. Environmental Protection Agency.

PCBs, or polychlorinated biphenyls, are toxic industrial chemicals once widely used in electrical equipment before being banned decades ago, as stated by the National Institute of Environmental Health Sciences.
The new study findings were based on blood samples of 1,800 Swedish individuals, including about 900 who had recently been diagnosed with MS, according to a university press release.

The first phase of the trial studied 14 different PFAS contaminants and three substances that appear when PCBs are broken down in the body. These were then investigated for a link to the odds of diagnosis.

“We saw that several individual substances, such as PFOS and two hydroxylated PCBs, were linked to increased odds for MS,” lead study author Kim Kultima said in a statement. “People with the highest concentrations of PFOS and PCBs had approximately twice the odds of being diagnosed with MS, compared to those with the lowest concentrations.”
The researchers then examined the combined effects of these substances and found that the mixture was also linked to increased risk.

Fellow researcher Aina Vaivade noted that risk assessments should consider chemical mixtures, not just individual exposures, because people are typically exposed to multiple substances at the same time.
“We saw that several individual substances, such as PFOS and two hydroxylated PCBs, were linked to increased odds for MS,” the lead study author said. (iStock)
The final phase of the study investigated the relationship between inheritance, chemical exposure and the odds of MS diagnosis, revealing that those who carry a certain gene variant actually have a reduced MS risk.
However, individuals who carried the gene and had higher exposure to PFOS — a singular type of chemical in the PFAS family — had an “unexpected” increased risk of MS.

“This indicates that there is a complex interaction between inheritance and environmental exposure linked to the odds of MS,” Kultima said.
“We therefore think it is important to understand how environmental contaminants interact with hereditary factors, as this can provide new knowledge about the genesis of MS and could also be relevant for other diseases.”
Multiple sclerosis is a disease that leads to the breakdown of the protective covering of the nerves, according to Mayo Clinic. (iStock)
Fox News senior medical analyst Dr. Marc Siegel commented on these findings in an interview with Fox News Digital.
“MS is a complex disease that is somewhat autoimmune and somewhat post-inflammatory,” said Siegel, who was not involved in the study. “Epstein-Barr virus infection greatly increases the risk of MS.”

“There is every reason to believe that environmental triggers play a role, including microplastics, and this important study shows a correlation, but not causation — in other words, it doesn’t prove that the microplastics caused MS.”
The study had some limitations, the researchers acknowledged, including that the chemical exposure was measured only once, at the time of blood sampling. This means it may not accurately represent participants’ long-term or past exposure levels relevant to MS development.
“There is every reason to believe that environmental triggers play a role.”
Fox News Digital reached out to several industry groups and manufacturers requesting comment on the potential link between PFAS chemicals and multiple sclerosis.
Several have issued public statements, including the American Chemistry Council, which states on its website that “manufacturers and many users of today’s PFAS are implementing a variety of practices and technologies to help minimize environmental emissions.”
In April 2024, the EPA enacted a new federal rule that sets mandatory limits on certain PFAS chemicals in drinking water, aiming to reduce exposure. The agency also aims to fund testing and treatment efforts.

The immune system’s attack on these nerve sheaths can cause numbness, weakness, trouble walking and moving, vision changes and other symptoms, and can lead to permanent damage.
There is currently no cure for MS, Mayo Clinic reports, but treatment is available to manage symptoms and modify the course of the disease.
