목적 : 남성 금속제품 조립 작업자들의 피로에 영향을 미치는 작업관련요인을 파악하고자 한다. 방법 : 작업자의 일반적 특성 및 작업관련 특성, 육체적 부하, 직무 스트레스 등을 조사 항목으로 하여 자동차 부품 조립업 1개소(476명), 자동차 엔진 조립업 1개소(610명), 대형 선박 엔진 조립업 1개소(454명)의 작업자(1,540명)를 대상으로 수거된 설문지 중 부실하게 응답한 38부를 제외한 1,136부(총연구대상의 73.8%)를 분석하였고, 피로도와의 연관성을 다중선형회귀분석으로 살펴보았다. 조사는 자기 기입식 설문지를 사용하였다. 육체적 부하를 측정하기 위해서는 Borg의 scale이 사용되었다. 격무 스트레스를 측정하기 위해서는 Karasek의 Job content questionnaire가 사용되었다. 피로의 측정은 전반적 피로도(sum of fatigue), 일상생활 기능장애(daily dysfunctioning), 상황적 피로(situational fatigue), 피로점수의 총합(sum of fatigue)으로 구성되어 있는 다면적 피로척도를 사용하였다. 피로점수의 분포는 본 연구에 응답한 피로점수의 총합을 사분위수로 나누어서 4등급으로 나누었다. 결과 : 피로점수의 분포는 피로점수의 총합을 사분위수로 나누었을 때, 0≤1등급≤73, 74≤2등급≤82, 83≤3등급≤93, 94≤4등급≤133이었다. 다중선형회귀분석에서 피로점수의 총합과 유의한 관계를 보인 경우는 주간근무, 긴 주당 노동시간, 높은 육체적 부하, 높은 직무요구도, 낮은 직무자율성, 낮은 상사의 지지 등이었고, 전반적 피로도와 유의한 관계를 보인 경우는 주간근무, 높은 육체적 부하, 높은 직무요구도, 낮은 직무자율성, 낮은 상사의 지지 등이었다. 일상생활 기능장애와 유의한 관계를 보인 경우는 주간근무, 긴 주당 노동시간, 높은 육체적 부하, 낮은 직무자율성 등이었다. 상황적 피로와 유의한 관계를 보인 경우는 높은 연령, 주간근무, 긴 주당 노동시간, 낮은 직무자율성 등이었다. 결론 : 피로관련 요인은 긴 주당노동시간, 높은 직무요구도, 높은 육체적 부하, 낮은 직무자율성, 낮은 상사의 지지로 생각된다. Objectives: To find work related factors affecting perceived fatigue among male metal product assemblers. Methods: The study subjects were metal product assemblers from three metal product companies (476 car parts assemblers, 610 car engine assemblers, 454 ship engine assemblers). From the total of 1,540 subjects, 1,136 (73.8%) were included and 38 respondents with insufficient replies were excluded. Associations between fatigue score and other variables (general characteristics, job related factors, workload, job stresses) were investigated in terms of the concept of multidimensional fatigue construct by self administered questionnaire. Using MFS (Multidimensional Fatigue Scale), JCQ (Job Content Questionnaire), and Borg's scale, we estimated the fatigue, job stress, and workload, respectively. Fatigue score was estimated by 'sum of fatigue' in MFS. Associations were tested by linear regression analysis using SAS v.8.0. Results: In this study, the fatigue related factors were older age, longer working hours per week, higher workload, higher job demand, lower decision latitude, and lower supervisor support. Conclusions: Prolonged working hours, higher workload, higher job demand, poor supervisor support and lower decision latitude were fatigue related factors among the male metal product assemblers of this study.

Objective : To elucidate the correlates of self-rated fatigue in Korean employees. Methods : The data for 10,176 (men, 7,984; women, 2,192; mean age, 34.2; SD: 8.8) employees recruited from a nationwide sample were examined. A structured questionnaire was used to measure the participants' fatigue, sociodemographics (sex, age, education, and marital status), job-related characteristics (work duration, grade at work, work hours, shiftwork, employment type, and magnitude of workplace), and health-related habits (smoking, drinking, coffee intake, and exercise). Two types of measurement for fatigue were used to evaluate the magnitude of fatigue: self-rated question and a standardized measurement tool (Multidimensional Fatigue Scale: MFS). Results : According to the self-rated fatigue, 32% of employees reported that they felt fatigue for the past two weeks, and 9.6% of males and 8.7% of females had experienced excessive fatigue (6 months or more). Hierarchical multiple regression analysis showed that fatigue measured by MFS was more common in women, younger, college or more graduated, single, and employees who do not regularly exercise. Fatigue was also associated with long work hours, and the size of the workplace (<1,000 employees). Conclusions : These results suggest that fatigue has been considered as a common complaint, and that it is affected by job-related factors like work hours and the workplace size as well as sociodemographics or health-related behaviors. Further research is needed to clarify the effects of fatigue on adverse health outcomes, work performance, work disability, sick absence and medical utilization, and to examine the relationship of job characteristics (e.g.: work demand, decision latitude) to fatigue.

In order to investigate industrial fatigue of pharmacists, the questionnaire survey for subjective symptoms and its related factors was carried out on 435 pharmacists who were managing pharmacies in Seoul. The questionnaires were composed of three groups of 10 items each, representing dullness and sleepness(Ⅰ), difficulty in concentrations(Ⅱ) and bodily projection of fatigue(Ⅲ). The results were as follows : 1. The complaint rate of fatigue was the highest in 'eye strain' and followed by 'whole body tires', 'apt to forget', 'leg feel heavy', 'feel drowsy' and 'feel like lying' in the descending order. 2. The average weighted score of fatigue complaint was the highest in dullness and sleepness group(Ⅰ) and followed by difficulty in concentrations group(Ⅱ) and bodily projection of fatigue group(Ⅲ) in the descending order, suggestion the heavier mental stress rather than physical burden of the pharmacists work contents. 3. The average weighted scores of fatigue complaints were significantly higher in female and 0-3 off-duty days per month group than those in male and more than 4 off-duty days per month group. 4. The average weighted scores of fatigue complaints were significantly different among the characteristic groups of counselling postures, noise and using chairs. 5. The groups with the high quality of sleeping, regular physical exercise and diet, or satisfied with their job and income had significantly lower average weighted scores of fatigue complaints. 6. The 42.5% of the subjects complained felling heavy chronic fatigue. And the significant differences for average weighted scores were noted among three groups, representing 26.64 in felling heavy chronic fatigue, 18.23 in feeling light chronic fatigue, and 9.50 in feeling no chronic fatigue.

N/A Background : To determine the prevalence of chronic fatigue syndrome and idiopathic chronic fatigue in Korea and to describe demographic, clinical, and psychological differences among those with chronic fatigue syndrome (CFS), those with idiopathic chronic fatigue, and healthy controls. Methods : 1,526 persons aged 18-76 years who visited Korea university hospital health management center for general check-up between December 1998 and August 1999 were participated in the study. The questionnaire made according to the Centers for Disease Control and Prevention criteria was administered to the recruited persons and patients with chronic fatigue syndrome were diagnosed by questionnaire, physical examination and laboratory tests. The Korean version of the Center for Epidemiological Studies-Depression Scale (CES-D) was used to assess depression. Results : Of the 1,526 persons studied, 433 (29.4 %) reported severe fatigue lasting at least 6 months. Of the 202 persons with unexplained chronic fatigue, 31 persons (2.0% of the study population) were classified as CFS cases. The prevalence of CFS was 2.81% in women, 1.49% in men respectively (p<0.05). When CES-D cut-off score of 25 was used, 30.43% of persons with CFS and 5.93% of persons without chronic fatigue had scores suggestive of depression. CFS patients had higher mean scores on CES-D than persons without chronic fatigue (p<0.05). Conclusion : Persons who met the criteria for chronic fatigue syndrome were found in 2.0%. The prevalence of chronic fatigue syndrome in our study were high, compared with previous studies in other countries. CFS patients had higher mean scores on CES-D than persons without chronic fatigue.(Korean J Med 59:529-534, 2000)

Background: Recently, despite the high prevalence of fatigue in patients, there is a lack of research on the quality of life (QoL) in unexplained fatigue patients, indicating that they are not properly diagnosed and treated. The aim of this study was to compare fatigue severity and QoL between patients with explained and unexplained fatigue.Methods: The study consisted of 200 Korean adults who complained of fatigue without underlying disease. Fatigue Severity Scale, Short Form Health Survey-36 version 2 (SF-36v2), and Beck Depression Inventory-II (BDI-II) self-questionnaires were administered. Participants were dichotomized to two groups, namely, patients with unex-plained or explained fatigue, sorted according to laboratory examination results. The chi-square test, t-test, and Wilcoxon rank-sum test were used, and analysis of covariance was calculated after adjusting for age, sex, body mass index, smoking status, and physical component summary (PCS) of SF-36v2 or BDI-II.Results: PCS of SF-36v2 between the two groups showed significant difference. Compared to patients with ex-plained fatigue, those with unexplained fatigue showed lower physical component scores of QoL.Conclusion: QoL of patients with unexplained fatigue could largely diminish than those with explained fatigue. The primary clinician should be aware of poor QoL in patients with unexplained fatigue to identify who is in need of more attention and intervention.

Fatigue in the General Korean Population: Application and Normative Data of the Brief Fatigue Inventory

Yun, Y.H.,Lee, M.K.,Chun, H.N.,Lee, Y.M.,Park, S.M.,Mendoza, T.R.,Wang, X.S.,Cleeland, C.S. Dept. of Anesthesiology, University of Wisconsin-- 2008 Journal of pain and symptom management Vol.36 No.3

The purpose of this study was to provide normative data for the Brief Fatigue Inventory (BFI) in the general Korean population so that the results for the general population could be compared with those for patients. We constructed a questionnaire that included the BFI and items on demographic characteristics and conducted a population-based, cross-sectional survey in 1,000 individuals. We used multivariate logistic analysis to investigate factors associated with ''usual'' and ''worst'' fatigue. The internal consistency was very high (Cronbach's alpha=0.96) and construct validity was confirmed by factor analysis. All patients had a mean+/-SD BFI score of 4.33+/-2.48 for ''worst'' fatigue and of 4.07+/-2.27 for ''usual'' fatigue, and the global BFI score was 3.44+/-2.05. The prevalence of each moderate-to-severe fatigue type was similar in severity of fatigue, with 55.2% in ''usual'' fatigue, and 57.3% in ''worst'' fatigue. Among the types of fatigue, the prevalence of severe fatigue was lowest for ''usual'' fatigue (16.5%). In multivariate analyses, the group aged 40-59 years had greater levels of ''usual'' and ''worst'' fatigue compared with the group aged 20-29 years. Poor general health and the presence of comorbidities were also associated with increased ''usual'' and ''worst'' fatigue. Regular physical activity was associated with reduced levels of ''worst'' fatigue. The normal values of BFI with proper psychometric properties may help us to better understand the correlates of fatigue in the general population and patients. Our findings indicate that comorbidities should be considered when comparing fatigue data from the general population with data from patients.

Backgrounds/Aims: Fatigue is common in chronic hepatitis and end-stage liver disease. However, little is known about fatigue after liver transplantation (LT). We therefore evaluated the prevalence, severity, and related factors of fatigue after LT. Methods: We retrospectively reviewed adult recipients who responded to our survey at outpatient clinics between April and May 2013. Fatigue and its severity were assessed using a questionnaire with the Fatigue Severity Scale (FSS). We defined fatigue as FSS of 4.0 or more and severe fatigue as FSS of 5.1 or more. The related factors including hepatocellular carcinoma and complications were analyzed. Results: A total of 93 patients were included in this study. The mean age was 54.9 (19-76) years and two-thirds were men (67.7%). Living donor LT was 77.4%. Hepatitis B related liver disease was the main underlying disease (77.4%), with hepatocellular carcinoma accompanied in 33.3%. The mean follow-up period was 66.8±43.2 (2-171) months. The mean FFS was 2.83±1.48 (1.0-6.7) overall and 5.10±0.82 (4.0-6.7) in the fatigue group. Of the 93 adult patients, fatigue was presented in 20 patients (21.5%). Among these, 9 patients (45.0%) showed severe fatigue. Even though post-LT complications tended to be greater in the fatigue group (50.0% vs. 30.1% in the non-fatigue group, p=0.098), there were no significant related factors of fatigue after LT, including hepatocellular carcinoma and major complication. Conclusions: Fatigue is present in a considerable portion of recipients after LT, and almost half of them have severe fatigue. Further efforts are needed to decrease fatigue in LT recipients.

Purpose : To identify general characteristics of school personnel with recent fatigue which was the most frequent symptom among subjective symptoms and to explore fatigue-related factors by evaluating physical and perceived health status, life style, and symptoms through data mining techniques. Methods : We collected a data of the 1,147(male 545, female 602) who were elementary, middle, or high school personnel, answered a questionnaire, and received physical examination in Seoul School Health Center from September to November in 2000. And we investigated the differences between fatigue group and non-fatigue group for demographic characteristics, physical health status, perceived health status, symptoms, and laboratory values by frequency, chi-square test, t-test, or simple logistic regression analysis by SAS package 8.1, and then selected significant variables as input variables of a decision tree analysis of CART model by SAS E-miner. Results : In general characteristics, the fatigue consisted of 41.1%(male 35.2%, female 46.4%) among 1,147 school personnel. In classical statistics, factors related with fatigue were female, lower means of systolic and diastolic pressure, young age, personnel in middle school, irregular eating habit, no exercise a week or less than 30minutes exercise a day, perception of unhealthy status, and subjective symptoms including short of breath at exercise. In simple logistic regression to examine the relationship between selected independent variables and fatigue as a dependent variable, the odds ratio of gender (female vs male) was 1.58 times, and young age ( 20s vs 60s) 20.67 times, and middle vs high school personnel 1.86 times. However, we mined combined several characteristics by SAS-E miner. In CART model, if health perception was healthy, and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%. Conclusions : The fatigue consisted of 41.1%(male 35.2%, female 46.4%). In classical statistics, fatigue-related factors among school personnel were young age, female gender, perceived unhealthy status, subjective physical symptoms, poor life-style, and lower blood pressure rather than only physical health status. However, in data mining, if health perception was healthy and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%.

Background/Aims: Many patients with inflammatory boweldisease (IBD) often complain of fatigue. To date, only a fewstudies in Western countries have focused on fatigue relatedto IBD, and fatigue has never been specifically studied inAsian IBD patients. The aim of the present study was to investigatethe fatigue level and fatigue-related factors amongKorean IBD patients. Methods: Patients in remission or withmild to moderate IBD were included. Fatigue was assessedusing the Functional Assessment of Chronic Illness Therapy-Fatigue and the Brief Fatigue Inventory. Correspondinghealthy controls (HCs) also completed both fatigue questionnaires. Results: Sixty patients with Crohn disease and 68patients with ulcerative colitis (UC) were eligible for analysis. The comparison group consisted of 92 HCs. Comparedwith the HCs, both IBD groups were associated with greaterlevels of fatigue (p<0.001). Factors influencing the fatiguescore in UC patients included anemia and a high erythrocytesedimentation rate (ESR). Conclusions: Greater levelsof fatigue were detected in Korean IBD patients comparedwith HCs. Anemia and ESR were determinants of fatigue inUC patients. Physicians need to be aware of fatigue as oneof the important symptoms of IBD to better understand theimpact of fatigue on health-related quality of life.

Objectives: Fatigue is a common symptom experienced by many people who visit Oriental medical clinics or hospital. However, there has been little study about the fatigue in the Oriental medical academic world. For this reason, we attempted to investigate the present status of fatigue of outpatients, and its relation with Health Practice Index(HPI). Methods: The subjects were 63 outpatients who visited the Tonification Clinic in Kyunghee Oriental Medical Center between January 1, 2001 and July 31, 2001. Their chief complaint was fatigue and they did not have any physical or mental problem. They were given a questionnaire which included questions reflecting general characteristics, fatigue degree and health habits. We measured degree of fatigue by Chalder scale et al. Health habits were investigated about 5 articles out of 'Breslow 7 Health habits'. Results: Among the subjects, 48 people(76.2%) were considered as 'fatigue patients' by the Chalder scale. Of this 48 fatigue patients, 27 people(56.3%) had manifested fatigue for more than 6 months. The average of scale II for all the patients was 14.05, which indicates moderate degree of fatigue. They complained fatigue, drowsiness and general weakness, dryness and discomfort of the eyes, headache, shoulder pain and neck stiffness, dizziness, heat in the upper part of the body, and poor concentration. There were no differences in degree of fatigue according to Health habits including exercise or not, smoking or not, the frequency of drinking, hours of sleeping, and body mass index. Conclusions: Many people complain fatigue symptom. Therefore doctors should have more interest in fatigue and care. This study can provide standards of prognosis of fatigue patients. Also prospective studies are needed to find relationship between health habits and fatigue degree.
