Occupation Health Status of Workers Exposed to Dust and Industrial Noise in a City along Lancang River Duan Rufei Baoshan Center for Disease Control and Prevention, Yunnan, China Background: With the economical development of west Yunnan along lancang river, More and more industries were introduced Background: Workers exposed to dust and industrial noise can cause silicosis and occupational noise-induced deafness Background: To find occupational contraindication and suspected occupational disease as early as possible is significantly for occupation health surveillance Aims: To understand health status of workers exposed to dust and industrial noise in Baoshan city, supply references to industries in Lancang river areas for occupation health surveillance Method: The total of 1203 workers with silicious dust, cement dust ,tobacco dust and noise occupational hazardous factors were randomly sampled in Baoshan city Occupation health examination was conducted to subjects Method: High kilo-voltage chest radiograph was used as a screening measurement for silicosis Diagnosis of silicosis was undertaken using occupation health surveillance standard (GBZ188-2014) Method: Pure tone audiometry test was used as a screening measurement for hearing loss Diagnosis of hearing loss was undertaken using occupation health surveillance standard (GBZ188-2014) Results: items cases Average height 166.9±6.8 Average weight 63.7±10.7 High kilo-voltage chest radiograph Pneumoconiosis in different industries Wear dust mask percent （ % （ suspected silicosis 0.2 Suspected silicosis at gradeⅠ 0.1 Suspected silicosis at grade Ⅱ 0.25 normal 1197 99.5 Cement industry 0.0 Non-coal industry 100.0 Tobacco processing 0.0 974 81.0 Results: Hearing test cases percent （ % （ Noise occupational contraindication 18 1.5 Average binaural high frequency hearing threshord≧40dB 12 1.0 25dB﹤average binaural high frequency hearing threshord﹤40dB 12 1.0 Normal hearing 1151 95.7 Noise protecting earplug 612 50.9 Results: Variables Working age （ 0=5yaers （ Workshop （ 0=noise85db （ Blood pressure (0=normal （ 1=high blood pressure) Electrocardiogram (0=normal （ 1=abnormal) β SE P value OR 95%CI 0.664 0.263 0.012 1.943 1.160-3.252 1.470 0.432 0.001 4.350 1.867-10.136 0.734 0.431 0.685 0.538 0.284 0.423 2.084 1.539 0.544-7.981 1.215-3.740 Conclusion: 1.Workers in highlighted occupational disease prevention area in Baoshan have a high prevalence of occupational contraindication and hearing loss Conclusion: 2.Noise was the main occupational hazardous factors in this area Conclusion: Enterprises and companies should enhance protection measurement and improve the working environment, especially to protect workers from noise more than 85 dB and working more than years Conclusion: As the core of occupational disease protection, Enterprises should enhance occupational health education and health promotion Especially pay attention to workers at earlier working year
