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。
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, average 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 (OR) and 95% confidence intervals (CI) 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 vs. never) was positively associated with dietary risk behaviors, including frequent breakfast skipping (OR [95% CI]=1.20 [1.13, 1.28]), frequent nighttime eating (1.43 [1.33, 1.54]) and frequent intakes of fast foods (1.69 [1.58, 1.80]), SSBs (1.47 [1.30, 1.66]), and high-caffeine drinks (1.41 [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 compared with non-viewers (perceived \"no influence\" vs. non-viewers: OR [95% CI]=1.18 [1.10, 1.26] breakfast skipping; 1.15 [1.06, 1.24] nighttime eating; 1.40 [1.30, 1.50] fast foods; 1.22 [1.07, 1.38] SSBs; 1.28 [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.
