Consulting Dr. YouTube: How digital misinformation may keep you from a good night’s sleep

Brigham and Women’s Hospital study highlights the prevalence of misinformation among popular YouTube videos addressing sleep health

2023-02-27

(Press-News.org) More than 60% of adults in the United States report accessing the Internet for health-related questions. Social media and content platforms like YouTube offer a vast wealth of content on sleep health, from tips on how to get a good night's sleep to managing sleep disorders and insomnia. A new study from researchers at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, identifies an alarming amount of medical misinformation in videos about sleep disorders on YouTube. Researchers identified that “popular” videos created by bloggers garnered significantly more views than expert-led videos and contained both misinformation and consumer bias. Results are published in the Journal of Clinical Sleep Medicine.

"What's tricky is that so much of health information is very nuanced, and a lot of popular YouTube videos have clickbait and appeal to shorter attention spans," said lead study author Rebecca Robbins, PhD, Investigator in the Brigham’s Division of Sleep and Circadian Disorders and an Instructor in Medicine at Harvard Medical School. "People today often want very bite-sized pieces of information. However, science is fundamentally more nuanced than a one-liner or the 280 characters in a Twitter post."

To conduct the study, the team searched YouTube using key terms such as “insomnia” and “sleep tips,” to identify and label popular YouTube videos on sleep medicine. They then sorted videos by views and identified those with the highest number of views as “popular.” They compared these popular videos to videos from credible sources identified by a feature on YouTube that placed content from healthcare systems at the top of search results for health-related terms.

The videos were then assessed for the quality of information they contained by sleep experts trained to identify misinformation using validated health communications assessment tools, including the Patient Education Materials Assessment Tool (PEMAT) and the DISCERN brief questionnaire. The study found that the videos that received the highest number of views were most often produced by bloggers (42.9%), followed by medical professionals and health coaches (33.3% and 23.8%, respectively). While popular videos averaged 8.2 million views, those led by experts received only 0.3 million views.

None of the identified expert-led videos contained commercial bias, or the promotion of a product or service, yet 66.7% of popular videos featured such biases. Even though popular videos presented significantly more misinformation, investigators did not identify any differences in the understandability of content presented between the expert-led and the popular videos.

Researchers cannot pinpoint exactly why consumers tend to seek information on sleep health from videos created by bloggers over those from sleep experts but attribute these trends to content creators' ability to produce media that is engaging, aesthetically appealing, and relatable to viewers.

“Medical misinformation, including what’s found in some videos about sleep disorders, can lead to patients avoiding care or receiving the wrong care and can be detrimental to patient outcomes,” said senior study author Stuart Quan, MD, Clinical Chief and Medical Director of the Brigham’s Sleep Disorders Service in the Division of Sleep and Circadian Disorders. "Sleep Medicine is not immune to this issue."

Investigators acknowledged limitations in that the types of videos which experts deemed “popular” are ever-changing. Additionally, while the study focused specifically on YouTube, the team hopes to expand the research to include other social media platforms such as Instagram and TikTok. The researchers also expressed hope that, in the future, platforms such as YouTube will continue to find creative ways to partner with health professionals to combat misinformation.

New method for the detection of RNA viruses such as SARS-CoV-2

2023-02-27

Experts from the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Aragon Nanoscience and Materials Institute of Aragon (INMA) —a joint institute of the CSIC and the University of Zaragoza— have developed a new method to detect RNA viruses based on the triplex-forming probe technology. This innovative methodology opens up new options for detecting viruses such as SARS-CoV-2, the influenza A virus (H1N1) or the respiratory syncytial virus (RSV), a pathogen that ...

Chaos on the nanometer scale

2023-02-27

Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos – other effects predominate. Now, for the first time, scientists at TU Wien have been able to detect clear indications of chaos on the nanometer scale – in chemical reactions on tiny rhodium crystals. The results have been published in the journal ...

(Boston)—Many pregnancy complications are associated with future heart disease. Such complications include gestational diabetes, preterm birth, fetal growth restriction and hypertensive disorders of pregnancy (gestational hypertension, preeclampsia and related disorders), and together they are referred to as adverse pregnancy outcomes (APOs). Although APOs are recognized as a useful way to identify individuals with increased risk for future heart disease, it is not known how often APOs occur before traditional heart ...

New Orleans, LA – A study led by Vinod Dasa, MD, Professor of Orthopaedics at LSU Health New Orleans School of Medicine, reports that a novel surgical pain management strategy following total knee arthroplasty (TKA), or total knee replacement, provided pain relief without opioids. The researchers also found that changing prescriptions for opioids at discharge from automatic to upon request dramatically decreased opioid use. Their results are published in the Journal of Experimental Orthopaedics, available here. “About 70% of opioid-naïve ...

The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past

2023-02-27

Green leaves and photosynthesis were once considered key features of plants. However, some plants have since abandoned this process, obtaining their nutrients from other organisms. One such plant is the genus of Thismia, commonly known as fairy lanterns, which is characterised by its unusual appearance, elusiveness, and lack of photosynthesis. Fairy lanterns are rare and only grow in specific places. They live underground with their colourful flowers rising above the soil, which can sometimes make them look like mushrooms. Around 90 species of Thismia have been found, but many are ...

Study identifies four distinct pain trajectories in nursing home residents

2023-02-27

INDIANAPOLIS – Despite awareness that pain is common in nursing home residents, there has been minimal attention focused on how this pain changes over time. A new study from Regenstrief Institute and Indiana University School of Nursing researchers presents compelling evidence of the existence of four distinct pain trajectories in this population. This new understanding of pain over time can help nursing home staff and clinicians better understand, recognize and respond to risk factors associated with persistent pain in individuals living in nursing homes. Ultimately, consideration of pain trajectories may alter courses of care and illness, ...
