摘要
背景:在肥胖人群中，COVID-19的严重程度被放大，这可能通过提高对病情的了解和增加与体重相关的耻辱感，影响了主流媒体对该疾病的报道。目的:我们旨在测量2019冠状病毒病大流行第一年关键日期前后Facebook和Instagram上与肥胖相关的对话。方法:提取2020年1月28日(美国第一例COVID-19病例)、3月11日(宣布COVID-19全球大流行)、5月19日(主流媒体将肥胖与COVID-19联系在一起)和10月2日(美国前总统特朗普感染COVID-19，主流媒体最频繁提及肥胖)前后29天的公开Facebook和Instagram帖子。使用中断时间序列评估每日帖子和相应交互的趋势。每个平台上最常见的10个与肥胖相关的话题也被调查了。结果:在Facebook上，5月19日与肥胖相关的帖子和互动在2020年暂时增加(帖子+405,95% CI 166至645;互动+294,930,95% CI 125,986至463,874)和10月2日(帖子+639,95% CI 359至883;交互作用+182,814,95% CI为160,524至205,105)。在Instagram上，只有5月19日(+226,017,95% CI 107,323至344,708)和10月2日(+156,974,95% CI 89,757至224,192)的互动在2020年暂时增加。在对照组中没有观察到类似的趋势。五个最常见的话题重叠(COVID-19、减肥手术、减肥故事、儿童肥胖和睡眠);每个平台特有的其他主题包括饮食时尚、食物组和标题党。结论:社交媒体上与肥胖相关的公共健康新闻的对话激增。谈话中既有临床内容，也有商业内容，准确性可能令人怀疑。我们的研究结果支持这样一种观点，即重大公共卫生公告可能与社交媒体上与健康相关的内容(真实或不真实)的传播同时发生。
Obesity-Related Discourse on Facebook and Instagram Throughout the COVID-19 Pandemic: Comparative Longitudinal Evaluation.
Background: COVID-19 severity is amplified among individuals with obesity, which may have influenced mainstream media coverage of the disease by both improving understanding of the condition and increasing weight-related stigma.
Objective: We aimed to measure obesity-related conversations on Facebook and Instagram around key dates during the first year of the COVID-19 pandemic.
Methods: Public Facebook and Instagram posts were extracted for 29-day windows in 2020 around January 28 (the first US COVID-19 case), March 11 (when COVID-19 was declared a global pandemic), May 19 (when obesity and COVID-19 were linked in mainstream media), and October 2 (when former US president Trump contracted COVID-19 and obesity was mentioned most frequently in the mainstream media). Trends in daily posts and corresponding interactions were evaluated using interrupted time series. The 10 most frequent obesity-related topics on each platform were also examined.
Results: On Facebook, there was a temporary increase in 2020 in obesity-related posts and interactions on May 19 (posts +405, 95% CI 166 to 645; interactions +294,930, 95% CI 125,986 to 463,874) and October 2 (posts +639, 95% CI 359 to 883; interactions +182,814, 95% CI 160,524 to 205,105). On Instagram, there were temporary increases in 2020 only in interactions on May 19 (+226,017, 95% CI 107,323 to 344,708) and October 2 (+156,974, 95% CI 89,757 to 224,192). Similar trends were not observed in controls. Five of the most frequent topics overlapped (COVID-19, bariatric surgery, weight loss stories, pediatric obesity, and sleep); additional topics specific to each platform included diet fads, food groups, and clickbait.
Conclusions: Social media conversations surged in response to obesity-related public health news. Conversations contained both clinical and commercial content of possibly dubious accuracy. Our findings support the idea that major public health announcements may coincide with the spread of health-related content (truthful or otherwise) on social media.
