Digital health literacy gaps leave adults over 65 significantly more vulnerable to consuming unreliable medical information across social media platforms and search results. The exposure differential suggests age-related changes in information processing, source evaluation skills, and platform algorithm targeting may converge to create heightened misinformation risk. This vulnerability becomes particularly concerning given that older adults represent the demographic most likely to have multiple chronic conditions requiring complex medical decision-making. The pattern mirrors broader digital literacy challenges but carries unique health consequences when misinformation influences medication adherence, treatment choices, or preventive behaviors. Previous research has established that health misinformation can delay appropriate care and increase mortality risk, making this age-based disparity a serious public health consideration. The findings highlight an urgent need for targeted digital literacy interventions and platform design modifications that prioritize credible health sources for older users. Healthcare providers may need to proactively address online health information consumption with older patients, while family members could play crucial roles in helping evaluate digital health claims.
