Relationships between Occupational Stress, Change in Work Environment during the COVID-19 Pandemic, and Depressive and Anxiety Symptoms among Non-Healthcare Workers in Japan: A Cross-Sectional Study

An in-person survey of the influence of the COVID-19 pandemic on physical function, functional capacity, cognitive function, and mental health among community-dwelling older adults in Japan from 2016 to 2022

BACKGROUND

The COVID-19 outbreak might have had several effects on older adults; however, much of the previous research only included self-report, cross-sectional, and online-survey data in the early stage of the pandemic. We conducted a face-to-face survey before and after the COVID-19 pandemic and investigated the influence of the pandemic on several functions to distinguish between changes due to aging and changes due to the pandemic using a linear mixed model.

METHODS

A total of 8 longitudinal surveys were conducted from 2016 to 2022. Physical function was assessed by weight, body mass index, body fat percentage, skeletal muscle mass index, calf circumference, grip strength, knee extension strength, the 5-times chair stand test, the timed up & go test and 5-m walking test. Functional capacity was measured using the Tokyo Metropolitan Institute of Gerontology index of competence, cognitive function was measured using the Trail Making Test - A, and mental health was measured using the Geriatric Depression Scale.

RESULTS

Of a total of 73 participants, 51 (69.9%) were female. The mean age at first participation was 71.82 years (SD = 4.64). The results of the linear mixed model showed that lower-limb muscle strength and body fat percentage and cognitive function changed significantly before and after the pandemic, while grip strength, functional capacity, and mental health did not.

CONCLUSIONS

The changes in these functions between before and after the pandemic might be attributed to the diminished opportunities for the independent older individuals to go out and engage in activities. Although functional capacity did not change, lower-limb muscle strength is important for functional independence. This decline might influence the functional capacity of these individuals in the future.

Factors associated with cognitive impairment and the quality-of-life among COVID-19 survivors working as healthcare workers

Prolonged physical and mental health changes, known as post-COVID conditions (PCC), could impair the quality-of-life (QoL) of healthcare workers. The aim of this study was to identify factors that contribute to cognitive impairments and QoL among COVID-19 survivors working as healthcare workers. This cross-sectional study involved healthcare workers at Prof. Dr. Chairuddin P. Lubis Universitas Sumatera Utara Hospital, Medan, Indonesia. The Montreal Cognitive Assessment (MoCA) was used to assess the cognitive function, while the World Health Organization Quality-of-Life Brief Version (WHOQOL-BREF) questionnaire was used to evaluate the QoL. Factors associated with cognitive and QoL status were examined using Mann-Whitney and Chi-squared tests. A total of 100 COVID-19 survivors were included in the study, most of whom were female (74%), aged ≤35 years (95%), and were doctors (62%). Only 22% of the participants had a normal BMI, 93% had a history of mild COVID-19, and 54% had one comorbidity. The Overall MoCA score averaged 24.18±2.86, indicating mild cognitive impairment among the groups. The distribution of MoCA scores had similar patterns with no significant differences based on age, gender, comorbidities, BMI, COVID-19 severity, and frequency of COVID-19 infection. Interestingly, the number of vaccine doses received by the participants had a statistically significant associated with MoCA scores of which those receiving more than two doses had higher cognitive scores than those with only two doses (p=0.008). Based on categorized MoCA scores (normal vs cognitive impairment), none assessed factors were not significantly associated with cognitive outcomes. The WHOQOL-BREF scores ranged from 62.5 to 95.5, with a mean±SD of 83.67±7.03. None of the assessed factors were associated with WHOQOL-BREF scores among COVID-19 survivors. These findings highlight the need for further study to explore the protective role of vaccination frequency in cognitive impairment and the factors underlying the resilience in QoL among survivors.

Effect of COVID-19 Risk Perception and COVID-19 Self-Care of Korean Correctional Nurses on Occupational Burnout: Mediating Effect of Stress and Anxiety About Viral Epidemics

ABSTRACT

The purpose of this study was to investigate whether stress and anxiety about viral epidemics have effects as parameters in the relationship among COVID-19 risk perception, COVID-19 self-care, and occupational burnout for Korean correctional nurses. The subjects of this study were 107 correctional nurses working at 52 correctional facilities in Korea that are conducting COVID-19 management and prevention activities. Data were collected from March 12 to 30, 2022. Results suggest that correctional nurses during the COVID-19 pandemic may experience occupational burnout because of increased stress and anxiety about viral epidemics as their COVID-19 risk perception increased. In addition, stress and anxiety about being infected with the COVID-19 virus itself will cause burnout. This study contributes to promotion of the mental health of Korean correctional nurses and provides basic data for developing an intervention program to prevent occupational burnout.

Assessment of the anxiolytic, antidepressant, and antioxidant potential of Parquetina nigrescens (Afzel.) Bullock in Wistar rats

ETHNOPHARMACOLOGICAL RELEVANCE

The recent growing concerns about the multisystemic nature of mental health conditions in the global population are facilitating a new paradigm involving alternative natural, nutritional, and complementary therapies. Herbal remedies despite accounts in literature of their ethnobotanical as alternative remedies for diverse ailments, remain underexplored for psychiatric disorders like anxiety, depression, and insomnia.

AIM OF THE STUDY

Hence, the anxiolytic, antidepressant, and antioxidant properties of a hydro-ethanolic leaf extract of Parquetina nigrescens (PN) in male Wistar rats were investigated.

MATERIALS AND METHODS

The sedative effect was evaluated using the Diazepam sleeping time test while anxiety was induced with a single intraperitoneal injection of 20 mg/kg pentylenetetrazol (PTZ). This was after pre-treatment with 100, 150, and 250 mg/kg of PN or the standard drugs (1 mg/kg diazepam and 30 mg/kg imipramine) for 14 consecutive days. Behavioral tests (Open Field test, Elevated Plus-Maze test, and Forced Swim test) were performed on days 1 and 14, to evaluate the antidepressant and anxiolytic activities of PN. Oxidative stress and neurochemical markers were determined in the brain homogenates of the animals.

RESULTS

The duration of sleep was significantly (p < 0.001) increased in the PN-administered group compared to the control. The behavioral models showed that PN exhibited antidepressant and anxiolytic properties in PTZ-induced animals. Significant reductions were observed in GSH level and SOD activity while MDA, nitrite, and GPx levels were significantly increased in PTZ-induced rats. However, treatment with PN significantly improved brain antioxidant status by ameliorating the PTZ-induced oxidative stress. Dopamine, cortisol, and acetylcholine esterase activity levels were significantly (p < 0.05) elevated while serotonin and brain-derived neurotrophic factors were reduced in PTZ-induced rats compared with the control.

CONCLUSION

The PN demonstrated neurotransmitter modulatory ability by ameliorating the PTZ-induced neurochemical dysfunction. Findings from this study showed that PN exhibited sedative, antidepressant, and anxiolytic activities in rats.

Predictors of anxiety and depression in operating room nurses during the COVID-19 pandemic: A multi-center cross-sectional study

BACKGROUND

Operating room nurses (ORNs) who directly deal with the treatment and care of COVID-19 patients during the pandemic are at risk in terms of psychological stress and other mental health problems.

OBJECTIVE

The aim of the study was to compare the anxiety and depression levels of ORNs working in different countries in the COVID-19 outbreak, and to determine the predictors and the difference between countries.

METHODS

This was a descriptive and cross-sectional study. Data were collected online using a google form between February 2021-February 2022. The universe of the research is nurses who are members of national Perioperative Nurses Association (USA, Türkiye, Australia, England, India, Israel) and 1127 ORNs participated the study. In multivariate analysis, independent predictors of anxiety and depression status were examined by binary logistic regression analysis.

RESULTS

The rate of anxiety is 5.46 times higher in nurses in the USA, 5.07 times higher among nurses in Australia, and 4.49 times higher for nurses in England. It was determined that the rate of depression in ORNs working in Türkiye was 5.97 times higher. It was found that the rate of depression is 1.59 times higher in ORNs living away from the family after care of COVID-19 patient.

CONCLUSION

Despite some differences between countries in terms of health system, patient potential, economic and the opportunities offered, generally high levels of anxiety and/or depression indicate that all ORNs need urgent support. Identifying risk factors will help recognize anxiety and depression in ORNs and take measures to protect their mental health during the pandemic.

Anxiety among healthcare workers during the COVID-19 pandemic: a longitudinal study

Background

During the COVID-19 pandemic, many healthcare workers faced extreme working conditions and were at higher risk of infection with the coronavirus. These circumstances may have led to mental health problems, such as anxiety, among healthcare workers. Most studies that examined anxiety among healthcare workers during the COVID-19 pandemic were cross-sectional and focused on the first months of the pandemic only. Therefore, this study aimed to investigate the longitudinal association between working in healthcare and anxiety during a long-term period (i.e., 18 months) of the COVID-19 pandemic.

Methods

Data were used from online questionnaires of the Lifelines COVID-19 prospective cohort with 22 included time-points (March 2020-November 2021). In total, 2,750 healthcare workers and 9,335 non-healthcare workers were included. Anxiety was assessed with questions from the Mini-International Neuropsychiatric Interview, and an anxiety sum score (0-7) was calculated. Negative binomial generalized estimating equations (GEE), adjusted for demographic, work and health covariates, were used to examine the association between working in healthcare and anxiety.

Results

Anxiety sum scores over time during the COVID-19 pandemic were similar for healthcare workers and non-healthcare workers. No differences between the anxiety sum scores of healthcare workers and non-healthcare workers were found [incidence rate ratio (IRR) = 0.97, 95% CI = 0.91-1.04].

Conclusion

This study did not find differences between healthcare workers and non-healthcare in perceived anxiety during the COVID-19 pandemic.

Change of human flourishing during the COVID-19 pandemic in Japan: Results from population-based U-CORONA study

Longitudinal change in flourishing during the pandemic of COVID-19 would provide new insight to reveal determinants of well-being. We aimed to describe changes in flourishing during the COVID-19 pandemic in Japan and to examine the association of sex, age, education, and income with changes in flourishing. Utsunomiya COVID-19 seROprevalence Neighborhood Association (U-CORONA) study conducted in October 2020 and November 2021 was used (n = 419 in 2020 and n = 478 in 2021, and n = 327 for both waves). Flourishing was assessed using a 12-item multidimensional flourishing scale including six domains. Change of flourishing was categorized into decreased, unchanged, and increased. Multinomial logistic regression was applied to longitudinal data to estimate the relative risk ratio of increase and decrease in flourishing scores. Cross-sectional analysis showed that the mean score of flourishing was approximately seven in both waves, with no sex differences, but older adults had higher scores than young-aged adults. We found that men were twice as likely to lose their flourishing scores as women and lower levels of education were associated with 2-3 times declining flourishing scores than higher levels of education. Age and income were not significantly associated with the change of flourishing. During the COVID-19 pandemic, flourishing declined, and men and lower-educated people were more vulnerable. In prolonged difficult situations, support for men and less educated people may contribute to the prevention of declining well-being in Japan.

Symptoms and risk factors of depression and PTSD in the prolonged COVID-19 pandemic: a longitudinal survey conducted from 2020 to 2022 in Japan

BACKGROUND

The present study aimed to explore changes in depression and posttraumatic stress disorder (PTSD) among the general population during the prolonged COVID-19 pandemic and to investigate risk factors and adaptive/nonadaptive strategies.

METHODS

A web-based longitudinal survey was conducted across five timepoints from 2020 to 2022 in Japan. Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9), PTSD was measured using Impact of Event Scale-Revised (IESR), and coping strategies were measured using Brief Coping Orientation to Problems Experienced (Brief COPE). Higher scores of PHQ-9 and IESR indicate more symptoms and Higher score of Brief COPE indicate that these means of coping are used very frequently.

RESULTS

A total of 1,366 participants (mean age = 52.76, SD = 15.57) were analyzed. Regarding levels of depression, PHQ-9 scores in 2022 were lower than in 2020 and 2021 (all p < 0.01). Regarding levels of PTSD, IESR scores in 2022 were lower than in 2021 among females (p < 0.001). Being younger (β = -0.08 and - 0.13, both p < 0.01) and engaging in self-blame (β = 0.12 and 0.18, both p < 0.01) increased PHQ-9 scores regardless of sex. For males, not working (β = 0.09, p = 0.004) and having suffered an economic impact (β = 0.07, p = 0.003) were risk factors for depressive symptoms, and active coping (β = -0.10, p = 0.005) was associated with decreased depressive symptoms. For females, substance use (β = 0.07, p = 0.032) and behavioral disengagement (β = 0.10, p = 0.006) increased depressive symptoms, and females did not show strategies that decreased the symptoms.

CONCLUSIONS

Levels of depression might have increased in the early stages of the pandemic and decreased in January 2022. Although males need to improve their economic situation to decrease depressive symptoms, adaptive strategies might be difficult to identify due to the prolonged pandemic among both sexes. In addition, the pandemic might be a depressive event but not a traumatic event among the general population, at least in Japan.

Prevalence and factors associated with self-reported anxiety in adults during the COVID-19 pandemic in Argentina, Brazil, Peru, Mexico, and Spain: A cross-sectional Ibero-American study

The present study evaluated the factors associated with the perception of anxiety during the first wave of covid-19 in Ibero-American countries. This cross-sectional study was carried out with 5.845 participants of both sexes, over 18 years of age, and residents of four Latin American countries-Argentina (16.7%), Brazil (34.5%), Mexico (11.1%), and Peru (17.5%), and one European country-Spain (20.1%). Data were collected in 2020, between April 1st and June 30th in Spain and between July 13th and September 26th in the Latin American countries. We used an online questionnaire with sociodemographic, lifestyle, self-reported anxiety, and covid-19 related questions. The chi-square statistical test and Multivariate logistic regressions were performed to analyze the factors associated with self-reported anxiety. The presence of self-reported anxiety was found in 63.8% of the participants during the isolation period. The association occurred mainly in women (OR:1.52; CI: 1.3-1.7), those aged 18 to 29 years (OR: 1.51; CI: 1.2-1.9) and 30 to 49 years (OR: 1.56; CI: 1.3-1.9), residents of Argentina (OR: 1.55 CI: 1.2-1.9), Brazil (OR: 2.38; CI: 2.0-2.8) and Mexico (OR: 1.52; CI: 1.2-1.9), those who gained weight (OR:1.71 CI: 1.5-1.9) or lost weight (OR: 1.40; CI: 1.2-1.6), and those who reported having slept more (OR: 1.56; CI: 1.3-1.8) or less (OR: 2.89; CI: 2.5-3.4). We conclude that the prevalence of self-reported anxiety in Ibero-American countries was high during the period studied, highlighting a higher likelihood of its occurrence in Brazil, in those who began to sleep less and gained weight.

Psychometric properties of the generalized anxiety disorder-7 (GAD-7) in a sample of workers

Objective

To evaluate the psychometric properties of the GAD-7 by obtaining evidence of internal structure (dimensionality, precision and differential functioning of items) and association with external variables.

Methods

A total of 2,219 protocols from three different studies conducted with Puerto Rican employees that administered the GAD-7 were selected for the current study. Item response theory modeling was used to assess internal structure, and linear association with external variables.

Results

The items were adapted to a graduated response model, with high similarity in the discrimination and location parameters, as well as in the precision at the level of the items and in the total score. No violation of local independence and differential item functioning was detected. The association with convergent (work-related rumination) and divergent (work engagement, sex, and age) variables were theoretically consistent.

Conclusion

The GAD-7 is a psychometrically robust tool for detecting individual variability in symptoms of anxiety in workers.

Association between sickness presenteeism and depressive symptoms in Korean workers during the COVID-19 pandemic: A cross-sectional study

BACKGROUND

During the COVID-19 pandemic, Korean workers have reported various types of sickness presenteeism (SP: continuing to attend work during illness). Understanding SP through mental health perspectives will help to make practical strategy for better working conditions. We examined the association between SP and depression among Korean workers during the COVID-19 pandemic in relation with the socioeconomic and lifestyle factors.

METHODS

Data from the 2020 Korean Community Health Survey were used as a representative nationwide sample dataset. We surveyed the experience of depression in the last two weeks from individuals who worked more than a week recently. We investigated the associations between SP and depressive symptoms. Depressive symptoms were scored using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was performed to examine the significance of the associations.

RESULTS

Analysis of the data obtained from 84,514 participants revealed that 1700 (2.2 %) participants reported experiencing depressive symptoms in 2020. Employees with SP showed higher association with depressive symptoms than employers or self-employed individuals (OR = 2.18, 95 % CI: 1.85, 2.56 among employees vs. OR = 1.76, 95 % CI: 1.29, 2.40 among employers or self-employed individuals).

CONCLUSION

SP has become more prominent during the COVID-19 pandemic. A protective strategy against SP among vulnerable workers is necessary for a healthier and safer society.

Assessing the general health, increase in mental and physical workload among administrative staff of the University of Nigeria due to the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has changed the global workloads and general well-being of employees, especially in the university system. The object of this study is to evaluate the mental health and effect of increase in workload on the general well-being of the administrative staff of the University of Nigeria, Nsukka, on the resumption of academic activities after the lockdown due to COVID-19. A total of 73 randomly selected administrative staff were involved in the study. Three sets of instruments, the demographic questionnaire, National Aeronautics and Space Administration-Task Load Index, and General Health Questionnaire, were used to obtain information on the demographic characteristics, workload, and level of mental disorder among the respondents due to COVID-19. The generalized linear regression model, 1-way analysis of variance, independent samples t test, and contingency coefficient were used to analyze the data. The results revealed that high workload is significantly associated with high risk of mental and general health disorders among the respondents. The married, divorced, widowed, older, and females staff with >2 children are the most vulnerable to mental disorder, physical workload, frustration, and general health challenges. The younger staff, those with at most 2 children, and those who are still single experience lower mental and general health disorder and are more resilient. Significant and comprehensive health and administrative support should be provided for the overall well-being of the staff.
