Prevalence of work related musculoskeletal disorders (WMSDs) and ergonomic risk assessment among readymade garment workers of Bangladesh: A cross sectional study

Sleep quality and nighttime sleep duration mediated the association between occupational stress and work-related musculoskeletal disorders among bus drivers

BACKGROUND

Work-related musculoskeletal disorders (WMSDs) significantly affect bus drivers' health and warrant adequate attention. Previous studies had reported associations between occupational stress exposure and WMSDs, but the underlying mechanisms remain unclear. This study aimed to evaluate the associations of occupational stress with WMSDs and the mediated effect of sleep quality and nighttime sleep duration.

METHODS

A total of 1,792 bus drivers with the available information from 5 subsidiaries of Shenzhen Bus Group were included by the convenience sampling method. Logistic regression model was used to estimate the associations of occupational stress, sleep quality and nighttime sleep duration with WMSDs. Mediation analysis was performed to explore the role of sleep quality and nighttime sleep duration in the association between occupational stress and WMSDs.

RESULTS

The prevalence rate of single-site, multiple-site, and overall WMSDs among bus drivers were 10.04%, 59.26%, and 69.31%, respectively. We found that occupational stress was significantly associated with an increased risk of both multiple-site WMSDs and overall WMSDs [OR (95% CI) = 1.92 (1.56, 2.36) and 2.03 (1.63, 2.55), respectively]. Compared to those with high sleep quality, bus drivers with poor sleep quality exhibited a higher risk of multiple-site WMSDs and overall WMSDs [OR (95% CI) = 3.73 (2.89, 4.84) and 4.82 (3.53, 6.71), respectively]. Each 1-hour increment in nighttime sleep duration was linked to a 36% declined risk of multiple-site WMSDs and a 37% reduced risk of overall WMSDs [OR (95% CI) = 0.64 (0.58, 0.71) and 0.63 (0.57, 0.70), respectively]. Moreover, mediation analysis showed that sleep quality mediated 48.94% and 48.70%, and nighttime sleep duration mediated 19.63% and 18.64%, of the associations between occupational stress and multiple-site WMSDs and overall WMSDs, respectively.

CONCLUSION

Occupational stress and poor sleep quality significantly elevated the risk of both multiple-site and overall WMSDs, while increased nighttime sleep duration was associated with a reduced risk of multiple-site and overall WMSDs. Sleep quality and nighttime sleep duration emerged as potential mediators in multiple-site and overall WMSDs induced by occupational stress. Highlighting the importance of reducing occupational stress, maintaining good sleep quality and sufficient nighttime sleep duration for WMSDs prevention.

Occupational risk factors related to musculoskeletal disorders among Praewa silk weavers in the Northeast region, Thailand

Praewa silk weavers are subject to numerous occupational risk factors that contribute to musculoskeletal disorders (MSDs), primarily due to inadequate occupational safety measures, limited access to health services, and substandard working conditions. The aim of this study was to assess the prevalence rate and determinants of MSDs among Praewa silk weavers. A cross-sectional study employing a convenience sampling method was conducted, involving 198 Praewa silk weavers from four provinces in the Northeast region of Thailand. Data collection was facilitated through a two-part research tool. The first part included a questionnaire assessment using demographic information, workplace conditions, and self-reported MSDs. The second part involved an ergonomic risk assessment using rapid upper limb assessment (RULA) and hand activity level (HAL). Descriptive statistics and multiple logistic regression analyses were conducted to determine the prevalence and associated factors of MSDs among participants. The findings revealed that the prevalence rates of MSDs in the past 7 days and 12 months were 68.68% and 96.46%, respectively. The highest prevalence rates of MSDs (over 60.00%) were observed in the wrists, fingers, and neck, with similar trends reported in both the past 7 days and 12 months. Key factors associated with MSDs over the past 12 months included low hand strength test results (adjusted odds ratio (AOR) = 2.09; 95%CI: 0.44-11.05), quite low hand strength test results (AOR=2.49; 95%CI: 0.29-21.15), weaving experience of 21-30 years (AOR=1.07; 95%CI: 0.20-5.64), age between 31-40 years (AOR=2.63; 95%CI: 0.49-13.91), age above 41 years (AOR=1.13; 95%CI: 1.08-1.19), RULA level 4 (AOR=3.62; 95%CI: 0.66-19.96), and HAL score exceeding 0.78 (AOR=0.63; 95%CI: 0.80-0.98) were significantly associated with MSDs during the past 12 months. This study highlights the high prevalence of MSDs among Praewa silk weavers, attributed to occupational risk factors such as low hand strength, high hand activity level, extensive weaving experience, and poor working posture. The weaving process itself is a significant contributor to these disorders. In conclusion, ergonomics interventions aimed at preventing MSDs, including postural training, injury prevention programs, and re-designed pull-cloth devices, are recommended to mitigate these risks.

Proof-of-concept system evaluation of Ergomechanic for non-invasive estimation of upper-body posture and body load exposure in the workplace

Ergomechanic is a software-hardware system that uses cameras, computer vision and biomechanical modelling to calculate posture and body load during physical activity in the workplace. This study evaluated its ability to non-invasively and automatically identify postures adopted by workers that could lead to injury in the long term, and to use these results to suggest focuses for safety interventions. Five participants were recruited to perform normal duties in an area that was in view of four off-the-shelf security cameras. Participants were randomly assigned to the work area and 60 h of footage were collected. Five metrics relating to potential for injury were calculated for each second of footage. The extreme values of each metric were used to automatically identify body positions and work activities that could be hazardous in the long term. Insights from the process were used to recommend changes to the work area and activity design.

Prevalence of musculoskeletal disorders among garment workers: a systematic review and meta-analysis

BACKGROUND

Garment workers are at high risk of musculoskeletal disorders (MSDs) due to repetitive physical tasks, long working hours and varying workstations. As there is no existing epidemiological overview of MSDs among garment workers, this systematic review aimed to evaluate the global evidence on prevalence of MSDs in this population.

METHODS

A systematic review of the literature was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medline, Cumulative Index to Nursing and Allied Health Literature, PubMed, Scopus and Web of Science electronic databases were searched to identify studies published in English up to November 2022. Random-effects meta-analysis was used to estimate pooled prevalence.

RESULTS

The search yielded 258 published studies, of which 14 were deemed relevant and were included in this review. The included studies reported prevalence from India (n=3), Bangladesh (n=2), Ethiopia (n=2), Thailand (n=2), Botswana (n=1), Iran (n=1), Sri Lanka (n=1), Cambodia (n=1) and Denmark (n=1) and involved 15 029 garment workers. Most of the included studies (79%) were assessed to be methodologically sound (low risk of bias). The mean age of participants ranged from 24.2 to 40 years. The prevalence of MSDs ranged from 15.5% to 92%. The pooled prevalence of MSDs from nine studies was 65.6% (95% CI 44.5% to 51.9%). Low back pain and neck pain were reported as the common MSDs in the included studies.

CONCLUSIONS

The findings highlight the considerable risk of MSDs, especially low back and neck pain, linked to repetitive tasks, extended hours and inconsistent workstations. Given the heavy toll of MSDs on this workforce, targeted interventions and ergonomic improvements are crucial to mitigate the risks and improve garment workers' well-being.

Risk factors of musculoskeletal symptoms among industrial workers in Peninsular Malaysia

Objectives. The prevalence rate of work-related musculoskeletal disorders (WMSDs) globally is notably high. There are a limited number of studies investigating WMSDs and their associated risk factors. However, there are currently no data available for WMSDs among industrial workers in Peninsular Malaysia. This study aimed to identify the prevalence of WMSDs and associated risk factors among industrial workers experiencing WMSDs through their daily working tasks. Methods. A quantitative study using a questionnaire was conducted among industrial workers from rehabilitation centres and factories in Peninsular Malaysia. The analysis of 232 participant narratives aimed to identify the correlation between job tasks and musculoskeletal pain, especially in case of repetitive and heavy handling tasks. Results. The prevalence of WMSDs among industrial workers stands at 93.1%. The results also indicate that the most affected part of the body was the lower back, with 62.1% for 7 days or more in the last year, caused by industrial workers' job tasks. The prominent risk factors associated with body parts include gender, age, working hours and most difficult tasks with MSDs, especially in the lower back. Conclusion. This survey helps us to understand whether the workers are experiencing any discomfort, pain or disability related to workplace activities.

Prevalence and associated risk factors of musculoskeletal disorders among information technology (IT) professionals: A systematic review

Musculoskeletal disorders (MSDs) are a growing concern among information technology (IT) professionals. Understanding the specific risk factors associated with MSDs among employers, occupational health practitioners, and IT professionals may reveal effective preventive measures. The aim of this study was to examine the prevalence and identify the risk factors associated with MSDs among IT professionals. A comprehensive literature search was conducted on several databases, including PubMed, Scopus, ScienceDirect, ProQuest, Online Library Wiley, Springer, Web of Science, and manual searches to identify relevant studies published between 2013 and 2023. The search strategy employed appropriate keywords related to IT professionals, musculoskeletal disorders, prevalence, and risk factors. Two reviewers independently assessed each article using PRISMA guidelines and the Joanna Briggs Institute's (JBI) Critical Appraisal Checklist for Prevalence Data. Data extraction was performed, and a narrative synthesis was conducted to summarize the findings. Our search yielded a total of 1159 records, with 13 studies finally included in this review. The selected studies were from several countries and contained a total of 4632 participants. The prevalence of MSDs was reported with a maximum rate of 89% and a minimum rate of 20%, reflecting the overall percentage of affected individuals and including data on specific body areas affected. Identified risk factors from the selected studies include work duration, experience, sex, strenuous back positions, smoking, physical inactivity, MSD history, uncomfortable workstation setting, mental stress, insufficient sleep, body posture, exercise status, alcohol consumption, prolonged sitting, workspace, job demands, overexertion, breaks during work, and excessive usage of smartphones.

Ergonomic compatibility between sewing workstation and Bangladeshi apparel workers

Prolonged sitting with awkward posture during sewing results in musculoskeletal disorders among sewing operators. This study aimed to identify the compatibility of the sewing furniture with operators' anthropometry. Therefore, 13 anthropometric measurements of 368 sewing operators were collected and compared with sewing furniture dimensions. The results showed that all anthropometric measurements other than hip breadth were larger for male participants. In addition, statistical analysis performed on the collected data showed significant variation compared to the existing dimensions of sewing machines. Results also indicated a high mismatch for different dimensions of the sewing table and chair, such as seat height, seat width, seat depth, table depth, etc. For this reason, sewing operators often experience musculoskeletal disorders. Finally, this study recommends some guidelines for designing the sewing workstation, which might act as a basis for manufacturers or importers to set provisions for sewing machines.

A systematic review of work-related health problems of factory workers in the textile and fashion industry

OBJECTIVES

The purpose of this study was to present a systematic review of the health-related problems of factory workers in the textile and fashion industry. These workers endure long sitting postures, poor workspace conditions, and long working hours to complete their overload of tasks. This situation results in several health problems that affect the productivity, mental health, and well-being of the workers.

METHODS

The relevant data (21 article publications) were obtained from the Scopus database. Analysis of the 21 articles was grouped under 3 research themes based on the critical reading of the content and abstracts: respiratory problems, musculoskeletal disorders, and psychological stressors and other health issues.

RESULTS

The findings show that factory workers are exposed to dust particles of cotton and other raw materials, fumes, and chemicals from manufacturing processes. This prolonged exposure without the use of personal protective equipment (PPE) leads to respiratory diseases like byssinosis that affect the workers' health. Additionally, working in a particular posture due to the workstation design for prolonged hours causes musculoskeletal disorders or pains. Workers also suffer from anxiety, depression, and stress from workload and pressure, hence making them unstable with reduced productivity.

CONCLUSIONS

The findings of the study reinforce the need for a safe workspace and spacious work environment, provision of PPE, training in occupational hazards, frequent health checks, and ergonomic assessment of workstations to reduce prolonged work postures. Stakeholders, employers, policymakers, and governments should collaborate to safeguard and protect the well-being and health of the workers at these factories.

Mapping the conceptual structure of ergonomics, musculoskeletal disorders, treatment and return to work in manual jobs: A systematic review

BACKGROUND

Musculoskeletal disorders constitute one of the major health problems of workers exposed to manual work throughout the world. Nevertheless, there is no study that maps its conceptual structure based on a systematic methodology.

OBJECTIVE

To identify the conceptual structure of ergonomics, MSDs, treatment and return to work in manual jobs in the last 12 years by applying a systematic co-word network analysis methodology which describes the replicability of the search filters and emphasizes the rigor that has to be followed in the creation of the network.

METHODS

The search filter was customized for each bibliographic database, and followed the PRISMA 2020 flowchart for the screening process. For the creation of the network, the titles, abstracts, and keywords were used as the unit of analysis extracting the noun phrases of the first two units. In the normalization process, the terms of the search filter were deleted and their associated terms, and standardized the similar terms. Regarding the plotting of the network, Vosviewer was used applying the network settings based on content analysis.

RESULTS

The co-word network shows three communities: Ergonomic assessment and workplace intervention tools, factors related to rehabilitation and return to work, and physical and mental overload management. For each community, there is a framework that explains the relationship within terms.

CONCLUSION

This study is aligned with the replicability, robustness, and relevance recommendations in the implementation of rigorous scientometric studies. The occupational health community is encouraged to implement scientometric studies following a rigorous methodology and working in interdisciplinary team.

Prevalence and risk factors of physical and psychological health among readymade garment workers in Bangladesh

Objective. Poor health outcomes of Bangladeshi readymade garment (RMG) workers tend to be associated with a variety of occupational factors. This study aimed to investigate the prevalence of, and risk factors associated with, the physical and psychological health outcomes of Bangladeshi RMG workers. Methods. Responses to a cross-sectional survey from a convenience sample of 411 adult Bangladeshi RMG workers (mean age = 26.24 years; SD 6.40 years; female = 80%) were analysed using bivariate and multivariate (logistic regression models) analyses. Results. More than half of the participants reported headaches (61.6%) and colds/flu (51.3%), followed by fever (37.2%), diarrhoea (32.8%), bodily pain (29.9%) and respiratory infections (20.9%). For psychological health, stress (69.1%), anxiety (66.2%) and boredom (64.5%) were most prevalent, followed by sleeplessness (51.3%), depression (48.2%) and fear (34.3%). RMG workers from the factories located in Chattogram (a peripheral region compared to Dhaka) reported poorer physical and psychological health outcomes than those working in factories in Dhaka (the capital city of Bangladesh). Overall, compared to males, female RMG workers were more likely to be vulnerable to both physical and psychological health outcomes. Conclusion. Improvement in workplace conditions and safety programmes is needed to safeguard the overall health outcomes of Bangladeshi RMG workers.

Prevalence of work-related musculoskeletal disorders and its associated factors among traditional cloth weavers in Chencha district, Gamo zone, Ethiopia, an ergonomic study

Musculoskeletal disorders at work are common in the majority of African countries. Weaving is very important in Ethiopia for the national economy and for enhancing the country's cultural values. However, the prevalence of musculoskeletal disorders in developing countries is significantly higher in common informal or small-scale enterprises such as weaving. Moreover, little is known about the prevalence and risk factors for musculoskeletal disorders in the weaving industry in Ethiopia. Therefore, the purpose of this study was to determine the prevalence of work-related musculoskeletal disorders and associated factors among traditional cloth weavers in Chencha district, Gamo zone, Ethiopia. A community-based cross-sectional study was conducted in Chencha district from November 1 to December 30, 2021, using a simple random sampling technique. A total of 420 traditional cloth weavers working in individual households were interviewed. Multivariable logistic regressions were performed on variables with p-values less than 0.025 in the bivariate analysis. Work-related musculoskeletal disorders had been reported in the previous 12 months by approximately 97 (46.9%) of respondents. Work-related musculoskeletal disorders were reported by 76.1% of weavers in the shoulder region, 64.2% in the low back, 56.3% in the neck, and 0.2% in the upper back. Working for more than 10 years (AOR = 5.05, 95%CI: 1.23, 20.77), working with prolonged sitting (AOR = 4.77, 95%CI: 1.37, 16.62), and job dissatisfaction (AOR = 2.41, 95%CI: 1.04, 5.55) were among the determinants of work-related musculoskeletal disorders. As a result, ergonomically oriented weaving workstations are required because the majority of musculoskeletal disorders are caused by poorly designed workstations.

OBJECTIVE

This study aimed to investigate the prevalence and factors associated with work-related musculoskeletal disorders among cashiers in small-scale businesses in Northwestern Ethiopia.

DESIGN

A multicentre cross-sectional study was conducted from July to September 2022. The data were collected using a validated and standardised Nordic Musculoskeletal Questionnaire. The collected data were entered into EpiData V.4.6 and analysed using Stata V.14. A multivariable logistic regression analysis was used to ascertain the significance of associations at p<0.05 and the adjusted OR (AOR) with a 95% CI.

SETTING

The study was conducted in small-scale businesses in the North Gondar Zone.

PARTICIPANTS

A total of 618 cashiers participated in this study.

OUTCOME MEASURES

The primary outcome of the study is the prevalence of work-related musculoskeletal disorders, which was measured using the Nordic Musculoskeletal Questionnaire.

RESULTS

The response rate was 97.5% (N=618). The majority (373; 60.4%) of the study participants were female. The mean (±SD) age of the participants was 30 (±8.3) years. The prevalence of work-related musculoskeletal disorders during the last 12 months was found to be 75.4% (n=466) (95% CI 71.8%, 78.8%). Marital status (married) (AOR=2.12; 95% CI 1.26, 3.56), lack of physical exercise (AOR=2.07; 95% CI 1.32, 3.23), alcohol consumption (AOR=3.55; 95% CI 2.18, 5.78) and awkward work posture (AOR=2.40; 95% CI 1.43, 4.0) were significant factors associated with work-related musculoskeletal disorders among sampled cashiers.

CONCLUSION

This study concluded that the overall prevalence of work-related musculoskeletal disorders was high among cashiers in small-scale businesses. Being married, a lack of physical exercise, alcohol consumption and awkward work posture were significant factors of work-related musculoskeletal disorders. To reduce work-related musculoskeletal disorders, it is recommended taking part in physical activity, avoiding alcohol consumption and avoiding awkward work posture.

Low back pain among professional bus drivers: a cross-sectional study from Bangladesh

BACKGROUND

Low back pain (LBP) is a common condition contributing to impaired quality of life among professional vehicle drivers. Our study aimed to assess LBP prevalence and associated factors among professional bus drivers in Bangladesh.

METHODS

A cross-sectional study was conducted among 368 professional bus drivers using a semi-structured questionnaire. A Nordic Musculoskeletal Questionnaire (NMQ) subscale was used to measure LBP. Multivariable logistic regression analysis was used to identify the factors associated with LBP.

RESULTS

In the last month, 127 (34.51%) participants reported experiencing pain or discomfort in the lower backside. Multivariable logistic regression analysis showed that age of more than 40 years (adjusted odds ratio (aOR): 2.07, 95% confidence interval (CI): 1.14 to 3.75), the income of more than 15,000 BDT per month (aOR: 1.91, 95% CI: 1.11 to 3.26), work duration more than ten years (aOR: 2.53, 95% CI: 1.12 to 5.70), working more than 15 days per month (aOR: 1.93, 95% CI: 1.02 to 3.65), working more than 10 h per day (aOR: 2.46, 95% CI: 1.05 to 5.75), poor condition of the driving seat (aOR: 1.80, 95% CI: 1.08 to 3.02), current smoking habit (aOR: 9.71, 95% CI: 1.25 to 75.15), illicit substances use (aOR: 1.97, 95% CI: 1.11 to 3.48), and four hours or less sleeping time per day (aOR: 1.83, 95% CI: 1.09 to 3.06) were positively associated with LBP.

CONCLUSION

The high burden of LBP among the participants calls for a focus on this vulnerable group's occupational health and safety, with particular emphasis on implementing standard measures.

Effectiveness of a theory-based educational intervention on work-related musculoskeletal disorders preventive behaviors among assembly-line female workers: a study protocol for a randomized controlled trial

BACKGROUND

The use of preventive behaviors of musculoskeletal disorders (MSDs) requires proper training, which leads to correct decisions regarding maintaining postures at work and performing stretching exercises. Due to very repetitive work, applying manual force, improper postures, and static contractions of proximal muscles, assembly-line female workers suffer from musculoskeletal pains. It is assumed that structured and theory-based educational intervention using a learning-by-doing (LBD) approach may increase the preventive behaviors against MSDs and reduce the consequences of these disorders.

METHODS

This randomized controlled trial (RCT) will be conducted in three phases: phase 1: validation of the compiled questionnaire, phase 2: determining the social cognitive theory (SCT) constructs that predict the preventive behaviors of MSDs in assembly-line female workers, and phase 3: designing and implementing the educational theory. The educational intervention is based on the LBD approach, and the study population includes assembly-line female workers in electronic industries of Iran, who are randomly divided into two intervention and control groups. The intervention group received the educational intervention in the workplace and the control group does not receive any intervention. The theory-based educational intervention includes evidence-based information along with pictures, fact sheets, and published literature about a good posture at work and the need to perform proper stretching exercises. The educational intervention aims to improve the knowledge, skills, self-efficacy, and intention of assembly-line female workers to adopt preventive behaviors of MSDs.

DISCUSSION

The present study will evaluate the effects of maintaining a good posture at work and performing stretching exercises on the adherence to preventive behaviors of MSDs among assembly-line female workers. The developed intervention is easily implemented and evaluated in a short period of time based on the improved score of the rapid upper limb assessment (RULA) method and the mean score of adherence to stretching exercises and can be provided by a health, safety, and environment (HSE) expert.

Musculoskeletal pain among desk-based officials of Bangladesh: Association with mental health and individual factors

Musculoskeletal (MS) pain is widely prevalent and is an important health issue for desk-based employees which has a negative impact on both personal and work life. This study aimed to determine the MS pain status and its association with mental health and other individual factors among desk-based officials of Dhaka, Bangladesh. This cross-sectional study comprised a sample of 526 desk-based officials from Dhaka, Bangladesh. Data were collected between November 2020 to March 2021. MS pain was determined by the visual analog scale (VAS) and depression and anxiety were screened by Hospital Anxiety and Depression Scale (HADS). Logistic regression analyses were employed to estimate the adjusted effect of independent factors on MS pain. The overall prevalence of MS pain was 64% among desk-based officials. The corresponding prevalence were 19% severe, 21% moderate and 24% mild MS pain. In the adjusted model, gender (AOR: 0.19, 95% CI: 0.07-0.46), BMI (AOR: 0.28, 95% CI: 0.14-0.59), monthly income (AOR: 5.17, 95% CI: 2.18-12.25), organization type (AOR: 4.3, 95% CI:1.8-10.1), floor living (AOR: 4.7, 95% CI:2.1-10.8), physical activity (AOR: 0.16, 95% CI: 0.06-0.45), and lift facility in the house (AOR: 4.11, 95% CI: 2.06-8.23) were associated with MS pain. In addition, the prevalence of anxiety and depression was 17.7% and 16.4%, respectively. Depression was identified as a significant predictor for severe MS pain (AOR: 2.44, 95%CI:1.29-4.63). This study has revealed a relatively high prevalence of MS pain and mental health problems among Bangladeshi desk-based officials. Preventive measures need to be taken from both organizational and personal sides to delimitate MS pain and mental health problems.

Occupational risks and musculoskeletal complaints among industrial workers: a cross-sectional study

Introduction

Work-related musculoskeletal disorders result from the overuse of the musculoskeletal system and insufficient time for the structures to recover. They are generally characterized by chronic pain, paresthesia, feeling of heaviness and fatigue, especially in the upper extremities, concomitantly or not, with an insidious onset.

Objectives

To characterize musculoskeletal complaints and occupational risks in workers with work-related musculoskeletal disorders.

Methods

A cross-sectional observational study of 60 participants in a Workers' Health Reference Center with clinical and imaging diagnosis of work-related musculoskeletal disorders. The instrument used contained 30 questions about individual factors, occupational risks, and musculoskeletal abnormalities. The results were analyzed descriptively, and the chi-square test was used to assess associations with a significance level at p < 0.05. Data analysis was performed using BioEstat 5®.

Results

Most participants were men (66.7%) working in the industrial sector. The most common complaint was pain (100%) in the shoulders (43.8%) and lumbar spine (22%), and the most common abnormalities were tendinopathies and intervertebral disc disorders. The following risk factors were identified: 8-hour workday (80%); repetitive gestures (86.7%); twisting (58.3%); bending (61.7%); standing (66.7%); manual work (96.7%); and 10-30 kg of weight handled (35%).

Conclusions

A large number of workers exposed to biomechanical and organizational risks report musculoskeletal pain. Employers should check working conditions and adjust them, investing in health promotion and protection actions to effectively reduce the occurrence of these disorders.

Association of ergonomics risk factors among Iranian calico crafts-men and musculoskeletal discomforts: a cross-sectional study

BACKGROUND

Work-related musculoskeletal disorders (WMSDs) have always been complaints reported by handicraft workers due to the repetitive and static nature of work. Therefore, the current study aimed to investigate the ergonomic conditions of craftsmen engaged with the calico industry.

METHOD

This cross-sectional study was done in small calico industrial workshops in Isfahan, Iran, in 2022. The sample selection method in this study was census. Using QEC (Quick Exposure Checklist) and Cornell-Musculoskeletal Discomfort Questionnaire (CMDQ), the ergonomic status of workers was evaluated. The data were analyzed using Chi-square (χ2) and Pearson's product-moment correlation test.

RESULTS

The risk level of working postures in wrist/hand, shoulder /arm, and neck were high or very high among the craftsmen. The relationships between discomfort complaints reported by the participants and the risk level of working postures were significant for neck χ² (1, N = 100) = 13.603, P_value = 0.034, left knee χ² (1, N = 100) = 12.310, P_value = 0.030 and lower left leg χ² (1, N = 100) = 11.906, P_value = 0.042. The posture risk level scores for %57.7 of the participants who self-reported the right shoulder discomfort were found to be high or very high.

CONCLUSIONS

The high risk found in most calico craftsmen may induce more serious musculoskeletal problems that require applicable interventions. The most important risk factors realized among calico craftsmen were prolonged sitting postures and repetitive tasks.

Occupational Disease and Injury in Malaysia: A Thematic Review of Literature from 2016 to 2021

Introduction

Working people are exposed to occupational hazards and are at risk of having occupational disease or injury in a rapidly industrializing country like Malaysia. This study aims to review and summarize the occupational disease and injury in Malaysia from 2016 to 2021.

Methods

This study used PubMed and Scopus databases to conduct a systematic literature search using a set of keywords. The selected records dated from 1 January 2016 to 8 September 2021 were extracted into the Mendeley Desktop and ATLAS.ti 8 software. Systematic screening was conducted by two independent researchers and finalized by the third researcher. Data were coded and grouped according to the themes. The results were presented as the table for descriptive analysis and cross-tabulation between the themes.

Results

A total of 120 records were included in this study. Under the theme of main health problems, the findings showed that mental health, infectious disease, and work-related musculoskeletal disorders are the top three problems being discussed in the literature for the working people in Malaysia. The findings also showed an increasing trend of mental health problems during pandemic COVID-19 years. In addition, hospital was the highest workplace where the occupational health problems were reported.Discussion/Conclusion. There was substantial work on the mental health problem, infectious diseases, and work-related musculoskeletal disorders as the main health problem among workers in Malaysia in the past five years. The employers must report any occupational health and injury case to the authority and prompt intervention can be initiated.

The Correlation of Frequency of Work-Related Disorders with Type of Work among Polish Employees

Musculoskeletal disorders have a significant negative impact on the quality of life of the population. These conditions, as well as other work-related disorders, generate costs associated with treatment and work absence, which makes it a growing problem in industrialized countries. Available data from studies on individual populations of workers indicate a higher incidence of certain symptoms in these groups. Due to the lack of studies on the general population, we aimed to perform the preliminary study evaluating the occurrence of pain and work-related conditions depending on the type of occupational work among Polish employees to identify further possible areas for research. Data was collected using an electronic self-administered questionnaire, which was distributed in groups bringing together various professionals. The data obtained from 379 participants have been analyzed and divided according to performed work into sedentary, forced posture, standing, physical and requiring physical activity. Our study reveals a correlation between the frequency of work-related disorders and type of work performed in the Polish population. A significant correlation between the type of occupational work and prevalence of ankle, knee and shoulder pain, as well as heavy legs or upper limb paresthesia was found. According to our findings, female employees may be more vulnerable to lower limb symptoms. A place of residence also seems to affect the prevalence of upper back pain and heavy legs. The analysis also showed a correlation between the occurrence of hip, knee and ankle pain and the level of education of the participants. Surprisingly, lower extremity paresthesia was significantly more common among participants undertaking additional physical activity, compared to non-physically active respondents.

Assessment of risk of musculoskeletal discomforts in physiotherapists treating neurological patients: A pilot study

Background

Musculoskeletal disorders (MSDs) are conditions that are caused and/or aggravated by work. The most important reason behind work-related musculoskeletal disorder is abnormal and/or stressful position of joints while working. Physiotherapists are very much prone to develop work-related musculoskeletal disorders, especially while treating neurologically challenged patients. Postural assessment is a key to identify a person at risk of developing work-related musculoskeletal disorders. Proper assessment of some of the areas like neck, spine, upper and lower extremities is the key to get risk factor analysis. REBA (Rapid Entire Body Assessment) is a tool which can be used on field to quantify areas of the body which are more likely to develop work-related musculoskeletal disorders.

Aims

Epidemiological study of work-related musculoskeletal disorders and related risk factors among automobile maintenance workers

BACKGROUND

The automotive industry is labor-intensive, and workers are involved in highly repetitive tasks, long hours, and medium to low workloads, resulting in work-related musculoskeletal disorders (WMSDs), which have become a major health concern for workers in this industry. China is a major automotive country with tens of thousands of auto repair workers, but their conditions of WMSDs have been poorly reported.

OBJECTIVE

This work aimed to analyze the current prevalence of WMSDs and their associated risk factors among automobile maintenance workers.

METHODS

A total of 539 respondents from 50 automotive repair and maintenance companies in China were selected to investigate the prevalence of WMSDs via the modified Nordic Musculoskeletal Disorders Questionnaire. Chi-square test and logistic regression models were applied to analyze their associated risk factors.

RESULTS

The total prevalence of WMSDs among 539 workers was 32.8%. The top three body parts for prevalence were the lower back (17.1%), neck (16.3%), and shoulders (14.5%). The highest prevalence of WMSDs was found in the neck (23.6%) and lower back (14.3%) for sheet metal workers and mechanics, respectively, whereas painters had the highest prevalence of WMSDs in the lower back and feet (both at 15.4%). Logistic regression analysis showed that females were at higher risk of WMSDs than males (OR 5.027, [95% CI] [1.278-19.772], p < 0.05). Workers subjected to uncomfortable positions were at increased risk of WMSDs (OR 1.79, [95% CI] [1.333-2.410], p < 0.01).

CONCLUSION

The prevalence of WMSDs is high among automotive maintenance workers, with the highest prevalence in the lower back (17.1%). Uncomfortable working postures and frequent repetitive movements with lower limbs and ankles at work may be important risk factors.

Work-family conflict, financial issues and their association with self-reported health complaints among ready-made garment workers in Bangladesh: a cross-sectional study

OBJECTIVES

This study aims to quantify the degree of work-family conflict (WFC) and financial issues among ready-made garment (RMG) workers in Bangladesh and to investigate their potential associations with self-reported health outcomes.

METHODS

We conducted a cross-sectional survey among 1118 RMG workers in labor colonies in Dhaka, Bangladesh, in February and March 2021. Descriptive analyses were performed to characterize WFC (i.e., family life disturbing the job or facing problems in family due to the job) and financial issues (i.e., savings, debt, financial obligations, financial support). We ran multivariable Poisson regression models to examine possible associations between WFC and financial issues and workers' health (self-reported general health and 10 specific health complaints).

RESULTS

We found low levels of WFC, low levels of savings, moderate levels of debt, and high levels of financial obligations: virtually all workers agreed they had to keep their job to financially support their spouse, children or other relatives. Only about a third of workers expected they would be able to receive financial support in case of a job loss. Work-family conflict was positively associated with poor health but not consistently with specific symptoms. Financial support was negatively associated, whereas being indebted was weakly positively associated with poor health.

CONCLUSIONS

Our findings suggest low levels of WFC among RMG workers but high levels of financial obligations. Work-family conflict was positively associated with poor health, but not consistently with specific symptoms. Being indebted was weakly positively associated with poor health. Future prospective studies are needed to confirm these findings.

Fore-Warned Is Fore-Armed: Effect of Musculoskeletal Disorders on Sickness Absenteeism

Background Musculoskeletal disorders (MSDs) are one of the most common occupational diseases. MSDs cause an economic burden as they lead to disability, absenteeism, and reduced productivity. Although many risk factors have been associated with the incidence of MSDs, little is known about the predictive factors for the length of MSD-related absenteeism. The study aimed to estimate the prevalence of MSDs among garment factory workers, determine the predictive factors for length of sickness absence, and evaluate the association of these factors with time. Methodology This prospective, observational, community-based study was conducted among garment factory workers. A total of 430 participants were included in the study by multistage sampling to assess the prevalence and factors causing MSDs, followed by a one-year follow-up to analyze the MSD-associated predictors for sickness absence. The data were analyzed using SPSS version 22 (IBM Corp., Armonk, NY, USA). The chi-square test and logistic regression were used to test significance, and Cox regression was used to determine the predictive factors for sickness absence. Results The mean age of the participants was 29.36 years. The 12-month prevalence showed that the most affected region was the lower back (70%), followed by the upper back (40%), with some workers experiencing both. There was a significant relation between MSDs and higher age, low work experience, being overweight, and long work hours (p < 0.05). According to the multivariate analysis, the perceived pain (hazards ratio (HR) = 1.14), perceived physical workload (HR = 1.14), and visiting a specialist 12 months prior to the current absence (HR = 1.68) were significantly associated with a longer sickness absence. Conclusions The lower and upper back were most commonly affected. The predictors for absence revealed that physical work overload and pain perception had a predominant role in the duration of absence. Hence, an ergonomically acceptable workplace with considerate rest periods will help enhance productivity.

Social stressors and social resources at work and their association with self-reported health complaints among ready-made garment workers in Bangladesh: a cross-sectional study

BACKGROUND

Bangladesh is one of the world's largest garment exporters. Physical working conditions of garment workers are precarious and known to largely affect their health. Research on garment workers' psychosocial working conditions, however, is scarce. We aimed to quantify psychosocial working conditions of garment workers and possible associations with workers' health.

METHODS

We conducted a cross-sectional survey among 1,118 ready-made garment (RMG) workers in labor colonies in Dhaka, Bangladesh, in February 2021. Descriptive analyses were performed to characterize social stressors (e.g., being bullied at work, poor leadership) and social resources at work (e.g., receiving support at work, vertical trust between management and employees, beneficial leadership) and workers' health (self-reported overall health and 10 specific health complaints). To examine links of social stressors and social resources with self-reported health outcomes we ran multivariable Poisson regression models yielding prevalence ratios (PR) and 95% confidence intervals (CI).

RESULTS

We found low to moderate levels of workplace bullying and high levels of poor leadership (i.e., supervisors not caring about workers' problems). We also found high levels of social support, vertical trust and beneficial leadership (i.e., supervisors taking decisions free of bias). Garment workers frequently suffered from health complaints, first and foremost headache (68.3%), cold (55.3%), and back pain (50.7%). Health outcomes were poorer among workers who reported to be bullied at work versus not bullied (e.g., PR 1.55 [95% CI 1.32-1.92] for poor self-reported health when bullied by colleagues) and health was better among those reporting to feel supported versus unsupported (e.g., PR 0.61 [0.52-0.71] for poor self-reported health when supported by supervisor). Perceived vertical trust between workers and management was weakly associated with better health. Leadership behavior did not display a consistent pattern.

CONCLUSIONS

Our findings suggest that working conditions of RMG workers are rather good (e.g., characterized by low levels of bullying and high levels of support, vertical trust and beneficial leadership). The majority of workers reported good or very good health, although health complaints were frequently mentioned, first and foremost headache, cold, and back pain. Associations between psychosocial working conditions and health indicate worse working conditions being associated with poorer health.

Prevalence of symptoms of work-related musculoskeletal disorders and their associated factors: A cross-sectional survey of sewing machine operators in Sindh, Pakistan

BACKGROUND: The nature of the work of sewing machine operators predisposes them to a wide variety of symptoms of musculoskeletal disorders and obesity. However, there is a paucity of studies on the prevalence and associated factors for symptoms of work-related musculoskeletal disorders (WMSDs) among this occupational group. OBJECTIVES: This study aimed to determine the prevalence of symptoms of WMSDs and their association with personal and occupational factors and body mass index (BMI) among sewing machine operators of Sindh province in Pakistan. METHODS: This cross-sectional study was conducted on male sewing machine operators in two major cities (i.e., Hyderabad and Nawabshah) of Sindh province in Pakistan. Obesity was determined through the BMI cutoff values for Asians. Standardized Nordic Musculoskeletal Questionnaire and Numeric Rating Scale were used. Data analysis was performed using SPSS v20. RESULTS: Of the 200 participants, 91% participants had symptoms of WMSDs in the past 12 months. Most (41.5%) participants reported pain and discomfort during the last 12 months in the lower back region. Symptoms of WMSDs in the lower back region had a significant positive association with working days/week (r = .196** p = .005). Symptoms of WMSDs in the ankle/feet region had a significant positive association with age (r = .246** p = .001) and work experience (r = .276** p = .001). CONCLUSIONS: Prevalence of symptoms work-related musculoskeletal disorders is high among sewing machine operators of Sindh province in Pakistan, with significant associations between personal and occupational factors.

Workplace-based rehabilitation with garment workers: A multiple case study

BACKGROUND: Garment workers are at risk of developing work-related upper limb disorders (WRULD) due to the highly repetitive nature of their work. Workplace-based rehabilitation (WBR) facilitates improvement in work performance by providing intervention at the worker’s place of work. OBJECTIVE: This study aims to determine the documented outcomes of workplace-based occupational therapy rehabilitation of garment workers with upper limb conditions. METHODS: A multiple case study design was used through a retrospective record review. All garment workers with upper limb conditions who were treated at a student occupational therapy practice in Cape Town, South Africa, with pre- and post-intervention outcome assessment, were included in the study (n = 7). Data were extracted from occupational therapy and medical files. RESULTS: 70% of the cases (n = 5) improved after WBR while 30% of cases showed no improvement or deterioration. Participants received 3– 5 individual WBR sessions of approximately 30 minutes each, over a period of 4 to 6 weeks. Interventions included workstation adaptations, job rotation, psychoeducation, work task modification, assistive technology and exercise programmes. Outcome measures most commonly used were the RULA, DASH, Boston Carpal Tunnel Questionnaire and pain intensity using the VAS. CONCLUSION: Workplace-based occupational therapy can be effective at improving upper limb function, pain and ergonomic risk amongst garment workers with upper limb conditions.

Development of an educational protocol for ergonomic risk assessment of working postures to enhance the competence of occupational health nurses

AIM

To develop a protocol and provide a valid, evidence-based procedure for identifying the ergonomic risk of working postures by occupational health nurses.

BACKGROUND

Although ergonomic risk assessment tools have been used for the early detection of risky working postures, their operational procedures and validations do not target the competence of occupational nursing personnel.

DESIGN

This study developed and validated an educational protocol, comprised of 13 procedures in five stages. First, the number of work tasks in the workplace is determined. Second, the working postures are confirmed. Third, the raters are trained to use the assessment tools. Fourth, high-risk postures are identified and categorized. Fifth, the inter-rater reliability of the tool is reported. The content of the protocol is validated by experts, with a validity value of 0.87.

DATA SOURCES

The protocol was created through review of literature published from 1991 to 2021, protocol development (between 2018 to 2020) and expert validation (2020).

CONCLUSION

The protocol can be applied to educate occupational health nurses and increase their competence in detecting workers' ergonomic risks. It can be used as a reference in occupational health nursing education to evaluate work tasks and detect risky postures.

Prevalence and associated factors of lower extremity musculoskeletal disorders among manufacturing workers: a cross-sectional study in China

OBJECTIVE

To survey the prevalence of lower extremity musculoskeletal disorders (MSDs) among Chinese manufacturing workers, and to identify the associated factors.

DESIGN

Observational study with cross-sectional design.

SETTING

A self-administered questionnaire survey was conducted in four manufacturing factories in China.

PARTICIPANTS

7908 manufacturing workers were included in this study after excluding non-conforming personnel.

OUTCOME MEASURES

Individual and work-related information, and MSDs in the whole leg and knee region were measured by the anonymous self-administered questionnaire. Individual and work-related factors associated with MSDs and their effects were identified through multivariate logistic regression.

RESULTS

Of all respondents, 3241 (41.0%) reported having had lower extremity MSDs in the recent 12 months, and for the knees, ankles/feet and hips/thighs were 29.5%, 23.9% and 16.7%, respectively. After confounder-adjusted single-factor analysis, 22 variables (of 24) were significantly related to the disorders. Factors like always kneeling/squatting for long periods, always standing for long periods and often lifting in an uncomfortable position were shown to have higher risks, with ORs of 2.77 (95% CI: 2.33 to 3.30), 2.30 (1.96 to 2.69) and 2.25 (2.04 to 2.47). Comparable results were found on knee disorders. The final model included 15 variables of demography, biomechanics and work organisation. The following factors showed increased risks of lower extremity MSDs: being female, being older, longer working years, higher body mass index (BMI), keeping the same posture for a long time, awkward position, shift work and monotonous work. Whereas having enough breaks reduced the risk.

CONCLUSION

The prevalence of lower extremity MSDs among Chinese manufacturing workers is high. The most commonly affected body regions were the knees and ankles/feet. Multiple factors were found associated with lower extremity MSDs including age, BMI, work experience, work organisations, physical ergonomics exposures, etc.

Buyer–Supplier Role in Improving Ergonomics in Garment Supplier Factories: Empirical Evidence from the Garment Industry of Bangladesh

Ergonomics is a key concern of garment suppliers to improve their workers’ well-being and efficiency. However, suppliers’ isolated initiatives are not sufficient to improve ergonomics conditions. Thus, buyers’ cooperation and collaboration with suppliers are necessary to make the ergonomic initiatives successful and sustainable. The purpose of this study is to investigate the impact of buyer-assisted ergonomics intervention on suppliers’ performance and the role of buyers’ assistance and suppliers’ initiatives for improving ergonomics conditions in garment supplier factories. Following a qualitative research approach and multiple embedded case study method, this study intervened in supplier factories and collected qualitative and quantitative data from one Danish buyer and their four key suppliers on ergonomics and the role of buyers and suppliers in improving ergonomics conditions. Collected data were analysed by employing both quantitative and qualitative data analysis techniques. This study demonstrates that buyer-assisted ergonomics intervention on the shop floor can improve ergonomics conditions in garment supplier factories. This study also shows that improving ergonomics in supplier factories need joint efforts of buyers and suppliers. The findings of this study will enrich the literature on ergonomics, sustainability, and buyer–supplier relationships by demonstrating how garment suppliers in developing countries can improve ergonomics to meet the expectations of lead buyers and their workers. This is a unique research attempt to understand ergonomics from a buyer–supplier relationship perspective and its impact on the social sustainability of garment suppliers.

A Directional Vibrotactile Feedback Interface for Ergonomic Postural Adjustment

The objective of this paper is to develop and evaluate a directional vibrotactile feedback interface as a guidance tool for postural adjustments during work. In contrast to the existing active and wearable systems such as exoskeletons, we aim to create a lightweight and intuitive interface, capable of guiding its wearers towards more ergonomic and healthy working conditions. To achieve this, a vibrotactile device called ErgoTac is employed to develop three different feedback modalities that are able to provide a directional guidance at the body segments towards a desired pose. In addition, an evaluation is made to find the most suitable, comfortable, and intuitive feedback modality for the user. Therefore, these modalities are first compared experimentally on fifteen subjects wearing eight ErgoTac devices to achieve targeted arm and torso configurations. The most effective directional feedback modality is then evaluated on five subjects in a set of experiments in which an ergonomic optimisation module provides the optimised body posture while performing heavy lifting or forceful exertion tasks. The results yield strong evidence on the usefulness and the intuitiveness of one of the developed modalities in providing guidance towards ergonomic working conditions, by minimising the effect of an external load on body joints. We believe that the integration of such low-cost devices in workplaces can help address the well-known and complex problem of work-related musculoskeletal disorders.

The Relationship of Grip and Pinch Strength to Musculoskeletal Disorders in Female Carpet Weavers in Southeastern Iran, 2019

Background:

The repetitive and prolonged exertion of grip and pinch strength are current among carpet weaver tasks. The three objectives of this study were (1) to investigate the relationship between symptoms of musculoskeletal disorders and grip and pinch strength of carpet weavers in carpet weaving workshops in Kerman province, (2) to compare the grip and pinch strength of carpet weavers with normal values, and (3) to identify the relationship between hand postures of carpet weavers during work and force exertion.

Methods:

In this cross-sectional study, grip strength and key, tip and palmar pinch strengths of 101 female carpet weavers aged 20 to 71 years were measured in Kerman province, in 2018. Nordic Musculoskeletal Questionnaire (Extended version) was also used to evaluate musculoskeletal disorders.

Results:

Bivariate and multivariate linear regression analyses showed that participants who suffered from musculoskeletal disorders had lower grip and pinch strength than others and this decrease was statistically significant in upper back, wrists/hands, and knees. Moreover, there was a significant difference between grip and three types of pinch strength of carpet weavers and normal values. Furthermore, for both hands, the grip strength in the position recommended by American Society of Hand Therapists was significantly greater than that in the normal position carpet weavers usually adopt.

Conclusion:

Based on the results, the high prevalence of musculoskeletal disorders has led to a significant decrease in the grip and pinch strength of carpet weavers. Therefore, it is necessary to undertake ergonomic interventions in designing the carpet weaving workstation.

Prediction of work productivity outcomes by identifying critical risk factors among garment industry workers

Work productivity is one of the most important economic measures in the manufacturing industry. However, the physical, psychosocial and individual risk factors of an industrial work environment affect workers' physical or mental health, resulting in work productivity loss, absenteeism and presenteeism. Therefore, this study aims to identify the most critical risk factors and develop statistical models for predicting work productivity loss, absenteeism and presenteeism of garment industry workers. A sample of 224 sewing machine operators was taken for data collection through observation and self-reported studies. The results indicated that the average work productivity loss, absenteeism and presenteeism was 38.21, 2.35 and 37.23%, respectively. Finally, the statistical models of work productivity loss, absenteeism and presenteeism was developed using multiple linear regression with precision of 69.9, 53.7 and 84.0%, respectively. Hence, this study will help garment industries to improve their work productivity by taking initiatives based on the developed models.

Prevalence and risk factors for MSDs in vegetable greenhouse farmers: a cross-sectional survey from Shandong rural area, China

Purpose:

The aim of the research is a cross sectional survey on the prevalence of symptoms related to MSDs in vegetable greenhouse farmers from Shandong rural area and on the risk factors that may influence it.

Methods:

This cross-sectional survey was selected 249 farmers working in vegetable greenhouse from different districts of Shandong Province, China. The Questionnaire and the Rapid Upper Limb Assessment (RULA) technique were used to identify ergonomic risks. χ² analysis was used to find the relationship between MSDs and various factors. Also, logistic regression methodology was applied to get the most influencing factor for MSDs.

Results:

The prevalence of MSDs in farmers working in vegetable greenhouse is 87.5%, and the top 3 prevalent areas of MSDs in various parts of the body are: lower back (47.4%), neck (33.3%), and shoulder (31.7%). The results of Logistic regression analysis showed that age, years working in vegetable greenhouses, keeping their backs in the same position for a long time, and working hours greater than 10 hours per day were the risk factors for MSDs in the farmers. The outcome of the RULA grand score had been found to be higher than 5 in the overwhelming majority of the farmers.

Conclusions:

All findings infer that each task of greenhouse vegetable growing inflicts different levels of disorder in a farmers’ musculoskeletal structure. Interventions should be increased and reduce the bad ergonomic load level as soon as possible, provided to reduce the impact of such disorders.

Evaluation and analysis of new design traditional handloom performance in reducing work musculoskeletal disorders among Sarong Samarinda female weavers: A quasi-experimental study

Background:

Work musculoskeletal disorder (WMSDs) are occupational health problems whose prevalence is still high in various countries. Ergonomic interventions are the most successful approach to reducing WMSDs. This study evaluated the effect of redesign traditional handloom on the work posture and musculoskeletal disorders of Samarinda Sarong traditional weavers.

Methods:

The quasi-experiment has been carried out on 40 traditional weavers from February to September 2019 in Samarinda, Indonesia. The weaver using the new design handloom then evaluated its impact on work posture and WMSDs in the first 3 months and the second 3 months. Work posture was assessed using Rapid Upper Limb Assessment (RULA). WMSDs were assessed using a Nordic Body Map questionnaire. Data were analyzed using Friedman and Dunn's test.

Results:

The RULA score decreased from 7 to 3 and 2, while the WMSD risk at “very high” level decreased from 12.5% to 7.5% and 2.5% and the WMSD at “high” risk level decreased from 87.5% to 10.0% and 5.0% following the introducing of the new design traditional handloom at 3 and 6 months, respectively.

Conclusions:

The new design of the traditional handloom on Sarong Samarinda female weavers has succeeded in improving work posture and reducing WMSDs.

Landscaping Work: Work-related Musculoskeletal Problems and Ergonomic Risk Factors

Background

Work-related musculoskeletal disorders (WRMSDs) are considered one of the foremost reason of disability globally with significant economic impact due to loss of productivity. Landscaping work is considered a high-risk industry in the service sector. Landscape workers are susceptible to WRMSDs as they are exposed to high physical demands at work, and exert significant physical effort to complete daily repetitive tasks during long working hours. The aim of this study was to determine the prevalence of WRMSDs and to identify the ergonomic risk factors among landscape workers in a university setting.

Methods

This was a cross-sectional study conducted among landscape workers at a public university in Kota Kinabalu, Sabah. Interviews were conducted due to low literacy of the participants, using structured questionnaires which consist of personal characteristics, work descriptions, ergonomic risk factors, as well as self-reported WRMSD symptoms using NORDIC questionnaire. Ergonomic risk assessment (ERA) using rapid entire body assessment (REBA) was then conducted.

Results

Fifty-five of 60 landscape workers agreed to participate (92% response rate). The overall prevalence of WRMSDs among landscape workers was 85.5%. The highest prevalence involving the shoulder (65.5%), followed by neck (23.6%), wrist/hand (23.6%), and lower back (20.0%) regions based on their self-reported WRMSD symptoms over the past 12 months. Awkward posture was the risk factor identified through ergonomic risk assessment (ERA) conducted by ERA trained personnel. None of the working postures during assessment was noted to be appropriate. Although no significant difference was associated with self-reported WRMSDs, majority of the landscape workers (71%) were classified as medium ergonomic risk group using REBA, with the remaining 29% considered to be high ergonomic risk group.

Conclusion

Improvement in awareness campaigns, modification of working tools, and enhanced administrative approaches are among the control and prevention measures recommended to delay or prevent the occurrence of WRMSDs.

Registered health problems and demographic profile of integrated textile factory workers in Ethiopia: a cross-sectional study

BACKGROUND

Textile and garment factories are growing in low and middle-income countries as worldwide demand for inexpensive clothing increases each year. These integrated textile and garment production factories are often built-in areas with few workplaces and environmental regulations, and employees can be regularly exposed to workplace hazards with little regulatory oversight. Consequently, workers' health may be significantly affected due to long term exposure to hazards. This study describes registered health problems and their association to work-related and personal factors among workers in integrated textile factories in Ethiopia.

METHODS

Institution-based cross-sectional study design was employed for this analysis. A one-year recording of worker's clinical diagnoses (between March 2016 and February 2017) was gathered from the factory clinics of three integrated textile factories. Clinical diagnosis data was obtained as factory workers visited the clinics if feeling unwell. Sociodemographic characteristics and work-related information were obtained from the factory's human resource departments. The sociodemographic and clinical diagnosis statuses of 7992 workers were analyzed. The association between the registered diagnoses and workplace factors (work in textile production, garment production and support process) and personal factors (age, sex and educational status) were studied using logistic regression analysis.

RESULTS

The average employee age and years of service were 40 years and 11 years respectively. 60% of workers were females, comprising of 4778 women. 66% of all workers (5276) had 27,320 clinical diagnoses. In total, this caused 16,993 absent working days due to sick leave. Respiratory diseases (34%) and musculoskeletal disorders (29%) were the most prevalent diagnoses, while bodily injuries were the cause of most work absences. Work department, sex and educational status are variables that were most significantly associated with higher prevalence of disease groups.

CONCLUSIONS

About two-thirds of the integrated textile factory workers were diagnosed with different types of disease. The textile and garment production department workers were affected at a greater rate than the support process workers, indicating that some diseases may be related to workplace exposure. Further study should investigate rare chronic diseases such as cancer, heart diseases, renal diseases and diabetes.

Implementation of Kinetic and Kinematic Variables in Ergonomic Risk Assessment Using Motion Capture Simulation: A Review

Work-related musculoskeletal disorders (WMSDs) are among the most common disorders in any work sector and industry. Ergonomic risk assessment can reduce the risk of WMSDs. Motion capture that can provide accurate and real-time quantitative data has been widely used as a tool for ergonomic risk assessment. However, most ergonomic risk assessments that use motion capture still depend on the traditional ergonomic risk assessment method, focusing on qualitative data. Therefore, this article aims to provide a view on the ergonomic risk assessment and apply current motion capture technology to understand classical mechanics of physics that include velocity, acceleration, force, and momentum in ergonomic risk assessment. This review suggests that using motion capture technologies with kinetic and kinematic variables, such as velocity, acceleration, and force, can help avoid inconsistency and develop more reliable results in ergonomic risk assessment. Most studies related to the physical measurement conducted with motion capture prefer to use non-optical motion capture because it is a low-cost system and simple experimental setup. However, the present review reveals that optical motion capture can provide more accurate data.

Low back pain and associated risk factors among medical students in Bangladesh: a cross-sectional study

Background: Low back pain (LBP) is one of the leading causes of disability worldwide. Different studies showed the high prevalence of LBP among medical students. However, no study has been conducted on Bangladeshi medical students to estimate the prevalence of LBP. This study evaluated the prevalence, characteristics, and associated risk factors of LBP among medical students in Bangladesh. Methods: A cross-sectional study was conducted from October to December 2020 among randomly selected 270 medical students and medical interns in Faridpur Medical College, Bangladesh, using an online questionnaire. In data analysis, chi-square test and binary logistic regression were performed, and a p-value of < 0.05 was regarded as statistically significant. Results: A total of 207 participants responded fully to the survey, and were included in the analysis. The mean age of the participants was 22.36 ± 1.915 years. The point, 6-month, and 12-month prevalence of LBP was 25.6%, 46.9%, and 63.3%, respectively. In most participants, LBP was localized (53.2%), recurrent (64.9%), undiagnosed (70.8%), affected for a short period (55%), and relieved without receiving any treatment (60.4%). Participants who had a significantly higher 12-month prevalence of LBP included females (72.2% vs 52.2%), with BMI >25 kg/m 2 (73.2% vs 56.7%), those who performed physical activity at low to moderate frequency (72.4% vs 29.5%), those who spent > 6 hours/day by sitting (71.3% vs 45.3%), and those who did not have enough rest time (92.7% vs 56%). Ergonomic features of chairs, such as having back support, adjustable back support, and adjustable sitting surface, significantly (p < 0.05) influenced the outcomes. Conclusion: The prevalence of LBP among medical students in Bangladesh was high, and most of the risk factors associated with the high prevalence of LBP were modifiable. Hence, LBP can be prevented by implementing preventive strategies and providing ergonomic training and physical activity facilities.

Participants who had a significantly higher 12-month prevalence of LBP included females (72.2% vs 52.2%), with BMI >25 kg/m 2 (73.2% vs 56.7%), those who performed physical activity at low to moderate frequency (72.4% vs 29.5%), those who spent > 6 hours/day by sitting (71.3% vs 45.3%), and those who did not have enough rest time (92.7% vs 56%). Ergonomic features of chairs, such as having back support, adjustable back support, and adjustable sitting surface, significantly (p < 0.05) influenced the outcomes. Conclusion: The prevalence of LBP among medical students in Bangladesh was high, and most of the risk factors associated with the high prevalence of LBP were modifiable. Hence, LBP can be prevented by implementing preventive strategies and providing ergonomic training and physical activity facilities.

Assessing the Work Activities Related to Musculoskeletal Disorder among Critical Care Nurses

Nurses are physically exhausted with an incidence of work-related musculoskeletal disorders (MSDs), especially those working in critical care units that require exhaustive physical efforts to fulfill patients' needs. The current study aims to assess work activities related to the occurrence of MSDs in nurses working in critical care units. A descriptive cross-sectional study was conducted on a sample of 100 nurses of critical care units, and the data were collected via a survey questionnaire. The study was conducted at King Fahad University Hospital for three months from February to April 2019. The study findings revealed that work activities related to MSD were associated with sociodemographic data, age, and neck pain (rho = 0.063) (p=0.03) and lower back pain (rho = 0.89) (p=0.03); education level with hip/thigh pain (rho = 0.64) (p=0.03); standing time with shoulder pain (rho = 0.66) (p=0.04), wrist/hand pain (rho = -0.75) (p=0.05), hip/thigh pain (rho = -0.78) (p=0.004), and knee pain (rho = -0.77) (p=0.005). An increased prevalence of MSDs with lower back pain (92%) and upper back pain (56%) was estimated among the nurses, and a negative impact of work-related MSDs on occupational health and daily life activities of the nurses was also observed. The study concluded that the occurrence of MSDs is significantly associated with sociodemographic data: age, BMI experience level, and educational level of nurses of critical care units.

Musculoskeletal Disorders Associated With Quality of Life and Body Composition in Urban and Rural Public School Teachers

Introduction: Teachers have been reported to be a labor group with high rates of musculoskeletal disorders (MSDs), stress, and strong deterioration of quality of life (QoL). However, little information exists about the association between MSD, QoL, and body composition in rural and urban teachers.

Objective: The aim was to study the association of MSD with QoL perception and body composition of urban and rural teachers.

Participants and Methods: Participants are comprised a representative sample of urban and rural public schoolteachers from the Valparaiso Region, Chile. MSDs were evaluated with the Standardized Nordic Questionnaire for Musculoskeletal Symptoms validated for the Chilean population. QoL perception was evaluated with the 36-Item Short-Form Survey (SF-36). Body composition was measured via bioimpedance. A logistic regression model was used to evaluate the association between MSD, QoL, and body composition, adjusted for age and gender.

Results: A total of 88.9% (urban 90%; rural 87%) of teachers felt pain in some body area, 71.2% of them with limitations; 39% of teachers presented body fat obesity, with the highest rate in rural women. The body area with the greatest MSD prevalence was the neck and shoulders (68.6%). Significant differences were observed between teachers with >p75 of MSD (over six pain regions) and those with ≤p75 (six or fewer painful regions; p < 0.05) on six QoL scales and on physical health components (PCSs) and mental health (MCS) in urban teachers. However, rural teachers presented no differences. The association between teachers with >p75 MSD and low QoL perception was significant (p < 0.05) in PCS and MCS. Furthermore, the regression model presents a significant association between rural areas and low PCS perception.

Conclusions: Urban and rural teachers present high rates of MSD and obesity. Teachers with higher rates of MSD have their mental and physical QoL affected, making workplace intervention in MSD necessary to prevent teacher health deterioration.

Workplace musculoskeletal problems in occupational therapy students

Background

Workplace musculoskeletal disorders are the leading cause of morbidity and disability in the Australian workforce. Over one in five occupational therapists report workplace musculoskeletal disorders, with almost half reporting workplace musculoskeletal symptoms. In other health professions, students and novice clinicians (≤5 years practice) experience greater risk but little is known about occupational therapy students.

Methods

In this cross-sectional study, a survey including the self-reported Standardised Nordic Musculoskeletal Questionnaire was administered to occupational therapy students post work-based training. Musculoskeletal problems were defined as aches, pains, numbness or discomfort. Questions explored body sites affected, prevalence, impact on activity, need for medical assistance, demographic and workplace information. Prevalence was reported using descriptive statistics. Factors associated with workplace musculoskeletal problems over the previous 12 months and last 7 days were examined using logistic regression modelling.

Results

Response rate was 53% (n = 211/397). One-third of respondents (33.6%, n = 71/211) reported a workplace musculoskeletal problem over 12 months. Nearly half (47.9%, n = 34/71) of these students reported a problem over the last 7 days. Neck was the most commonly affected area reported for musculoskeletal problems over the past 12 months (24.2%, n = 51/211) and shoulder areas affected over the past 7 days (10.9%, n = 23/211). Musculoskeletal problems preventing daily activities were reported most commonly from lower back problems over 12 months (23.9%, n = 17/71) and for shoulder problems over the last 7 days (21.9%, n = 7/32). Shoulders and knees were the most common body areas requiring medical attention. Previous musculoskeletal problems and female gender were associated with reported problems over 12 months and last 7 days (p < 0.05). Non-standard joint mobility (OR = 3.82, p = 0.002) and working in psychosocially focused caseloads (including mental health or case management) (OR = 3.04, p = 0.044) were also associated with reporting musculoskeletal problems over the last 7 days.

Conclusions

One in three occupational therapy students already experience workplace musculoskeletal problems impacting daily activities and requiring medical assistance prior to graduation. High prevalence of musculoskeletal problems in this study calls for educators and researchers to find sustainable strategies to address these problems, with particular consideration to the impact of previous disorders and working in psychosocially focused caseloads on musculoskeletal health.

Workplace stress and associated factors among vehicle repair workers in Hawassa City, Southern Ethiopia

INTRODUCTION

Workplace stress is a public health problem worldwide. Studies focusing on work-related stress among vehicle repair workers are scarce in African countries. The current study aimed to determine the prevalence of self-reported workplace stress and associated factors among vehicle repair workers in Hawassa City, South Ethiopia.

METHODS AND FINDINGS

A cross-sectional study design was employed among 347 vehicle repair workers from January 25 to February 22, 2019. Questionnaires were administered using interviews. Additional tools were used for weight and height measurements. The main findings were analyzed using descriptive statistics, bivariable, and multivariable logistic regression. The strength of association of variables was presented by odds ratio along with its 95% CI. The statistical assessments were considered significant at p<0.05. A total of 344 workers participated in the study. The prevalence of workplace stress among participants was 41.6% with 95% CI: (36.3-47.1). Factors associated with workplace stress were more than 10 years of work experience [AOR: 2.40; 95% CI (1.29-4.50)], work-related musculoskeletal disorder [AOR: 3.39; 95% CI (1.99-5.78)], squatting and lying work posture [AOR: 4.63; 95% CI (1.61-13.3)] and servicing large vehicles [AOR: 1.96; 95% CI (1.14-3.38)].

CONCLUSION AND RECOMMENDATIONS

This study showed that the overall prevalence of work-related stress was substantially high. The independently associated factors were workers' service years, symptoms of body pain, and the work environment. Preventive measures need to be implemented in vehicle repair workshops by focusing on work environment improvements.

Factors Associated with Musculoskeletal Disorders Among Female Readymade Garment Workers in Bangladesh: A Comparative Study Between OSH Compliant and Non-Compliant Factories

Purpose

Musculoskeletal Disorders (MSDs) are one of the most common occupational diseases responsible for work restriction and absenteeism. The purpose of the study was to compare the prevalence of MSDs between ready-made garment (RMG) factories that are compliant versus non-compliant with International Labor Organization (ILO) based Occupational Safety and Health (OSH) standards, and to identify other factors associated with a higher prevalence of MSDs.

Methods

A multicenter cross-sectional study was conducted among 410 randomly selected female workers (age: >18 years; ≥1 year of work experience) from 12 randomly selected RMG factories in the Dhaka district of Bangladesh from February to December 2019. Factories were stratified as OSH compliant or non-compliant. Data were collected using a structured questionnaire consist of socio-demographic, work-related factors, and Nordic Musculoskeletal Questionnaire (NMQ) for MSD assessment. Robust Poisson regression was used to investigate the association of MSDs with OSH compliance, socio-demographic and other work-related factors.

Results

Respondents’ mean age was 26.9 ± 5.9 years. A total of 235 (57%) of the workers reported musculoskeletal pain in at least one body part during the last month. Among the nine reported MSDs, the prevalence of lower back pain was highest (41%) followed by pain in the knees (33%). Multivariable analysis showed lower prevalence of any MSD among workers in OSH compliant factories [aPR = 0.43, 95% CI: 0.31–0.58], and workers with regular working hours (8 hrs/day) [aPR = 0.79, 95% CI: 0.62–1.00]. The risk of developing any MSD was significantly higher for age group 25–30 years [aPR = 1.16, 95% CI: 1.01–1.33] and age group ≥31 years [aPR = 1.21, 95% CI: 1.04–1.1.39].

Conclusion

The study found a high burden of musculoskeletal disorders among female RMG workers, especially those in non-OSH compliant factories that work long hours. Enforcement of minimum ILO-based OSH standards and introduction of low-cost interventions to improve working conditions in non-compliant factories would help sustain the pace of development in this sector in Bangladesh, and ensure the health of the women who work there.

Prevalence of work related musculoskeletal disorders in Italian workers: is there an underestimation of the related occupational risk factors?

Background

Work-related musculoskeletal disorders (WMSDs) represent an important socio-economic burden. The current risk assessment and management involved in the ethiopathogenesis of WMSDs is based on observational tools and checklists, which have some limitations in terms of accuracy and reliability. The aim of this study was to assess WMSD prevalence and identify possible correlations with several socio-demographic and work-related variables in a large cohort representative of Italian workers in order to improve our understanding of the WMSD phenomenon.

Methods

This study includes data from INSuLa, a cross-sectional nationally representative survey of health and safety at work, developed by the Italian Workers’ Compensation Authority. A total of 8000 Italian workers were included. Multivariate logistic regression analyses were performed to evaluate the association of independent variables, such as workers’ perceptions of exposure to biomechanical/ergonomic and video display unit (VDU) risks (Risk Perceived) and the actual risk exposure (Risk Detected) on Back, Lower and Upper limb pain. Socio-demographic, occupational and other health-related variables were included to investigate possible association with musculoskeletal disorders.

Results

Workers perceiving a significant exposure to biomechanical/ergonomic and VDU risks but not included in a health surveillance program for them (Risk Perceived/No Risk Detected) have had significantly higher odds of reporting musculoskeletal disorders. Regarding the biomechanical/ergonomic risk these workers are in the 19–24 age range (39.9%), transportation, warehousing/information and communication sectors (38.9%) and are employed in companies with more than 250 workers (35.8%). Regarding VDU risk, workers are in the 45–54 age range (24.5%), professional, financial and business services (38.0%) and come from companies with more than 250 employees (25.6%).

Conclusions

Within the occupational safety and health management systems an appropriate assessment of occupational risk factors correlated to musculoskeletal disorders (mainly biomechanical/ergonomic and VDU) and the correct definition of their exposure levels is essential to adequately prevent the onset of WMSDs. In this regard, our findings provide useful information to design novel approaches, aimed at improving our understanding of emerging risks, identifying gaps in current risk assessment strategies and enhancing workplace interventions are mandatory to improve the occupational risk assessment and management process and therefore implement the subsequent health surveillance systems.

Physical environmental and occupational factors inducing work-related neck and shoulder pains among self-employed tailors of informal sectors in Ethiopia, 2019: results from a community based cross-sectional study

BACKGROUND

Musculoskeletal disorders (MSD) caused by occupational-related factors continue to place huge burdens on global workforces. Significant numbers of workers report potential adverse health outcomes related to the condition, such as physical injury, disability, and decline in quality of life. Occupational-related MSD also poses additional burdens to healthcare services and diminishes productivity at work. The condition usually worsens in informal sectors where the work environments are often poorly designed. This paper explored occupational and physical environmental factors that induce work-related neck and/or shoulder pains among self-employed tailors in Gondar city, Northwest Ethiopia.

METHODS

We conducted across-sectional survey from April to May 2019 on 422 tailors selected with systematic random sampling technique. Nordic Musculoskeletal questionnaire was used to measure pains in neck and/or shoulder, and the questionnaire was pretested and administered by interviewers. Work-related factors such as working posture, rest break, training in safety and health, and the availability of adjustable chairs at workplaces were assessed. The significance of associations was set at a < 0.05 p-value and adjusted odds ratios (AOR) with a confidence interval (CI) of 95% were used to determine strength of associations.

RESULTS

A total of 419 tailors participated with a response rate of 99.3%. The mean age and mean years of experience were 29.23 (SD ± 7.03) and 1.48 (SD ± 0.50) years, respectively. The study found that the prevalence of pain in either neck or shoulder or both sites in the last 12 months was 66.6% (N = 279) [95% CI (62.1, 71.1)]. Pains in shoulder and neck were observed in 72.1% (N = 302)[95% CI (67.8, 76.4)] and 68.3% (N = 286) [95% CI (64.0, 72.6)] of the interviewees, respectively. The majority, 78.1% (n = 218) of those with pains indicated they were prevented from doing normal daily activities. Work experience (AOR = 1.81), rest break (AOR = 2.13), awkward working posture (AOR = 2.60), prolonged sitting (AOR = 2.00) and inadequate light (AOR = 5.02) were significantly associated factors of neck and/ or shoulder pains.

CONCLUSION

Work-related neck and/or shoulder pain induced by physical factors of the work environment among self-employed tailors is pervasive in Ethiopia. Efforts to curb the condition, therefore, need to impalement diverse approaches addressing the physical environment and occupational factors. We also promote the integration of schemes for the effective use of rest breaks into health and safety programs in the workplace.

Prevalence of Musculoskeletal Disorders among Sewing Machine Workers in a Leather Industry

Background

Musculoskeletal disorders are the group of disorders which affects the muscles, tendons, ligaments, joints, peripheral nerves and supporting blood vessels in the body. Sewing machine involves continuous, repetitive tasks like cutting, assembly, pressing and finishing. These works are performed in a sitting posture with upper back curved forwards and the head is bent towards the sewing machine. Working in this faulty posture for a long time increases the chance of developing work related musculoskeletal disorder among them. The objective of study is prevalence of musculoskeletal complaints among sewing machine workers in leather industry.

Methods

A non- experimental study with 100 subjects according to inclusion and exclusion criteria. Using the NORDIC QUESTIONNAIRE musculoskeletal pain have been analysed.

Results

The statistical analysis of this study show 88% of sewing machine workers had a lower back pain in the last 12 months, 82% sewing machine workers had a lower back and knee pain that has been prevented them over last 12 months during normal activity, 86% sewing machine workers had lower back pain in the last 7 days.

Conclusion

This study concluded that the 86% experienced low back pain, 84% experienced knee pain and 74% of experienced neck pain in past 7 days. 88% of experienced low back pain, 86% experienced knee pain, 76% experienced neck pain in past 12 months.82% experienced pain in lower back and knee pain and 72% experienced neck pain among sewing machine manual workers that has impacted over last 12 months during normal activity.

Occupational health and safety hazards faced by healthcare professionals in Taiwan: A systematic review of risk factors and control strategies

Background

Healthcare professionals in Taiwan are exposed to a myriad of occupational health and safety hazards, including physical, biological, chemical, ergonomic, and psychosocial hazards. Healthcare professionals working in hospitals and healthcare facilities are more likely to be subjected to these hazards than their counterparts working in other areas.

Objectives

This review aims to assess current research literature regarding this situation with a view to informing policy makers and practitioners about the risks of exposure and offer evidence-based recommendations on how to eliminate or reduce such risks.

Methods

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses review strategy, we conducted a systematic review of studies related to occupational health and safety conducted between January 2000 and January 2019 using MEDLINE (Ovid), PubMed, PMC, TOXLINE, CINAHL, PLOS One, and Access Pharmacy databases.

Results

The review detected 490 studies addressing the issue of occupational health and safety hazards; of these, 30 articles were included in this systematic review. These articles reported a variety of exposures faced by healthcare professionals. This review also revealed a number of strategies that can be adopted to control, eliminate, or reduce hazards to healthcare professionals in Taiwan.

Conclusion

Hospitals and healthcare facilities have many unique occupational health and safety hazards that can potentially affect the health and performance of healthcare professionals. The impact of such hazards on healthcare professionals poses a serious public health issue in Taiwan; therefore, controlling, eliminating, or reducing exposure can contribute to a stronger healthcare workforce with great potential to improve patient care and the healthcare system in Taiwan. Eliminating or reducing hazards can best be achieved through engineering measures, administrative policy, and the use of personal protective equipment.

Implications

This review has research, policy, and practice implications and provides future students and researchers with information on systematic review methodologies based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy. It also identifies occupational health and safety risks and provides insights and strategies to address them.
