Background As of January 2022, the number of people infected with COVID-19 worldwide has exceeded 350 million. As the COVID-19 pandemic continues, people are affected in a wide range of areas of life, which in turn causes numerous psychological problems. Depression is a serious problem for people who have suffered from COVID-19. Depression can worsen COVID-19 precautionary behavior compliance or the health behavior itself. In addition, these depressive symptoms may have different characteristics depending on the individual’s gender. Objective The aim of this study was to determine whether depression is a factor that may affect COVID-19 fear, precautionary behavior compliance, and health behavior, and how these characteristic trends differ by gender. Methods This was a secondary analysis of data from the 2020 Korea Community Health Survey (KCHS), a national cross-sectional survey conducted with complex sampling analysis. In 2020, the KCHS included COVID-19–related questions. For this study, we used the KCHS data from both the COVID-19–related questions and the Patient Health Questionnaire-9 scale. After weighting the data according to the KCHS guidelines, we calculated the distribution of men and women according to depression level. The data were collected using multiple-choice questions related to precautionary behavior compliance, COVID-19–related fears, and health behavior changes. Results Of the 204,787 participants, those who were clinically depressed had a greater tendency to not comply with precautionary behaviors. Regarding COVID-19, “fear” showed a decreasing trend in both men (adjusted odds ratio [AOR] 0.72, 95% CI 0.61-0.83) and women (AOR 0.74, 95% CI 0.63-0.86) with clinically relevant depression. Moreover, for both men and women, health behaviors deteriorated as depression intensified; the AOR for sleep duration changes was 2.28 (95% CI 2.00-2.59) in men and was 2.15 (95% CI 1.96-2.36) in women. Notably, the responses of clinically depressed women revealed a doubled increase in both their drinking (AOR 2.25, 95% CI 1.88-2.70) and smoking (AOR 2.71, 95% CI 1.95-3.77) habits compared with those of nondepressed women. Conclusions Both men and women with more severe depression were more likely to violate precautionary health behaviors as their depression worsened. Health behaviors also deteriorated for both genders, but women tended to show a greater change. Therefore, additional studies and interventions for vulnerable groups such as severely depressed people are needed. More research is also necessary to develop interventions based on statistical comparisons of men and women.

Background Despite the increased demand for nurses worldwide, discussion of nurses’ duty to care is lacking. This study aimed to examine nurses’ duty to care during the coronavirus disease 2019 (COVID-19) pandemic and to identify the influencing factors. Methods This was a cross-sectional descriptive research study that used a structured online questionnaire. Registered Korean nurses answered a demographic questionnaire and the Nash Duty to Care Scale. Results Age and employment at tertiary hospitals increased nurses’ duty to care. Male sex, a highly educated status, and employment at tertiary hospitals increased the perceived risk. Male sex and employment at tertiary or general hospitals increased confidence in the employer, while a high level of education and a longer total clinical career decreased the same. Age and a higher monthly wage increased perceived obligation. Age, lack of religious beliefs, and clinical experience of 3–7 years increased professional preparedness. Conclusion Without enough nursing manpower, the disaster response system could prove to be inefficient. Considering that adequate nurse staffing is essential in disaster management, it is crucial to ensure that nurses have a will to provide care in the case of disaster. In the future, a more active discussion on nurses’ duty to care and additional research on factors that may hinder and facilitate the same are needed.

This study aimed to confirm the relationships between part-time work experience, mental health, and suicidal behavior in adolescents. The impact of part-time work in this population is a controversial topic, perhaps because of the sociocultural background-related inconsistencies in previous results. In this cross-sectional study, which involved a secondary analysis of data from the 11th–13th Korea Youth Risk Behavior Web-Based Surveys, conducted among 800 middle and high schools by the Korean government, we used propensity score matching analysis to minimize the impact of individual backgrounds on the findings concerning the relationships in question. Overall, part-time experience was significantly related to mental health problems and suicidal behavior even after eliminating background differences. Adolescents with part-time work experience had higher overall stress levels (odds ratio = 1.148; 95% confidence interval = 1.094, 1.205) than those without such experience, and more suicidal thoughts (odds ratio = 1.355; 95% confidence interval = 1.266, 1.450), suicide planning (odds ratio = 1.717; 95% confidence interval = 1.527, 1.929), and suicide attempts (odds ratio = 1.852; 95% confidence interval = 1.595, 2.151). Thus, it is important to pay increased attention to mental health and suicide-related issues in South Korean adolescents with part-time jobs.

BACKGROUND Metabolic syndrome and obesity, known as major risk factors for chronic diseases, are closely related. This has led to two new concepts—“metabolically healthy obesity” (MHO) and “metabolically unhealthy obesity” (MUO)—with a high risk of transition from MHO to MUO. MHO has a lower likelihood of progressing to secondary chronic diseases compared with MUO, highlighting the importance of maintaining a metabolic, healthy status and prolonging this state. OBJECTIVE To identify the characteristics of individuals transition from MHO to MUO and to identify factors influencing the change. METHODS Data from the National Health Insurance Service in Korea was used. We collected data from individuals diagnosed with MHO during health screenings in 2009 and 2010, and those who were still identified with obesity four years later. We examined sociodemographic characteristics, physical examinations, blood test results, and lifestyle behaviors. Factors related to the transition to MUO were determined using logistic regression analysis by adjusting sociodemographic and physical characteristics. RESULTS We analyzed 1,564,467 individuals. There were statistically significant differences in all sociodemographic, physical, metabolic, and health behavior factors between subjects who transitioned from MHO to MUO and those who did not. Among the male population, the transition to MUO exhibited a positive association with and smoking and alcohol consumption, and a negative association with physical activity. Among females, alcohol consumption also showed a negative correlation. Regardless of age, regular exercise was negatively associated with the transition to MUO for all individuals. Except for older adults, participants of all age groups showed a positive correlation with smoking and alcohol consumption. CONCLUSIONS Considering the stronger influence of health behaviors on the transition to MUO in males and individuals under 65 years of age, it is essential to develop and implement interventions that consider gender and age to delay and prevent the onset of MUO. Furthermore, as physical activity significantly impacts reducing the transition to MUO and is an effective antidote intervention for obesity itself, there is a need to develop interventions that enable individuals to practically engage in regular exercise, regardless of age and gender.
