Objectives: This study aimed to investigate the association between how often Korean adolescents watch Mukbang and Cookbang videos and their dietary habits. Methods: Data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 was analyzed for this study. The study included 51,850 middle and high school students and assessed various aspects, including demographics, frequency of watching Mukbang and Cookbang videos per week, dietary habits, health behaviors, and mental health factors. Results: Nearly a third (29.3%) of Korean adolescents watched Mukbang and Cookbang videos one to four times a week, while 13.5% watched them more than five times weekly. Females, those with lower academic achievement, and those from lower socioeconomic backgrounds were significantly more likely to be frequent viewers (P < 0.001). Increased viewing frequency was associated with poorer dietary habits. Adolescents who watched more frequently were less likely to eat breakfast and consume fruits and milk, while their consumption of fast food, high-caffeine drinks, sugary drinks, and late-night snacks increased (P < 0.001). Higher viewing frequency correlated with increased feelings of stress, depression, and loneliness (P < 0.001). Logistic regression analysis confirmed these associations. More frequent viewers were significantly less likely to eat breakfast (odds ratio (OR), 0.63; 95% confidence interval (CI), 0.58-0.68), and more likely to consume fast food (OR, 1.85; 95% CI, 1.69-2.02), high-caffeine drinks (OR, 1.43; 95% CI, 1.30-1.56), sugary drinks (OR, 1.54; 95% CI, 1.41-1.67), and late-night snacks (OR, 1.37; 95% CI, 1.25-1.51). Conclusions: Our findings suggest that frequent exposure to Mukbang and Cookbang content is linked to unhealthy dietary habits in adolescents. Educational programs may be necessary to mitigate the potential for these videos to negatively influence dietary choices.

친밀한 친구 관계를 맺고 소속감을 느끼는 것은 청소년의 심리·사회적 발달 및 적응에 긍정적인 영향을 미친다. 소속감 지향성은 소속감을 추구하는 동기로, 성장 지향성과 결핍감소 지향성으로 구분된다. 성장 지향성과 결핍감소 지향성은 심리적 적응 및 대인관계 특성에 서로 다른 영향을 주는 것으로 알려져 있다. 본 연구의 목적은 청소년의 소속감 지향성이 심리적 적응과 친구 네트워크에 미치는 효과를 알아보는 것이다. 이를 위해 한 중학교의 2학년 전체 학생을 대상으로 학기 초와 학기 말에 검사를 실시했다. 친구 네트워크는 네트워크 수신 중심성 분석을 통해 측정했다. 다층 회귀모형을 사용한 분석 결과는 첫째, 학기 초의 외로움과 스트레스에 대한 성장 지향성의 효과는 학기 초 친구 네트워크 중심성을 분석 모형에 함께 투입해도 유의했으나, 결핍감소 지향성의 효과는 유의하지 않았다. 둘째, 성장 지향성은 학기 말의 친구 네트워크 중심성을 유의하게 예측했다. 이러한 효과는 학기 초 친구 네트워크 중심성과 학기 말 심리적 적응 수준을 분석 모형에 함께 투입해도 유의했다. 셋째, 학기 말의 심리적 적응에 미치는 학기 말의 친구 네트워크 중심성의 효과는 학기 초 및 학기 말의 심리적 적응을 모형에 함께 투입해도 유의했다. 본 연구는 단기-종단적 설계를 통해 소속감 지향성이 청소년의 학기 초와 학기 말의 심리적 적응과 친구 네트워크 수준에 미치는 효과를 경험적으로 밝혔다는 점에서 의의가 있다. 끝으로, 본 연구의 한계점 및 후속 연구를 위한 제언을 논의했다.

The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16^th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

Purpose: The purpose of the study was to investigate health behavior changes in Korean adolescents before and during the COVID-19 pandemic. Methods: A descriptive cross-sectional design was employed. Data were obtained from the 15~16th (2019~2020) Korea Youth Risk Behavior Web-based Survey. Overall, the data of 112,251 students, 57,303 before the COVID pandemic and 54,948 during the pandemic, were included. The data were analyzed using rao-scott 𝝌²-test, t-test, ANCOVA and logistic regression analysis. Results: While sitting time for study decreased, sitting time for leisure increased in the 2020 group compared to the 2019 group. The 2020 group was more likely to skip breakfast and have a higher BMI than the 2019 group. The 2020 group was less likely to consume fruit and engage in moderate and vigorous physical activities than the 2019 group. The 2020 group was less likely to engage in CC, EC, and HTP current smoking and be exposed to secondhand smoke at home, school, and public places than the 2019 group. The 2020 group was more likely to be satisfied with sleep, but less likely to experience stress, depression, suicidal ideation, suicidal plans, and suicidal attempts than the 2019 group. Conclusion: It is necessary to reduce sedentary time, encourage physical activities, manage smoking and drinking rates continuously, and establish a network system to prevent psychological loneliness and isolation for adolescents, which requires participation of experts from the community as a whole.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.

This study examined dietary habits and mental health according to generalized anxiety disorders (GAD) and caffeine consumption in adolescents. The data were collected from the 18^th Korea Youth Risk Behavior Survey with a sample of 51,850 students. The proportion of students in the GAD High-Risk·Caffeine consumption group (GHRCC) who consumed sweet drinks (p< .001), fast food (p< .001), and midnight meals (p< .001) every day was 15.6, 21.9, and 22.4%, respectively. These proportions were higher than those of students who consumed sweet drinks, fast food, and midnight meals 1-2 times a week, 3-4 times a week, or not at all. In addition, the proportions of GHRCC among students who responded "yes" to experiencing sadness and despair (p< .001), suicidal thoughts (p< .001), suicide plans (p< .001), suicide attempts (p< .001), and loneliness (p< .001) were higher than students who responded "no." The GAD High-Risk group (GHR) had higher odds with the consumption of midnight meals (OR: 2.51, 95% CI: 2.10-2.99), caffeine consumption (OR: 2.46, 95% CI: 2.21-2.74), and fast food (OR: 2.11, 95% CI: 1.75-2.55) than GAD Low-Risk group. Based on the above results, the risk of GHR was higher among students who consumed midnight meals, caffeine, and fast food daily than those who did not.

본 연구의 목적은 중도입국청소년의 한국사회 입국 전 후 삶의 맥락에 대하여 깊이 있게 알아보는 것이었다. 이때 본 연구의 참여자는 중도입국청소년의 가장 많은 수를 차지하는 조선족 청소년이었다. 이들은 중국에서 아주 이른 시기에 친모와 이별을 경험했고, 양쪽 부모의 양육 부재 속에 친인척 등에 의해 대리양육 되기도 했다. 이때 심리적인 외로움과 공허함은 삶을 무기력하게 만들기에 충분했고, 반신반의 기대를 가지고 택한 한국행은 그들의 삶에 커다란 도전이 되었다. 한국에 온 후에는 안 좋은 행동들을 하면서 스스로의 안전을 저해하기도 했고, 무기력한 시간들을 보내기도 했다. 또 친부모와 다시 새롭게 구축해야 하는 가족관계, 계부모와 이복 혹은 동복동생과의 관계로 인해 힘듦을 경험하기도 했다. 하지만 그들의 내면에는 스스로에 대한 긍정성과 앞으로 나아지지 않을까라는 기대감이 존재했고, 이들을 지원하는 가족 및 사회적 지지체계가 존재함으로 인해 발전 가능성을 가질 수 있었다. 결과 분석에는 조선족 청소년 7명의 구술 자료가 사용되었고, 이를 토대로 관련 프로그램에 반영될 수 있는 실천적 제언을 하였다.
