Table 1_Association between food-related media content and the eating behaviors of Korean adults according to household type.docx

BackgroundSociocultural changes and the proliferation of digital platforms have led to the increasing popularity of food-related content in Korea, including Mukbang, Cookbang, and Sulbang. Despite concerns that such content may influence eating habits, research focusing on adults is limited. Therefore, this study examined the association between media content and eating behaviors, stratified by household type, while considering the living environment. MethodsData were derived from an online survey conducted by the National Cancer Center, comprising responses from 1,270 participants divided in a 1:1 ratio based on whether they watched food-related content. The participants reported their eating behaviors and viewing habits. Multivariable logistic regression was employed to identify relationships after adjusting for sociodemographic variables, with analyses stratified by household type. ResultsThe analysis results showed that in multi-person households, viewing all content types were significantly associated with late-night eating and delivery/take-out meal consumption, with some also related to the frequency of dining out. Conversely, in single-person households, significantly positive associations were exclusively found between Mukbang viewing and late-night eating as well as delivery/take-out meal consumption; Cookbang and Sulbang did not yield statistically significant results. In stratified analysis, more subgroups exhibited associations with eating behaviors, regardless of content type among multi-person households. ConclusionThe findings suggest that viewing food-related content is linked to dietary behaviors, with effects varying depending on household type. Furthermore, acknowledging the impact of such content on eating behaviors to explore means of utilizing it positively to foster healthy eating habits is imperative.一、研究背景 社会文化变迁与数字平台的普及，推动韩国饮食相关内容（含Mukbang、Cookbang、Sulbang）热度持续攀升。尽管有观点担忧此类内容可能影响大众饮食行为，但针对成年人的相关研究仍较为匮乏。为此，本研究结合居住环境，按家庭类型分层，探讨媒体饮食内容与进食行为之间的关联。 二、研究方法 本研究数据源自韩国国家癌症中心（National Cancer Center）开展的在线调查，共回收1270份有效问卷，按是否观看饮食相关内容以1:1比例分为两组。参与者需报告自身进食行为与观看习惯。本研究采用多变量logistic回归分析，在控制社会人口学变量后明确两者关联，并按家庭类型开展分层分析。 三、研究结果 分析结果显示，在多人家庭中，观看各类饮食相关内容均与深夜进食、外卖/外带餐食摄入存在显著关联，部分内容类型还与外出就餐频次相关。与之相反，在单人家庭中，仅观看Mukbang与深夜进食及外卖/外带餐食摄入存在显著正向关联；Cookbang与Sulbang则未呈现统计学显著性。分层分析表明，在多人家庭中，无论何种内容类型，更多亚组均展现出与进食行为的关联。 四、研究结论 本研究结果表明，观看饮食相关内容与饮食行为存在关联，且其影响效应因家庭类型而异。此外，认清此类内容对饮食行为的影响，并探索积极利用该内容以培育健康饮食习惯，实属必要之举。
