[Evaluation of intervention effect in the occupational protection of glass fiber workers by occupational health education].

Abstract

Objective: To understand the mastery of occupational hygienic knowledge and the implementing of occupational health protection measures in the group which were exposed to the procedure of manufacture and use in glass fiber company, and to explore the feasibility of the prevention of the skin injury by occupational health education in glass fiber workers. Methods: We selected 257 on-the-job employees as the research object in a ceramic enterprise in Nanjing from June 2018 to August 2019, with the method of cluster random sampling. According to Solomon's design, the intervention group in which we took measures with health education was divided into RG(1) (O(1)XO(2)) and RG(3) (XO(5)) group, and the control group where we didn't take any intervention was divided into RG(2) (O(3)-O(4)) and RG(4) (-O(6)) group. The intervention effect of health education on the occupational protection of glass fiber workers was evaluated by the results of questionnaire. Results: After training, the average score of occupational health knowledge in the intervention group was 27.34 points higher than that before training, the intervention index was 1.42, 23.62-27.73 points higher than the control glass fiber workers and 33.62-35.52 points higher than the control glass non-glass fiber workers; Compared with the control group, the positive attitude rate of fiber glass workers in the intervention group increased by 13.28%, 13.51%, 11.68% and 11.48%, and the intervention indexes were 1.18, 1.17, 1.14 and 1.15, which was corresponding to using protective cream, wearing gloves, wearing working clothes, washing hands and bathing after work, respectively; Compared with the control group, the implementation rate of occupational protection measures which were represented by wearing gloves、washing hands and bathing for glass fiber workers in the intervention group increased by 29.25% and 7.27% respectively, and the intervention indexes were 1.43 and 1.08 respectively; The skin injury rate of fiberglass workers in the intervention group was reduced by 11.43% comparing to the control group, the intervention index was 1.67. Conclusion: According to the occupational health education of fiberglass workers, it improves the mastery of occupational health knowledge, positive atti-tude rate and the implementation rate of occupational protection measures, meanwhile, it reduces the skin injury rate of the intervention objects to a certain extent.
