Abstract
OBJECTIVES This study investigates the association between workaholism and headaches causing presenteeism among Japanese employees. METHODS Used data from self-reporting questionnaire and annual health checkups. Workaholism was assessed using the Dutch Workaholic Scale and headaches causing presenteeism were identified as the symptom hindering work. We performed a logistic regression analysis adjusted for covariates. RESULTS Among 5,802 respondents, 3.7% cited headaches as the symptom hindering work. We found an association between workaholism and such headaches (Odds ratios [OR]: 1.05, 95% confidence intervals [CI]: 1.03-1.08). Both working excessively (OR: 1.08, 95% CI: 1.04-1.12) and working compulsively (OR: 1.10, 95% CI: 1.05-1.15) subscales were also related. CONCLUSIONS Workaholism may lead to productivity loss due to headaches, and addressing workaholism can prevent this loss. Combining health examination data with work hours data may enable the early detection of workaholism.

Abstract
AIMS To evaluate the relationship between diabetes treatment status and occupational accidents. METHODS A cross-sectional study was conducted using an online questionnaire survey completed in March 2022 among workers aged 20 years or older. The questionnaire included questions about diabetes treatment status and occupational accidents. The association between the treatment status of diabetes and occupational accidents was examined using a logistic regression analysis. RESULTS The study included 25,756 participants with no diabetes, 1,364 participants receiving diabetes treatment, 177 participants who had interrupted diabetes treatment, and 396 participants who needed diabetes treatment but had not seen a doctor. Compared with those with diabetes treatment, the odds ratio of occupational accidents among participants without diabetes was 0.40 (95% CI: 0.32-0.49), the odds ratio among participants with interrupted diabetes treatment was 4.15 (95% CI: 2.86-6.01), and the odds ratio among participants who needed diabetes treatment but had not seen a doctor was 1.25 (95% CI: 0.89-1.77). CONCLUSIONS This study showed that diabetes treatment status was related to occupational accidents, and it may be important for workers with diabetes to be supported to balance their diabetes management and their work commitments.

Abstract
OBJECTIVES In Japan, the most common injury requiring sick leave is a fall in the workplace; therefore, it is very important to prevent falls. Most measures to prevent falls involve aspects of the workplace environment and safety. However, few measures consider the perspective of individual health. We investigated the relationship between psychiatric disorders and falls in the workplace and whether treatment status for a psychiatric disorder is associated with workplace falls. METHODS We conducted a cross-sectional study among workers aged 20 years or older in Japan from February 28 to March 3, 2022. In total, the data of 27 693 participants were analyzed. We used a questionnaire to query participants' status of treatment for any psychiatric disorder and whether they had experienced a fall in the workplace. The association between treatment for a psychiatric disorder and workplace falls was examined using logistic regression analysis. RESULTS Compared with participants receiving appropriate treatment for a psychiatric disorder, the odds ratio (OR) of a workplace fall was significantly lower among participants who did not require treatment for a psychiatric disorder, at 0.56 (95% CI: 0.47-0.66; P < .001); the OR of a workplace fall was significantly higher among participants whose treatment for a psychiatric disorder was interrupted, at 1.47 (95% CI: 1.21-1.78; P < .001), after adjusting for age, sex, household income, number of workplace employees, sleeping hours, exercise habits, and psychological distress. CONCLUSIONS Our findings suggest that receiving appropriate treatment for psychiatric disorders may contribute to preventing falls in the workplace.

Abstract
OBJECTIVES The study objective was to measure the association between exposure to technological advances and work engagement, adjusting for personal and workplace factors. METHODS We conducted a nationwide online longitudinal survey study in Japan. The sample was stratified to represent Japanese workforce conditions. Work engagement was measured using the Japanese version of the Utrecht Work Engagement Scale-9. Exposure to technological advances was measured using a single question with Likert scale responses. Industry characteristics that were more/less likely to be replaced by automation were also measured. Linear regression was used for statistical analysis. RESULTS There were 16 629 participants. We found that exposure to technological advances was associated with work engagement after adjustment for age, sex, education, income, and industry characteristics. We observed a significant interaction between age and exposure to technological advances (coefficient 0.891, P < .001), and conducted an age-stratified linear regression analysis. The significant association between age and exposure to technological advances reduced as age increased, and disappeared after adjustment for baseline work engagement. CONCLUSIONS Longitudinal observations showed that exposure to technological advances was not significantly associated with work engagement.

Abstract
We aim to conduct a prospective cohort study to benchmark occupational health and safety in Japan. Here, we describe the detailed protocol for the baseline survey based on the Checklist for Reporting Results of Internet E-Surveys. We conducted the baseline survey for the prospective cohort study in 2022. Our target population was workers in Japan aged 20 years or older, who we sampled to be representative of the Japanese workforce, stratified by sex, age, and region. Among 59,272 registered monitors who answered the initial screening questions, 29,997 completed the survey. After excluding 2,304 invalid responses, we used 27,693 valid participants in our final analysis. The number and mean age of men were 15,201 (55%) and 46 years; those of women were 12,492 (45%) and 45 years. With respect to sex, age, and regional composition, our sampling was representative of Japan's working population. Our sampling for employment status and industry yielded almost the same proportions as a government-led representative sampling of workers in Japan.

Abstract
BACKGROUND Presenteeism is affected by work-related and individual factors. Among individual factors, the effect of combining various lifestyle habits on presenteeism is unknown. AIMS This study aimed to determine the relationship between changes in multiple good lifestyle habits with a change in presenteeism and to examine the effect of psychological factors on this relationship. METHODS We performed a 1-year retrospective cohort study on employees of large Japanese companies. Data were collected from health check-ups and a self-administered questionnaire. Changes in presenteeism were measured using the Quality and Quantity method. Changes in lifestyle habits were measured using a modified form of Breslow's seven health practices. Psychological factors were measured using the Kessler 6-Item Psychological Distress Scale. Linear regression was used for statistical analysis. RESULTS The number of practised lifestyle habit changes was negatively correlated with a change in presenteeism. This result was consistent when adjusted for age, sex and company (B, -0.010; P < 0.05), but became non-significant when additionally adjusted for psychological distress (B, -0.006). When analysed separately, only an improvement in the body mass index (B, -0.054; P < 0.05) and a worsened sleep habit (B, 0.040; P < 0.01) influenced a change in presenteeism. CONCLUSIONS This study suggests that improving various practised lifestyle habits in combination, rather than improving a single lifestyle habit, is beneficial in reducing presenteeism. Our finding that psychological distress altered the relationship of practised lifestyle habit changes with presenteeism indicates the importance of organizational-level intervention in presenteeism.

Abstract
OBJECTIVE This study was identified seeking treatment for hypertension and diabetes among male shift workers. METHOD This retrospective cohort study included nine large companies in Japan. Data were collected from health checkup, health insurance records, and self-administered questionnaires in 2017 and 2020. Data were analyzed using Kaplan-Meier curves and Cox regression. RESULT Person-days shift workers and day workers seeking treatment for hypertension were 41,604 and 327,301, respectively and, for diabetes, were 7326 and 60,735, respectively. The log ranks were statistically significant. Shift workers were 46% and 56% less likely to seek treatment for hypertension and diabetes, respectively, than day workers were after adjustment for age, marital status, education level, and intention to modify lifestyle (model 2) ( P < 0.01). CONCLUSIONS Male shift workers are less likely to seek treatment for hypertension and diabetes compared with day workers.

Abstract
OBJECTIVES We investigated the relationship between employees' perceptions of the number of sources of workplace social support and work engagement and whether each type of workplace social support is independently related to work engagement. METHODS A cross-sectional study was conducted using a questionnaire survey in Japan. In total, 12,017 participants were analyzed. Participants were asked about 4 sources of workplace social support: supervisors, colleagues/subordinates, occupational health staff, and external counselors contracted by the workplace. Work engagement was measured using the 9-item Utrecht Work Engagement Scale. Coefficients were estimated using multiple regression analyses. RESULTS The coefficient of work engagement increased as the number of sources of perceived workplace social support increased. Each support was also positively related to work engagement. CONCLUSIONS Organizations should develop systems comprising various sources of workplace social support to increase employee work engagement.

Abstract
OBJECTIVE This study aimed to structure supervisory support and clarify the relationship between supervisors' work engagement and support for their subordinates. METHODS We conducted a cross-sectional study in a manufacturing company using a questionnaire survey. Supervisors provided open-ended responses regarding the provision of support for their subordinates. Using text mining, we structured these descriptions into multiple categories, assigned words to them, and analyzed frequently mentioned categories by the level of work engagement. RESULTS We obtained responses from 729 participants that included 13,968 words. We structured supervisory support by three categories (contents, direction, and attitude toward support) and 11 subcategories. As supervisors' work engagement increased, the rates of mentioning information retrieval, information transmission, and carefulness increased. CONCLUSIONS Supervisors with work engagement could communicate with each other and be careful in providing support to their subordinates.

Abstract
It has not been established how to assess children's and adolescents' decision-making capacity (DMC) and there has been little discussion on the way their decision-making (DM). The purpose of this study was to examine actual situation and factors related to difficulties in explaining their disease to adolescent cancer patients or obtaining informed consent (IC). The cross-sectional questionnaire survey was conducted. Physicians who have been treating adolescent cancer patients for at least five years answered a self-administered questionnaire uniquely developed about clinical difficulties in explaining, IC and factors related patient's refusal of medical treatment (RMT). Descriptive statistics for each item and a polychoric correlation analysis of the problems and factors related to the explanation were conducted. As a result, fifty-six physicians were participated (rate of return: 39%). Explaining the disease and treatment to patients (83.9%), IC to patients (80.4%), and explaining the disease and treatment to parents (78.6%) was particularly problematic. Difficulties to provide support related with patient's refusal of medical treatment and to explain disease and treatment for patient and parents were related to difficulties obtaining IC for the patient. Conclusion: There are clinically difficult to explain for the patient or parents and to obtain IC for the patient. It is necessary to establish a disease acceptance assessment tool for the adolescence generation so that it can be applied in the field.

Abstract
The working-age population is at the epicenter of coronavirus disease 2019 (COVID-19) infections. Therefore, it is important to increase the acceptance of digital contact tracing apps in this population. Contact-Confirming Application (COCOA) is the only digital contact tracing app in Japan. This study aimed to determine factors associated with acceptance of the COCOA for COVID-19 in the Japanese working-age population. A cross-sectional study was performed for 27,036 full-time workers registered with an internet survey company during December 2020 in Japan. Factors associated with COCOA adoption were evaluated by multivariate logistic regression analysis. The rate of downloading the COCOA was 25.1%. The COCOA was more likely to be accepted by people with married status, university graduation or above, higher income, and occupations involving desk work. Fear of COVID-19 transmission, wearing a mask, using hand disinfection, willingness to be vaccinated against COVID-19, and presence of an acquaintance infected with COVID-19 were also associated with a greater likelihood of adopting the app. The rate of downloading the COCOA in Japan was not very high. The present findings have important implications for widespread adoption of digital contact tracing apps in working-age populations in Japan and elsewhere.

Abstract
OBJECTIVE This study aimed to evaluate the association between the type of chronic disease and receiving workplace accommodations. METHODS This online cross-sectional study analyzed a self-reported questionnaire administered in Japan. A total of 6775 full-time workers who reported needing work accommodations were included. RESULTS Workplace accommodations were more likely to be provided for workers with cancer, mental illness, and benign gynecological disorders than for workers with no disease under treatment. In contrast, workplace accommodations were less likely for workers with low back pain and skin diseases. CONCLUSIONS Receiving workplace accommodations depends on the type of chronic disease. Chronic diseases for which workers frequently receive workplace accommodations may be those for which support is encouraged by law. It is necessary to support workers with chronic diseases that do not receive adequate workplace accommodations.

Abstract
OBJECTIVES The purpose of this study was to examine, by sex, whether precarious workers in Japan receive less support in the workplace than permanent workers. METHODS We conducted a cross-sectional study using an online questionnaire in 2022. We stratified participants by sex and performed modified Poisson regression analysis. The outcomes were support from supervisors, co-workers, occupational health professionals, and no one. Adjusted prevalence ratios (aPR) were calculated for contract workers, part-time workers, and dispatched workers, using permanent workers as reference. RESULTS This study had 21 047 participants. For men, 87.9% were permanent workers; for women, 50.7% were permanent workers and 37.3% were part-time workers. For workplace support, 47.5% of men and 45.2% of women selected superiors; 41.8% of men and 50.5% of women selected colleagues; 16.8% of men and 6.2% of women selected occupational health professionals. Female contract workers were less likely to receive support from their supervisors (aPR 0.88) or co-workers (aPR 0.89). Male part-time workers were less likely to be supported by their co-workers (aPR 0.86). Dispatched workers were less likely to be supported by their supervisors (men aPR 0.71, women aPR 0.84) and co-workers (men aPR 0.73, women aPR 0.77). Part-time and dispatched workers were less likely to receive support from occupational health professionals. CONCLUSIONS Precarious workers could get less workplace support than permanent workers. This may contribute to occupational health problems with precarious workers.

Abstract
Background
Although lifestyle interventions are useful in the prevention and management of diabetes, they can be expensive and time-consuming. There is some evidence on the effectiveness of automated mobile technology for health self-monitoring; however, few studies have used such devices in the occupational health field.
Objective
We aimed to examine the effectiveness of a digital self-monitoring device on glucose levels and activity of workers with diabetes in Japan. The primary outcomes were changes in blood glucose levels, and the secondary outcomes were changes in weight and BMI.
Methods
A 2-arm randomized controlled pilot trial was conducted with workers from 23 organizations. The intervention group (n=50) wore an armband activity monitor, a body composition monitor, and a blood pressure monitor for 3 months and received semiautomated weekly email messages tailored to their device data. The control group (n=53) engaged in no self-monitoring. Messages were developed by a physician and a dietician. Postintervention changes in blood glucose levels, weight, and BMI were compared between the intervention and control groups, using blood tests and questionnaires.
Results
At the end of 3 months, the intervention group showed significantly lower blood glucose levels (HbA1c: intervention group mean 6.4% (SD 0.3%) vs control group mean 6.6% (SD 0.3%); Cohen d=0.7, 95% CI 0.2-1.1; P=.009). There were no significant between-group differences in weight and BMI.
Conclusions
Mobile digital self-monitoring was effective in improving blood glucose levels in workers with diabetes. The use of digital health devices is a cost-effective way of implementing health self-monitoring for large numbers of individuals in the workplace. However, due to the large volume of missing values in this study, we need to be careful in interpreting the results, and well-designed intervention studies need to be conducted.

Abstract
Objective This study examined the association between increased alcohol consumption and telecommuting, comparing employees who expressed a preference for telecommuting and those who did not. Methods We conducted an internet monitor survey. Responses from 20 395 of the 33 302 participants were included in the final sample. Participants were asked about their desire for and frequency of telecommuting, and about changes in alcohol consumption under the COVID‐19 pandemic. Data were analyzed by logistic regression analysis. Results The ratio of increased drinking in those who telecommuted at least once a week was significantly different (OR = 1.29, 95% CI 1.16–1.43, p < .001). The ratio of increased drinking in participants for whom telecommuting was not preferred was significantly different (OR = 1.08, 95%CI 1.02–1.14, p = .002). Since the interaction term was significant in preliminary analysis, stratification was performed. Participants who telecommuted despite preferring not to do so reported significantly increased alcohol consumption, as revealed by a multivariate analysis (OR = 1.53, 95% CI 1.18–2.00, p < .001). Participants who expressed a preference for telecommuting showed no such increase (OR = 1.12, 95% CI 0.98–1.27, p = .074). Conclusions Under the COVID‐19 pandemic, telecommuting that involves a mismatch with employee preference for way of working may be a new risk factor for problematic drinking.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic has been linked to a rise in loneliness. Loneliness is associated with sleep-related problems, which in turn can be a risk factor for various psychiatric disorders. However, it is unclear whether loneliness is linked to sleep-related problems during the pandemic. Here, we studied the association between loneliness and sleep-related problems during the COVID-19 pandemic in Japan. Methods A total of 33,302 individuals who indicated they were employed were surveyed online. The survey responses of 27,036 participants were analyzed. Odds ratios (ORs) were estimated using univariate and multiple logistic regression analyses. Results Of those analyzed, 2,750 (10.2%) experienced feelings of loneliness. Further, sleep-related problems were significantly more common among those who felt lonely both in the short term (more than 3 days) and the long term (more than 3 months). The ORs were much weaker after adjusting for factors related to interpersonal connections, such as family and friendships, than after adjusting for factors related to socioeconomic status. Conclusion Loneliness may be a risk factor for sleep-related problems in the COVID-19 pandemic. Having connections with family and friends may have a moderating effect on the occurrence of sleep-related problems.

Abstract
OBJECTIVES This study aimed to investigate the relationship of diarrhea/constipation symptoms with presenteeism and psychosocial work environment factors. METHODS This study analyzed 16,975 workers of 10 Japanese companies. Presenteeism was measured using a work functioning impairment scale. Odds ratios (ORs) and 95% confidence intervals (cis) for the relationship between diarrhea/constipation and presenteeism were estimated using a logistic model, adjusting for the psychosocial work environment. RESULTS Diarrhea/constipation symptoms were related to presenteeism. This relationship was weakened, but remained significant after adjusting for psychosocial work environment factors. CONCLUSIONS Diarrhea and constipation, which are highly prevalent in the workplace, are important pathological factors for presenteeism. Presenteeism can be partially suppressed by improving the psychosocial work environment.

Abstract
Objectives The purpose of this study was to investigate the relationships of workers being diagnosed with coronavirus disease 2019 (COVID‐19) and being identified as close contacts of infected persons with unemployment in Japan. Methods This was a prospective cohort study using questionnaires about COVID‐19 administered to Japanese workers. A baseline survey conducted on December 22–25, 2020, was used to determine history of being diagnosed with COVID‐19 or being identified as a close contact of an infected person. Unemployment since the baseline survey was ascertained with a follow‐up survey on February 18 and 19, 2021. The odds ratios (ORs) of unemployment were estimated using a multilevel logistic model with adjusted covariates nested in prefecture of residence. Results Women (n = 8771) accounted for 44% of the total sample (n = 19 941), and the mean age was 48.0 years. In terms of unemployment because of negative reasons, the multivariate analysis showed that the OR of unemployment associated with being diagnosed with COVID‐19 was 2.40 (95% CI: 1.15–5.01) and that the OR associated with being identified as a close contact was 0.98 (95% CI: 0.31–3.11). Conclusions There is an association between workers being diagnosed with COVID‐19 and unemployment. The reason is not clear, but if the unemployment is unwanted by the individual, workplace adjustment may help prevent unwilling unemployment.

Abstract
OBJECTIVES This study sought to examine differences in the economic losses due to presenteeism and costs of medical and dental treatment between high-stress workers and non-high-stress workers using the stress check survey. METHODS We conducted a cross-sectional study from April 1, 2018 to March 31, 2019 in a pharmaceutical company. High-stress workers were classified with the Brief Job Stress Questionnaire using two methods: the sum method and the score converted method. The incidence of presenteeism and its costs were determined using a questionnaire. The costs of medical and dental treatment were calculated according to claims. We compared the costs between high-stress and non-high-stress workers using Wilcoxon's rank-sum test. RESULTS Of 3910 workers, 6.3% were classified as high-stress using the sum method and 6.6% were classified as high-stress using the score converted method. The costs associated with presenteeism and medical treatment among high-stress workers were higher than the costs among non-high-stress workers, whereas the costs associated with dental treatment were not. CONCLUSIONS To motivate employers to improve stressful work environments, it is recommended that presenteeism measurement items be added to the stress check survey, and that the methods used in this study be used to calculate the loss associated with high-stress workers in Japanese companies. However, we must be careful in interpreting absolute presenteeism loss amounts because they are poorly reliable and valid.

Abstract
OBJECTIVES The study examined a relationship between organizational factors and the health outcomes (health behaviors and blood pressure control) at a company level. METHODS This cross-sectional study using data from listed corporations on a stock exchange with 1000 to 30,000 employees that completed the health and productivity management survey of Japan in 2019. RESULTS We analyzed 886 companies. The presence of occupational health staff was associated with good health behaviors (no smoking and healthy body mass index) and good control of blood pressure. Implementation of education for manager was associated with low smoking rates. CONCLUSION The implementation of organizational factors by corporations may improve the lifestyle behaviors and disease management of their employees.

Abstract
OBJECTIVES The present study examined the relationship between health culture evaluated by the Health and Productivity Survey Sheets and the implementation status of infection control measures against COVID-19 in the workplace. METHODS This was a cross-sectional study using the corporate data (2518 companies) collected for the purpose of selecting the excellent company of health and productivity management by the Japanese government. The explanatory variable was the overall evaluation score, and the outcome was whether or not infection control measures against COVID-19 in the workplace. We used logistic regression analysis and calculated the odds ratio adjusted for the industry sector, the corporation size, and the operating profit ratio by the overall evaluation score category. RESULTS The odds ratio of all infection control measurements in the workplace increased as the evaluation score increased. CONCLUSIONS This study revealed a new finding that the presence of a healthy culture in the workplace will lead to the appropriate implementation of infection control measures during a pandemic. The company's ordinary commitment to employee health will be effective even in times of health crisis, such as during the outbreak of the pandemic.

Abstract
Objectives Although gender stereotypes regarding paid work and unpaid work are changing, most wives are responsible for taking care of the family and home in Japan. It is unclear how time spent on housework and childcare has changed between working men and women during the COVID‐19 pandemic in Japan. The purpose of this study is to investigate how working men and women’s responsibilities for housework and childcare changed during the COVID‐19 pandemic in Japan depending on work hours, job type, the number of employees in the workplace, and frequency of telecommuting. Methods A cross‐sectional analysis (N = 14,454) was conducted using data from an Internet monitoring study (CORoNa Work Project), which was conducted in December 2020. A multilevel logistic model with nested prefectures of residence was conducted to estimate the odds ratio (OR) for change in time devoted to housework and childcare among men and women adjusting for age, household income, presence of spouse who work, work hours, job type, the number of employees in the workplace, frequency of telecommuting, and the incidence rate of COVID‐19 by prefecture. Results More women tended to perceive that their time of housework and/or childcare had been changed (increased housework: OR 1.92, 95% CI [1.71–2.16], P < .001; decreased workhours: 1.66 (1.25–2.19), P < .001: increased childcare: OR 1.58, 95% CI [1.29–1.92], P < .001; decreased childcare: 1.11 (0.62–2.00), P = .719). Conclusions The time spent by women on housework and childcare changed significantly compared to men during the COVID‐19 pandemic in Japan.

Abstract
Although multilayered strategies including preventive behaviors should be adopted to mitigate coronavirus disease 2019 (COVID-19) transmission, evidence on the effectiveness of preventive behaviors against COVID-19 remains limited. This Internet-based prospective cohort study collected baseline data in November 2020 and follow-up data in February 2021, during the third wave of the epidemic in Japan. Among the 19 941 included participants, the percentages reporting that they always used a face mask, practiced hand washing/disinfection, gargling, and ensuring proper room ventilation were 85.4%, 36.0%, 51.1%, and 44.6%, respectively. Multiple logistic regression analyses revealed that less frequently practicing hand washing/disinfection (odds ratio [OR] = 1.20, 95% confidence interval [CI]: 1.10-1.32), gargling (OR = 1.20, 95% CI: 1.10-1.30), and ensuring proper room ventilation (OR = 1.38, 95% CI: 1.26-1.52) were significantly associated with self-reported COVID-19-like illness (CLI). These results suggest that personal preventive behaviors may be effective in reducing CLI, even when universal masking is practiced.

Abstract
OBJECTIVE The present study examined the relationship between the intensity of home-based telework and work engagement. METHODS This cross-sectional study using a self-administrated questionnaire survey was conducted from December 22 to 25, 2020, in Japan. The subjects were asked single-item questions about the intensity of telework and three-item questions about work engagement using the Utrecht Work Engagement Scale. Coefficients were estimated using a multilevel regression model nested by the prefecture of residence and adjusted for covariates. RESULTS High-intensity (4 or more days per week) telework was not associated with high work engagement for men or women. In contrast, low and moderate intensity (3 days per week to once per month) were associated with high work engagement. The results were consistent when stratified by sex. CONCLUSIONS Reasonable-intensity telework may have beneficial effects on work engagement.

Abstract
The purpose of this study was to examine the association between loneliness and psychological distress during the COVID-19 pandemic in Japan. We conducted a cross-sectional online study from 22 to 26 December 2020. A total of 27,036 participants, all employed at the time, were included in the analysis. Participants were asked if they felt loneliness in a single-item question. The Kessler 6 (K6) was used to assess psychological distress, defined as mild for K6 scores of 5 to 12 and severe for 13 or higher. The odds ratios (ORs) of psychological distress associated with loneliness were estimated using a multilevel logistic model nested in the prefecture of residence, with adjustment for age, sex, marital status, equivalent income, educational level, smoking, alcohol consumption, job type, number of workplace employees, and cumulative incidence rate of COVID-19 in the prefecture. Communication with friends, acquaintances, and family was strongly associated with psychological distress, so we adjusted for these factors and eating meals alone. Results showed a significant association between loneliness and psychological distress (OR = 36.62, 95% CI = 32.95–40.69). Lack of friends to talk to, lack of acquaintances to ask for help, and lack of people to communicate with through social networking sites were all strongly associated with psychological distress, as were family time and solitary eating. Even after adjusting for these factors, loneliness remained strongly associated with psychological distress (OR = 29.36, 95% CI = 26.44–32.98). The association between loneliness during the COVID-19 pandemic and psychological distress indicates the need for intervention.

Abstract
BACKGROUND The number of people with diabetes is increasing and resulting in major economic losses. Presenteeism accounts for the majority of economic losses, so measures against presenteeism are important. This study investigated the relationship between severity of type 2 diabetes and presenteeism. METHODS A cross-sectional study was conducted among workers over 40 years of age. Participants were classified as normal group or diabetic treatment group using their medical examination results and health insurance claims data. Diabetic treatment groups were described by degree of treatment control: Good (HbA1c < 7%), Intermediate (7% ≤ HbA1c < 8%), and Poor (8% ≤ HbA1c). Therapy type was also divided into monotherapy and combination therapy. Logistic regression analysis was performed to predict presenteeism loss using the Quantity and Quality method. RESULTS Data on 13,271 workers were analyzed. Presenteeism loss was significantly higher in all treatment control groups compared with the normal group, particularly for the intermediate and poor control groups. The monotherapy group did not differ from the normal group, but presenteeism loss was significantly higher in the combination therapy group than the normal group. CONCLUSIONS Presenteeism loss in workers with diabetes may be affected by diabetes severity, and even if treatment control were good, presenteeism loss could occur when the number of anti-diabetic drugs was high. Therefore, it is important to provide early intervention and continuous support as a preventive measure against not only diabetes and diabetes-related complications but also presenteeism.

Abstract
BACKGROUND To combat coronavirus disease 2019 (COVID-19), many countries have used contact tracing apps, including Japan's voluntary-use contact-confirming application (COCOA). The current study aimed to identify industry and workplace characteristics associated with the downloading of this COVID-19 contact tracing app. METHODS This cross-sectional study of full-time workers used an online survey. Multiple logistic regression analysis was used to evaluate the associations of industry and workplace characteristics with contact tracing app use. RESULTS Of the 27,036 participants, 25.1% had downloaded the COCOA. Workers in the public service (adjusted odds ratio [aOR] = 1.29, 95% confidence interval [CI] 1.14-1.45) and information technology (aOR = 1.38, 95% CI 1.20-1.58) industries were more likely to use the app than were those in the manufacturing industry. In contrast, app usage was less common among workers in the retail and wholesale (aOR = 0.87, 95% CI 0.76-0.99) and food/beverage (aOR = 0.81, 95% CI 0.70-0.94) industries, but further adjustment for company size attenuated these associations. Workers at larger companies were more likely to use the app. Compared with permanent employees, the odds of using the app were higher for managers and civil servants but lower for those who were self-employed. CONCLUSIONS Downloading of COCOA among Japanese workers was insufficient; thus, the mitigating effect of COCOA on the COVID-19 pandemic is considered to be limited. One possible reason for the under-implementation of the contact tracing app in the retail and wholesale and food/beverage industries is small company size, as suggested by the fully adjusted model results. An awareness campaign should be conducted to promote the widespread use of the contact tracing app in these industries.

Abstract
OBJECTIVE To examine the relationship between the physical work environment and work function while working from home (WFH). METHODS A cross-sectional study was conducted. Data from 5760 workers who worked from home at least 1 day a month were analyzed. The physical work environment while WFH was used as an exposure factor. The presence of work functioning impairment was measured using Work Functioning impairment Scale (WFun). Mixed-effects logistic regression was used with the prefecture of residence as a random effect. RESULTS Work functioning impairment was significantly associated with a "No" response to recommended environments. The highest odds ratio (OR) of work functioning impairment was associated with a "No" response to "There is enough light to do my work" (adjusted odds ratio [aOR]: 2.02, 95% confidence interval [CI]: 1.73 to 2.35, P < 0.01). CONCLUSIONS Improving work environments may prevent negative health effects and improve productivity while WFH.

Participants' telecommuting preference and frequency during the COVID-19 pandemic were determined using a questionnaire. Psychological distress was assessed using Kessler 6 (K6). RESULTS Among participants who did and did not prefer to telecommute, those who telecommuted four or more days per week had an OR of psychological distress of 0.67 (P < 0.001) and 1.87 (P = 0.001), respectively, compared with those who rarely telecommuted. CONCLUSIONS The association between telecommuting and psychological distress differs depending on telecommuting preference.

Abstract
Background This study aimed to examine the association between overtime work and the frequency of preventive dental visits among workers in Japan. Methods A self-administered questionnaire was completed by 14,847 daytime-workers. We used a logistic regression model stratified by sex and age and adjusted for marital status, occupation, education, and oral status to investigate the association between overtime work hours and the frequency of preventive dental visits. Results In total 1037 men (9.3%) and 511 women (13.9%) attended quarterly preventive dental visits, and 2672 men (23.9%) and 1165 women (31.8%) attended annual preventive dental visits. Overtime work was statistically significantly associated with quarterly preventive dental visits among men aged 50–59 years, with adjusted odds ratios (aOR) and 95% confidence intervals (CI) of 0.73 (0.56–0.95), 0.75 (0.54–1.04), and 0.55 (0.34–0.90) for < 20, 20–39, and ≥40 h overtime/month, respectively. No such trends were observed for men aged < 50 years and women of all ages. Overtime work of < 20, 20–40, and ≥40 h overtime/month was statistically significantly associated with annual preventive dental visits among men aged 40–49 years (aOR [95%CI]: 0.76 [0.61–0.95], 0.84 [0.65–1.09], and 0.72 [0.51–1.00], respectively) and 50–59 years (aOR [95%CI]: 0.75 [0.61–0.91], 0.76 [0.59–0.97], and 0.63 [0.45–0.88], respectively). No such trends were observed in men < 40 years and women of all ages. Conclusions Our study revealed associations between overtime and preventive dental visits among male workers aged in their 40s and 50s.

Abstract
OBJECTIVES Little is known about workplace measures against coronavirus disease 2019 (COVID-19) in Japan during the winter of 2020, especially in micro-, small-, and medium-sized enterprises (MSMEs). This study aimed to provide an overview of the current situation of anti-COVID-19 measures in Japanese enterprises during the winter, considering company size. METHODS This study was an Internet-based nationwide cross-sectional study. Individuals who were registered as full-time workers were invited to participate in the survey. Data were collected using an online self-administered questionnaire in December 2020. The chi-squared test for trend was performed to calculate the P-value for trend for each workplace measure across company sizes. RESULTS For the 27 036 participants, across company sizes, the most prevalent workplace measure was encouraging mask wearing at work, followed by requesting that employees refrain from going to work when ill and restricting work-related social gatherings and entertainment. These measures were implemented by approximately 90% of large-scale enterprises and by more than 40% of micro- and small-scale enterprises. In contrast, encouraging remote working was implemented by less than half of large-scale enterprises and by around 20% of micro- and small-scale enterprises. There were statistically significant differences in all workplace measures by company size (all P < .001). CONCLUSIONS We found that various responses to COVID-19 had been taken in workplaces. However, some measures, including remote working, were still not well-implemented, especially in smaller enterprises. The findings suggest that occupational health support for MSMEs is urgently needed to mitigate the current wave of COVID-19.

Abstract
Background: The current coronavirus (COVID-19) pandemic has had large impacts on society, including people practicing social distancing. This behavioral response has increased loneliness. Loneliness not only increases the risk of psychiatric disorders, but also affects occupational mental health. To avoid the negative effects of isolation, it is important to have social contact with other people, especially family members. Employment and economic instability caused by COVID-19 may have also affected family relationships. It is important to understand the association between family relationships and loneliness in workers under the pandemic. Methods: We collected usable data from 27,036 Japanese workers who completed an online survey during the COVID-19 pandemic. Participants were asked how long they spend with members of their family during mealtimes or at home, and if they experienced loneliness; the latter was assessed by a single question. Other questions included whether participants lived with their spouse, or with someone in need of care. To estimate the odds ratios (ORs) of time with family associated with loneliness we used a multilevel logistic model nested in the prefecture of residence, with adjustments for age, sex, marital status, presence of a cohabitant requiring care, equivalent income, educational level, number of employees in the workplace, frequency of remote work, availability of someone for casual chat, smoking, drinking, time for leisure interests, and cumulative rates of COVID-19 in the prefecture. Results: Ten percent (2,750) of the 27,036 participants reported loneliness. The survey showed a significant negative correlation between time spent with family and loneliness (p < '0.001): participants who spent more time with family were less likely to feel loneliness. In addition, not living with a spouse and living with someone in need of care were associated with loneliness (not living with a spouse: p < 0.001; living with someone in need of care: p < 0.001). Conclusion: Loneliness under COVID-19 pandemic conditions was negatively associated with time spent with family members, with the converse result found for participants cohabiting with someone in need of care. These associations suggest the potential value of changes to working practices and interventions to combat loneliness.

Abstract
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.

Abstract
OBJECTIVES The health effects of telework, which was introduced extensively in the immediate context of the COVID-19 pandemic crisis in Japan, on teleworkers, their families, and non-teleworkers, are unknown. Accordingly, we developed a rapid health impact assessment (HIA) to evaluate positive and negative health effects of telework on these groups and recommended easily implementable countermeasures. METHODS Immediately after an emergency was declared in Japan, we implemented a rapid, five-step HIA. We screened and categorized health effects of telework for the three above-mentioned groups, extracting their content, directionality, and likelihood. Following a scoping exercise to determine the HIA's overall implementation, five experienced occupational health physicians appraised and prioritized the screened items and added new items. We outlined specific countermeasures and disseminated the results on our website. A short-term evaluation was conducted by three external occupational health physicians and three nurses. RESULTS Following screening and appraisal, 59, 29, and 27 items were listed for teleworkers, non-teleworkers, and family members of teleworkers, respectively, covering work, lifestyle, disease and medical care, and home and community. Targeted countermeasures focused on the work environment, business management, communications, and lifestyles for teleworkers; safety and medical guidelines, work prioritization, and regular communication for non-teleworkers; and shared responsibilities within families and communication outside families for family members of teleworkers. CONCLUSION The HIA's validity and the countermeasures' practical applicability were confirmed by the external evaluators. They can be easily applied and adapted across diverse industries to mitigate the wider negative effects of telework and enhance its positive effects.

Abstract
OBJECTIVE Due to the COVID-19 pandemic, telecommuting has become a new way of working that has not only changed individuals' work, but also their health and lifestyle. We examined the relationship between telecommuting frequency and unhealthy dietary habits among Japanese workers. METHODS A total of 33,302 workers completed an Internet survey about telecommuting and dietary habits. Data from 13,468 office workers who telecommuted were analyzed. Telecommuting frequency during the COVID-19 pandemic was extracted from a questionnaire. The odds ratios (ORs) of four types of dietary habits, namely, skipping breakfast, solitary eating, lower meal frequency, and meal substitution associated with telecommuting frequency were estimated using multilevel logistic regression nested in the prefecture of residence to control for differences in residential area. RESULTS The multivariate OR of skipping breakfast was 1.15 (95% CI: 1.03-1.29, p = .013) for participants who telecommuted in excess of four days per week compared to those who rarely telecommuted. Similarly, the OR of solitary eating, lower meal frequency and meal substitution were 1.44 (95% CI: 1.28-1.63, p < .001), 2.39 (95% CI: 1.66-3.44, p < .001), and 1.26 (95% CI: 1.04-1.51, p = .015) for those who telecommuted in excess of four days per week compared to those who rarely telecommuted. There was a statistically significant increase in the dose-response trend in ORs of solitary eating (p for trend <.001), lower meal frequency (p for trend <.001), and meal substitution (p for trend = .001) with increasing telecommuting frequency. CONCLUSION Telecommuters may develop unhealthy dietary habits, indicating the need for strategies to help telecommuters manage their nutrition and diet.

Abstract
OBJECTIVES This study examined the relationship between the status of infection control efforts against COVID-19 in the workplace and workers' mental health using a large-scale Internet-based study. METHODS This cross-sectional study was based on an Internet monitoring survey conducted during the third wave of the COVID-19 epidemic in Japan. Of the 33 302 people who participated in the survey, 27 036 were included in the analyses. Participants answered whether or not each of 10 different infection control measures was in place at their workplace (eg, wearing masks at all times during working hours). A Kessler 6 (K6) score of ≥13 was defined as mild psychological distress. The odds ratios (ORs) of psychological distress associated with infection control measures at the workplace were estimated using a multilevel logistic model nested in the prefectures of residence. RESULTS The OR of subjects working at facilities with 4 or 5 infection control measures for psychological distress was 1.19 (95% confidence interval [CI]: 1.05-1.34, P = .010), that in facilities with 2 or 3 infection control measures was 1.43 (95% CI: 1.25-1.64, P < .001), and that in facilities with 1 or no infection control measures was 1.87 (95% CI: 1.63-2.14, P < .001) compared to subjects whose workplaces had ≥6 infection control measures. CONCLUSION Our findings suggest that proactive COVID-19 infection control measures can influence the mental health of workers.

Abstract
OBJECTIVES The aim of the present study was to clarify the relationship between work functional impairment levels and three coping behaviors of workers with low back pain, which were about seeking medical attention, taking over-the-counter drugs, and taking self-care. METHODS We conducted a cross-sectional study on 14 Japanese companies in 2016. Work function impairment was measured using the Work Functioning Impairment Scale. Logistic regression analyses were conducted for the three coping behaviors and odds ratios (ORs) calculated for work functional impairment levels. RESULTS We analyzed 2232 subjects; 226 were women and 790 worked on production lines. 688 workers had sought medical attention, 436 had taken over-the-counter medication, and 1225 had engaged in self-care. Those seeking medical attention were associated with severe work function impairment compared with no work function impairment (adjusted OR = 2.84, 95% confidence interval: 1.82-4.45, p < .001). We observed a trend for the association between over-the-counter drug use with high levels of work function impairment (adjusted OR: 1.19 for low, 1.35 for moderate, 1.65 for severe). There was no apparent relationship between self-care and the degree of work functional impairment. CONCLUSION In workers with low back pain, severe work functional impairment may promote medical attention and over-the-counter medication use, but it would not encourage self-care, such as stretching or exercise. Therefore, workplaces need to provide special support to help them take care of themselves. Therefore, it is desirable to provide good support for self-care in the workplace.

Abstract
Study objectives This cross-sectional study analyzed the effect of treatment with hypnotics for sleep disorders, particularly insomnia, on daytime work functioning by phase of treatment in Japanese workers. Methods Subjects were respondents (n = 36,375) to a questionnaire survey conducted in 2015 to assess work functioning impairment in 15 companies in Japan. The questionnaire results were analyzed together with the respondents’ healthcare data extracted from public health insurance claims. Work functioning impairment was measured using the Work Functioning Impairment Scale (WFun). The status of treatment for insomnia was determined using data on diseases and prescribed drugs extracted from health insurance claims from the past 16 months. The odds ratio of severe work functioning impairment according to on-treatment duration and off-treatment duration was estimated using logistic regression analysis. Results The risk of severe work functioning impairment was significantly higher in subjects with insomnia who were being treated with hypnotics for 1 month or longer compared to non-insomnia subjects. This increased risk tended to be reduced with longer on-treatment duration. For subjects who had previously received hypnotics treatment for insomnia, the risk of severe work functioning impairment was significantly increased in all subgroups stratified by time from discontinuation of the prescription. This increased risk tended to be reduced with longer off-treatment duration. Conclusions Workers who are or were receiving hypnotics to treat insomnia may have a higher risk of daytime functioning impairment. Those with protracted insomnia require careful assessment of the risks and benefits of prescription hypnotics.

Abstract
This study investigated the association between the duration of pharmacotherapy treatment for depression, or discontinuation from treatment, and work functioning impairment. This was a retrospective cohort study examining 30,409 workers. Work functioning impairment was assessed using a questionnaire, and treatment status was assessed using medical claims data. Odds ratios (ORs) of workers with severe work functioning impairment compared with healthy workers (control group) were calculated using logistic regression analysis. Continuous medical treatment was associated with severely impaired work functioning regardless of treatment period [continuous medical treatment; 4 months <: OR = 3.2, 4 months ≥, 10 months <: OR = 2.6, 10 months ≥, 14 months <: OR = 2.3, 14 months ≥, 16 months <: OR = 2.3, which are all statistically significant (p < 0.05)]. Workers who initially received pharmacotherapy treatment but discontinued in < 11 months had a significantly higher OR (treatment discontinuation period; 3 months <: OR = 2.3, 3 months ≥, 8 months <; OR = 2.0, 8 months ≥, 11 months <; OR = 3.0), while those who discontinued at ≥ 11 months did not (OR = 1.4, 95% CI 0.6-3.5). The sensitivity analysis excluding participants with at least one psychiatric comorbidity other than depression did not change the final result. It is important for the occupational health practitioners and attending psychiatrists to follow up in cooperation with each other, paying attention to the decrease in work functioning in addition to the symptoms.

Abstract
Objectives The objective of this study was to estimate a risk of cardiovascular and cerebrovascular diseases for each worker and to determine whether this risk is associated with the incidence and costs of presenteeism, absenteeism, and medical/drug treatments. Methods Established risk equations were used to estimate the 10‐year probability of developing coronary artery disease and ischemic stroke in male workers aged 40‐65 years who were recruited from four pharmaceutical companies in Japan. The incidence of presenteeism was defined as existence of presenteeism for the past a month, and the incidence of absenteeism was defined as existence of sick‐leave for the past three months by a self‐administered questionnaire. Each cost was calculated based on the human capital method. Data on medical/drug treatments were collected from health insurance claims. Results The risks were calculated for 6047 workers. Individuals at moderate and high risk of coronary artery disease had a significantly higher rate of presenteeism and absenteeism than workers at low risk. Workers at moderate and high risk of ischemic stroke also had a significantly higher rate of presenteeism and absenteeism than workers at low risk. Mean costs for absenteeism and medical/drug treatments increased with the risk of developing coronary artery disease or ischemic stroke, while costs for presenteeism did not. Conclusions To prevent the costs of presenteeism, workers not only at high risk but also at low and moderate risk of developing cardiovascular and cerebrovascular diseases should receive health care services.

Abstract
Background:The 2019 ACR/EULAR classification criteria for IgG4-RD have recently been published1). In the criteria, patients with an inclusion criteria score of >20 without exclusion criteria are classified as having IgG4-RD.Objectives:To validate the 2019 ACR/EULAR classification criteria for IgG4-RD in a Japanese kidney disease cohort.Methods:The study involved Japanese patients diagnosed as having kidney disease between April 2012 and May 2019, for whom sufficient clinical information and data on serum IgG4 values and/or immunohistological staining for IgG4 in renal biopsy samples were known. These patients were classified as having IgG4-RKD or non-IgG4-RKD (mimickers) based on the 2019 ACR/EULAR classification criteria for IgG4-RD, and the results were evaluated by expert opinion.Results:Among 105 included patients, the expert panel diagnosed 55 as having true IgG4-RKD and 50 as mimickers. The final diagnoses among the mimickers were vasculitis (n=11), idiopathic tubulointerstitial nephritis (TIN) (n=5), drug-induced TIN (n=5), Sjögren’s syndrome (n=4) and others. Among the 55 true IgG4-RKD patients, 4 had exclusion criteria, and 50 of the remaining 51 had an inclusion criteria score of ≥20 points (sensitivity 90.9%). On the other hand, 49 of the 50 mimickers were classified as having non-IgG4-RKD (specificity 98.0%) (Table 1).Table 1.General characteristics and prevalence of individual items of true IgG4-RKD and non-IgG4-RKD (mimicker)IgG4-RKD(true IgG4-RKD)(n=55)Non-IgG4-RKD(mimicker)(n=50)PAge at diagnosis,mean ±SD (years)69.9 ± 9.456.7 ± 17.4<0.001Male (%)76.4440.001Elevated serum IgG454/55 (98.2%)18/50 (36.0%)<0.001Serum IgG4 (mg/dl), mean±SD1028 ± 796226 ± 261<0.001Dense IgG4+Plasma cells (>10/hpf) in the kidney biopsy48/51 (94.1%)13/40 (32.5%)<0.001Storiform fibrosis in the kidney biopsy28/51 (54.9%)3/50 (6%)<0.001Hypocomplementemia39/55 (70.1%)7/42 (16.7%)<0.001Renal pelvis thickening/soft tissue5/55 (9%)1/50 (2%)0.20Bilateral renal cortex low-density areas29/55 (52.7%)7/50 (14.0%)<0.001Exclusion criteria present4/55 (7.3%)22/50 (44%)<0.001Total inclusion criteria points >20 without exclusion criteria50/55 (90.9%)1/50 (2%)<0.001Conclusion:The 2019 ACR/EULAR classification criteria for IgG4-RD showed good agreement with expert classification in this Japanese kidney disease cohort.References:[1] Wallace ZS, et al.

Abstract
OBJECTIVES Swallowing function is critical for continuing oral feeding to prevent frailty in older adults. In this study, we investigated the impact of tongue pressure and pulmonary function on the nutritional status of older adults. DESIGN, SETTING, PARTICIPANTS This cross-sectional study was conducted in Kitakyushu, Japan from August 2017 to November 2018. Fifty-two residents aged >65 years of age from three nursing care insurance facilities in Kitakyushu City, Japan were recruited. MEASUREMENTS Oral health status, swallowing function, nutritional status using a mini nutritional assessment short form (MNA-SF), cognitive function, activities of daily living, peak expiratory flow rate (PEFR) for pulmonary function, and tongue pressure were assessed. The associations between nutritional status and the above factors were analysed using a logistic regression model. RESULTS Participants were divided into two groups: well-nourished group (MNA-SF ≤12) and undernutrition group (MNA-SF <12). Multivariate logistic regression analysis revealed that the correlations of PEFR [odds ratio (OR) = 0.23, 95% confidence interval (CI) = 0.23-0.89 p=0.033) and tongue pressure (OR = 0.88, 95% CI = 0.88-0.99, p=0.029) remained significant even after adjustment with possible confounders. CONCLUSION Maximum tongue pressure and PEFR in older adults were significantly associated with their nutritional status. These findings suggest that maintaining oral and pulmonary function may be a preventive factor against a decrease in the nutritional status of older frail adults.
