Older adults' exposure to and posting of health-related messages on Facebook by chronic health condition status.

Objective: Older adults may be particularly interested in health-related content on Facebook, especially those who have chronic health conditions. The purpose of this study was to compare older adult Facebook users with and without a chronic health condition on their frequency of posting and exposure to health-related content.

Methods: Participants, recruited via Qualtrics, were regular Facebook users aged 50 + years. Participants were asked separately if they had seen, posted, and shared: Health-related information; about others'/their own health behaviors (e.g., exercise); and about others'/their own medical condition. Six logistic regression models, controlling for demographics and Facebook login frequency, were run to assess whether viewing and/or posting health-related messages differed by chronic health condition status.

Results: Respondents ( = 697; 77.9% female) were on average 61.2 (SD = 7.9) years old and ( = 625; 89.7%) were White. One-half reported a chronic health condition ( = 351; 50.4%). In adjusted models, those with a chronic health condition had a higher likelihood of seeing posts containing health information (OR = 1.41; 95% CI: 1.04, 1.93) and about others' medical conditions (OR = 1.67; 95% CI: 1.22, 2.27) at least once a month compared to those with no chronic health conditions. People with and without chronic health conditions did not differ in terms of how often they see others' post about health behaviors. Those with a chronic health condition had a higher likelihood of posting or sharing health information (OR = 1.67; 95% CI: 1.22, 2.27), posting about their own health behaviors (OR = 1.55; 95% CI: 1.00, 2.44;  = 0.048), and about their health condition (OR = 1.96; 95% CI: 1.17, 3.27) at least once a month.

Conclusion: Most older adults on Facebook are exposed to and post multiple forms of health-related content. Therefore, Facebook may be an appropriate channel for conducting health-related communication targeting older adults.
