RESUMO
Objective: To analyze the current status of work-related musculoskeletal disorders (WMSDs), work fatigue and musculoskeletal pain in Chinese occupational population, and to study the relationship between work fatigue and musculoskeletal pain and WMSDs. Methods: A total of 66 961 employees from 323 enterprises in 15 key industries in China were selected as the study subjects using stratified cluster sampling method. The incidence of WMSDs in the past year was investigated using the Chinese version of the Musculoskeletal Disorders Questionnaire, and the work fatigue and musculoskeletal pain were investigated using Borg 6-20 Rating of Perceived Exertion Scale and visual analogue scale. The data were standardized using the age composition data of 18 to 60 years from the seventh national population census. Results: The standardized annual incidence of WMSDs was higher in the front-line workers than that in the administrative and other supportive staff (38.82% vs 36.30%). The detection rates of work fatigue and musculoskeletal pain in the study subjects were 44.54% and 63.08%, respectively. The result of S-curve fitting showed that the risk of WMSDs increased with the level of work fatigue (P<0.01). Among the front-line workers, the average of monthly fatigue frequency in the neck, shoulder, lower back, upper back, wrist/hand, foot and ankle, knee, leg, and elbow were higher in the group with WMSDs compared to those without WMSDs (all P<0.01). The pain degree of musculoskeletal pain was higher in all nine sites in the fatigued group than in the no-fatigue group (all P<0.01). The standardized detection rate of musculoskeletal pain was higher in the fatigued group than in the non-fatigued group (80.38% vs 25.71%). The work fatigue was moderate and positively correlated with musculoskeletal pain in all seven sites except the lower back and elbow, with Kendall Tau-b correlation coefficients ranging from 0.423 to 0.546 (all P<0.01). Conclusion: There is a good correlation between work fatigue and local musculoskeletal pain, work fatigue and WMSDs in Chinese occupational population. Implementing ergonomic interventions to control the development of work fatigue can be an effective measure for preventing WMSDs.
RESUMO
Objective:To explore the influence of vibration operation on occupational psychological behavior of workers.Methods:From May to August 2021, a total of 384 workers from 20 factories in a city of Guangdong Province were selected as the research objects.According to the workers whether engaged in vibration operations, they were divided into the vibration group and the control group.There were 229 workers in the vibration group and 155 workers in the control group.The occupational stress scale, job burnout scale and job fatigue symptom scale were used for questionnaire survey, and IBM SPSS 24.0 software was used for statistical description and data analysis, and t-test was used for comparison of independent samples between the two groups, one-way ANOVA was used for comparison of means between multiple groups, and LSD test was used for further pin-pide comparison. Results:In the vibration group, the scores of cognitive behavioral stress(3.78±1.79), psychological stress response(4.15±2.29), physical stress(2.81±1.65) and total stress (10.74±5.11) were higher than those of the control group ((2.23±1.23), (2.30±1.62), (1.81±1.07), (6.34±2.88), t=9.31, 8.67, 6.68, 9.72, all P<0.01), and job burnout scale of emotional exhaustion (8.95±3.62), depersonalization (3.24±2.16) were higher than the control group ((5.37±2.72), (1.79±1.20), t=10.48, 7.59, both P<0.01). The score of personal achievement (26.20±2.47) was lower than that of control group ((29.73±2.52), t=13.64, P<0.01). In the job fatigue symptom scale of sleepiness (8.38±1.52), emotional restlessness (6.85±1.74), displeasure (6.38±1.57), sluggishness (8.94±2.05), visual fatigue (7.83±1.95), and total score (38.37±6.56) were higher than those of the control group ((7.89±1.29), (6.21±1.32), (5.61±1.29), (6.54±1.52), (6.67±2.02), (32.92±5.56), t=3.26, 3.90, 5.00, 12.45, 5.61, 8.48, all P<0.01)). There were significant differences in scores of occupational stress, occupational burnout and occupational fatigue symptom among different seniority groups (all P<0.01). The scores of occupational stress, job burnout and job fatigue symptoms of workers in 6-10 years and more than 10 years of service group were higher than those in 0-5 years of service group, and the differences were statistically significant ( P<0.05). Length of service was correlated with occupational stress, job burnout and job fatigue.There was a correlation between the scores of all dimensions and total score of the occupational stress scale and the scores of all dimensions of occupational burnout scale ( r=-0.67-0.63, P<0.01), as well as the scores of all dimensions and total score of the occupational fatigue symptom scale ( r=0.26-0.73, P<0.01). The direct effect of occupational stress on job fatigue was 0.417, and the mediating effect of occupational stress on job fatigue through job burnout was 0.127. Conclusion:Vibration work can lead to occupational stress, job burnout and job fatigue, which is an important factor affecting occupational psychology and occupational behavior.
RESUMO
Introducción:El aislamiento social por Covid-19 llevó a muchos colaboradores a realizar trabajo en casa y asimismo a experimentar diversas sensaciones que conjugadas con factores laborales, demandas físicas, emocionales y/o mentales, presentaron fatiga laboral,y por ende consecuencias en su salud. Objetivo:El estudio se centró en identificar síntomas relacionados a la fatiga laboral en personas con modalidad de trabajo en casa por COVID-19. Materiales y métodos:Estudio cuantitativo con un enfoque descriptivo-transversal. Se aplicó de manera virtual una escalade fatiga laboral,bajo consentimiento informado a 511 participantes que realizaban trabajo en casa. Resultados:De acuerdo con los resultados se evidenció que el 47,7% experimentaron un nivel de fatiga medio, en dimensiones relacionadas con carga física, carga mental, efectos psicofisiológicos y percepción de cambios en las dinámicas de trabajo; experiencias negativas asociadas a la insatisfacción laboral y afectación de la salud. Por otro lado, se identificaron experiencias positivas: compartir en familia, autonomía laboral y aprendizajes.Conclusiones:Se evidenció la presencia de fatiga laboral en más de la mitad de la muestra, manifestada en síntomas asociados a las diferentes dimensiones,percibidos de manera regular por los participantes,que de no ser tratados puede llegar a afectarles la calidad de vida.
Introduction:The social isolation triggered by the COVID-19 pandemic forced employees to work from home and experience diverse feelings, which together with labor factors as well as physical, emotional, and/or mental demands, led to work fatigue and in turn, to health consequences. Objective:This study was aimed at identifying symptoms related to labor fatigue in people working from home due to COVID-19. Materials and methods: A quantitative study with a descriptive-cross sectional approach. Data was collected from 511participants who worked at home using a labor fatigue virtual scale and the informed consent. Results:47.7% of participants experienced a medium fatigue level, in dimensions such as physical load, mental load, psycho-physiological effects, and perceptionof changes in job dynamics. Likewise, they reported negative experiences associated with job dissatisfaction and health issues. On the other hand, positive events were identified, such as sharing time with family, job autonomy, and learning experiences. Conclusions: Work related fatigue was evidenced in half of the participants, which was expressed through symptoms associated with different dimensions. They were perceived frequently and may affect the quality of life of participants if these symptoms are not treated properly.

Fadiga no trabalho é a percepção individual de desconforto físico, cognitivo e emocional, associada com sentimentos de perda de energia, cansaço e exaustão, levando a efeitos deletérios no desempenho laboral. O objetivo do presente trabalho foi adaptar e levantar evidências psicométricas para o contexto brasileiro do Three-Dimensional Work Fatigue Inventory (3D-WFI). O estudo foi conduzido com 455 trabalhadores adultos, oriundos de três contextos ocupacionais (segurança pública, saúde e população geral). Entre estes 251 eram do sexo masculino. Os dados analisados a partir de procedimentos fatoriais confirmatórios e multigrupo apontaram adequação ao modelo original de três dimensões de fadiga (física, cognitiva e emocional). Indicadores de precisão foram bons e superiores a 0,91 em todas as dimensões resultantes. Evidências externas do 3D-WFI foram observadas com engajamento no trabalho, satisfação com a vida e conflito trabalho-família. Discutem-se aplicações do instrumento para o contexto de pesquisa e diagnóstico nas organizações.
Work fatigue is the individual's perception of physical, cognitive, and emotional discomfort, associated with feelings of energy loss, tiredness, and exhaustion, leading to deleterious effects on work performance. This study aimed to adapt and raise psychometric evidence for the Brazilian context of the Three-Dimensional Work Fatigue Inventory (3D-WFI). The study was conducted with 455 adult workers from three occupational contexts (public safety, health, and general population). Among these, 251 were male. The data analyzed using confirmatory factorial and multigroup procedures indicated the original three-dimensional fatigue model (physical, cognitive and emotional). Accuracy indicators were good and above 0.91 in all resulting dimensions. External evidence of 3D-WFI was observed with work engagement, life satisfaction, and work-family conflict. Applications of the instrument for the context of research and diagnosis in organizations are discussed.
