Monitoring results for key occupational diseases in Kaifeng of Henan from 2021 to 2022
Objective To understand the occupational health status of the workers exposed to key occupational hazard factors in the key occupational disease monitoring project in Kaifeng,so as to provide the evidence for clarifying the focus of occupational health work and formulating occupational disease prevention strategies.Methods Through the occupational disease and occupational health information monitoring system of the Chinese Center for Disease Control and Prevention and the platform of Henan Provincial Occupational Health Technology Quality Control Center,the case data reported from occupational health examination institutions in the key occupational disease monitoring projects in Kaifeng from 2021-2022 were collected.The abnormal conditions related to the general health examination indicators such as blood pressure,blood routine,urine routine,alanine aminotransferase and so on,and the special indicators such as noise,benzene and so on were analyzed.Results The numbers of workers exposed to key occupational hazard factors receiving occupational health examination from 2021-2022 were 10 645 and 15174,respectively,the detection rates of suspected occupational diseases were 0.02％(2/10 645)and 0.01％(1/15 174),and the detection rates of occupational contraindications were 1.09％(116/10 645)and 1.23％(187/15 174),respectively.There were significant differences in the detection rates of occupational contraindications among the workers exposed to silicon dust,benzene,noise and welding smoke(x2 were 51.061 and 44.822,respectively,and both P＜0.05).The detection rate of binaural high-frequency average hearing threshold ≥40 dB of noise-exposed workers and the abnormal rate of white blood cell count and neutrophil count of benzene exposed workers in 2022,which were 5.62％(396/7 048),5.33％(68/1 275),and 5.77％(61/1 057),respectively,were higher than those in 2021(x2 were 25.128,10.799,14.931,respectively;all P＜0.05),which were 3.62％(177/4 885),2.69％(31/1 152)and 2.52％(29/1 152),respectively.Three cases of key occupational diseases were newly reported from 2021-2022.Conclusions The most serious occupational hazard factors in Kaifeng City are noise and benzene.The detection rates of suspected occupational disease and occupational contraindication in occupational health examination are low.The management of key enterprises and occupational health examination institutions should be further strengthened,and the monitoring of key occupational diseases and occupational health examination should be promoted.
