RESUMO

This study was conducted to describe the health conditions (the psychosocial aspects, sleep quality, and musculoskeletal symptoms) among Brazilian healthcare workers in the context of the pandemic. Workers answered an online questionnaire, including the short version of the Copenhagen Psychosocial Questionnaire (COPSOQ II), the Pittsburgh Sleep Quality Index (PSQI), the Nordic Musculoskeletal Questionnaire (NMQ), and the Beck Depression Inventory (BDI). The most unfavourable psychosocial factors were work pace (61%; 95% CI: 52-69%), emotional work demands (75%; 95% CI: 67-82%), predictability (47%; 95% CI: 39-56%), work-family conflict (55%; 95% CI: 46-64%), burnout (86%; 95% CI: 78-91%), and stress (81%; 95% CI: 73-87%). Most workers (74%; 95% CI: 66-81%) were classified as poor sleepers. Musculoskeletal symptoms were frequent in the neck (64%; 95% CI: 55-72%), shoulders (62%; 95% CI: 54-70%), upper back (58%; 95% CI: 50-67%), and lower back (61%; 95% CI: 52-69%). Depressive symptoms were also highly prevalent (mild: 22%; 95% CI: 15-30%, moderate: 16%; 95% CI: 11-23%, severe: 8%; 95% CI: 4-14%). Most healthcare workers experience unfavourable psychosocial factors, poor sleep quality, as well as musculoskeletal and depressive symptoms. These findings underscore the urgent need to acknowledge and address psychological and physical distress to improve the personal and professional well-being of this population.

RESUMO

BACKGROUND: Overuse injuries result from the cumulative process of repetitive microtrauma and overload on the musculoskeletal system, which causes tissue damage. Therefore, these injuries may have long-term negative consequences that decrease an athlete's performance. OBJECTIVE: To estimate the prevalence of overuse injuries in individual and team sports. METHODS: Searches on MEDLINE, EMBASE, SPORTDiscus, and CINAHL from the first registration to February 2021 and hand-searching identified studies investigating the prevalence of overuse injuries in athletes from individual and team sports. Meta-analysis was conducted and the GRADE system summarized the overall quality of evidence. This review was registered in PROSPERO (CRD42019135665). RESULTS: Seventeen studies were included and pooling of 24 704 participants (22 748 of individual sports and 1.956 of team sports). Data from point- and period-prevalence of overuse injuries in individual and team sports were obtained. Pooled period-prevalence of overuse injuries in individual and team sports was 42.0% (95% CI: 30.0, 55.0) and 33.0% (95% CI: 21.0, 49.0), respectively. Another four studies investigated point-prevalence. The overall quality of evidence for the period-prevalence was of moderate quality. Sensitivity analyses suggested that different joints based in individual and team sports tended to increase the estimated prevalence of overuse injuries. CONCLUSION: Athletes, clinicians, sport teams, and policymakers should be aware of the high prevalence of overuse injuries in athletes, especially, in athletes from individual sports. Current moderate-quality evidence shows that future high-quality studies are likely to impact on the estimated prevalence.

RESUMO

Temperature gradient changes on the surface of the skin or in the middle of the body are signs of a disease. The aim of this study is to develop quantitative models for the prediction of cumulative trauma disorders (CTDs) arising from highly repetitive activities, considering risk factors, such as age, gender, body mass index (BMI), blood pressure (BP), respiratory rate (RR), and heart rate, to prevent injuries in manufacturing factory operators. This research involved 19 individuals from the area of sanding and 14 individuals from the area of tolex in manufacturing factories who had their vital signs and somatometry taken, as well as thermal images of their hands in the dorsal and palmar areas; an evaluation by the OCRA method was also applied. Factors such as BP and heart rate were determined to significantly influence the injuries, but no strong association with BMI was found. Quadratic regression models were developed, the estimates of which were adequately adjusted to the variable (R2 and R2 adjusted > 0.70). When integrating the factors of the OCRA method to the generated models, a better fit was obtained (R2 and adjusted R2 > 0.80). In conclusion, the participants who present levels out of the normal range in at least one of the factors have high probabilities of developing injuries in their wrists.

RESUMO

INTRODUÇÃO: Os distúrbios osteomusculares relacionadas ao trabalho são patologias muito frequentes no meio industrial, principalmente quando os trabalhadores se encontram expostos a fatores de risco como, por exemplo, posturas inadequadas, repetitividade, uso de força excessiva e a exposição a vibrações. OBJETIVO: Avaliar o risco de distúrbios osteomusculares nos punhos de trabalhadores de uma indústria de pescados da cidade de Recife (PE). METODOLOGIA: Utilizou-se metodologia qualitativa baseada no método Strain Index (SI), o qual resulta em uma pontuação numérica que aponta a probabilidade de desenvolvimento de distúrbios osteomusculares no punho. O índice é baseado na pontuação do SI, representado pela interação multiplicativa entre as variáveis da tarefa: intensidade do esforço, duração do esforço, frequência do esforço, postura da mão e punho, ritmo de trabalho e duração diária da tarefa. RESULTADOS: O valor encontrado foi de SI = 9 para ambos os punhos, classificando-o como uma atividade com alto risco para o desenvolvimento de distúrbios osteomusculares nos punhos dos trabalhadores. CONCLUSÃO: A indicação da presença dos riscos desses distúrbios nos punhos durante a realização da atividade de trabalho foi determinada pela pontuação do SI, sugerindo a necessidade de intervenção ergonômica.

INTRODUCTION: Cumulative trauma disorders are very common diseases in industry, especially when workers are exposed to risk factors such as, for example, inappropriate postures, repetitive, excessive use of force and vibration exposure. OBJECTIVE: To assess the risk of musculoskeletal disorders in the wrists of industrial workers caught in the city of Recife, Pernambuco State, Brazil. METHODOLOGY: We used a qualitative methodology based on the method Strain Index (SI) which results in a numerical score that indicates the risk of developing musculoskeletal disorders in the wrist. The index is based on the SI score is represented by the multiplicative interaction between the task variables: intensity of exercise, exercise duration, frequency of stress, the hand and wrist posture, pace of work and daily duration of the task. RESULTS: The value found was SI = 9 for both fists, classifying it as a risky activity for the development of musculoskeletal disorders in the wrists of workers. CONCLUSION: The indication of the presence of the risks of these disorders in the wrists during the course of work activity was determined by the SI score, pointing to the need for ergonomic intervention.
