ABSTRACT
Los trastornos músculo-esqueléticos relacionados con el trabajo constituyen motivo de preocupación para la comunidad científica, avalado por su efecto negativo en la vida de los trabajadores y la productividad de las empresas. En el proceso de fundición de metales, los moldeadores manuales con pisón neumático exteriorizan manifestaciones de estas afecciones. Ello indujo a realizar una investigación que tuvo como objetivo elaborar un programa de Gimnasia Laboral para contribuir a la atención de los trastornos músculo-esqueléticos en los moldeadores manuales metalúrgicos. Para recopilar, analizar y procesar los datos se emplearon métodos teóricos, empíricos y matemático-estadísticos, entre ellos el histórico-lógico, analítico-sintético, inductivo-deductivo, sistémico-estructural-funcional, la observación participante, encuesta, entrevista, revisión documental, el experimento, criterio de usuarios y la estadística descriptiva e inferencial. La población objeto de estudio estuvo conformada por 19 moldeadores manuales metalúrgicos, seleccionados de forma intencional. El diagnóstico y la sistematización teórica alcanzada posibilitaron elaborar un programa de Gimnasia Laboral, en correspondencia con los requerimientos del proceso de moldeo, cuya efectividad fue constatada.
As lesões músculo-esqueléticas relacionadas com o trabalho são motivo de preocupação para a comunidade científica, sustentadas pelos seus efeitos negativos na vida dos trabalhadores e na produtividade das empresas. No processo de fundição do metal, os moldadores manuais com compactador pneumático externalizam as manifestações dessas condições. Isso originou uma pesquisa que teve como objetivo desenvolver um programa de Ginástica Laboral para contribuir no cuidado de lesões osteomusculares em moldadores manuais metalúrgicos. Para coletar, analisar e tratar os dados foram utilizados métodos teóricos, empíricos e matemático-estatísticos, incluindo histórico-lógico, analítico-sintético, indutivo-dedutivo, sistêmico-estrutural-funcional, observação participante, levantamento, entrevista, revisão documental, o experimento, critérios de usuário e estatísticas descritivas e inferenciais. A população em estudo foi composta por 19 modeladores manuais metalúrgicos, selecionados intencionalmente. O diagnóstico e a sistematização teórica conseguidos permitiram desenvolver um programa de Ginástica Laboral, em correspondência com as exigências do processo de moldagem, cuja eficácia foi verificada.
Work-related musculoskeletal disorders are a cause of concern for the scientific community, supported by their negative effect on the lives of workers and the productivity of companies. In the metal casting process, manual molders with pneumatic tamper externalize manifestations of these conditions. This led to carrying out a research that aimed to develop a Labor Gymnastics program to contribute to the care of musculoskeletal disorders in metallurgical manual shapers. To collect, analyze and process the data, theoretical, empirical and mathematical-statistical methods were used, including historical-logical, analytical-synthetic, inductive-deductive, systemic-structural-functional, participant observation, survey, interview, documentary review, the experiment, user criteria and descriptive and inferential statistics. The population under study was made up of 19 metallurgical manual shapers, intentionally selected. The diagnosis and theoretical systematization achieved made it possible to develop a Labor Gymnastics program, in correspondence with the requirements of the molding process, whose effectiveness was verified.
ABSTRACT
Objective@#To investigate the prevalence of work-related musculoskeletal disorders (WMSDs) and influencing factors among vegetable greenhouse workers, so as to provide insights into relevant intervention measurements.@*Methods@#Workers from 4 vegetable greenhouse villages were sampled in the suburbs of Xining City using a cluster sampling method from March to April 2023. Participants' demographic information, characteristics of greenhouse operation and prevalence of WMSDs were collected using questionnaire surveys. Factors affecting the prevalence of WMSDs among vegetable greenhouse workers were identified using a multivariable logistic regression model.@*Results@#A total of 550 questionnaires were distributed, and 518 valid questionnaires were recovered, with an effective response rate of 94.18%. There were 264 males (50.97%) and 254 females (49.03%), and 269 participants (51.93%) aged 50 years and older. The prevalence of WMSDs among vegetable greenhouse workers was 40.93% (212 cases). Waist, neck and back were mainly affected, with 185 (35.71%), 157 (30.31%), and 153 (29.54%) cases, respectively. Multivariable logistic regression analysis showed that workers who smoke (OR=2.406, 95%CI: 1.133-5.110), worked 8 hours and longer per day (OR=6.618, 95%CI: 3.492-12.542) and lift heavy loads of about 20 kg (OR=1.770, 95%CI: 1.013-3.092) had a higher risk of WMSDs.@*Conclusions@#WMSDs occurred in 40.93% of vegetable greenhouse workers in Xining City, and waist, neck and back were mainly affected. Smoking, working duration and lifting heavy loads may influence the prevalence of WMSDs among vegetable greenhouse workers in Xining City.
ABSTRACT
ObjectiveTo explore the effect of occupational stress on work-related musculoskeletal disorders (WMSDs) in electronics manufacturing workers. Methods A total of 392 front-line workers in two electronic manufacturing enterprises in Guangdong Province were selected as the research subjects using the judgment sampling method. The prevalence of WMSDs and the level of occupational stress of the research subjects were investigated using the Musculoskeletal Disorders Questionnaire and the Core Occupational Stress Scale. Results The total WMSDs detection rate was 39.5%, and the multi-site WMSDs detection rate was 30.6%. The detection rate of occupational stress was 14.8%. The total WMSDs detection rate and multi-site WMSDs detection rate in the occupational stress group were higher than those in the non-occupational stress group (65.5% vs 35.0%, 56.9% vs 26.0%, both P<0.01). Binary logistic regression analysis result showed that the risk of WMSDs in the occupational stress group was higher than that in the non-occupational stress group after adjusting the effect of confounding factors such as age, gender, job type and work days per week (P<0.01). Conclusion The occupational stress may increase the risk of WMSDs in electronics manufacturing workers. Reducing the level of occupational stress among workers in electronic manufacturing enterprises is beneficial for reducing the risk of WMSDs.
ABSTRACT
ObjectiveTo explore the impact of overtime work on work-related musculoskeletal disorders in male employees in the automobile manufacturing industry. Methods A total of 1 731 male employees with more than one year of working experience from an automobile manufacturing industry were selected as the research subjects using judgment sampling method. The Musculoskeletal Disorder Questionnaire was used to investigate the prevalence of musculoskeletal disorder. Employees were divided into control group and overtime group, and a 1∶1 matching was performed using propensity score matching method, and 573 pairs were successfully matched. The prevalence of WMSDs in various body parts was compared between the two groups. Results The overtime working rate of the research subjects was 34.2%, and the prevalence of WMSDs was 57.1%. Overtime work increased the risk of WMSDs in the neck, shoulders, upper back, lower back, ankle/feet, and overall body of the workers (all P<0.05), with the odd ratio and 95% confidence interval of 1.43 (1.10-1.85), 1.38 (1.06-1.80), 1.42 (1.07-1.89), 1.28 (1.01-1.62), 1.37 (1.01-1.87), and 1.49 (1.17-1.89), respectively. However, there was no association between overtime work and the risk of WMSDs in the elbows, hands/wrists, hips, and knees of the subjects (all P>0.05). Conclusion Overtime work increases the risk of WMSDs in the neck, shoulders, upper back, lower back, ankles/feet, and overall body of male employees in the automobile manufacturing industry. Enterprises should improve labor organization, reduce overtime work, and protect the health of workers.

ABSTRACT
Objective To investigate the influence of individual factors and labor organization factors on work-related musculoskeletal disorders (WMSDs) in automobile manufacturing workers, and to provide a scientific basis for the prevention and treatment of WMSDs in automobile manufacturing workers. Methods In April 2020, 5564 workers in an automobile factory were selected by cluster sampling method. The prevalence of WMSDs was investigated by using the Musculoskeletal Disorders Questionnaire, and the influence of individual factors and labor organization factors on WMSDs was investigated by using generalized estimation equation. Results The prevalence rate of WMSDs was 79.00% (4396/5564), and the prevalence rate of multisite WMSDs was 67.95% (3781/5564). The analysis of generalized estimation equation showed that doing the same job every day (OR= 1.478, P 40 hours per week increased the risk of WMSDs (P< 0.05). Male and adequate rest time were protective factors for WMSDs. The job correlation matrix showed that WMSDs in most parts had a positive correlation. Conclusions The prevalence of multisite WMSDs of workers in automobile manufacturing industry is high, and unreasonable labor organization is the main risk factor of WMSDs. Appropriate work breaks can effectively reduce the risk of WMSDs, and effective intervention measures should be carried out to prevent the occurrence of WMSDs in workers in automobile manufacturing industry. The generalized estimation equation can better analyze the influencing factors of WMSDs.
ABSTRACT
Background With the rapid development of China's express delivery industry, small parcel couriers generally report overtime, excessive intensity, and high work load, and are at a high risk of developing work-related musculoskeletal disorders (WMSDs). Using questionnaires to conduct research on WMSDs-associated postures may contain unavoidable subjectivity, and the simulation methods can quantitatively evaluate WMSDs, boasting advantages such as high efficiency and low cost, and become a research development trend. Objective To conduct ergonomic evaluation of typical postures of express couriers handling small parcels using a simulationmethod. Methods SolidWorks software was used to establish a geometric model of a parcel (530 mm depth × 290 mm width × 370 mm height), a geometric model of an express carriage (1.4 m depth × 0.9 m width × 1.17 m height), and a geometric model of a delivery truck (1.7 m height). These models were imported into Jack software, and the weight of parcel was set at 20 kg. The digital model of a male express courier was established in Jack software. A typical parcel handling task was defined as standing on one side of the express carriage and bimanually placing parcels at four different heights (top, upper half, middle, and bottom of the carriage) combined with three horizontal positions (outer side, center, and inner side of the carriage). The visual field and reach zones tools in Jack software were used to determine whether the parcels can be seen and touched by the express courier, and determine the operational posture of the express courier at their ends of motion ranges. The Ovako working posture analysis system (OWAS) and rapid upper limb assessment (RULA) tools in Jack software were used to evaluate postures applied at typical vertical and horizontal distances. Results The maximum horizontal and vertical gaze fields effectively covered the area where the parcels were located, but some areas were not within the optimal field of view. When the horizontal distance between the parcel and the express courier exceeded 48 cm, the express courier was not able to directly reach it and had to adjust his standing position or posture to perform the task. The OWAS analysis found that when the express item was placed at the top, upper section, or middle of the carriage, the risk level of the courier's work posture was level 1, suggesting a normal posture. When the parcel was placed at the inner side bottom of the carriage, the courier needed to bend his knees and lower back, and the highest risk level for the posture was level 3, which had harmful effects on the musculoskeletal system, and correctiveactions were required as soon as possible. The other two work postures placing the parcel elsewhere in the bottom were graded level 2, which may cause harm to the musculoskeletal system , and corrective actions were required in the near future. The RULA analysis found that the risk of the posture was level 2 for handling the parcel in the upper or middle of the carriage, and level 3 for handling the parcel at the top or bottom of the carriage. When the parcel was placed at the bottom of the carriage, as the horizontal distance between the express item and the courier increased, the risk of posture increased to level 3 or above, and the risk reached level 4 for the parcel located at the innermost side of the carriage. Conclusion There is a significant risk of WMSDs in manually handling parcels at different heights and horizontal positions. The risk levels of associated postures are elevated from low to high following the express item pleased at the middle, upper, bottom, and top of the carriage and the extension of horizontal distances, if the express item is placed at the bottom of the carriage, between the courier and the parcel. By installing doors on both sides of the express delivery carriage, it is possible for the express courier to adjust his standing position and provide a vertical motion range, ensuring best visual field and reach zones.
ABSTRACT
Abstract This article aims to estimate the prevalence of musculoskeletal disorders (MD) on the adult population of Campinas, São Paulo, Brazil, verifying associated demographic and socioeconomic factors, and to analyze their impact on Health-Related Quality of Life (HRQoL) according to sex. A population-based study was conducted with 2,166 individuals using data from the ISACamp 2014/15. The Medical Outcomes Study SF-36-Item Short Form Health Survey (SF-36) was used to measure HRQoL according to MD. Prevalence ratios (PR) were estimated by Poisson regression. Musculoskeletal disorders had a prevalence of 8.5% (6.7% tendonitis and 2.7% work-related musculoskeletal disorders - WMSD). Results showed a higher prevalence of musculoskeletal disorders in women, active or on leave due to illness, and in individuals with higher education levels. Moreover, reduced HRQoL scores were observed in 6 of the 8 domains, due to MD. The mental component and physical component showed greater impairment respectively among women and men after self-reported WMSD. These findings point to substantial damage from musculoskeletal disorders on the population's HRQoL. WMSD affect the HRQoL of men and women distinctly.
Resumo O objetivo deste artigo é estimar a prevalência de doenças musculoesqueléticas (DM) na população adulta de Campinas/SP, Brasil, verificar fatores demográficos e socioeconômicos associados e analisar o seu impacto na qualidade de vida relacionada à saúde (QVRS) segundo sexo. Este é um estudo de base populacional utilizando dados do ISACamp 2014/15, com 2.166 indivíduos. Para a medida de QVRS, foram calculados os escores médios do Short Form Health Survey 36 (SF-36) segundo as DM e utilizada a regressão de Poisson para estimar as razões de prevalência (RP). A prevalência de DM foi de 8,5% (6,7% de tendinite e 2,7% de doenças osteomusculares relacionadas ao trabalho - DORT). Os resultados deste estudo mostraram maior prevalência de DM em mulheres, na população adulta ativa ou afastada por doença e em indivíduos com maior escolaridade. Além disso, observou-se redução nos escores de QVRS, devido às DM, em quase todos os domínios do instrumento. O maior comprometimento foi observado no componente mental entre as mulheres, e no componente físico, entre os homens, após autorrelato de DORT. Os achados mostram o impacto substancial das DM na QVRS da população. As DORT afetam distintamente a QVRS de homens e mulheres.

ABSTRACT
Abstract Introduction Although teleworking emerged decades before the COVID-19 pandemic, the spread of the virus in 2020 resulted in faster and more widespread implementation of this work format. However, the lack of a dedicated workspace may pose ergonomic risks and increase the incidence of musculoskeletal disorders. Objective Understand the risks of repetitive strain injury (RSI) and work-related musculoskeletal disorders (WMSDs) in teleworking from the perspective of employees at a public university. Methods A list of employees at a public university who were full or part-time teleworkers was obtained from the campus Personnel Department and used to select subjects for individual scripted interviews. The interviews were recorded and transcribed for thematic content analysis. Results Eight employees took part in the interviews, most of whom were women, aged between 33 and 64 years and from different professional categories. The interviewees reported ergonomic deficiencies, musculoskeletal symptoms, using individual preventive strategies, and the advantages of teleworking, among others. Conclusion There are still ergonomic-related risks of RSI/WRMDs, and despite changes made during the COVID-19 pandemic, it remains important to comply with preventive needs and improve knowledge management among workers.
Resumo Introdução O teletrabalho surgiu décadas antes da pandemia. Em 2020, porém, com a propagação do vírus da COVID-19, esse modo de trabalho foi implementado de forma rápida e mais ampla. A falta de um ambiente dedicado ao teletrabalho, contudo, pode promover riscos ergonômicos e consequentemente uma maior ocorrência de distúrbios osteomusculares. Objetivo Compreender os riscos de lesões por esforços repetitivos (LER) e distúrbios osteomusculares relacionadas ao trabalho (DORT) no teletrabalho a partir da percepção de servidores de uma universidade pública. Métodos Obteu-se uma listagem de servidores da Divisão de Gestão com Pessoas de um campus de uma universidade pública que estavam em teletrabalho (parcial ou total) e selecionaram-se sujeitos para a realização de entrevistas individuais, com base em roteiro elaborado. As entrevistas foram gravadas e transcritas para análise temática de conteúdo. Resultados Participaram das entrevistas oito servidores, a maioria do sexo feminino, com idade entre 33 e 64 anos e de diversas categoriais profissionais. Nas entrevistas, surgiram inadequações ergonômicas, sintomas osteomusculares, utilização de estratégias individuais de prevenção, vantagens do teletrabalho, entre outros. Conclusão Ainda existem aspectos ergonômicos de risco para LER/DORT e, apesar das adaptações feitas ao longo da pandemia de COVID-19, ainda há necessidade de atender às necessidades de prevenção e melhorar a gestão de conhecimento para os trabalhadores.
ABSTRACT
Resumo Objetivo: investigar os efeitos de intervenções no ambiente laboral para prevenção de distúrbios musculoesqueléticos. Métodos: revisão sistemática que incluiu ensaios randomizados, individuados ou comunitários, que investigaram efeitos de intervenções no trabalho para prevenir distúrbios musculoesqueléticos, relatados em artigos publicados entre 2015 e 2020 e indexados nas bases de dados: Lilacs, Medline/Pubmed, PEDro e Web of Science. Os estudos foram categorizados conforme a modalidade de intervenção e avaliados quanto à qualidade metodológica. Resultados: dos 58 estudos selecionados, 15 atenderam satisfatoriamente aos critérios de qualidade, abordando diferentes modalidades de exercícios físicos e/ou abordagem cognitivo-comportamental, aplicadas de forma única ou combinada; nenhum estudo abordou intervenções organizacionais. Apesar da heterogeneidade de intervenções e desfechos, exercícios físicos realizados nos locais de trabalho resultaram em diminuição da dor musculoesquelética, do uso de analgésicos e do afastamento do trabalho por distúrbios musculoesqueléticos, no entanto, combinados às intervenções comportamentais não mostraram os resultados esperados. Os resultados com a Ergonomia Participativa ratificaram o papel fundamental dos trabalhadores na realização de intervenções em seus ambientes de trabalho. Conclusão: apesar de benefícios observados, salienta-se que os estudos revisados não produziram evidências consolidadas acerca das intervenções mais eficazes para prevenir distúrbios musculoesqueléticos entre trabalhadores.
Abstract Objective: to investigate the effects of workplace interventions aiming to prevent musculoskeletal disorders. Methods: systematic review that included randomized, individual or community trials, which investigated the effects of workplace interventions aiming to prevent musculoskeletal disorders, reported in articles published between 2015 and 2020 and indexed in the following databases: Lilacs, Medline/Pubmed, PEDro, and Web of Science. Studies were categorized according to the type of intervention and evaluated in terms of methodological quality. Results: of all 58 studies selected, 15 satisfactorily met the quality criteria, addressing different types of physical exercise and/or cognitive-behavioral approaches, applied alone or in combination. No study addressed organizational interventions. Despite the heterogeneity of interventions and outcomes, physical exercises performed in the workplace led to reduction in musculoskeletal pain, use of analgesics, and absence from work due to musculoskeletal disorders; however, combined with behavioral interventions, they did not show the expected results. The results with participatory ergonomics confirmed the critical role of workers in performing interventions in the workplace. Conclusion: despite the benefits observed, the studies reviewed did not produce consolidated evidence about the most effective interventions to prevent musculoskeletal disorders among workers.
ABSTRACT
Resumen Antecedentes: Los trastornos musculoesqueléticos (TME) afectan a 1710 millones de personas en todo el mundo y es la principal causa de discapacidad. Objetivo: Analizar los años vividos con discapacidad (AVD) por TME en México entre 1990 y 2021. Material y métodos: Con las estimaciones del estudio de la Carga Global de la Enfermedad 2021 se analizaron los AVD por TME y sus seis categorías: osteoartritis, artritis reumatoide, gota, dolor cervical, lumbalgia y otros TME. Se evaluaron patrones y tendencias del número, tasa cruda y tasa estandarizada por edad de los AVD a nivel nacional, estatal, por grupos de edad y sexo. Resultados: Los TME constituyeron la principal causa de AVD en México entre 1990 y 2021, con un incremento de 57.3 %; pasaron de 1458.4 a 2293.7 por 100 000 habitantes. La lumbalgia (840.6 AVD) destacó con la mayor tasa en 2021 y la osteoartritis, con el mayor incremento. Los TME se incrementaron con la edad y, con excepción de la gota, afectaron más a las mujeres. Conclusiones: De 1990 a 2021, los TME constituyeron la principal causa de AVD en México, con mayor impacto en adultos y mujeres. Los TME se evidencian desde edades tempranas, de ahí la necesidad de intervenciones continuas para preservar la calidad de vida.
Abstract Background: Musculoskeletal disorders (MSD) affect 1.71 billion people worldwide and are the leading cause of disability. Objective: To analyze the years lived with disability (YLD) attributed to MSD in Mexico between 1990 and 2021. Material and methods: With estimates from the Global Burden of Disease 2021 study, the YLDs due to MSD and their six categories were analyzed, including osteoarthritis, rheumatoid arthritis, gout, neck pain, low back pain, as well as other MSDs. Patterns and trends in the number, crude rate, and YLD age-standardized rate were evaluated at the national and state levels, as well as by age group and gender. Results: MSDs were the main cause of YLDs in Mexico between 1990 and 2021, with an increase of 57.3%, going from 1,458.4 to 2,293.7 per 100,000 population. Low back pain (840.6 YLD) showed the highest rate in 2021, while osteoarthritis had the largest increase. MSDs increased with age and, and except for gout, affected women more often. Conclusions: From 1990 to 2021, MSDs were the main cause of YLDs in Mexico, with a higher impact on adults and women. MSDs can appear early in life, hence the need for continuous interventions in order to preserve quality of life.
ABSTRACT
Background: Work-related musculoskeletal disorders (WMSDs) are emerging problems and it occurs when there is a mismatch between the physical requirements of the job and the physical capacity of the human body. Study aimed to find out the prevalence of WMSDs, the influence of varied working posture and level of physical activity (PA) for the development of WMSDs amongst the sewing machine operators. Methods: This is a cross-sectional study and conducted in a garment industry at Vapi, Gujrat. By purposive sampling technique, 100 sewing machine operators having minimum one year of experience, in the age group of 18-60 years were recruited with their consent. Örebro Musculoskeletal pain questionnaire (ÖMPQ), Rapid Entire Body Assessment tool (REBA), Quick Exposure Check tool (QEC) and International Physical Activity Questionnaire (IPAQ) was administered to all the participants. Data was analyzed using SPSS 24 software. Descriptive statistics applied for categorical variables, Spearman Rank correlation coefficient (r) was calculated for the relationship between PA and WMSDs. Results: This study revealed the prevalence of WMSDs as 70% and low back pain was the commonest complaint. REBA demonstrated that 55% of participants were at high musculoskeletal risk and 44% were at very high risk. QEC identified that neck region had very high exposure risk for the development of WMSDs. The level of PA shows no association with WMSDs (r = 0.040, p=0.62). Conclusions: Sewing machine operators of this study adopted a poor working posture which corresponds to the development of high musculoskeletal risk and an increased prevalence of WMSDs.
ABSTRACT
Introduction: Small-scale fishing is responsible for at least 40% of the fish consumed in the world. In Brazil, the worker in this sector is the artisanal fisherman, who accounts for one in every 200 Brazilians. Artisanal fishing is part of the informal economy; therefore, the pathologies that affect these fishermen are invisible in the country's official statistics. Musculoskeletal disorders represent a major socioeconomic and public health problem, but their prevalence is little known among non-formal workers. Objective: to estimate the prevalence of musculoskeletal disorders (MSDs) in the lower limbs and to verify the associated factors among artisanal fishermen/ fisherwomen from Saubara, Bahia, Brazil. Methodology: a cross-sectional study, using the Nordic Musculoskeletal Questionnaire (NMQ), the Brazilian version of the Job Content Questionnaire (JCQ) and a questionnaire about physical demands, were used to collect information in a random sample of artisanal fishermen/shellfish gatherers, in 2013. Results: the prevalence of MSDs in lower limbs in the sample was 65.5% (n=137). The prevalence of MSDs in the thigh/knee segment, leg and ankle/foot were 48.7% (n=92), 47.7% (n=95) and 38.1% (n=72), respectively. There was also a high frequency of obesity, poor education, low wages, early age at onset of labor, and excessive workload. Factors such as age, smoking, physical demands, working time, absence of breaks and having had a previous job were associated with MSDs in the lower limbs. Conclusion: the high prevalence of MSDs in lower limbs in female artisanal fishermen indicates the need to develop strategies for prevention, diagnosis and reporting of these diseases.
Introdução: a pesca em pequena escala é responsável por pelo menos 40% do pescado consumido no mundo e, no Brasil, o trabalhador desse setor é o pescador artesanal, que contabiliza um a cada 200 brasileiros. Por se tratar de uma atividade da economia informal, as patologias que afetam esses pescadores são praticamente invisíveis nas estatísticas oficiais do país. Nesse contexto, os distúrbios musculoesqueléticos representam um grande problema socioeconômico e de saúde pública, mas sua prevalência é pouco conhecida entre trabalhadores não formais. Objetivo: estimar a prevalência de distúrbios musculoesqueléticos nos membros inferiores e fatores associados, em pescadores artesanais/marisqueiras de Saubara, Bahia, Brasil. Metodologia: trata-se de um estudo transversal, utilizando o Nordic Musculoskeletal Questionnaire, a versão brasileira do Job Content Questionnaire e um questionário sobre demandas físicas, para a coleta de informações em uma amostra aleatória de pescadores artesanais/marisqueiras, ocorrida em 2013. Resultados: a prevalência de distúrbios musculoesqueléticos em membros inferiores na amostra foi de 65,5% (n=137); a prevalência no segmento coxa/joelho, perna e tornozelo/pé foi de 48,7% (n=92), 47,7% (n=95) e 38,1% (n=72), respectivamente. Observaram-se também alta frequência de obesidade, baixa escolaridade, baixos salários, idade precoce para o início do trabalho e carga horária excessiva. Fatores como idade, tabagismo, demandas físicas, tempo de trabalho, ausência de pausas e trabalho anterior, estavam associados aos referidos distúrbios. Conclusão: A alta prevalência de distúrbios musculoesqueléticos dos membros inferiores em pescadoras artesanais indica a necessidade de desenvolver estratégias de prevenção, diagnóstico e notificação dessas doenças

Background: Musculoskeletal problems are widespread in the elderly, but they are also becoming more common in the younger population as a result of changes in lifestyle and employment. In this study we will be assessing the musculoskeletal disorders in delivery personnel. Methods: 200 delivery personnel took part in an offline survey at several e-commerce companies� delivery hubs as part of this observational study, based on inclusion and exclusion criteria. In addition to questions from the Nordic Questionnaire, the form included basic demographic information. Results: The current study showed that the musculoskeletal pain in the last 12 months showed the prevalence was higher for lower back 60(30%) followed by 18(9%) for neck. The seven days prevalence showed 43(21.5%) for lower back followed by 11(5.5%) for neck. Prevention to do the work due to the pain in last 12 months showed highest percentage of the respondents experienced it due to lower back pain. The statistics further showed majority of people who had musculoskeletal pain from last 12 months were working for more than 8 hours per day (52.3%). Conclusions: We can conclude that MSDs are common in all three groups, namely pain in the past year, pain in the past week, and activity prevention. This incidence demonstrates that MSDs can impact delivery personnel even at younger ages, which can be avoided by reducing workload and observing adequate safety procedures while working.
ABSTRACT
Background: Work?related musculoskeletal disorders (WMSDs) are the second most common cause of disability, accounting for 17% of all Years lived with a disability (YLDs) worldwide. Healthcare professionals, especially dentists, are known to be at a higher risk of WMSDs. Therefore, this study aims to determine the point and period prevalence of WMSDs among dentists and to assess the risk factors for WMSDs, including workstation analysis. Methods: This cross?sectional study was conducted among 120 dentists from three dental colleges in Gujarat (Ahmedabad and Gandhinagar), India. A structured questionnaire was used to collect sociodemographic and occupational history along with pre?validated standardized tools such as the Nordic Musculoskeletal Questionnaire (NMQ), Rapid Entire Body Assessment (REBA) score sheet and Quick Exposure Checklist (QEC). Data analysis was performed using SPSS version 20. Results: The period prevalence of MSDs and WMSDs were 85% and 75.8% respectively, and the point prevalence was 39.2% and 23.3% respectively. Prosthodontists reported the highest prevalence of WMSDs. The neck (64.7%) was the most commonly affected area. A statistically significant result was obtained between MSDs and BMI (P = 0.02), qualification (P = 0.01) and between WMSDs and duration of work in the sitting posture (P = 0.03). Conclusions: The prevalence of both MSDs and WMSDs was found to be high. Dentists with higher BMI, higher qualifications, lack of breaks, having poor workstations and higher REBA and QEC scores, whose job tasks involve continuous inspection, frequent bending of elbow joints, frequent repetitive motions, tasks that require them to reach distances greater than 20 inches and tasks that involve twisting of the waist are at a higher risk of developing MSDs
ABSTRACT
Work-related musculoskeletal disorders (WMSDs) are chronic and cumulative disorders that are affected by multiple ergonomic factors. They are widespread in occupational populations and have a high prevalence. They have caused a substantial economic and social burden, which has become a major occupational health problem worldwide. The mechanism of WMSDs needs to be clarified. More authoritative and unified diagnostic criteria and specific therapeutic drugs are required. Therefore, an in-depth epidemiological investigation on WMSDs involving occupational ergonomics is of great scientific value and practical significance, which aims to improve hazard identification and ergonomic load risk assessment and to facilitate the prevention, control, and intervention of WMSDs. This article introduced the concept, status report, risk factors, ergonomic assessment methods, and preventive measures of WMSDs. This special column on "occupational ergonomics and work-related musculoskeletal disorders" presented the prevalence and related risk factors of WMSDs in different industries, as well as working condition simulation studies for specific tasks, aiming to provide objective and detailed scientific data for the prevention and control of WMSDs.
ABSTRACT
Background Furniture manufacturing is one of the typical labor-intensive industries, and workers in this industry face a high risk of work-related musculoskeletal disorders (WMSDs), which seriously affect the physical and mental health of workers. Objective To explore the prevalence and potential risk factors of WMSDs among workers in a large-scale furniture manufacturing factory. Methods A cross-sectional study of 3431 workers in a furniture factory in Guangdong Province was conducted from September to December 2019. Information including reported WMSDs in various body parts in the past year, demographic characteristics, work organization factors, job characteristics, and work postures was collected by an electronic version of Musculoskeletal Disorders Questionnaire. Pearson χ2 test and binary logistic regression were used to analyze the risk factors leading to WMSDs. Results The overall prevalence rate of WMSDs was 32.12% (1102/3431). The most common WMSDs symptoms occurred in the neck (16.85%), followed by the feet (15.27%), shoulders (14.81%), and hands (14.25%). The prevalence rates of WMSDs in the neck, shoulders, elbows, hands, legs, and feet were significantly different among different types of work (P<0.05). The results of multiple logistic regression analysis showed that individual factors, work organization factors, job characteristics, and awkward work postures were associated with the frequency of reporting WMSDs in specific parts of workers. Comparatively poor physical health (including moderate, poor, and very poor) was positively correlated with neck, shoulder, hand, and foot WMSDs (OR=1.479-4.077); working with an uncomfortable posture (OR=1.983) and doing the same task almost every day (OR=1.783) were positively correlated with neck pain; doing the same task almost every day (OR=2.408) and neck twisting for a long time (OR=1.830) were positively correlated with shoulder pain; bending wrists up and down frequently (OR=1.948) and bending wrists for a long time (OR=2.081) were positively correlated with hand pain; prolonged standing (OR=1.953) and often working overtime (OR=1.627) were positively correlated with feet pain; sufficient rest time was negatively correlated with WMSDs in the neck, shoulders, hands, and foot (OR=0.544-0.717). Conclusion The prevalence rate of WMSDs in furniture manufacturing workers is relatively high, and neck, feet, shoulders, and hands are the most involved body parts. The frequency of reporting WMSDs is related to individual factors, work organization factors, job characteristics, and awkward work postures.
ABSTRACT
Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.
