Social media, knowledge translation, and action on the social determinants of health and health equity: A survey of public health practices.

The growth of social media presents opportunities for public health to increase its influence and impact on the social determinants of health and health equity. The National Collaborating Centre for Determinants of Health at St. Francis Xavier University conducted a survey during the first half of 2016 to assess how public health used social media for knowledge translation, relationship building, and specific public health roles to advance health equity. Respondents reported that social media had an important role in public health. Uptake of social media, while relatively high for personal use, was less present in professional settings and varied for different platforms. Over 20 per cent of those surveyed used Twitter or Facebook at least weekly for knowledge exchange. A lesser number used social media for specific health equity action. Opportunities to enhance the use of social media in public health persist. Capacity building and organizational policies that support social media use may help achieve this.
