Engaging a state: Facebook comments on a large population biobank.

ABSTRACT: Scholarship on newborn screening, dried bloodspot retention, and large population biobanking call consistently for improved public engagement. Communication with participants likely occurs only in the context of collection, consent, or notification, if at all. We ran an 11-week advertising campaign to inform Michigan Facebook users unlikely to know that their or their children's dried bloodspots (DBSs) were stored in a state biobank. We investigated the pattern and content of comments posted during the campaign, focusing on users' questions, attitudes and concerns, and the role the moderator played in addressing them. We used Facebook data to quantitatively assess engagement and employed conventional content analysis to investigate themes, attitudes, and social dynamics among user and moderator comments. Five ad sets elicited comments during campaign weeks 4-8, reaching ?800,000 Facebook users ($6000). Gravitating around broad, underlying ethical, legal, and social issues, 180 posts from 129 unique users related to newborn screening or biobanking. Thirty six conveyed negative attitudes and 33 conveyed positive attitudes; 53 posed questions. The most prevalent themes identified were consent, privacy, bloodspot use, identifiability, inclusion criteria, research benefits, (mis)trust, genetics, DBS destruction, awareness, and the role of government. The moderator's 81 posts were responsive-answering questions, correcting or clarifying information, or providing information about opting out. Facebook ad campaigns can improve engagement by pushing out relevant content and creating dynamic, responsive, visible forums for discussion. Reduced control over messaging may be worth the trade-off for creating accessible, transparent, people-centered engagement on public health issues that are sensitive and complex.

Project description:Large population biobanks, important resources for genomic research, also present ethical challenges. The Michigan BioTrust for Health makes dried bloodspots (DBS) leftover from newborn screening, including ~4.5 million collected before 2010 without written consent, available for health research. Absent prospectively gathered consent and/or current engagement with 18- to 29-year olds, little is known about opinions and beliefs from this age group about use of the bloodspots for research. We engaged 2,101 students-BioTrust participants and their peers-at information booths at 20 college campuses across the state to educate youth about the BioTrust and gather information about consent preferences and about hopes and concerns about this public health program. We surveyed student stakeholder DBS research consent preferences and fielded a "postengagement" survey to gauge the attitudes of participants and to evaluate the campus engagement. The most prevalent themes in open-ended comments were support for biobank research and concern that Michiganders are not aware of their participation. While 78 % of students said they would, if asked, opt in to the BioTrust, half of these preferred to be contacted each time a researcher sought to use their DBS. Students reported great interest in the topic and strong likelihood to share what they had learned. BioTrust participants are interested in learning about their role in an initiative whose goals they widely support. Public engagement is particularly important to biobank participants who, absent traditional consent practices, are unaware of their participation. Health-fair style engagements were effective for targeting college-aged stakeholders, communicating complex messages, and likely increasing knowledge. Retrospective biobanks and biobanks that collect proxy consent need policies to respect those who would opt out and will need resources to educate participants and conduct community outreach that is a safeguard to public trust.

Project description:BackgroundPhysical activity has not been objectively measured in prospective cohorts with sufficiently large numbers to reliably detect associations with multiple health outcomes. Technological advances now make this possible. We describe the methods used to collect and analyse accelerometer measured physical activity in over 100,000 participants of the UK Biobank study, and report variation by age, sex, day, time of day, and season.MethodsParticipants were approached by email to wear a wrist-worn accelerometer for seven days that was posted to them. Physical activity information was extracted from 100Hz raw triaxial acceleration data after calibration, removal of gravity and sensor noise, and identification of wear / non-wear episodes. We report age- and sex-specific wear-time compliance and accelerometer measured physical activity, overall and by hour-of-day, week-weekend day and season.Results103,712 datasets were received (44.8% response), with a median wear-time of 6.9 days (IQR:6.5-7.0). 96,600 participants (93.3%) provided valid data for physical activity analyses. Vector magnitude, a proxy for overall physical activity, was 7.5% (2.35mg) lower per decade of age (Cohen's d = 0.9). Women had a higher vector magnitude than men, apart from those aged 45-54yrs. There were major differences in vector magnitude by time of day (d = 0.66). Vector magnitude differences between week and weekend days (d = 0.12 for men, d = 0.09 for women) and between seasons (d = 0.27 for men, d = 0.15 for women) were small.ConclusionsIt is feasible to collect and analyse objective physical activity data in large studies. The summary measure of overall physical activity is lower in older participants and age-related differences in activity are most prominent in the afternoon and evening. This work lays the foundation for studies of physical activity and its health consequences. Our summary variables are part of the UK Biobank dataset and can be used by researchers as exposures, confounding factors or outcome variables in future analyses.
