Risk factors associated with mortality from pneumonia among patients with pneumoconiosis: Bum Seak Jo, Jongin Lee, YounMo Cho, Junsu Byun, Hyoung Ryoul Kim, Jung Wan Koo, Jun Pyo Myong; Ann Occup Environ Med 2016;28:19. Published online April 7, 2016; DOI: https://doi.org/10.1186/s40557-016-0103-6

Background

The aim of this study was to evaluate factors associated with increased risk of mortality from pneumonia among patients with pneumoconiosis.

Methods

Medical records of 103 pneumoconiosis patients hospitalized for pneumonia were investigated. Seven patients who had lung cancer or other malignancy and 13 patients with insufficient medical record were excluded. Two female patients were excluded due to small number to analyze. The subjects were divided into two groups by clinical outcome of pneumonia, the deceased group and the survival group. The two groups were compared in terms of age, smoking history, episode of recent pneumonia, concomitancy of interstitial fibrosis or fungal ball infection, extent of small opacities, grade of large opacities and results of spirometry. Multiple logistic regression was applied to determine the association between these variables and mortality from pneumonia.

Results

The deceased group showed more frequent history of recent pneumonia (p = 0.006), higher prevalence of interstitial fibrosis (p = 0.007) and longer hospitalization period (p = 0.044). The proportion of subjects who had decreased FVC, less than 70 % of predicted value, was higher in the deceased group (p < 0.001). In multiple logistic regression, after adjusting age, smoking history, recent pneumonia, fungal ball, large opacity, profusion and FVC (or FEV₁) less than 70 % of predicted value, history of recent pneumonia, concomitancy of interstitial fibrosis, type of pneumoconiosis and fungal ball presented statistically significant association with mortality from pneumonia.

Conclusions

The concomitancy of fungal ball or interstitial fibrosis, history of recent pneumonia within last 90 days, type of pneumoconiosis, FVC less than 70 % of predicted value, FEV₁ less than 70 % of predicted value presented statistically significant association with mortality from pneumonia. More attention should be given to patients who have such factors when treating pneumonia with pneumoconiosis.

The Assessment of Pulmonary Function in Dental Technicians: Kyoung Han Kim, Jong In Lee, Min Choi, Jun Pyo Myong, Yong Sang Park, Tae Won Jang, Jung Wan Koo; Korean Journal of Occupational and Environmental Medicine 2012;24(4):356-364. Published online December 31, 2012; DOI: https://doi.org/10.35371/kjoem.2012.24.4.356

Abstract PDF: OBJECTIVES
Dental technicians are exposed to various toxic materials in the workplace. The objectives of this study were to assess the pulmonary function of dental technicians and to evaluate the association between work-related factors and pulmonary function of dental technicians.
METHODS
Study subjects were 209 dental technicians in the Korean Dental Technologist Association. A self-report questionnaire including general characteristics, respiratory symptoms, and work-related characteristics was conducted on study subjects, and a pulmonary function test (PFT) was done. Study subjects were classified into two groups(normal and abnormal pulmonary function) based on the pulmonary function test (PFT).
RESULTS
43 subjects (20.6%) among 209 subjects had abnormal pulmonary function. After adjusting for general characteristics such as age, sex, past medical history, familial history, and smoking status, the odds ratio for work duration (per year) was 1.42(95% confidence interval (CI) 1.14~1.83). After adjusting for general and work-related characteristics, the odds ratio for work duration (per year) was 1.48(95% CI 1.18~1.92).
CONCLUSIONS
Dental technicians are exposed to hazardous materials, which might lead to abnormal pulmonary function. A long work duration could increase exposure time, thereby increasing the chance for abnormal pulmonary function. Therefore, pulmonary function tests should be carried out periodically in dental technicians to ensure their pulmonary health.

The Relation between Employees' Lifestyle and Their Health Status in an Electronics Research and Development Company: Jun Pyo Myong, Hyoung Ryoul Kim, Won Seon Choi, Seong Eun Jo, Boram Lee, Jung Wan Koo, Kang Sook Lee, Chung Yill Park; Korean Journal of Occupational and Environmental Medicine 2009;21(1):1-9. Published online March 31, 2009; DOI: https://doi.org/10.35371/kjoem.2009.21.1.1

Abstract PDF

BACKGROUND
An unhealthy lifestyle is the most important cause of lifestyle-induced illness (diabetes, hypertension, liver enzyme abnormality, dyslipidemia etc.). This study was carried out to evaluate that relation between employees' lifestyle and their health status in a Korean electronic research and development company.
METHODS
We conducted a descriptive cross-sectional survey. 3,041 consecutive workers in a Korean R&D company were enrolled in this study. A checkup list for the health examination (from the National Health Insurance Coperation), which contained the information on the lifestyle, and the results of the health examination, which contained information on the body mass index (BMI), systolic blood pressure (SBP), and diastolic blood pressure (DBP), and liver function tests (LFT, AST, ALT, gamma-GTP) and cholesterol profiles (total cholesterol, TG, HDL, LDL) were done for all the subjects. We evaluated the health profile as normal or abnormal. Statistical analysis of the health profiles and the lifestyle of the employees' was performing by using multiple logistic regression analysis.
RESULTS
The prevalence of 'excessive alcohol drinking' was 52.9% (n=1,610), that for 'lack of exercise' was 86.2% (n=2,662), that for 'meat eating' 12.2% (n=370) and that for 'current smoker' was 31.3% (n=952). According to results of health examination, the prevalence of obesity was 27.1% (n=824), hypertension was 7.1% (n=215), diabetes was 1.0% (n=30), abnormal LFT was 15.4% (n=469) and dyslipidemia was 18.7% (n=569). On multiple logistic regression analysis of the health profile and lifestyle, 'meat eating' was related to obesity, hypertension, abnormal LFT (ALT, gamma-GTP), dyslipidemia (LDL). 'Excessive alcohol drinking' was related to obesity, hypertension, abnormal LFT (gamma-GTP). 'Lack of exercise' was related to dyslipidemia (HDL). 'Current smoker' was related to obesity, diabetes, abnormal LFT (ALT, gamma-GTP), and dyslipidemia (TG, HDL) with statistically significance.
CONCLUSIONS
For workers in the R&D company, an unhealthy lifestyle (such as diet, alcohol drinking, lack of exercise and smoking) were related to obesity, hypertension, diabetes, abnormal LFT and dyslipidemia. Therefore health promotion is necessary for the young employees of an Korean R&D company.

Musculo-skeletal Symptoms of Municipal Sanitation Workers and Ergonomic Evaluation on Upperlimb: Jun Pyo Myong, Hyang Ki Lee, Hyoung Ryoul Kim, Hye Sun Jung, Eun Hee Jeong, Woong Nam, Jung Wan Koo; Korean Journal of Occupational and Environmental Medicine 2008;20(2):93-103. Published online June 30, 2008; DOI: https://doi.org/10.35371/kjoem.2008.20.2.93

Abstract PDF

OBJECTIVES
The aim of this study was to estimate musculo-skeletal symtoms of municipal sanitation workers and to evaluate working conditions of municipal sanitation workers to search for the factors related to musculo-skeletal symptoms.
METHODS
We conducted a descriptive cross-sectional survey. The study subjects were comprised of 543 municipal sanitation workers in some divisions of Seoul and the Gyeonggi province. Musculo-skeletal analysis was done by using the modified criteria of NIOSH musuclo-skeletal symptoms, RULA and, REBA. Statistical analysis was done by using the chi-square test, multiple logistic regression analysis.
RESULTS
72.2% of the subjects complained musculo-skeletal symptoms (39.6% on the upperlimbs, 30.0% on the lumbar region, 27.4% on the legs). For the musculo-skeletal symptoms criteria (1~3), street cleaners complained of more musculo-skeletal symptoms than the solid waste collectors, after classifying the jobs of sanitation workers. On logistic regression analysis of the musculo-skeletal "symptoms criteria1" positive groups, age was related to the criteria positive (prevalence odds ratio=1.018, 95% CI: 0.993-1.046). The worktime was significantly related to 'criteria positive 1 and, 2' (prevalence odds ratio=2.165 (95% CI: 1.156-4.131), 2.187 times (95% CI: 1.071-4.651)). The RULA score, the subtotal A score of RULA, the REBA score and , the total A REBA score of the upperlimbs of solid waste collectors were higher than those of the street cleaners.
CONCLUSIONS
In spite of the lower ergonomic evaluation score of the street cleaner, the street cleaners complained of more musculo-skeletal symptoms than did the solid waste collectors due to more frequent repetitive motions, a longer work time (over 10 hours) etc. It is suggested that the sanitation workers need to use the proper methods to avoid musculo-skeletal disease.
