Conclusions: Pro-anorexia information was identified in 29.3% of anorexia-related videos. Pro-anorexia videos are less common than informative videos; however, in proportional terms, pro-anorexia content is more highly favored and rated by its viewers. Efforts should focus on raising awareness, particularly among teenagers, about the trustworthiness of online information about beauty and healthy lifestyles. Health authorities producing videos to combat anorexia should consider involving celebrities and models to reach a wider audience. More research is needed to study the characteristics of pro-anorexia videos in order to develop algorithms that will automatically detect and filter those videos before they become popular. %M 23406655 %R 10.2196/jmir.2237 %U //www.mybigtv.com/2013/2/e30/ %U https://doi.org/10.2196/jmir.2237 %U http://www.ncbi.nlm.nih.gov/pubmed/23406655
