Studies have been assessed the importance of YouTube as a source of information for some health conditions, diseases or procedures. However, this platform provides an ever-growing, unregulated source, and some of their information may cause health risks to patients.


The aim of this study was to evaluate the use of Brazilian YouTube videos as a source of useful in-formation about diabetes foot care.


The website was searched on November 30, 2016, for the term “diabetes foot care” in Brazilian Portuguese to assess their usefulness as an information source. The videos were categorized as very useful, moderately useful, somewhat useful, and not useful. The video sources were categorized into 4 groups: organizational, professional, personal and advertisement. Ethics ap-proval was not required and descriptive statistics were calculated for all variables.


Our search resulted in 8.080 videos, of which 200 were reviewed, and 159 videos uploaded on YouTube between 2008 and 2016 were analysed. Videos were categorized as very useful (6.29%), moderately useful (16.35%), somewhat useful (24.35%), and not useful (52.83%). The video source revealed the following classification: organizational, n = 76; professional, n = 11; personal, n= 46; and advertisement, n = 26.


YouTube's Brazilian videos on diabetic foot care are popular, with varied sources and content. However, most of their content is not useful. Therefore, YouTube videos in Portuguese cannot be considered a good source of information about diabetes foot care.
