Abstract	This study explores the impact of the coronavirus disease 2019 (COVID-19) pandemic on outpatient visits for all-cause and chronic diseases in 2020. We extracted the data of patients who visited medical institutions over the past five years (2016–2020) from nationwide claims data and measured the number of monthly outpatient visits. A negative binomial regression model was fitted to monthly outpatient visits from 2016 to 2019 to estimate the numbers of 2020. The number of all-cause outpatient visits in 2020 was 12% lower than expected. However, this change was relatively stable in outpatient visits for chronic diseases, which was 2% lower than expected. Deficits in all-cause outpatient visits were observed in all months except January; however, deficits in outpatient visits for chronic diseases have rebounded since April 2020. The levels of change in healthcare utilization were observed differently among disease groups, which indicates that the impacts of the pandemic were disproportionate. This study calls for a policy response to emerging and reemerging infectious diseases, as the findings confirm that a health crisis, such as the COVID-19 pandemic, could disrupt the healthcare system. Assessing the mid-to long-term impacts of COVID-19 on healthcare utilization and health consequences will require further research.

Abstract	Objective: As the fourth wave of COVID-19 spread in South Korea in 2022, society experienced various adverse effects, including COVID-19 phobia, depression, and loneliness. Addressing these factors became a vital part of the anti-COVID-19 individual and public mental health efforts, conducted partly by fostering COVID-19 knowledge, attitudes, and compliance with public prevention practice guidelines under the controversial policy of living “with COVID-19”. Method: The study used a cross-sectional online survey-based design. Participants comprised a convenience sample of Korean university students ( n = 460). A survey was distributed to the participants to measure their agreement/disagreement with the policy “with COVID-19” and a structural equation model and path analysis to examine the impact of the latent variables of COVID-19 phobia and COVID-19 knowledge, attitudes, and practice as of April 2022. Results: The mean COVID-19 phobia score was 48.13/100, with psychological and social phobia scores higher than in previous studies, while psychosomatic and economic phobia scores were lower than in previous research. Higher psychological phobia significantly increased COVID-19 practices and attitudes. Conversely, higher psychosomatic phobia decreased practices and attitudes. Moreover, higher psychological phobia was significantly associated with disagreement with the policy. Conclusion: The results suggest that efforts to increase South Korean university students’ acceptance of easing COVID-19 restrictions should focus on mitigating psychological phobia.

Abstract	Background and objective: Different languages and versions of the COVID-19 Phobia Scale (C19P–S) have been developed and tested in several countries. Chinese college students are a large vulnerable group and are susceptible to psychological problems during the COVID-19 pandemic. However, no studies had yet examined the reliability and validity of the C19P–S in China among college students group. This study aims to evaluate the COVID-19-related phobia of Chinese college students and examine the reliability and validity of this scale. Methods: A total of 1689 Chinese college students participated in this study from April 27 to May 7, 2022. They finished the online questionnaire including demographic information and C19P–S. Cronbach's alpha and split-half reliability were used to examine the internal consistency of the scale. Confirmatory factor analysis was further used to examine the scale's construct validity. Convergence validity was also confirmed. Results: This scale in Chinese had high reliability and validity. The Cronbach's alpha and split-half reliability of the total scale were 0.960 and 0.935, respectively. The construct validity-related indicators of the total scale met the standards (RMSEA = 0.064, IFI = 0.907, TLI = 0.906, and CFI = 0.907). Regarding the subscales, the composite reliability (CR) and average variance extracted (AVE) also met the cutoff values (CR > 0.7 and AVE >0.5). Comparison between gender groups showed that total and subscale scores between male and female students differed significantly. Conclusion: The Chinese version of the C19P–S was appropriate for evaluating phobic symptoms among Chinese college students. Therefore, this tool could be used to evaluate the mental health of college students in the future.

Abstract	Background: Social engagement serves as the foundation for social connections by providing a sense of belonging, social identity, and fulfillment. Previous studies have mainly focused on the one-way relationship between social engagement and subjective health among older individuals, and little attention has been paid to their mutual relationship. Therefore, this study aimed to examine the mutual association relationship between social engagement and their subjective health in older Koreans. Methods: Seven waves of data samples (aged ≥60 years) from 2006 to 2018 from the Korean Longitudinal Study of Aging (KLoSA) was used in this study. Descriptive analysis, chi-squared tests, 2-year lagged Generalized estimating equation (GEE) model, and cross-lagged panel model were performed to investigate the mutual association between social engagement and subjective health among six survey periods. Results: Results of the GEE model revealed when controlling for other variables, older Koreans who reported good subjective health only had a higher OR (1.678 vs. 1.650, p < 0.001) of participating in social engagement than those who had bad subjective health in 2006–2008 period; the occurrence rate of more social engagement was significantly higher among older adults with good subjective health than among those with bad subjective health (five out six survey periods). Cross-lagged analysis showed similar results that coefficients of social engagement on subjective were relatively larger in three survey periods; coefficients of subjective health on social engagement were relatively larger in the other three survey periods. The impact of social engagement on subjective health might be greater than that of subjective health on social engagement. Conclusion: All-around participation and engagement of older people in society have become a consensus among the international community. In view of the single social engagement activities and less relevant participation channels in Korea, government departments should consider not only ...

Abstract	Official responses to the COVID-19 pandemic have prioritized information disclosure. Timely and comprehensive information released by the authorities is conveyed mainly through dashboards, which can better inform the public and help them prepare for the pandemic. However, there is limited evidence regarding the COVID-19 dashboard data presentation for South Korea, China, and Japan. This study aimed to describe the current COVID-19 situation in the three countries and compare the information disclosure content on their COVID-19 dashboards. Based on the COVID-19 data released and updated by each country’s official authorities, two dashboard websites used by many people in each country were selected. We conducted content analysis and developed a checklist (39 items in five categories: cases, testing, vaccines, health information, and additional items) based on the structure of each country’s COVID-19 dashboard website to assess COVID-19 information disclosure. Japan experienced the worst outbreak among the three countries. They all provided basic dynamic data displayed on the dashboard, while the performance in key categories varied substantially between the countries (South Korea: 30/39 items; China: 25/39 items; Japan: 30/39 items). Moreover, as part of the publicly accessible information recorded by each nation, there were differences in the key indicators published and important facts disclosed. Improvement in reporting techniques and disclosure methods will help countries communicate more effectively with the public and conduct more efficient public health research.

Abstract	To investigate the knowledge, preventive practices, and depression of Chinese university students living in South Korea and Mainland China during the COVID-19 outbreak and explore the determinants of depression among these students, an online cross-sectional questionnaire survey was conducted from 23 March to 12 April 2020. The online questionnaire included questions on knowledge and preventive practices related to COVID-19, and the Patient Health Questionnaire-9 was used to diagnose depressive symptoms. A total of 420 Chinese university students were finally included in the study (171 students from South Korea and 249 students from Mainland China). The majority of these students had a good level of knowledge of COVID-19. Students living in South Korea displayed better preventive practices than those living in Mainland China; however, the proportion of students (28.7%) with moderate-to-severe depression in this group was relatively higher than that (18.9%) of the Mainland Group (χ 2 = 5.50, p < 0.05). More severe depression was related to high levels of concern about family members and contracting COVID-19 as well as suspecting themselves of having come into contact with patients. Displaying more preventive behaviors decreased the depressive symptoms in both groups. These data could be used as a reference for further studies in different regions to take measures (e.g., psychological counseling and encouragement for physical activities) to reduce depressive symptoms in university students.

Abstract	Human immunodeficiency virus (HIV) testing is important to HIV prevention, treatment, and care. We aimed to assess the role of sociodemographic, behavioral factors and HIV knowledge on HIV testing among people aged 15−49 years in Nepal. The 2011 Nepal Demographic and Health Survey data was used for secondary data analysis. Herein, 9843 women and 3017 men who had experienced coitus were included. The respondents were asked if they underwent HIV testing and received the test results in their lifetime. Chi-square test and multivariate logistic regression analysis were applied at 5% level of significance. Adjusted odds ratios and 95% confidence intervals were computed separately for women and men. Of the total, 18.0% of men and 7.4% of women had been tested for HIV in their lifetime. As compared to the age of 15 to 24 years, males aged 25 to 29 years were more likely to report, whereas females aged 35 to 49 years were less likely to report HIV testing. Lower caste groups had more likelihood of reporting HIV testing than the other caste in both sexes. The odds of being tested for HIV were significantly higher among those who had higher education in both sexes. There was significant positive association between HIV testing and economic status in males whereas this association was reverse among females. The male respondents who spent more than one month away from home in the last 12 months were 1.68 times more likely to have been tested for HIV in their lifetime. Having multiple sexual partners was associated with higher odds of testing for HIV in both sexes. Having comprehensive HIV knowledge was independently associated with the reporting of higher odds of HIV testing in females. Promotion of HIV testing should consider sociodemographic factors, sexual behavior, and imparting comprehensive HIV knowledge.

Abstract	BackgroundPopulation aging—the inevitable increase in the percentage of older adults—is occurring all around the world as the fertility rate declines and life expectancy rises. This study examined the relationship between socioeconomic status (SES), mental health, and the need for long-term services and support (LTSS) among Korean older adults. It also aimed to provide evidence-based information for South Korea's long-term support services and programs.MethodsThis study used the data on older adults aged over 60 years from the 2018 Korean Longitudinal Study of Aging (KLoSA). Ultimately, 5,527 older adults were included in the database (42.6% men, 57.4% women). To clarify the association between SES, mental health, and the need for LTSS among older Korean men and women, chi-squared test, t-test, and structural equation modeling (SEM) were performed.ResultsThe SEM analysis showed that a significant, negative association was observed between SES and the need for LTSS among these older adults—the higher SES groups would generally have less need for LTSS. Mental health had a strong, negative impact on the need for LTSS—better mental health status of the older individuals would indicate a lower need for LTSS, and the effect was stronger among older men. Meanwhile, the positive relationship between SES and mental health was verified—the higher the SES of these older adults the better their mental health.ConclusionsGender- and social class-sensitive impacts of mental health on the need for LTSS were observed in this study. These findings could provide an evidence-based reference for interventions targeting different genders and social classes in Korea's long-term care system, such as the enhancement of social welfare and mental health status of the older adults.

Abstract	Health financing strategies contribute significantly to containing the outbreak of the Coronavirus disease 2019 (COVID-19). This study aims to reassess Korea’s financing strategies in response to COVID-19 in 2020, to ascertain its effects and sustainability. The Joint External Evaluation tool was adopted to analyze the data collected from government reports, official statistics, and other sources. Findings show that Korea could maintain a low incidence and fatality rate compared with other countries, at low costs. It was a result of rapidly procured healthcare resources based on laws and policies established after the 2015 epidemic, and the National Health Insurance. However, to achieve long-term sustainability, it is important to enhance the financial stability of the national health insurance and increase the proportion of the public sector in healthcare resources.

Abstract	This study aimed to assess the prevalence and correlates of condom use at last sexual intercourse among people aged 15–49 years in Nepal. Secondary data analysis was performed using the Nepal Demographic and Health Survey 2011. The study was restricted to the respondents who reported ever having had sexual intercourse; 9843 females and 3017 males were included. Condom use was assessed by asking if respondents used condoms in their most recent sexual intercourse. Chi-square test and multivariate logistic regression analysis were performed using Complex Sample Analysis Procedure to adjust for sample weight and multistage sampling design. Overall, 7.6% of total, and 16.3% of males and 6.2% of females reported using condoms in their last sexual intercourse. Living in Far-Western region, age and wealth quintile were positively associated with condom use in both males and females. Being unmarried was the most important predictor of condom use among males. Higher education was associated with increased likelihood of condom use in females. However, mobility, having multiple sexual partners, and HIV knowledge were not significant correlates of condom use in both sexes. A big difference was observed in the variance accounted for males and females; indicating use of condoms is poorly predicted by the variables included in the study among females. Condom use was more associated with sociodemographic factors than with sexual behavior and HIV knowledge.
