Prevalence Of Self-reported Musculoskeletal Disorders Research Articles

The prevalence and risk factors of work related musculoskeletal disorders among electronics manufacturing workers: a cross-sectional analytical study in China

ObjectivesTo describe the prevalence of self-reported musculoskeletal disorders among workers in the electronics manufacturing industry and to investigate the relations between work-related musculoskeletal disorders (WMSDs) and work-related variables.MethodsAn interview-based questionnaire survey was carried out in thirty electronics manufacturing factories in China in 2018. The prevalence of WMSDs was estimated using the modified Nordic Musculoskeletal Questionnaire (NMQ). A multivariate logistic regression model was applied to evaluate the effects of risk factors on WMSDs on multiple body parts.ResultsThe 12-month prevalence of WMSDs among participants was 40.6%, and the common body sites affected were the neck (26.8%), shoulder (22.8%), upper back (14.9%), and lower back (14.8%). The results of logistic regression showed that female adults, > 5 job tenure and work-related factors (including awkward posture, lifting or carrying weights, excessive repetition, prolonged sitting, monotonous work and working under conditions of cold or temperature variations) led to a higher risk of WMSDs on most body parts. Upper back, wrist/hand and elbow pain levels were significantly higher for workers with vibration. However, more frequently, physical exercise was a protective factor against WMSDs on most body parts except the upper back, leg and knee.ConclusionsThe study indicates a high prevalence of musculoskeletal pain among the electronics manufacturing industry in China. Different personal and work factors are related to the occurrence of WMSD on different body parts. Preventive measures should be implemented based on the characteristics of WMSD in the electronic manufacturing industry. Furthermore, the training and intervention guidance of ergonomic hazards in the workplace need to be strengthened by understanding the impact of bad posture, avoiding long-term sitting posture and increasing physical activities.

PREVALENCE AND RISK FACTORS OF SELF-REPORTED MUSCULOSKELETAL DISORDERS AMONG LOW RESOURCED URBAN COMMUNITY DWELLERS

Background: Musculoskeletal disorders are prevalent in communities across the world and their impact is affecting people in almost all occupational settings. Aim: The aim of this study was to determine the prevalence of self-reported musculoskeletal disorders among urban dwellers, Kano metropolis. Method: A total of 206 participants were recruited using a stratified sampling technique in a cross-sectional survey. The data was collected using a standard Nordic Musculoskeletal Questionnaire (NMQ) and International Physical Activity Questionnaire (IPAQ) to measure work-related musculoskeletal disorders and physical activity levels of the participants. Results: The results showed that the majority of the participants (63.9%) were males and 36.9% were females between the ages of 18 and 65 years, with the majority of them between 18 and 34 years, singles and self-employed. Also, the majority of the participants had moderate physical activity levels, normal body mass index and low risk of cardiovascular diseases using the waist to hip ratio classifications. About 78.2% of the participants reported 12-month musculoskeletal disorders while 37.4% reported 7-day musculoskeletal disorders. Low back was the most common site affected by 45.6% of the respondents. Also, the result showed no significant relationship between 12-month musculoskeletal disorder and BMI, physical activity level and waist/hip ratio but a relationship between 7 Days musculoskeletal disorder and BMI, physical activity level and waist/hip ratio. Conclusion: It was concluded that there was a high prevalence of musculoskeletal disorders among urban community dwellers in Kano metropolis, with low back pain the most reported while upper back has the least prevalence. Clinical Rehabilitation Impact: There was a high prevalence of WMSD among the general populace irrespective of the sociodemographic affiliations. Lower back was the most reported anatomical site among our participants. Men had a higher number of WMSD than women. There was an association between WMSD and WHR and BMI. Excess weight management might be helpful especially in individuals with high BMI and WHR.

Prevalence of self-reported musculoskeletal disorders of the hand and associated conducted therapy approaches among dentists and dental assistants in Germany.

BackgroundDental professionals are subjected to higher risks for musculoskeletal disorders (MSDs) than other professional groups, especially the hand region. This study aims to investigate the prevalence of hand complaints among dentists (Ds) and dental assistants (DAs) and examines applied therapies.MethodsFor this purpose, an online questionnaire analysed 389 Ds (240female/149male) and 406 DAs (401female/5male) working in Germany. The self-reported data of the two occupational groups were compared with regard to the topics examined. The questionnaire was based on the Nordic Questionnaire (self-reported lifetime, 12-month and 7-day MSDs prevalence of the hand, the conducted therapy and its success), additional occupational and sociodemographic questions as well as questions about specific medical conditions.Results30.8% of Ds affirmed MSDs in the hand at any time in their lives, 20.3% in the last twelve months and 9.5% in the last seven days. Among DAs, 42.6% reported a prevalence of MSDs in the hand at any time in their lives, 31.8% in the last 12 months and 15.3% in the last seven days. 37.5% of the Ds and 28.3% of the DAs stated that they had certain treatments. For both, Ds and DAs, physiotherapy was the most frequently chosen form of therapy. 89.7% of Ds and 63.3% of DAs who received therapy reported an improvement of MSDs.ConclusionAlthough the prevalence of MSDs on the hand is higher among DAs than among Ds, the use of therapeutic options and the success of therapy is lower for DAs compared to Ds.

Ergonomic practices and musculoskeletal disorders among ophthalmologists in India: An online appraisal

Ergonomics in ophthalmology is neither taught during professional training nor does it readily receive consideration or priority in clinical practice. Owing to a high prevalence of musculoskeletal disorders among ophthalmologists, ergonomic awareness, and practices are vital in averting this modern epidemic. To assess the ergonomic practices and prevalence of self-reported musculoskeletal disorders among ophthalmologists in India. An online survey was conducted among ophthalmologists who were registered with the All India Ophthalmological Society of India using a pre-tested and validated questionnaire. The prevalence of self-reported musculoskeletal disorder in the 377 participants was 75.3% (284; 95% confidence interval: 70.6-79.5). Low back pain (149, 52.9%) was the most commonly reported symptom. Musculoskeletal disorder-attributed productivity loss was reported by 58.45% (166) of the respondents. Musculoskeletal disorder was most frequently associated with less than 10 years of work experience (odds ratio: 1.2; 95% confidence interval: 1.1-1.3, p = 0.01) and lack of good clinic (odds ratio: 1.7; 95% confidence interval: 1.1-2.7, p = 0.03) and operation room ergonomic practices (odds ratio: 1.8; 95% confidence interval: 1.1-2.9, p = 0.03). Only 27.9% (105) of the respondents had accessed information related to ergonomics in ophthalmic practice. The self-reported musculoskeletal disorder among ophthalmologists in India is quite high and significant enough to cause some degree of productivity loss. It is thus imperative to emphasize the implementation of good ergonomic practices, especially among relatively young ophthalmologists.

Resumo Objetivo Estimar a prevalência de doenças musculoesqueléticas autorreferidas por idosos segundo variáveis demográficas, dor, autoavaliação de saúde e quedas. Métodos Estudo transversal, de base populacional, com amostra probabilística de 934 idosos residentes em Goiânia, em Goiás. Aplicou-se um questionário padronizado e semiestruturado. Considerou-se doença musculoesquelética autorreferida pelo idoso como variável desfecho, enquanto as variáveis de exposição foram demográficas, autoavaliação de saúde, quedas, dor e atividade física. Para análise, foram utilizados os testes qui-quadrado ou Fisher e regressão de Poisson (valor de p<0,05). Resultados Dos 934 idosos, 62,2% eram mulheres, com média de 71,4 anos (±8,3). A prevalência de doenças musculoesqueléticas foi de 39,1% (IC95% 35,9-42,3), sendo as mais frequentes: osteoporose (24,6%), artrose (2,9%), reumatismo (1,2%) e artrite (0,6%). A prevalência foi superior nas mulheres (44,7%; p=0,000); faixa etária ≥80 anos (44,7%; p=0,002); autoavaliação de saúde ruim (55,9%; p=0,000); relato de dor (43,4%; p=0,001). Não houve associação entre doenças musculoesqueléticas e quedas (p=0,671) e sedentarismo (p=0,167). Conclusão Observaram-se elevada prevalência de doenças musculoesqueléticas nos idosos de elevada faixa etária e associação com autoavaliação de saúde ruim e relato de dor, o que sugere intervenções no controle das condições de saúde gerais.

Distúrbios osteomusculares autorreferidos entre os trabalhadores da limpeza urbana

Objetivou-se avaliar a prevalência autorreferida de distúrbios osteomusculares entre os trabalhadores da limpeza urbana. Foi realizado estudo descritivo, de prevalência com abordagem quantitativa, tendo sido realizado no município de Patos – PB com 38 agentes da limpeza urbana local (60,1% do universo de pesquisa). A coleta de dados foi realizada entre os meses de setembro a outubro a partir da aplicação de dois questionários. O primeiro contemplou variáveis sociais, demográficas, profissionais e clínicas dos pesquisados e o segundo foi o instrumento validado denominado de Questionário Nórdico de Sintomas Osteomusculares. Os dados foram analisados no Statistical Package for the Social Sciences, versão 21 e realizou-se estatística descritiva e inferencial (correlação não paramétrica Spearman e a correlação bisserial por ponto). Aceitou-se como estatisticamente significativo um p < 0,05. Constatou-se que a prevalência autorreferida de sintomas osteomusculares foi de 45,9% (n=18), haja vista tais trabalhadores relataram a presença de dor, formigamento e dormência no corpo nos últimos 12 meses, com maior acometimento na região lombar (10,5%). Também, 15,8% (n=6) relataram impedimento de realizar atividades normais nos últimos 12 meses em decorrência destes problemas, bem como consultaram profissional de saúde nos últimos 12 meses por problemas osteomusculares e tiveram algum problema osteomuscular nos últimos sete dias. Os achados indicaram significativa prevalência autorreferida de distúrbios osteomusculares entre os agentes da limpeza urbana. O quadro demanda intervenções no campo da promoção da saúde no trabalho.

A systematic review of musculoskeletal disorders among school teachers

BackgroundMusculoskeletal disorders (MSD) represent one of the most common and most expensive occupational health problems in both developed and developing countries. School teachers represent an occupational group among which there appears to be a high prevalence of MSD. Given that causes of MSD have been described as multi-factorial and prevalence rates vary between body sites and location of study, the objective of this systematic review was to investigate the prevalence and risk factors for MSD among teaching staff.MethodsThe study involved an extensive search of MEDLINE and EMBASE databases in 2011. All studies which reported on the prevalence and/or risk factors for MSD in the teaching profession were initially selected for inclusion. Reference lists of articles identified in the original search were then examined for additional publications. Of the 80 articles initially located, a final group of 33 met the inclusion criteria and were examined in detail.ResultsThis review suggests that the prevalence of self-reported MSD among school teachers ranges between 39% and 95%. The most prevalent body sites appear to be the back, neck and upper limbs. Nursery school teachers appear to be more likely to report suffering from low back pain. Factors such as gender, age, length of employment and awkward posture have been associated with higher MSD prevalence rates.ConclusionOverall, this study suggests that school teachers are at a high risk of MSD. Further research, preferably longitudinal, is required to more thoroughly investigate the issue of MSD among teachers, with a greater emphasis on the possible wider use of ergonomic principles. This would represent a major step forward in the prevention of MSD among teachers, especially if easy to implement control measures could be recommended.
