The prevalence of depressive symptoms, anxiety symptoms and sleep disturbance in higher education students during the COVID-19 pandemic: A systematic review and meta-analysis

Health and health literacy among social work students in Germany: A cross-sectional health survey

A university is a living environment that can influence people's health. This study aims to analyze health and health literacy of Bachelor of Social Work (BSW) students in comparison with students in other study programs. A survey was conducted among all students at the University of Kassel regarding their health and health literacy. The survey evaluated general health status, disability, and health literacy. In this study, BSW students had an adverse health status compared to other students. Only 66.9% of the BSW students rated their general health as very good or good (vs. 79.7% in other study programs). BSW students are also more likely to be moderately or severely limited in daily activities due to chronic health conditions than students in other study programs. In contrast, health literacy levels differ little between BSW students and other students. This study highlights the need for health (literacy) promotion in social work studies.

Functional Connectivity Alterations Associated with COVID-19-Related Sleep Problems: A Longitudinal Resting-State fMRI Study

Background

COVID-19 has led to reports of fatigue and sleep problems. Brain function changes underlying sleep problems (SP) post-COVID-19 are unclear.

Purpose

This study investigated SP-related brain functional connectivity (FC) alterations.

Patients and methods

Fifty-five COVID-19 survivors with SP (COVID_SP) and 33 without SP (COVID_NSP), matched for demographics, completed PSQI and underwent rs-fMRI at baseline and 2-month follow-up. Correlations between FC and clinical data were analyzed by Pearson correlation analysis with Gaussian random field (GRF) correction. The repeated-measures analysis of variance (R-M ANOVA) was completed to explore the interaction with time.

Results

At baseline, COVID_SP exhibited elevated FC: right precentral gyrus (PrG) with left lateral occipital cortex (LOcC)/right PrG, left inferior parietal lobule (IPL) with right superior frontal gyrus (SFG), left hippocampus with right inferior frontal gyrus (IFG). Higher FC between left hippocampus and right SFG correlated with PSQI scores. At 2-month follow-up, decreased FC implicated in emotion regulation, executive function, and memory; increased FC in semantics, attention, and auditory-visual processing. The changes in these regions are correlated with the scores of PSQI, GAD, and PHQ. The Repeated-Measures Analysis of Variance (R-M ANOVA) revealed a significant time interaction effect between sleep and various emotion scales. Moreover, the analysis of the functional connectivity between the right PrG and the right PrG as well as that between the left IPL and the right SFG also discovered a significant time interaction effect.

Conclusion

This study provides insight into the changes in brain function associated with SP after COVID-19. These changes may partially explain the development of SP, and they also changed over time.

Echoes of Strain: A Two-Year Longitudinal Study on the Impact of China's Zero-COVID Policy on College Students' Insomnia and Depressive Symptoms

Purpose

In China, stringent and long-lasting infection control measures, which were called "dynamic zero-COVID policy", have significantly affected the mental health of college students, particularly concerning depressive and insomnia symptoms. This study aims to investigate how depressive and insomnia symptoms evolved among Chinese college students throughout the pandemic, including the beginning and end of the dynamic zero-COVID policy period.

Patients and Methods

We conducted a 2-years longitudinal survey involving 1102 college students, collecting data at three key time points. Depressive symptoms were assessed using the Patient Health Questionnaire-9, and insomnia symptoms were measured with the Youth Self-rating Insomnia Scale-8. Three contemporaneous symptom networks and two cross-lagged panel networks were constructed.

Results

In the current sample, the prevalence of clinically significant depressive symptoms was 6.1%, 8.9%, and 7.7% during the first, second, and third waves, respectively. The prevalence of clinically significant insomnia symptoms was 8.1%, 13.0%, and 14.1%. Over time, the severity of depressive and insomnia symptoms and network density increased, persisting at least one year after the pandemic and control measures ended. "Difficulty initiating sleep" bridged the two disorders, while "anhedonia" played a pivotal role in triggering and sustaining other symptoms.

Conclusion

This study underscores the lasting impact of the evolving zero-COVID policy on depressive and insomnia symptoms among college students, elucidating the underlying interaction mechanisms. There is a pressing need for a more comprehensive evaluation of the implementation of restrictive public policies, taking into account their potential long-term consequences.

Students supporting students: evaluating the impact of the COVID-19 pandemic on resident assistant mental health

OBJECTIVE

To examine the impact of the novel coronavirus SARS-CoV2 (COVID-19) pandemic on Residents Assistants (RA) at a public university in the Midwest.

PARTICIPANTS

Sixty-seven RAs that had been offered an RA position for the '20-'21 academic year.

METHODS

An online cross-sectional survey measuring socio-demographics, stress, and well-being was fielded. MANCOVA models evaluated the impact of COVID-19 on well-being of Current RAs and compared to the non-current RA groups.

RESULTS

Sixty-seven RAs provided valid data. Overall, 47% of RAs had moderate-severe anxiety and 86.3% had moderate-high level of stress. Current RAs perceiving a great impact of COVID on life had significantly more stress, anxiety, burnout, and secondary traumatic stress than those who did not. RAs who started then quit experienced significantly higher secondary trauma compared to Current RAs.

CONCLUSIONS

Further research is needed to better understand the experiences and of RAs and to develop policies and programs to support RAs.

The impact of short-term exposure to criteria air pollutants on sleep disturbance among young adults: A nationwide analysis in 261 Chinese cities

BACKGROUNDS

Evidence concerning the short-term acute effect of air pollution on sleep health is quite limited. This study aims to examine the association between short-term exposure to ambient criteria air pollutants (CAPs) and sleep disturbance among young adults.

METHODS

A nationwide retrospective study was conducted across 261 Chinese cities from 2023 to 2024. Participants' sleep quality was assessed by the Pittsburgh Sleep Quality Index, and air pollutant concentrations were collected during the study period. Distributed lag nonlinear models were utilized to assess the effect of CAPs on sleep disturbance and seven sleep quality components over the seven days preceding the survey (lag 0-7). Stratification analyses involving gender, cigarette smoking, and hazardous drinking behavior were performed.

RESULTS

Of 12,279 young adults, 39% were identified as having sleep disturbances. Increases of 10 μg/m3 in PM2.5, PM10, O3, and NO2 exposure were linked to a heightened risk of sleep disturbance, with the maximum single-day percentage changes being 8.3% (95% confidence intervals: 1.9-15.2%), 10.0% (1.2-19.6%), 6.0% (2.3-9.8%), and 23.6% (4.5-46.0%), respectively. A 10 μg/m3 elevation in PM2.5, PM10, and O3 were associated with 18.4%-34.8% of cumulative increase in sleep disturbance risk. Additionally, a 10 μg/m3 increase in PM2.5 and PM10 concentrations prolonged sleep latency by 3 and 4.8 min, respectively. Each 10 μg/m3 increase in PM10 and O3 shortened sleep duration by 5.4 and 5.7 min. NO2 exposure increased scores on the daytime dysfunction component of the PSQI, resulting in a percentage change of 23.9%. The association between PM2.5, O3, and NO2 exposure and sleep disturbance was stronger in subpopulations with cigarette smoking behavior.

CONCLUSION

Short-term exposure to PM2.5, PM10, O3, and NO2 is significantly associated with sleep disturbance among young adults. Sustained improvements in air quality may help improve sleep health.

Anxiety, depression, and insomnia among medical and non-medical students in Jordan: a cross-sectional study

Background

Depression, the leading cause of disability worldwide, has worsened due to the COVID-19 pandemic, with key risk factors including age, gender, and socioeconomic status. Jordan is experiencing an increase in mental health issues, particularly among children, adolescents, and university students, yet negative attitudes and structural barriers limit access to mental healthcare This study provides a comprehensive analysis of depression, anxiety, and sleep quality among Jordanian undergraduate students.

Methods

This cross-sectional study was conducted between December 2023 and March 2024. The study used the Generalized Anxiety Disorder scale (GAD-7), the Patient Health Questionnaire (PHQ-9), and the Insomnia Severity Index (ISI) to evaluate these mental health factors. Data collection involved a self-administered survey, distributed online and in paper format. Multiple linear regression was utilized to pinpoint significant predictors.

Results

A total of 1181 participants completed the survey, with an average age of 20.43 years. Among the respondents, 74.2% were female, and 35.1% were medical students. Predictors of GAD-7 scores included year of study for medical students, with PHQ-9 scores and male gender serving as negative predictors. For non-medical students, both PHQ-9 and ISI scores positively predicted higher GAD-7 scores. ISI scores were positively influenced by age and PHQ-9 scores for medical students, whereas for non-medical students, age, PHQ-9, and GAD-7 scores were positive predictors.

Conclusion

The study demonstrates that non-medical students experience higher levels of depression, insomnia, and anxiety than their medical counterparts. These findings highlight the necessity for targeted mental health interventions and awareness programs for all undergraduate students.

Self-efficacy and healthy lifestyle behaviors as mediators between COVID-19 care knowledge and health status

The COVID-19 epidemic has affected the psychological well-being and daily life of college students, leading to a decrease in their quality of life. Health status can be influenced by a variety of factors. This study aims to assess the current health status of university students and explore the relationships among COVID-19 care knowledge, self-efficacy, healthy lifestyle behaviors, and health status and how these factors are influenced. Among the 1694 participants, 49.4% were male, 50.6% were female, and 82.2% were freshmen. The results revealed that health status across all dimensions decreased to some extent. COVID-19 care knowledge affected both physical and mental component summaries. The results suggest that improving COVID-19 care knowledge, strengthening self-efficacy, and promoting the development of healthy lifestyle behaviors can positively impact their health status. Here, we explore the health status of college students with COVID-19 infection and the factors and mechanisms that influence it to guide health interventions to better meet the challenges posed by future outbreaks.

The inequitable psychological impacts of the COVID-19 pandemic on post-secondary students with preexisting health conditions: A longitudinal study

Objective: Evidence suggests young adults in post-secondary school experienced increased distress during the COVID-19 pandemic, but students' experiences likely varied. Effects may have also changed over time as students adapted. This study examined the mental health of students with and without preexisting health conditions at two points during the pandemic (winter 2020/2021 and spring/summer 2021). Methods: Participants (N = 1465) completed a baseline and follow-up questionnaire assessing their health history, depressive symptoms, anxiety symptoms, stress, and COVID-19-related worry and perceived vulnerability of severe infection. Results: At both time points, students with preexisting health conditions reported greater distress than those without preexisting health conditions. Stress increased from time 1 to time 2 for all students, and participants with preexisting health conditions significantly increased in their COVID-19 perceived vulnerability of severe infection over time. Conclusions: Findings highlight the need for additional and ongoing mental health supports for vulnerable students throughout the pandemic.

Resilience, Stress, and Mental Health Among University Students: A Test of the Resilience Portfolio Model

In recent years, post-secondary students' mental health has become an important public health concern. However, studies examining protective factors of mental health among students and during challenging times are limited. Guided by the strength-based Resilience Portfolio Model and following a group of undergraduates (N = 1004) throughout the 2020/2021 academic year, this study examined multiple domains of resilience internal assets and external resources and simultaneously tested multiple protective mechanisms for student mental health using structural equation modelling. Results provided support for insulating effects: both internal assets such as emotion regulation and external recourses such as social network supportiveness and cultural fit in university (i.e., perceived congruity between students' personal and cultural selves and their university environment) were associated with reducing academic stress which in turn promoted student mental health at the end of the academic year. There was also support for additive effects: greater cultural fit in university was also directly related to better end-of-year student mental health. As cultural fit in university was associated both directly and indirectly with student mental health, creating an inclusive university community may help reduce student academic stress, lower student psychological distress and improve student subjective well-being.

Development of the psychopathological vulnerability index for screening at-risk youths: a Rasch model approach

Accumulating research on mental health emphasizes the general factor of psychopathology (p-factor) that unites various mental health issues. This study develops a psychopathological vulnerability assessment for youths, evaluating its psychometric properties and clinical utility. An umbrella review conceptualized multifactor psychopathological vulnerability, leading to a 57-item pool. A total of 11,224 individuals participated in this study. The resulting 22-item psychopathological vulnerability index (PVI) fitted the unidimensional Rasch model, demonstrating a person separation reliability of 0.78 and a Cronbach's alpha of 0.84. Cut-off points of 11 and 5, derived from latent class analysis, were used to distinguish vulnerable and high-protection populations. The PVI's concurrent and predictive hit rates ranged from 36.00% to 53.57% in clinical samples. The PVI concretized the vulnerability-stress model for identifying at-risk youths and may facilitate universal interventions by integrating the theoretical foundations of bifactor S-1 models with key symptoms from network models for theoretically grounded approaches.

University students' sleep during the COVID-19 pandemic in the State of Hawai'i

Objectives: This study assessed undergraduates' sleep in Hawai'i during the COVID-19 pandemic and whether demographic characteristics, health locus of control, substance use and campus features related to sleep outcomes. Implications are considered for programs to support students' sleep and health during pandemic conditions. Participants: About 1,288 undergraduate students from six universities in Hawai'i. Methods: Surveys assessing sleep, emotional wellbeing, ethnicity, body mass index, locus of health control, and substance use. Results: Students' reported increased sleep time but decreased sleep quality during the pandemic. Sleep disruption related to anxiety, depression, ethnicity, substance use, BMI, health locus of control, class rank, and whether students lived at home. All campuses were associated with disrupted sleep, regardless of size, location, religious affiliation, term structure, or method of instruction. Conclusions: In response to public health crises, such as the COVID-19 pandemic, all Hawai'i universities should screen students for sleep disruption, emotional adjustment, social isolation and substance misuse. Programs to promote sleep and behavioral health appear particularly warranted for graduating seniors, Pacific Islanders, students with high BMI, and students who commute to college.

Evaluating the mental health of international students in the U.S. during the COVID-19 outbreak: The case of University of Florida

Objective: The study aims to capture the emotional challenges faced by international students due to the changes in U.S. visa regulations during the COVID-19 outbreak. Participants: 165 international students from University of Florida participated in the study. Methods: We conducted a cross-sectional online survey using previously validated questionnaire tools (PHQ-9 and GAD-7). The collected data was quantitatively analyzed through different statistical approaches, including ANOVA, Independent Sample t-Test, and Binary Logistic Regression. Results: 18.8% of our study sample had a moderately severe to severe depressive status, and 20.6% of the study sample had severe anxiety. Additionally, there was a statistically significant difference in the depression and anxiety scores based on gender. Conclusions: Our findings addressed the importance of taking serious measures when emotionally impactful political issues arise to prevent the development of mental illnesses among international students at U.S. institutions of higher education.

The evaluation of depressive, anxiety symptoms and sleep disturbance in college students post- pandemic era across UAE: a multicentric survey

The COVID-19 epidemic has had a significant worldwide impact, requiring measures such as quarantine, social isolation, and the closing down of educational institutions, increasing concerns about student safety. This study evaluated the mental health and sleep status of 201 college students in the UAE after the epidemic. The sample consisted primarily of females (72.1%) and students aged 21-23 years (42.3%), with the majority residing in Dubai (62.7%). The findings revealed unsettling levels of insomnia risk and significant gender variations in emotional states, with females displaying higher degrees of distress. These findings underscore the negative consequences of the pandemic on student well-being and the importance of having access to mental health care, as well as calling for specialized treatments to address the individual needs of various student groups.

Perceived Causes of Sleep Problems in Higher Education Students: An Exploratory Study

The major purpose of the present study was to explore higher education students' perceptions of the causes of their sleep problems. The data were drawn from a previous cross-sectional online survey, from which only the questions relevant to this study were selected, including items on sleep disturbances and their causes. The participants included 1519 full-time students (76% women), aged 18-30 years (M = 20.9, SD = 2.3); 95.3% were single and studying for a Bachelor's degree (75.2%) across diverse fields of study. Overall, 30% of the students reported suffering from insomnia, 17.8% met the criteria for clinical insomnia (according to the Insomnia Severity Index), and 12.5% reported being dissatisfied with their sleep. The most significant perceived causes of sleep difficulties were stress (85%), academic problems (67%), and general worries (56.5%). Other causes included affective/love problems (28.4%), family issues (27.5%), changes in sleeping habits (25.9%), financial problems (13.7%), transition to higher education (10.4%), pain (7.1%), and general illness (5.5%). These findings may have important implications for interventions aimed at improving sleep health among higher education students.

Cross-country comparison of depressive symptoms and social-emotional aspects in university students from Brazil and Germany during the COVID-19 pandemic: results from two cross-sectional surveys

BACKGROUND

The COVID-19 pandemic negatively affected students' mental health, increasing pre-existing psychosocial vulnerabilities. University students worldwide have presented differences in their mental health status; however, cross-country studies comparing students' mental health during the pandemic are lacking.

AIMS

To investigate potential differences between university students from Brazil and those from Germany with respect to (a) depressive symptoms and alcohol and drug consumption, (b) social and emotional aspects (loneliness, self-efficacy, perceived stress, social support and resilience) and (c) attitudes towards vaccination.

METHOD

Two online cross-sectional studies were conducted with university students during the COVID-19 pandemic in Brazil (November 2021 to March 2022) and in Germany (April to May 2022). Depressive symptoms, alcohol consumption, loneliness, self-efficacy, perceived stress, social support, resilience, sociodemographic information and attitudes towards vaccination were assessed. Data were analysed using univariate and bivariate models.

RESULTS

The total sample comprised N = 7911 university students, with n = 2437 from Brazil and n = 5474 from Germany. Brazilian students presented significantly more depressive symptoms and suicidal thoughts, higher levels of perceived stress, higher frequency of drug or substance consumption, and lower levels of perceived social support and resilience than German students, whereas German students presented higher levels of loneliness than Brazilian students. A more favourable opinion towards vaccinations in general was found among Brazilian students compared with German students.

CONCLUSIONS

In both countries, low-threshold (online) counselling targeting university students is needed. The differences between the samples could indicate country and/or cultural differences which justify further research in this area.

Differentiating anxiety profiles in medical students: a latent profile analysis

Previous studies have confirmed a high prevalence of anxiety among medical students. The present study aimed to identify distinct medical student anxiety profiles to develop targeted interventions. A cross-sectional study was conducted with 735 medical students (346 males and 389 females) recruited voluntarily from mainland China. Latent profile analysis (LPA) was applied to explore profiles of various types of anxiety, including test anxiety, academic anxiety, social anxiety, career choice anxiety, general anxiety, and trait anxiety. The results showed that LPA yielded four profiles, comprising 17.14, 20.82, 21.50, and 40.54% of the sample respectively. Specifically, Class 1 (17.14%) showed the highest levels of multiple types of anxiety, particularly the highest level of general anxiety. Class 2 (20.82%) and Class 3 (21.50%) showed moderate levels of anxiety, but they displayed different patterns across various types of anxiety except for social anxiety. Class 4 (40.54%) displayed the lowest levels of anxiety across all types. These profiles differed in academic status and depression. Further, the multinomial logistic regression analysis showed that the high-anxiety group (Class 1) was more likely to be elder students, with lower sports frequency and a higher degree of self-handicapping. These results call for the need to move beyond linear relations among global constructs to address the complexity of anxiety coping and highlight the importance of customized intervention for these heterogeneous groups.

TikTok use versus TikTok self-control failure: Investigating relationships with well-being, academic performance, bedtime procrastination, and sleep quality

With the global rise of TikTok popularity, the research on how TikTok use may affect its users is still limited. We aimed to contribute to this research by taking a novel approach: distinguishing between general TikTok use (duration and frequency) and TikTok self-control failure. We expected that using TikTok when it conflicts with other important goals or tasks (TikTok self-control failure) would be more strongly and negatively linked to well-being, academic performance, bedtime procrastination, and sleep quality as compared to general TikTok use. We tested our expectations in two samples: adolescents (N1 = 249) and university students (N2 = 222) during the COVID-19 pandemic lockdown. We found interesting relationships between TikTok use, TikTok self-control failure, and the outcome variables. However, our hypothesis was confirmed in both studies only for bedtime procrastination. We argue that this might be because bedtime procrastination could be a more 'proximal' outcome variable compared to the other tested variables. The present research offers empirical data useful for discussions regarding the potential negative effects of TikTok use on young people. It also shows that differentiating between general measures of social media use (i.e., duration and frequency) and a measure of social media self-control failure might provide more detailed insights into the relationships between variables of interest for media researchers.

Sleep health, its intraindividuality, and perceived stress in college students during the COVID-19 pandemic

Objective: To describe the changes in sleep health domains and examine the associations between the repeated measures and intraindividual variability (IIV) of these domains and perceived stress. Participants: A diverse racial and ethnic group of first-year college students (N = 23, 78.3% female, aged 17-18) attending in-person classes during the COVID-19 pandemic. Methods: Sleep health domains were determined using 7-day wrist actigraph and daily sleep diaries, and perceived stress scale was completed at 1-month intervals across 3 months. Results: Sleep timing, regularity, and alertness during daytime demonstrated statistically significant changes between three timepoints. Greater stress was associated with more irregularity (B = 2.25 [.87-3.62], p < .001), more dissatisfaction in sleep (B = .04 [.02-.19], p < .01), alertness during daytime (B = .18 [.05-.31], p < .001), and greater IIV (ie, fluctuations) in sleep satisfaction (B = .083 [.02, .15], p < .01). Conclusion: These findings offer insights for future researchers to facilitate intervention development to promote mental and sleep health among college students.

Mental Health Among First-Year Students Transitioning to University in Australia: A Longitudinal Study

Objectives: Young people attending university for the first time may be at heightened risk of experiencing mental health problems. However, limited research has examined the mental health experiences of this cohort using longitudinal methods. This study aimed to examine mental health symptoms prior to commencing university, estimate changes in symptoms over the course of the first semester of study, and identify factors associated with initial symptom levels and changes. Methods: Australian first-year undergraduate students (N = 340) were recruited via social media and participated in a four-wave online longitudinal study conducted between February and June 2021. Symptoms of depression, anxiety, and psychological distress were assessed at each wave, along with psychosocial and lifestyle factors. Demographic characteristics were assessed at baseline. Results: Latent growth curve models indicated no significant linear change over time for depression (p = .26) or anxiety (p = .83) symptoms. However, a significant effect of time was observed for psychological distress (p = .03), indicating higher distress levels at wave 3 compared to baseline (p = .004). Financial stress, pressure to succeed, difficulty coping, greater loneliness, and more negative social interactions were each significantly associated with higher baseline depression, anxiety, and distress scores. Only greater loneliness and more negative social interactions were found to be associated with a greater increase in depression over time. Conclusion: The findings indicate that transition to university was not generally associated with an increase in poor mental health. However, several factors were associated with poorer mental health immediately prior to university commencement. Assisting students to manage financial distress, facilitating the development of social connections among students with limited social networks and skills training targeting coping and the development of realistic academic expectations may help support student mental health and promote improved wellbeing during transition to university.

Depressive symptoms and its multifaceted associated factors among young men who have sex with men facing the dual threats of COVID-19 and mpox in China

INTRODUCTION

The COVID-19 pandemic has significantly impacted the mental health of human beings since 2020, especially the young people and the pre-existing marginalized groups such as men who have sex with men (MSM). During the COVID-19 pandemic, the multi-country outbreak of mpox in 2022 additionally posed a significant stress on the most-affected communities (i.e., MSM). This study investigated the level of depressive symptoms and its multifaceted associated factors among Chinese young men who have sex with men (YMSM) in this unique period.

METHODS

In September 2022, a large-scale cross-sectional survey was conducted among YMSM aged 18-29 years across six representative provinces in China. Hierarchical regression analysis was performed to test the various types of associated factors of depressive symptoms.

RESULTS

Among the 2493 participants, 65.6 % (n = 1638) reported mild to severe depressive symptoms. The hierarchical regression analysis identified that depressive symptoms was significantly positively associated with unemployment, having substance use in the past 6 months, a higher level of MSM self-stigma, incompletion of COVID-19 vaccination, greater mpox risk perception, and presence of mpox related-like symptoms.

LIMITATIONS

This study used the facility-based sampling method to recruit the participants, which may lead to selection bias.

CONCLUSIONS

Chinese YMSM faced significant mental health challenges during the concurrent epidemics of COVID-19 and mpox, which was associated with their socio-economic status, risk behaviors, stigma, and multiple diseases-related variables. Proactive measures may hold promise as effective strategies for mitigating mental distress among marginalized groups during public health crises.

Videoconferencing During the COVID-19 Pandemic is Associated with Sleep Disruption in Young Adults

Purpose

The COVID-19 pandemic resulted in a shift to working and learning from home and a concomitant rise in the use of virtual communication technology, such as videoconferencing. The current study prospectively examined the association between videoconferencing and sleep in a sample of young adults attending a university during the pandemic. The effects of videoconferencing on health and wellness outcomes and academic performance were also evaluated.

Patients and Methods

Participants completed the core Consensus Sleep Diary and reported engagement in videoconferencing, the use of electronic devices, and physical activity daily for 8 consecutive days. They also completed baseline measures of sleep, communication technology use, physical activity, and mental distress, as well as released their end-of-term GPA. Results were evaluated via multilevel modeling and path analysis.

Results

Participants with a heavier videocall volume lost 17 m of sleep and suffered nearly a 1% reduction in sleep efficiency for each additional hour of videoconferencing compared to those with a lower call volume. They also tended to spend more time awake during the night, have earlier sleep midpoints, and report worse sleep, although those trends did not reach statistical significance. For everyone, including individuals with lower videocall volume, earlier sleep midpoints, lower sleep quality, somewhat shorter sleep, and higher fatigue were reported on days with a relatively high videocall load compared to days with a low videocall load. Increased academic engagement with videoconferencing predicted lower academic performance and higher psychological distress: Both relationships were mediated by sleep. Use of videoconferencing for personal reasons, however, was directly associated with a reduction in distress.

Conclusion

Videoconferencing is an important determinant of sleep and may impact health and wellness as well as academic outcomes in young adults. The effects of virtual communication on sleep and human behavior warrant further study in this and other populations.

Move more today, sleep better tonight? Daily associations between physical activity and sedentary behavior with sleep among young adults with and without insomnia symptoms

OBJECTIVE

At the between-person level, it is well-documented that individuals with more physical activity (PA) and less sedentary behavior (SB) tend to have better sleep outcomes than their peers. However, the associations at the within-person level remain unclear. This study investigated the daily associations between PA and SB with nighttime sleep among young adults with and without insomnia symptoms.

METHODS

Data was collected through activity trackers and online questionnaires for 7 consecutive days among 147 university students, including time spent on moderate to vigorous physical activity (MVPA), light physical activity (LPA), and SB, along with sleep duration, sleep efficiency, and sleep quality. Participants were classified into two subgroups according to the presence of insomnia symptoms, which were determined by a self-reported insomnia scale. Multilevel compositional data analysis was conducted on the total sample, and separately on subsamples characterized by the presence and absence of insomnia symptoms.

RESULTS

In the total sample and subsample without insomnia symptoms, substitutions among MVPA, LPA, and SB were not associated with changes in sleep outcomes at the daily level. However, in the subsample with insomnia symptoms, days with more MVPA or SB and less LPA were associated with higher sleep efficiency, while days with more LPA at the expense of MVPA or SB were associated with lower sleep efficiency.

CONCLUSIONS

For young adults with insomnia symptoms, replacing LPA with MVPA on a given day may improve their sleep efficiency that night.

COVID-19 Pandemic Increases the Risk of Anxiety and Depression among Adolescents: A Cross-Sectional Study in Rural West Bengal, India

About 14% of adolescents experience mental illnesses globally. The rate increased after the COVID-19 pandemic. This study aimed to estimate the prevalence of COVID-related major mental illnesses (depression and anxiety) and their predictors among adolescents. This community-based cross-sectional study was conducted among 350 adolescents aged 10-19 years, recruited from rural communities in West Bengal, India. The study areas included 27 subcenters in the Budge Budge II Block, which comprised 191,709 population and 45,333 households. Data were collected from randomly selected households by trained research assistants through house-to-house interviews. Pretested standardized questionnaires, Patient Health Questionnaire (PHQ) for depression, Generalized Anxiety Disorder (GAD) for anxiety, and a demographic questionnaire were used for data collection. The prevalence of anxiety was 35.7% (125 out of 350), and the prevalence of depression was 30.0% (105 out of 350). Females had significantly higher scores of anxiety (6.67 ± 4.76 vs. 3.42 ± 3.17, respectively, p < 0.001) and depression (5.51 ± 4.99 vs. 3.26 ± 3.86, respectively, p < 0.001) compared to males. Adolescents who had COVID-19 cases or deaths in the family had significantly higher scores of anxiety and depression compared to those who did not have these events. In multivariate analysis, the statistically significant predictors of anxiety were COVID-19 death in the family, COVID-19 cases in the family, female gender, and a lower income group (p < 0.001 for all). For depression, the significant predictors included COVID-19 death in the family, COVID-19 cases in the family, female gender, a lower income group, and a higher age group in adolescents (p < 0.001 for all). Based on the study results, we recommend that immediate attention is needed for adolescents' mental health support and coping with stresses following COVID-19.

The longitudinal mediating role of sleep in associations between COVID-19 stressors predicting mental and physical health outcomes among emerging adult college students

The current study tested a longitudinal mediation model throughout the COVID-19 pandemic focused on whether students' housing instability stress and food/financial instability stress at the beginning of the pandemic in spring 2020 (T1) informed sleep dissatisfaction and duration in fall 2020 (T2) and, in turn, physical and mental health in spring 2021 (T3). Further, we tested whether relations varied based on students' ethnic-racial backgrounds. Participants included 879 Asian, Black, Latine, Multiracial, and White emerging adult college students (Mage = 19.95, SD = 0.33) from a large public university in the mid-Atlantic region of the United States who attended college during the COVID-19 pandemic and completed surveys about their experiences. Findings indicated a significant mediation process, such that T1 housing instability stress predicted greater T2 sleep dissatisfaction and, in turn, less physical health, greater depressive symptoms, and greater anxiety symptoms at T3. Additionally, T1 food/financial instability stress was significantly associated with less T2 sleep duration but was not, in turn, associated with any T3 outcomes. Findings did not vary by students' ethnicity/race. Results highlight that sleep dissatisfaction is an important factor that accounts for relations between COVID-19 stressors predicting mental and physical health outcomes throughout the pandemic.

Impact of COVID-19 on psychological distress in subsequent stages of the pandemic: The role of received social support

This longitudinal study examined a sample of adult Poles (N = 1245), who were interviewed three times from July 2021 to August 2022, during the later stages of the COVID-19 pandemic. The study had two primary objectives. The first was to assess the impact of the pandemic on psychological distress, measured through symptoms of depression and anxiety. The pandemic's effects were evaluated using three predictors: direct exposure to COVID-19, COVID-19 related stressors, and perceived threats from COVID-19. The second objective was to investigate the role of received social support in coping with the pandemic's hardships. Receipt of social support was measured by both the quantity of help received and the perceived quality of that support. A Latent Growth Curve Model (LGCM) was employed to analyze psychological distress across three waves, controlling for sociodemographic variables, non-COVID life events, coping self-efficacy, and perceived social support. Findings indicated that COVID-19 stressors and COVID-19 threats were strongly and consistently associated with greater psychological distress throughout the study period. The impact of direct COVID-19 exposure was limited. The quantity of received support predicted higher distress, whereas higher quality of received support was linked to better mental health. Crucially, the relationship between the quantity of support and distress was moderated by the quality of support. Effective social support was associated with the lowest distress levels, regardless of the amount of help received. Conversely, receiving large amounts of low-quality support was detrimental to psychological health. In summary, the ongoing psychosocial challenges of COVID-19 significantly eroded mental health, highlighting the importance of support quality over quantity in coping with significant life adversities.

Depressive and anxiety symptoms among university students during the later stages of the COVID-19 pandemic in Germany - Results from the COVID 19 German Student Well-being Study (C19 GSWS)

Introduction

Data on the mental health of university students in Germany during the later stages of the pandemic is still limited. This study aimed to determine (1) the prevalence of anxiety and depressive symptoms among university students 1.5 years after the first COVID-19 restrictions and (2) which factors were associated with these outcomes.

Methods

The cross-sectional COVID-19 German Student Well-being Study (C19 GSWS) collected data of 6,996 students at five German universities. Associations between anxiety and depressive symptoms with sociodemographic and other factors were analyzed using multivariable logistic regression models.

Results

The mean age of the participants was 23.9 years (SD = 4.8), 67% were female and 31% male. The prevalence for depressive symptoms was 29 and 32% for anxiety. The lack of a trusted person and financial difficulties were associated with anxiety and depressive symptoms. Being worried that someone in one's personal network had become severely ill with COVID-19 and concern about (re)infection with COVID-19 were associated with anxiety symptoms. Those with pre-existing health conditions had an up to 1.98-times higher chance for reporting depressive symptoms (OR, 95% CI: 1.01-3.88) and an up to 2.27-times higher chance for anxiety symptoms, respectively (OR, 95% CI: 1.15-4.46).

Conclusion

Concepts for prevention and counseling to tackle mental health problems in students are needed and programs should take specific stressors in times of crises into account.

Factors associated with dental students' mental health during the COVID-19 pandemic: a longitudinal study

The aim of the present study was to examine the relationships between gender, sense of coherence (SOC), social support, perception of academic environment and mental health of dental students during the coronavirus disease 2019 (COVID-19) pandemic. A longitudinal study involving 65 undergraduates enrolled from the first to sixth semesters in the bachelor dental course of Universidade Federal Fluminense, Brazil, was conducted. Baseline data (2018) included age, gender, SOC, social support, stress control and perception of education environment. Depression, anxiety and stress were assessed at baseline (response rate: 93%) and two-year follow-up (2020; response rate: 37%). Structural Equation Modelling was used to test the relationships between independent variables and depression, anxiety and stress during COVID-19 pandemic. Lower social support (β = -0.15), lower stress control (β = -0.20) and lower SOC (β = -0.39) were directly linked to higher depression (β = 0.22). Female gender (β = 0.22), worse perception of educational environment (β = -0.24) and lower SOC (β = -0.57) directly predicted higher anxiety. Female gender (β = 0.18), lower stress control (β = -0.21), and lower SOC (β = -0.46) directly predicted higher stress. The link between gender and both depression and stress, was mediated by stress control. Social support was indirectly linked to depression and stress via SOC. Perception of educational environment mediated the link between SOC and anxiety. Mental health of dental students during COVID-19 pandemic was influenced by demographic characteristics, perception of educational environment, social support and SOC through both direct and indirect pathways.

Impact of distress and anxiety due to COVID-19 on digital addictions in university students in the third wave period

Abstract*

Background

Digital addictions are a major problem worldwide, which has increased considerably during the COVID-19 pandemic. In this scenario, two important impact factors to explain this problem are stress and anxiety because of COVID-19. The objective of this research was to determine the impact of distress and anxiety due to COVID-19 on digital addictions.

Methods

cross-sectional, explanatory study. A total of 802 students from public and private universities residing in the city of Lima and Callao (Peru), with a mean age of 21.68 (SD = 3.11), selected by convenience sampling, participated in the study. The MULTICAGE CAD-4 questionnaire, the distress scale, and the COVID-19 worry scale were applied.

Results

two models examined with structural equation modeling showed good fit indices (CFI and TLI > .95, RMSEA and SRMR < .06). The first model shows that the latent variables distress and anxiety due to COVID-19 have direct effects on digital addictions as a general construct (R 2 = 22%). The second model shows that the exogenous latent variables (stress and anxiety) have direct effects of different magnitudes on each digital technology, so the variance explained on smartphone addiction was higher (R 2 = 25%) with respect to internet (R 2 = 19%) and video game addiction (R 2 = 6%). It was also found that for every male, there are two females with high levels of distress and anxiety. Regarding the problematic use of smartphones and internet, there is a prevalence of 40% regardless of sex; but as for the problematic use of video games, there is a marked difference between males (18.8%) and females (2.7%).

Conclusion

the distress and anxiety caused by COVID-19 have a direct impact in aggravating digital addictions.

Depression, anxiety and coping strategies among Palestinian university students during political violence: a cross sectional study

Background

There are numerous wars and ongoing political violence in Palestine and little is known about how they have affected Palestinian undergraduate students' mental health and coping strategies. This study aimed to assess the prevalence of depression, and anxiety symptoms and coping mechanisms among Palestinian university students during the times of current political violence in Palestine after October 7, 2023.

Methods

A cross-sectional descriptive study design was utilized for a sample of students from 3 universities in Palestine (Al Quds University, Hebron University, and An-Najah University) and 1815 participants responded. Data were collected using self-reported questionnaires, including Hospital Anxiety and Depression Scale (HADS) and Brief COPE scale. Person correlation test, chi-square test, and bivariate analysis were performed to examine the associations between research variables.

Results

The estimated prevalence of depression was 65.9, and 60.9% for anxiety. The logistic regression showed that students from the Arts Faculty, females, and those with working parents were significantly more likely to experience depression and anxiety symptoms. Also, active coping, emotional support, and humor reduced the likelihood of experiencing depression symptoms, while active coping, positive reframing, humor, and acceptance decreased the likelihood of developing anxiety symptoms. Further, the study found that using religion, self-blame, denial, and behavioral disengagement increased the likelihood of depression symptoms while planning, venting, religion, self-blame, denial, and behavioral disengagement increased the likelihood of anxiety symptoms.

Conclusion

The study found that political violence often leads to symptoms of depression and anxiety among undergraduates. Furthermore, the use of maladaptive coping mechanisms increases the likelihood that these symptoms will occur. Providing immediate assistance to university students affected by political violence and conflicts is crucial for their emotional and mental recovery and coping with difficulties.

Examining the Relationship Between Anxiety, Depression, and Gastrointestinal Symptoms Among University Students: A Campus-Wide Survey Analysis

STUDY PURPOSE

This study investigates the relationship between anxiety, depression, and gastrointestinal (GI) symptoms among university students through a comprehensive campus-wide survey.

METHODS

A cross-sectional online survey design was adopted in this study. A total of 437 students from three public medical universities in Saudi Arabia participated in the survey, which assessed anxiety and depression using standardized scales and GI symptoms through a tailored questionnaire.

RESULTS

The findings reveal a significant overlap between mental health disorders and GI symptoms, highlighting that students experiencing high levels of anxiety and depression frequently report GI issues. This correlation underscores the importance of integrated health strategies to address both mental and physical well-being.

CONCLUSION

This study concludes that there is a significant correlation between anxiety, depression, and GI symptoms among university students. This highlights the need for comprehensive and integrated health interventions that address both mental and physical health to improve overall well-being and academic success in this population.

Predicting long-term sleep deprivation using wearable sensors and health surveys

Sufficient sleep is essential for individual well-being. Inadequate sleep has been shown to have significant negative impacts on our attention, cognition, and mood. The measurement of sleep from in-bed physiological signals has progressed to where commercial devices already incorporate this functionality. However, the prediction of sleep duration from previous awake activity is less studied. Previous studies have used daily exercise summaries, actigraph data, and pedometer data to predict sleep during individual nights. Building upon these, this article demonstrates how to predict a person's long-term average sleep length over the course of 30 days from Fitbit-recorded physical activity data alongside self-report surveys. Recursive Feature Elimination with Random Forest (RFE-RF) is used to extract the feature sets used by the machine learning models, and sex differences in the feature sets and performances of different machine learning models are then examined. The feature selection process demonstrates that previous sleep patterns and physical exercise are the most relevant kind of features for predicting sleep. Personality and depression metrics were also found to be relevant. When attempting to classify individuals as being long-term sleep-deprived, good performance was achieved across both the male, female, and combined data sets, with the highest-performing model achieving an AUC of 0.9762. The best-performing regression model for predicting the average nightly sleep time achieved an R-squared of 0.6861, with other models achieving similar results. When attempting to predict if a person who previously was obtaining sufficient sleep would become sleep-deprived, the best-performing model obtained an AUC of 0.9448.

Does tinnitus amplify the effects of healthy eating patterns and physical activity on the sleep disturbance or sleep insufficiency, based on the case study of NHANES survey in the United States

Objective

Exploring whether the presence of tinnitus amplifies the effects of an individual's dietary patterns and physical activity on sleep disturbance or sleep insufficiency.

Study design

This study extracted data from the five National Health and Nutrition Examination Surveys (NHANES) between 2009 and 2018, including individuals who had undergone complete questionnaires on tinnitus, dietary habits, physical activity, and sleep. Multivariate logistic regression, restricted cubic spline (RCS) and subgroup analyses were conducted to explore the associations of dietary habits, physical activity, and tinnitus with sleep disturbance and sleep insufficiency.

Results

A total of 7,440 participants were enrolled in this study, of whom 1,795 participants were evaluated as sleep disturbance (24.13%), and 2,281 were sleep insufficiency (30.66%). With adjusting confounding factors of demographic and socioeconomic variables, among overall population, participants with tinnitus showed a significantly increased risk of sleep disturbance [adjusted odds ratio (aOR) = 2.08, 95% confidence interval (CI): 1.83-2.36), and sleep insufficiency (aOR = 1.31, 95% CI: 1.15-1.49). Poor dietary habits also increased the risk of sleep disturbance (aOR = 1.08, 95% CI: 1.04-1.12), as does lack of physical activity (aOR = 1.14, 95% CI: 1.03-1.27); but neither exposure factors significantly increased the risk of sleep insufficiency. The non-linear trend analyses of RCS found that the influence of exposure factors on sleep disturbance experiencing a steady or small decline trend after rising. In addition, the results of the subgroup analysis showed that in tinnitus patients, poor dietary habits and lack of physical activity both significantly increased the risk of sleep disturbance, and poor dietary habits also increased the risk of sleep insufficiency remarkable, but lack of physical activity did not. In healthy participants, poor dietary habits were only significantly associated the sleep disturbance, while lack of physical inactivity even had a protective effect against sleep insufficiency.

Conclusion

Compared to the general population, tinnitus significantly amplified the effects of poor dietary patterns and physical inactivity on sleep disturbance and sleep insufficiency. For tinnitus patients, adjusting a healthy diet and increasing exercise could more effectively promote their sleep health.

Skill Enactment Among University Students Using a Brief Video-Based Mental Health Intervention: Mixed Methods Study Within a Randomized Controlled Trial

BACKGROUND

Mental health problems are common among university students, yet many students do not seek professional help. Digital mental health interventions can increase students' access to support and have been shown to be effective in preventing and treating mental health problems. However, little is known about the extent to which students implement therapeutic skills from these programs in everyday life (ie, skill enactment) or about the impact of skill enactment on outcomes.

OBJECTIVE

This study aims to assess the effects of a low-intensity video-based intervention, Uni Virtual Clinic Lite (UVC-Lite), in improving skill enactment relative to an attention-control program (primary aim) and examine whether skill enactment influences symptoms of depression and anxiety (secondary aim). The study also qualitatively explored participants' experiences of, and motivations for, engaging with the therapeutic techniques.

METHODS

We analyzed data from a randomized controlled trial testing the effectiveness of UVC-Lite for symptoms of depression and anxiety among university students with mild to moderate levels of psychological distress. Participants were recruited from universities across Australia and randomly assigned to 6 weeks of self-guided use of UVC-Lite (243/487, 49.9%) or an attention-control program (244/487, 50.1%). Quantitative data on skill enactment, depression, and anxiety were collected through baseline, postintervention, and 3- and 6-month follow-up surveys. Qualitative data were obtained from 29 intervention-group participants through open-ended questions during postintervention surveys (n=17, 59%) and semistructured interviews (n=12, 41%) after the intervention period concluded.

RESULTS

Mixed model repeated measures ANOVA demonstrated that the intervention did not significantly improve skill enactment (F3,215.36=0.50; P=.68). Skill enactment was also not found to influence change in symptoms of depression (F3,241.10=1.69; P=.17) or anxiety (F3,233.71=1.11; P=.35). However, higher levels of skill enactment were associated with lower symptom levels among both intervention and control group participants across time points (depression: F1,541.87=134.61; P<.001; anxiety: F1,535.11=73.08; P<.001). Inductive content analysis confirmed low levels of skill enactment among intervention group participants. Participants were motivated to use techniques and skills that were perceived to be personally relevant, easily integrated into daily life, and that were novel or had worked for them in the past.

CONCLUSIONS

The intervention did not improve skill enactment or mental health among students with mild to moderate psychological distress. Low adherence impacted our ability to draw robust conclusions regarding the intervention's impact on outcomes. Factors influencing skill enactment differed across individuals, suggesting that it may be necessary to tailor therapeutic skills and engagement strategies to the individual user. Theoretically informed research involving collaboration with end users is needed to understand the processes underlying skill enactment in digital mental health interventions.

The longitudinal association between physical health and depressive symptoms over eight years: Evidence from the health and retirement study

BACKGROUND

The bidirectional relationship between physical health (PH) and depressive symptoms (DS) remains unclear.

METHODS

Data were extracted from the Health and Retirement Study in the United States. PH was measured with a composite of chronic diseases, functional limitations and difficulties in basic and instrumental activities of daily living, and DS with a modified Center for Epidemiological Studies of Depression. Latent growth curve models (LGCM) were employed to examine how the change in PH or DS affected their mutual trajectories in later life. In addition, multilevel models were utilized.

RESULTS

There were 6144 participants included, with an average age of 69.82 ± 6.85 years at baseline, of whom 3686 (59.99 %) were women. PH scores increased from 5.65 in 2010 to 7.72 in 2018, while depression scores increased from 1.14 to 1.31. LGCM results showed that the initial levels of PH and DS were associated (β = 0.558, P < .001), and the initial level of PH could predict the trajectory of DS (β = 0.089, P < .001). Likewise, the initial level of DS was also related to initial PH (β = -0.563, P < .001) but couldn't predict the trajectory of PH. Furthermore, the slopes of PH and DS were predicted bidirectionally by each other. Two-level logistic models further demonstrated the bidirectional association between PH and DS.

CONCLUSION

There was a bidirectional association between physical health and depressive symptoms, which highlights the necessity of comprehensive health management for older adults with poor physical health or depression symptoms.

A Transdiagnostic Video-Based Internet Intervention (Uni Virtual Clinic-Lite) to Improve the Mental Health of University Students: Randomized Controlled Trial

BACKGROUND

Numerous studies have demonstrated the effectiveness of digital interventions for improving the mental health of university students. However, low rates of engagement with these interventions are an ongoing challenge and can compromise effectiveness. Brief, transdiagnostic, web-based video interventions are capable of targeting key mental health and related issues affecting university students and may be more engaging and accessible for this population.

OBJECTIVE

This study used a 2-arm randomized controlled trial to evaluate the effectiveness of Uni Virtual Clinic-Lite (UVC-Lite), a fully automated, transdiagnostic, web-based video intervention, relative to an attention-control condition. The primary outcomes were symptoms of depression and generalized anxiety disorder. The secondary outcomes included psychological distress, social anxiety symptoms, body appreciation, quality of life, well-being, functioning, general self-efficacy, academic self-efficacy, and help seeking. Program use (intervention uptake and engagement) and satisfaction were also assessed.

METHODS

University students (n=487) with mild to moderate symptoms of distress were recruited from universities across Australia and randomly allocated to receive access to the UVC-Lite intervention or an attention-control condition targeting general health for a period of 6 weeks. UVC-Lite includes 12 modules, each comprising a brief animated video and an accompanying exercise. Of the 12 modules, 7 also included a brief symptom screening quiz. Outcomes were assessed at baseline, postintervention, and 3- and 6-months postintervention.

RESULTS

The primary and secondary outcomes were analyzed on an intention-to-treat basis using mixed models repeated measures ANOVA. The intervention was not found to be effective relative to the control condition on any of the primary or secondary outcomes. While 67.9% (114/168) of participants accessed at least 1 module of the intervention, module completion was extremely low. Subgroup analyses among those who engaged with the program (completed at least 1 video) and those with higher baseline distress (Distress Questionnaire-5 score ≥15) did not reveal any differences between the conditions over time. However, uptake (accessing at least 1 video) and engagement (completing at least 1 video) were higher among those with higher baseline symptoms. Satisfaction with the intervention was high.

CONCLUSIONS

The UVC-Lite intervention was not effective relative to a control program, although it was associated with high satisfaction among students and was not associated with symptom deterioration. Given the challenges faced by universities in meeting demand for mental health services, flexible and accessible interventions such as UVC-Lite have the potential to assist students to manage symptoms of mental health problems. However, low uptake and engagement (particularly among students with lower levels of symptomatology) are significant challenges that require further attention. Future studies should examine the effectiveness of the intervention in a more highly symptomatic sample, as well as implementation pathways to optimize effective engagement with the intervention.

A repeated cross-sectional pilot study of the relationship between perceived a community with shared future for doctor-patient and benefit finding: the mediating role of health self-consciousness and moderating role of anxiety

OBJECTIVE

Since January 8, 2023, China has managed COVID-19 as a Class-B infectious disease, marking the epidemic's transition to a low-level stage. This study analyzes the relationship between the public's perceived a community with shared future for doctor-patient (PCSF), health self-consciousness, benefit finding, and anxiety in this stage. Additionally, it compares changes in these variables across different stages of COVID-19.

METHODS

Using a repeated cross-sectional design, three surveys were conducted respectively in three different stages of COVID-19 in China. Specifically, the first survey was conducted in Beijing, Dalian, Zhengzhou, Heihe, and Shangrao from November 13 to 20, 2021 in the outbreak stage of COVID-19, yielding 1,252 valid responses out of 1,534 collected questionnaires. The second survey was conducted in Dalian, Zhengzhou, Heihe, Shangrao, and Lanzhou from December 1 to 19, 2021 in the stable stage of COVID-19, with 872 valid responses obtained from 1,075 collected questionnaires. The third survey was conducted in Beijing, Dalian, Zhengzhou, Heihe, Shangrao, Lanzhou, and Chengdu from January 29 to February 4, 2023 in the low epidemic level stage of COVID-19, achieving 2,113 valid responses from the 2,461 questionnaires collected.

RESULTS

Unlike in the outbreak stage but similar to the stable stage, the public's anxiety, health self-consciousness and benefit finding decreased while PCSF was improved in the low epidemic level stage. Consistent with both the outbreak and stable stage, PCSF, health self-consciousness, benefit finding, and anxiety showed positive correlations in the low epidemic level stage, with health self-consciousness partially mediating the positive impact of PCSF on benefit finding. Unlike in the stable stage but similar to the outbreak stage, anxiety did not moderate the relationship between PCSF and health self-consciousness in the low epidemic level stage.

CONCLUSIONS

The public's health self-consciousness, benefit finding, and anxiety decreased, while PCSF increased in the low epidemic level stage. Furthermore, PCSF had a greater impact on benefit finding, and anxiety's impact on health self-consciousness was significantly reduced. Across different stages of COVID-19, PCSF directly increased benefit finding and also enhanced benefit finding by improving health self-consciousness. Thus, comprehensive intervention measures are beneficial in the low epidemic level stage.

The association between online learning, perceived parental relationship, anxiety, and depression symptoms among secondary school students: insight from symptom network and cross-lagged panel network approach

INTRODUCTION

Anxiety and depression often co-occur in adolescents, with factors from family and school playing a significant role in the comorbidity. However, network analysis has not examined and clarified the detailed bridge and central symptoms of this comorbidity caused by online learning and perceived parental relationships across different COVID-19 times.

METHODS

Over four months, 2,356 secondary school students completed the Patient Health Questionnaire-9 and Generalized Anxiety Disorder Scale-7. Participants were divided into harmonious and disharmonious groups based on their answers to a question about parental conflicts.

RESULTS

The results indicated that adolescents perceiving more parental conflicts showed a denser comorbidity network after four months of online learning. Significant bridge symptoms decreased from three to two across two waves in the harmonious group, while in the disharmonious group, they increased from two to three. The number of central symptoms increased from one in wave 1 to three in wave 2 for the harmonious group, while four in wave 1 decreased to two in wave 2 for the disharmonious group. Furthermore, the CLPN analysis revealed that the strongest positive cross-lagged edge intensity between symptoms was anhedonia-energy in the harmonious group, with anhedonia being the most trigger symptom. In contrast, for the disharmonious group, guilt-suicide and trouble relaxing-excessive worry were the strongest cross-lagged edge, and trouble relaxing was the most trigger symptom.

CONCLUSION

These findings may have implications for interventions designed to promote adolescent mental health in the context of online learning and parental conflicts.

Prevalence and influencing factors of sleep disorders in medical students after the COVID-19 pandemic

BACKGROUND

The prevalence of sleep disorders among medical students was high during the COVID-19 pandemic. However, fewer studies have been conducted on sleep disorders among medical students after the COVID-19 pandemic. This study investigated the prevalence and factors influencing sleep disorders among Chinese medical students after COVID-19.

METHODS

A total of 1,194 Chinese medical students were included in this study from 9th to 12th July 2023. We used the Self-administered Chinese scale to collect the demographic characteristics. In addition, we used the Chinese versions of the Self-rating Depression Scale (SDS), the Self-rating Anxiety Scale (SAS), and the Pittsburgh Sleep Quality Index (PSQI) to assess subjects' depression, anxiety, and sleep disorders, respectively. The chi-square test and binary logistic regression were used to identify factors influencing sleep disorders. The receiver operating characteristic (ROC) curve was utilized to assess the predictive value of relevant variables for sleep disorders.

RESULTS

We found the prevalence of sleep disorders among medical students after COVID-19 was 82.3%. According to logistic regression results, medical students with depression were 1.151 times more likely to have sleep disorders than those without depression (OR = 1.151, 95% CI 1.114 to 1.188). Doctoral students were 1.908 times more likely to have sleep disorders than graduate and undergraduate students (OR = 1.908, 95% CI 1.264 to 2.880).

CONCLUSION

The prevalence of sleep disorders among medical students is high after COVID-19. In addition, high academic levels and depression are risk factors for sleep disorders. Therefore, medical colleges and administrators should pay more attention to sleep disorders in medical students after the COVID-19 pandemic. Regular assessment of sleep disorders and depression is essential.

Age-specific disparity in insomnia among COVID-19 patients in Fangcang shelter hospitals: a population-based study in Shanghai, China

Background

Fangcang shelter hospitals are quarantine facilities offering primary medical treatment for mild and asymptomatic SARS-CoV-2 cases. Little is known about the age-specific prevalence of insomnia among patients in Fangcang shelter hospitals, particularly in older age groups.

Methods

This cross-sectional study was conducted in the three largest Fangcang shelter hospitals during the lockdown period, from March to May 2022, in Shanghai. The patients' demographic and medical information was recorded. Insomnia was defined according to the prescriptions for zolpidem and estazolam. The overall and age-specific prevalence and the risk factors of insomnia were investigated through regression models.

Results

A total of 2,39,448 patients were included in this study (59.09% of the patients were male, the median age was 42, and 73.41% of the patients were asymptomatic), with the prevalence of insomnia being 3.1%. The prevalence of insomnia varied across different age groups (<18 years: 0.23%, 18-64 years: 2.64%, and ≥65 years: 10.36%). SARS-CoV-2 vaccine, regardless of the number of doses, was significantly associated with a decreased risk of insomnia for the group aged ≥65 years. Three doses of the vaccine reduced the risk of insomnia for patients aged 18-64 years. An extra day in the hospital significantly increased the risk of insomnia by approximately 10% for all age groups. Mild symptoms were significantly associated with a higher risk of insomnia among patients aged <65 years old, while being male and residing in the surrounding area were negatively associated with insomnia for all adults.

Conclusion

This study observed that older patients were a high-risk population for developing insomnia in Fangcang shelter hospitals. SARS-CoV-2 vaccination might decrease the risk of insomnia in adults, especially the older adult, which indicates the benefits of vaccination for reducing insomnia among infected patients.

Exploring the interconnections of anxiety, depression, sleep problems and health-promoting lifestyles among Chinese university students: a comprehensive network approach

Background

Anxiety, depression, and sleep problems are prevalent comorbid mental disorders among university students. The World Health Organization (WHO) emphasized a mental health promotion objective, recommending the consideration of protective health-promoting factors in strategies aimed at preventing mental disorders. Integrating theoretically significant constructs (such as protective factors) enhances our comprehension of the intricate mechanisms that underpin mental disorders. This study employed network analysis to first identify core and bridge symptoms within comorbid mental disorders and then explore how health-promoting lifestyles (HPLs) were associated with these disorders. The ultimate goal is to offer health promotion recommendations to enhance students' quality of life.

Methods

A total of 3,896 qualified university students participated in this study. Anxiety, depression, sleep problems, and HPLs were assessed using the GAD-7, PHQ-9, PSQI, and HPLP-II scales. A Gaussian Graphical Model was used to construct the networks. The Network Comparison Test was applied to determine whether the associations between HPLs and comorbid symptoms vary by gender, educational level, family sibling, and mental health status.

Results

Low energy (PHQ4) had the highest strength centrality, followed by Daytime dysfunction (PSQI7) and Trouble relaxing (GAD4). Five bridge symptoms were identified: Daytime dysfunction (PSQI7), Self-harm even suicide (PHQ9), Sad mood (PHQ2), Low energy (PHQ4), and Feeling afraid (GAD7). Regarding protective HPLs, Physical activity, Spiritual growth, and Stress management generally emerged as the top three central mental health-promoting behaviors.

Conclusion

Targeting core and bridge symptoms with timely and appropriate interventions can alleviate anxiety, depression, and sleep problems in this population. Moreover, promoting physical activity, fostering spiritual growth, and managing stress are likely to significantly enhance the overall mental health of university students.

University Students with Current Suicidal Ideation and Perceived Changes during the COVID-19 Pandemic: A Qualitative Study

INTRODUCTION

Mental health problems seemed to have increased among university students during the COVID-19 pandemic. To deepen our understanding of the pandemic's effects in this population, we conducted qualitative research to investigate any perceived changes in students during the pandemic, differentiating the sample based on the presence or absence of current suicidal ideation (SI).

METHODS

A wide sample of Italian university students (n = 1,214) completed an online questionnaire during the COVID-19 pandemic, March 2020-June 2021. We conducted a computer-assisted content analysis of an open-ended question about the perceived changes that occurred to them during the pandemic.

RESULTS

(1) Four thematic clusters were identified: "The psychological impact of the pandemic," "New ties and new loneliness," "An uncertain forethought" and "Discovering the value of relationships." (2) In subjects characterized by severe SI, the state of confinement at home was related to the most intense emotional states and worries. (3) Students with severe SI were different from the others, in particular using the lemma "panic," which was the only psychological state specifically associated with this group.

CONCLUSIONS

Students with current severe SI experienced higher level of psychological distress and suffering compared to the other groups during the pandemic.

Dietary supplementation with Lactium and L-theanine alleviates sleep disturbance in adults: a double-blind, randomized, placebo-controlled clinical study

Introduction

The use of natural products for the treatment of sleep disturbances is increasing owing to the side effects and limitations of traditional sleep therapy. Moreover, recent studies have shown a significant correlation between sleep quality and gut microbiota composition. This study aimed to assess the impact of LTC-022, a commercially available dietary supplement containing Lactium and L-theanine, on enhancing sleep quality.

Methods

Forty participants experiencing sleep discomfort were enrolled in a double-blind randomized controlled trial, wherein they received LTC-022 or a placebo orally for 8 weeks. The effects of treatment on sleep quality were assessed using the Pittsburgh Sleep Quality Index and Insomnia Severity Index. To comprehensively evaluate changes in sleep patterns, various parameters were evaluated, including the time in bed (TIB), total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), wake after sleep onset (WASO) counts, and bedtime. These parameters were derived from daily sleep logs recorded over the 8-week study period, categorized into weekdays and weekends. Stool samples were analyzed for microbiome composition. The V4 region of bacterial 16S rRNA genes was amplified using specific primers (515F and 806R) and targeted for analysis. Microbial diversity, including operational taxonomic units, the Shannon and Chao indices, the Firmicutes/Bacteroidetes (F/B) ratio, and the variety of bacterial taxa, was assessed.

Results

No significant differences were observed in sleep quality and insomnia scale characteristics between the two groups. In-depth analysis using sleep diaries showed that WASO counts after 8 weeks and bedtime after 4 weeks showed significant differences between the LTC-022 and control groups. In the LTC-022 group, significant differences were observed in the increase in TST, decrease in SOL, increase in SE, decrease in WASO counts, and earlier bedtime. Microbiome analysis revealed that the abundance of the genera Blautia and Ruminococcus increased in fecal samples from the LTC-022 group.

Conclusion

These results suggest that continuous LTC-022 intake has a beneficial effect on maintaining sleep duration and an appropriate bedtime. Additionally, changes in the gut microbiota may be linked to changes in sleep patterns resulting from the consumption of Lactium and L-theanine.

Prevalence of mental health symptoms and associated risk factors among healthcare workers in specialized COVID-19 hospitals in Anyang, China: A cross-sectional survey

Background

The novel coronavirus disease 2019 (COVID-19) pandemic spread worldwide and brought unprecedented challenges to healthcare systems. Healthcare workers experienced tremendous pressure and psychological issues.

Methods

A cross-sectional online survey was conducted from January 2022 to April 2022 among healthcare workers in Anyang, Henan Province, China. Insomnia, anxiety, depression, post-traumatic stress disorder (PTSD), and problematic internet use (PIU) were evaluated. Logistic regression analyses were used to explore the factors that were associated with mental health problems.

Results

A total of 242 participants (mean [SD] age, 34.7 [6.6] years, 187 female [77.3 %]) were included in the study. The prevalence of symptoms of insomnia, anxiety, depression, PTSD and PIU during the COVID-19 pandemic in China was 53.7 %, 100.0 %, 7.0 %, 20.3 %, and 19.4 %, respectively. Participants who smoked, used sedative-hypnotic drugs and may need psychological assistance were at a higher risk for mental health problems. Respondents who were older than 45 years and were married displayed a lower risk of insomnia and PTSD, respectively.

Conclusions

Mental health symptoms are pervasive among healthcare workers in specialized COVID-19 hospitals during the outbreak. Risk factors include smoking, sedative-hypnotic drug use, and the need for psychological assistance, while protective factors include age and marital status. Developing social media platforms and providing psychological assistance may be effective interventions for healthcare workers.

Global prevalence of anxiety and depression among medical students during the COVID-19 pandemic: a systematic review and meta-analysis

PURPOSE

As future physicians, medical students have experienced tremendous pressure during the ongoing COVID-19 pandemic, which is associated with a high risk of depression and anxiety. We aimed to investigate an overview of the prevalence of anxiety and depression among medical students in various countries during the global COVID-19 pandemic, and discuss associated stressors.

METHODS

We systematically searched CINAHL, EMBASE, MEDLINE, PubMed, and Web of Science for relevant articles from December 1, 2019 to March 15, 2023. We performed meta-analysis using a random-effects model with REML method to calculate the pooled prevalence of anxiety and depression. Begg's and Egger's tests were used to identify the potential risk of publication bias. Meta-regression was used to explore potential sources of heterogeneity.

RESULTS

We identified 130 studies reporting anxiety and depression among 132,068 medical students during the COVID-19 pandemic. Eight screening tools were identified for anxiety and six for depression. The pooled prevalence of mental health outcomes for anxiety and depression was 45% (95% confidence interval [CI], 40%-49%) and 48% (95% CI, 43%-52%), respectively. The pooled prevalence of mental health outcomes for moderate and severe anxiety and moderate and severe depression was 28% (95% CI, 24%-32%) and 30% (95% CI, 26%-35%), respectively. There was high heterogeneity between studies, with I2 ranging from 99.58%-99.66%. Continent and survey date were included in the meta-regression model. The results of meta-regression revealed that medical students in Asia had a lower prevalence of anxiety, and depression than those in other regions. The survey date (from February to June, 2020) showed a significantly positive correlation with the prevalence of anxiety and depression.

CONCLUSIONS

We demonstrated the global prevalence of anxiety and depression among medical students during the COVID-19 pandemic. The data highlight that medical students worldwide are at high risk of experiencing anxiety and depression. The reported stressors can be categorized into personal, academic, environmental and cultural, and pandemic factors. Schools and institutions should ensure optimal alternative learning environments for uninterrupted provision of medical education. The appropriate authorities should prioritize the provision of adequate protection for medical students and establish policies to promote new methods of training and education during a disaster, such as via distance learning.

Depressive Symptoms Among Higher Education Students in Germany-A Systematic Review and Meta-Analysis

Objectives

Higher education students in Germany are vulnerable to depressive symptoms. Despite ample evidence, no comprehensive review has recently been conducted. Thus, our systematic review and meta-analysis aims at describing the extent to which students are affected by depressive symptoms.

Methods

We searched three databases for articles reporting the prevalence rates of depressiveness among students in Germany published between 2002 and 2023. Pooled prevalence rates were calculated using random effects models, both for the overall sample and for subgroups categorized by gender, study setting, assessment instrument, and whether the study was conducted before or during the COVID-19 pandemic.

Results

The search yielded 992 records. After screening, 60 articles remained for data extraction. About one out of five students (21.1%) exhibits depressive symptoms. Pooled prevalence rates differ between subgroups, with higher rates during the COVID-19 pandemic than before (30.6% versus 18.0%) and with females being more affected than their male counterparts (29.0% versus 23.1%).

Conclusion

This review underlines the urgency with which the mental health of students should be addressed at the (higher educational) policy level.

Association between pretreatment emotional distress and immune checkpoint inhibitor response in non-small-cell lung cancer

Emotional distress (ED), commonly characterized by symptoms of depression and/or anxiety, is prevalent in patients with cancer. Preclinical studies suggest that ED can impair antitumor immune responses, but few clinical studies have explored its relationship with response to immune checkpoint inhibitors (ICIs). Here we report results from cohort 1 of the prospective observational STRESS-LUNG study, which investigated the association between ED and clinical efficacy of first-line treatment of ICIs in patients with advanced non-small-cell lung cancer. ED was assessed by Patient Health Questionnaire-9 and Generalized Anxiety Disorder 7-item scale. The study included 227 patients with 111 (48.9%) exhibiting ED who presented depression (Patient Health Questionnaire-9 score ≥5) and/or anxiety (Generalized Anxiety Disorder 7-item score ≥5) symptoms at baseline. On the primary endpoint analysis, patients with baseline ED exhibited a significantly shorter median progression-free survival compared with those without ED (7.9 months versus 15.5 months, hazard ratio 1.73, 95% confidence interval 1.23 to 2.43, P = 0.002). On the secondary endpoint analysis, ED was associated with lower objective response rate (46.8% versus 62.1%, odds ratio 0.54, P = 0.022), reduced 2-year overall survival rate of 46.5% versus 64.9% (hazard ratio for death 1.82, 95% confidence interval 1.12 to 2.97, P = 0.016) and detriments in quality of life. The exploratory analysis indicated that the ED group showed elevated blood cortisol levels, which was associated with adverse survival outcomes. This study suggests that there is an association between ED and worse clinical outcomes in patients with advanced non-small-cell lung cancer treated with ICIs, highlighting the potential significance of addressing ED in cancer management.

Dexmedetomidine Inhibits Paraventricular Corticotropin-releasing Hormone Neurons that Attenuate Acute Stress-induced Anxiety-like Behavior in Mice

BACKGROUND

Dexmedetomidine has repeatedly shown to improve anxiety, but the precise neural mechanisms underlying this effect remain incompletely understood. This study aims to explore the role of corticotropin-releasing hormone-producing hypothalamic paraventricular nucleus (CRHPVN) neurons in mediating the anxiolytic effects of dexmedetomidine.

METHODS

A social defeat stress mouse model was used to evaluate the anxiolytic effects induced by dexmedetomidine through the elevated plus maze, open-field test, and measurement of serum stress hormone levels. In vivo Ca2+ signal fiber photometry and ex vivo patch-clamp recordings were used to determine the excitability of CRHPVN neurons and investigate the specific mechanism involved. CRHPVN neuron modulation was achieved through chemogenetic activation or inhibition.

RESULTS

Compared with saline, dexmedetomidine (40 µg/kg) alleviated anxiety-like behaviors. Additionally, dexmedetomidine reduced CRHPVN neuronal excitability. Chemogenetic activation of CRHPVN neurons decreased the time spent in the open arms of the elevated plus maze and in the central area of the open-field test. Conversely, chemogenetic inhibition of CRHPVN neurons had the opposite effect. Moreover, the suppressive impact of dexmedetomidine on CRHPVN neurons was attenuated by the α2-receptor antagonist yohimbine.

CONCLUSIONS

The results indicate that the anxiety-like effects of dexmedetomidine are mediated via α2-adrenergic receptor-triggered inhibition of CRHPVN neuronal excitability in the hypothalamus.

EDITOR’S PERSPECTIVE

Positive Orientation and Feelings of Loneliness among Polish Students during the COVID-19 Pandemic

Background/Objectives: The COVID-19 pandemic was a time of limited direct contact with other people. The aim of this study was to determine the role of positive orientation and sociodemographic variables in the feelings of global, social and emotional loneliness and to seek predictors for loneliness among students during the COVID-19 pandemic. Methods: The study was conducted on a group of 798 students at the University of Warmia and Mazury in Olsztyn (Poland) between January and March 2022. The empirical data were gathered with the following research tools: the Positive Orientation Scale and the De Jong Gierveld Loneliness Scale-DJGLS. Results: The study found a correlation (r = -0.370; p < 0.001) between positive orientation and emotional loneliness. The level of loneliness was significantly higher in students who greatly reduced their social contact, compared to those who reduced them moderately (p < 0.001). The intensity of social loneliness among women was lower (p < 0.001) than among men. Those who lived with their families or with a close companion felt less intense emotional loneliness (p < 0.001) than those who lived alone. Conclusions: A positive orientation, which manifests itself in a favourable opinion about oneself and in attaching weight to positive aspects of life, was found to be the main determinant of the feelings of global and emotional loneliness. However, it did not prove to be a predictor of social loneliness in the group of students under study.

Assessment of educational technology in lactation physiology by health students

OBJECTIVES

to assess the suitability, facilitators, and barriers of using a video clip for teaching lactation physiology to health students.

METHODS

a cross-sectional study was conducted with online data collection at a higher education institution, using the Assistive Technology Assessment Instrument and open-ended questions. The sample consisted of 88 students.

RESULTS

the video clip was deemed suitable in all attributes. Facilitators identified included attractiveness, musicality, and ease of access. Barriers noted were the music's speed and the necessity for prior knowledge. The video clip achieved adequate scores for interactivity (1.71), purpose (1.77), relevance (1.64), and clarity (1.77). The overall average of the attributes was 1.72.

CONCLUSIONS

the video clip can serve as an effective learning strategy to enhance hybrid education, potentially contributing to the promotion and support of breastfeeding. However, some barriers underscore the importance of prior knowledge for a complete understanding of the content.

Depressive symptoms and all-cause mortality among middle-aged and older people in China and associations with chronic diseases

Introduction

It remains unclear whether depressive symptoms are associated with increased all-cause mortality and to what extent depressive symptoms are associated with chronic disease and all-cause mortality. The study aims to explore the relationship between depressive symptoms and all-cause mortality, and how depressive symptoms may, in turn, affect all-cause mortality among Chinese middle-aged and older people through chronic diseases.

Methods

Data were collected from the China Health and Retirement Longitudinal Study (CHARLS). This cohort study involved 13,855 individuals from Wave 1 (2011) to Wave 6 (2020) of the CHARLS, which is a nationally representative survey that collects information from Chinese residents ages 45 and older to explore intrinsic mechanisms between depressive symptoms and all-cause mortality. The Center for Epidemiological Studies Depression Scale (CES-D-10) was validated through the CHARLS. Covariates included socioeconomic variables, living habits, and self-reported history of chronic diseases. Kaplan-Meier curves depicted mortality rates by depressive symptom levels, with Cox proportional hazards regression models estimating the hazard ratios (HRs) of all-cause mortality.

Results

Out of the total 13,855 participants included, the median (Q1, Q3) age was 58.00 (51.00, 63.00) years. Adjusted for all covariates, middle-aged and older adults with depressive symptoms had a higher all-cause mortality rate (HR = 1.20 [95% CI, 1.09-1.33]). An increased rate was observed for 55-64 years old (HR = 1.23 [95% CI, 1.03-1.47]) and more than 65 years old (HR = 1.32 [95% CI, 1.18-1.49]), agricultural Hukou (HR = 1.44, [95% CI, 1.30-1.59]), and nonagricultural workload (HR = 1.81 [95% CI, 1.61-2.03]). Depressive symptoms increased the risks of all-cause mortality among patients with hypertension (HR = 1.19 [95% CI, 1.00-1.40]), diabetes (HR = 1.41[95% CI, 1.02-1.95]), and arthritis (HR = 1.29 [95% CI, 1.09-1.51]).

Conclusion

Depressive symptoms raise all-cause mortality risk, particularly in those aged 55 and above, rural household registration (agricultural Hukou), nonagricultural workers, and middle-aged and older people with hypertension, diabetes, and arthritis. Our findings through the longitudinal data collected in this study offer valuable insights for interventions targeting depression, such as early detection, integrated chronic disease care management, and healthy lifestyles; and community support for depressive symptoms may help to reduce mortality in middle-aged and older people.
