Obesity occurs less frequently in Japanese than in various other ethnic populations. A person with abnormal glucose tolerance is often found to have one or more of the other cardiovascular disease risk factors, such as obesity, hypertension and hyperlipidemia. This clustering has been labeled as metabolic syndrome (WHO, 1998). It was suggested that Japanese, categorized as having normal weight (BMI of less than 25.0), as defined by the WHO (2000), have an increasing tendency toward metabolic syndrome. Our objective was to analyze metabolic syndrome in “Overweight” with BMI of 23.0-24.9 in Japanese workers, and to assess the suitability for Asians of the Regional Office for the Western Pacific Region of WHO criteria pertaining to obesity (WPRO criteria, 2000). We conducted a cross-sectional study in the workplace setting and investigated the relationship between BMI classification based on WPRO criteria and metabolic syndrome by gender and age group (18-44 yr vs. 45-60 yr). Three hundred seventy-nine men and 432 women Japanese workers participated in this study. BMI were categorized as 20% “Overweight” (23.0-24.9 BMI), 20% “Obese I” (25.0-29.9 BMI) and 2% “Obese II” (over 30.0 BMI), based on WPRO criteria. Graded increases in BMI were positively associated with body fat percentage, waist circumference, hip circumference and waist/hip ratio in both genders and age groups. A progressively increasing BMI category in the elder group aged 45-60 yr in both genders was positively related with parameters constituting metabolic syndrome. Graded increases in BMI classes in elder workers based on WPRO criteria were positively associated with prevalence of metabolic syndrome, and “Overweight” elder women had significantly higher prevalence of metabolic syndrome. The present investigation, based on the increasing risks of “Overweight” with a BMI of 23.0-24.9, suggests that WPRO criteria are suitable for Japanese workers aged over 45 yr.

Objective: To perform a systematic review of randomized controlled trials (RCTs) on the efficacy of therapeutic exercises for workers suffering from rotator cuff (RC) tendinopathy.Methods: A literature search in four bibliographical databases (Pubmed, CINAHL, EMBASE, and PEDro) was conducted from inception up to February 2015. RCTs were included if participants were workers suffering from RC tendinopathy, the outcome measures included work-related outcomes, and at least one of the interventions under study included exercises. The methodological quality of the studies was evaluated with the Cochrane Risk of Bias Assessment tool.Results: The mean methodological score of the ten included studies was 54.4% ± 17.2%. Types of workers included were often not defined, and work-related outcome measures were heterogeneous and often not validated. Three RCTs of moderate methodological quality concluded that exercises were superior to a placebo or no intervention in terms of function and return-to-work outcomes was observed. No significant difference was found between surgery and exercises based on the results of two studies of low to moderate methodological quality. One study of low methodological quality, comparing a workplace-based exercise program focusing on the participants' work demands to an exercise program delivered in a clinical setting, concluded that the work-based intervention was superior in terms of function and return-to-work outcomes.Conclusion: There is low to moderate-grade evidence that therapeutic exercises provided in a clinical setting are an effective modality to treat workers suffering from RC tendinopathy and to promote return-to-work. Further high quality studies comparing different rehabilitation programs including exercises in different settings with defined workers populations are needed to draw firm conclusions on the optimal program to treat workers.

Objectives: The informal sector is the dominant area of employment and the economy for any developing country including Bangladesh. The cost of productivity loss due to absence from work or presenteeism with illness has rarely been examined in the Bangladesh context. This current study, therefore, attempted to examine the impact of ill health of informal sector workers on labor productivity, future earning, and healthcare-related expenditure. Methodology: A cross-sectional survey was conducted among three occupational groups of informal workers (rickshaw pullers, shopkeepers and restaurant workers) that were generally found in all urban areas in Bangladesh. A total of 557 informal workers were surveyed for this study. Results: Most of the respondents (57%) reported that they had been affected by some type of illness for the last six months. The overall average healthcare expenditure of informal workers was US$48.34, while restaurant workers expended more (US$53.61). Self reported sickness absenteeism was highest (50.37days) in the case of shop keepers, followed by rickshaw pullers (49.31 days), in the last six months. Considering the income loss due to illness in the past six months, the rickshaw pullers were exposed to the highest income loss (US$197.15), followed by the shop keepers (US$151.39). Conclusions: Although the informal sector contributes the most to the economy of Bangladesh, the workers in this sector have hardly any financial protection. This study provides critical clues to providing financial and social protection to informal sector workers in Bangladesh.

Objectives: This article aims to review the current prevalence rate of latex allergy among healthcare workers, susceptible patients, and the general public and to investigate why latex is still a ubiquitous occupational health hazard. Methods: Scientific publications on PubMed, particularly those published within the last five years, and current regulations from agencies such as Food and Drug Administration (FDA) were reviewed. Consumer and commercial products that may contain latex were also surveyed. Results: Approximately 12 million tons of natural rubber latex is produced annually and is widely used to manufacture millions of consumer and commercial products. Only limited number of latex-derived products have been approved and regulated by government agencies, such as FDA, whereas the majority of finished products do not label whether they contain latex. Owing to millions of unidentifiable products containing latex and many routes for exposure to latex, preventing contact with latex allergens and reducing the prevalence of latex allergy are more difficult than expected. Reported data suggest that the average prevalence of latex allergy worldwide remains 9.7%, 7.2%, and 4.3% among healthcare workers, susceptible patients, and general population, respectively. Conclusions: Latex-derived products are ubiquitous, and latex allergy remains a highly prevalent health risk in many occupations and to the general population. Developing alternative materials and increasing the ability to identify and label latex-derived products will be practicable approaches to effectively control the health risks associated with latex.

Objectives: Burnout is a psychological consequence of prolonged work stress. Studies have shown that it is related to physical and mental disorders. The safety outcomes of burnout have been studied to a lesser extent and only in the work context. This study explored the effect of burnout on future severe injuries regardless of their context. Methods: A total of 10 062 forest industry employees (77% men, 63% manual workers) without previous injuries participated in 1996 or 2000 in the “Still Working” study examining the work-related antecedents of health and mortality. Burnout was assessed using the Maslach Burnout Inventory-General Survey. Injuries leading to death or hospitalization were regarded as severe. We extracted such injuries from independent national registers. The relationship between burnout and new injuries was analyzed using Cox proportional regression. The analyses were adjusted for age, sex, marital status, and occupational status. Results: There were 788 new injuries over eight years. Injuries were more common among male and manual workers. After adjustments, each one-unit increase in the burnout score was related to a 9% increase in the risk of injury (95% confidence interval 1.02-1.17). Experiencing symptoms at least monthly was related to a 1.18-fold adjusted injury risk (95% CI 1.02-1.36). Of the subscales of burnout, exhaustion and cynicism but not lack of professional efficacy predicted injuries after adjustments. Conclusions: In addition to mental and physical disorders, burnout predicts severe injuries. Developing work conditions and optimizing workload may enhance safety and decrease health expenses related to all injuries.

Background The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. Objective The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for increased asthma severity. Methods We retrospectively reviewed the clinical charts of 72 patients who received a diagnosis of allergic occupational asthma, with or without associated occupational rhinitis. Results Our findings suggested that persistent asthma tended to be more common in subjects with associated occupational asthma and rhinitis, and occupational asthma severity was associated with occupational rhinitis severity. Moderate-severe persistent occupational rhinitis is a risk factor for persistent occupational asthma. Conclusions We demonstrated, for the first time in the occupational setting, a significant association between occupational rhinitis and asthma severity.

Objective: The aim of this study was to examine the relationship between age and the lost-time workers’ compensation claims in British Columbia, Canada, over three time periods (1997-98, 2001-02 and 2005-06). We examined if the relationship between age and risk of lost-time claims is consistent over time and for different nature of injury categories. Methods: Secondary analyses of lost-time workers’ compensation claims combined with estimates of person-years of exposure generated from the Canadian Labour Force Survey were performed. Analyses examined the relationship between age and claim risk using sex-stratified regression models, adjusting for time period, occupational characteristics and whether the claimant was employed in the goods or service industry. Multiplicative interaction terms were used to examine if the relationship between age and lost-time claim risk changed over time. Seven separate regression models were generated to explore the variation in the effect of age across nature of injury groups. Results: We observed important differences in the relationship between age and risk of injury depending on the nature of injury examined. A negative relationship was observed between age and lost-time claims for open wounds, while a positive relationship was observed for traumatic injuries to bones, nerves and the spinal cord. We found no evidence that the relationship between age and risk of lost-time claims changed over time periods. Conclusions: The association between age and risk of lost-time claims depends on the nature of injury under investigation. We found no evidence that the relationship between age and overall lost-time claim risk has changed over time in British Columbia.

Objectives: The Japanese government launched a new occupational health policy called the Stress Check Program. This program mandates that all workplaces with 50 or more employees conduct the Stress Check Program for workers at least once a year. This article gives a brief overview and critical review of the program. Methods: We reviewed relevant laws, guidelines, and manuals, as well as the policy development process. The policy and the components of the program were compared using available scientific evidence and trends in the management of psychosocial factors at work according to the policies and guidelines of international bodies and European countries. Results: The process of program policy development was based on a discussion among employer and employee representatives, occupational health professionals, and mental health experts. Scientific evidence shows that mandated components of the program (i.e., feedback of stress survey results and physician's interview) may be ineffective. However, additional components recommended to employers, such as stress management skill provision and work environment improvement, in conjunction with the program may be effective in improving psychosocial stress at work. The Stress Check Program is unique compared with the global trend for psychosocial risk management because it focuses on the assessment of stress among individual workers. Conclusion: The new program may be effective in improving worker mental health by facilitating the psychosocial risk management approach in Japan. Concerns regarding the program include mass leakage of collected information, and possible disadvantages for workers labeled as having high stress.(J Occup Health 2016; 58: 1–6)

Background: Healthcare workers infected with Hepatitis B (HBV) or Hepatitis C virus (HCV) may perform patient care activities if provider-to-patient transmission risks have been assessed in terms of viral load and clinical procedures. The present study investigated potential barriers for the acceptance of colleagues infected with HBV/HCV in healthcare settings after appropriate risk assessment. Methods: We conducted an anonymous, internet-based survey of Japanese nurses. Multivariate logistic analysis was used to assess factors associated with willingness to accept colleagues infected with HBV/HCV after risk assessment. Results: In total, 992 nurses responded to the survey, with 16% indicating that colleagues infected with HBV/HCV should not have patient contact after risk assessment. Willingness to accept HBV/HCV-infected colleagues was negatively associated with attitudes regarding the avoidance of contact with HBV/HCV-infected colleagues (OR: 0.49; 95% CI: 0.28–0.85). Previous professional contact with HBV/HCV patients (OR: 1.73; 95% CI: 1.36–2.12), experience of accidental injection from or personal exposure to HBV/HCV patients (OR: 2.00; 95% CI: 1.42–2.61), knowledge of HBV/HCV (OR: 2.00; 95% CI: 1.52–2.49), and female sex (OR: 1.60; 95% CI: 1.17–2.09) were positively associated with a willingness to accept HBV/HCV-infected colleagues. Conclusions: This study suggests that attitudes regarding the avoidance of contact with HBV/HCV-infected colleagues may be barriers for accepting these colleagues even after risk assessment has been performed. To protect the employment of nurses infected with HBV/HCV, employers should provide comprehensive education for nurses to reduce stigma and improve understanding about the management of staff infected with infectious diseases, such as HBV/HCV.

Objectives: Despite the great impact the migration has had in economic, social and health-related fields, and the repercussions of alcohol consumption on them, few data exist concerning the extent of alcohol consumption in migrant workers. The aims of this study were to identify workers with a hazardous drinking problem by means of a self-reported questionnaire (Alcohol Use Disorders Identification Test-AUDIT) and a biomarker (carbohydrate-deficient transferrin-CDT) and to ascertain associated risk factors. Methods: A cross-sectional survey was conducted using a random sample of 385 migrant workers, undergoing a routine health examination as part of occupational health services. Results: The results showed that 13.8% (n=53) of the workers were screened as positive with the AUDIT (≥ 8) and/or CDT (> 2.6) and identified as hazardous drinkers and that 53.8% (n=207) were teetotallers. Being a man (OR: 2.0), working in the construction industry (OR: 2.8) or agriculture (OR: 2.2), being resident in Spain for more than 7 years (OR: 2.3) and sharing a house with friends were the factors most closely associated with hazardous drinking. Conclusions: Prevention-orientated programs, adjusted to the characteristics of each country and the origin of the migrants themselves, should be instituted to modify the drinking habits of migrant workers considered at risk.

Objectives: After presbycusis, noise exposure is considered the second cause of sensorineural hearing loss. Due to exposure to high-intensity sounds, musicians may be at risk of noise-induced hearing loss (NIHL). Given the importance of good hearing in music career, this study aimed to investigate the frequency of hearing loss and use of protective measures among Iranian musicians. Methods: In this cross-sectional study, 125 musicians, including 21 women (16.8%) and 104 men (83.2%), with at least five years of work experience were recruited. All participants underwent clinical and audiometric examinations. Demographic data, complaints about hearing loss, and information about the use of protective devices were collected through interviews. Results: Audiometric notch in either one or both ears and bilateral hearing loss were present in respectively 42.4% and 19.2% of the participants. The history of tinnitus after performance and ear pain during performance was reported by 64 (51%) and 35 (28%) individuals, respectively. Less than 2% of the participants used hearing protection devices. Conclusions: Long-term exposure to loud sounds puts musicians at risk of hearing loss. However, due to their inadequate knowledge, most musicians never use protective devices to prevent damage to their auditory system.

Objectives: Patients with underlying conditions are at a higher risk of developing sepsis, a systematic response to infection, which has a high mortality rate. After the March 2011 Fukushima Daiichi nuclear power plant accident, there has been an influx of migrant decontamination workers; however, little is known about their health status.Case: A Japanese 55-year-old male decontamination worker, who had several underlying diseases, was transferred to our hospital in cardiopulmonary arrest. He had a history of diabetes mellitus and hypertension and a past history of tuberculosis. Control of underlying conditions was poor, with HbA1c of 13.8% at presentation. He was diagnosed with pneumonia-induced bacteremia and sepsis due to Klebsiella pneumoniae. Although spontaneous circulation returned in emergency room, he died a day after admission.Conclusion: The poor control of underlying diseases seen in this patient could have been influenced by his recent job transfer and engagement in decontamination work and additionally related to his socioeconomic status (SES). This case highlights the need for further research to elucidate the underlying diseases, working conditions, and SES of this population.

Objective: To evaluate the participatory ergonomic method on the development of upper extremity musculoskeletal disorders and disability in office employees. Methods: This study is a randomized controlled intervention study. It comprised 116 office workers using computers. Those in the intervention group were taught office ergonomics and the risk assessment method. Cox proportional hazards model and generalized estimating equations (GEEs) were used. Results: In the 10-month postintervention follow-up, the possibility of developing symptoms was 50.9%. According to multivariate analysis results, the possibility of developing symptoms on the right side of the neck and in the right wrist and hand was significantly less in the intervention group than in the control group (p<0.05). Neck disability/symptom scores over time were significantly lower in the intervention group compared with the control group (p<0.05). Conclusion: The participatory ergonomic intervention decreases the possibility of musculoskeletal complaints and disability/symptom level in office workers.

Introduction Occupational allergy to rodents among laboratory animal workers is common. Most patients generally experience allergic symptoms after the first few years of work. Associated symptoms are usually mild, such as rhinoconjunctivits, urticaria, and asthma. Anaphylaxis, although rare, could be severe and life threatening. Methods We have described in this study two cases of laboratory workers that developed skin and respiratory reactions following laboratory rat and mouse bites, consistent with anaphylaxis. Results Skin testing was found positive for rat epithelium in the patient with anaphylaxis due to rat bite. Elevated levels of specific IgE antibodies against rat and mouse epitheliums were also detected in both the patients. Conclusion These cases illustrate a severe hypersensitivity reaction that could potentially occur in occupational workers that are in close contact with rodents. Reduction of allergen exposure, regular screening, and job modification could be beneficial for affected individuals. Health care workers should be made aware that anaphylaxis could be a serious consequence of laboratory animal bites, particularly in those already sensitized.

Objectives: The aim of this study was to identify the determinants of presenteeism, taking health and individual factors into account. Methods: A quantitative analysis applying structural equation modelling analysis was conducted on the basis of secondary data from the Health and Retirement Survey (2008 wave), which measured presenteeism and its determinants. Results: Stress-related factors at work (β = -0.35, p< 0.001), individual factors (β = -0.27, p< 0.001), and health (β = 0.24, p< 0.001) were significantly related to presenteeism. Individual factors were found to be directly correlated with stress-related factors at work (β =0.22, p< 0.001). Significant indirect effects between stress-related factors at work and presenteeism (Sobel z = -6.61; p< 0.001) and between individual factors and presenteeism (Sobel z = -4.42; p< 0.001), which were mediated by health, were also found. Overall, the final model accounted for 37% (R2 = 0.37) of the variance in presenteeism. Conclusions: Our study indicates some important and practical guidelines for employers to avoid the burdens of stress-related presenteeism among their employees. These findings could help select target factors in the design and implementation of effective presenteeism interventions in the aging working population.

Objectives: The aim of this review was to summarize the lessons learned from the experience in protecting the health of workers engaged in operations following the accident at the Fukushima Daiichi Nuclear Power Plant (NPP). Methods: We reviewed all types of scientific papers examining workers’ health found in Medline and Web of Sciences as well as some official reports published by the Ministry of Health, Labour and Welfare of Japan and other governmental institutes. Results: The papers and reports were classified into those investigating workers at the Fukushima Daiichi and Daini NPPs workers engaged in decontamination operations in designated areas, and other workers. Regarding workers at the NPPs, many efforts were made to establish an emergency-care and occupational health system. Risk management efforts were undertaken for radiation exposure, heat stress, psychological stress, outbreak of infectious diseases, and fitness for work. Only a few reports dealt with decontamination workers and others; however, the health management of these workers was clearly weaker than that for workers at the NPPs. Conclusions: Many lessons can be learned from what occurred. That knowledge can be applied to ongoing decommissioning work and to future disasters. In addition, it is necessary to study the long-term health effects of radiation exposure and to accumulate data about the health of workers engaged in decontamination work and other areas.

Backgrounds: Two-component acrylic resin used in nail art and dentistry can cause allergic contact dermatitis (ACD), but only a few reports from Japan have been published. Cases: A 35-year-old female manicurist (case 1) and 30-year-old female dental hygienist (case 2) were diagnosed with ACD caused by ethyl methacrylate and methyl methacrylate in a liquid monomer of two-component acrylic resin respectively. Case 1 was sensitized from direct skin contact with nail art acrylic products, which could have been avoided, and gave up both being a manicurist and a user. Onset in case 2 occurred when she started to work as an apprentice. She had believed that the cause of her symptoms was use of disposable natural rubber gloves, not a liquid monomer penetrating through her gloves, until she was patch tested positive to (meth)acrylates and liquid monomer. Conclusions: To prevent sensitization, it should be emphasized in occupational training in both specialties that there should be no direct contact with acrylic products and that disposable gloves do not have sufficient protecting properties.(J Occup Health 2014; 56: 229-234)

Objectives: Work ability is a crucial occupational health issue in health care settings where a high physical and psychosocial work capacity is required and a high risk of disabling injuries and illnesses is predictable. This study aims to examine the association between the work ability index (WAI) and individual characterizations, workload, fatigue, and diseases among intensive care units' (ICUs') nurses. Methods: The study sample included 214 nurses selected by a random sampling method from a target population consisting of 321 registered nurses working in eight ICUs. Multiple linear regression analysis was used to test the association between WAI scores and each of the independent variables. Results: Results of multivariate analysis revealed a strong and negative association between WAI scores and diseases (B=-5.82, 95% CI=-7.16, -4.48, P<0.001). Among the studied individual characterizations, body mass index (BMI) was significantly and inversely associated with WAI scores. A significant and negative association was also found between WAI scores and dimensions of MFI-20, such as general fatigue (B=-0.31, 95% CI=-0.53, -0.09, P=0.005) and physical fatigue (B=-0.44, 95% CI=-0.65, -0.23, P<0.001). From dimensions of workload, frustration (B=-0.04, 95% CI=-0.07, -0.02, P<0.001) and temporary demand (B=-0.04, 95% CI=-0.08, -0.0001, P=0.04) showed a negative and significant association with WAI scores, while performance showed a positive and significant association (B=0.04, 95% CI=0.01, 0.07, P=0.005). Conclusions: Based on the study findings, development of health care programs with the aim of setting up a healthy work environment characterized by a well-structured preventive attitude toward controlling diseases, and a well-designed organizational framework toward increasing the level of performance and motivation, reducing the level of fatigue, as well as reducing the workload, is necessary to promote work ability among ICUs' nurses.

Objective: To evaluate the participatory ergonomic method on the development of upper extremity musculoskeletal disorders and disability in office employees. Methods: This study is a randomized controlled intervention study. It comprised 116 office workers using computers. Those in the intervention group were taught office ergonomics and the risk assessment method. Cox proportional hazards model and generalized estimating equations (GEEs) were used. Results: In the 10-month postintervention follow-up, the possibility of developing symptoms was 50.9%. According to multivariate analysis results, the possibility of developing symptoms on the right side of the neck and in the right wrist and hand was significantly less in the intervention group than in the control group (p < 0.05). Neck disability/symptom scores over time were significantly lower in the intervention group compared with the control group (p < 0.05). Conclusion: The participatory ergonomic intervention decreases the possibility of musculoskeletal complaints and disability/symptom level in office workers.
