背景:地中海饮食与几种心脏代谢疾病的风险降低有关。科学文献中缺乏对地中海饮食的明确定义以及互联网上营养错误信息的增加表明,寻求基于网络的地中海饮食信息的消费者可能会感到困惑。
目的:我们在有影响力的社交媒体平台上对有关地中海饮食的信息进行了社交媒体内容分析,TikTok,检查关于饮食的公共话语,并确定潜在的错误信息领域。然后,我们在健康促进的背景下分析了这些发现,以确定使用TikTok促进地中海饮食健康生活的潜在挑战和机遇。
方法:下载并定性检查了搜索#mediterraneandiet标签后首次出现的202个TikTok帖子。岗位特点和特点,海报信息,并在各个帖子中提取和合成了参与度指标。根据海报报告的凭证,将职位分为由卫生专业人员创建的职位和由非卫生专业人员创建的职位。除了整个样本的描述性统计之外,我们使用卡方检验比较了专业人士和非专业人士为内容创建的帖子。
结果:TikTok帖子的内容各不相同,但是,由卫生专业人员与非专业人员开发的帖子更有可能提供地中海饮食的定义(16/106,15.1%vs2/96,2.1%;P=.001),使用科学引用来支持索赔(26/106,24.5%vs0/96,0%;P<.001),并讨论特定营养素(33/106,31.1%vs6/96,6.3%;P<.001)和与饮食相关的疾病(27/106,25.5%vs5/96,5.2%;P<.001)与非健康专业人员创建的职位相比。
结论:社交媒体有望成为推广地中海饮食的场所,但是在这项研究中发现的信息的可变性突出表明,在开发使用新媒体结构的地中海饮食干预措施时,需要对饮食及其成分进行明确的定义。
BACKGROUND: The Mediterranean diet has been linked to reduced risk for several cardiometabolic diseases. The lack of a clear definition of the Mediterranean diet in the scientific literature and the documented proliferation of nutrition misinformation on the internet suggest the potential for confusion among consumers seeking web-based Mediterranean diet information.
OBJECTIVE: We conducted a social media content analysis of information about the Mediterranean diet on the influential social media platform, TikTok, to examine public discourse about the diet and identify potential areas of misinformation. We then analyzed these findings in the context of health promotion to identify potential challenges and opportunities for the use of TikTok in promoting the Mediterranean diet for healthy living.
METHODS: The first-appearing 202 TikTok posts that resulted from a search of the hashtag #mediterraneandiet were downloaded and qualitatively examined. Post features and characteristics, poster information, and engagement metrics were extracted and synthesized across posts. Posts were categorized as those created by health professionals and those created by nonhealth professionals based on poster-reported credentials. In addition to descriptive statistics of the entire sample, we compared posts created by professionals and nonprofessionals for content using chi-square tests.
RESULTS: TikTok posts varied in content, but posts that were developed by health professionals versus nonprofessionals were more likely to offer a definition of the Mediterranean diet (16/106, 15.1% vs 2/96, 2.1%; P=.001), use scientific citations to support claims (26/106, 24.5% vs 0/96, 0%; P<.001), and discuss specific nutrients (33/106, 31.1% vs 6/96, 6.3%; P<.001) and diseases related to the diet (27/106, 25.5% vs 5/96, 5.2%; P<.001) compared to posts created by nonhealth professionals.
CONCLUSIONS: Social media holds promise as a venue to promote the Mediterranean diet, but the variability in information found in this study highlights the need to create clear definitions about the diet and its components when developing Mediterranean diet interventions that use new media structures.
