Analysis on health status and influencing factors of 1353 mercury workers in Xinjiang

Objective: To investigate the health status of workers exposed to occupational mercury, and to provide the theoretical basis for formulating reasonable health monitoring and targeted protection measures. Methods: In November 2021, 1353 mercury-exposed workers who underwent occupational health examination in a hospital in Xinjiang Uygur Autonomous Region from 2018 to 2021 were collected as research subjects. By analyzing their blood pressure, electrocardiogram, blood routine, liver function and urine β2-microglobulin and urinary mercury in different gender, age, length of service, industry and enterprise scale, and the health status. And the influencing factors of urinary mercury were evaluated. Results: Among 1353 workers exposed to mercury, there were 1002 males (74.1%), the average age was (37.2±9.8) years old, and the length of service was 3.1 (2.0, 8.0) years. The abnormal rates of physical examination, blood pressure, electrocardiogram, blood routine, liver function, urinary β2-microglobulin and urinary mercury were 73.9% (1000/1353), 12.3% (166/1353), 30.2% (408/1353), 59.9% (810/1353), 32.5% (440/1353), 15.2% (205/1353) and 2.2% (30/1353), respectively. The abnormal rates of blood pressure, blood routine, liver function, urinary β2-microglobulin and urinary mercury in male workers were higher than those in female workers (P<0.05). The abnormal rates of workers' blood pressure and physical examination results increased with the increase of age and length of service, while the abnormal rate of electrocardiogram results were opposite (P<0.05). There were statistically significant differences in the abnormal rates of blood pressure, blood routine, urinary β2-microglobulin and physical examination results among workers of different enterprises and different industries (P<0.05). Multivariate logistic regression analysis showed that the workers with age ≥30 years old, microminiature enterprises, abnormal physical examination results and urinary β2-microglobulin were the susceptible population with abnormal urinary mercury (P<0.05) . Conclusion: The occupational health status of mercury workers in Xinjiang Uygur Autonomous Region is not optimistic, and the health monitoring of microminiature enterprises and older workers should be improved to effectively protect the physical and mental health of workers.

РАЗРАБОТКА КОНЦЕПЦИИ ЦИФРОВОГО ДВОЙНИКА РАБОТНИКА РАДИАЦИОННО- И ЯДЕРНО-ОПАСНОГО ПРЕДПРИЯТИЯ И ПРОИЗВОДСТВА

Purpose: Analysis of the possibilities of a predictive model for assessing the risks of pathology of the cardiovascular, cerebrovascular systems and psychophysiological state in workers of radiation and nuclear hazardous enterprises and industries as part of the development of the concept of a digital twin. Material and methods: The study involved employees of one of the leading radiation and nuclear hazardous enterprises, who underwent periodic medical examinations at comprehensive medical health center of the A.I. Burnazyan Federal Medical and Biological Center in September–October 2022. In total 154 patients (115 men and 39 women) were questioned, examined, and analyzed medical records. Diagnostic criteria for risk factors and other pathological conditions and diseases that increase the likelihood of developing chronic non-communicable diseases were evaluated both in accordance with the orders of the Ministry of Health and using the AI-HIPPOCRAT digital prognostic model developed by the Computer Science and Management Federal Research Center. Results: In accordance with the criteria specified in the orders of the Ministry of Health, it was revealed that high or very high risks of developing diseases such as heart attack, stroke, hypertension and depression are observed in 120 people (77.9 %), and according to the analysis in the AI-HIPPOCRAT system, these risks occur in 131 people (85.1 %). Conclusion: As a result of the study, the capabilities of the AI-HIPPOCRATE system were analyzed and the following recommendations were given for its use by workers of radiation and nuclear hazardous enterprises and industries: to integrate the AI-HIPPOCRAT system into the medical information system used at the enterprise; to divide the presented risk factors into three groups: manageable (on which the doctor or patient can influence), conditionally manageable (which can be influenced by the use of drugs) and uncontrollable, which the doctor and the patient cannot manage (for example, gender, age, etc.); to raise the threshold for setting the risk of a particular disease to “high and above”.

Assessment of nutrition and risks of development of the main general pathological syndromes in workers at industrial enterprises

Optimal nutrition is one of the foundations of public health, but before developing and implementing effective programs to improve the nutrition of the able-bodied population at the regional and corporate level, it is important to know the nutritional situation of the target group. The study aims to assess the nutrition and risks of the development of the main general pathological syndromes in workers of industrial enterprises of the Republic of Buryatia. The study was conducted among male workers (n=251) aged 20-64 years, working at an Aircraft factory (group 1, n=71) with an average work experience of 19.72 (16.11; 23.33) years and thermal power plants (group 2, n=72) with an average work experience of 17.00 (13.68; 20.32) years. The comparison group (group 3, n=108) includes workers from the same enterprises without contact with occupational hazards, the average length of service is 19.79 (17.11; 22.48) years. Experts have carried out a nutrition assessment by the questionnaire method, followed by the use of the 24-hour power reproduction method in a computer program. The criteria for dividing into subgroups for assessing actual nutrition were based on the calculation of body mass index and age. We used an automated system for quantifying the risks of major general pathological syndromes (ASQRAS) to assess the health status of employees. Scientists analyzed the results of the study using generally accepted statistical methods. It is shown that the nutrition structure of workers in the main industries of the Republic of Buryatia is suboptimal, characterized by the predominance of the specific weight of total fats, which amounted to 41.03-45.25% of the caloric content of diets mainly due to the high proportion of saturated fatty acids 13.18-14.78%, low proportion of total carbohydrates 38.22-41.09% and critically low dietary fiber content - 2.31-2.50g per 1000 kcal. The obtained significant associations between overweight and various degrees of obesity with the risk of developing nutrition-related diseases, according to ASQRAS results in workers working in harmful conditions at thermal power plants, are probably due to a higher lipid content in their diet (χ2=7.04; p=0.001). The results of this study can be used to substantiate nutrition recommendations at the regional and corporate level. Limitations. The study had certain limitations in the form of survey opportunities, subject to the subjective opinion of respondents. Ethics. The researchers conducted a study in compliance with the Ethical principles set out in the Helsinki Declaration of the World Medical Association of the last revision and the approval of the Local Ethics Committee of the East Siberian Institute of Medical and Environmental Research (conclusion No. 1 of January 14, 2021).

In the innovation economy, organizations seek to integrate digital technologies into all aspects of business, with a digital transformation strategy that encompasses digitization, modernization and change management being key. In today's world, where technologies are rapidly developing, digitalization is one of the key success factors and is the process of implementing and using digital technologies to automate, optimize, and improve business processes. The relevance of the mentioned topic made it necessary to consider the practical possibilities of implementing digitization in the business model, which will allow creating new innovative management models to achieve business success. The article presents the results of research on the importance of using digital transformation to integrate technological tools into international business practice. Recommendations have been developed for implementing business models and providing them with new opportunities in order to generate profit and create additional value in the conditions of globalization and technical progress. It has been proven that a multinational firm, which only unites a set of national enterprises under a global company, has become an anachronism. Instead, large multinational corporations are creating globally integrated organizations that can locate their functions anywhere in the world to take advantage of low costs, the availability of skills or access to local natural resources in the context of digitizing process management. The advantages and challenges of digital transformation are indicated and analyzed, key factors and methods of organization that can ensure successful digitalization of business processes are determined. A study of the possibilities of implementing digitization was conducted using the examples of modern international companies. State-of-the-art digitization services for analysis and optimization of the enterprise's work have been identified. Recommendations for the implementation of digitalization in business processes have been developed, which can be implemented in both international and domestic business. For the implementation of digitalization, it is proposed to define a set of priority tools for the restoration of economic growth, based on the paradigms of the digital economy, taking into account international experience and domestic specifics, which can act as a powerful multiplier of the company's resources.

ДОМІНАНТИ ЦИФРОВОЇ ТРАНСФОРМАЦІЇ ЕКОНОМІЧНОЇ ДІЯЛЬНОСТІ ПРОМИСЛОВИХ ПІДПРИЄМСТВ

The article substantiates that in the conditions of the formation of the fourth and fifth industrial revolutions, the digital transformation of industrial enterprises forms the basis of their further development. The conceptual apparatus "digital economy", "digitalization", "digital transformation" was considered and summarized. The dominants of the digital transformation of the economic activity of industrial enterprises have been identified. The first dominant factor is the adaptation of their economic activity to the conditions of functioning in the digital economy. The specified adaptation should take into account the change in the role of workers of industrial enterprises in the production system, the use of digital technologies in analysis and economic decision-making, the use of intangible factors of production in economic activity, the use of three communication environments of the digital economic space: 1) an internal environment based on the interaction of elements of the production system at the levels: personnel-equipment, equipment-equipment; 2) interaction on the Internet regarding trading goods; 3) a collaborative environment in the development of new or custom products through crowdsourcing. The second dominant factor is the digitization of economic and production processes, which involves the introduction by industrial enterprises of digital technologies related to predicative analytics, production and product life cycle management, digital technologies for designing, developing and improving products, as well as several information technologies that provide an economic component business activities (interaction with suppliers, partners, sales, market analysis, payment systems, etc.). The third dominant factor of the digital transformation of the economic activity of industrial enterprises is substantiated as the processes of digital transformation, which are based on changing the way the production and economic system operates, digitizing business processes and changing the business model by transferring economic interactions into the digital space, forming a value proposition through the use of digital production technologies, introduction into the key areas of activity of digitization of logistics operations, inventory control, etc.

Anthroponymic Personification in Professional Speech and Jargon

The paper studies anthroponymic personification used for naming artefacts in professional and slang speech. The study is based on anthroponymic names recorded in the professional speech of workers (miners, railway and construction workers of the Perm Krai), in the jargon of social communities (youth, criminal, military, and other). The studied units were retrieved from jargon dictionaries, interviews and conversations with workers of Perm mining enterprises, the author’s own observations of the speech of jargon speakers in Perm and miners of the Kizelovsky coal basin. Anthroponymic personifications are considered as facts of subcultures, expressing their value attitudes, as well as a cognitive tool. Personification is regarded as a psychological phenomenon, a verbalization of ideas relating to the inner world of a person. In parallel, this is also a linguistic (semantic) process used for capturing new knowledge in the language, expressing evaluation of a particular object. The purpose of the study is to identify the causes and the means of personification in professional speech and jargons, and to analyze the functions of these names. It was found that the contextual animation of non-living things is a productive way of naming complex professional and highly specialized phenomena, particularly emotionally loaded. Giving human properties to objects of the production and technical sphere stresses their significance in the professional and social community and is used as a way of building professional knowledge. In addition, personification works as a form of a language game based on rethinking the cultural connotations of the word and manipulations with its material form.

Improvement in Body Posture of Sumedang Tofu Small Enterprise Workers Using Workplace Ergonomic Risk Assessment (WERA)

Abstract This study aims to analyse the work body postures, to determine the work risk level before and after the improvement using the Workplace Ergonomic Risk Assessment (WERA) and to improve the workstation by designing ergonomic production tools. An empirical study was carried out at a small industry producing Sumedang Tofu at Rimbo Panjang, Pekanbaru, Indonesia. The workers must bend their body to move 77 kg soybeans with an 11 kg single-lifting capacity. The level of work risk was determined using the Workplace Ergonomic Risk Assessment (WERA) method based on nine categories, i.e., shoulders, wrists, back, legs, neck, strength, vibration, contact pressure, and work duration. The soaking and milling stations scored 35 and 31 using the WERA method. The two scores indicated an average performance level that requires improvement. Anthropometric data were used to develop tools for improving workers' body posture. The new tool used for soaking and milling has footrests, so workers did not have to reach too far above their chests to move the soybeans to the milling. The soaking station and the milling station both achieved a score of 24, which is considered as a low level, indicating that neither station requires improvement. Time reduction after the body posture improvement was 3.33 seconds for the milling station and 2.08 seconds for the soaking station. Keywords: anthropometry, soybean, posture improvement, workplace ergonomic risk assessment Abstrak Penelitian ini bertujuan untuk mengidentifikasi postur kerja untuk mengetahui tingkat risiko kerja sebelum dan sesudah dilakukan perbaikan menggunakan metode Workplace Ergonomic Risk Assessment (WERA) dan memperbaiki workstation dengan merancang alat produksi yang ergonomis. Sebuah studi empiris dilakukan di sebuah usaha kecil tahu Sumedang di Rimbo Panjang, Pekanbaru, Indonesia. Para pekerja perusahaan harus membungkuk untuk memindahkan 77 kg kedelai dengan kapasitas angkat 11 kg. Tingkat risiko kerja ditentukan dengan menggunakan metode Workplace Ergonomic Risk Assessment (WERA) berdasarkan sembilan kategori, yaitu bahu, pergelangan tangan, punggung, kaki, leher, kekuatan, getaran, tekanan kontak, dan durasi kerja. Stasiun perendaman dan stasiun penggilingan memperoleh skor 35 dan 31 dengan menggunakan metode WERA sebelum perbaikan postur tubuh. Kedua skor tersebut menunjukkan tingkat kinerja rata-rata yang memerlukan perbaikan. Data antropometri digunakan untuk mengembangkan alat untuk memperbaiki postur tubuh pekerja. Alat baru yang bisa digunakan untuk merendam dan menggiling ini memiliki pijakan kaki, sehingga pekerja tidak perlu menjangkau terlalu jauh di atas dada untuk memindahkan kedelai ke penggilingan. Stasiun perendaman dan stasiun penggilingan keduanya mencapai skor 24, dengan tingkat yang rendah, menunjukkan bahwa tidak ada stasiun yang memerlukan perbaikan. Pengurangan waktu setelah perbaikan postur tubuh adalah 3,33 detik untuk stasiun penggilingan dan 2,08 detik untuk stasiun perendaman. Keywords: anthropometri, kedelai, perbaikan postur, workplace ergonomic risk assessment

This study is conducted to identify and evaluate the factors affecting the migration behavior of workers in garment enterprises in Vietnam. The subjects selected for the survey are workers who are working at many garment enterprises in some cities and provinces such as Hanoi, Ho Chi Minh, Bac Ninh, Nam Dinh, and Binh Phuoc... By conducting a survey to collect opinions from 312 employees and using SPSS statistical software to test the hypotheses; based on SEM linear structural model with 3 groups of factors affecting the intention to migrate to find job workers and consider the impact of the intention to migrate on the decision to migrate off the workers, the research results show that the factors "Behavior"; "Subjective norm" and "Perceived behavioral control" have a positive impact on the intention to migrate of garment workers with the impact level of +0,523; +0.73; +0.439; and the factor "Migration intention of garment workers" has a positive correlation to "Migration behavior of garment workers" with an impact level of +1.0, meaning the variation of intention to migration will lead to a corresponding change of migration behavior. From the testing, analysis, and evaluation of the factors affecting the migration intention and behavior of workers in Vietnamese garment enterprises, the research team has made some exchanges and discussions to attract more employees to the garment industry, contributing to promoting economic growth and creating sustainable jobs for workers.

Результати дослідження мікробіому пародонтальних кишень у працівників промислових виробництв із шкідливими чинниками

The purpose of the work was to study the microbiome of periodontal pockets in workers of industries with harmful factors, who have generalized periodontitis. Materials and methods. 91 employees of three industrial productions of the Ivano-Frankivsk region took part in the study: employees of chemical production, glass production, and agro-industrial complex. Material for microbiological research was collected from patients during examinations and before the start of treatment using a cotton swab. Inoculation on transport media was carried out directly in the dental office (semi-liquid sugar agar or on glucose-blood agar in Petri dishes). Results and discussion. From the cultured microflora, 18 bacterial cultures were identified in patients of the main group, and 13 – in the control group. Representatives of the group of cocci bacteria: staphylococci, streptococci, neisseria, and anaerobic cocci constituted the main mass of the cultures sown in the examined subjects. Staphylococci, identified as S. epidermidis and S. aureus, which accounted for 18.21% of the total number of cultured strains, dominated among coccal bacteria in patients of the main group. According to the indicated signs, the isolated non-hemolytic and -hemolytic streptococci were identified as S. mutans, S. mitis, S. salivarius, S. sanguis, however, due to the difficulty of identification, in the final accounting they were decided to be considered as non-hemolytic and -hemolytic. Due to the antagonistic effect of streptococci in the oral cavity of healthy individuals, escherichia, in particular E. coli, Proteus and Pseudomonas rods are present for a short time and in small quantities. At the same time, in cultures from patients of the main group, the percentage of S. pyogenes was 12.72%, while it was not cultured in healthy people. A significantly lower frequency of isolation in patients of the main group of conditionally pathogenic “oral” streptococci may indicate inhibition of their growth by pathogenic microflora. In the main and control groups, the percentage of P. anaerobius from the number of isolated strains was 9.23  1.45% and 6.25  3.03%, respectively (р&lt;0.05), that is in patients it was by 1.48 times higher. The percentage of bacteroides identified as B. oralis in the main group was by 1.74 times lower and amounted to 4.49  1.03% and 7.81  3.35% in healthy people (р&lt;0.05). Periodontal pathogens P. intermedia and P. gingivalis were cultured only in patients of the main group. In the main group the fungi Candida spp. were 32.72  6.66%, and in healthy people – 14.06  3.35% of the total number of isolated strains (р&lt;0.05). Conclusion. The analysis of the frequency of seeding of certain types of microorganisms in workers of industrial enterprises with harmful factors proved the generalization of the microflora of the periodontal pockets with the progression of the pathological process in the periodontium. Significant microbial insemination of periodontal pockets of patients compared to healthy ones confirmed the influence of harmful factors of industrial production on the development and course of periodontal diseases in workers, which is realized through the stimulation of the growth of dental plaque and the transformation of the composition of the autoflora in an aggressive direction

WOMEN AT INDUSTRIAL ENTERPRISES OF THE CHUVASH ASSR DURING THE GREAT PATRIOTIC WAR

The article deals with issues related to changes in the structure of workers at industrial enterprises that occurred with the beginning of the Great Patriotic War. On the basis of archival sources and previously published documents, the main directions and features of personnel retraining for the industry of the Chuvash ASSR in the current situation are identified. The influence of historical conditions on the change in the nature of women’s employment is revealed, when women and children who mastered male professions were able to replace the personnel workers of industrial enterprises of the republic at the front. In the most difficult conditions, women participate in the launch of enterprises evacuated to the territory of the republic, adjust newly arriving equipment. The authors analyze how, along with men, women who have only recently completed training and started working, take an active part in various socialist competitions held at industrial enterprises of the republic. The authors come to the conclusion that women, overcoming the difficulties that fell on their shoulders with the beginning of the Great Patriotic War, did everything for four years to provide the front with what was needed for Victory.

Psychological attitude for a healthy lifestyle among workers of an industrial enterprise: the experience of an empirical study

Introduction. The problem of forming a healthy lifestyle among the adult population - working citizens of our country remains relevant and has not yet been resolved. The purpose of the study is to identify psychological attitudes towards a healthy lifestyle among workers of an industrial enterprise. Methods. The empirical study was carried out on the basis of a large Russian industrial enterprise. 300 production workers were interviewed: 150 representatives of working professions (production personnel) and 150 specialists working in offices (office personnel). The diagnostic tools included a specially designed questionnaire to identify the level of formation of a healthy lifestyle, as well as valid and reliable methods: 1) Health Attitude Index (S. D. Deryabo, V. A. Yasvina); 2) Scale of psychological stress psm-25 Lemur-Tessier-Fillion. Statistical methods included percentage and frequency distribution, comparative analysis with the calculation of Student's t-test. Results. An insufficient level of formation of a psychological attitude towards a healthy lifestyle was revealed among both production and office personnel. It has been established that, despite the high value of health, only 10% of workers and 12% of specialists adhere to the principles of a healthy lifestyle. Among the factors influencing health, passive factors independent of the respondent (ecology, heredity, healthcare system) are more often noted. Among corporate practices, preference is given only to those that are associated with full or partial material compensation for actions. Conclusions. Due to the low level of formation of a psychological attitude towards a healthy lifestyle of workers in industrial enterprises, it is advisable to diversify and expand the corporate practices of improving the health of the personnel of organizations with the practices of their psychological support, focused on increasing the level of motivation to comply with the rules of a healthy lifestyle and developing the need for it.

Assessment of the functional state of the cardiovascular system in workers of metallurgical enterprises

In the structure of factors that form the health of the working-age population, the conditions of its production activity occupy an important place. Today, the products of metallurgical industries are used in almost all industries. The study of the state of the cardiovascular systems of workers of a steel wire shop at a large metallurgical enterprise was carried out. An in-depth examination using modern methods of instrumental diagnostics was carried out by 302 employees of the enterprise. Of these — 275 men and 27 women, aged 23 to 59 years. A feature of the working conditions of workers in metallurgical production is the complex effect of the heating microclimate, the severity of the labor process, dust and complex aerosols of metals, which can be risk factors for the development of arterial hypertension at the earliest stages of exposure. A survey of the nature of nutrition and eating behavior showed that 41.2 % of the surveyed showed a high, excessive frequency of consumption of animal fat in persons with arterial hypertension. Examination of workers, aged from 23 to 59 years, revealed arterial hypertension in 19.4 %, signs of arterial hypotension were observed in 7.4 % of the examined workers of the metallurgical plant. In 46.2 % of workers, an increase in blood pressure was revealed, which can be characterized as mild arterial hypertension, in 45.1 % — moderate, and in 8.7 % of the surveyed, an increase in blood pressure can be characterized as a severe degree of arterial hypertension. Metallurgical workers were found to have such risk factors for the development of arterial hypertension as an imbalance in the consumption of plant and animal food, alcohol consumption and psychosocial factors. The state of the cardiovascular system of the workers of the metallurgical plant is characterized by maladaptive somatic changes.

Analysis of influencing factors of high frequency hearing loss in workers exposed to noise based on multilevel model

Objective: To understand the current situation of high-frequency hearing loss of workers exposed to occupational noise in Hubei Province and its multi-level influencing factors. Methods: In June 2021, the basic information, occupational history, physical examination results and other relevant information in the "Occupational Health Examinations Case Cards" for noise workers in Hubei Province in 2020 were extracted from the subsystem of the "China Disease Prevention and Control Information System". Multilevel level of logistic model was used to analyze the related factors of high-frequency hearing loss of noise-exposed workers. Results: In 2020, the incidence rate of occupational high-frequency hearing loss in Hubei Province was 8.25% (6450/78152), and the incidence rate in various regions of the province ranged from 1.13% to 19.87%. At the individual level, male, ≥ 30 years of age, 6-10 years of service, small and micro enterprises, as well as construction, mining, manufacturing, transportation and rental services were the risk factors for high-frequency hearing loss (P<0.05). The risk of high-frequency hearing loss among workers in foreign-funded enterprises was significantly lower than that of workers in state-owned/collective enterprises (P<0.05). At the regional level, the younger the age of the employees, the lower the risk of high-frequency hearing loss (P<0.05). There was no significant correlation between the regional economic level and the risk of high-frequency hearing loss (P>0.05) . Conclusion: The incidence rate of occupational high-frequency hearing loss in Hubei Province is low in 2020, but the incidence rate varies greatly in different regions of the province, mainly due to differences in employment age, while the development of regional economic level has not reduced the risk of occupational high-frequency hearing loss.

Analysis of occupational health examination status of people exposed to vinyl chloride

Objective: To investigate the detection of occupational health for vinyl chloride workers in Tianjin. Methods: In this study, we have collected data from 7 companies with vinyl chloride hazards in 16 districts of Tianjin. Finally, the occupational health surveillance data of 478 vinyl chloride-exposed workers were included in the analysis. Quantitative data was tested for normality. If the data conforms to the normal distribution, using the Mean±SD for statistical description, and t test for statistical analysis. If the data does not conform to the normal distribution, using Median (Q(1), Q(100)) for statistical description, rank sum test for statistical analysis. The qualitative data was described by composition ratio, and the chi-square test was used for statistical analysis. The logistic regression was used to assess the impact on suspected occupational disease and occupational contraindication from personal general conditions, occupational history, company information. Results: The abnormal detection rate of vinyl chloride monomer workers in Binhai New Area was higher than that in other areas (χ(2)=5.20, P=0.023). The abnormal detection rate of vinyl chloride monomer workers in non manufacturing industries was higher than that in manufacturing industries (χ(2)=7.74, P=0.005). The abnormal detection rate of vinyl chloride monomer workers in domestic enterprises was higher than that in foreign invested enterprises (χ(2)=22.38, P<0.01). Compared with the normal group of vinyl chloride monomer workers, the abnormal group of workers was older and had longer working years, The difference was statistically significant (Z=-3.32, -3.54, P=0.001, <0.01). The employer of vinyl chloride monomer workers is in Binhai New Area, the economic type is domestic funded enterprise, the industry is classified as non manufacturing industry, the age is more than 40 years old, and the length of service is more than 20 years old, which is the influencing factor for workers to detect abnormalities (OR=1.875, 95%CI: 1.279~2.749; OR=1.657, 95%CI: 1.071~2.563; OR=3.562, 95%CI: 2.057~6.170; OR=2.166, 95%CI: 1.245~3.768; OR=1.968, 95%CI: 1.345~2.879, all P<0.05) . Conclusion: To protect the health of workers and prevent occupational diseases, the management of vinyl chloride exposure on production process, especially in domestic enterprise, should be improved. Also, better occupational health surveillance should be provided to female workers.
