Sharing behaviors of older adults in online health information: A systematic literature review.

Understanding the motivations of older adults' online behaviors, representing an increasingly significant segment of social media users, is essential for bolstering public health literacy and wellness. As these individuals turn more to online resources for health management and social engagement, comprehending their rationale for sharing health information online becomes imperative. Practical strategies and interventions are urgently needed to improve eHealth literacy and the ability of older adults to identify trusted online information, thereby reducing the risks posed by misinformation to their health. This study evaluates older adults' motivations for sharing health information online. Understanding why they engage in this sharing behavior is crucial, as their motivations can range from seeking to build social connections to helping others manage their health and well-being. A systematic literature review was conducted using the Web of Science, Scopus, and Pubmed databases while adhering to the PRISMA. A total of 5247 articles were yielded and screened, where 16 articles were included according to explicit inclusion and exclusion criteria. Qualitative content analysis identified three critical motivations among older adults: perceived technological competence and self-efficacy, beliefs and attitudes, and social relationships and support. Additionally, the accuracy and credibility of information significantly influenced the sharing of health misinformation. This review highlights a gap in literature specifically focusing on older adults' information behavior and suggests future research to improve their health management and social support, offering new insights for health communicators to develop effective health promotion initiatives.
