BACKGROUND
Studies have shown that prolonged smartphone use is associated with dietary risk behaviors among adolescents. However, little is known about whether the exposure to food-related online media contents, such as mukbang (eating broadcast) and cookbang (cooking broadcast), is associated with unhealthy dietary behaviors, independent of overall duration of smartphone use.
OBJECTIVES
This study investigated the associations between the frequency of mukbang/cookbang watching and dietary risk behaviors among Korean adolescents, using nationally representative survey data.
METHODS
In this cross-sectional study, we examined the data from 50,044 middle and high school students in the Korea Youth Risk Behavior Web-based Survey 2022. Participants reported their frequency of mukbang/cookbang watching, mean duration of smartphone use, frequency of breakfast eating, frequency of nighttime eating, and intakes of fast foods, sugar-sweetened beverages (SSBs), and high-caffeine drinks. We performed multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between mukbang/cookbang watching and dietary risk behaviors, accounting for complex survey sampling and adjusting for potential confounders.
RESULTS
Frequent mukbang/cookbang watching (≥5 times/wk compared with never) was positively associated with dietary risk behaviors, including frequent breakfast skipping (OR: 1.20; 95% CI: 1.13, 1.28), frequent nighttime eating (OR: 1.43; 95% CI: 1.33, 1.54), and frequent intakes of fast foods (OR: 1.69; 95% CI: 1.58, 1.80), SSBs (OR: 1.47; 95% CI: 1.30, 1.66), and high-caffeine drinks (OR: 1.41; 95% CI: 1.33, 1.50), adjusting for duration of smartphone use. All mukbang/cookbang viewers, including those who perceived that mukbang/cookbang videos had "no influence" on their dietary behavior, had higher prevalence of dietary risk behaviors than nonviewers (perceived "no influence" compared with nonviewers-OR: 1.18; 95% CI: 1.10, 1.26, breakfast skipping; OR: 1.15; 95% CI: 1.06, 1.24, nighttime eating; OR: 1.40; 95% CI: 1.30, 1.50, fast foods; OR: 1.22; 95% CI: 1.07, 1.38, SSBs; OR: 1.28; 95% CI: 1.20, 1.37, high-caffeine drinks).
CONCLUSIONS
Our findings suggest that frequent mukbang/cookbang watching may be associated with unhealthy dietary behaviors among Korean adolescents.
背景
研究表明，长时间使用智能手机与青少年的饮食风险行为有关。然而，目前尚不清楚接触与食物相关的在线媒体内容（如吃播和烹饪直播）是否与不健康的饮食行为有关，而这些行为与智能手机使用的总时长无关。
目的
本研究使用全国代表性的调查数据，调查了韩国青少年观看吃播/烹饪直播的频率与饮食风险行为之间的关系。
方法
在这项横断面研究中，我们对来自韩国青少年风险行为网络调查 2022 年的 50044 名中学生和高中生的数据进行了分析。参与者报告了他们观看吃播/烹饪直播的频率、智能手机使用的平均时长、早餐食用频率、夜间进食频率，以及快餐、含糖饮料（SSB）和高咖啡因饮料的摄入量。我们采用多变量逻辑回归来估计观看吃播/烹饪直播与饮食风险行为之间的比值比（OR）和 95%置信区间（CI），同时考虑到复杂的抽样调查，并调整了潜在的混杂因素。
结果
频繁观看吃播/烹饪直播（每周≥5 次与从不观看相比）与饮食风险行为呈正相关，包括经常不吃早餐（OR：1.20；95%CI：1.13，1.28）、经常夜间进食（OR：1.43；95%CI：1.33，1.54），以及经常摄入快餐（OR：1.69；95%CI：1.58，1.80）、SSB（OR：1.47；95%CI：1.30，1.66）和高咖啡因饮料（OR：1.41；95%CI：1.33，1.50），同时还考虑了智能手机使用时间的影响。所有观看吃播/烹饪直播的人，包括那些认为吃播/烹饪视频对他们的饮食行为“没有影响”的人，比不观看的人更有可能出现饮食风险行为（感知“没有影响”的人相对于不观看的人-OR：1.18；95%CI：1.10，1.26，不吃早餐；OR：1.15；95%CI：1.06，1.24，夜间进食；OR：1.40；95%CI：1.30，1.50，快餐；OR：1.22；95%CI：1.07，1.38，SSB；OR：1.28；95%CI：1.20，1.37，高咖啡因饮料）。
结论
我们的研究结果表明，频繁观看吃播/烹饪直播可能与韩国青少年不健康的饮食行为有关。
