The Reliability and Quality of Short Videos as a Source of Dietary Guidance for Inflammatory Bowel Disease: Cross-sectional Study
ABSTRACT
Background:
Dietary management is considered one of the potential adjunctive treatments in IBD. The short video sharing platforms has enabled patients to obtain dietary advice more convenient. However, accessing useful resources while avoiding misinformation is not an easy task for most patients.
Objective:
This study aimed to evaluate the quality of the information in IBD diet-related videos on Chinese short video sharing platforms.
Methods:
We collected and extracted information from a total of 125 video samples related to IBD diet on 3 Chinese short video sharing platforms with the most users, Tiktok, bilibili, and Kwai. Two independent physicians evaluated each video in terms of content comprehensiveness, quality (rated by Global Quality Score), and reliability (rated by modified DISCERN tool). Finally, comparative analyses of the videos from different sources were conducted.
Results:
The videos were classified into six groups based on the identity of the uploaders, which included three kinds of medical professionals (ie, gastroenterologists, non-gastroenterologists, and clinical nutritionists) and three types of non-medical professionals (ie, non-profit organizations, individual science communicators, and IBD patients). The overall quality of the videos was poor. Further group comparisons demonstrated that videos from medical professionals were more instructive in terms of content comprehensiveness, quality, and reliability than those from non-medical professionals. Moreover, IBD diet-related recommendations from clinical nutritionists and gastroenterologists were of better quality than those from non-gastroenterologists, while recommendations from non-profit organizations did not seem to be superior to other groups of uploaders.
Conclusions:
The videos were classified into six groups based on the identity of the uploaders, which included three kinds of medical professionals (ie, gastroenterologists, non-gastroenterologists, and clinical nutritionists) and three types of non-medical professionals (ie, non-profit organizations, individual science communicators, and IBD patients). The overall quality of the videos was poor. Further group comparisons demonstrated that videos from medical professionals were more instructive in terms of content comprehensiveness, quality, and reliability than those from non-medical professionals. Moreover, IBD diet-related recommendations from clinical nutritionists and gastroenterologists were of better quality than those from non-gastroenterologists, while recommendations from non-profit organizations did not seem to be superior to other groups of uploaders.
