Objective: Suicide is a leading cause of death among adolescents, and despite the need to distinguish between suicidal consideration and suicide attempts, research focused on suicide attempts remains insufficient. Therefore, this study aims to investigate the influence of self-perceived weight on suicide attempts. Methods: This study utilized data from the Korea Youth Risk Behavior Web-based Survey for its analysis from 2005 to 2023, including a total of 1,156,728 participants. This study utilized various analytical methods to examine the influence of self-perceived weight on suicide attempts. We estimated weighted prevalence and used linear regression to assess temporal trend β coefficients and their differences (βdiff) with 95% confidence intervals (CIs), and survey-weighted logistic regression to estimate weighted odds ratios (wORs) and 95% CIs for the association between self-perceived weight and suicide attempts. Results: A comparison of suicide attempts based on self-perceived weight suggested that individuals who perceived themselves as overweight (weighted prevalence, 3.97% [95% CI, 3.89 to 4.04]) had the highest rate of suicide attempts, followed by those who perceived themselves as underweight (3.36% [95% CI, 3.28 to 3.44]), while those who perceived themselves as having a normal weight (3.20% [95% CI, 3.14 to 3.27]) had the lowest rate. Additionally, females (underweight: 4.47% [95% CI, 4.32 to 4.62]; normal weight: 3.91% [95% CI, 3.81 to 4.01]; overweight: 5.23% [5.11 to 5.35]) experienced more suicide attempts than males (underweight: 2.73% [95% CI, 2.65 to 2.82]; normal weight: 2.43% [95% CI, 2.35 to 2.51]; overweight: 2.60% [95% CI, 2.52 to 2.69]). Conclusion Findings from the present study suggest that self-perceived weight was associated with suicide attempts and interaction analyses indicated a potential sex-based difference in the impact of body image distortion. Therefore, this study suggests the introduction of programs and campaigns aimed at correcting distorted self-perceived weight.

OBJECTIVE: Despite the global decrease in influenza infections during the coronavirus disease 2019 (COVID-19) pandemic, seasonal influenza remains a significant health issue. South Korea, known for its robust pandemic response and high influenza vaccination rates, offers a unique context for examining changes in vaccination trends during the pandemic. Using nationally representative data, we aimed to understand the impact of the pandemic on influenza vaccination behavior over a 12-year period and to identify vulnerable groups. METHODS: We analyzed influenza vaccination rates in South Korea between 2011-2022, focusing on pandemic-related impacts. The data of 2,426,139 adults (≥ 19 years) from the Korea Community Health Survey were used to assess demographic and sociological factors influencing vaccination behaviors. RESULTS: We observed an increase in influenza vaccination rates during the pre-COVID-19 period from 2011-2013 (weighted prevalence: 46.68% [95% confidence interval ( CI): 46.55-46.82]) to 2017-2019 (weighted prevalence: 52.50% [95% CI: 52.38-52.63]). However, a significant decline was observed in 2022, the late-COVID-19 pandemic period (weighted prevalence: 55.78% [95% CI: 55.56-56.01]), compared with the mid-pandemic period in 2021 (weighted prevalence: 59.12% [95% CI: 58.91-59.32]), particularly among populations traditionally prioritized for influenza vaccination, including older adults (≥ 65 years) and patients with chronic diseases and low educational and income levels. CONCLUSION The influenza vaccination rate in South Korea was significantly affected by the COVID-19 pandemic, showing a notable decrease among vulnerable demographic groups. This suggests the need for targeted public health strategies to address vaccine hesitancy and improve vaccination rates, particularly among high-risk populations.

BACKGROUND/OBJECTIVES: This study investigated the relationship between adolescent food-related lifestyles and food-related media use and eating behavior in Korea. SUBJECTS/METHODS: Participants were 392 Korean adolescents, ranging in age from 12 to 18, recruited via convenience sampling. They completed a self-report questionnaire survey consisting of questions about food-related lifestyle, food-related media use, food consumption behavior, food literacy, and nutrition quotient. Data analysis was conducted using SPSS 29.0. (IBM Co., Armonk, NY, USA). RESULTS: The factor analysis of food-related lifestyles identified four factors. Based on the cluster analysis results, participants were classified into three clusters reflecting different levels of interest: high interest in food, moderate interest in food, and low interest in food. The analysis revealed significant differences between groups in food-related liestyle factors (P < 0.05). Notably, the high-interest group demonstrated proactive engagement with food-related content, a willingness to explore diverse culinary experiences, and a conscientious consideration of nutritional labeling during food purchases. In contrast, the low-interest group reported tendencies toward overeating or succumbing to stimulating food consumption post-exposure to food-related content, coupled with a disregard for nutritional labeling when making food choices. A stronger inclination toward a food-related lifestyle was positively correlated with higher levels of food literacy and nutrition quotient. CONCLUSION This study proposes that the implementation of a nutrition education program using media could effectively promote a healthy diet among adolescents with a high level of interest in their dietary habits. For adolescents with low interest in their dietary habits, it suggests that introducing an education program with a primary focus on enhancing food literacy could be beneficial in fostering a healthy diet. Our research findings provide insight for the development of tailored nutritional education programs and establishment of effective nutrition policies.

Purpose: The purpose of this study was to identify individual and occupational factors influencing burnout, secondary traumatic stress, and compassion satisfaction in military officers who experienced supporting civilians in responding to COVID-19. Methods: This descriptive study was conducted on 140 special forces’ military officers who experienced responding to disasters within 3 months. Data were collected through an online survey from September to November 2021. Results: The mean scores for burnout, secondary traumatic stress, and compassion satisfaction were 21.67±6.03, 20.54±8.21, and 39.72±8.12 out of 50, respectively. The significant factors that influenced burnout and secondary traumatic stress were ‘higher passive stress copying styles’ (B=0.17, p<.001; B=0.31, p=<.001, respectively) and ‘lower social support (B=-0.11, p=.031; B=-0.10, p=.001, respectively). The compassion satisfaction was more significantly associated with ‘higher self-efficacy’ (B=0.37, p=<.001), ‘higher active stress copying styles’ (B=0.19, p=.006), and ‘education responding to disasters’ (B=2.04, p=.029). Conclusion The results suggest that the strategies to increase social support, self-efficacy, and active stress coping styles should be considered in developing educational programs for military officers responding to disasters to minimize burnout, secondary traumatic stress and to improve compassion satisfaction.

Objective: PD-1 inhibitors have demonstrated improved health outcomes in cancer patients. PD-1 inhibitors are well-tolerated and associated with immune-related adverse events. The objectives of this study are to analyze use patterns of PD-1 inhibitors in patients with cancer and to investigate the incidence of thyroid-related adverse reactions in patients treated with PD-1 inhibitors. Methods: The study included patients who had been administered PD-1 inhibitors (either nivolumab or pembrolizumab) at the Samsung Medical Center between October 1, 2016 and June 30, 2017. Data was collected from electronic medical records and tested using Mann-Whitney tests and Chi-Square tests for statistical significance. Associations between PD-1 inhibitors and incidence of adverse events were tested using Cox regression for age, gender, BMI, ECOG PS and medication. Results: Two hundred fifteen patients were identified as eligible for analyses. Thyroid-related adverse events occurred in 20% of patients (n=43). Thyroid function tests (TFTs) was performed in 109 patients (50.7%). Positive results of PD-L1 testing were found in 53.2% of the 94 patients who had the test. Approved doses of nivolumab (3 m/kg) and pembrolizumab (200 mg) were administered in 70.4% and 53% of patients, respectively. The analysis of risk factor of thyroid-related adverse reaction did not show statistically significant differences (Cox regression). Conclusion Thyroid-related adverse events are common in patients treated with PD-1 inhibitors and hypothyroidism is the most frequent adverse reaction. Routine TFTs monitoring is strongly recommended to evaluate thyroid function in real-world clinical practice.
