The Relationship of Physical and Psychosocial Risk Factors to Work-related Musculoskeletal Upper Extremity Symptoms amongst Male Automobile Manufacturing Workers: Ki Hyun Lee, Jin Ha Yoon, Sung Kyung Kim, In Jung Cho, Sung Soo Oh, Sung Hoon Kim, Sei Jin Chang, Bong Suk Cha, Sang Baek Koh; Korean Journal of Occupational and Environmental Medicine 2012;24(1):72-85. Published online March 31, 2012; DOI: https://doi.org/10.35371/kjoem.2012.24.1.72

OBJECTIVES
The objective of this study was to determine the relationship of physical and psychosocial risk factors to work-related musculoskeletal upper extremity symptoms amongst automobile manufacturing workers.
METHODS
The cross-sectional study was conducted using male automobile manufacturing workers in order to examine the relationship of physical and psychosocial risk factors to work-related musculoskeletal upper extremity symptoms. A total of 1,793 male workers were asked to complete a self-administered questionnaire. The questionnaire consisted of questions regarding general characteristics, health related behaviors, work-related characteristics, job stress, ergonomic risk factors, and the presence of musculoskeletal symptoms (neck, shoulder, arm, and hand). Work-related musculoskeletal symptoms were evaluated using the National Institute of Occupational Safety and Health (NIOSH) surveillance criteria. In order to measure the physical risk factors, the American National Standard Institute (ANSI) Z-365 Quick checklist was incorporated into the questionnaire. Job stressors were measured using the Korean Occupational Stress Scale (KOSS). A binary logistic regression analysis was performed that examined the relationship of physical and psychosocial risk factors to musculoskeletal symptoms.
RESULTS
The result showed that the physical and psychosocial risk factors were associated with musculoskeletal upper extremity symptoms. The workers with high physical risk factors reported more musculoskeletal symptoms than those having low physical risk factors (OR: 2.37, 95% CI: 1.56~3.62). The workers with high job stress were more likely to have an increased risk of musculoskeletal upper extremity symptom compared to those with normal job stress (OR: 2.65, 95% CI: 2.03~3.47). A significant relationship between the combined effects of physical and psychosocial risk factors on musculoskeletal upper extremity symptoms was also found. The workers exposed to high physical risk factors, high job stress, and long working hours were more likely to report musculoskeletal symptoms than those having low physical risk factors, normal job stress and moderate working hours(OR: 2.37, 95% CI: 1.56~3.62).
CONCLUSIONS
The results suggest that some physical and psychosocial risk factors increase the risk of work-related musculoskeletal upper extremity symptoms amongst automobile manufacturing workers. In order to prevent or reduce musculoskeletal disorders amongst automobile manufacturing workers, it is strongly recommended to manage the physical psychosocial risks occurring in the workplace.

Effect of Genetic Polymorphisms of CYP2E1 and ALDH2 on the Relationship between the Levels of Urinary 8-Hydroxydeoxyguanosine and t,t-Muconic Acid: Yong Dae Kim, Jong Won Kang, Sang Yong Eom, Yan Wei Zhang, Sung Hoon Kim, Eun Young Kim, Chul Ho Lee, Jai Dong Moon, Heon Kim; Korean Journal of Occupational and Environmental Medicine 2007;19(2):164-170. Published online June 30, 2007; DOI: https://doi.org/10.35371/kjoem.2007.19.2.164

Abstract PDF: OBJECTIVES
This study was performed to investigate the effect of genetic polymorphisms on the oxidative genetic damage caused by benzene exposure in workers.
METHODS
We measured urinary t,t-muconic acid levels as a biomarker for benzene exposure and measured the level of urinary 8-OHdG to assess oxidative DNA damage in benzene-exposed healthy male workers. Genetic polymorphisms of ALDH2 and CYP2E1 were determined by TaqMan assay. We estimated Pearson correlation coefficients between urinary t,t-muconic acid and 8-OHdG according to the genetic polymorphisms of CYP2E1 and ALDH2.
RESULTS
There was a significant relationship between urinary t,t-muconic acid and 8-OHdG concentrations in overall subjects (R=0.532, p<0.001). Smokers showed a higher correlation coefficient between the markers than nonsmokers did (R=0.520 vs. 0.010). Individuals with CYP2E1 c1/c1 genotype also showed a higher correlation coefficient between them than those with CYP2E1 c1/c2 or c2/c2 genotypes (R=0.670 vs. -0.145). In multiple linear regression analysis including smoking status, sorbic acid intake, age and genetic polymorphisms of CYP2E1 and ALDH2 as the independent variables, urinary t,t-muconic acid showed a significant association with urinary 8-OHdG.
CONCLUSIONS
There was a significant correlation between urinary 8-OHdG and urinary t,t-muconic acid in benzene-exposed workers. This relationship was affected by genetic polymorphisms of CYP2E1and ALDH2.

Influences of Job Stressors on Psychosocial Well-being, Fatigue and Sleep Sufficiency among Firefighters: Kun Hyung Kim, Jung Won Kim, Sung Hoon Kim; Korean Journal of Occupational and Environmental Medicine 2006;18(3):232-245. Published online September 30, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.3.232

Abstract PDF

OBJECTIVES
To measure the job stressors and stress responses among firefighters.
METHODS
We created a structured, self-reported questionnaire about job stressors using Karasek's Job Content Questionnaire (JCQ), psychosocial stress using Psychosocial Well-being Index, Short Form(PWI-SF) and fatigue using Multidimensional Fatigue Scale (MFS). The questionnaire also included sociodemographic data, job-related factors, and health-related behaviors. We collected questionnaires from 104 male firefighters, 35 male emergency medical service (EMS) rescuers and 28 male administrators in three different municipal fire departments in Busan from September 23 to October 2, 2003. Chi-square test and multiple logistic regression analysis were used to examine the job stressors using SPSS (10.0). The statistical significance level was 0.05.
RESULTS
Both PWI-SF and MFS scores increased in the order of EMS rescuers, firefighters and administrators. Using multiple logistic regression analysis, sleep insufficiency showed statistically significant effects on both PWI-SF (OR=5.19, 95% CI=2.14~12.57) and MFS (OR=2.13, 95% CI=1.02~4.46). Alcohol drinking (OR=0.28, 95% CI=0.10~0.75) had a protective effect on MFS. The odds ratios in job loss and shiftwork were 3.44 (95% CI=1.25~9.42) and 8.69 (95% CI=2.87~26.36) on MFS. Monthly income showed a statistically significant effect on both MFS (OR=5.09, 95% CI=1.34~19.41) and sleep sufficiency (OR=7.27, 95% CI=1.62~32.61). However, there was no statistical significance among the JCQ items on either PWI-SF or MFS.
CONCLUSIONS
Firefighters in this study had potential psychosocial stress and moderate level of fatigue scale. As a causal factor for these outcomes, sleep insufficiency and job loss, lower monthly income and shiftwork were statistically significantly, which confirm the need for countermeasures to ensure optimal sleep time and to raise monthly income. Further follow-up study using more in-depth interview is also required to identify the effects of both alcohol consumption and job loss.

Pulmonary Function and Respiratory Symptoms of Municipal Fire Officers in Busan.: Sung Hoon Kim, Jung Won Kim, Jong Eun Kim, Byung Chul Son, Jeong Ho Kim, Chang Hee Lee, Sang Hwan Jang, Chae Kwan Lee; Korean Journal of Occupational and Environmental Medicine 2006;18(2):103-111. Published online June 30, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.2.103

Abstract PDF

OBJECTIVES
The purpose of this study was to evaluate the relationship between respiratory disorders and fire exposure by investigating and analyzing the lung function and respiratory symptoms of firefighters.
METHODS
The health effects of firefighting on respiratory function were investigated in 699 male fire officers in 4 fire departments in Busan by recording respiratory symptoms and measuring lung function. The data were analysed according to fire exposure and smoking habits.
RESULTS
Mean spirometric data showed significantly decreased levels in the fire-exposed group (FVC, -0.20 L; FVC%, -4.2%; FEV(1) -0.21 L; FEV(1)%, -5.1%; FEF25%, -0.13 L/SEE p<0.05). After stratification by smoking habits, FVC and FEV(1) showed a significant difference between groups. The prevalence of spirometric abnormality was greater for the fire-exposed group than for the non-exposed group. Significantly higher prevalences of nasal stiffness (16.7% vs. 10.9%), sore throat (17.7% vs.14.2%) and chest tightness (6.5% vs. 2.5%) were recorded in firefighters compared to controls (p<0.05). However, after stratification by smoking habits, the 3 symptoms were showed only marginal differences in the smoking group.
CONCLUSIONS
This study demonstrated that fire-exposed firefighters generally suffer a decline of lung function and a higher prevalence of respiratory symptoms. These results suggest that the exposure to routine firefighting activity is associated with adverse health effects to the respiratory system.
