Purpose The purpose of this study was to investigate factors related to the length of stay of patients with COVID-19 in one region.
Methods: The study included 729 elderly patients with COVID-19 who were hospitalized. Data were collected through a survey of patients with epidemiological investigation in the Integrated Disease and Health Management System by public health center staff from April 2020 to January 2022. The collected data were analyzed using the t-test, ANOVA, Pearson's correlation coefficient, and Hierarchical regression analysis.
Results: In this study, the average length of hospital stay was approximately 10.3 days, and the hierarchical regression analysis results showed that as age (β = .28, p < .001) increased, the length of hospital stay became shorter when diagnosed in the delta mutation period (β = -.15, p = .001) compared to before the delta mutation period, and when vaccination was administered three or more times (β = -.18, p = .003). The explanatory power of the final model was approximately 18% (Adjusted R2=.16, F = 13.23, p < .001).
Conclusion The results of this study emphasize the importance of early detection and preemptive treatment of COVID-19 in the older adults and other high-risk groups and the need to reduce the severity by implementing additional vaccinations.
Purpose This study was to determine how attitude, subjective norm, and perceived behavioral control (PBC) were related to parents' intentions to vaccinate their sons in elementary school against human papillomavirus (HPV), applying the updated theory of planned behavior. Two hypotheses were examined: PBC would moderate the relationship of attitude to intention and subjective norm to intention, respectively. Methods This was a cross-sectional study with 231 participants recruited in November, 2018. Inclusion criteria for the participants were parents with 5th-6th grade boys in elementary schools. The moderation effects of the hypotheses were analyzed using the PROCESS macro for SPSS. Results PBC significantly moderated the relationship of attitude to intention on HPV vaccination. The simple effect of attitude to intention was significant under three different levels of the PBC (low, moderate, and high), but the magnitudes of the relationships were not homogeneous. The magnitude of the relationship between attitude and intention was the lowest for the parents with the low level of the PBC. In the relationship of subjective norm to intention on HPV vaccination, the moderating effect of the PBC was not supported.
Subjective norm and PBC directly predicted the intention on HPV vaccination. Conclusion In order to promote the parents' intentions to vaccinate their sons in elementary school against HPV, we need a program that can improve parents’ attitude, subjective norm, and PBC, requiring special attention to the parents with the low PBC.

Purpose Influenza immunization among health personnel is of particular importance given their elevated risk of influenza infection, role in transmission and influence on patients' immunization status. The purpose of this study is to identify factors associated with the influenza vaccination intention among health personnel based on the theory of planned behavior. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 131 health personnel in five general hospitals in two cities in South Korea. The data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with the SPSS 26.0 program. Results There were statistically significant differences in influenza vaccination intention according to the high-risk group in the family, occupation, length of employment, and influenza vaccination status within a year. The influenza vaccination intention of these health personnel showed significant positive correlations with attitude, subjective norms, and perceived behavioral control towards influenza vaccination. Multiple regression analysis for influenza vaccination intention revealed that the significant predictors were attitude, subjective norms, influenza vaccination within a year and physician in occupation. These factors explained 41.4% of the variance. Conclusion The results suggest a need to strengthen attitude and subjective norms. The findings also suggest that their characteristics through influenza vaccination status within a year and occupation should be considered for tailored interventions related to the intention. Furthermore, it is necessary to develop programs strengthening attitude and subjective norms to enhance influenza vaccination intention among health personnel.

PURPOSE The aim of this study was to identify the level of Human papillomavirus (HPV) knowledge, intention of HPV vaccination, and barriers on HPV vaccination among male undergraduate students of Health department and Non-health department. METHODS A total of 149 male undergraduate students responded to self-administered questionnaires about their HPV knowledge, HPV vaccination intention, and their barriers on HPV vaccination. ANOVA, t-test and χ2 test (Fisher's exact test) were used for data analysis. RESULTS Mean score of HPV knowledge was 3.39±3.05, and there was significant difference between Health department (4.15±3.08) and Non-health department (2.58±2.82) in HPV knowledge (t=3.241, p=.001). There was no significant difference in HPV vaccination acceptance between the two groups. The barriers on HPV vaccination were 'lack of information about HPV vaccine efficacy' and 'lack of information about HPV vaccination time and strategy', and there were significant differences in barriers on HPV vaccination between the two groups. CONCLUSION The knowledge on HPV was low, and HPV vaccination was hindered due to lack of information about HPV vaccine despite their intention to obtain HPV vaccine. HPV education to promote HPV vaccination should be targeted among male students.

PURPOSE This study aimed to investigate the rate of and factors associated with influenza vaccination in Korean elderly people. METHODS For this retrospective cross-sectional study, we used data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008. A total of 1,516 men and women aged 65 or above were included. The data were analyzed using descriptive statistics and logistic regression. RESULTS The overall rate of influenza vaccination in 2008 was 73.6%. The vaccination rate was lower in women (73.2%) than in men (74.2%; p<.001). It was lower in the elderly aged 80 and above, those living in metropolitan areas, smokers, those who did not receive regular health screening, those who had no history of hospitalization within one year, and those who had liver diseases than in the other groups. The rate of vaccination was higher in those with cancer. Logistic regression analysis revealed that for both men and women, the significant correlates associated with vaccination were demographic factors, chronic disease and health behavior. CONCLUSION The influenza vaccination coverage needs to be improved. Efforts should be made to reach the elderly population with relatively low influenza vaccination rates and to increase awareness about the importance of vaccination at a personal and community level.

PURPOSE The purpose of this study was to investigate the influencing factors of influenza vaccination in the elderly participating in lifetime transitional health examination. METHODS This study was a secondary analysis of data collected from lifetime transitional health examination (for 66-year-old people) conducted by the National Health Insurance Corporation (NHIC) from January 1 to December 31, 2008. Questionnaires were received from NHIC to obtain information regarding gender, chronic diseases, health-related behaviors, and ADL. A total of 255,333 participants who responded all the questions in the questionnaire were included in the analysis. Collected data were analyzed by descriptive statistics, chi2 test, and multiple logistic regression. RESULTS The influenza vaccine coverage rate in 66-year-old people was 66.1%. The influenza vaccine coverage rate was higher in female elders and those with hypertension, diabetes, heart disease or past smoking, and lower in those with stroke, current smoking, drinking, no-exercise or ADL-dependency. CONCLUSION Strategies for improving the influenza vaccination coverage rate in the elderly are needed. The strategies should give priority to the elderly with current smoking, drinking, and no-exercise, and home visiting programs are needed for the elderly with stroke and ADL-dependency.
