Depression, anxiety, and stress in Korean general population during the COVID-19 pandemic

Determinants of future anxiety across individual, household, and regional levels in South Korea using a social ecological model

This study is the first to examine the determinants of future anxiety in South Korea using the Social Ecological Model (SEM). It aimed to show that, beyond individual factors, mezzo- and macro-level aspects, particularly those related to housing, may influence anxiety. Utilizing 2018 data from the Korean Health Panel Survey, we employed a three-level multilevel analysis to investigate how these factors contribute to the perception of future anxiety among Koreans. Our findings reveal that future anxiety is influenced by a complex interplay of demographic and socio-economic factors, including gender, age, health status, economic stability, living conditions, and regional socio-economic indicators. Notably, the study highlights the significant role of household-level factors, such as income and housing status, in shaping individuals' anxieties about the future. Additionally, regional characteristics like housing vacancy rates and suicide rates are found to have an impact, suggesting the importance of broader socio-economic and cultural contexts in understanding future anxiety. Given South Korea's socio-economic challenges, including the real estate crisis and demographic shifts, our study underscores the need for targeted policies to alleviate future anxiety, enhance mental well-being, and promote a more equitable society.

Current status of modifiable risk factors for cardiovascular disease in Korean women

Hypertension, diabetes mellitus, dyslipidemia, obesity, and smoking are the primary modifiable risk factors contributing to the increasing morbidity and mortality rates from cardiovascular disease (CVD) among Korean women. Significant sex-related differences exist in the prevalence, awareness, treatment, and control of these risk factors, highlighting the importance of age- and sex-specific approaches to the management and prevention of CVD. Notably, the prevalence of hypertension and diabetes mellitus increases with age, with a higher prevalence in elderly women compared to men. Dyslipidemia and obesity are also trending upward, particularly in postmenopausal women, highlighting the impact of menopause on cardiovascular risk. The present review advocates for improved diagnostic, therapeutic, and educational efforts to mitigate the risk of CVD among Korean women, with the goals of reducing the overall burden of the disease and promoting better cardiovascular health outcomes.

Factors Associated With Negative Life Changes due to COVID-19 Among Older Adults Residing in an Urban Low-Income Neighborhood in Korea: Focused on Gendered Differences

This study examined negative life changes due to coronavirus disease of 2019 (COVID-19) and its correlates in a sample of community-dwelling older adults from a low-income urban city in Korea, focusing on gendered differences. Negative life changes due to COVID-19 were categorized into four domains: behavioral/physical, psychosocial, goal-seeking, and control/freedom. Being female, not receiving basic livelihood security, and dissatisfaction with housing situation were significantly associated with negative life changes during the pandemic. Gender-stratified analyses revealed that most within-gender social disparities associated with changes due to COVID-19 occurred in older women. The odds of experiencing negative changes were higher among working women and those receiving security income aid. In low-income urban communities, those who were previously socially and economically active perceived more negative changes owing to the pandemic. The contribution of gender to negative life changes should be considered to effectively alleviate concerns among older adults during pandemics.

The Collaborative Outcome Study on Health and Functioning during Infection Times (COH-FIT): Results from Cyprus

Many studies have shown that COVID-19 caused many problems in mental health. This paper presents the results of the Cyprus sample, part of the global initiative named "The Collaborative Outcomes Study on Health and Functioning during Infection Times" (COH-FIT). Methods: The study took place from April 2019 to January 2022, using the Greek version of the online standard COH-FIT questionnaire on 917 Cypriot adults. Weighted t-tests were applied to test the differences between pre-pandemic and intra-pandemic scores using the anesrake package. Results: Participant responses indicated a significant negative impact of the pandemic on measures of mental health (-7.55; 95% CI: -9.01 to -6.07), with worsening in the scores for anxiety (12.05; 95% CI: 9.33 to 14.77), well-being (-11.06; 95% CI: -12.69 to -9.45) and depression (4.60; 95% CI: 2.06 to 7.14). Similar negative effects were observed for feelings of anger (12.92; 95% CI: 10.54 to 15.29), helplessness (9.66; 95% CI: 7.25 to 12.07), fear (22.25; 95% CI: 19.25 to 25.26), and loneliness (12.52; 95% CI: 9.94 to15.11). Increased use of social media (0.89; 95% CI: 0.71 to 1.09), internet (0.86; 95% CI: 0.67 to 1.04), and substance consumption (0.06; 95% CI: 0.00 to 0.11) were reported, along with a significant decrease in physical health (-3.45; 95% CI: -4.59 to -2.32), self-care (-7.10; 95% CI: -9.00 to -5.20), and social function (-11.27; 95% CI: -13.19 to -9.35), including support (-0.72; 95% CI: -1.09 to -0.34) and family function (-7.97; 95% CI: -9.90 to -6.05). Conclusions: The COVID-19 pandemic significantly affected the daily life and emotional well-being of Cypriots. Identifying factors that influence vulnerability and resilience is essential to prioritize mental health support and address the long-term effects of the pandemic.

Long COVID in Pakistan: a cross-sectional analysis of health and psychosocial outcomes

According to the World Health Organization-led Delphi consensus, long COVID corresponds to the occurrence of symptoms beyond twelve weeks after the onset of acute COVID-19 illness that cannot be explained by alternate diagnosis. This cross-sectional study aimed to analyse the impacts of long COVID on general health and psychosocial well-being. For this study, the participants were interviewed either face to face or via telephone, and their responses were recorded on a questionnaire capturing information on demographics, COVID-19 status, duration of symptoms and long COVID symptoms. The psychosocial impacts of the pandemic were assessed using scales like Short Mood and feeling questionnaire (sMFQ), Warwick-Edinburgh Mental Well-being Scale (WEMWBS), Generalized Anxiety Disorder Assessment (GAD-7) and Perceived Stress Scale (PSS). Regression analysis was conducted to analyse the predictors of long COVID. A total of 300 participants were interviewed, of which 155 (52%) had COVID-19 illness. Of these 54 (35%) had persistent symptoms for a period of more than 12 weeks classified as long COVID. Muscle problems and fatigue were the most frequent (14.7%) symptoms encountered, followed by breathing problems (12.6%) and cognitive issues (12.6%). The symptoms of decrease in appetite and confusion or disorientation during the initial phase of the infection were associated with long COVID. The majority of the participants (83.3%) had moderate level of perceived stress, while moderate to severe levels of stress were observed in 17.3% of the individuals. Moreover, a high level of positive mental well-being was also observed. This study highlights the need for further research into the clinical aspects and implications of long COVID in Pakistan and emphasizes the importance of ongoing support for affected individuals.

Incidence of Panic Disorder Diagnoses After Celebrity Disclosures of Panic Disorder in South Korea

Importance

The persistent stigma associated with mental health conditions is a major challenge worldwide. Celebrities may improve this by openly discussing their own mental health issues, potentially influencing public attitudes and encouraging individuals to seek treatment for these conditions.

Objective

To evaluate the impact of celebrity mental health disclosures on the incidence and prevalence of panic disorder diagnosis in South Korea.

Design, Setting, and Participants

This cohort study included the entire South Korean population from January 2004 to December 2021, as reflected in the National Health Insurance Service data. Analysis was conducted from May 2022 through January 2024.

Exposure

Time periods analyzed included the timeframe before (from January 2004 to December 2010) and after the public disclosures of panic disorder by 3 high-profile Korean celebrities between December 2010 and January 2012 (from January 2011 to December 2021).

Main Outcomes and Measures

Monthly incidence and prevalence of panic disorder, defined by the presence of a clinical diagnosis of the condition. Trends were assessed using interrupted time series analysis with autoregressive integrated moving average models. To assess public interest in panic disorder, trends in search data were analyzed, examining the association between the timing of increased searches and changes in the incidence and prevalence of panic disorder. Data on obsessive-compulsive disorder (OCD) were included as a control.

Results

The study covered the entire population of South Korea, including 48 559 946 individuals in January 2004 and 52 593 886 individuals in December 2021. Before 2011, the mean (SD) annual prevalence of panic disorder was stable at 560 (140) persons per 100 000 persons per year. The celebrity disclosure in December 2010 was associated with higher monthly incidence rates of panic disorder, as measured by insurance claims data, changes that were observed in both the level (5.8 persons; 95% CI, 2.2-9.5 persons) and slope (0.78 persons per month; 95% CI, 0.19-1.40 persons per month) per 100 000 persons. By 2021, the observed annual prevalence per 100 000 persons reached 7530 persons, an increase of 775.6% compared with the 860 persons (95% CI, 330-1400 persons) estimated if the disclosures had not occurred. Internet searches anticipated changes in monthly prevalence with a lag of 2 or 3 months (F = 4.26, P = .02 and F = 3.11, P = .03, respectively). The celebrity disclosures had no significant association with the incidence or prevalence of OCD.

Conclusions and Relevance

In this observational cohort study, celebrity disclosure of mental health conditions was associated with a sustained reduction in stigma, as reflected in increased help-seeking behavior for the condition over more than a decade. This underscores the influential role celebrities can play in shaping public health perceptions and behaviors, offering valuable insights for the development of future mental health policies and public awareness campaigns.

The Prevalence of Depression among the Global Public in the Context of the COVID-19 Epidemic: A Systematic Review and Meta-Analysis

Background

We aimed to analyze the prevalence of depression among the global public during COVID-19, identify its influencing factors in order to provide reference, and help safeguard public mental health.

Methods

A comprehensive literature on global public depression in various countries during the COVID-19 pandemic was obtained through electronic searches of PubMed, Web of Science, and other databases, combined with literature tracing from Dec 2019 to Mar 2023. Then a meta-analysis was conducted using the random effects model by Stata 16.0. The heterogeneity was evaluated by I2 . Subgroup analysis, sensitivity analysis, and meta-regression analysis were used to explore the sources of heterogeneity and the factors influencing public depression. Egger's test was used to test publication bias.

Results

Overall, 68 articles with 234,678 samples were included in the study. Analysis revealed that the overall prevalence of depression among the population during COVID-19 was 32.0% (95% CI: 29.0%-35.0%). Of these, marital status (OR=0.65, 95% CI: 0.47-0.87), presence of infected cases (OR=2.45, 95% CI: 1.82-3.30), and fear of being infected by the virus (OR=9.31, 95% CI: 6.03-14.37) were the main factors influencing people's depression and the main source of heterogeneity.

Conclusion

The prevalence of depression among the global public is at a high level during COVID-19. The prevalence of depression among people unmarried, divorced, or widowed, surrounded by infected cases, contact infection cases, and worried about being were higher than others.

Pandemic stressors and mental health indicators in eight countries

PURPOSE

The Covid-19 pandemic has exacted a significant physical, financial, social, and emotional toll on populations throughout the world. This study aimed to document the association between pandemic stressors and mental health during the pandemic across countries that differ in cultural, geographic, economic, and demographic factors.

METHODS

We administered an online survey randomly in Brazil, China, Germany, Egypt, India, Indonesia, Nigeria, and the United States from September 2020 to November 2020. This survey included questions on Covid-19-related stressors as well as the Patient Health Questionnaire-2 and the Primary Care PTSD Checklist to screen for depression and post-traumatic stress disorder (PTSD) symptoms, respectively. We performed bivariable and multivariable regression analyses to assess the prevalence and odds ratios of overall depression symptoms and probable PTSD and in relation to stressors across countries.

RESULTS

Among 8754 respondents, 28.9% (95% CI 27.5-30.0%) experienced depression symptoms, and 5.1% (95% CI 4.5-6.0%) experienced probable PTSD. The highest prevalence of depression symptoms was in Egypt (41.3%, 95% CI 37.6-45.0%) and lowest in the United States (24.9%, 95% CI 22.3-27.7%). The highest prevalence of probable PTSD was in Brazil (7.3%, 95% CI 5.6-9.4%) and the lowest in China (1.2%, 95% CI 0.7-2.0%). Overall, experiencing six or more Covid-19-related stressors was associated with both depression symptoms (OR 1.90, 95% CI 1.46-2.48) and probable PTSD (OR 13.8, 95% CI 9.66-19.6).

CONCLUSION

The association between pandemic related stressors and the burden of adverse mental health indicators early in the Covid-19 pandemic transcended geographic, economic, cultural, and demographic differences between countries. The short-term and long-term impacts of the pandemic on mental health should be incorporated in efforts to tackle the consequences of Covid-19.

Impact of Omicron-Variant SARS-CoV-2 Infection on Depression and Anxiety: A Community-Based Study in Korea

OBJECTIVE

This study seeks to evaluate the association between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the severity of depression and anxiety in the Korean community during the period dominated by the Omicron variant.

METHODS

We used data from the 2022 Daejeon Mental Health Survey, involving data of 985 participants aged 19-69 years. The data collected included SARS-CoV-2 infection experience, days post-infection, and depression and anxiety symptoms evaluated using the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder Questionnaire-7, respectively. Additionally, physical health, social activity status, and sociodemographic characteristics such as gender, age, marital status, educational level, and household income were collected. The association between SARS-CoV-2 infection and depression and anxiety were examined. Further analyses explored association between days post- infection and the severity of depression and anxiety.

RESULTS

There was no significant correlation between SARS-CoV-2 infection and depression and anxiety in the overall population. Notably, participants under 50 years of age exhibited a transient worsening of depression and anxiety, followed by a decrease in symptoms within 40 days. Participants aged 51 years and older showed no significant change in depression and anxiety.

CONCLUSION

This study discerned transient effects of Omicron variant infection on depression and anxiety, particularly in younger individuals. A prospective study encompassing a larger sample size is imperative to investigate the influence of SARS-CoV-2 infection on depression and anxiety.

Protective Behaviors Against COVID-19 and Related Factors in Korean Adults With Depressive Symptoms: Results From an Analysis of the 2020 Korean Community Health Survey

OBJECTIVE

This study evaluated protective behaviors against coronavirus disease-2019 (COVID-19) and related factors in individuals with depressive symptoms.

METHODS

This cross-sectional study included data from the 2020 Korean Community Health Survey. Depressive symptoms, COVID- 19 protection behaviors, and related factors were investigated in 228,485 people. Chi-square test and logistic regression analysis were used to analyze categorical variables. Statistical analysis was performed using SPSS software (version 27.0).

RESULTS

In the study, 3.9% (n=8,970) had depressive symptoms. The prevalence of depressive symptoms was higher in individuals in their 19-39 years , and ≥60s than in those in their 40-59 years (p<0.001). Lower education level and household income were associated with a higher prevalence of depression (p<0.001). Among the various occupations, service workers had the highest prevalence of depressive symptoms (p<0.001). Individuals with depressive symptoms were less likely to adopt protective behaviors against COVID-19 (p<0.001) or exhibit concerns regarding death and economic damage (p<0.001) compared to individuals without depressive symptoms. Individuals with depressive symptoms were more likely to have unhealthy behaviors than those without depressive symptoms (p<0.001). Individuals with depressive symptoms considered that the COVID-19 response by the government and other organizations was inadequate (p<0.001).

CONCLUSION

During the COVID-19 pandemic, individuals with depressive symptoms faced greater challenges in adopting protective behaviors. Therefore, it is crucial to develop strategies to protect people with depressive symptoms during another pandemic in the future.

Is social support associated with postpartum depression, anxiety and perceived stress among Korean women within the first year postpartum?

PURPOSE

This study aimed to examine the association between social support, postpartum depression (PPD), anxiety and perceived stress among women within 12 months of childbirth in South Korea.

METHODS

A cross-sectional, web-based survey was conducted from 21 to 30 September 2022 and included women within 12 months of childbirth in Chungnam Province, South Korea. A total of 1486 participants were included. Multiple linear regression models were used to evaluate the association between social support and mental health.

RESULTS

In total, 40.0% of the participants had mild to moderate PPD; 12.0%, anxiety symptoms; and 8.2%, perceived severe stress. Social support (from family and significant others) is significantly associated with PPD, anxiety and perceived severe stress. Current maternal health problems, unplanned pregnancy and low household income were risk factors for PPD, anxiety and perceived stress. The increase in the time elapsed after childbirth showed a positive association with PPD and perceived severe stress.

CONCLUSIONS

Our findings provide insights to identify at-risk mothers and emphasize the importance of social support in families, early screening and continuous monitoring for postpartum women to prevent PPD, anxiety and stress.

Risk and protective factors of mental health during the COVID-19 pandemic: A cross-sectional study in Singapore

Introduction

The main aims of the study were to: establish the average levels of psychological distress, suicidality and positive mental health (PMH); and examine their associated risk and protective factors in the population of Singapore during the early phase of the COVID-19 pandemic.

Method

Participants from a national psychiatric epidemiological study conducted in the general population of Singapore from 2016 to 2018, who had agreed to be re-contacted, were invited to participate in the study that was conducted from May 2020 to June 2021. Questionnaires assessing psychological distress, causes of stress, resilience and PMH were administered.

Results

A total of 1,129 respondents completed the study. The mean age was 47.7 (standard deviation = 16.5) years. The prevalence of stress, depression and anxiety was 7.1%, 8.0% and 8.4%, respectively. The final pathways model showed that high concerns related to possible COVID-19 infection of family members or friends were significantly associated with higher stress (β = 0.242, P<0.001), depression (β = 0.152, P=0.001) and anxiety (β = 0.280, P<0.001). High resilience was significantly associated with lower stress (β = -0.482, P<0.001), depression (β = -0.394, P<0.001) and anxiety (β = -0.516, P<0.001), and with high PMH (β = 0.498, P<0.001).

Conclusion

The findings highlight the negative impact of fear of COVID-19 infection, social distancing and isolation on the mental health of the population. Resilience and PMH were associated with lower psychological stress, and interventions to improve these characteristics can enhance mental health and well-being.

Differences in Functional Level and Central Symptom of Network Structures in the Patients Seeking Treatment for Panic Disorder Before and During the COVID-19 Pandemic

OBJECTIVE

Mental health problems such as anxiety, panic, and depression have been exacerbated by the coronavirus disease-2019 (COVID-19). This study aimed to compare the symptom severities and overall function before and during the COVID-19 pandemic among patients with panic disorder (PD) seeking treatment compared to healthy controls (HCs).

METHODS

Baseline data were collected from the two groups (patients with PD and HCs) in two separate periods: before COVID-19 (Jan 2016-Dec 2019) and during COVID-19 (Mar 2020-Jul 2022). A total 453 participants (before COVID-19: 246 [139 patients with PD and 107 HCs], during COVID-19: 207 [86 patients with PD and 121 HCs]) was included. Scales for panic and depressive symptoms and overall function were administered. Additionally, network analyses were performed to compare the two groups within the patients with PD.

RESULTS

The results of two-way analysis of variance analyses showed that patients with PD enrolled during COVID-19 showed higher levels of interoceptive fear and lower overall functioning. In addition, a network comparison test revealed that a significantly high strength and expected influence for agoraphobia and avoidance in patients with PD during COVID-19.

CONCLUSION

This study suggested that the overall function could have worsened, and the importance of agoraphobia and avoidance as a central symptom may have increased in patients with PD seeking treatment during COVID-19.

Prevalence of Mental Disorders and Associated Factors in Korean Adults: National Mental Health Survey of Korea 2021

OBJECTIVE

Mental health is a global concern and needs to be studied more closely. We aimed to estimate the prevalence of mental disorders and their associated factors among the general population in Korea.

METHODS

The National Mental Health Survey of Korea 2021 was conducted between June 19 and August 31, 2021 and included 13,530 households; 5,511 participants completed the interview (response rate: 40.7%). The lifetime and 12-month diagnosis rates of mental disorders were made using the Korean version of the Composite International Diagnostic Interview 2.1. Factors associated with alcohol use disorder (AUD), nicotine use disorder, depressive disorder, and anxiety disorder were analyzed, and mental health service utilization rates were estimated.

RESULTS

The lifetime prevalence of mental disorders was 27.8%. The 12-month prevalence rates of alcohol use, nicotine use, depressive, and anxiety disorders were 2.6%, 2.7%, 1.7%, and 3.1%, respectively. The risk factors associated with 12-month diagnosis rates were as follows: AUD: sex and age; nicotine use disorder: sex; depressive disorder: marital status and job status; anxiety disorder: sex, marital status, and job status. The 12-month treatment and service utilization rates for 12-month AUD, nicotine use disorder, depressive disorder, and anxiety disorder were 2.6%, 1.1%, 28.2%, and 9.1%, respectively.

CONCLUSION

Approximately 25% of adults in the general population were diagnosed with mental disorders during their lifetime. The treatment rates were substantially low. Future studies on this topic and efforts to increase the mental health treatment rate at a national level are needed.

Socio-economic factors associated with mental health outcomes during the COVID-19 pandemic in South Korea

Background

Individuals are at an increased risk of adverse mental health outcomes during the COVID-19 pandemic. To reduce the impact on mental health outcomes that were induced by national-level policies, which may influence an individual at the community level, exploring the comprehensive relations between individual and environmental factors are needed. The aim is to examine socio-ecological factors associated with mental health outcomes, including depressive and anxiety symptoms, with the perspective of support to provide interventions that help the community during future disease outbreaks.

Method

From 5 November to 20 November 2020, a cross-sectional and population-based study was conducted to assess the socio-ecological factors of mental health outcomes during the COVID-19 pandemic. A total of 1,000 participants, aged 20-69 years, in Chungnam Region, South Korea, were included in this study. Multiple linear regression models were used to examine the association between socio-ecological factors and mental health outcomes. The primary outcomes were individuals' mental health outcomes which are measured by PHQ-9 and GAD-7 scores.

Results

Of the 1,000 participants, the average PHQ-9 was 4.39, and GAD-7 was 3.21 during the COVID-19 pandemic. Specifically, the participants with moderate or severe levels of PHQ-9 and GAD-7 were 12.6 and 6.8%, respectively. Higher levels of depressive and anxiety symptoms were associated with participants who were single, reported a lower household income, had decreased support from friends or family, and increased stress from the workplace or home. In subgroup analyses by age, gender, and household income, a similar trend was reported in individual and interpersonal-level factors. There were significant associations between regional-level factors, including gross regional domestic product (GRDP), mental health institutions, psychiatrists, nurse-to-population ratios, and individuals' mental health outcomes.

Conclusion

The management of depressive and anxiety symptoms of individuals during the pandemic was better explained by individual and interpersonal characteristics rather than regional-level factors, highlighting the need for more policies aimed at these lower levels.

Factors associated with depressive symptomatology during the COVID-19 pandemic in Mexico: A 2021 national survey

BACKGROUND

Previous studies have identified a set of variables associated with depression during the COVID-19 pandemic. However, the existing antecedents in Mexico, in addition to being limited to the beginning of the health emergency, made use of small and unrepresentative samples. Therefore, the aim of the present study was to identify the prevalence and factors associated with clinically significant depressive symptomatology (CSDS) in a representative Mexican sample of 2021.

METHODS

A secondary cross-sectional analysis of the Encuesta Nacional de Bienestar Autorreportado (ENBIARE) was conducted. For the present study, the effective sample was 30,901. Univariate and bivariate anaylses were followed by a multiple Poisson regression, which served to obtain adjusted prevalence ratios of each variable under study.

RESULTS

The prevalence of CSDS in the year 2021 was 15.3 %. In the multivariable analysis, the factors associated with CSDS were the number of recent stressful events, having a major functional limitation, not having social support from family or friends, being female, having suffered recent discrimination, alcohol or other drug use (by oneself or someone at home), not being married or cohabiting, living in a rural area, having had a diagnosis of COVID-19, having lost a job, living with a chronic patient, not doing physical exercise, and having a low educational level.

LIMITATIONS

The main limitations were the cross-sectional nature of the data, the use of self-report measures, as well as the fact that this was a secondary analysis that did not allow consideration of additional variables.

CONCLUSIONS

A set of personal and contextual variables were identified that can help focus prevention and intervention efforts on the phenomenon of depression.

Depression and anxiety in later COVID-19 waves across Europe: New evidence from the European COvid Survey (ECOS)

We aimed to investigate the prevalence of probable depression and anxiety and their correlates during later stages of the COVID-19 pandemic in eight European countries. Longitudinal data (wave 7 in June/July 2021: n=8,032; wave 8 in September 2021: n=8,250; wave 9 in December 2021/January 2022: n=8,319) were used from the European COvid Survey - a representative sample of community-dwelling adults from several European countries (Germany, United Kingdom, Denmark, Netherlands, France, Portugal, Italy and Spain). In wave 7 (wave 8; wave 9), 23.8% (22.0%; 24.3%) of all respondents had probable depression and 22.6% (22.1%; 23.7%) had probable anxiety. These prevalence rates substantially differed between the European countries. Regressions showed that emerging difficulties with the income were associated with both increases in depressive symptoms and anxiety symptoms. An increase in one's own perceived risk of getting infected with the SARS-CoV-2, the birth of a child and an increase in the Covid-19 stringency index were associated with increases in depressive symptoms. The significance of probable depression and anxiety during later stages of the COVID-19 pandemic in eight European countries was highlighted. Avoiding income difficulties may also contribute to mental health.

Association of compliance with COVID-19 public health measures with depression

Although previous studies have demonstrated increased depression related to COVID-19, the reasons for this are not well-understood. We investigated the association of compliance with COVID-19 public health measures with depression. Data from the 2020 Korea Community Health Survey were analyzed. The main independent variable was compliance with rules based on three performance variables (social distancing, wearing a mask in indoor facilities, and outdoors). Depression was assessed using Patient Health Questionnaire-9 scores. Of 195,243 participants, 5,101 participants had depression. Bad and moderate performance scores for compliance were associated with depression (Bad score, men: adjusted odds ratio [aOR] = 2.24, 95% confidence interval [CI] = 1.29-3.87; women: aOR = 2.42, 95% CI = 1.42-4.13; moderate score, men: aOR = 1.31, 95% CI = 1.02-1.68; women: aOR = 1.28, 95% CI = 1.07-1.53). In the subgroup analysis, among the quarantine rules, not wearing a mask indoors was the most prominently associated with depression. In participants with a high level of education, non-compliance with quarantine rules was significantly associated with depression. People who do not comply with public health measures are more likely to be depressed. The preparation and observance of scientific quarantine rules can help mental health in the ongoing COVID-19 pandemic and another infectious disease pandemic that may come.

Assessing Knowledge, Preventive Practices, and Depression Among Chinese International Students and Local Korean Students in South Korea During the COVID-19 Pandemic: An Online Cross-Sectional Study

Depression among university students and international university students is an increasing problem globally. This study aimed to clarify the differences on the conditions and determinants of the knowledge, preventive practices and depression of the Chinese international students and local Korean students in South Korea during the COVID-19 pandemic. An online cross-sectional questionnaire including general demographic characteristics, COVID-19-related knowledge, preventive practice, and the Patient Health Questionnaire (PHQ-9) was applied from March 23 to April 22, 2020. A total of 533 university students (171 Chinese international students and 362 local South Korean students) were included in the study. The majority of both Chinese international students and local South Korean students had a good comprehension of COVID-19. Chinese international students in South Korea showed better preventive practice than local Korean students, while the proportion of moderate to severe depression of Chinese international students was relatively higher (28.07%) than that of local Korean students (22.38%). Determinants of depression of Chinese international students in South Korea were information satisfaction, likelihood of survival after infection, symptoms of a cough and feelings of discrimination, while for local Korean students were gender, educational level, family, suspected symptoms, self-assessed physical health status, COVID-19 detection, population contact history and online sources of information. These results could be used as a reference for decreasing the depressive symptoms among the university students.
