Abstract: BACKGROUND: YouTube is among the most highly used internet video sharing platforms worldwide. OBJECTIVE: The aim in this study was to conduct a social media content analysis of Dietary Approaches to Stop Hypertension (DASH) diet videos on YouTube. METHODS: Specific search parameters were input into YouTube, and 101 videos were evaluated for quality and viewer exposure/engagement metrics independently by 3 content experts using the DISCERN instrument, a 16-item instrument designed to assess quality, reliability, and dependability of an online source. Scores were aggregated for analysis. RESULTS: The majority (n = 69, 68.3%) of the videos were categorized as educational and came from a nonprofit source (n = 35, 34.7%). Although multiple speakers were the most frequent speaker type (n = 30, 29.7%), influencers/actors, dietitians, and healthcare providers were relatively equally distributed across the category (25.7%, 22.8%, and 21.8% respectively). Correlation analysis evaluating video's views, comments, and likes indicates that these video metrics are not correlated with video quality. However, the length of video was moderately and positively associated ( P = .01) with the 4 DISCERN parameters of quality. CONCLUSION: Study findings suggest that videos on DASH diet offered via YouTube could potentially be an inexpensive venue to promote healthful dietary practices and educate clients. Existing YouTube content on DASH diet demonstrates significant variability in quality ratings based on DISCERN. Providers should direct individuals to engage with high-quality educational DASH diet videos on YouTube that are created with qualified health professionals and are shared by reputable institutions.
