Researchers at the University of Utah tracked the web browsing of more than 1,000 US adults for four weeks. They combined survey answers with actual browsing and YouTube viewing data to see what health information people met online.
During the study participants reached about nine million web addresses and many videos. The team labeled 1,055 domains as health sites and found 78 of those domains were low-credibility. Few people visited these sites, and those visits made up only a small part of all health browsing.
Visits were especially common among older adults, and the researchers say helping seniors check information could be important. They also found that people who already believed false claims were more likely to encounter dubious content.
