Study Finds Online Health Misinformation Exposure Concentrated Among Older Adults
A new study from University of Utah researchers has found that while websites containing questionable health information remain relatively rare online, exposure to such content is disproportionately concentrated among older adults, particularly those with right-leaning political views.
The four-week study tracked the web-browsing habits of more than 1,000 U.S. adults, analyzing approximately 9 million URLs visited by participants, including 500,000 YouTube videos. Researchers categorized 1,055 domains as health-related, with just 78 sites (6.8%) deemed to contain low-credibility health information.
“Overall, the levels are pretty low,” said lead author Ben Lyons, an associate professor in the University’s Department of Communication. Only 13% of participants visited at least one dubious health site during the study period, with these visits accounting for just 3% of all health-related browsing activity.
However, the research revealed a concerning pattern: exposure to questionable health content was highly concentrated within a small segment of participants. The top 10% of users accounted for more than three-quarters of all visits to low-credibility health sites, with older adults significantly overrepresented in this group.
“Not all older adults are like this, but the outliers are concentrated among older adults,” Lyons emphasized. This pattern raises particular concerns since older Americans typically face more health challenges and make more medical decisions, potentially increasing their vulnerability to misleading information.
The research team, which included Andy King and Kimberly Kaphingst, collaborated with the University’s School of Medicine and Huntsman Cancer Institute on the study. Their methodology combined survey data collected midway through the four-week period with actual web-browsing and YouTube-viewing data.
Interestingly, the study found that older adults’ engagement with questionable health information differed from their interaction with political misinformation. “The age effect is way bigger for politics,” Lyons noted. “People see politics as way more entertaining than they would health-related content. So there’s less of a motivation to want to share these things.”
The researchers also investigated how users arrived at low-credibility health sites. Contrary to expectations, social media platforms like Facebook and search engines like Google did not appear to be major referral sources. Instead, the data suggested a more insular pattern of consumption.
“What we found, at least in the referral data, is that it’s a more insular type of thing,” Lyons explained. “They’re visiting these because they visit other low-credibility sites, they’re clicking through, and they’re spending more time on these sites. They’re going to them directly.”
Another key finding was that exposure to questionable health content wasn’t random. People who already believed false health claims or held conspiratorial views were more likely to encounter dubious health information, suggesting these users actively seek out such content.
The study’s conclusions point to the need for targeted interventions to improve online health information environments, particularly for older adults. However, the researchers acknowledge that addressing the issue is complex, as it appears tied to broader patterns of internet usage rather than being solely a health misinformation problem.
The findings highlight the importance of developing strategies to help vulnerable populations better evaluate online health information. With seniors increasingly turning to the internet for health guidance, ensuring they have the tools to distinguish credible from questionable sources becomes especially crucial.
The complete study has been published in the journal Nature Aging, offering valuable insights for public health officials, digital literacy advocates, and policymakers concerned with protecting vulnerable populations from potentially harmful health misinformation.

While the overall levels of exposure to dubious health content may seem low, the disproportionate impact on older adults is a serious concern. This study underscores the need for tailored interventions and support systems to protect vulnerable populations.
Absolutely. The outsized influence of a small segment of users is particularly alarming and demands a targeted, multi-faceted approach to address this challenge.
This is an important study highlighting the vulnerability of older adults to online health misinformation. As we age, it’s crucial to be cautious of questionable sources and verify information before accepting it as fact.
Agreed. We need to educate and empower older adults to think critically about the health content they encounter online.
I’m curious to know more about the characteristics of the websites deemed to contain low-credibility health information. What kinds of content or red flags did the researchers use to make those determinations?
That’s a great question. Understanding the specific criteria used to assess the credibility of these health sites would provide valuable insights into the nature of the misinformation problem.
The finding that only a small segment of users account for the majority of exposure to dubious health sites is quite concerning. We need to find ways to reach these high-risk individuals and equip them with the tools to identify misinformation.
Absolutely. Targeted digital literacy campaigns could be an effective approach to help vulnerable populations navigate online health information more safely.
It’s worrying that even a small amount of exposure to dubious health content can have a significant impact, especially among older adults. This highlights the need for robust digital literacy education and fact-checking tools tailored to this demographic.
Agreed. Proactive measures to combat the spread of online health misinformation are essential, particularly for vulnerable populations like the elderly.
The finding that right-leaning political views are associated with higher exposure to health misinformation is an interesting angle. I wonder if this could be tied to broader issues of trust in mainstream media and scientific institutions within certain political circles.
That’s a perceptive observation. The intersection of political ideology, media skepticism, and susceptibility to online misinformation is certainly worth further exploration.
It’s encouraging to see researchers taking a closer look at this issue. Understanding the nature and extent of online health misinformation is the first step towards developing more effective strategies to combat it.
I agree. This study provides valuable insights that can inform future efforts to empower older adults and other high-risk groups to navigate online health information more safely.
