Improved cardiorespiratory fitness after occupational rehabilitation in merged diagnostic groups: Anne Lovise Nordstoga, Paul Jarle Mork, Marius Steiro Fimland; Ann Occup Environ Med 2018;30:16. Published online February 28, 2018; DOI: https://doi.org/10.1186/s40557-018-0227-y

Background

Various occupational inpatient rehabilitation programs are established in Norway. This study aimed to assess change in cardiorespiratory fitness, pain, anxiety, depression, and quality of life in persons on long-term sick leave due to musculoskeletal-, mental or unspecific disorders after participation in multicomponent inpatient occupational rehabilitation.

Methods

Twenty-five women and five men (mean age 45.2 years, SD 6.7, range 30–57) volunteered to participate in the study. The participants attended either 8 or 17 full days of occupational multicomponent rehabilitation including physical exercise, cognitive behavioral therapy in the form of acceptance and commitment therapy (ACT), and development of a tailored plan for return to work. Cardiorespiratory fitness was assessed by the Åstrand/Ryhming cycle test at the start and end of rehabilitation program, and at one-year follow-up. Changes in somatic and mental health were measured by questionnaires up to 4 months after start of the program.

Results

Linear mixed models showed that the maximal oxygen uptake increased by 1.1 mL°kg-1°min^− 1 during the rehabilitation program and by 3.7 mL°kg-1°min^− 1 at one-year follow-up. There were minor improvements in somatic and mental health, and quality of life.

Conclusions

This study indicates that occupational inpatient multicomponent rehabilitation including physical exercise and ACT may promote a long-term increase in physical exercise that is sufficient to induce a significant increase in cardiorespiratory fitness.

Trial registration

The current study is not registered, but is part of a larger trial registered at clinicaltrials.gov (No.: NCT01926574, registered 21. Aug 2013).

Descriptive study of claims for occupational mental disorders or suicide: Jihoon Lee, Inah Kim, Sooyong Roh; Ann Occup Environ Med 2016;28:61. Published online October 20, 2016; DOI: https://doi.org/10.1186/s40557-016-0147-7

Background

This study aimed to identify the characteristics of claimed mental disorders. Because the workers believed the cause of the mental disorders was work-related stress or a specific event, we could identify the major work-related stressor for claimed cases.

Methods

We included claimed cases of occupational mental disorder or suicide reported during 2010–2014 to the Korea Workers Compensation and Welfare Service (KCOMWEL), established by Industrial Accidents Insurance (IACI) Act. We conducted qualitative analysis using a form specifically developed for this study as well as a quantitative analysis.

Results

Of the 569 claimed cases, 142 cases were recognized as occupational mental disorder or suicide. The approval rate was 24.9 %. Suicide was the most commonly approved mental disorder (23.0 %), followed by major depressive disorder (14.9 %). Regarding profession, 109 workers were managers, and 95 workers were office clerks. The main work-related stressors of the approved cases were acute stressful events (76 cases), long working hours (12 cases), and changes in workload (6 cases). The primary stressful events were work-related legal problems, workplace violence, and employment status-related issues.

Conclusion

Claims due to mental disorders or suicide increased during the 5-year study period, and the approval rate was approximately 33 %, and the main stressor of the claimed cases was an acute stressful event such as physiologic trauma, employment-related issues, fear of legal or financial responsibility, abrupt change in organizational responsibility, or workplace violence.

Objective

The aim of this study was to determine the association between urinary cadmium (U-cd) concentration and diabetes in middle-aged Korean residents of abandoned mines using the first Health Effect Surveillance for Residents in Abandoned Metal mines (HESRAM).

Methods

This study was cross-sectional study conducted on 719 residents between 40–70 years in 38 abandoned metal mines in Korea. Data was collected by HESRAM from 2008 to 2011. The correlation coefficient of U-cd and fasting blood glucose, odds ratio in urinary cadmium tertiles and diabetes prevalence was analyzed according to the sex category.

Results

The correlation coefficient U-cd concentration and fasting blood glucose was 0.182 in male. Logistic regression analysis in male revealed a third tertile odds ratio of U-cd (2 μg/g creatinine < U-cd) while diabetes prevalence was 1.81 (95 % CI 1.05-3.12) with adjusted age, BMI, smoking and alcohol consumption, region, family income. On the other hand, the odds ratio for third tertile of U-cd (3 μg/g creatinine < U-cd) between diabetes prevalence in female was 1.39 (95 % CI 0.52-3.72) in addition to adjusted menopausal status.

Conclusions

Environmental exposure to cadmium in abandoned mine residents was associated with diabetes in male. Closed monitoring and periodic evaluation of the health effects of chronic environmental exposure on abandoned mines residents will be needed.

Mental Disorders and Fitness for Work in Korea: Choong Ryeol Lee, Yang ho Kim, Cheol In Yoo, Ji Ho Lee, Hun Lee; Korean Journal of Occupational and Environmental Medicine 2003;15(3):224-236. Published online September 30, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.3.224

Abstract PDF

OBJECTIVES
This study investigated the actual state of people with mental disorders in Korea, in order to present an alternative proposal for their work fitness and vocational rehabilitation.
METHODS
The authors conducted this study through a review of statistics on the prevalence of mental disorder, labor laws, and the literatures related with work fitness and vocational rehabilitation of people with mental disorders.
RESULTS
According to recent surveys, about 3 million people in Korea are likely to have mental disorders which could lead to discrimination in social life and dishonor in occupational career, either in the present or near future. Therefore, evaluation of work fitness and vocational rehabilitation for persons with mental disorders are important. At present, work fitness for psychiatric patients is evaluated without suitable guidelines regarding the kinds and severity of mental disorders that impede work capacity. Furthermore, mental disorder-specific fitness for work is not under consideration.
CONCLUSION
It is true that most psychiatric patients have some limitation in performing their job. However, judging from the results of some research, proper displacement, apprehension of co-workers, and adjusted workplace could help them complete their tasks properly despite their troublesome psychiatric symptomatology. The government must help all citizens to do their best in their social life, and show a deep interest in the employment of all disabled people including those with psychiatric disorders. Above all we have to change our attitudes and preconceptions against people with mental disorders. Some labor laws, which presently impede employment of people with psychiatric disorders, need to be revised in their favor. Future work capacity evaluation should be done on the basis of ability to function in the workplace rather than symptomatology.
