Adherence
YouTube is not a reliable source of medical and health-related information, as aggregated evidence shows content quality is average to below-average and popularity metrics (views/likes) do not correlate with quality.
Do not use YouTube as your primary source for medical decisions. The platform's algorithm promotes popular content, which is often low-quality or misleading. If you must use YouTube, look for videos from verified, reputable institutions (e.g., major hospitals, professional societies) and cross-reference the information with a healthcare provider. Be skeptical of videos with high view counts but low medical detail.
YouTube is not a reliable source of medical and health-related information. YouTube’s popularity-driven metrics such as the number of views and likes should not be considered quality indicators.
Why this rating
Based on a systematic review of 202 papers analyzing ~22,300 videos, providing robust aggregate data, though heterogeneity in quality metrics limits meta-analysis.
