Assessment of Risk Factors for Musculoskeletal Pain Among University Staff Members.

Prevalence and Risk Factors for Musculoskeletal Pain in Keyboard Musicians: A Systematic Review

BackgroundOccupational use of computers has increased rapidly over recent decades, and has been linked with various musculoskeletal disorders, which are now the most commonly diagnosed occupational diseases in Estonia. The aim of this study was to assess the prevalence of musculoskeletal pain (MSP) by anatomical region during the past 12 months and to investigate its association with personal characteristics and work-related risk factors among Estonian office workers using computers.MethodsIn a cross-sectional survey, the questionnaires were sent to the 415 computer users. Data were collected by self-administered questionnaire from 202 computer users at two universities in Estonia. The questionnaire asked about MSP at different anatomical sites, and potential individual and work related risk factors. Associations with risk factors were assessed by logistic regression.ResultsMost respondents (77%) reported MSP in at least one anatomical region during the past 12 months. Most prevalent was pain in the neck (51%), followed by low back pain (42%), wrist/hand pain (35%) and shoulder pain (30%). Older age, right-handedness, not currently smoking, emotional exhaustion, belief that musculoskeletal problems are commonly caused by work, and low job security were the statistically significant risk factors for MSP in different anatomical sites.ConclusionsA high prevalence of MSP in the neck, low back, wrist/arm and shoulder was observed among Estonian computer users. Psychosocial risk factors were broadly consistent with those reported from elsewhere. While computer users should be aware of ergonomic techniques that can make their work easier and more comfortable, presenting computer use as a serious health hazard may modify health beliefs in a way that is unhelpful.

Dentists have a high prevalence of musculoskeletal (MS) pain, which is the most common symptom associated with work-related musculoskeletal disorders (WMSDs). To overcome this problem, identification of the risk factors and preventive measures for MS pain are of paramount importance to dentists in order to improve their quality of life and work. The aims of this study were to recognize the risk factors for MS pain and their impact on dental work, as well as to identify preventive measures of MS pain among dentists. Self-reporting questionnaire consisting of 78 questions was exclusively developed for the study and sent to 500 working active dentists in Serbia. Response rate was 71.2% (356 dentists). The prevalence of MS pain was 82.6% among dentists. The main risk factors for MS pain were advanced age, female dentists, presence of chronic diseases, long working hours, and high frequency of treated patients. The most effective preventive measures in preventing MS pain were massage treatments and physical activities. Followed by use of ergonomically designed equipment, correct and dynamic working positions, and an adequate workflow organization. The risk factors for MS pain and their impact on dental work should widely be disseminated among dentists. Importantly, proper implementation in everyday life of adequate preventive measures is essential for preventing MS pain and development of WMSDs.

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

Musculoskeletal disorders (MSDs) are the most common cause of severe long-term pain and physical disability. High prevalence of musculoskeletal pain among medical and other health science students has been reported globally. However, little is known about the magnitude of the problem in Ethiopia among medical and health science students. Therefore, this study aimed to determine the prevalence and identify the associated risk factors of MSDs among medical and health science students in Ethiopia. Institution based cross-sectional study was conducted from March to May 2018. A stratified random sampling technique was applied to select 422 study participants, and the data was collected by a standardized Nordic questionnaire for the analysis of musculoskeletal symptoms. Bivariate and multivariable binary logistic regression analyses were performed using SPSS version 20. The prevalence of musculoskeletal disorders in any part of the body region among medicine and nursing students was 69.4% (95% CI, 64.9, 73.9). Lower back pain was the most commonly reported body site and its prevalence increased as the year of study increases, ranging from 38% among 2nd year to 74.4% among 5th-year students. As the year of study/academic year increased, the odds of developing musculoskeletal disorders were higher. Furthermore, this study showed that a poorly designed sitting chair was a risk factor for musculoskeletal pain. Ergonomic interventions focusing on modification of workstations, and promoting and delivering ongoing ergonomic education are very important to reduce the problem.

Development of ergonomic risk factors (physical and psychosocial) questionnaire among preschool teachers' work environment.

ObjectivesMusculoskeletal pain is recognized as a major occupational health hazard among dentists worldwide. Physical exertion at work plays a major role in the development of musculoskeletal problems. There is growing evidence that work-related psychosocial factors may also contribute to musculoskeletal pain. Therefore, the aim of this study was to investigate the prevalence of work-related musculoskeletal pain and its demographic, physical, and psychosocial risk factors among dentists in Jordan.MethodsThis cross-sectional study utilized a validated self-administered questionnaire distributed to 272 currently working Jordanian dentists. The questionnaire consisted of four sections: sociodemographic information, work physical characteristics, work-related psychosocial factors, and musculoskeletal pain assessment.ResultsFifty-one percent (51%) of Jordanian dentists reported experiencing musculoskeletal pain in the last 12 months. Neck pain (42%), followed by shoulder pain (40%), and lower back pain (40%), were the most common among dentists in Jordan. Increasing age, being a female, and obesity were significantly associated with musculoskeletal pain while smoking, exercise, and specialty level did not. A positive correlation between musculoskeletal pain and unfavorable physical characteristics at work was identified. In addition, increased work stress was positively correlated with musculoskeletal pain.ConclusionThis study showed a high prevalence of musculoskeletal pain among Jordanian dentists. Increasing dentists' and healthcare authorities' awareness about factors associated with work-related musculoskeletal pain is needed. Educational programs targeting dentists at risk of developing musculoskeletal pain might be of potential preventive value.

Associations between physical or psychosocial risk factors and work-related musculoskeletal disorders in construction workers based on literature in the last 20 years: A systematic review

ObjectiveThe aim of this study is to determine the risk factors related to upper extremities work-related musculoskeletal disorders (WRMSDs) in cameramen.MethodsA questionnaire survey was performed on 166 cameramen in a broadcasting station. The questionnaire consisted of questions on the general characteristics, the health behavior, work type and duration, physical burden, ergonomic posture, and musculoskeletal symptoms. Definition of musculoskeletal disorders was based on NIOSH criteria.ResultsThe positive rate of WRMSDs symptoms by parts of the body was turned out to be the highest in the shoulder (14.5%) and the lowest in arm and elbow (6%). Logistic regression analysis revealed that symptoms in the shoulders increased with BMI (OR = 3.62, 95% CI = 1.03-12.71), physical burden (OR = 9.29, 95% CI = 1.72-61.78 in the very hard group) and ergonomic factors (OR = 4.50, 95% CI = 1.03-19.68). Ergonomic factors were only related to the symptoms of hand and wrist (OR = 10.21, 95% CI = 1.02-102.20). WRMSDs symptoms, in the whole upper extremities, were higher in the 50 or older age group (OR = 5.86, 95% CI = 1.03-33.26), higher BMI group (OR = 3.26, 95% CI = 1.28-13.53), non-exercise group (OR = 2.37, 95% CI = 1.24-12.59), high physical burden group (OR = 7.6, 95% CI = 1.34-52.74), and high grade ergonomic risk group (OR = 4.82, 95% CI = 1.29-16.06).ConclusionThe most serious musculoskeletal disorders of male cameramen were shoulder pain. Ergonomic factors and physical burden were the most significant factors affecting WRMSDs in cameramen in this study. Cameramen should be educated to be able to improve the ergonomic occupational environment and to set up preventive measures against the risk factors during work.

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.

Musculoskeletal (MSK) pain is a debilitating multi-perceptual condition afflicting many individuals, especially individuals in the medical profession. To analyze and evaluate the prevalence of musculoskeletal pain among medical students at Jordanian universities during the complete virtual learning process. A cross-sectional study of 593 medical students at two Jordanian universities was conducted. A modified Nordic questionnaire was used to assess musculoskeletal pain in three body regions. Five hundred ninety-three students at the two Jordanian universities participated in this study. The prevalence of having MSK pain during the past week in the neck, shoulder, and lower back was 34.6%, 27%, and 41%, respectively; during the past 12 months, it was 61.2%, 45.5%, and 63.1%, respectively. Overall prevalence of having MSK pain was 58.9% in the last week and 78.1% in the past 12 months. 66.8% of students who had psychosomatic symptoms and 62.3% of those with depressive symptoms in the past week had MSK pain. Students who studied 8 hours per day had higher percentages of MSK pain (68.4%) (OR 1.12, 95% CI 0.965-1.312). The average number of hours using a computer per day was significantly associated with MSK pain (p= 0.032). MSK pain during the last week was significantly associated with psychosomatic symptoms (OR 1.842, 95% CI 1.272-2.668, p= 0.001). Family history of MSK pain was significantly related to the presence of the problem in participants (OR 1.732, 95% CI 1.182-2.538, p= 0.005). Gender, depressive symptoms, average hours of computer use per day, and average hours of study at home per day did not show significant relationships with MSK pain over the year. High prevalence of MSK pain was observed among medical students. Measures to balance in-person and virtual learning should be considered in medical schools to minimize the risk of MSK pain.

Musculoskeletal (MSK) pain is a common reason for consultation in general practice and frequently reported in children and adolescents. This study examined the prevalence of MSK pain in 13-year-old children and assessed associations with physical and psychosocial factors. Data from the Generation R Study, a population-based birth cohort, was used. Prevalence and characteristics of MSK pain were assessed, using a pain mannequin, at 13 years of age (N = 3062). Demographics and data on physical activity, sedentary behaviors, previous reported MSK pain, and behavioral problems were extracted from questionnaires. The body mass index (BMI) SD-score was calculated from objectively measured weight and height. A prevalence of 23.3% was found for MSK pain in children of which 87.2% persisted for more than 3 months (ie, chronic), 45.5% experienced pain daily. More physically active children and children with a higher BMI reported MSK pain more frequently compared with non-MSK pain and no pain. The knee was the most often reported location. Children with MSK pain were more likely to have reported MSK pain at 6 years. Multivariable analyses showed significant associations for male sex (OR 0.74, 95% CI 0.56-0.98), high maternal educational (OR 0.69, 95% CI 0.49-0.96), higher BMI (OR 1.19, 95% CI 1.05-1.35), being physically active (OR 1.41, 95% CI 1.03-1.91), and behavioral problems (OR 1.85, 95% CI 1.33-2.59) with the presence of MSK pain. The chronic nature of MSK pain in combination with the relatively high prevalence of MSK pain in this study shows that MSK pain is already an important problem at a young age.

Background: In dentistry, musculoskeletal (MSK) pain creates a significant occupational health hazard jeopardizing the efficient delivery of care to the patients. There are several factors linked to the job that contribute to the higher incidence of MSK pain among dental practitioners. Uncomfortable postures and movements, frequent and prolonged working hours, the amount of time spent with each patient are some of the work-related factors of work related lower back pain which need to be addressed to prevent the disabling effects in the long run. The study aims to evaluate the prevalence of work related lower back pain and significance of associated risk factors in Saudi Arabia. Methods: Self-administered questionnaire were distributed to 384 dental practitioners who were working in various clinics in Saudi Arabia. This survey had four sections with questions related to demographic data, clinical practice, ergonomic principles, and psychosocial impacts. Descriptive statistics including chi-square analyses and associated significance were performed. Results: The relationship between age, years of experience and back pain among dental professionals was found to be significant with back pain lasting between 1 to 7 days in 34.2% among the participants. Older individuals with more experience tend to use back braces, analgesics, and physiotherapy more often. The cumulative prevalence of back pain in the study was 42.2%, with the majority of participants working for 2-8 hours per day. Various types of back strain injuries were observed across age groups and experience levels. Psychosocial impacts like job dissatisfaction and missed workdays were more pronounced in older individuals. The type of dental work and sitting posture also influenced back pain in specific age groups with significant associations observed. Conclusions: Our study sheds light on the significant issue of MSK pain among dental practitioners in Saudi Arabia, emphasizing its complex nature involving physiological, ergonomic and psychosocial factors. Found high prevalence of MSK pain, especially lower back discomfort, linked to factors like sitting postures and long working hours.

A cross‐sectional study was conducted to evaluate the association between work‐related musculoskeletal disorders (WRMDs) and work conditions, perceived exhaustion, job dissatisfaction, and job‐stress issues at two teleservice centers (TSCs). The study covered teleservice representatives who respond to toll‐free calls for assistance. The work involves a computer or manual search for information, and data entry using keyboards. One facility had upgraded the furniture at the workstations; the other facility had not. A questionnaire survey among 114 teleservice representatives and an ergonomic evaluation were conducted to determine WRMDs and their risk factors and perceived job stress. A high prevalence of symptoms of WRMDs was found at both TSCs. Suboptimal ergonomic conditions were associated with neck, shoulder, elbow, and back WRMDs, as well as with increased job dissatisfaction. Perceived increased workload variability and lack of job control were associated with the occurrence of neck and back WRMDs, respectively. WRMDs were more frequently reported by teleservice representatives at the center with older furniture and suboptimal ergonomic conditions. WRMDs may be prevented by improving ergonomic conditions at workstations and addressing work‐organization elements.

Work-related musculoskeletal disorders are defined as the disabling or painful injury to the muscles, nerves or tendons that are caused by work or aggravated by it. Some studies confirm the association between working in packaging units in various industries and the pain in the upper limb, but also there are controversies about the possible risk factors among different working populations. The present study aims to define the potential ergonomic risk factors for musculoskeletal pain in the upper limb. The Nordic Musculoskeletal Questionnaire was used for assessment of the musculoskeletal pain. Some other questions about the possible risk factors were included in the questionnaire. In order to assess posture, rapid upper limb assessment (RULA) test was performed by trained ergonomists. The findings of the study reveals that shoulder pain is associated with work history (P-value = 0.01), smoking (P-value = 0.02), the level of education (P-value = 0.04) and age more than 40 years old (P-value = 0.01). Wrist pain was associated with shiftwork (P-value = 0.04) and especially fixed shiftwork (P-value = 0.04) and also age more than 40(P-value = 0.03) and missed days from work with a cut point of 7 days (P-value = 0.03). After regression, only the work history (OR = 14.4 for 10 to 20 years and OR = 32.2 for more than 20 years) and shiftwork (OR = 2.35) remained statistically significant. In this study, RULA was not associated with symptoms in the upper limb in non-heavy working industries so we do not recommend it for screening purposes. The use of decades of working history and shiftwork can be considered for this purpose in the shoulder and wrist pain respectively.
