Increased suicidal ideation in the COVID-19 pandemic: an employee cohort in Japan

ABSTRACT:

Objectives

This study investigated the change in suicidal ideation and its risk factors among employees. A longitudinal cohort study was conducted, starting with the baseline online survey in March 2020 (T1), followed by May (T2), and August (T3). The change in suicidal ideation from T2 to T3 and relevant factors associated with suicidal ideation at T3 were examined. Suicidal ideation significantly increased between May and August 2020 among females, younger (under 39 years old), highly educated population, and those without pre-existing mental health conditions. Factors significantly associated with suicidal ideation were younger age, suicidal ideation at T2, and with pre-existing mental health conditions. Loneliness at T2 showed a significant association with suicidal ideation, if adjusting those without pre-existing mental health conditions. National and community support is needed to target people who are likely to be left behind, such as young people and those with pre-existing mental health conditions, in the pandemic.

Method

A longitudinal study was conducted with a cohort of full-time employees, starting with the baseline online survey in March 2020 (time point 1), followed by May (time point 2) and August (time point 3). The change in suicidal ideation from time point 2 to 3, and relevant factors associated with suicidal ideation at time point 3, were examined.

Results

Suicidal ideation significantly increased between time points 2 and 3 among women, younger people (aged <39 years), those who were highly educated and those without pre-existing mental health conditions. Factors significantly associated with suicidal ideation were younger age, suicidal ideation at time point 2 and pre-existing mental health conditions. Loneliness at time point 2 showed a significant association with suicidal ideation when adjusting for those without pre-existing mental health conditions.

Conclusions

National and community support is needed to target people who are likely to be left behind, such as young people, those with pre-existing mental health conditions and those experiencing loneliness, in the COVID-19 pandemic.

Project description:ObjectivesAssociation between employment contract (temporary vs. permanent) and suicidal ideation (persistent suicidal ideation [i.e., with onset before COVID-19] or newly developed under COVID-19 pandemic) was examined using a nationally representative cross-sectional study in Japan.MethodsAn Internet survey was conducted from August to September 2020. The participants' inclusion criteria for this study were as follows: (i) 20-65 years old, (ii) employees (excluding self-employed, students, retired, housewives, and unemployed). The associations of suicidal ideation with the employees' factors were analyzed using the multinomial logistic regression model, adjusting for covariates (sex, age, marital status, education, company size, industries, and a history of psychiatric disease).ResultsOf total 12 249 participants, 72.4% were permanent and 27.6% were temporary employees. The prevalence was 8.5% for persistent suicidal ideation and 3.2% for newly developed suicidal ideation in the COVID-19 pandemic. Temporary employment was significantly associated with persistent suicidal ideation (adjusted odds ratio [aOR] = 1.36 [95% confidence interval, CI: 1.16-1.59]; P < .001), but not associated with newly developed suicidal ideation (aOR = 1.10 [0.85-1.42]; P = .457) after adjusting the covariates. Sensitivity analysis showed temporary employment was significantly associated with persistent suicidal ideation only in women. Newly developed suicidal ideation was significantly higher among participants of a young age, employees in drinking/eating/hotel business industry, and those having a history of psychiatric disease than among the counterparts.ConclusionsWorking on a temporary employment contract was associated with persistent suicidal ideation under conditions of COVID-19 outbreaks in Japan. However, the result showed no significant difference in newly developed suicidal ideation. Further longitudinal study will be needed to examine the risk of being employed on an unstable occupational contract in the prolonged pandemic.

Project description:ObjectivesWe aim to reveal how loneliness relates to suicidal ideation following the onset of the COVID-19 pandemic.DesignCross-sectional online survey.SettingCommunity cohort study in Japan.ParticipantsThe second wave of a large web-based survey, Japan COVID-19 and Society Internet Survey, was conducted in February 2021, and we analysed the data of 6436 men and 5380 women who were aged 20-59 years.Main outcome measuresThe prevalence ratios (PRs) of suicidal ideation due to loneliness, depression, social isolation and decline in income during the pandemic and other sociodemographic and economic information were adjusted in the analysis.Statistical methodsEstimations were conducted by separating a male and female sample. The survey weight (inverse probability weighting) was applied for analyses, and a Poisson regression model was used with all the potential confounders adjected.ResultsOverall, 15.1% of male and 16.3% of female participants were found to have had suicidal ideation during the COVID-19 pandemic. Among them, 23% of male and 20% of female participants experienced suicidal ideation for the first time. The results of the Poisson regression suggested that those who were feeling lonely had higher PRs for suicidal ideation (4.83 for men (95% CI, 3.87 to 6.16) and 6.19 for women (95% CI, 4.77 to 8.45)). The relationship between loneliness and suicidal ideation remained robust even after adjusting for depression, although there were declines in PRs. Additionally, the results showed that those who were lonely, and continued to feel lonely during the pandemic, had the highest PRs of suicidal ideation.ConclusionLoneliness had both direct and indirect effects on suicidal ideation mediated through depression. Those who felt lonelier during the pandemic had the highest risk of suicidal ideation. It is necessary to adopt national measures focused on providing psychological support to people who feel lonely to prevent them from taking their own lives.

Project description:ObjectiveWith significant levels of mental distress reported by populations, globally, the magnitude of suicidal ideation during and beyond the COVID-19 pandemic is a central concern. The goal of this study was to quantify the extent of pandemic-related suicidal ideation in the Canadian population during the first ten months of the pandemic and identify sociodemographic and pandemic-related stressors associated with increased risk of ideation.MethodData were derived from three rounds of a mental health monitoring survey, nationally representative by age, gender, household income, and region, delivered online in May 2020, September 2020, and January 2021. Bivariate analyses were used to quantify the proportion of respondents in Canada reporting suicidal ideation by sociodemographic factors and pandemic-related stressors. Unadjusted and adjusted multivariable logistic regression was used to study the association between suicidal ideation and correlates within four pandemic-related stressor categories (financial, relationship, substance use, COVID-19 exposure).ResultsOf the 7002 respondents, 6.2% (n = 433) reported experiencing suicidal thoughts or feelings as a result of the pandemic within the two weeks prior to taking the survey. In terms of sociodemographic factors, suicidal ideation was more commonly reported among those who were not cisgender, <65 years-old, single, Indigenous, LGBT2Q+, and who experience a pre-existing mental health condition. After adjusting for sociodemographic factors, indicators across all four pandemic-related stressor categories were associated with two or more times the odds of suicidal ideation.ConclusionDisparities in COVID-19 related suicidal ideation have persisted throughout the first year of the pandemic for specific sociodemographic sub-groups and those who have faced stressors related to finances, relationships, increased substance use, and COVID-19 virus exposure. To best address these disparities and to prevent a transition from suicidal ideation to action, appropriate planning, resources, and policies are needed to ensure health and well-being for everyone.
