Objectives: Smartphone overdependence (SOD) and anxiety are major concerns in adolescent mental health; however, few studies have examined their bidirectional relationship. This study aimed to examine reciprocal associations between SOD and anxiety among adolescents. Methods: A secondary analysis was conducted with data from 50,975 adolescents in the 19th Korea Youth Risk Behavior Survey. SOD was measured using the SOD scale, and anxiety was assessed using the generalized anxiety disorder 7-item scale. Multivariable logistic regression analyses were conducted to examine reciprocal associations, adjusting for sociodemographic factors, perceived stress, loneliness, and depressive symptoms. Results: Moderate to severe anxiety was found in 12.6% of participants, and 3.3% were classifiedas being at high risk for SOD. In adjusted models, the model with anxiety as the outcome demonstrated higher predictive performance (concordance rate, 86.5%) than the model with SOD as the outcome (77.3%). Adolescents at high risk for SOD had higher odds of reportinganxiety, and those with severe anxiety had higher odds of being classified as at high risk for SOD. Stress, loneliness, and smartphone use time were also identified as significant predictors. Conclusion SOD and anxiety were strongly associated with each other among adolescents.Integrated approaches addressing both digital behavior and mental health may help informstrategies to reduce psychological distress. Public health strategies may benefit fromconsidering both aspects when screening for problematic smartphone use and anxiety.

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.
