Update on the Quality and Health Literacy Demand of Diet-Related Videos on YouTube for People With Polycystic Kidney Disease.

OBJECTIVE: To describe the quality and health literacy demand of publicly available diet-related videos on YouTube for people with polycystic kidney disease (PKD). DESIGN AND METHODS: This desk-based content analyzed involved a comprehensive search of YouTube using key words relating to the dietary management of people with PKD. The health literacy demand was evaluated using the Patient Education Material Assessment Tool (PEMAT) for audio-visual materials. A PEMAT score of >70% is indicative of videos that are understandable and actionable. RESULTS: A total of 15 videos were evaluated (median 1.28 minutes duration (range: 55 seconds-81 minutes). The majority were produced by reputable sources (such as a PKD-related charity (n = 12) or a nephrologist (n = 2). The quality of the videos was high with the majority (14/15) providing evidence-based advice. The understandability and actionability of the videos were considered low (median PEMAT score 67% (interquartile range: 51.4-81.7) and 66.83% (interquartile range: 50-67), respectively. CONCLUSION: There has been a small increase in the number of diet-related videos for people with PKD in the past 5 years. The majority provide evidence-based information, which is also a substantial improvement since the last analysis in 2015. Unfortunately, the health literacy demand of these resources remains suboptimal, and future work should be directed to improving the understandability and actionability of videos.

Systematic review with meta-analysis: dietary intake in adults with inflammatory bowel disease.

BACKGROUND: Poor dietary intake is associated with the development of malnutrition, micronutrient deficiencies, anaemia and osteoporosis in individuals with inflammatory bowel disease. While trials are underway to manipulate the diet of people with IBD, there has been no comprehensive systematic review of the dietary intake of adults with IBD. AIMS: To conduct a systematic evaluation and meta-analysis of the dietary intake of adults with IBD, including macronutrients, micronutrients and food group data. METHODS: CINAHL, Embase, Medline and Scopus were searched from 1 January 2000 to 25 September 2020 for cohort, case-control or cross-sectional studies that reported usual dietary intake in adults. Data were pooled and reported as weighted mean intake for: all adults with IBD; Crohn's disease; ulcerative colitis; active disease; remission; males; females. A random-effects meta-analysis model compared intake with healthy individuals. RESULTS: Forty studies were identified and 19 were included in the meta-analysis. All subgroups of adults with IBD consumed inadequate energy (mean intake in adults with IBD 1980 ± 130 kcal), fibre (14 ± 4 g), folate (246 ± 33 mg) and calcium (529 ± 114 mg) per day. Intake of breads and cereals, legumes, fruit, vegetables and dairy were inadequate. Compared to healthy individuals, adults with IBD consume significantly less dietary fibre (SMD -0.59; 95% CI: -0.73, -0.46). CONCLUSIONS: This review provides improved clarity about the dietary intake of adults with IBD. Future attention is required to improve diet quality and increase understanding of factors influencing dietary intake in IBD.
