Digital health literacy emerges as a critical vulnerability among aging populations, potentially undermining evidence-based healthcare decisions at a life stage when medical interventions carry the highest stakes. This demographic gap in information quality assessment could accelerate health disparities and complicate clinical care for millions of older adults navigating complex medical decisions online. Analysis of digital behavior patterns reveals older adults encounter low-credibility health content at rates three times higher than younger demographics, with particular vulnerability to misleading information about chronic disease management, supplements, and alternative treatments. The disparity stems from distinct online navigation patterns, reduced familiarity with digital verification tools, and algorithmic targeting that exploits health anxieties common in aging populations. Social media platforms and search engines appear to amplify this exposure through recommendation systems that prioritize engagement over accuracy. This finding illuminates a dangerous intersection between population aging and digital health ecosystems. As healthcare increasingly moves online and older adults represent the fastest-growing internet user segment, their heightened susceptibility to health misinformation poses significant public health implications. The research suggests current digital literacy interventions fail to address age-specific vulnerabilities in health information evaluation. Unlike financial or general misinformation, health-related false claims can directly impact medical adherence, treatment choices, and preventive care decisions among those most vulnerable to serious health consequences. This represents more than an information problem—it's a patient safety crisis requiring targeted interventions in both digital platform design and geriatric health education approaches.
