Title of Talk

Social Media for Lifestyle Health



As social media captures an increasing portion of our lives, it is becoming an invaluable resource for understanding lifestyle diseases such as obesity and diabetes. This section will cover techniques for understanding culture around food and nutrition using Instagram, Twitter, and Facebook Advertising API. In particular, content meta-data will be analyzed using topic discovery, grounded content coding, and enriched using outside resources. Further, network analysis will show the homophily in nutritional behavior, as well as the flows of information (and potential misinformation) in social media. Finally, we will glimpse population-level analytics available through the advertising platforms.
