Abstract
OBJECTIVES
This study explored the association between dietary and suicidal behaviors of Korean adolescents and investigated differences in this association in children of immigrant parents.
METHODS
The sample (n=368,138) was collected from the Korea Youth Risk Behavior Survey from 2015 to 2020. Participants who agreed to provide family information (n=313,689) were classified according to their parents’ nationality. The study variables were 11 self-reported dietary behaviors, and their composite dietary behaviors (i.e., nutrient deprivation and unhealthy food consumption) that resulted from principal component analysis. The association between study variables and suicide-related outcomes (i.e., suicidal ideation, suicide planning, and suicide attempts) was analyzed by multiple logistic regression with adjustment for covariates. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated.
RESULTS
Participants who skipped key meals and foods were more likely to have attemped suicide (aOR [95% CI]: skipping breakfast ≥5 days/wk, 1.28 [1.21 to 1.35]; consuming fruits <1 times/wk: 1.42 [1.32 to 1.52]; consuming vegetables <1 times/wk: 1.72 [1.53 to 1.93]; consuming milk <3 times/wk: 1.07 [0.99 to 1.16]). The associations were prominent in third culture kids (TCKs) (aOR [95% CI]: 2.23 [1.61 to 3.09]; 2.32 [1.61 to 3.35]; 2.63 [1.50 to 4.60]; 1.69 [1.09 to 2.63], respectively). Participants who consumed unhealthy foods (fast food, caffeinated and sugary drinks) more frequently were more likely to have attempted suicide (aOR, 1.55; 95% CI, 1.38 to 1.73). This association was also more prominent in TCKs (aOR, 2.08; 95% CI, 1.08 to 4.01).
CONCLUSIONS
Our findings indicate a positive association between unfavorable dietary behaviors and outcomes related to suicide, and this association appears to be notable in adolescents with immigrant parents.
Summary
Korean summary
• 한국 청소년의 식이 행동과 자살 행동 사이의 연관성과 한국인 부모와 이민자 부모 자녀에서 위의 연관성 차이를 조사하였다. • 청소년의 결식 빈도 증가, 과일, 야채, 우유 섭취 감소는 자살 행동과 유의한 연관성이 있었으며 이민자 부모를 둔 청소년에서 연관성의 크기가 더 컸다. • 패스트푸드, 카페인, 가당 음료, 인스턴트 음식을 더 자주 섭취하는 청소년은 자살을 시도할 가능성이 더 높았으며 이민자 부모를 둔 청소년에서 더 큰 연관성을 보였다.
Key Message
The study found positive associations between undesirable dietary behaviors (e.g., skipping breakfast, increased consumption of fast food or instant food product) and outcomes related to suicide (i.e., suicide ideation, planning, and attempt) in Korean adolescents, and these associations appear to be prominent in adolescents with immigrant parents than those with Korean parents.

Abstract
OBJECTIVES
The aim of this study was to explore factors affecting attitudes toward coronavirus disease 2019 (COVID-19) vaccination, including socio-demographic characteristics and mental health status during the pandemic.
METHODS
This study analyzed responses from 1,768 participants who were originally included in a community cohort study and responded to 3 online surveys related to COVID-19 (March 2020 to March 2021). The k-means method was used to cluster trust in and intention to receive COVID-19 vaccination. Baseline (2013-2018) socio-demographic characteristics, physical health status, and depressive symptoms were analyzed as exposure variables, and current mental health status was included in the analyses.
RESULTS
Almost half of all participants were classified into the moderate trust and high intention cluster (n=838, 47.4%); those with high trust and high intention accounted only for 16.9%. They tended to be older, had high-income levels, and engaged in regular physical activity at baseline (p<0.05), and their sleep quality and psychological resilience were relatively high compared to other groups.
CONCLUSIONS
Our results suggest that more efforts are required to enhance the perceived need for and trust in COVID-19 vaccination.

Key Message
In this community-based study including 1,768 participants who responded online survey related to COVID-19, we investigate the relationship between mental health during the pandemic and attitude toward COVID-19 vaccine (trust and intention). Each of the mental symptoms, including depression, anxiety, and loneliness, was significantly associated with higher intention to COVID-19 vaccine. Our results suggest that more efforts are required to enhance the perceived need for and trust in COVID-19 vaccination.

Abstract
OBJECTIVES
Identifying determinants of prevention behaviours during the emergence of a new infectious disease is important. We investigated the associations between information-seeking and prevention behaviours during the coronavirus disease 2019 (COVID-19) pandemic and mediating effects of psychiatric factors.
METHODS
In total, 1,970 participants from the Cardiovascular and Metabolic Etiology Research Center cohort participated in an online survey 55 days after the first COVID-19 case in Korea was diagnosed. Time spent seeking information related to COVID-19; information sources; psychiatric factors, including anxiety, depression, post-traumatic stress symptoms (PTSS), and the fear of COVID-19; and prevention behaviours were examined. The mediating effect of psychiatric factors was estimated using mediation analysis.
RESULTS
Time spent seeking information and information sources affected several behavioural responses. In men, anxiety mediated associations between information-seeking and prevention behaviours, including purchasing sanitary supplies (effect size [ES], 0.038; 95% confidence interval [CI], 0.002 to 0.095) and hoarding (ES, 0.029; 95% CI, 0.002 to 0.068). The fear of COVID-19 also mediated associations between information-seeking and prevention behaviours including refraining from going out (men: ES, 0.034; 95% CI, 0.009 to 0.068; women: ES, 0.052; 95% CI, 0.030 to 0.080), wearing face masks (men: ES, 0.085; 95% CI, 0.031 to 0.184), avoiding public transportation (men: ES, 0.020; 95% CI, 0.000 to 0.044; women: ES, 0.031; 95% CI, 0.015 to 0.051), hoarding (women: ES, 0.051; 95% CI, 0.029 to 0.792), and trying alternative remedies (men: ES, 0.024; 95% CI, 0.004 to 0.053). Depressive symptoms and PTSS did not have any mediating effects.
CONCLUSIONS
While the availability of information related to COVID-19 can help prevent infections, it can also promote anxiety and fear, leading to negative behaviours such as hoarding and trying unverified alternative treatments.
Summary
Korean summary
-본 연구는 한국인에서 코로나-19 관련 정보탐색이 예방 행동과 상관관계가 있는지를 확인하고 불안, 공포, 우울을 비롯한 심리 상태가 이 상관관계를 매개하는 메커니즘으로 작용하는지를 확인하고자 하였다. - 본 코호트 연구에서 정보 탐색 시간이 길어질수록 예방 행동을 취하는 빈도가 증가하였으며 불안 및 코로나-19에 대한 공포가 이 둘 사이의 상관관계를 일부 매개하였다. - 정보탐색이 증가할수록 외출 자제, 마스크 착용, 대중교통 이용 자제와 같은 권장되는 예방 행동을 취할 가능성도 증가하였지만 사재기를 하거나 검증되지 않은 대체요법에 의지하는 등 권장되지 않는 예방 행동을 취할 가능성 또한 같이 증가하였다.
Key Message
In this study, we tried to test the association between information-seeking behavior and preventive measures during COVID-19 pandemic. We also tried to understand whether psychologic factors such as anxiety, fear against COVID-19 and depression mediate the association. We found that time used for searching COVID-19-related information is positively associated with preventive behaviors, and that anxiety and fear mediate the association. Information seeking increased the probability of utilizing recommended prevention strategy such as wearing facial masks and refraining from going out, but also promoted prevention behavior not recommended by government officials such as hoarding and trying alternative remedies.
