Older adults and online health misinformation: a systematic literature review

As older adults increasingly rely on the internet for health-related information, concerns about their vulnerability to online health misinformation have intensified. This systematic literature review synthesizes findings from 26 empirical studies published between 2000 and 2024 to examine how older adults interact with health misinformation in digital contexts. The review identifies a complex interplay of factors contributing to their susceptibility, including cognitive decline, gaps in digital and health literacy, emotional and psychological influences, and the role of social relationships. However, most studies lack theoretical grounding, platform-specific analysis, and geographical diversity. Conceptual inconsistencies and a COVID-19 research bias further limit generalizability. The review calls for clearer definitions, interdisciplinary approaches, and targeted interventions to address this urgent public health issue and provide a foundation for designing more targeted and effective interventions.
