Objectives
Low back pain (LBP) is a common chronic condition among sedentary workers that causes long-term productivity loss. This study aimed to identify the relationships of individual and occupational factors with LBP among Bangladeshi online professionals.
Methods
We conducted a cross-sectional study involving 468 full-time online professionals who usually worked in a sitting position. One-month LBP complaints were assessed using a musculoskeletal subscale of subjective health complaints. The chi-square test was used to measure associations between categorical predictors and LBP, and multivariable logistic regression was conducted to identify the variables significantly associated with LBP.
Results
LBP within the last month was reported by 65.6% of participants. Multivariable logistic regression analysis indicated that age >30 years (adjusted odds ratio [aOR], 0.40; 95% confidence interval [CI], 0.23 to 0.70) and being married (aOR, 0.59; 95% CI, 0.36 to 0.97) had significant negative associations with LBP. Significant positive associations were found for spending >50 hours weekly on average working in a sitting position (aOR, 1.61; 95% CI, 1.05 to 2.49), being overweight and obese (aOR, 1.87; 95% CI, 1.16 to 2.99), sleeping on a soft mattress (aOR, 2.01; 95% CI, 1.06 to 3.80), and ex-smoking status (aOR, 3.33; 95% CI, 1.41 to 7.87).
Conclusions
A high prevalence of LBP was found among full-time online professionals. Long working hours in a sitting position showed a significant association with developing LBP. Smoking history, body mass index, and sleeping arrangements should also be considered while considering solutions for LBP prevalence among online professionals.

Abstract PDF

Objectives
Given that Argentinian public-sector workers are highly exposed to stressful conditions, and that the psychometric properties of the widely used Perceived Stress Scale (PSS) should be evaluated in different settings, this work aimed to compare the psychometric properties of the Latin American Spanish PSS-10 and PSS-4 and to identify the optimal scale for stress assessment.
Methods
A sample of 535 participants was randomly divided into 2 groups to evaluate dimensionality by exploratory and confirmatory factor analyses. The reliability of both scales was also evaluated. Convergent validity was estimated using the Executive Complaints Questionnaire, the average variance extracted, and the composite reliability. Discriminant validity was based on the correlation with the Utrecht Work Engagement Scale and the phi-square correlation between the components.
Results
The factor analyses supported bidimensionality of the PSS-10 (stress and coping), which showed a better fit than the PSS-4. Moreover, the reliability of the PSS-10 was higher, whereas the PSS-4 did not achieve adequate values of internal consistency. The PSS-10 was also correlated significantly with all validation scales, and presented proper internal convergent and divergent validity.
Conclusions
The PSS-10 is a reliable and structurally valid instrument to measure perceived stress and coping in a Latin American Spanish-speaking population with high work demands, and the findings of this study expand our knowledge on the geographical and sociocultural applicability of the PSS.

Abstract PDF: Objectives
The objective of the present study was to validate a shortened transformational leadership (TL) scale (12 items) comprising core TL behaviour and to test the associations of this shortened TL scale with depressive symptoms.
Methods
The study used cross-sectional data from 1632 employees of the overall workforce of a middle-sized German company (51.6% men; mean age, 41.35 years; standard deviation, 9.4 years). TL was assessed with the German version of the Transformational Leadership Inventory and depressive symptoms with the Hospital Anxiety and Depression Scale (HADS). The structural validity of the core TL scale was assessed with confirmatory factor analysis. Associations with depressive symptoms were estimated with structural equation modelling and adjusted logistic regression.
Results
Confirmatory factor analysis and structural equation modelling showed better model fit for the core TL than for the full TL score. Logistic regression revealed 3.61-fold (95% confidence interval [CI], 2.20 to 5.93: women) to 4.46-fold (95% CI, 2.86 to 6.95: men) increased odds of reporting depressive symptoms (HADS score >8) for those in the lowest tertile of reported core TL.
Conclusions
The shortened core TL seems to be a valid instrument for research and training purposes in the context of TL and depressive symptoms in employees. Of particular note, men reporting poor TL were more likely to report depressive symptoms.; Summary

Abstract PDF

OBJECTIVES
The regulatory changes in Korea during the national economic crisis 10 years ago and in the current global recession were analyzed to understand the characteristics of deregulation in labor policies. METHODS: Data for this study were derived from the Korean government's official database for administrative regulations and a government document reporting deregulation. RESULTS: A great deal of business-friendly deregulation took place during both economic crises. Occupational health and safety were the main targets of deregulation in both periods, and the regulation of employment promotion and vocational training was preserved relatively intact. The sector having to do with working conditions and the on-site welfare of workers was also deregulated greatly during the former economic crisis, but not in the current global recession. CONCLUSIONS: Among the three main areas of labor policy, occupational health and safety was most vulnerable to the deregulation in economic crisis of Korea. A probable reason for this is that the impact of deregulation on the health and safety of workers would not be immediately disclosed after the policy change.

Abstract PDF

OBJECTIVES
Due to the economic crisis and globalization, many workers have been suffering from severe occupational stress due to job insecurity and struggles related to downsizing and restructuring. This study aims to assess the stress levels among workers involved in fierce labor disputes and massive layoffs and to evaluate their specific needs and satisfaction with counseling services set up to help workers cope with severely stressful situations? METHODS: The authors provided crisis intervention to workers in traumatic situations to compare the differential level of stress responses and needs among the workers remaining employed in a large auto factory, those laid off by it, and those laid off by other companies in the same region (Pyeongtaek, Gyeonggi Province). We measured stress levels using the worker's stress response inventory (WSRI) and heart rate variability (HRV), and assessed workers' satisfaction with the counseling services. RESULTS: 502 workers participated in the program. Fifty-seven percent of them consulted with occupational problems. The mean WSRI score of the workers remaining employed in the automobile factory was higher than that of the unemployed (employed: 39.8+/-19.9, unemployed: 29.3+/-18.8). Ninety-five percent of workers responded that they were satisfied or very satisfied with the counseling services. CONCLUSIONS: This study suggests the urgent need for the establishment of a national crisis intervention program dedicated to supporting workers in severely stressful situations.

Abstract PDF

OBJECTIVES
This study examined whether serious psychological distress (SPD) is associated with occupational injury among US employees. METHODS: The employed population aged 18-64 years was examined (n=101,855) using data from the National Health Interview Survey (NHIS) 2000-2003. SPD was measured using the Kessler 6-item Psychological Distress Scale (K-6), a screening scale designed to identify persons with serious mental illness. The predicted marginal prevalence of psychological distress and occupational injury with the adjusted odds ratio were estimated using multiple logistic regression analyses. RESULTS: The age-adjusted 3-month prevalence of occupational injury was 0.80+/-0.12% in workers with SPD, which was 37% greater than in workers without SPD (0.58+/-0.03%). The odds of occupational injury in workers with SPD were higher compared to workers without SPD (OR=1.34, 95% CI=0.93-1.92), after controlling for sex, age, race, education, occupation, and activity limitation by at least one medical condition. Male, service and blue collar occupation, and activity limiation by co-morbidity showed significantly higher odds of occupational injury for workers with SPD. CONCLUSIONS: The findings suggest that SPD accounts for an increased likelihood of occupational injury among US employees. A further longitudinal study is needed to differentiate the mechanism or causal pathways linking individual injury risk at the workplace, SPD, and socioeconomic factors.

Abstract PDF: OBJECTIVE
We intended to evaluate the double standard status and to identify factors of determining double standard criteria in multinational corporations of Korea, and specifically those in the occupational health and safety area. METHODS: A postal questionnaire had been sent, between August 2002 and September 2002, to multinational corporations in Korea. A double standard company was defined as those who answered in more than one item as adopting a different standard among the five items regarding double standard identification. By comparing double standard companies with equivalent standard companies, determinants for double standards were then identified using logistic regression analysis. RESULTS: Of multinational corporations, 45.1% had adopted a double standard. Based on the question naire's scale level, the factor of 'characteristic and size of multinational corporation' was found to have the most potent impact on increasing double standard risk. On the variable level, factors of 'number of affiliated companies' and 'existence of an auditing system with the parent company' showed a strong negative impact on double standard risk. CONCLUSION: : Our study suggests that a distinctive approach is needed to manage the occupational safety and health for multinational corporations. This approach should be focused on the specific level of a corporation, not on a country level.; Summary

Abstract PDF: In order to develop the computerized information system of occupational health management at worksite, we surveyed actual states of computer use at worksites. We used a self-administrative questionnaire to the members of Korean Association of Occupational Health Nursing(KAOHN) from July 4 to August 21 in 1997. Among the members of KAOHN, 147 members answered. The worksites where they, were employed were very diverse in aspect of jobs, locations, and size. Occupational health computerized system was used at 30(20.4%) worksites among 147 respondents. When they first introduced the computerized system the most difficult problem was the lack of support of manager. The programs that they have used mainly consist of drug management, health examination management, disease management, but the program of worksite environment management have been rarely used. Most users felt that the computerized system was effective, but there were problems in connection within programs. Many worksites have plans to take or expand the computerized information system within several years. It is necessary to develop the effective and integrated occupational health computerized system.; Summary

Abstract PDF: To perform voluntary occupational health program in worksites, regulational supports are necessary. The regulational supports include assessment of current occupational health program and appropriate incentives. The purpose of this study is to find out the requirements of voluntary occupational health program and conditions to be improved. Study population was industrial health managers of both industries with less than 300 workers and over 300 workers, and the member of labor union who is responsible for safety and health in worksite. Two different questionnaire were used to find out the requirements and conditions to be improved respectively. The results were; 1. The category which prevalence rate of occupational injuries and occupational disease should be lower than national average was most important in health managers employed in industries over 300 workers and followed by reporting system, education, worksite policy, work environment assessment, protective equipment, consequently. But those employed in industries less than 300 workers showed high importance in prevalence rate of occupational injuries and disease, reporting system, worksite policy, work environment assessment, protective equipment, education, consequently. 2. The members of labor union thought that worksite policy was most important and the next is education, reporting system, work environment assessment, protective equipment, prevalence rate of occupational injuries and disease. 3. There were difference in importance of education and worksite policy according to the size of industries. Reporting system, prevalence rate of occupational injuries and disease, and worksite policy had different importance between members of labor union and health managers. 4. In the results of questionnaire for conditions to be improved, the most important condition was top manager's willingness except personal protective equipments, and followed by financial support, legal support. The limitations of this study were the problems of representativeness of study population. but voluntary health program should be performed in worksites which have relatively good occupational health system. So, this selection bias could not disrupt our results.; Summary

Abstract PDF: The first purpose of this study was to compare the mean Knowledge, Attitude & Practice(KAP) scores concerning major occupational Health between two types of occupational health management in small & medium-scale textile factories. Sample number was 1,138 workers. In small & medium factories with 300 workers or less, they have two alternatives for occupational health management; Individual Health Management or Vicarious Health Management. The second purpose was to determine if there was a relationship between duration of Vicarious health management and mean kap scores for 694 workers from the Vicarious Health Management group. We used self-administered questionnaires for measuring KAP. The results of this study were; 1. There was significant difference concerning all socioeconomic & occupational variables(gender, age education level, marital status, Blue/White collar, working duration of present factory, working duration of total factories) except for shift. 2. There was no significant difference of mean scores of Knowledge and attitude between the Individual Health Management Group and the Vicarious Health Management. But, the mean score of Practice was significantly different. 3. According to multiple regression analysis, the mean score of Knowledge significantly increased with age, education level, working duration of all factories increased. The mean score of Attitude significantly increased with age, education level and married. The mean score of Practice significantly increased with age, education level, working duration of all factories, married and men. 4. In conclusion, The type of Health management did not significantly affect the mean KAP scores concerning major occupational Health problems. 5. But, the Duration of Vicarious Health management significantly increased the mean KAP scores.; Summary

Abstract PDF: The purposes of this study are to define the scope of occupational health management and to classify occupational management by review of related journals from 1945 to 1994 in Korea. The steps of this study were as follows: (l)Search of secondary reference; (2) Collection and review of primary reference; (3) Survey; and (4) Analysis and discussion. The results were as follows; 1. Most of the respondents majored in occupational health(71.6%), and were working in university (68.3%), males and over the age 40. Seventy percent of the respondents agreed with the idea that classification of occupational health management is necessary, and 10% disagreed. 2. After integration of the idea of respondents, we reclassified the scope of occupational health management. It was defined 3parts, that is, occupational health system, occupational health service and others (such as assessment, epidemiology, cost-effectiveness analysis and so on). 3. The number of journals on occupational health management was 510. It was slightly increased from 1986 and abruptly increased after 1991. The kinds of journals related to occupational health management were The Korean Journal of occupational Medicine(18.2%), several kinds of Medical College Journal(17.0%), The Korean Journal occupational Health(15.l%), The Korean Journal of preventive Medicine(15.l%) and others(34.6%). As for the contents, the number of journals on occupational health management systems was 33(6.5%) and occupational health services 477(93.5%). Of the journals on occupational health management systems, the number of journals on the occupational health resource system was 15(45.5%), occupational finance system 8(24.2%), occupational health management system 6(l8.2%), occupational organization 3(9.1%) and occupational health delivery system l(3.0%). of the journals on occupational health services, the number of journals on disease management was 269(57.2%), health management 116(24.7%), working environmental management 85(18.1%). As for the subjects, the number of journals on general workers was l85(71.l%), followed by women worker, white color workers and so on. 4. Respondents made occupational health service(such as health management, working environmental management and health education) the first priority of occupational health management. Tied for the second are quality analysis(such as education, training and job contents of occupational health manager) and occupational health systems(such as the recommendation of systems of occupational and general disease and occupational health organization). 5. Thirty seven respondents suggested 48 ideas about the future research of occupational health management. The results were as follows: (l) study of occupational health service 40.5%; (2) Study of organization system 27.1%; (3) Study of occupational health system (e.g. information network) 8.3%; (4) Study of working condition 6.2%; and (5) Study of occupational health service analysis 4.2%.; Summary

Abstract PDF: This study was carried out from 1993 to 1994 in the small industries in Incheon. The objectives of this study was in order to estimate the quitting rate, to identify its relating factors and to propose effective quitting management policy in the small industries. The results were as follows; 1. The quitting rate of 266 study workers was 42.1%(l12 workers). 2. Age, working duration, position, marital status were significant difference between the quitting group and the non-quitting group. 10 the quitting group, mean age was young, working duration was short, general employees and unmarried workers were many compared with the non-quitting group. 3. In the industry characteristics, total assets, total sales, sales per person, establishment duration and occupational health and safety status were significant difference between the quitting group and the non-quitting group. In the quitting group, total assets, total sales and sales per person were little, establishment duration of company was short and occupational health and safety status were poor compared with the non-quitting group. 4. In the quitting group, worker's response to employer's disposal about health and safety was more passive and the relation to employer with employee was significantly poor compared with the non-quitting group. 5. Multiple logistic regression analysis of quitting against family income per person, working duration, relation to employer with employee, occupational health and safety status in industry, worker`s response to employer's disposal about health and safety and sales per person was done. Working duration, occupational health and safety status, worker`s response to empolyer's disposal about health and safety were significant eiplainatory variables for quitting. Above results showed that the quitting rate was high and it was significant difference between the quitting group and non -quitting group according to characteristics of workers and of industries.

Abstract PDF: This study was performed to investigate the knowledge and attitude of workers in small scale industries on health management, and to provide the basic data for more effective service by the group occupational health service system. The knowledge and attitude of 247 workers and 46 health personnel in the industries scattered around Incheon were investigated from December 1992 to February 1993. The results were summarized as follows; 1. There were significant differences between the workers and the health personnel by age, sex, marriage status, job-position and education level. 2. The recognition level of the workers to contract work related disease was significantly higher than that of health personnel, and recognition level of the workers on environmental hazards and on the utility of measuring hazards were lower than that of health personnel. 3. The recognition level on the content of the group occupational health service system was significantly different between workers and health personnel, 72.6% of the responses from the workers answered that they did not know what the group occupational health service system was, but 82.2% of the responses from the health personnel answered that they knew well what it was. And 79.0% of all respondents thought it was necessary for worker's health. 4. seventy three percent of the respondents from the workers indicated that they had never taken health education. However, 93.0% of all respondents answered positively for the need of health education to promote their health. 5. current health service system was judged to be insufficient for the demand of workers for better health. Most of the respondents prefered a formal but flexible health service system and they wanted the periodic health examination to be followed up. It was revealed that despite of poor knowledge, the demand of workers for health service was higher than the current supply. Therefore, this study suggests that educating both health personnel and workers to obtain correct knowledge on the hazards to work environment and health management is needed for effective occupational health service.; Summary

Abstract PDF: The concept of workers' participation in occupational health was introduced to Korea recently in relation to primary health care in occupational health. But there is confusion and debate about workers' participation concept. The purpose of this study was to review the concepts of workers' participation and to conduct evaluation the workers' participation status in occupational health and safety. 394 workers and 54 employers (5.6%) in north area of Kyunggi-Do, were selected and interviewed with a questionnaire by a trained interviewer from August to September 1990. In general, the concept of workers' participation is based on industrial democratization and Declaration of Human Rights which had been powerful ideologies in labor movement. Contrary to workers' participation, community participation is rooted in the Health Rights. So, it is necessary to consider concept of workers' participation to improve participation. The results of survey were as follows: 1. Most of companies (71.75) carried out occupational health education to workers in study area. 2. The Occupational Safety and Health Committee (OSHC) were set up in 24.1% among the study companies, and 72.7% of workers among respondents thought that OSHC was helpful to workers health. 3. The workers signed his name to personal health report in 43.1% and the rate of participation in occupational environment examination was 54.9%. 4. The workers prefer the OSHC (39.3%), owner (35.1%) and union (25.8%) as a occupation health organization, but owners prefer OSHC (54.5%), manager (43.2%) and union (2.3%). 5. Among the factors of the general characteristics, the existence of labor union was a major determinant of workers' attitude and level of workers' participation. As we have seen, most levels of workers' participation are low in occupational health. The variable of existence of labor union among the factors was a major determinant of workers attitude and level of workers' participation. Therefore, in order to promote workers health, it is necessary to ponder long deeply on occupational health care system under the viewpoint of workers' participation.; Summary
