Factors for Approving Cerebrovascular Disorders and Cardiovascular Diseases as Work-related Diseases in Chronically Overworked Workers: Sang Chul Ryu, In Suk Kim, Jong Heon Lee, Jong Uk Won, Tae Won Jang, Young Jun Kwon; Korean Journal of Occupational and Environmental Medicine 2011;23(4):379-386. Published online December 31, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.4.379

OBJECTIVES
This study was conducted to analyze the factors that affected the decision of claims for cerebrovascular disorders and cardiovascular diseases in chronically overworked workers, that submitted their claims after the reformation of approval standards in the Industrial Accident Compensation Insurance Act on 1 July 2008.
METHODS
Of 2909 cases, who claimed between January 1. and December 31. 2009, 1046 cases were selected based on their worker's compensation record and investigated following 6 provincial committees for work-related diseases. The approval rate and odds ratio were analyzed with respect to the general characteristics, past medical history and work-related information using a logistical regression and Student t-test.
RESULTS
Of the 1046 selected cases, the approval rate was 18.5%(194 cases). In the multivariate logistical regression analysis, the factors for approving cerebrovascular disorders and cardiovascular diseases as work-related diseases were found to be the average working time over the last 1 week, occupational category, gender, age, death or survival, the presence of an associated disease, claimed province, and smoking.
CONCLUSION
Factors for approving claims of cerebrovascular disorders and cardiovascular diseases as work-related diseases were the average working time over last 1 week, gender, age, death or survival, claimed disease, presence of associated disease, claimed province, smoking.

The Relationship between Job Stress and hsCRP: Jong Heon Lee, Tae Won Chang, Young Jun Kwon, Yong Kyu Kim, Sang Chul Ryu, In Suk Kim; Korean Journal of Occupational and Environmental Medicine 2011;23(3):261-269. Published online September 30, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.3.261

Abstract PDF

OBJECTIVES
We wanted to investigate the relationship between job stress and high-sensitivity C-reactive proteins (hsCRP) with a view to using them as a predictor of future cardiovascular events.
METHODS
The study subjects were 155 male bank workers. A structured, self-assesment questionnaire was used to analyze the sociodemographic characteristics and job stress of the participants. Seven levels of job stress, as described in the Korean Occupational Stress Scale-Short Form (KOSS-SF), were used to categorized the participants. We included tests for blood pressure, fasting blood sugar, blood lipid level (total cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides), and hsCRP in our analysis. Multiple logistic regression modeling was used to determine an association between job stress and cardiovascular risk factors including hsCRP.
RESULTS
In the multiple logistic regression analyses adjusted for general and job characteristics and cardiovascular risk factors, interpersonal conflict (adjusted OR 1.69, 95% CI=1.11~2.57), job insecurity (adjusted OR 1.94, 95% CI=1.24~3.03) and, occupational climate (adjusted OR 1.89, 95% CI=1.19~3.01) were associated with hsCRP.
CONCLUSION
This study suggests that job stress is associated with hsCRP which is a predictor of future cardiovascular events.

The Effect of a Stretching Exercise on Myofascial Pain Syndrome Patients in Small and Medium Sized Industries: Jung Wook Lim, Young Jun Kwon, Tae Won Jang, Jong Heon Lee, In Seok Kim, Sang Cheol Ryu, Jae Hoon Roh, Jong Uk Won, Bong Suk Cha, Chul Ho Lee; Korean Journal of Occupational and Environmental Medicine 2010;22(4):307-315. Published online December 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.4.307

Abstract PDF

OBJECTIVES
This study was conducted to identify the effect of a stretching exercise on myofascial pain syndrome patients that work in small and medium-sized industry.
METHODS
Questionnaires surveys including general characteristics, work-related characteristics, and musculoskeletal symptoms on neck and shoulder area was administered to 393 subjects who worked in small and medium sized industries. Symptomatic workers were examined to identify whether they had myofascial pain syndrome (MPS). Of the 393 subjects, 108 MPS patients performed 6 weeks stretching exercise program. Intensity of pain was estimated with visual analogue scales (VAS). All patients were interviewed to estimate their compliance to stretching exercise program.
RESULTS
Of the 393 workers, 119 workers were diagnosed with MPS of the neck and shoulder. Post-exercise VAS was significantly reduced compared to pre-exercise VAS (p<0.05). High compliance patients to stretching exercise were more effective to exercise therapy (OR 2.89, 95% CI 1.19~7.04), and overtime workers were less effective to exercise therapy (OR 0.41, 95% CI 0.17~0.95).
CONCLUSION
The Stretching exercise program was identified to be effective in MPS patients in small and medium-sized industries. It is recommended that workers with MPS in small and medium-sized industries practice a well-designed stretching exercise program, and avoid overtime work.
