An assessment of the readability of online material related to fluoride.

Community water fluoridation has been deemed one of the greatest public health achievements, yet it remains a controversial topic. As those who are concerned about the benefits and safety of community water fluoridation are likely to turn to the Internet to find information, it is important to know the ease with which a person can read popular materials online. The aim of this study was to assess the readability levels of pro- and anti-fluoride articles on the Internet. Using a highly-recommended readability site, the first 100 articles garnered from websites in a Google were analyzed for a multitude of scores on popular readability tests. Of the 100 articles analyzed, 71 were deemed to be pro-fluoride, and 29 were anti-fluoride. Anti-fluoride materials were more readable across all scores when compared to the pro-fluoride materials. It is critical for consumers to be aware of the credibility of the health information they are reading and to be educated on how to determine if a website or source is reliable, especially when information is conflicting. It is also critical that health associations and other websites devoted to public health promotion develop and provide more accessible health information in terms of readability.

Assessment of Information on Concussion Available to Adolescents on Social Media.

BACKGROUND: Considering how many people obtain information about their health online, the aim of this study was to describe the content of the currently most widely viewed YouTube videos related to concussions and to test the hypothesis that consumer videos would be anecdotal, while other sources would be more informational. METHODS: The term "concussion" was used to search for videos with 100,000 or more views on YouTube that were posted in English or Spanish. Descriptive information about each video was recorded, as was information on whether certain content was conveyed during the video. The main outcome measures are sources of upload and content of videos. RESULTS: Consumer videos accounted for 48% of the videos, television based accounted for 50% of the videos, and internet based accounted for only 2% of the videos. None of the videos viewed fell into the professional category. Television based videos were viewed significantly more than consumer or internet based videos. Consumer and television based videos were equally anecdotal. Many of the videos focused on adolescents and were related to sports injuries. The majority of the videos (70.4%) addressed concussion causes, with 48% stating sports. Few videos discussed symptoms of concussion and prevention. CONCLUSIONS: The potential for widespread misinformation necessitates caution when obtaining information on concussion on a freely accessible and editable medium, such as YouTube.
