Abstract

Objectives
This study was conducted to investigate the relationship between watching Mukbang (eating broadcasts) and dietary and health behavior in adults who watch Mukbang
Methods
The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, Mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing Mukbang , delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to Mukbang viewing time.
Results
The body weight of viewers was significantly higher whenMukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched Mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of Mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of Mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched Mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high Mukbang viewing time per week, the frequency of food delivery and night eating was high. When Mukbang viewing time was high, the viewer’s interest in health was low and the frequency of exercising too was low.
Conclusions
Viewers with high Mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.
