Estresse ocupacional entre psicólogos atuantes na atenção primária à saúde no contexto pandêmico / Occupational stress in psychologists working in primary health care in the context of the pandemic / Estrés laboral entre los psicólogos que trabajan en atención primaria de salud en el contexto de la pandemia

Este estudo analisa o estresse ocupacional entre psicólogos que atuavam na Atenção Primária à Saúde durante a pandemia ocasionada pela covid-19, assim como as características sociodemográficas e laborais dos participantes e sua relação com o estresse ocupacional. Participaram da pesquisa 70 psicólogos atuantes em 51 unidades básicas de saúde das regiões Oeste e Extremo Oeste catarinense. Para coleta de dados, um questionário sociodemográfico e a versão reduzida da Job Stress Scale (JSS) foram aplicados. A análise dos dados foi realizada por meio da estatística descritiva e inferencial. Identificou-se que 35,7% dos psicólogos apresentaram alto desgaste no trabalho; 28,6% baixo desgaste; 27,1% se mostraram em trabalho passivo; e 8,6% em trabalho ativo. No modelo de regressão linear, os fatores associados à dimensão Demanda da JSS foram: possuir filho (a) (coeficiente -1,49; IC 95% -2,75 a -0,23) e afastamento do trabalho nos últimos 12 meses (coeficiente 1,88; IC 95% 0,60 a 3,15). Os psicólogos com hipertensão arterial sistêmica autorreferida apresentaram, em média, 3,96 pontos a menos no escore de Apoio social (IC 95% -7,06 a -0,85), quando comparados aos não hipertensos, e entre os psicólogos que trabalhavam no turno da manhã identificou-se aumento de 4,46 pontos, em média, no escore de Apoio social (IC 95% 0,90 a 8,02) em relação aos profissionais do turno manhã e tarde. Evidenciou-se que um número significativo de psicólogos apresentava-se em alto desgaste no trabalho, com potenciais implicações para sua saúde e atuação profissional.(AU)

This study analyzed occupational stress among psychologists who worked in Primary Health Care during the COVID-19 pandemic and participants' sociodemographic and work characteristics and their relationship with occupational stress. In total, 70 psychologists working in 51 basic health units in the West and Far West regions of Santa Catarina participated in this research. A sociodemographic questionnaire and the short version of the Job Stress Scale (JSS) were applied to collect data. Data were analyzed by descriptive and inferential statistics. In total, 35.7% of psychologists showed high stress at work; 28.6%, low burn out; 27.1%, passive work; and 8.6%, active work. The factors in the linear regression model that were associated with the JSS demand dimension referred to having children (coefficient −1.49; 95% CI −2.75 to −0.23) and absence from work in the last 12 months (coefficient 1.88; 95% CI 0.60 to 3.15). Psychologists with self-reported systemic arterial hypertension showed, on average, 3.96 points lower in the Social Support score (95% CI −7.06 to −0.85) than non-hypertensive ones and psychologists who worked in the morning shift, an average increase of 4.46 points in the Social Support score (95% CI 0.90 to 8.02) in relation to professionals working in the morning and afternoon shifts. A significant number of psychologists had high stress at work, with potential implications to their health and professional performance.(AU)

Ergonomía en endoscopia: visualización de una herramienta indispensable en endoscopia / Ergonomics in endoscopy, visualization of an indispensable tool in endoscopy

Endoscopic ergonomics, the study of the endoscopist's interaction with their work environment, aims to adapt tools and actions to their physical and psychological characteristics. Musculoskeletal disorders (MSDs) are highly prevalent among endoscopists (39-89%), mainly due to repetitive movements. This issue is exacerbated by pro- cedures such as EUS, ERCP, and third space endoscopy, which demand more time and instrument use. Despite knowing the risk factors, preventive and modification strategies are scarce in endoscopic centers and the industry. This is concerning, given the impact on health, work disability, and the functioning of endoscopy services. It is crucial to raise awareness and educate on this topic to improve the quality of life of endoscopists and the efficiency of services

La ergonomía endoscópica, que estudia la interacción del endoscopista con su entorno laboral, busca adaptar herramientas y acciones a sus características físicas y psicológicas. Los trastornos musculoesqueléticos (TME) son altamente prevalentes en endoscopistas (39-89%), principalmente debido a movimientos repetitivos. Esta problemática se intensifica con procedimientos como la EUS, ERCP y la endoscopia de tercer espacio, que de- mandan más tiempo y uso de instrumentos. A pesar de conocer los factores de riesgo, las estrategias preventivas y de modificación son escasas en centros endoscópicos y en la industria. Esto es preocupante, dado el impacto en la salud, la incapacidad laboral y el funcionamiento de los servicios de endoscopia. Es crucial visibilizar y educar sobre este tema para mejorar la calidad de vida de los endoscopistas y la eficiencia de los servicios

Valoraciones sobre el proceso de prevención de enfermedades profesionales, a propósito de dos novedades editoriales / Appraisals about the Process for Preventing Professional Diseases. A Propose of two Editorial Updates

En el volumen 37 del último número de la Revista Cubana de Medicina General Integral perteneciente al año 2021, se identifican entre las novedades editoriales dos valiosos trabajos1,2 que motivan una valoración sobre la significación del proceso de prevención de enfermedades profesionales (PPEP), en las condiciones actuales del desarrollo socioeconómico del país. La baja tasa de natalidad y el envejecimiento poblacional, unido a la generación de nuevas formas de gestión económica que incluyen a trabajadores por cuenta propia, usufructuarios de tierras, pequeñas y medianas empresas, en ocasiones carentes de los tradicionales sistemas de seguridad y salud en el trabajo, operados por profesionales especializados, elevan la significación del mandato previsto en el artículo 69 de la Carta Magna, en términos de adopción de medidas adecuadas para la prevención de accidentes y enfermedades profesionales.3 En ese sentido, López y otros2) revelan, mediante revisión científica, las implicaciones del especialista en Medicina General Integral que se desempeña como médico de familia, con el diseño y ejecución de las medidas preventivas referidas en la cita anterior. Estos autores realizan un análisis integrador del Programa del Médico y Enfermera de la Familia y el Programa Nacional de Salud de los Trabajadores, con énfasis en las actividades de salud ocupacional, cuyo resultado constituye, en opinión de la remitente, un referente para reflexionar de manera creadora sobre el mejoramiento del...(AU)

Una pequeña historia de la medicina del trabajo en Venezuela / A short history of occupational medicine in Venezuela

Se presenta una recopilación de hechos relacionados con la salud y seguridad en el trabajo, en forma de aproximación, sin intentar un análisis histórico, siguiendo un hilo transversal del rol de la medicina, en lo que ha significado a través del tiempo la salud física y mental del trabajador. Se discute la contradicción entre la salud y el trabajo, intentando dar una explicación de cómo los diferentes sistemas económicos han intentado mediar en esta contradicción. El artículo hace hincapié en las circunstancias, que en el caso venezolano, condujeron al desarrollo de hecho y de derecho de la atención de la salud de quien trabaja, primero de nuestros ancestros, los indios americanos, luego de los esclavos negros y con el pasar del tiempo, de los trabajadores de las minas en el siglo XIX y delos trabajadores petroleros en el siglo XX, siglo que a partir de 1950, con la graduación en Inglaterra del primer médico ocupacional venezolano, el Dr. Emigdio Cañizales Guédez, vio crecer exponencialmente los profesionales que se sumaron a este campo del ejercicio profesional, que incluyó servicios en las empresas, gremios, y finalmente, los postgrados. Se trae a la memoria a personas de todo el país, que, desde su lugar de acción, dieron su aporte para que la Medicina del Trabajo o Medicina Ocupacional ocupe hoy un lugar estratégico en lo que significa la empresa nacional, sea pública o privada(AU)

A compilation of facts related to health and safety at work is presented, in the form of an approximation, without attempting a historical analysis, following a transversal thread of the role of medicine in what physical and mental health has meant over time. Who works the contradiction between health and work is discussed, trying to explain how different economic systems have tried to mediate this contradiction. The article emphasizes the circumstances that in the Venezuelan case led to the de facto and legal development of health care, first of our ancestors, the American Indians, then of the black slaves and over time of the workers of the mines in the 19th century and of the oil workers in the 20th century, a century that from1950, with the graduation in England of the first Venezuelan occupational doctor, Dr. Emigdio Cañizales Guédez, will see the professionals who joined grow exponentially. To this field of professional practice, which will include services in companies, trade unions and finally postgraduate courses. The article brings to mind people from all over the country, who from their place of action, gave their contribution so that Occupational Medicine or Occupational Medicine now occupies a strategic place in what the national company means, whether public or private(AU)

Riesgo de cáncer en bomberos / Cancer risk in firefighters

INTRODUCCIÓN: El Centro Internacional de Investigaciones sobre el Cáncer incluyó la exposición ocupacional y ambiental de bomberos, en su listado de carcinógenos para humanos. MATERIAL Y MÉTODOS: Se realizó un scoping review de la literatura disponible sobre el riesgo de cáncer en bomberos, inicialmente una búsqueda primaria de artículos publicados en los últimos 10 años en PubMed, usando los términos MeSH "Neoplasms" AND "Firefighters", encontrándose un total de 38 textos. Adicionalmente, se realizó una búsqueda secundaria en la misma base de datos y período de tiempo, utilizando los términos "Ocupational Exposure" AND "Risk" AND "Firefighters" AND "Cancer" encontrándose 77 artículos. De este listado se seleccionaron 3 artículos de la búsqueda primaria y 3 de la búsqueda secundaria que fueron incluidos en la revisión. RESULTADOS: Se ha documentado que los bomberos están potencialmente expuestos, en todos los tipos de emergencias con fuego, a una variedad de sustancias tóxicas y cancerígenas. En diversos metaanálisis y revisiones sistemáticas se encontraron asociaciones entre la extinción de incendios y algunos tipos de cáncer. Conclusiones: Identificar asociaciones entre las exposiciones ocupacionales de los bomberos y el riesgo de cáncer es una tarea desafiante principalmente debido al origen multifactorial del cáncer. La mejor forma de disminuir la exposición es implementando medidas de prevención.

INTRODUCTION: the International Agency for Research on Cancer included the occupational and environmental exposure of firefighters, in the list of carcinogens for humans. MATERIAL AND METHODS: A scoping review of the available literature on the risk of cancer in firefighters was carried out. Results: It has been documented that firefighters are potentially exposed, in all types of fire emergencies, to a variety of toxic and carcinogenic substances. In several meta-analyses and systematic reviews, associations were found between firefighting and some types of cancer. CONCLUSIONS: Identifying associations between firefighters' occupational exposures and cancer risk is a challenging task mainly due to the multifactorial origin of cancer. The best way to reduce exposure is to implement preventative measures.

Abstract: This study, presented in the form of an article, is part of the Care Process in Health and Nursing research line of the Postgraduate Program in Nursing, and the Multiprofessional Research Group in Adult Health at the Universidade Federal do Paraná. Introduction: nasal and paranasal sinus cancer corresponds to less than 1% of other types of cancer, has etiological factors resulting from the environment, occupational activities and lifestyle, and a latency period varying up to 20 years for the onset of neoplastic symptoms. Objectives: to characterize the sociodemographic, clinical and occupational profile of Brazilians with sinonasal cancer; translate, culturally adapt and validate the Questionario Sulla Storia di Lavoro e Sulle Abitudini di Vita used by the Registro Tumori Seni Nasali e Paranasali from Lombardy, Italy, for the Brazilian cultural context; to examine the sociodemographic, clinical and occupational profile of patients with sinonasal cancer, and relate the occupation to exposure to leather dust,wood dust, chromium and nickel. Article 1: is an observational, descriptive, retrospective study using secondary data from the Hospital Cancer Registry Integrator from 2007 to 2019 with ICDs: C30.0 and C31.0 to C31.9. Analysis of 1,803 records was performed, highlighting that 1,161 (64%) were male, predominant age group of 50-59 years (26%; n=298), white race/color (46%; n=535) , single (55%; n=640), incomplete primary education (40%; n=461), with incidence of neoplasia in the maxillary sinus (52%; n=943), and clinical staging grade IV (32%; n=575). The occupations registered in Brazilians with sinonasal cancer were in Group 6 (64.7%; n=701) - agricultural, forestry and fishing workers, and in Group 8 (26.7%; n=289) - workers in the production of industrial goods and services, mainly in the states of Bahia (11%; n=206) and Minas Gerais (18%; n=327). Article 2: describes a methodological study with the steps of translation, synthesis, back-translation, back-translation report, review, pilot test and final translation proposed by the European Organization for Research and Treatment of Cancer. The instrument was divided into 11 domains according to characteristics of the questions in the original instrument. The pre-test was carried out between July and September 2021 in a reference hospital in oncology in the state of Paraná, Brazil, with 15 participants that were patients with nasal and paranasal sinus cancer, and five family members. The instrument obtained an index of 94% agreement among judges, who made suggestions for inclusion, semantic maintenance and replacement in 11 domains. In the pre-test, although participants confirmed their 100% (n=15) understanding of questions and domains, all had difficulty interpreting the word "popper", and 53% (n=8) made suggestions for improvements in the questionnaire. One participant requested the inclusion of hookah in smoking habits. Article 3: consists of a case series report from an oncology hospital in the state of Paraná, southern Brazil, from 2005 to 2021. Patients of both sexes aged over 18 years, with ICD C30 and group C31, under healthcare in the last 12 months at the hospital, or family members (in the case of patient's death) aged 18 years or older were included. Participants were interviewed using the Work History and Lifestyle Questionnaire. The data obtained were analyzed by simple and absolute frequency. Results: Article 3 had 52 participants that were male (56%; n= 29), married (31%; n= 16), with complete primary education (23%; n= 12) and no history of smoking (27 %; n=14), and the prevalent location was C30.0 in men (33%; n=17) with squamous cell carcinoma (40.3%; n=21). Carcinogenic exposure to wood dust (29.8%; n=17), chromium and nickel (17.5%; n=10), and leather and leather products (14%; n=8). Conclusion: the frequency of nasal and paranasal sinus cancer was higher in males with primary education, in agricultural workers and in the manufacturing industry who were exposed to the carcinogenic agent; the study may motivate reflections on the involvement of nasal and paranasal sinus cancer in the Brazilian context, mainly of occupational origin, according to monographs of the International Agency for Research on Cancer, which emphasizes the importance of using a research instrument with complex and essential information of occupational history and lifestyle habits directed to nasal and paranasal sinus cancer.

Ambiente de trabalho seguro e sustentável: como a ergonomia de conscientização e participativa se aplica aos servidores públicos? / Safe, sustainable work environment: how awareness and participatory ergonomics can be applied to public servers? / Un entorno de trabajo seguro y sostenible: ¿cómo aplicar la sensibilización y la ergonomía participativa a los servidores públicos?

Introdução: As práticas ergonômicas de conscientização e de participação assumem importante papel na prevenção das doenças ocupacionais. Entretanto, os métodos utilizados pelos programas de prevenção das instituições e empresas visam a correção dos riscos ergonômicos, não observando o fator humano detentor da execução da tarefa. Objetivo: Analisar a utilização das Ergonomia de Conscientização e Participa- ção como programa de educação visando a prevenção primária e a conscientização dos riscos ergonômicos das lesões por esforço repetitivo (LER) e distúrbios osteomusculares relacionadas ao trabalho (DORT). Metodologia: Revisão crítica de literatura, sintetizando o embasamento teórico pertinente ao tema, com documentação técnica, normas, decretos, portarias e dados estatísticos atualizados de afastamento; formando, assim, à análise documental. Resultados e Discussão: Os dados estatísticos mostram a importância de uma mudança nos hábitos, nos programas e nas intervenções ergonômicas no ambiente laboral do trabalhador, visando minimizar os impactos socioeconômicos dos altos índices de afastamento para organizações, empresas privadas e, principalmente, serviços públicos de ensino superior devido a maior precariedade dos ambientes de trabalho. Práticas ergo- nômicas de conscientização e participação dos trabalhadores podem proporcionar uma melhora nos desconfortos do ambiente laboral. Ressalta-se a escassez de pesquisas que priorizem a relação custo-benefício e a eficácia a longo prazo na área de Ergonomia. Conclusões: Novas análises devem ser observadas para promover melhora da qualidade de vida do trabalhador, diminuição das perdas econômicas, contribuindo para um trabalho seguro, decente e sustentável como preconiza principalmente o Objetivo 8 da Agenda 2030 da Organização das Nações Unidas.

Introduction: Ergonomic awareness and participation practices play an im- portant role in the prevention of occupational diseases. However, the methods used by institutions and companies' prevention programs aim to correct ergonomic risks and do not observe the human factor responsible for carrying out the task. Purpose: To analyze the use of Participation and Awareness Ergonomics as an education program aimed at raising awareness of ergonomic risks for the prevention of repetitive strain injuries (RSI) and work-related musculoskeletal disorders (WRMD). Methodology: Critical literature review, summarizing the theoretical basis relevant to the topic, with technical documen- tation, norms, decrees, ordinances, and updated statistical data on leave; thus forming the documental analysis. Results and discussion: Statistical data show the importance of changing habits, programs, and ergonomic interventions in the work environment of the worker, in order to minimize the socioeconomic impacts of the high removal rates of organizations, private companies, and, mainly, public higher education due to more pre- carious work environments. Ergonomic practices of awareness and participation of work- ers can improve the work environment's discomfort. The lack of research that prioritizes the cost-benefit ratio and long-term effectiveness in Ergonomics is highlighted. Conclu- sions: New studies must promote a significant improvement of the quality of life of work- ers, reduction of economic losses and, thus contribute to a safe environment, decent and sustainable, as advocated by Objective 8 of the United Nations 2030 Agenda.

Introducción: Las prácticas de sensibilización y participación ergonómicas desempeñan un papel importante en la prevención de las enfermedades profesionales. Sin embargo, los métodos utilizados por los programas de prevención de instituciones y em- presas tienen como objetivo corregir los riesgos ergonómicos y no observan el factor hu- mano responsable de la realización de la tarea. Propósito: Analizar el uso de la Ergonomía de Participación y Concienciación como programa educativo dirigido a la concienciación de los riesgos ergonómicos para la prevención de las lesiones por esfuerzos repetitivos (LER) y los trastornos musculoesqueléticos de origen laboral (TME). Metodología: Re- visión lit-eratura crítica, resumiendo la base teórica relevante al tema, con documentación técnica, normas, decretos, ordenanzas, y datos estadísticos actualizados sobre bajas la- borales; conformando así el análisis documental. Resultados y discusión: Los datos es- tadísticos demuestran la importancia del cambio de hábitos, programas e intervenciones ergonómicas en el ambiente de trabajo del trabajador, para minimizar los impactos soci- oeconómicos de los altos índices de desvinculación de organizaciones, empresas privadas y, principalmente, de la enseñanza superior pública, debido a la mayor precariedad de los ambientes de trabajo. Práticas ergonómicas de conscientização e par-ticipação dos tra- balhadores podem melhorar a incomodidade do ambiente de trabalho. Se destaca la falta de re-investigación que priorice la relación costo-beneficio y la eficacia a largo plazo en Ergonomía. Conclusiones: Nuevos estudios deben promover una mejora significativa de la calidad de vida de los trabajadores, la reducción de las pérdidas económicas y, así contribuir a un entorno seguro, digno y sostenible, como propugna el Objetivo 8 de la Agenda 2030 de las Na-ciones Unidas.

Investigation and analysis of late reporting and under-reporting of occupational diseases from 2018 to 2020 in China / 中华劳动卫生职业病杂志

Objective: To understand the late reporting and the under-reporting of occupational disease from 2018 to 2020 in China and analyze the causes, so as to provide scientific evidence for improving the quality of occupational disease reports in China, timely acquiring the incidence of occupational disease, and assessing the occupational hazards. Methods: From May to December 2021, A total of 320 occupational disease diagnostic institutions were selected for investigation. The original documents of occupational disease diagnosis cases from 2018 to 2020 were compared with the online reported cases, and late reported and under-reported cases of occupational disease were analyzed. Results: A total of 32207 diagnosed cases from 2018 to 2020 were investigated, including 28934 confirmed cases and 3273 cases without occupational disease. The overall late reported rate and under-reported rate of confirmed cases were 20.2% and 2.1%, respectively. There were significant differences in the rate of late reporting and under-reporting of occupational diseases in different regions and different types of diagnostic institutions (P<0.001). The southwest region had the highest rates of late reporting and under-reporting, 61.6% and 7.9% respectively. The late reported rate of all kinds of occupational diseases was about 15.0%, and the under-reported rate was from 1.5.0% to 5.0%. Conclusion: At present, the phenomenon of late reporting and under-reporting occupational diseases is still obvious. It is necessary to strengthen the inspection of occupational disease reporting, improve the quality of occupational disease reporting, and provide scientific basis for the formulation of occupational disease prevention and control policies.

Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.

41 cases of chronic obstructive pulmonary disease caused by occupational irritating chemicals / 中华劳动卫生职业病杂志

Objective: To analyze the case characteristics of Chronic obstructive pulmonary disease caused by occupational irritant chemicals (OI-COPD). To provide basis for revising its diagnostic criteria. Methods: From June to December 2021, we investigated the information of OI-COPD patients confirmed by Shandong Institute of Occupational Health and Prevention of Occupational Diseases, Guangxi Zhuang Autonomous Region Institute of Occupational Disease Prevention and Control, Qingdao Central Hospital affiliated to Qingdao University and other diagnostic institutions in the past five years, a total of 41 cases. The basic information of OI-COPD cases, occupational risk factors exposure information, medical history, smoking history and clinical symptoms were analyzed retrospectively. The measurement data were tested for normal distribution, which was described by x±s, and compared between groups by t test; Those who do not conform to the normal distribution are described by the median [M (Q(1), Q(3)) ] and analyzed by nonparametric test; The counting data were expressed in frequency and rate (% ), and the comparison between groups was tested. Results: Of the 41 cases, 33 were male and 8 were female. The age of the patient diagnosed with OI-COPD was (49.5±10.3) years old, and the minimum age was 30 years old; Among them, 8 patients had a definite long-term smoking history (more than 5 years) ; The exposure duration of occupational risk factors was (18.6±10.3) years, of which 3 patients had exposure duration of less than 5 years; The occupational risk factors leading to OI-COPD include acids and acid-forming compounds, bases, aldehydes, nitrogen oxides, chlorine and its compounds, etc. The exposure level of occupational risk factors is related to the degree of COPD airflow restriction (χ(2)=6.17, P <0.05). 18 patients with diagnosis age <50 years old were diagnosed as early-onset COPD. The incidence of respiratory symptoms in the early diagnosis COPD group was lower than that in the non-early diagnosis COPD group, and the FEV1% pred was significantly higher than that in the non-early diagnosis COPD group. The difference was statistically significant (P<0.01 ) . Conclusion: The exposure level of occupational risk factors may be the risk factor affecting the degree of COPD airflow restriction. With the increase of the exposure level of COPD patients, the proportion of respiratory symptoms will also increase accordingly.

Research on early warning model of the hearing loss of workers exposed to noise / 中华劳动卫生职业病杂志

Objective: To explore the change of hearing threshold of workers exposed to noise, establish an individual-based hearing loss early warning model, accurately and differentiated the health of workers exposed to noise. Methods: In September 2019, all physical examination data of 561 workers exposed to noise from an enterprise were collected since their employment. Three indicators of average hearing threshold of the better ear, namely, at high frequency, 4000 Hz and speech frequency, were constructed. The generalized estimating equation (GEE) was used to adjust gender and age and establish the warning model of each indicator. Finally, sensitive indicators and warning models were screened according to AUC and Yoden index. Results: Among the 561 workers exposed to noise, 26 (4.6%) workers had hearing loss. The sensitivity indicators were the average hearing threshold at speech frequency ≥20 dB, high frequency ≥30 dB and 4000 Hz ≥25 dB. The AUC of each index was 0.602, 0.794 and 0.804, and the Youden indexes were 0.204, 0.588 and 0.608, respectively. In GEE of hearing loss warning models, high-frequency hearing threshold ≥20 dB and 4000 Hz hearing threshold ≥25 dB were the optimal models, with AUC of 0.862. Conclusion: Combined with the changes of individual hearing threshold over the years, can accurately assess the risk of individual hearing loss of workers exposed to noise.
