ABSTRACT
Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) has played an important role in screening occupational contraindications and preventing occupational diseases since its implementation. However, during the use of occupational health examination, we found that the use of occupational contraindication on cardiovascular disease was not "homogenized" due to the differences in the understanding of various physical examination institutions. Therefore, this paper mainly discussed the connotation and quantitative standards of organic heart disease, arrhythmia, hypertension in the occupational contraindication cardiovascular disease in the specification for "homogenization".

Objective: To investigate the detection of suspected occupational diseases and occupational contraindications for benzene workers in Tianjin. Methods: In June 2020, the occupational health inspection data of 16113 benzene workers in 514 enterprises with benzene hazards in 16 municipal districts in Tianjin from January to December 2019 were included in the analysis. Enterprise information included the employer's region, economic type, industry classification and enterprise scale. Occupational health inspection data for benzene workers during their on-the-job period included routine inspection indicators and benzene special inspection indicators. Multivariate unconditional logistic regression was used to analyze the relationship between personal general information, occupational history, enterprise information and suspected benzene poisoning and occupational contraindications of benzene workers. Results: There were 16073 benzene workers in the normal group and 24 in the suspected benzene poisoning group. The detection rate of suspected benzene poisoning in females was higher than that in males (χ(2)=8.26, P=0.004) . There was no significant difference in the detection rates of suspected benzene poisoning among different dimensions such as age, length of service, occupational health inspection institution location, employer location, industry classification, economic type, and enterprise scale (P>0.05) . There were 16073 benzene workers in the normal group and 16 in the benzene contraindication group. The detection rate of benzene contraindications for workers in suburban areas where occupational health inspection institutions were located was higher than that in urban areas (χ(2)=9.71, P=0.002) , and there was no significant difference in the detection rates of contraindications for benzene in other dimensions (P>0.05) . Multivariate logistic regression analysis showed that female benzene workers were more likely to detect suspected benzene poisoning (OR=3.53, 95%CI: 1.57-7.94, P=0.002) ; benzene workers who received physical examination in suburban occupational health inspection institutions (OR=5.81, 95%CI: 1.94-17.42, P=0.002) , the employer's area was in the suburbs (OR=9.68, 95%CI: 1.23-76.07, P=0.031) , and female workers (OR=3.07, 95%CI: 1.13-8.37, P=0.028) , it was easier to detect occupational contraindications. Conclusion: Female benzene workers with employers located in the suburbs have a higher risk of detecting occupational contraindications, and women are more likely to detect suspected benzene poisoning. The management of benzene operations in the production environment of enterprises in the suburbs of Tianjin and the occupational health monitoring of female workers should be strengthened.

OBJECTIVE: To analyze the diagnosis of occupational disease and the detection status of suspected occupational disease and occupational contraindication in recent years in a petrochemical enterprise. METHODS: The data of new cases of occupational disease reported by a petrochemical enterprise from 2008 to 2019, the cases of suspected occupational disease and occupational contraindication from 2015 to 2019 were collected. The related data was descriptively analyzed. RESULTS: A total of 30 new cases of occupational disease were reported in this petrochemical enterprise from 2008 to 2019. Among them, there were 16 cases of occupational noise deafness, 10 cases of chronic occupational benzene poisoning, 2 cases of occupational leukemia caused by benzene, 1 case of occupational solvent gasoline poisoning and 1 case of occupational pneumoconiosis. Among the 30 cases of occupational diseases, 28 cases(93.3%) were related to benzene and noise exposure, and 19 cases(63.3%) came from the chemical and oil refining divisions. From 2015 to 2019 in this petrochemical enterprise, 24 cases of suspected occupational disease were reported, of which 17(70.8%) suspected cases were diagnosed as occupational disease, and 63 cases of occupational contraindication were reported, including 47(74.6%) cases of occupational contraindication caused by noise. CONCLUSION: Benzene and noise should be taken as the key factors of occupational hazard for prevention and control in the petrochemical enterprises, and control measures should be adopted for special operation links and job posts to control the hidden dangers of benzene and noise that exceeds the standard limits.
ABSTRACT
Objective To investigate the status of occupational health surveillance in Xiacheng District of Hangzhou City from 2014 to 2017, and to provide basis for occupational hygienic supervision Methods Data on occupational health surveillance in Xiacheng District from 2014 to 2017 were collected, and the trend of occupational health surveillance was analyzed.The differences of occupational health surveillance among different hazardous agents, economic types, industries and scales were compared. Results There was no significant difference in rates of pre-job and on-job occupational medical examination from 2014 to 2017, and the rate of off-job occupational medical examination showed an increasing trend.There were statistical difference in on-the-job occupational medical examination rates among empolying units of different economic types, industries and scales.There were statistical differences in the detection rates of occupational contraindication among empolying units of different economic types, hazardous agents.There was no significant difference in the detection rates of suspected occupational diseases among empolying units. Conclusion The occupational health surveillance showed a phenomenon of "emphasizing on-the-job, neglecting pre-job and off-the-job" in Xiacheng District.Supervision department should pay more attention on manufacturing, collective and private economic.It is necessary to focus on the protection of staff contacts with chemical and physical agents. It is suggested that relevant departments should strengthen the propaganda and supervision of occupational health surveillance, according to the nature, characteristics of the employing units and types of their hazardous agents.
ABSTRACT
Objective@#Analyze the detection rates of occupational contraindication and suspected occupational disease from the employee exposure to noise and describe the distribution characteristics.@*Methods@#According to the Technical Specifications for Occupational Health Surveillance (GBZ 188-2014) 、Diagnosis of Occupational Noise-induced Deafness (GBZ 49-2014) and Guideline of Identification of Contraindication to Job Placement (GBZ/T 260-2014) , calculate and analyze the occupational contraindication and suspected occupational disease detection rates of 149 271 workers from January 1st to December 31st in 2015 who were exposed to noise. Analyze the detection rates distribution characteristics between different gender, age, seniority, industry and enterprise scale.@*Results@#The detection rates of occupational contraindication is 2.08%. The suspected occupational disease detection rates of absences workers (2.13%) is higher than during (2.03%) . The occupational contraindication detection rates of< age 20 (2.64%) , 41~50 years old (2.48%) and<1 working years (5.35%) , are higher than others. The detection rates of suspected occupational disease increases with the growth of ages and working years. The occupational contraindication detection rates of scientific research and technology services industry (10.46%) is the highest. The suspected occupational disease detection rates of transportation warehousing and postal services (5.88%) is the highest. The occupational contraindication detection rates of medium-sized enterprise (2.27%) is the highest, meanwhile, the microenterprise’s (1.60%) is the lowest. The suspected occupational disease detection rates of large-scale enterprise (3.21%) is the highest, meanwhile, the microenterprise’s (1.33%) is the lowest.@*Conclusion@#Enterprise should insist on regular occupational health examination, strengthen screening of occupational contraindication in new workers, especially pre-job workers and detect the occupational disease patients early. Focus on non-traditional noise industries above mentioned, improve intensity of noise hazards prevention and control. The detection rates of occupational contraindication and suspected occupational disease can be used as a reference standard for the quality control of occupational examination and report of medical institutions.
ABSTRACT
OBJECTIVE: To examine the hearing status of pre-job workers exposed to noise in metal manufacturing industries,and to analyze the related influencing factors. METHODS: A judgement sampling method was adopted to choose1 597 pre-job workers exposed to noise in metal manufacturing industries as the study subjects. The data of workers' occupational health examination was collected,and the influencing factors of hearing loss were analyzed. RESULTS: Among the 1 597 individuals,631( 39. 5%) cases reported occupational noise exposure history( noise exposure group) with the length of service of 0. 20( 0. 10-0. 30) years; 966( 60. 5%) cases denied occupational noise exposure history( no-noise exposure group). The hearing loss detection rate was 46. 1%( 737 /1 597); among them,the occupational contraindication detection rate was 13. 9%( 222 /1 597),and the detection rate of other kinds of hearing loss was 32. 2%( 515 /1 597).The detection rates in workers with occupational contraindication and the other kinds of hearing loss in noise exposure group were higher than those in the non-noise exposure group( 16. 5% vs 12. 2%,50. 6% vs 43. 3%,P < 0. 05). The male workers had higher incidence than female workers [the odds ratio( OR) were 1. 958 and 2. 331,respectively,P < 0. 01);the workers with age > 25 years had higher incidence than those with age ≤ 25 years( OR were 2. 390 and 2. 245,respectively,P < 0. 01); the noise exposure workers had higher incidence than non-noise exposure ones( OR were 1. 536 and 1. 287,respectively,P < 0. 05). CONCLUSION: Pre-job occupational health examination is helpful for early detection of occupational contraindication in noise exposure workers. Attention should be paid to the male workers,the older workers,and those with occupational noise exposure history when conducting occupational health examination.
