Abstract

BACKGROUND/AIMS: Despite a broad call for biobanks to use social media, data is lacking regarding the capacity of social media tools, especially advertising, to engage large populations on this topic. METHODS: We used Facebook advertising to engage Michigan residents about the BioTrust for Health.

Interactions included 516 'likes' and 30 photo contest entries. Cost per outcome ranged from
