Objective:To investigate the level of occupational health literacy (OHL) of key populations in Gansu Province in 2022, analyze the influencing factors, and provide a scientific basis for the formulation of health education measures for occupational populations.Methods:From April to December 2022, a stratified cluster random sampling method was adopted to select 11472 workers engaged in frontline jobs in 8 key industries across 86 counties and districts in Gansu Province as the research subjects. The "National Occupational Health Literacy Monitoring and Survey Personal Questionnaire" was used to investigate their OHL. The content includes basic demographic information and occupational health literacy level, and the chi-square test analysis was carried out by SPSS 23.0 software, and the influencing factors were analyzed by logistic regression analysis model.Results:In 2022, a total of 11 118 valid questionnaires were completed in Gansu Province, and the OHL level of key populations in Gansu Province was 48.3%. The OHL levels of occupational health legal knowledge, basic knowledge of occupational health protection, basic skills of occupational health protection and healthy working methods were 50.3%, 81.7%, 33.1% and 63.3%, respectively. In the eight key industries, the OHL level of workers from high to low is: ferrous and non-ferrous metal smelting and rolling processing industry (56.6%) , non-metallic mineral products industry (56.5%) , ferrous and non-ferrous metal mining and dressing industry (54.3%) , environmental sanitation industry (50.3%) , medical and health industry (49.9%) , education industry (40.9%) , transportation industry (40.4%) , and express delivery/takeaway delivery industry (23.3%) . The results of logistics regression analysis showed that gender, age, ethnicity, marital status, education level, average monthly income, nature and scale of employers, and length of service were the influencing factors of OHL level of front-line workers in eight industries in Gansu Province (all P<0.05) . Conclusion:In 2022, the OHL level of key populations in Gansu Province was 48.3%, which needs to be further improved. Occupational health publicity should be strengthened for low-income, low-educated, newly recruited, young and micro-enterprise occupational groups.

Objective:The epidemiological characteristics of occupational pneumoconiosis in Gansu Province from 2010 to 2018 were analyzed to provide a theoretical basis for the development of prevention and control strategies for pneumoconiosis in Gansu Province.Methods:In March 2019, the data of newly diagnosed occupational pneumoconiosis in 2010 -2018 and the data of occupational pneumoconiosis as of December 31, 2018 in Gansu Province were collected by the Occupational Disease and Occupational Health Information Monitoring System. The stage, type of disease, time, enterprise information of newly diagnosed pneumoconiosis and the region, type of disease, enterprise information of existed pneumoconiosis were analyzed. Results:From 2010 to 2018, a total of 1269 new cases of occupational pneumoconiosis were reported in Gansu Province, including 818 cases (64.46%) of stage I pneumoconiosis, 284 cases (22.38%) of stage II pneumoconiosis, 167 cases (13.16%) of stage III pneumoconiosis. Silicosis, coal worker's pneumoconiosis and cement pneumoconiosis ranks the top 3, accounting for 55.71% (707/1269) , 37.67% (478/1269) and 3.78% (48/1269) of the total number, respectively. The new cases of stage III pneumoconiosis were mainly distributed in private economy (58.09%, 79/136) and small -sized (59.88%, 97/162) enterprises. As of December 31, 2018, Gansu Province had reported a total of 12211 cases of occupational pneumoconiosis, of which 58.16% (7102/12211) were coal worker's pneumoconiosis and 28.15% (3438/12211) were silicosis. Mainly distributed in Baiyin city (21.63%, 2641/12211) , Lanzhou city (17.79%, 2172/12211) and Wuwei city (13.73%, 1676/12211) . The existed cases of pneumoconiosis are mainly distributed in state -owned economy (76.95%, 9396/12211) and large -sized (54.23%, 6622/12211) enterprises. Conclusion:Silicosis and coal worker's pneumoconiosis are the main type of pneumoconiosis in Gansu Province. And the number of silicosis reported is on the rise, which should be taken seriously. Pneumoconiosis in Gansu Province is mainly distributed in state -owned economy and large -sized enterprises. However, pneumoconiosis patients in private economy and small -sized enterprise is generally serious, so it should be the focus of supervision.

Objective: To analyze the epidemiological characteristics of occupational diseases in Gansu Province, China in 2010-2017, and to provide a scientific basis for the prevention and control of occupational diseases. Methods: The cluster sampling method was adopted to make statistical analysis of 1339 cases of occupational disease reported by "occupational disease and occupational health information monitoring system" in Gansu province from 2010 to 2017, to investigate the diseases, regions and industries of occupational diseases in June 2018. Results: A total of 1339 cases of occupational diseases (39 types, 8 classes) were diagnosed and reposed in 2010-2017. The three most frequent diseases were pneumoconiosis (87.53%, 1172/1339), occupational poisonings (5.83%, 78/1339), and occupational ear, nose, and throat (ENT) diseases (3.14%, 42/1339). The cases of silicosis accounted for 54.61% (640/1172) of all cases of pneumoconiosis, the second was coalworker pneumoconiosis, which accounted for 38.57% (452/1172). In the cases of occupational poisonings, 32.05% (25/78) suffered from carbon monoxide poisoning. Patients with occupational diseases were reported in 14 districts of Gansu, mostly in Lanzhou (27.52%, 347/1261), Jinchang (16.57%, 209/1261), and Baiyin (14.20%, 179/1261). The reported cases are mainly concentrated in mining (71.56%, 468/654) and manufacturing (21.87%, 143/654), the types of state-owned economy (55.63%, 692/1244) and private economy (33.68%, 419/1244), large (43.41%, 540/1244) and small enterprises (35.21%, 438/1244) in 2010-2017 in Gansu. Conclusion The pneumoconiosis caused by silicious and coal dust and the occupational poisonings caused by carbon monoxide seem to be the main occupational hazards in Gansu province. Occupational diseases occur in all districts of Guangzhou and in various industries. The state-owned economy and private sector, large and small enterprises should be the focuses of occupational health supervision.
