Temporary employment and suicidal ideation in COVID-19 pandemic in Japan: A cross-sectional nationwide survey

The association of positive emotions with absenteeism and presenteeism in Japanese workers

BACKGROUND

Negative emotions such as depression have been associated with increased absenteeism and presenteeism, contributing to substantial economic loss. However, no study has investigated if positive emotions such as happiness influence absenteeism and presenteeism.

METHODS

Using data from the Japan COVID-19 and Society Internet Survey (JACSIS), a nationwide survey conducted in September-October 2022 (n = 19,214), we investigated if two major, representative positive emotions (happiness and gratitude) are associated with absenteeism and presenteeism. Absenteeism was defined as reporting more than one day of sick leave in the past one month. Presenteeism was measured with the Work Functioning Impairment Scale. Logistic regression was used to estimate odds ratios.

RESULTS

12.4 % and 21.8 % of subjects reported absenteeism and presenteeism, respectively. Logistic regression estimated that after adjusting covariates, happiness was associated with lower odds of absenteeism (OR = 0.792, 95 % CI [0.706, 0.888]) and presenteeism (OR = 0.531, 95 % CI [0.479, 0.588]) while gratitude was associated with lower odds of presenteeism only (OR = 0.705, 95 % CI [0.643, 0.774]). Furthermore, simultaneous presence of both happiness and gratitude was associated with further lower odds of presenteeism (OR = 0.385, 95%CI [0.338, 0.439]), indicating a synergetic relation.

DISCUSSION

This study is the first to investigate the association between positive emotions and absenteeism and presenteeism. Given the substantial economic loss due to absenteeism and presenteeism, strategies to enhance positive emotions are necessary.

Is a change in economic status associated with anxiety, depression and suicide ideation during the COVID-19 pandemic in South Korean adults?

BACKGROUND

Coronavirus disease 2019 (COVID-19) affected global economic changes and mental health outcomes. However, sex differences are unclear regarding the relationship between economic status change and mental health outcomes during the pandemic. Therefore, we investigated whether change in economic status is associated with depression, anxiety and suicidal ideation, based on sex.

METHODS

We used data from the COVID-19 National Mental Health Survey 2021 in South Korea. We used the Generalized Anxiety Disorder (GAD) 7-item scale for measuring anxiety, the Patient Health Questionnaire-9 scale for measuring depression and self-reported questionnaires for investigating suicidal ideation and COVID-19-related suicidal ideation.

RESULTS

Among 2000 participants, those with a worse economic status change had a 2.7-fold higher risk of GAD (prevalence ratio [PR], 2.70; 95% confidence interval [CI], 2.07-3.51); 2.5-fold higher depression risk (PR, 2.55; 95%CI, 2.05-3.18); 2.1-fold higher risk of suicidal ideation (PR, 2.09; 95%CI, 1.72-2.53); and 4.0-fold higher risk of COVID-19-related suicidal ideation (PR, 4.03; 95%CI, 2.78-5.83). Women whose economic status worsened had a 3.5-fold higher risk of COVID-19-related suicidal ideation (PR, 3.49; 95%CI, 2.01-6.06).

CONCLUSION

Worse economic change is associated with negative mental health outcomes during the COVID-19 pandemic; particularly, women experiencing financial hardships during the pandemic had a higher risk of COVID-19-related suicidal ideation.

Prevalence of suicidal ideation and correlated risk factors during the COVID-19 pandemic: A meta-analysis of 113 studies from 31 countries

The purpose of this study was to estimate the prevalence of suicidal ideation and correlated risk factors during the COVID-19 pandemic. Web of Science (WOS) and PubMed were searched according to a pre-set strategy. A total of 132 studies were identified, 104 of which were included in the meta-analysis. The prevalence of suicidal ideation was approximately 14.7% (95%CI: 12.5%, 16.8%, P < 0.01) in the general population, approximately 22.4% (95%CI: 17.1%, 27.8%, P < 0.01）in adolescents, approximately 21.0% (95%CI: 12.8%, 29.2%, P < 0.01) in psychiatric patients, approximately 20.6% (95%CI: 18.7%, 22.5%, P < 0.01）in university students, approximately 18.9% (95%CI: 8.3%, 29.5%, P < 0.01) in younger adults, approximately 10.6% (95%CI: 1.0%, 20.2%, P = 0.031) in COVID-19 patients and approximately 7.4% (95%CI: 4.3%, 10.5%, P < 0.01) in healthcare workers. The prevalence in North America was approximately 16.0% (95%CI: 13.6%-18.4%, P < 0.001), approximately 14.5% in Asia (95%CI: 9.5%-19.4%, P < 0.001), approximately 10.5% in Europe (95%CI: 8.5%-12.4%, P < 0.001), and approximately 20.5% in South America (95%CI: 19.5%-21.5%, P < 0.001). The following were risk factors which might be correlated with suicidal ideation: severe anxiety symptoms, mild to moderate depression, a strong feeling of loneliness/social isolation, poor sleep quality, having COVID-19-related experience, having quarantine or lockdown experience, being female, being single or divorced, having financial problems and having a history of suicidal ideation/attempt. This article reports the prevalence of suicidal ideation and discussing potential risk factors during the pandemic among general population and vulnerable groups. Early detection and follow-up were necessary for the noteworthy population.

Relationship between self-esteem and suicidal ideation before and during COVID-19 in a non-clinical sample: mediating effects of psychological distress and hopelessness

Introduction

Several studies have highlighted the impact of the novel coronavirus disease (COVID-19) pandemic on suicide. Accordingly, investigating the risk factors of suicide during this crisis is important. Based on the escape theory of suicide, the current study examined the serial mediating roles of psychological distress and hopelessness in the relationship between self-esteem and suicidal ideation. It also aimed to explore whether or not the COVID-19 pandemic changed the mediation effect in any way.

Methods

Data were collected from 645 university students before and during the pandemic. The study employed mediation and multi-group analyses to test the hypotheses.

Results

The results demonstrated that individuals with low self-esteem reported high psychological distress, which further lead to hopelessness and eventually heightened suicidal ideation. Multi-group analysis revealed that psychological distress exerted a greater impact on suicidal ideation during COVID-19.

Discussion

The finding suggested that self-esteem, hopelessness, and psychological distress could help elucidate the development of suicidal ideation. Clinicians may target these factors in suicide prevention programs, particularly in the settings of the COVID-19 pandemic or future crisis.

Investigating the potential association of temporary employment and job dissatisfaction with alcohol use disorder and depressive symptoms: a 13-wave longitudinal analysis

BACKGROUND

There has been growing interest in protecting workers' mental health. Identifying social determinants that affect workers' mental health could play an important role in preventing psychiatric diseases.

AIMS

We investigated the effects of temporary employment and job dissatisfaction on alcohol use disorder and depressive symptoms.

METHOD

The Korea Welfare Panel Study data-set (2009-2021) was used, and 9611 participants with 52 639 observations were included. Generalised linear mixed models were employed to estimate odds ratios and 95% confidence intervals. The relative excess risk due to interaction (RERI) was calculated to assess supra-additive interactions between temporary employment and job dissatisfaction.

RESULTS

Increased risks for depressive symptoms were observed among fixed-term workers (odds ratio 1.12, 95% CI 1.00-1.26) and daily labourers (odds ratio 1.68, 95% CI 1.44-1.95). Daily labourers were associated with an increased risk of alcohol use disorder (odds ratio 1.54, 95% CI 1.22-1.95). Job dissatisfaction was associated with alcohol use disorder (odds ratio 1.78, 95% CI 1.52-2.08) and depressive symptoms (odds ratio 4.88, 95% CI 4.36-5.46). This effect became stronger when workers were concurrently exposed to temporary employment and job dissatisfaction. Daily labourers with job dissatisfaction showed the highest risks for alcohol use disorder (odds ratio 2.99, 95% CI 2.21-4.03) and depressive symptoms (odds ratio 9.00, 95% CI 7.36-11.02). RERIs between daily employment and job dissatisfaction were >0 for alcohol use disorder (0.91, 95% CI 0.06-1.76) and depressive symptoms (3.47, 95% CI 1.80-5.14), indicating a supra-additive interaction.

CONCLUSIONS

We revealed that temporary employment and job dissatisfaction had detrimental effects on alcohol use disorder and depressive symptoms.

Suicide and COVID-19: a rapid scoping review

There is considerable interest in exploring effects of coronavirus disease 2019 (COVID-19) pandemic on mental health. Suicide is one of the leading causes of mortality worldwide and changes in daily life brought by the pandemic may be additional risk factors in people with pre-existing mental disorders. This rapid PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) scoping review aims to identify and analyze current evidence about the relation between COVID-19 pandemic outbreak, along with COVID-19 disease and severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection, and suicide in individuals with previously diagnosed mental disorders. First, we conducted a comprehensive review of the literature, then proceeded to discuss findings in a narrative way. Tables were constructed and articles sorted according to the studies' methodologies. 53 papers were eventually identified as eligible, among which 33 are cross-sectional studies, 9 are longitudinal studies, and 11 studies using other methodologies. Despite suffering from a mental disorder is a risk factor for suicidal behavior per se, the advent of COVID-19 pandemic may exacerbate this relation. Nevertheless, data addressing a clear correlation between suicidal behavior and the pandemic outbreak are still controversial. Longitudinal analysis using validated suicide scales and multicenter studies could provide deeper insight and knowledge about this topic.

Verification of Psychophysiological Effects of Satoyama Activities on Older Adult Volunteers and Young People in Post-COVID-19 Society: A Case Study of Matsudo City, Japan

Many scholars have focused on Satoyama, which is characterized by mountains or villages away from the urban spaces. Our objective is to verify its psychophysiological effects on people performing usual Satoyama activities in ignored, small urban green spaces to help people find ways to stay healthy in post-coronavirus disease 2019 (COVID-19) society. In this study, 12 older adult volunteers from the "Forest around the Mountains" Nonprofit Organization and 12 young people from the university were invited as study subjects. They were asked to observe nature for 10 min and work for 30 min in the small green space "Forest around the Mountains". The Profile of Mood States 2nd Edition (POMS) and the State-Trait Anxiety Inventor (STAI) were used as psychological scales to detect their psychological restoration and blood pressure before and after the Satoyama activity. Their heart rate during the activity was used as the physiological indicator. The study showed that, as Satoyama volunteers, the older adults group had significant restorative psychophysiological effects during this experiment compared to the younger group; their systolic and diastolic blood pressure dropped significantly after Satoyama activities, On the other hand, the young group have been in the normotensive range before or after Satoyama activities The psychological indicators such as Anger-hostility, Confusion-bewilderment, and Tension-anxiety were significantly lower in the younger group but were still significantly higher than the indicators of the older adults. In general, this study found that Satoyama activities benefited young and older participants, especially older adults with high blood pressure. Satoyama activities in small urban green spaces are thus necessary and worth promoting in the post-COVID-19 era.

Impact of the COVID-19 pandemic on suicide rates in Japan through December 2021: An interrupted time series analysis

BACKGROUND

The COVID-19 pandemic is negatively impacting mental health globally. While increased social cohesion may have initially decreased suicide risk, there are few reports on the long-term impact. We examined the impact of the pandemic on suicide by gender and age through December 2021 in Japan.

METHODS

We analyzed trends in monthly suicide rates by age and gender from January 2016 to December 2021 using provisional mortality data in an interrupted time series analysis. We also considered linear trends in the pre-pandemic period and seasonal variations. Pandemic onset was defined as from April 2020. Estimated excess deaths by suicide that occurred during the pandemic were calculated.

FINDINGS

Excess number of suicide deaths during the pandemic period was estimated to be 1208 for men and 1825 for women. While there was no statistically significant increase in suicide rates overall for both men and women during the pandemic compared to the pre-pandemic, age-specific analyses showed a statistically significant increase in men 20-29 and 40-49 years, and in women of all age groups, except those under 20, 40-49 and over 80 years.

INTERPRETATION

The COVID-19 pandemic has had a negative impact on suicide rates in Japan and the impact is most pronounced in women and younger age groups. Subgroup analyses are needed, with a particular focus on those considered to be vulnerable and at increased suicide risk.
