Purpose: The study aimed to reveal the association between the eating show or cooking show watching behavior and dietary habits of Korean adolescents, and also find out other factors related to their dietary habits. Methods: Among the total of 1,500 nationally representative samples with the age of over 15, we included 318 adolescents who have ever watched eating shows or cooking shows through the internet, as the study population. Information regarding the study was obtained through an online survey, which was conducted in the second half of the year 2019. Multiple linear regression analysis was conducted, with the outcome variable of Mini Dietary Assessment score, which indicates the overall dietary quality. Results: The frequency of watching and the reason for watching were factors related to the overall dietary habits of adolescents. Compared to the reference group, which is the group watching less than once a month, the dietary scores of groups watching ‘more than once a month less than once a week’(B=-1.84, β=-0.16, p<0.05), ‘more than once a week less than every day’(B=-2.03, β=-0.21, p<0.01), and ‘every day’(B=-2.56, β=-0.19, p<0.01) were low. For the reason of watching, ‘because the video is interesting’(B=-1.39, β=-0.14, p<0.01) and ‘for vicarious pleasure’(B=1.07, β=0.11, p<0.05) was associated with dietary habits. For other factors, living status (compared to living with family, living alone: B=-2.89, β=-0.13, p<0.05), residence (compared to living in urban area, rural area: B=2,68, β=0.17, p<0.01) and self-rated health (B=0.64, β=0.11, p<0.05), stress (B=0.78, β=0.14, p<0.05) and depression levels (B=-0.86, β=-0.19, p<0.01), a healthy diet-friendly environment, related to the people around(B=1.13, β=0.17, p<0.01) were associated with adolescents' dietary habits. Conclusions: The more frequent watching eating shows or cooking shows, the worse the dietary habits. For the reason for watching, ‘watching because the video is interesting’ was associated with an unhealthy diet, but ‘watching for vicarious pleasure’ was associated with a healthy diet. The results of this study are expected to be used as the basis for the development of nutrition education programs and for policies to prevent obesity for adolescents.
