Investigation Of Ergonomic Risk Factors Among Male Workers In A Medical Manufacturing Company In Northern Malaysia

@#The medical manufacturing industry is currently one of the sectors with great potential growth in Malaysia, which offers numerous job opportunities to local and foreign workers. The growing proportion of workers in this industry means that a large number of workers are potentially exposed to ergonomic risk factors at the workplace, which may consequently affect their health. Thus, this study was carried out is to investigate the ergonomic risk factors and the prevalence of musculoskeletal disorders among male workers in a medical manufacturing company in northern Malaysia. Eight industrial workers (n = 8) were recruited from two Plastic Technology (PT) departments to participate in this study. Observations were made by recording the participants performing two tasks (manual lifting of containers and bags of chemicals) using a video camera at the PT1 and PT3 departments. The participants’ personal information and their job-related characteristics were first collected using a demographic questionnaire. Next, the Cornell Musculoskeletal and Hand Discomfort Questionnaire (CMDQ) was used to evaluate the prevalence of musculoskeletal disorders among workers while Manual Handling Assessment Charts (MAC) were used to assess the most common risk factors during the lifting operations. The results showed that the highest prevalence of musculoskeletal disorders among the male workers at the medical manufacturing company was at the lower back (83.17%), upper back (4.38%), right shoulder (3.49%), and left shoulder (3.49%). Based on the results of the MAC, 100% of the participants were at high risk of injury from postures in the vertical lift zones, torso twisting, and sideways bending. In addition, 87.5 and 62.5% of the participants were at high risk of injury based on their hand distance from the lower back and grip on the load, respectively. The results of this study can serve as a guideline to implement interventional ergonomics programmes at the workplace and improve the musculoskeletal health of workers in the medical manufacturing industry in Malaysia.

Risk Assessment and Intervention of Ergonomic Risk Factor in Beekeeping / 農村醫學 地域保健

OBJECTIVES: The purpose of this study was to assess the ergonomic risk factors in beekeeping, and to evaluate the effectiveness of assistive device hive lift. METHODS: This study included 30 subjects of beekeeper in Pocheon, Korea. We assessed the ergonomic risk of main task in beekeeping with NLE, OWAS and evaluate the effectiveness of hive lift. We also surveyed prevalence of musculoskeletal symptoms among the subjects based on the Korea Working Condition Survey. RESULTS: Moving to different floral origin, internal inspection of beehives, feeding syrup is the most burdensome to musculoskeletal system (NLE LI value=2~3. OWAS action category=4). The prevalence of musculoskeletal symptoms (lower and upper extremities) among the subjects was over 80 %. The introduction of assistive devices in the three hazardous tasks has dramatically reduced the risk by removing manual lifting hives (OWAS action category<1). CONCLUSIONS: Beekeeping is a heavy workload on the musculoskeletal system because it has a lot of manual lifting task. As a result of applying the hive lift, the burden could be reduced.

Relationship between simultaneous exposure to ergonomic risk factors and work-related lower back pain: a cross-sectional study based on the fourth Korean working conditions survey

BACKGROUND: It is well known that ergonomic risk factors and back pain are related. However, few studies have examined the relationship between simultaneous exposure to these risk factors and back pain in a Korean population. We aimed to investigate the relationship between simultaneous exposure to ergonomic risk factors and work-related lower back pain (LBP) based on the fourth Korean Working Conditions Survey (KWCS). METHOD: The fourth KWCS (2014) was used for this study. Chi-square tests and logistic regression were used to assess relationship between 5 ergonomic risk factors and work-related LBP. We also analyzed the relationship between simultaneous exposure to 2 risk factors and work-related LBP. RESULTS: All 5 ergonomic risk factors (fatigue-inducing and painful posture; lifting or moving people; dragging, pushing, or moving heavy objects; standing posture; and repetitive hand or arm movements) were significantly correlated with work-related LBP in the severe exposure group (adjusted odd ratios [aOR] 5.09, 95% confidence interval [CI] 4.46–5.83; aOR 1.98, 95% CI 1.62–2.42; aOR 2.09, 95% CI 1.82–2.40; aOR 1.79, 95% CI 1.60–2.01; aOR 2.04, 95% CI 1.82–2.30, respectively). When exposed to 2 risk factors simultaneously, the relationship between exposure and work-related LBP was not greater than exposure to only 1 risk factor in our study (usually exposed to ‘fatigue-inducing or painful posture’ aOR 2.17, 95% CI 2.02–2.34; high exposure to both ‘fatigue-inducing or painful posture’ and ‘dragging, pushing, or moving heavy objects’ aOR 2.00, 95% CI 1.82–2.20). CONCLUSIONS: There was a strong relationship between severe exposure to each ergonomic risk factor and work-related LBP. However, when exposed to 2 ergonomic risk factors simultaneously, the relationship between exposure and work-related LBP was not stronger than when exposed to only 1 risk factor in our study.

Introduction: Workers of the metallurgical industry are constantly exposed to occupational risk factors that can lead to the development of work-related musculoskeletal disorders (WMSDs). These disorders are highly debilitating, generating losses to workers, companies and the State. Objective: To identify and verify the connection between risk factors and WMSDs in metallurgical workers in the manufacture of machinery and equipment. Method: This is a cross-sectional epidemiological study that involves registered workers of the Occupational Health Reference Service (Cerest) in São Paulo state. The survey was conducted through review of electronic medical records. Results: 2116 electronic medical records were analyzed, from these, 36 were considered for the sample. We observed that 91.6% (n = 33) of the participants were men, age range from 29 to 62 years and the most prevalent occupational status was unemployment (47.3% (n = 17)). The WMSDs were found in the upper limbs and spine region, predominantly spine. Repetitiveness was the most prevailing risk factor (94.4% (n = 34)). A connection between repetitiveness (p = 0.0046) and physical exertion (p = 0.001) with symptoms in the spine was detected. Conclusion: The spine is the main body region affected in these workers. There was a link between repetitiveness and physical exertion with the symptoms of spine pain. The results strengthen the need for interventions in the workplace to minimize repetitive work and excessive physical exertion seeking prevention and workers' health promotion.

Assessment Of Ergonomic Risk Level And Working Performance Of Pre-Cast Construction Workers In Sabah

@#A cross-sectional study was conducted on 116 male pre-cast construction workers in Sipitang, Sabah to evaluate the association between Ergonomic Risk Level exposure and their working performances for 6 months (June to November 2014). Initially, a structured interview using a modified-Standardized Nordic Questionnaire was conducted on each study subject to determine the prevalence of Musculoskeletal Disorders (MSDs). The results showed that 93 out of 116 subjects (80.17%) complained of experiencing ache, pain or body discomfort during and after work with high percentage of MSDs prevalence affecting the wrist (78.5%), shoulder (73.1%), and lower leg (71.0%) regions of the body. Pictures and videos of workers performing their routine tasks were analyzed using Rapid Entire Body Assessment (REBA) tool to generate individual Ergonomic Risk Level classification. The results showed that all subjects were exposed to Medium (56.90%), High (29.31%) and Very High (13.79%) level of Ergonomic Risk. Pearson Correlation and One-way ANOVA test was conducted to determine the association between Ergonomic Risk Level and the subjects’ individual working performances. The results indicated that there was a significant negative association between Ergonomic Risk Level and the workers' performances in terms of tendency to work overtime (p<.001, r=-.55) and the frequency of taking unpaid leaves (p=.038, r=.56). In conclusion, continuous exposure to significant Ergonomic Risk Level among the pre-cast construction workers has triggered the development of MSDs which eventually affected their working performances.

Una relación directa entre el nivel de riesgo ergonómico, por levantamiento incorrecto de cargas excesivas, adopción de posturas forzadas y movimientos repetitivos con patologías músculo esqueléticas. Discusión: Debido a la aplicación de mecánica corporal inapropiada y a la falta de medios auxiliares de movilización de pacientes, el personal de salud está expuesto a riesgos altos y muy altos de sufrir lesiones musculoesqueléticas. Se sugiere educación continua para reducir riesgos y evitar lesiones adquiridas en el trabajo.

Introduction: Lately in Ecuador, occupational health has become relevant to hospital managers. The policy of preventing risks is taking steps ahead to minimize them. Hospitals are places where personnel that routinely handle patients are exposed to physical risks than could lead to musculoskeletal disorders, affecting mainly back and shoulders. The staff frequently suffers pain in the lower back area, due to several factors like adopting incorrect postures, use obsolete equipment, shortage of staff and working in confined spaces. Such lesions may occur anywhere on the body but the more sensitive areas are the upper limbs and the lower back. Methods: This study was carried out at Carlos Andrade Marín Hospital in order to assess health personnel risks when they routinely handle patients. Surveys using previous validated tools like Mobilization Healthcare Inpatient (MAPO) and Rapid Entire Body Assessment (REBA) were employed to assess the degree of risk involved in hospital work, specially when adopting awkward postures, strain efforts or repetitive movements that cause musculoskeletal lesions. Results: Some scales allow us to detect important risk factors that endanger the health of hospital workers. There is a direct relationship between ergonomic risks due to manual patient handling, including lifting, repositioning, transferring, etc., with musculoskeletal disorders. Discusion: The use of inapropiate body mechanics and the lack of auxiliary methods to move patitents, health personnel is exposed to bone and muscle injuries. Continuous education is recommended to control risks and minimize working injuries.

The Prevalence of Musculoskeletal Symptoms and the Ergonomic Risk Factors among Oriental Melon-growing Farmers / 대한산업의학회지

OBJECTIVES: The purpose of this study was to investigate the prevalence of musculoskeletal symptoms in oriental melon-growing farmers and to evaluate the ergonomic risk factors of melon cultivation. METHODS: The study included 217 subjects growing oriental melons mainly in 3 villages. Subjects were interviewed by means of a structured questionnaire. Instruments used the general features and symptom table of NIOSH to evaluate tasks using ergonomic tools (REBA, OWAS). RESULTS: A total of 202 final respondents answered. The prevalence of musculoskeletal symptoms based on the NIOSH standard criteria was 162 (75.2%). The prevalence per body part for lower back, knee and shoulder were 102 (50.5%), 86 (42.6%) and 71 (35.1%), respectively. The prevalence of pain complaints of the musculoskeletal symptom was 91 (45.0%). The prevalence of complaints per body part of lower back, knee and shoulder were 54 (26.7%), 41 (20.3%) and 37 (18.3%), respectively. Logistic regression analysis showed men were at higher risk compared to women (OR=2.409, 95% CI=1.071~5.389), and ore than 30 years of work having a higher risk compared to less than 30 years of work (OR=2.445, 95% CI=1.150~5.197). High risk tasks were moving around boxes and nursery plants for planting, transplanting nursery plants, and picking melons. CONCLUSIONS: Musculoskeletal symptoms were very highly prevalent in oriental melon-growing farmers, showing up in 75.2% of cases. They were exposed to ergonomic high risk factors such as squatting. These risk factors must be improved in some way.
