Objectives: Work-related subjective well-being (SWB) may be negatively affected by early-life adverse experiences, such as school bullying experience. This study aimed to identify the association between work-related SWB and school bullying experiences. Methods: A systematic review was conducted using five electronic databases to search for published observational studies from inception to May 5th, 2022. Eligibility criteria included the original papers in English, which measured school bullying experiences and work-related SWB (eg, satisfaction, engagement). Eight researchers independently conducted screening and a full-text review. We used the Risk of Bias Assessment tool for Non-randomized Studies to assess the certainty of the evidence. Narrative data were summarized. The study has been registered at UMIN-CTR (UMIN000040513). Results: A total of 6,842 studies were initially searched. We included two cross-sectional studies. Both studies were rated as high risk for bias in exposure measurements and incomplete outcome data. These studies showed conflicting results. One study reported that school bullying was negatively associated with job satisfaction among British lesbian, gay, or bisexual workers; on the other hand, another study reported that school bullying was positively associated with work engagement among Japanese workers. Conclusions: We found limited inconsistent evidence for the association between work-related SWB and school bullying experiences.

Objectives: The translation of lifestyle intervention to improve glucose tolerance into the workplace has been rare. The objective of this meta-analysis is to summarize the evidence for the effectiveness of dietary interventions in worksite settings on lowering blood sugar levels. Methods: We searched for studies in PubMed, Embase, Econlit, Ovid, Cochrane, Web of Science, and Cumulative Index to Nursing and Allied Health Literature. Search terms were as follows: (1) Exposure-based: nutrition/diet/dietary intervention/health promotion/primary prevention/health behavior/health education/food /program evaluation; (2) Outcome-based: diabetes/hyperglycemia/glucose/HbA1c/glycated hemoglobin; and (3) Setting-based: workplace/worksite/occupational/industry/job/employee. We manually searched review articles and reference lists of articles identified from 1969 to December 2016. We tested for between-studies heterogeneity and calculated the pooled effect sizes for changes in HbA1c (%) and fasting glucose (mg/dl) using random effect models for meta-analysis in 2016. Results: A total of 17 articles out of 1663 initially selected articles were included in the meta-analysis. With a random-effects model, worksite dietary interventions led to a pooled -0.18% (95% CI, -0.29 to -0.06; P<0.001) difference in HbA1c. With the random-effects model, the interventions resulted in 2.60 mg/dl lower fasting glucose with borderline significance (95% CI: -5.27 to 0.08, P=0.06). In the multivariate meta-regression model, the interventions with high percent of female participants and that used the intervention directly delivered to individuals, rather the environment changes, were associated with more effective interventions. Conclusion: Workplace dietary interventions can improve HbA1c. The effects were larger for the interventions with greater number of female participants and with individual-level interventions.

Objectives: To clarify the concept of workplace violence in nursing and propose an operational definition of the concept.Methods: The review method used was Walker and Avant's eight-step method.Results: Identification of the key attributes, antecedents, consequences, and empirical referents of the concept resulted in an operational definition of the concept. The proposed operational definition identifies workplace violence experienced by nurses as any act or threat of verbal or physical violence, harassment, intimidation, or other threatening disruptive behavior that occurs at the worksite with the intention of abusing or injuring the target.Conclusions: Developing insights into the concept will assist in the design of new research scales that can effectively measure the underlying issues, provide a framework that facilitates nursing interventions, and improve the validity of future studies.

Objective: To investigate whether implementing a radiation management safety checklist (RMSC) can improve personnel dosimetry among physicians' dosimeter wearing rate for those performing fluoroscopy. Methods: Initially, we visually inspected whether the physicians were wearing personal dosimeters. Subsequently, during a "time-out" period recommended by the RMSC, the medical worker mutually confirmed whether the personal dosimeters were worn correctly. If errors in personnel dosimetry were noted, verbal recommendations to correct the error and follow double dosimetry were made. Lastly, the physicians' dosimeter wearing rates before and during RMSC implementation were compared and analyzed. Results: Before the measurement period, the personal dosimeter wearing rate among all physicians who perform fluoroscopy at the study center (n=72) was 58.2%; during the measurement period, it reached 80.1% (χ2[2]=21.254, p<0.01, φ=-0.227), indicating that RMSC implementation improved the physician's dosimeter wearing rate. However, 40.1% and 37.9% of the physicians were not registered radiation workers before and during the measurement period, respectively, and RMSC implementation did not significantly improve the registration rate during the study period (χ2[2]=0.349, p=0.554, φ=-0.023). Conclusions: The risk of radiation injury may have been overlooked among physicians involved in fluoroscopy and other routine clinical practices that cause radiation exposure. The investigated medical facilities registered physicians as radiation workers at the individual's discretion. There is an urgent need to develop a radiation management system that mandates the use of personal dosimeters among all physicians at risk of radiation exposure.

Objectives: The aim of this study was to validate the Japanese version of the Recovery Experience Questionnaire (REQ-J), which assesses how individuals unwind and recuperate from work during leisure time (i.e., psychological detachment, relaxation, mastery and control). Methods: The translated and back-translated REQ was administered via the Internet to 2,520 Japanese employees from various occupations. Exploratory and confirmatory factor analyses were conducted to evaluate factorial validity. The relationship with potential predictors and consequences of recovery experiences were investigated to evaluate construct validity. Internal consistency was examined to evaluate its reliability. Results: A series of confirmatory factor analyses revealed that the hypothesized four-factor model fit the data best. Construct validity was generally supported by expected correlations of recovery experiences with possible predictors and consequences. Cronbach’s alpha coefficient for each of the four subscales was sufficient (0.85—0.89). Conclusions: This study confirmed that the REQ-J is an adequate measure of recovery experiences that can be used in the Japanese context.

Objective: The present study aimed to estimate cumulative incidence of overweight and obesity and describe 5-year longitudinal changes in body mass index (BMI) in a large occupational cohort in Japan.Methods: Participants were 55 229 Japanese employees, who were aged 20-59 years and attended at all subsequent annual health check-ups between 2009 and 2014. Mixed model analysis was performed to examine the effects of age and cohort by gender on BMI change, with age as a random variable. Cumulative incidence of overweight (23.0≤ BMI <27.5 kg/m2) and obesity (BMI ≥27.5 kg/m2) was calculated. Logistic regression analysis was used to estimate odds ratios for the incidence of overweight and obesity according to age group.Results: The incidence of overweight and obesity was approximately double in men (28.3% and 6.7%, respectively) compared to women (14.3% and 3.9%, respectively). The incidence of obesity decreased with age in men, but did not differ according to age in women (P for trend: .02 and .89, respectively). Among overweight participants, the incidence of obesity was higher in women (18.9%) than men (14.5%) and decreased with advancing age (P for trend: <.001 in men and .003 in women). Mean BMI was higher in men than women in all age groups throughout the period. Younger cohorts tended to have a higher BMI change compared with older cohorts.Conclusions: In this Japanese occupational cohort, transition from overweight to obesity is higher in women than men, and the more recent cohorts had a higher change in mean BMI than the older cohorts.

Objectives: In Japan, employee fitness for work is determined by annual medical examinations. It may be possible to reduce the variability in the results of work fitness determination, particularly for situation, if there is consensus among experts regarding consideration of limitation of work by means of a single parameter. Methods: Consensus building was attempted among 104 occupational physicians by employing a 3-round Delphi method. Among the medical examination parameters for which at least 50% of participants agreed in the 3rd round of the survey that the parameter would independently merit consideration for limitation of work, the values of the parameters proposed as criterion values that trigger consideration of limitation of work were sought. Parameters, along with their most frequently proposed criterion values, were defined in the study group meeting as parameters for which consensus was reached. Results: Consensus was obtained for 8 parameters: systolic blood pressure 180 mmHg (86.6%), diastolic blood pressure 110 mmHg (85.9%), postprandial plasma glucose 300 mg/dl (76.9%), fasting plasma glucose 200 mg/dl (69.1%), Cre 2.0mg/dl (67.2%), HbA1c (JDS) 10% (62.3%), ALT 200 U/l (61.6%), and Hb 8 g/l (58.5%). Conclusions: To support physicians who give advice to employers about work-related measures based on the results of general medical examinations of employees, expert consensus information was obtained that can serve as background material for making judgements. It is expected that the use of this information will facilitate the ability to take appropriate measures after medical examination of employees.

Objectives: To evaluate the effectiveness of a non-vaccine quarantine measure against pandemic influenza A H1N1 in workplaces. Methods: Design was quasi-cluster randomized controlled trial in two sibling companies (Cohort 1 n=6,634, Cohort 2 n=8,500). The follow-up period was from July 1st, 2009 to February 19th, 2010 (233 days). Intervention was voluntary waiting at home on full pay if the family became Influenza like Illness (ILI). The incidences of influenza A H1N1 and those of the subgroups whose families got ILI in both cohorts were compared by a Cox regression model and log-rank test. Results: There were 189 and 270 workers who got H1N1 infection during the follow-up period in each cohort. In this period 317, workers in Cohort 1 were asked to wait at home for several days (100% obeyed). The intervention group (Cohort 1) showed a statistically significant lower risk (p for log-rank test=0.033) compared with the control (Cohort 2), and the hazard ratio of the intervention was 0.799 [0.658-0.970] after adjusting for age, sex, BMI and smoking status. The workers who were asked to wait at home showed H1N1 infection more frequently (49 out of 317) compared with the workers whose family got ILI but were not asked to wait and work regularly (77 out of 990, RR=2.17 [1.48-3.18]). Conclusions: The waiting on full pay policy in the workplace reduced the overall risk of influenza A H1N1 by about 20% in one flu season in Japan. This kind of non-vaccine measure will be a promising option in workplaces to control the next flu pandemic.

Objectives: Presenteeism refers to the condition of working while having health problems and can be one of the perspectives to assess the incompatibility between workers and their jobs. The purpose of this survey was to find out what kind of occupational health issues can be detected by occupational physicians' interviews focusing on presenteeism. Methods: We conducted interviews with workers suffering from presenteeism in a food manufacturing company. The Work Functioning impairment scale (WFun) was used as the indicator of presenteeism. We discussed the occupational health issues and the necessity of additional interventions. Results: Thirty-nine workers with WFun score of 21 or higher were interviewed, and we have found nine cases in need of support. The workplace issues were structured into four categories: (i) health problems that are difficult to identify through health checkups, (ii) health problems missed by the stress check program, (iii) health problems caused by workload that cannot be identified by workplace patrols, and (iv) health problems that are not considered because they do not require support. Conclusions: We discovered new workplace issues by interviewing workers suffering from presenteeism.

Objectives: To identify what types of information were useful and/or difficult to obtain for occupational physicians during the COVID-19 epidemic, and how information should be provided to help occupational physicians in the event of future outbreaks of emerging infectious diseases. Methods: The list was developed by categorizing information about COVID-19 delivered by researchers to a group of occupational physicians after the COVID-19 outbreak. We created a survey and asked the group about the usefulness and ease of obtaining each type of information. Results: In total, 79.1–100% of the occupational physicians said that each type of information was “Useful”. Information on the nature of the virus; clinical course, testing, and treatment; infection prevention measures; regulations in Japan; immigration restrictions in Japan; and guidelines were all considered useful by more than 95%, as was information about the introduction of information aggregation websites by public institutions, academic societies, experts, and others, and sharing of case studies by information distribution group members. These last two items also had a high percentage of respondents who said that they “only obtained the information because it was distributed this way”. Conclusions: Constructing a system for automatic distribution of information that is useful to occupational physicians and difficult to obtain elsewhere may make it easier for occupational physicians to respond more smoothly to emerging infectious disease outbreaks within a company.

Objectives: This study aims to clarify whether work engagement mediates the relationship between job resources (i.e., supervisor support, coworker support, and job control) and work-to-family positive spillover (WFPS) for home-visiting nursing staff. Methods: This cross-sectional study surveyed 15 male and 152 female participating home-visit nursing staff across 108 home-visit nursing stations in Fukuoka Prefecture, Japan. In February 2019, each participant provided informed consent and sociodemographic information, and answered three scales, including the short-form version of the Utrecht Work Engagement Scale in Japanese, the Japanese version of the Survey Work-Home Interaction – Nijmegen (J-SWING), and the Job Content Questionnaire (JCQ-22). We evaluated supervisor support, coworker support, and job control as job resources using the JCQ-22's subscale. We then evaluated WFPS using the J-SWING's subscale. The hypothesized model was then tested using structural equation modeling. Results: Job resources were positively related to work engagement among the home-visit nursing staff; in turn, work engagement was positively related to WFPS. Job resources had no significant relationship with WFPS. These results suggest that work engagement mediates the relationship between job resources and WFPS. Conclusions: This study found that job resources were not directly related to WFPS for home-visit nursing staff. However, work engagement mediated the relationship between job resources and WFPS.

Objectives: This study aimed to compare the longitudinal change of the psychological distress of healthcare workers (HCWs) with non-HCWs during the repeated outbreaks of the COVID-19 in Japan.Methods: The data were retrieved from the Employee Cohort Study in the Covid-19 pandemic in Japan study. An online survey was conducted on March 2020 (T1), on May 2020 (T2), on August 2020 (T3), and on November 2020 (T4). Psychological distress was measured by the Brief Job Stress Questionnaire. A mixed-model repeated-measures ANOVA was conducted as an indicator of the group differences.Results: A total sample of analysis was n = 996 (HCWs, n = 111; non-HCWs, n = 885). HCWs consisted of physicians/nurses/midwives and other HCWs (eg, pharmacists, clinical laboratory technicians) in the clinical settings (n = 19; 17% and n = 61; 55%, respectively), and HCWs not working in the clinical settings (n = 31; 28%). Being HCWs were associated with a significant increase in psychological distress from T1 to T2, T3 and T4 (P = .001, P = .002, P < .001; respectively).Conclusions: The mental health of HCWs deteriorated through the COVID-19 outbreaks compared with non-HCWs. HCWs are continuously the important targets to provide mental health support.

Objectives: Cerebrovascular and cardiovascular diseases (CCVDs) and mental disorders, including suicide, are prevalent among overworked individuals in Japan. The 2014 legislation regarding the prevention of overwork-related deaths and disorders has accelerated the research in this field and ultimately the implementation of preventive actions.Methods: To understand the current problematic situations, the Research Center for Overwork-Related Disorders of the National Institute of Occupational Safety and Health, Japan, conducted analyses of compensated claims for overwork-related CCVDs and mental disorders that were recognized from January 2010 to March 2015.Results: The majority of CCVD cases were the men in their 50s. Transport and postal activities was the highest risk industry. Cerebrovascular cases were higher than cardiovascular ones. Long working hours was the principal factor for CCVDs. The mental disorder cases comprised approximately 70% men and affected younger age groups (peak in the third decade) with various industries at risk. In men, there was an almost equal number of F3 (Mood [affective] disorders) and F4 (Neurotic, stress-related, and somatoform disorders) diagnoses according to the 10th revision of the International Classification of Diseases and Related Health Problems. A larger number of women were diagnosed to have F4. The mental disorder cases were associated not only with long working hours, but also with injuries and disasters as well as interpersonal conflict at work.Conclusions: Multiple, simultaneous actions need to be made by employees, employers, researchers, and the authorities to achieve the goal of reducing the number of workers suffering from the overwork-related CCVDs and mental disorders.

Objectives: Workplace gratitude is important for improving work-related outcomes and individual well-being. Although the gratitude at work scale (GAWS) was developed in the United States, it has not been corroborated in Asian countries with interdependent cultures. This study aimed to develop and validate the GAWS among Japanese workers.Method: Japanese workers completed online surveys at baseline (N = 206) and 2 weeks later (N = 103). The Japanese GAWS was developed according to the international guidelines. We measured (a) trait gratitude as comparison for the criterion-related validity, (b) work-related outcomes/factors (eg, work engagement), and (c) well-being (eg, eudemonic well-being at work) as comparisons for convergent validity. Cronbach's alpha, intra-class correlation coefficients (ICCs), and measurement errors were calculated to assess reliability; measurement validity was evaluated by correlational analyses and confirmatory factor analysis (CFA).Results: A total of 206 and 93 workers were included for baseline and follow-up analyses, respectively. Cronbach's alpha and ICCs of the Japanese GAWS ranged from 0.81 to 0.91. CFA showed that the 2-factor model (ie, gratitude for (a) a supportive work environment and (b) meaningful work) demonstrated a good fit (χ2 (34) = 67.58, CFI = 0.967, TLI = 0.956, RMSEA = 0.069, SRMR = 0.037), similar to the original version. As we had hypothesized, overall GAWS and the two domains were significantly correlated with trait gratitude, work-related outcomes/factors, and well-being.Conclusions: The Japanese GAWS demonstrated good reliability and validity. Future research should explore mechanisms related to workplace gratitude and further intervention studies among workers.

Objectives: To preliminarily determine the effects of an Internet-based cognitive behavioral therapy program for the stress management of new graduate nurses on improving depressive symptoms and other psychological outcomes using a pre-post experimental design. Methods: A 6-week, six-lesson Internet-based cognitive behavioral therapy program was developed through an extensive interviewing of nurses. The program utilized major cognitive behavioral therapy skills (self-monitoring, cognitive restructuring, assertiveness, problem-solving, and relaxation). We administered the Internet-based cognitive behavioral therapy program to participants who were at 5 months after starting their job. At baseline and post-intervention, we measured the primary outcome of depressive symptoms along with the secondary outcomes of psychological distress, dysfunctional attitude, and knowledge of and self-efficacy for the components of cognitive behavioral therapy. Results: Twenty-three new graduate nurses were recruited, although only 21 actually took part in the program. Twelve (57%) participants completed all six lessons, and about one-third of participants completed less than three lessons. At post-intervention, only 12 of the 21 participants had completed the post-intervention survey. The program failed to show significant intervention effects on depressive symptoms, psychological distress, and dysfunctional attitude, but it did show significant or marginally significant improvements in knowledge of and self-efficacy for most cognitive behavioral therapy components. Conclusions: The relatively low intensity of the program may explain the null findings. This suggests a need for further improvement of the content and mode of delivery. Nevertheless, the program was able to improve knowledge of and self-efficacy for most cognitive behavioral therapy components.

Objectives: It is unclear whether mandatory health examination is effective for employees who are already being treated for chronic diseases. We focused on patients being treated for hypertension and evaluated the association between employer-based health examination attendance and diabetes treatment initiation.Methods: Using a database that stores health insurance claims and health examination results of subscribers enrolled in society-managed health insurance plans in Japan, we identified employees aged 40-59 years who were being treated for hypertension when starting diabetes treatment from April 2012 to December 2016. A case-crossover analysis was conducted using 90, 180, and 270 days prior to diabetes treatment initiation as reference points and 90 days after the mandatory health examination as the exposure period. We conducted a subgroup analysis by hemoglobin A1c (HbA1c) level and frequency of outpatient blood glucose testing before the mandatory health examination.Results: We identified 1464 individuals starting treatment for diabetes while on antihypertensive drugs. The overall odds ratio for starting diabetes treatment within 90 days of the health examination was 1.89 (95% confidence interval: 1.70-2.10). The subgroup analysis showed that this odds ratio increased as HbA1c level increased and as blood glucose testing frequency decreased.Conclusions: Among employees starting treatment for diabetes while being treated for hypertension, employer-based mandatory health examination attendance was associated with initiation of diabetes treatment. The health examinations may be functioning as a complement to screening in outpatient settings.

Objectives: The working-age population is rapidly declining in Japan, so the government has adopted “health and productivity management” (HPM). This policy initiative aims to encourage corporations to view health promotion activities as an investment in their employees’ health. The objective of this study was to examine the association between organizational factors and knowledge of the organization's effectiveness and program participation levels, and to understand the factors that affect effectiveness of corporations’ activities.Methods: We used data from all corporations that completed the HPM Survey Sheets in 2018 (n = 1800). The explanatory variables were organizational factors: written company-wide policy, agenda item at management-level meetings, regular education for managers, and full-time occupational health staff. The outcome variables were knowledge of the corporation's status on the effectiveness indicators (employees’ exercise habits, risk for high blood pressure, visiting hospital after a health examination, and long-term sickness absences) and rates of participation in four areas (health education, exercise program, dietary program, and influenza vaccination). The associations between organizational factors and knowledge on effectiveness indicators and rates of program participation were analyzed using multiple logistic regression analysis.Results: All the organizational factors were related to knowledge of effectiveness indicators, but only some were associated with the program participation indicators in the model, including all explanatory variables.Conclusion: Enhancing organizational factors may lead to improvement of HPM programs and higher program participation among employees in corporations.

Although some evidence suggests that exercise may improve mental health status, information regarding the intensity and duration of exercise is incomplete. The purpose of this study was to elucidate the association between physical activities in both leisure time and commuting to work and mental health. A questionnaire survey was conducted at three municipal offices in Japan. A total of 670 men and women completed the questionnaire. Mental health status was assessed by the 28-item General Health Questionnaire (GHQ). Respondents were asked about weekly hours of leisure-time exercise for four levels of exercise, and the volume of exercise was assessed using a metabolic equivalent task index. Information about commuting to work on foot or by bicycle was also obtained. The mean GHQ scores were calculated according to physical activity levels using analysis of covariance with adjustment of potential confounders including job stress. In men, the GHQ score decreased steadily with increasing levels of leisure-time exercise, and an inverse association was evident even for mild intensity exercise. Moreover, the GHQ score decreased according to increasing duration of time on commuting to work by either walking or cycling in men, but not in women. These relations did not materially change after adjustment for potential confounding factors. In women, there was no significant association between any of the indices of physical activity. In conclusion, leisure-time exercise and walking or cycling during commuting to work may be associated with better mental health in men.

Objectives: The present study aimed to examine the buffering effect of workplace social capital (WSC) on the association of job insecurity with psychological distress in Japanese employees. Methods: 2,971 employees from two factories of a manufacturing company in Japan completed a self-administered questionnaire including the scales on job insecurity, WSC, psychological distress, demographic and occupational characteristics, and quantitative workload. Using psychological distress (defined as a total score of the K6 scale ≥5) as a dependent variable, multiple logistic regression analyses were conducted. In a series of analyses, interaction term of job insecurity×WSC was included in the model. Results: After adjusting for demographic and occupational characteristics as well as for quantitative workload and interaction effect of quantitative workload×WSC, high job insecurity and low WSC were significantly associated with psychological distress. Furthermore, a significant interaction effect of job insecurity×WSC was observed. Specifically, the association of job insecurity with psychological distress was greater among those who perceived lower levels of WSC (prevalence odds ratio=3.79 [95% confidence interval=2.70-5.32] for high vs. low job insecurity subgroup) than among those who perceived higher levels of WSC (prevalence odds ratio=2.96 [95% confidence interval=2.19-4.01] for high vs. low job insecurity subgroup). These findings were replicated among permanent male employees in the gender-stratified analyses. Conclusions: The present study suggests that WSC has a buffering effect on the association of job insecurity with psychological distress at least among Japanese permanent male employees.
