Abstract：
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.
OBJECTIVE: 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.

摘要：
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,鲜为人知的是，是否接触到与食品相关的在线媒体内容，如mukbang(饮食广播)和cookbang(烹饪广播)，与不健康的饮食行为有关，与智能手机使用的整体持续时间无关。
目的：这项研究调查了韩国青少年观看mukbang/cookbang的频率与饮食风险行为之间的关联，使用具有全国代表性的调查数据。
方法：在这项横断面研究中，我们检查了2022年韩国青年风险行为网络调查中50,044名中学生和高中生的数据。参与者报告了他们观看mukbang/cookbang的频率，智能手机使用的平均持续时间，吃早餐的频率，夜间进食的频率，和快餐的摄入量，含糖饮料（SSB），和高咖啡因饮料。我们进行了多变量逻辑回归，以估计mukbang/cookbang观看与饮食风险行为之间的关联的优势比（OR）和95％置信区间（CI）。考虑复杂的调查抽样和调整潜在的混杂因素。
结果：经常观看mukbang/cookbang（≥5次/周vs.从来没有)与饮食风险行为呈正相关，包括经常不吃早餐(OR[95%CI]=1.20[1.13，1.28])，经常夜间进食（1.43[1.33，1.54]）和经常摄入快餐（1.69[1.58，1.80]），SSB(1.47[1.30,1.66])，和高咖啡因饮料（1.41[1.33，1.50]），调整智能手机使用的持续时间。所有mukbang/cookbang观众，包括那些认为mukbang/cookbang视频对他们的饮食行为没有影响的人，与非观察者相比，饮食风险行为的患病率更高(感知“无影响”与非观众：或[95%CI]=1.18[1.10，1.26]不吃早餐；1.15[1.06，1.24]夜间进食；1.40[1.30，1.50]快餐；1.22[1.07，1.38]SSB；1.28[1.20，1.37]高咖啡因饮料）。
结论：我们的研究结果表明，经常观看mukbang/cookbang可能与韩国青少年的不健康饮食行为有关。
