BACKGROUND: Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus (HAV). The purpose of this study was to investigate the HAV vaccination status and related factors among college students. METHODS: The study subjects were 503 students conveniently sampled from C university located in one district of Jeollanamdo. General characteristics and HAV vaccination related factors were collected by a self-reported questionnaire in October 2013. Chi-square tests and multiple logistic regression analyses were used to evaluate related factors with HAV vaccination. RESULTS: Of the 503 subjects without a history of HAV infection, 65 subjects (12.9%) reported that they were vaccinated. In multiple analyses, subjects who have had health screening (adjusted odds ratio, aOR=2.44 and 95% confidence interval, 95% CI=1.26-4.73) and those who were aware of HAV infection (aOR=6.00, 95% CI=1.81-19.91) or who perceived the benefits of HAV vaccine (aOR=2.05, 95% CI=1.07-3.93) were more likely to be vaccinated than those not involved in these factors. With regard to intention for HAV vaccine, 314 subjects (71.9%) reported that they have the intention to be vaccinated against HAV. In multiple analyses, higher grade level, high monthly allowance, awareness of HAV vaccine, perceived susceptibility of HAV, perceived seriousness of HAV and perceived benefits of HAV vaccine were significantly associated with the intention for HAV vaccination. CONCLUSIONS: The vaccination rate for HAV was found to be low in our sample of college students. To reduce health risks related with HAV, prevention efforts should consider these results.

PURPOSE: The purpose of this descriptive study was to identify the impact of workplace bullying and LMX (Leader-Member Exchange) on turnover intention among nurses. METHODS: The participants were 364 nurses from the Seoul metropolitan area who were attending a continuing education program. A structured questionnaire was used for data collection and data were analyzed using the SPSS/Window program. Hierarchical multiple regression analysis was performed to verify the effect of variables on turnover intention. RESULTS: Higher workplace bullying was associated with higher turnover intention. Workplace bullying was negatively correlated with leader-member exchange. The most influential factors for turnover intention were LMX (beta=-7.22, p<.001), work load (beta=2.96, p=.003), and workplace bullying (beta=2.64, p=.009). These factors accounted for 28% of the variance in turnover intention. CONCLUSION: The study results indicate that there is need to develop strategies to prevent workplace bullying and cultivate a good relationship between nursing managers and nurses to lower nurses' turnover intention.

Objective: We aimed to assess the associations between problematic smartphone use, unhealthy behaviors, and mental health status among adolescents. Methods: The data for this cross-sectional study were obtained from the 13th Korea Youth Risk Behavior Survey (2017). From among the 62,276 adolescents who participated in this nationwide web-based survey, 54,603 (87.7%) who used smartphones were selected as the study population. Unhealthy behaviors included smoking, drinking, physical inactivity, skipping breakfast, and fast food consumption. For the examination of mental health status, we considered sleep disturbances, stress, depressive symptoms, suicidal ideation, and suicide attempts. The associations between problematic smartphone use, unhealthy behaviors, and mental health were analyzed using multiple logistic regression analyses. Results: More than four hours of use on weekdays (31.3%) and weekends (61.3%) and the use of smartphones for communication (46.9%) were associated with unhealthy behaviors and mental health problems. Furthermore, adolescents who experienced conflicts with family (22.3%) and friends (25.8%) and academic problems (3.4%) were likely to have health problems. Conclusion The results suggest that problematic smartphone use may disrupt adolescents’ health. Therefore, there is a need for prevention programs for problematic smartphone use at home and at school to improve adolescents’ health.

Objective: We aimed to determine the status of depression and its related factors among adult Koreans during the coronavirus disease 2019 (COVID-19) outbreak. Methods: We used data from the 2020 Korea Community Health Survey (KCHS). We assessed depressive feelings and symptoms using the Patient Health Questionnaire-9 (PHQ-9 ≥10). In addition, we assessed general and COVID-19–related characteristics, including isolation due to and concerns about COVID-19. We analyzed the data using chi-square tests and multiple logistic regression analyses. Results: The rates of depressive feelings and symptoms were 5.9% and 2.9%, respectively. Of the adult respondents, 68.5% were concerned about COVID-19, while 75.9% were concerned about economic harm due to COVID-19. The adjusted odds ratios for depressive symptoms assessed using the PHQ-9 were significantly high among women responders, adults aged 19–44 years, low-income households, those who experienced COVID-19–related symptoms, and those concerned about death due to COVID-19 and economic harm due to COVID-19. Similar results were obtained for depressive feeling. Conclusion Concerns related to COVID-19 infection are related to depression. This suggests that COVID-19 significantly affects mental health. Therefore, during public health crises, such as new communicable diseases, mental health and the incidence of the infectious disease require assessment and monitoring.

BACKGROUND: The risk for a hand injury was increased according to industrial structure and lifestyle change. This study investigated the post traumatic stress (PTS) and related factors in some hand replantation patients. METHODS: Total 150 hand replantation patients in one hospital were selected using convenience sampling methods. General characteristics of patients, characteristics of injured hand, self-esteem and PTS were collected using self-reported questionnaires. And clinical characteristics of injured hand were obtained from a review of medical records. Descriptive analysis, t-test, ANOVA and multiple regression analysis were performed to determine the associated factors with the score of PTS. RESULTS: Among 150 patients, 80% were male and 94% had a job. The mean score of PTS was 22.2±16.9. In simple analysis, PTS score were associated with smoking status, injury day of the week, pain score and self-esteem. Finally, the subjects who injured in weekdays had significantly higher PTS score compared to subjects who injured in weekend (β=0.185, P=0.021) and pain score was positively associated with PTS score (β=0.181, P=0.027) in multiple regression analysis. CONCLUSIONS: Injury day of the week and pain score were associated with PTS score in some hand replantation patients. Considering these results will help to management and improve quality of life of hand replantation patients.

Short (< or = 6 hr) and long (> or = 9 hr) sleep durations are both associated with risk factors for cardiovascular diseases and diabetes, depression, learning problems, accidents and excess mortality. However, little is known about factors associated with sleep duration in Korean adults. This study examined sleep patterns in Korean adults and identified factors associated with short and long sleep durations. This study analyzed cross-sectional data collected from 4,411 Korean adults aged 19 yr and older who participated in a community health survey conducted in Gwangju, Korea. Multinomial logistic regression analysis was used to identify associations between socio-demographic and health-related factors and short or long sleep durations. Of the population, 37.2% and 4.0% reported short and long sleep, respectively. Short sleep was associated with older age, lower levels of income, night or shift work, heavy smoking, and depression or anxiety; long sleep was associated with younger age, being divorced or widowed, heavy smoking, underweight, depression or anxiety, and poorer self-reported health. In conclusion, a relatively high prevalence of short sleep duration is identified in this population of Korean adults. Factors associated with short or long sleep may act as potential confounders of the relationship between sleep duration and health outcomes.

Background: This study was conducted to investigate factors related to unmet medical needs of medical care in adult diabetes patients and to suggest factors related to unmet medical in Korea. Methods: This study used data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2014–2017. The subjects of the study were conducted on patients with unmet medical needs experience among the patients and analyzed using the IBM SPSS ver. 25.0 program (IBM Corp., Armonk, NY, USA). Results: Overall, 10.9% of patients had unmet medical needs. Being female, less educated, and lower medical aid were related to unmet medical needs. And subjects with poor subjective health and higher stress level were more likely to report unmet medical needs. Conclusion Although comprehensive health insurance coverage, 10.9% of people with diabetes experienced unmet healthcare needs. The results of this study suggest that socioeconomic factors such as low education and medical aid were associated with unmet medical needs.

Objectives: This study examined the current status of depression and related factors among children using community child center. Methods: A cross-sectional study selected children in grades 4-6 who used the Gwangju and Jeollanamdo community child center (n=224) using a convenience sampling method. General characteristics, family characteristics, children's emotional characteristics, children's school life environment and depression status were assessed using a self-reported questionnaire. Results: The average score of depression among children using community child center was 15.31±7.70 out of a total of 27. Fifty-eight (25.9%) children had depression above 22 points. Variables related to children's depression were shown as grade, subjective economic level awareness, after-school activities excluding local children's centers, presence of family members after school, and family structure. Conclusions The depression prevalence of children using community child center was higher. Policy support such as children's psychological support programs would be needed to reduce children's depression, and community child centers are expected to be effective in reducing children's depression if continuous child psychological support services are developed for children's mental health.
