Purpose: This study aimed to compare the factors influencing suicidal ideation among middle and high school students in South Korea. Methods: Data from the 18th Korea Youth Risk Behavior Web-based Survey conducted in 2022 (n=51,850) were analyzed using a logistic regression to calculate the odds ratios for suicidal ideation risk factors. Results: Among middle school students, smoking, drinking, and other delinquent behaviors had higher odds ratios compared to those of high school students. For high school students, depression, loneliness, anxiety, and other mental health issues showed greater odds ratios than in middle school students. The findings highlight developmental differences in suicidal ideation risk profiles between middle and high school students. Targeted prevention and intervention strategies tailored to each age group are recommended. Conclusion Despite the narrow age range, this study revealed distinct patterns of suicidal ideation risk factors among adolescents in their early and late teens. Schools and policymakers should consider these differences when designing suicide prevention programs.

Purpose: The purpose of this study was to develop eating traits scale for Korean adults and verify its validity and reliability. Methods: The initial items were developed based on the literature reviews. The first preliminary scale has consisted of 78 items and the second preliminary scale consisted of 50 items selected by 13 experts who were formed to evaluate the content validity. To review whether they could understand the questionnaires at their reading level, 27 sixth-grade elementary school students were asked to be involved in this study. The questionnaire was revised through the consultation of Korean language teachers, and the final preliminary scale was composed of 50 items. Data were collected from 329 adults aged 19 to 65 years to test validity and reliability of the scale The item analysis and exploratory factor analysis were applied. Results: Exploratory factor analysis showed 5 factors of 35 items. The factors (No. of items) were ‘Mood states (6)’, ‘Pursuit of health (6)’, ‘Stimulation of food (9)’, ‘Social situations (5)’, ‘Desire satisfaction (9)’. These 5 factors explained 55.04% of the total variance. Eating traits scale developed in this study was established construct validity. The reliability of the scale, Cronbach's alpha coefficient was .92 and the factor’s ranged from .77 to .87. Conclusions Eating traits scale developed in this study was verified by content validity, construct validity and reliability. It is expected to be useful measuring eating traits of Korean adults in clinical practice and research.

Objectives: This study investigated the association between living arrangements and health-related quality of life (HRQoL) in older people. Methods: A secondary analysis was conducted of 6,153 participants (aged ≥60 years) from the seventh Korean National Health and Nutrition Examination Survey (2016 to 2018). HRQoL was measured using the 3-level version of the EuroQol 5-dimensional questionnaire. The chi-square test, t-test, and multiple regression were used, applying sampling weights for the analysis. Results: The proportion of respondents living alone was 18.0%, with a higher prevalence among women and older age groups (p<0.001). The overall HRQoL was lower in groups living alone than in groups living with others (p<0.001). Older people living alone showed higher impairments in all dimensions of the 3-level version of the European Quality of Life 5-Dimensional Questionnaire (EQ-5D-3L) than those living with others, including mobility (p<0.001), self-care (p<0.001), usual activities (p<0.001), pain/discomfort (p<0.001), and depression/anxiety (p<0.001). Problems with mobility were most prevalent (42.8%), followed by pain/ discomfort (41.9%) in respondents living alone. Living alone was significantly associated with a lower HRQoL index score (b=–0.048, p<0.001) after adjusting for age, gender, education, exercise, perceived stress, and perceived health status. Conclusion Living alone was negatively associated with HRQoL. Based on this study, future care planning for older people should consider their living arrangements. The need to strengthen and expand care programs targeting those living alone should also be addressed.

OBJECTIVES: We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea. METHODS: In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022. RESULTS: In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%. CONCLUSIONS The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.
