Avaliação da qualidade dos vídeos sobre câncer de mama no Youtube: relevância para promoção da saúde da mulher

Abstract

Breast cancer is one of the main diseases that affect the health of women in the world. Although it is a disease with a high potential for mortality, the chances of survival increase considerably when the diagnosis is made early. Thus, strategies aimed at improving women's access to information on prevention are essential for the control of this type of cancer. As the online video platform “YouTube” has been widely accessed by the population to search for health information, the objective of this dissertation was to evaluate the quality of videos related to the topic of breast cancer. The videos were downloaded from October 11 to November 14, 2020 using the keyword "breast cancer". The first 200 most viewed videos were extracted for analysis. Videos longer than 15 minutes were excluded (N = 36); less than one minute (N = 03); and those that did not address content relevant to the topic (N = 03), leaving 158 videos for analysis. The data referring to the technical information were obtained through the analysis of the information contained in the description of the videos and the analysis of the content carried out by comparing the information contained in the videos with that described in the breast cancer control manuals of the Brazilian Ministry of Health. The majority (72%) of the analyzed videos are short and less than six minutes long and available on the platform for at least five years. These are widely viewed videos where the majority (73%) have up to 18,000 views and the majority (68%) are posted by self-reported accounts as health professionals. Most of these videos (73%) were created to disseminate information content to the layperson, although more than 90% of them did not present a definition of what breast cancer is, risk factors (87%), signs and symptoms (85%), primary prevention (85%), and tertiary prevention (64%). The focus of attention was secondary prevention being presented in 71.5% of the videos, however, less than 2% of them with correct information. In general, 53% of the videos were rated as bad or very bad, 40% as regular and only 7% as good or great. It is concluded that YouTube presents itself as a supporting tool in the process of educating women regarding the control of breast cancer, however, the evidence of limitations in the content of the videos, generates the need for greater performance by public agencies in the production and dissemination of quality information to the population.
