ABSTRACT
OBJECTIVES: Lyme disease is the most common tick-borne disease. People seek health information on Lyme disease from YouTube™ videos. In this study, we investigated if the contents of Lyme disease-related YouTube™ videos varied by their sources. METHODS: Most viewed English YouTube™ videos (n = 100) were identified and manually coded for contents and sources. RESULTS: Within the sample, 40 videos were consumer-generated, 31 were internet-based news, 16 were professional, and 13 were TV news. Compared with consumer-generated videos, TV news videos were more likely to mention celebrities (odds ratio [OR], 10.57; 95% confidence interval [CI], 2.13–52.58), prevention of Lyme disease through wearing protective clothing (OR, 5.63; 95% CI, 1.23–25.76), and spraying insecticides (OR, 7.71; 95% CI, 1.52–39.05). CONCLUSION: A majority of the most popular Lyme disease-related YouTube™ videos were not created by public health professionals. Responsible reporting and creative video-making facilitate Lyme disease education. Partnership with YouTube™ celebrities to co-develop educational videos may be a future direction.

OBJECTIVES: The purpose of this study was to describe the source, length, number of views, and content of the most widely viewed Zika virus (ZIKV)-related YouTube videos. We hypothesized that ZIKV-related videos uploaded by different sources contained different content. METHODS: The 100 most viewed English ZIKV-related videos were manually coded and analyzed statistically. RESULTS: Among the 100 videos, there were 43 consumer-generated videos, 38 Internet-based news videos, 15 TV-based news videos, and 4 professional videos. Internet news sources captured over two-thirds of the total of 8 894 505 views. Compared with consumer-generated videos, Internet-based news videos were more likely to mention the impact of ZIKV on babies (odds ratio [OR], 6.25; 95% confidence interval [CI], 1.64 to 23.76), the number of cases in Latin America (OR, 5.63; 95% CI, 1.47 to 21.52); and ZIKV in Africa (OR, 2.56; 95% CI, 1.04 to 6.31). Compared with consumer-generated videos, TV-based news videos were more likely to express anxiety or fear of catching ZIKV (OR, 6.67; 95% CI, 1.36 to 32.70); to highlight fear of ZIKV among members of the public (OR, 7.45; 95% CI, 1.20 to 46.16); and to discuss avoiding pregnancy (OR, 3.88; 95% CI, 1.13 to 13.25). CONCLUSIONS: Public health agencies should establish a larger presence on YouTube to reach more people with evidence-based information about ZIKV.

Inadequate bowel preparation prior to colonoscopy compromises the medical value of the procedure. The aim of this study is to explore the factors associated with pre-colonoscopy sub-optimal bowel preparation from the perspective of the physician. Using a cross-sectional study design, we examined the role of various factors thought to be associated with sub-optimal bowel preparation as reported by a sample of practicing Gastroenterologists across the United States. We conducted a survey among active members of the American College of Gastroenterology to assess Gastroenterologists' perceptions about barriers faced by the patients in the bowel preparation process. Descriptions of factors associated with sub-optimal bowel preparation prior to screening colonoscopy were identified and described, including health conditions, patient cognitive/ behavioral characteristics and medication use. Health conditions [including constipation and diabetes] and particular patient characteristics [including older age] were the most common perceived determinants of sub-optimal bowel preparation. Although some barriers to colonoscopy preparation [e.g., older age], cannot be modified, many are amenable to change through education. This study indicates the potential value of a personalized approach to bowel preparation, which addresses the specific needs of an individual patient like chronic constipation and diabetes and those with poor literacy skills or poor fluency in English. Development and evaluation of educational interventions to address these factors warrants investment
