RESUMO
OBJECTIVE: To study the intervention effects of participatory training on the occupational health in polishing workers. METHODS: By the stratified random sampling method,930 front-line polishing workers were selected from 50 manufacturing enterprises in Guangzhou,467 workers in the intervention group and 463 workers in the control group. The intervention group adopted participatory training and the control group adopted the traditional training. We evaluated the changes of occupational health knowledge,attitude and practice( KAP) in workers of these two groups using the questionnaire table of occupational health KAP for polishing workers. Data of before intervention,immediately after intervention and 3 months after intervention were collected. RESULTS: The workers 'knowledge,attitude and practice scores at the time point of immediately after intervention were higher than those before intervention in the same group( P <0. 05). The workers' knowledge and practice scores of 3 months after intervention in intervention group were higher than those before intervention( P < 0. 05). The knowledge and practice scores of 3 months after intervention in the intervention group were higher than that in the control group( P < 0. 05). The evaluation scores on protection measure and warning signs of workers in the intervention group were lower than those in workers of control group 3 months after the intervention( P < 0. 05). Three months after the intervention,the workers in intervention group believed that the training was more effective than that in the control group in the following 6 aspects: improving the knowledge of occupational health,improving the ability of identifying risk factors, learning to use the personal protective equipment, helping other workmates,having confidence to make suggestions and introducing other workmates to participate in training( P < 0. 05).CONCLUSION: The participatory training is an effective intervention model in improving the workers ' awareness of occupational health KAP.
