Symptom prevalence and Primary intervention of work-related musculoskeletal disorders and their related factors among manufacturing workers / 대한산업의학회지

OBJECTIVES: To investigate the symptom prevalence and the primary intervention of work-related musculoskeletal diseases(WMSDs) and their related factors among manufacturing workers. METHOD: A self-administered questionnaire survey was conducted on 2,457 workers, at 22 enterprises in Chungnam province, Korea, from September 1 to December 1, 2003. The contents of the questionnaire included general and work-related characteristics, musculoskeletal symptoms and workers' past one-year experience of primary interventions. RESULTS 1. The overall symptom prevalence of the musculoskeletal diseases was 23.9%. The WMSD symptom prevalences at the neck/shoulder, arm/elbow, hand/wrist and back/leg were 14.8%. 2.7%. 7.3% and 12.0%, respectively. 2. In multivariate analysis, all WMSD symptom prevalences were high in the high workload, high force & high repetitiveness, and 'high job strain' groups. The WMSD symptom prevalence at neck/shoulder was also high in females and the group experiencing low social support from the supervisor. 3. The rates of the primary interventions were as follows : 13.7% for health education, 5.8% for health counselling, 18.8% for preventive exercise, 24.7% for ergonomic intervention, and 9.8% for administrative intervention. 4. In multivariate analysis, the size of the enterprises and the type of occupational health management system(OHMS) were significantly associated with all primary interventions except health counselling(p or =40 years), irregular employment, and the active group of Karasek's job strain model. Those for the preventive exercise were male, older age, longer tenure and regular employment. Those for the ergonomic intervention were longer tenure, job of physical force and/or repetitiveness, high job stain and the group experiencing high social support from the supervisor. The predictive factor for the administrative intervention was male (p<0.05). CONCLUSIONS: To establish an effective strategy for the primary prevention of WMSDs, approaches are needed which consider the individual nature of small and medium sized enterprises. IAlso necessary is to promote the participation of labor and management because the activation of the primary intervention was associated with the type of OHMS and union presence. Moreover the reduction of workload and increased intervention into the high risk group could be effective in the prevention of WMSDs.

Contact dermatitis surveillance system in Taejon city: Prevalence of contact dermatitis among the workers exposed to solvents and nonmentallic chemicals through an immediate health examination system in Taejon city / 대한산업의학회지

OBJECTIVES: We tried to establish a Regional Occupational Surveillance System (ROSS) for estimating the prevalence and monitoring the trend of occupational dermatitis among 718 manufacturing workers exposed to organic solvents and nonmetallic chemicals in small and medium sized businesses of 1,2 industrial complex area of taejon City. METHODS: Through the report from the nurses of Group Occupational Health Management System, we made a case referral and immediate health examination system with occupational medical clinics. We also performed a survey for detecting occupational dermatitis by a self-administered questionnaire. Case must meet 3 criteria; 1) He/She must have one or more significant cutaneous signs and symptoms. 2) The symptom should be changed by the work condition or caused by risk chemicals. 3) Dermatitis should be diagnosed by a doctor. Results Among the 131 workers(17. 7 %) with significant symptoms screened by the questionnaire, 4 workers(0. 6 %) met the case definition criteria. And among the 45 workers (6. 3 9o) referred to the immediate diagnosed system, 14 workers (l. 9 %) were Strongly suspected to have occupational dermatitis. CONCLUSIONS: These prevalence rates were quite underestimated because of deficient recognition of the disease severity among the workers, reversibility of the target diseases, and life-threathening mood due to nationwide economic crisis and the socioeconomic withdrawal of each business. Ultimately, harmonized activities of government, industry, labor unions, volunteer organization and academy relating to occupational health in a community should be encouraged to do creative, consistent efforts for evolution and development of this first trial of ROSS.

Knowledge, Attitude and Practice according to Types of Occupational Health Management / 예방의학회지

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.
