Human Papillomavirus (HPV) and Pap Smear Testing among HIV+ Women in La Romana, Dominican Republic, 2015-2016

Abstract

Background: Everyday approximately a billion viewers watch hundreds of millions of hours on YouTube. Currently YouTube videos are used as internet based media for dissemination of public health information. To characterize viewer engagement pattern, we measured viewership, viewer-preferences and viewer-responses to the HIV/AIDS awareness and prevention related videos on YouTube. Methods: We performed a search on YouTube (www.youtube. com) using the keywords 'HIV/AIDS awareness', 'HIV/AIDS prevention', and 'HIV/AIDS education. YouTube videos possessing 5000 viewership were selected for analysis. Viewer engagement was measured by recording total number of views, likes, dislikes, shares, and comments. Views per day were calculated by dividing total number of views by number of days since upload. Number of reaction was obtained by combining number of likes and dislikes. To assess differences in continuous variables across different categories, non-parametric Kruskal-Wallis test was used for non-normal distributions.
