Abstract Background: Police training is considered high risk and demands physical and mental vigor from the worker before preforming the service. Therefore, sleep quality is important as it directly impacts the health of these workers in several aspects. Furthermore, the lack of sleep quality due to work can negatively influence the quality of life outside of work. Aim: To analyze the influence of sleep quality on the quality of life and work of military police officers. Methods: A quantitative, cross-sectional correlational study, conducted in the first half of 2019 with police officers from three municipalities in Bahia, Brazil. Three instruments were used: sociodemographic and work characteristics; quality of life at work; and sleep quality. The chi-square test was applied for sociodemographic and occupational variations. Subsequently, the Spearman correlation test was applied between sleep quality and the quality of life and work dimensions. Results: Among the 298 police officers the median age was 40 years and the length of service was ≤ 7 years. It was also observed that police officers with poorer sleep quality had an unsatisfactory quality of life at work in all its dimensions (biological/physiological; psychological/behavioral; sociological/relational; economic/political, environmental/organizational). Conclusion: Police officers suffer from poor sleep quality and this negatively influence their quality of life and work. Therefore, there is a need to develop actions in the workplace that may reduce the risks of health problems caused by poor sleep quality.

Voice Disorder, Job Stress, and COVID-19 in Teachers: Impacts in Times of Pandemic

Introduction: The conditions of teachers' work during the COVID-19 pandemic affected teachers' lives regarding voice disorder and stress, even in emergency remote classroom situation. Objective: To analyze the relationship between the presence of voice disorder, job stress, and COVID-19 in teachers when in emergency remote classroom teaching situation at the time of the pandemic. Method: This is a primary, exploratory, observational cross-sectional study with the use of survey forwarded online during the period of emergency classes after the arrival of COVID-19 pandemic in Brazil. The teachers answered the sociodemographic questions about the presence of COVID-19 and the following instruments: Condition of Vocal Production-Teacher [Condição de Produção Vocal - Professor (CPV-P)], Screening Index for Voice Disorder (SIVD), and Job Stress Scale (JSS). Results: Of the 118 teachers analyzed, 94.1% were female; the average age was 44 years. The SIVD recorded the presence of voice disorder in 66.9% of the participants. Regarding the JSS, which are the findings related to stress at work in the demand domain, the teachers showed high levels, a fact which presupposes the existence of pressure of psychological nature to perform their work. Conclusion: The teachers self-reported the presence of voice disorder even in remote class situation, on the occasion of COVID-19, which were more common in older teachers. When comparing the presence of voice disorders, coronavirus symptoms, and stress domains in relation to demand, control, and social support, there was no significance. It is hoped that this study will help to reflect on the need to improve teachers' working conditions, strengthening work-related voice disorder actions and guiding actions for vocal care and well-being.

Introducción: Las condiciones de trabajo de los profesores durante la pandemia de COVID-19 afectaron sus vidas en lo que respecta al trastorno de la voz y el estrés, incluso en situaciones de emergencia en aulas remotas. Objetivo: Analizar la relación entre la presencia de trastorno de la voz, estrés laboral y COVID-19 en profesores cuando se encontraban en situación de emergencia de enseñanza en aulas remotas en la época de la pandemia. Método: Se trata de un estudio primario, exploratorio, observacional de tipo transversal, con el uso de encuesta remitida online durante el periodo de clases de emergencia tras la llegada de la pandemia de COVID-19 en Brasil. Los profesores respondieron a las preguntas sociodemográficas sobre la presencia de COVID-19 y a los siguientes instrumentos: Condición de Producción Vocal-Profesor (CPV-P), Índice de Detección de los Trastornos de la Voz (SIVD) y Escala de Estrés Laboral (JSS). Resultados: De los 118 profesores analizados, el 94,1% eran mujeres; la mediana de edad era de 44 años. El (SIVD) registró la presencia de trastorno de la voz en el 66,9% de los participantes. En cuanto a la JSS, que son los hallazgos relacionados con el estrés laboral en el dominio de la demanda, los profesores mostraron niveles elevados, hecho que presupone la existencia de presiones de naturaleza psicológica para realizar su trabajo. Conclusión: Los profesores autoinformaron de la presencia de trastornos de la voz incluso en situación de clase a distancia, con ocasión del COVID-19, que fueron más frecuentes en los profesores de más edad. Al comparar la presencia de trastornos de la voz, los síntomas del coronavirus y los dominios de estrés en relación con la demanda, el control y el apoyo social, no hubo resultados significativos. Se espera que este estudio ayude a reflexionar sobre la necesidad de mejorar las condiciones de trabajo de los docentes, fortaleciendo las acciones de Trastorno de la voz relacionado con el trabajo (WRVD) y orientando acciones para el cuidado y bienestar vocal.

Behind the Headset: Predictive Accuracy of Patient-Reported Outcome Measures for Voice Symptoms in Call Centers

Objective: This study examines factors predicting self-reported voice symptoms in call center workers. Methods: Multivariate analysis and predictive modeling assess personal, work-related, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Receiver Operating Characteristic (ROC) curves are employed. Results: Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symptom complexity in call center professionals, necessitating comprehensive assessment. Limitations: This study recognizes its limitations, including a moderate-sized convenience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value: This research provides novel insights into the interplay of personal, occupational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of individual susceptibility to voice disorders. Conclusion: Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behaviors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.

Objetivo: Este estudio examina los factores que predicen los síntomas de voz en los trabajadores de call centers. Métodos: Se utilizan análisis multivariados y modelos predictivos para evaluar factores personales, laborales, acústicos y de comportamiento. Se emplean Modelos Lineales Generalizados (GLM) y curvas ROC. Resultados: La edad y los patrones de sueño afectaron la calidad vocal y el esfuerzo, mientras que los factores laborales influyeron en la percepción de síntomas. Los comportamientos vocales no saludables se relacionaron con voz tensa y mayor esfuerzo, mientras que la hidratación fue protectora. Los parámetros acústicos de voz mostraron potencial diagnóstico respaldado por datos de ROC. Los hallazgos subrayan complejidad de síntomas vocales en profesionales de centros de llamadas, requiriendo una evaluación integral. Limitaciones: Este estudio reconoce sus limitaciones, que incluyen una muestra de conveniencia de tamaño moderado y la dependencia de medidas PROMs. Futuras investigaciones deberían incorporar medidas objetivas, además de los autorreportes y análisis acústico. Importancia: Esta investigación aporta nuevos conocimientos sobre factores personales, laborales y síntomas de voz en trabajadores de call centers. El modelado predictivo mejora la evaluación de riesgos y la comprensión de la susceptibilidad individual a trastornos de la voz. Conclusión: Los resultados muestran asociaciones entre diversos factores y los síntomas vocales reportados. Los factores de protección incluyen dormir más de seis horas y una hidratación constante; los factores de riesgo incluyen las condiciones de trabajo, como la ubicación y comportamientos como fumar. Los modelos de diagnóstico indican una buena precisión para algunas PROMs de síntomas de la voz, lo que subraya la necesidad de modelos integrales que tengan en cuenta los factores laborales, los comportamientos vocales y los parámetros acústicos para comprender la complejidad de los problemas de la voz.

Vocal Load of University Professors: Preliminary Results

Purpose: To describe the acoustic characteristics of a classroom, voice quality, fatigue, and vocal load of university professors. Methods: Exploratory, observational, longitudinal, and descriptive study with a single group of participants, including vocal monitoring data over two weeks. Acoustic characterization of the classroom, perceptual-auditory evaluation, and acoustic analysis of voice samples were conducted before and after classes. Vocal dosimetry was performed during classes, and the Vocal Fatigue Index (VFI) was assessed at the beginning of each week. Descriptive analysis of the findings was conducted, and randomization test was performed to verify the internal reliability of the judge. Results: All participants reported speaking loudly in the classroom, with the majority reporting vocal changes in the past six months, and only one participant reported a current vocal change. The classroom had acoustical measures and estimations that deviated from established standards. The professors used high vocal intensities during classes. After the classes, an increase in the absolute values of the aggregated data for CAPE-V, jitter, and fundamental frequency was found, varying within the range of normality. Furthermore, there was an observed increase in both post-lesson intensity and VFI when comparing the two-week period. Conclusions: Vocal intensities and VFI were possibly impacted by the acoustics of the classroom. The increase in average VFI between the weeks may be attributed to a cumulative fatigue sensation. Further research with a larger number of participants and in acoustically conditioned classrooms is suggested in order to evaluate collective intervention proposals aimed at reducing the vocal load on teachers.

Objetivo: Describir las características acústicas, calidad vocal, fatiga y carga vocal de profesores universitarios. Métodos: Estudio exploratorio, observacional, longitudinal, descriptivo con un solo grupo de participantes y datos de monitoreo vocal durante dos semanas. Se realizó caracterización acústica de la sala, evaluación auditiva-perceptiva y acústica de muestras de voz antes y después de las clases. Se realizó dosimetría vocal durante las clases y se verificó el Índice de Fatiga Vocal (IFV) en dos semanas. Se realizó un análisis descriptivo de los hallazgos y una prueba de aleatorización para verificar la confiabilidad interna del juez. Resultados: Todos los participantes informaron hablar en voz alta en clase, la mayoría informó cambios vocales en los últimos seis meses y solo uno informó cambios vocales actuales. La sala presentó mediciones y estimaciones acústicas fuera de las normas establecidas. Los profesores utilizaron intensidades vocales altas durante las clases. Hubo un aumento en los valores absolutos de los datos agrupados para CAPE-V, jitter y frecuencia fundamental, variando dentro de los límites normales, después de las clases. La intensidad después de las clases y el IFV, en la comparación entre las dos semanas, mostraron un aumento. Conclusiones: La dosis vocal y el IFV posiblemente se vieron afectados por la acústica del aula. El aumento del IFV medio entre semanas pudo deberse a la sensación de cansancio acumulada. Se sugieren nuevas investigaciones con un mayor número de participantes y que se realicen en la sala acondicionada acústicamente para evaluar propuestas de intervención colectiva, con el objetivo de reducir la carga vocal de los docentes.

Application and comparison of three risk assessment methods for occupational health risk assessment of dust in a sanitary ceramic product manufacturing enterprise / 上海预防医学

ObjectiveThree methods were applied to conduct occupational health risk assessment for the working positions exposed to silicon dusts in a sanitary ceramic manufacturing factory， and the evaluation results were compared to explore the applicability of different occupational health risk assessment methods. MethodsOne large sanitary ceramic product manufacturing enterprise in Songjiang District， Shanghai was selected to conduct occupational health risk assessment for the working positions exposed to silicon dusts， using occupational hazard risk index evaluation method， exposure ratio evaluation method， and International Council on Mining and Metals （ICMM） quantitative occupational health risk assessment method . The consistency of the evaluation results of the three methods was tested using weighted Kappa method. ResultsFourteen working positions exposed to silicon dusts were identified， and three positions had excessive dust concentration： composite forming position of phase 2 workshop （0.80 mg·m-3）， addition forming position of phase 2 workshop （1.00 mg·m-3）， and glazing position of 1F in phase 2 workshop （1.50 mg·m-3）， with an excessive rate of 21.42%. The occupational hazard risk index evaluation method assessed 6 positions with no harm， 6 positions with mild harm， and 2 positions with moderate harm. The ICMM quantitative occupational health risk assessment method assessed 6 positions with potential risks， 2 positions with tolerable risks， and 6 positions with intolerable risks. The exposure ratio evaluation method assessed 8 positions with medium risk， 5 positions with high risk， and 1 position with extremely high risk. The consistency test results of the three evaluation methods were poor. The Kappa coefficient between the occupational hazard risk index evaluation method and the ICMM quantitative occupational health risk assessment method was 0.15. The Kappa coefficient between the occupational hazard risk index evaluation method and the exposure ratio evaluation method was -0.09. The Kappa coefficient between the ICMM quantitative occupational health risk assessment method and the exposure ratio evaluation method was 0.04. The RR values obtained by the three evaluation methods were significantly correlated： the correlation coefficients between RRICMM quantitative assessment method and RRexposure ratio evaluation method， RROccupational hazard risk index evaluation method and RRICMM quantitative assessment method， RROccupational hazard risk index evaluation method and RRexposure ratio evaluation method were 0.915， 0.604， and 0.594， respectively. The correlation between the assessment result level and CTWA was strong. ConclusionThe occupational hazard risk index evaluation method is suitable for the working positions with low silicon dust exposure concentration， the ICMM quantitative occupational health risk assessment method and the exposure ratio evaluation method are suitable for the positions with high silicon dust exposure concentration， but all these three evaluation methods have limitations. It is more reasonable to use multiple methods at the same time in actual evaluation work.

Occupational health management of radiation workers in non-medical institutions in Shanxi Province, China / 中国辐射卫生

Objective To understand the basic information of the number, classification, and distribution of radiation work units in non-medical institutions in Shanxi Province, China, and to analyze the status quo of health management and radiation protection measures for radiation workers, so as to provide a scientific basis for occupational exposure protection in non-medical radiation work units and better protect the occupational health rights and interests of radiation workers. Methods A questionnaire survey was conducted to investigate some non-medical institutions in Shanxi Province. On-site testing was carried out to determine the risk factors for radioactive occupational diseases in the selected non-medical institutions. Results In 220 non-medical institutions, there were 340 radiation devices and 2284 radioactive sources. The rate of individual dose monitoring was 92.7% and the rate of occupational health examination was 87.2%. These devices were equipped with 325 detection instruments for radiation protection, 1316 personal protective equipment, and 730 personal dose alarms. Radiation occupational disease risk factors were investigated in 101 institutions. Conclusion The occupational health management of radiation workers in non-medical institutions in Shanxi Province is generally in line with the national standards. However, there is still a big gap with the level of occupational health management in medical institutions. The health administration departments should clarify the management measures for non-medical institutions and strengthen their supervision and management functions.

Objective To investigate the current status of radiation protection in non-medical radiation workplaces in Yantai, China, and to provide a scientific basis for occupational health management in non-medical radiation workplaces. Methods Non-medical radiation workplaces in Yantai were investigated using a questionnaire survey in 2022, including radiation source term, occupational health examination, personal dose monitoring, personal protective equipment, and radiation protection testing workplaces. Data were entered by a double-entry method and then analyzed. Results There were 56 non-medical radiation workplaces in Yantai, covering manufacturing, nonferrous metal ore mining, nuclear power plant, transportation, and technical services. There were 0 Class I radiation device, 150 Class II radiation devices, and 10 Class III radiation devices; there were 80 Class I radiation sources, 16 Class II radiation sources, 14 Class III radiation sources, 62 Class IV radiation sources, and 135 Class V radiation sources. There were 998 radiation workers, with an occupational health examination rate and personal dose monitoring rate of 98.3%. Among the 56 non-medical radiation workplaces, 47 (83.9%) were equipped with radiation protection monitoring instruments, 24 (51.1%) workplaces had verified the radiation protection monitoring instruments, with 2017 personal dose monitoring instruments and 2327 personal protective equipment in place, 42 (75%) workplaces carried out occupational health assessments, 44 (78.6%) workplaces carried out self-detection, and 53 (94.6%) workplaces carried out entrusting detections (monitoring pass rate: 100% [53/53]). The declaration rate of occupational hazard items was 87.5% (49/56). Conclusion There is still a gap between the current status and the requirements in the national regulations and standards regarding radiation protection in non-medical radiation workplaces. Therefore, the supervision and management of non-medical radiation workplaces should be further strengthened, especially the configuration and verification of radiation protection monitoring instruments.

Health status of photovoltaic module production workers in Shanghai / 环境与职业医学

Background Photovoltaic (PV) cells can convert solar energy into electricity and alleviate the dilemma of energy supply shortage. Shanghai's PV module industry is booming, but there are few reports on the health status of the workers and there is an urgent need for health risk assessment. Objective To evaluate the health status of PV module production workers and the association between work and health status, in order to provide a direction for the health management of the workers. Methods Among the PV module production workers who completed prescriptive occupational health examination by a designated medical institution in 2021, 2453 workers with more than one year of working age were selected as the exposure group and 538 newly hired workers as the control group. On the basis of the Technical specifications for occupational health surveillance (GBZ 188−2014), the health examination included physical examination and laboratory examination and information such as sociodemographics, living habits, and disease history. We compared the indicators of pure-tone hearing test, blood routine examination, electrocardiogram (ECG), liver function, and kidney function between the two groups. The blood routine results included erythrocyte-related indicators, leukocyte-related indicators, and platelet-related indicators, and the results of liver function included hepatocyte injury indicators, hepatic secretory function indicators, and hepatic synthesis function indicators. The workers were divided into four groups by quartiles of working age. Trend chi-square test was used to analyze differences in health status between the four working age groups. Multiple logistic regression models were used to evaluate the association between working age and health indicators. Results Among the exposure group workers, 2035 (83.0%) were male and 418 (17.0%) were female. The median (P25, P75) age was 34.0 (30.0, 39.0) years and the median (P25, P75) working age was 6.0 (3.0, 10.0) years. The abnormality rate of blood routine was 61.7%. Among them, the abnormality rates of platelet-related indicators and liver secretory function indicators were 39.8% and 48.1% respectively. The risks of abnormal hepatocyte injury-related indicators, fatty liver, and platelet-related indicator abnormalities among the exposure group were 1.471 (95%CI: 1.060, 2.054), 1.691 (95%CI: 1.208, 2.385), and 7.576 (95%CI: 4.967, 11.994) times higher than those in the control group respectively. The single-factor analysis demonstrated a positively linear trend between working age and hypertension prevalence, electrical audiometry abnormality rate, or liver secretory function indicator abnormality rate. Corrected for gender, age, smoking status, hypertension, etc., the results of logistic analysis showed that quartile working age was positively related to abnormal liver secretion function and abnormal platelet-related indicators respectively (OR=1.047, P=0.005; OR=1.037, P=0.014), and inversely associated with the abnormal rate of renal function (OR=0.953, P=0.044). Conclusion Negative associations between health status and working age are identified in PV module production workers. The target PV module production employees are in younger age, and with the increase of working age, the abnormalities of liver function and platelets may increase. Therefore, the enterprises should extend occupational health work from workplace to workers.

Abstract Objective To analyze the role of formal and informal social support in the practice of physical activity during workers' leisure time. Methods A cross-sectional study carried out with 395 technical administrative workers at a public university. Data were collected using sociodemographic questionnaire, Baecke Habitual Physical Activity Questionnaire and Physical Activity and Social Support Scale. Data were analyzed using descriptive statistics, Student's t test, Cohen's d test and Analysis of Variance. Results Participants who reported some type of support for physical activity in their leisure time (92.2%) had higher means in the physical activity score. Institutional support (58.0%) had a prominent role as a potential influencer compared to support from immediate superiors (14.2%), although they had a certain differential among maintenance workers. Conclusion Social support plays an important role in promoting physical activity in workers' leisure time. Institutional initiatives to encourage active behavior in the work environment need to be aligned with encouragement by immediate superiors so that they are more effective.

Efeitos combinados de gênero, raça e estressores ocupacionais na saúde mental / Combined effects of gender, race, and occupational stressors on mental health

Resumo Objetivo: analisar os efeitos isolados e combinados do gênero, da raça e dos estressores ocupacionais sobre a saúde mental de trabalhadores e trabalhadoras da saúde. Métodos: estudo transversal com amostra aleatória de trabalhadores(as) da saúde da Bahia, Brasil. As variáveis de exposição principais foram: gênero, raça e estressores ocupacionais, avaliados por meio da escala de Desequilíbrio Esforço-Recompensa (DER). O Self-Reporting Questionnaire (SRQ-20) mensurou os transtornos mentais comuns (TMC), variável desfecho. As medidas de interação foram verificadas com base no critério da aditividade, pelo cálculo do excesso de prevalência, excesso de razão de prevalência e diferença relativa. Resultados: participaram 3.343 trabalhadores, 77,9% do sexo feminino. A prevalência de TMC foi 21,7% maior entre mulheres, negros e pessoas em situações de exposição aos estressores laborais. Entre as mulheres negras em situação de DER, a prevalência de TMC foi três vezes maior em relação aos homens brancos em situação de equilíbrio (grupo de referência). Discussão: trabalhadoras negras acumulam desvantagens sociais e estão mais suscetíveis a ocupações de maior esforço e menor recompensa. A prevalência de TMC foi superior na intersecção das exposições. O efeito combinado dos fatores excedeu a soma dos efeitos isolados, demonstrando interação entre gênero, raça e estressores ocupacionais.

Abstract Objective: analyze the isolated and combined effects of gender, race, and occupational stressors on the mental health of healthcare workers. Methods: cross-sectional study with a random sample of health workers in Bahia, Brazil. The primary exposure variables were gender, race, and occupational stressors, assessed using the Effort-Reward Imbalance (ERI) scale. The Self-Reporting Questionnaire (SRQ-20) measured common mental disorders (CMD), the outcome variable. The interaction measures were verified based on the additivity criterion by calculating the excess prevalence, excess prevalence ratio, and relative difference. Results: 3,343 workers participated, 77.9% were female. CMD prevalence was 21.7% higher among women, Black people, and those exposed to work stressors. Among Black women in a situation of ERI, the prevalence of CMD was three times higher compared with white men in a situation of balance (reference group). Discussion: black women workers accumulate social disadvantages and are more susceptible to occupations that require more significant effort and less reward. CMD prevalence was higher at the intersection of exposures. Combined effect of the factors exceeded the sum of the isolated effects, demonstrating an interaction between gender, race, and occupational stressors.

Conclusão: a análise revelou impactos sobre a saúde dos trabalhadores, com novos desafios para a classe trabalhadora. Tais impactos, entre outras razões, se devem a jornadas ampliadas, condições ergonômicas no domicílio e pressões para cumprimento de metas.

Abstract Introduction: with the COVID-19 pandemic and the social distancing policy, almost 9 million workers had their professional activities transferred to the home environment, called "remote work," "home office," or "telework." This context worked as a laboratory in which companies could experiment with teleworking. Objective: to analyze the unprecedented telework growth and the teleworkers' profile, highlighting the impacts and consequences for the workers' health. Methods: analysis of relevant bibliography, exploration of secondary data from empirical research on objective and subjective teleworking conditions, publications in the media about telework in the pandemic and post-pandemic context, and analysis of remote work ads. Results: due to the way remote work occurred during the pandemic, in addition to its consequences for health, and living and working conditions, new challenges were raised for the working class. Among them: how to ensure adequate environmental and ergonomic working conditions and how to guarantee the limit of working hours, and the delimitation of working time, in view of the tendency for telework to be maintained in the post-pandemic period. Conclusion: the analysis revealed impacts on workers' health that bring new challenges to the working class. Such impacts, among other reasons, are due to extended working hours, ergonomic conditions at home, and pressure to meet goals.

Mortalidade e carga do câncer de laringe atribuíveis aos riscos ocupacionais no Brasil: estudo da Carga Global de Doença, 2019 / Laryngeal cancer mortality and burden attributable to occupational risks in Brazil: 2019 Global Burden of Disease

Resumo Objetivo: descrever a mortalidade e os anos de vida ajustados pela incapacidade disability-adjusted life years - DALYs) para câncer de laringe no Brasil atribuíveis a fatores de risco ocupacionais e comportamentais. Métodos: estudo ecológico com dados do estudo Global Burden of Disease 2019. Foram obtidas taxas de mortalidade e de DALYs para o câncer de laringe atribuíveis aos riscos ocupacionais (ácido sulfúrico e amianto) e comportamentais (tabaco e álcool), de 1990 e 2019. Resultados: no Brasil, em 2019, a taxa de mortalidade por câncer de laringe atribuível aos riscos ocupacionais (ácido sulfúrico e amianto) foi 0,28 (II95%: 0,17;0,43) no sexo masculino e 0,03 (II95%: 0,02;0,04) no feminino, e a de DALYs foi 7,33 (II95%: 4,28;11,44) e 0,64 (II95%: 0,35;0,03), respectivamente. O ácido sulfúrico foi o principal risco ocupacional para a doença. Houve redução das taxas atribuíveis ao tabaco (mortalidade:-45,83%; DALYs:-47,36%) e aos riscos ocupacionais (mortalidade:-23,20%; DALYs:-26,31%), no Brasil, com aumento em alguns estados das regiões Norte e Nordeste. Conclusão: houve redução na mortalidade e na carga do câncer de laringe atribuível aos fatores ocupacionais no período, porém menor em comparação ao tabagismo, reforçando a importância de ações para reduzir o impacto dos riscos ocupacionais, como as medidas regulatórias aplicadas ao tabaco.

Abstract Objective: to describe mortality and disability-adjusted life years (DALYs) due to laryngeal cancer attributable to occupational and behavioral risk factors in Brazil. Methods: this is an ecological study with data from the 2019 Global Burden of Disease. Mortality and DALY rates for laryngeal cancer attributable to occupational (sulfuric acid and asbestos) and behavioral (tobacco and alcohol) risks were obtained from 1990 and 2019. Results: in 2019, the mortality rate from laryngeal cancer attributable to occupational hazards (sulfuric acid and asbestos) totaled 0.28 (95%UI: 0.17; 0.43) and 0.03 (95%UI: 0.02; 0.04), whereas and DALY rates, 7.33 (95%UI: 4.28; 11.44) and 0.64 (95%UI: 0.35; 0.03) in men and women in Brazil, respectively. Sulfuric acid configured the main occupational risk for the disease. The rates attributable to tobacco (mortality: −45.83%; DALYs: −47.36%) and occupational hazards (mortality: −23.20%; DALYs: −26.31%) decreased in Brazil but increased in some Northern and Northeastern states. Conclusion: laryngeal cancer mortality and burden attributable to occupational factors decreased in the period (although less than that for smoking), reinforcing the importance of actions to reduce the impact of occupational risks, such as the regulatory measures applied to tobacco.

A contribuição da Ergonomia para a segurança no trabalho / Ergonomics contribution to occupational safety

Resumo Introdução: processos de alto risco com elevadas taxas de acidentes desafiam a segurança. Por outro lado, sistemas ultrasseguros conquistaram ótimos indicadores. Em ambos, a prevenção parece ter chegado a um limite - em um deles, porque parece impotente para gerar prevenção; no outro, porque foi tão bem-sucedida que parece impossível avançar. Objetivo: evidenciar a contribuição da Ergonomia em prol da segurança, nas situações descritas, suas possibilidades ainda por explorar, entre elas a Ergonomia de concepção na integração homem-máquina (sistemas informatizados). Método: análise comparativa dos achados oriundos de estudos ergonômicos em sistemas de produção com altas taxas de acidentes e sistemas ultrasseguros. Discussão: a análise da atividade dos motofretistas mostrou que existem alternativas de ação ainda não exploradas entre as relações de trabalho desfavoráveis e a percepção de inevitabilidade dos acidentes. Nos sistemas ultrasseguros, o aparente limite pode ser superado com os avanços recentes na análise da ação e cognição situadas e na construção de espaços de debate que permitam o retorno da experiência de campo. Em sistemas informatizados, as práticas de projeto colaborativo, que se valem da experiência dos trabalhadores para alimentar as dinâmicas de aprendizagem e a confiabilidade técnica, são possibilidades ainda pouco praticadas na Engenharia de Segurança.

Abstract Introduction: while high-risk processes with high accident rates challenge safety, High Reliability Organization (HRO) achieve excellent indicators. In both cases, prevention seems to have reached a limit. In the former, because it seems powerless to generate prevention; in the latter, because it has been so successful that it seems impossible to reach greater levels. Objective: to highlight the contribution of Ergonomics to safety in these situations, pointing out unexplored possibilities such as design Ergonomics in man-machine integration (computerized systems). Method: comparative analysis of findings from ergonomic studies on production systems with high accident rates and HRO. Discussion: analysis of the motorcycle freight drivers' activity revealed alternatives yet to be explored between unfavorable work relations and the perceived inevitability of accidents. The apparent limit of HRO can be overcome with recent advances in the analysis of situated action and cognition and by building debate spaces based on field experience. Collaborative design practices, which draw on worker experience to feed learning dynamics and technical reliability, remains a poorly explored possibility in Safety Engineering when it comes to computerized systems.
