Quality and Reliability of YouTube Videos on Myocardial Infarction: A Cross-Sectional Study

INTRODUCTION

This study aims to assess the quality and reliability of the disease information available on YouTube (www.youtube.com) about "heart attacks" or myocardial infarctions, using a Global Quality Score (GQS) for quality, a DISCERN score for reliability, and a Video Power Index (VPI) for popularity.

METHODOLOGY

In this cross-sectional observational study, the YouTube videos were analyzed in terms of the type of uploader, content, and other factors. The GQS, DISCERN score, and Video Power Index (VPI) were utilized to assess the quality, reliability, and popularity of the information, respectively.

RESULTS

The majority of the videos (78.44%) were uploaded over a year ago. Only 33.34% and 7.84% were uploaded by doctors and healthcare organizations, respectively. Around 72.55% of the videos contained information about symptoms, 66.67% discussed the causes, 52.94% covered treatment, and 47.06% focused on prevention. Additionally, 41.18% provided details on investigations, while only 19.61% touched upon mortality. Patient-created videos accounted for 19.61% of the content, and 15.69% of the videos included promotional material.

CONCLUSION

The main outcome of our study indicates that the YouTube videos examined regarding myocardial infarctions exhibit high-quality content, as supported by a higher average GQS score. The consistent quality of information discovered in our study suggests that YouTube can serve as an additional platform for sharing knowledge and educating individuals about this important health condition. By raising awareness and delivering accurate information, these videos can help in early detection, prevention, and better outcomes for individuals who are at risk of experiencing a myocardial infarction.

Obesity: An Instagram Analysis

Introduction Although the pathophysiology of obesity is widely recognized, its psychological and social aspects have received more attention in treatment and prevention. Social media technological advancements offer a quicker, more accessible, and broader platform for the dissemination of information. Hence, social media may significantly impact eating habits and body image development in children and adolescents, potentially turning into a risk factor for obesity if the behaviors being pushed are not consistent with a healthy lifestyle. Aim This study aims to evaluate the quality and reliability of content being circulated on Instagram related to the disease "obesity." Methods A cross-sectional observational study was conducted virtually over a period of ten days. Six hashtags related to the disease "obesity" were screened. Posts in the languages "English" or "Hindi" containing information about the disease "obesity" were included in the study. A questionnaire was made to assess these posts based on various pre-determined categories: type of post, type of information circulated, quality, reliability, and correctness. Results After applying the inclusion criteria, 420 posts were included in our study. 84% of the relevant posts were images/posts, and 15% were videos. Only 17% were posted by doctors, while the health and wellness industry posted around 54.52%. Survivors/persons suffering from the disease contributed to 13.81%, while that from dietitians was 6.43%, and that from new agencies was only 1.19%. The number of correct posts by doctors, nurses, and hospitals was 54.93%, and others were 37.7%. The posts by doctors, nurses, and hospitals were more reliable compared to others (statistically significant p<0.05). Conclusion This study highlights the need for continued monitoring and evaluation of the social media platform Instagram for the spread of healthcare information.
