Association between mukbang and cookbang watching and obesity in Korean adolescents: a cross-sectional study.
Article in Korean journal of community nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesIn this study, the association between the frequency of watching mukbang/ cookbang (online eating and cooking broadcasts) and obesity in Korean adolescents was investigated using data from the 21st (2025) Korea Youth Risk Behavior Web-based Survey.
methodsThe subjects were 52,624 middle- and high-school students, who were classified based on watching frequency as follows: non-watchers, monthly watchers, and weekly watchers (≥ 1 time/week). Changes in the dietary behavior of the watchers (n = 34,375) were assessed. Obesity was defined as a sex- and age-specific body mass index ≥ 95th percentile as per the 2017 Korean Children and Adolescents Growth Standard. Complex sample multiple logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs), controlling for sociodemographic, health-related, and dietary covariates. Sex-stratified analyses and P for trend tests were also conducted.
resultsOverall, 65.3% of students watched mukbang/cookbang in the past year. The weekly watchers had significantly higher odds of obesity than the non-watchers (aOR = 1.09, 95% CI: 1.02-1.16; P for trend = 0.011). Sex-stratified analyses showed a positive association in boys (aOR = 1.20, 95% CI: 1.11-1.30), but an inverse association in girls (aOR = 0.86, 95% CI: 0.77-0.97). Among the watchers, the "eating quickly" group had the highest odds for obesity (aOR = 1.54, 95% CI: 1.31-1.82), whereas the "eating night snacks/ snacks" (aOR = 0.85, 95% CI: 0.74-0.98) and "eating spicy or highly flavored foods" (aOR = 0.85, 95% CI: 0.73-0.99) groups were associated with lower odds of obesity.
conclusionRegular mukbang/cookbang viewing was significantly associated with adolescent obesity. A media-induced "fast eating rate" was identified as a potential behavioral pathway linked to higher obesity risk, suggesting that adolescent obesity prevention programs should incorporate media literacy and behavioral interventions that promote slower eating.
