Background: Workplaces are an important setting to deliver programs to reduce risk factors for noncommunicable diseases (NCDs). To help decision makers understand the most current and relevant evidence regarding effectiveness of workplace programs, we conducted an umbrella review to present a comprehensive synthesis of the large volume of literature.

Methods: Systematic reviews of workplace interventions targeting primary risk factors for NCDs-unhealthy diet, insufficient physical activity, overweight/obesity, tobacco use, and/or excessive alcohol use-published since 2010 were sourced. For each risk factor, reviews were categorized by intervention type and quality. The most recent, high-quality review was included for each intervention type. Evidence for the effectiveness of each intervention type was then broadly classified based on the review summary findings.

Results: Twenty-one reviews were included. Most reviews focused on diet (n = 5), physical activity (n = 7), or obesity (n = 9) interventions, with fewer targeting alcohol (n = 2) or tobacco (n = 2) use. Reviews of interventions focusing on individual behavior (such as education or counseling) were most common. Across diet, obesity, physical activity, and tobacco use, multicomponent interventions were consistently likely to be classified as "likely effective." Motivational interviewing and broad health promotion interventions were identified as "promising" for alcohol use.

Conclusion: This umbrella review identified that multicomponent workplace interventions were effective to reduce NCD risk factors. There is a gap around interventions targeting alcohol use as most syntheses lacked enough studies to draw conclusions about effectiveness. Exploring the impact of interventions that utilize policy and/or environmental strategies is a critical gap for future research.

Background: Since the Fukushima Daiichi nuclear power plant (FDNPP) accident in 2011, measures have been taken to address occupational health risks, such as heat illness and infectious diseases, and ensure fitness for duty with the Tokyo Electric Power Company and its contractors. However, with the decommissioning operations set to span several decades and an aging workforce, there arose a need for proactive occupational health strategies that not only addressed these risks but also promoted employee health and created a comfortable work environment. With the Japanese government's promotion of health and productivity management (HPM) for corporations, an HPM-based initiative was launched at the FDNPP in 2019.

Case: We designed an HPM questionnaire tailored to the unique conditions at the FDNPP for contractors in 2019. Subsequently, we adjusted the questionnaire annually in light of evolving societal contexts and insights derived from contractors' feedback. This initiative also involved the annual recognition of outstanding contractors. These efforts have led to a steady increase in the number of contractors participating in the HPM survey, with respondents' scores continually improving. We also emphasized dissemination of HPM practices from contractors to their subcontractors due to the complex subcontracting structure at FDNPP, and our results showed that more contractors have been extending these efforts to their subcontractors.

Conclusions: Our findings suggest that individual contractors are steadily enhancing their HPM efforts. We are committed to continually offering support to advance HPM throughout the FDNPP.

Background: Stay-at-home orders during the COVID-19 global pandemic created unprecedented challenges for workers whose work was transferred to the home setting. Little is presently known about the benefits and the challenges associated with global remote work on well-being and mental health, work-life balance, job satisfaction, productivity, home office adaptability, and gender equality.

Methods: A scoping review of PubMed/Medline was undertaken in October 2021 to better understand these broad dimensions associated with remote worker health, well-being, and the home office workspace. The review focused on white-collar workers who undertook remote work during each of the lockdown waves from March 2020 to 2021.

Results: A total of 62 studies were included in the review, which spanned Asia, North America, South America, and Europe. Overall, workers seemed to enjoy remote work, but productivity varied. The main setbacks associated with remote work included feelings of isolation and loneliness, which negatively influenced well-being. Social support from management and contact with colleagues mitigated this. Leadership style also influenced remote worker well-being. Overall, women suffered from lower levels of remote work well-being and productivity, especially if they had children. The home office and its adaptability were integral for successful remote work. Work-life balance was affected in some workers who struggled with heavier workloads or family duties.

Conclusions: To promote well-being and successful remote work, isolation and loneliness should be reduced through greater contact with colleagues and managers. Managers should promote family friendly policies that may support work-life balance and reduce gender inequities in remote work.

There is a wide body of research on the effects of social media use on mental health, particularly focusing on young people. However, very little is known about the mental health of social media influencers (SMIs), who also tend to be quite young. This is of growing significance as more of our daily lives is conducted online, and in the context of poor population mental health globally, which declined further as a result of the COVID-19 pandemic. We therefore set out to review the mental health of SMIs and, in the absence of literature on SMIs, drew on other similar but more traditional occupational groups, such as the self-employed, to draw conclusions and identify directions for future research.

Objectives: This study aimed to examine the relationship between physical activity (PA) and locomotive syndrome (LS) among young and middle-aged Japanese workers.

Methods: This cross-sectional study included 335 participants from a company in Kumamoto, Japan. LS was evaluated using the 25-question Geriatric Locomotive Function Scale (GLFS-25); a GLFS-25 score ≥7 was defined as LS. Weekly PA was measured using the International Physical Activity Questionnaire. Work-related PA (time spent sitting, standing, walking, and strenuous work per day) and sedentary breaks were measured using a Work-related Physical Activity Questionnaire. Screen usage (television [TV], smartphones, tablets, and personal computers) during leisure time was recorded. The association between PA and LS was examined using a multivariate logistic regression analysis adjusted for age, sex, body mass index, history of musculoskeletal disorders, cancer, stroke, occupation, employment type, work time, shift system, employment status, and body pain.

Results: A total of 149 participants had LS. Fewer sedentary breaks during work (>70-minute intervals, odds ratio [OR] = 2.96; prolonged sitting, OR = 4.12) and longer TV viewing time (≥180 minutes, OR = 3.02) were significantly associated with LS. In contrast, moderate PA (OR = 0.75) was significantly associated with a lower risk of LS.

Conclusions: Fewer sedentary breaks during work and longer TV viewing time could increase the risk of LS in young and middle-aged Japanese workers.

Objectives: Perceived organizational support (POS) represents the extent to which employees believe their organization values their contributions and well-being. Although higher POS is associated with increased work engagement and learning motivation, the intricacies of this relationship, especially the mediation by occupational future time perspective (OFTP), are not well understood.

Methods: We conducted an online survey of 2046 working individuals aged 20-69 to assess the relationships between POS and 2 outcome variables, learning goal orientation (LGO) and work engagement, with multiple regression analyses for all ages and in the younger age group (under 45). Then, the mediating effects of focus on opportunity (FOO)-a primary component of OFTP-on these relationships were examined.

Results: Of 2046 participants, 887 were younger than 45 years. Younger participants, predominantly more educated and inclined toward professional jobs, exhibited higher LGO but lower work engagement compared with their older counterparts. POS showed positive correlations with LGO, and FOO significantly mediated the relationship, especially in the young group. Furthermore, a positive relationship between POS and work engagement was noted, with FOO as a partial mediator.

Conclusions: POS correlates positively with both LGO and work engagement across various age demographics, with FOO critically mediating this relationship. To enhance employee engagement and learning motivation, organizations should emphasize bolstering both POS and FOO.

Objectives: Remote work (ie, teleworking) may adversely affect physical activity (PA) among workers, but no strategies have been effectively implemented to address this issue. We aimed to test whether a multicomponent intervention program could promote the PA of remote workers.

Methods: This study was an 8-week pilot open-label randomized controlled trial. Fifty-one participants (19 women) aged 23-58 years were recruited via an information technology company in Tokyo, Japan, and randomly assigned to the control (n = 26) or intervention (n = 25) group. The intervention group was provided a multicomponent intervention that comprised individual (lecture, print material, goal setting, feedback, and posters), sociocultural (supportive atmosphere and team building), and organizational (encouraging message from an executive) strategies. The control group only received posters. The primary outcome was an 8-week change in objectively measured moderate-to-vigorous PA (MVPA). The secondary outcomes were changes in light PA, moderate PA, vigorous PA, steps, and sedentary time. We also conducted subdomain analyses divided into working and nonworking days.

Results: No significant difference was observed in MVPA changes between the 2 groups. However, the intervention group showed significant improvement in light PA by +14.0 min/d (95% CI, 1.7-26.2). Subdomain analyses also showed no significant differences in MVPA changes between the 2 groups. However, MVPA in the intervention group significantly increased by +9.4 min/d (95% CI, 2.5-16.2) on working days.

Conclusions: The present multicomponent intervention was feasible for remote workers, although some revisions are necessary to enhance the effect size.

Objectives: Translating research into practice is often a goal for evidence-based organizational researchers to help improve workplace conditions and worker well-being. Improving worker well-being can be achieved by using empirical evidence to inform organizational interventions. However, despite the well-established intervention literature, practitioners appear not to appreciate fully how research findings can inform real-world practice. Using our understanding about workplace safety and health issues, we proposed that employers themselves could undertake interventions that focus on building psychosocial safety climate (PSC), an essential organizational climate that protects and promotes the psychological well-being of workers.

Methods: Here we present 2 case studies to illustrate strategies that improve psychosocial safety and to increase our understanding about how interventions help improve PSC over time. Case Study 1 was conducted in an Australian public organization and Case Study 2 was in an international private organization. We collected survey data using the PSC-12 scale, to assess the level of PSC of the organization before and after the intervention, and details of the intervention and other initiatives for promoting employees' psychological health.

Results: Our evaluation supported the proposition that interventions that combine organizational-level and individual-level (and the interface between the two) approaches with a focus on the core elements of PSC (such as commitment, priority, communication, and participation) improve an organization's PSC over time.

Conclusions: The research not only elucidates important practical implications for organizations trialing new psychosocial safety initiatives, but also makes an important contribution to theory in work stress intervention on best practice and principles to build a psychologically healthy work context.

Objectives: Although studies have shown that work-related musculoskeletal disorders (WMSDs) are common and continue to be a major source of disability and work time loss, there are few reports about elbow WMSDs. The aim of this study was to explore the prevalence and associated factors of elbow WMSDs.

Methods: The valid questionnaires of 57501 workers from 15 different industries nationwide were collected and the c2 test and logistic regression analysis were applied to reveal the prevalence and risk factors of elbow WMSDs.

Results: The findings indicated that the overall prevalence of elbow WMSDs among workers was 7.3%. However, the prevalence of elbow WMSDs in toy manufacturing was 21.3%, which was significantly higher than that in other industries (P < .05). Logistic regression analysis showed that age 40 and above, married, very poor health, left-handedness, lifting weights (more than 20 kg each time), work requiring upper limb or hand force, work in an uncomfortable position, repetitive operations within 1 minute, using vibrating tools, work involving cold, cool draughts, or temperature changes, work being completed in the same workshop, work being done outdoors, frequent dealings with customers, 2 shifts, often working overtime, staff shortage, and often working for colleagues were risk factors for elbow WMSDs. A higer education level, monthly income, and enough rest time were protective factors for elbow WMSDs.

Conclusions: Toy manufacturing is a high-risk industry for elbow WMSDs. Promotion of education about ergonomics should be strengthened, and workers' ergonomics awareness should be improved to reduce the impact of WMSDs.
