Troubling expertise: social media and young people's sexual health

Social media are integral to young people's everyday lives, and sexual health promotion strategies seek to capitalise on this. Drawing from recent health promotion research and digital media ethnographies, this article considers research discourses of social media use by young people and health professionals. While health promotion commonly engages with social media as a 'setting' for the dissemination of static information, this neglects the participatory aspects of social media and overlooks young people's digital media competencies. Focus groups with young people further highlight these competencies, the centrality of friendship in social media, and the stigma of sharing formal sexual health information. Considering these literature and data, this article draws from post-structural theories of knowledge to consider how formal 'expertise' is leveraged through the subjugation of young people's knowledge, and how this is problematic for sexual health promotion seeking to engage with young people through social media.
