Factors associated with work-related musculoskeletal disorders in commercial motorcyclists

This study aimed to explore the prevalence of work-related musculoskeletal disorders (WMSDs) and to investigate factors associated with WMSDs in commercial motorcyclists in Indonesia. This cross-sectional study involved commercial motorcyclists operating in Indonesia. Data were collected using an anonymous questionnaire, including the Indonesian Version of the Nordic Musculoskeletal Questionnaire, occupational driving posture questionnaire, and occupational factor-related questions. The questionnaire was distributed at four rest stops located in Central Jakarta, Indonesia. The result showed that 40% of participants (129/322) were having WMSDs. Older age, overweight body mass index (BMI), obese body mass index, nonregular physical activity, driving duration (> 8 h/day), seniority (≥5 years), and poor driving posture were significant risk factors for WMSDs in commercial motorcyclists. Based on the risk factors identified in this study, the development of preventive strategies among commercial motorcyclists is warranted.

Self-Reported Work-Related Musculoskeletal Problems and Associated Risk Factors Among Three-Wheel Car Drivers in Ethiopia: A Cross-Sectional Community-Based Study

Background

Globally, the demand for mobility is increasing. Three-wheel cars are one of the best options for meeting this demand and creating new job opportunities in most developing countries, including Ethiopia. Drivers are highly susceptible to developing musculoskeletal disorders (MSDs). Even though several studies on other groups of drivers have been conducted, little is done in Ethiopia among three-wheel car drivers.

Objective

This study investigated the prevalence of MSDs and identified their associated risk factors among three-wheel car drivers in Ethiopia.

Methods

A community-based cross-sectional research was conducted among drivers of three-wheel cars from August 05 to October 07, 2022. A stratified sampling followed by a simple random sampling technique was used to select 422 respondents. Structured and pretested questionnaires adapted from the Nordic Musculoskeletal Questionnaire were used to collect the data. Epi-data version 4.2.0.0 and SPSS version 20 were used to enter and analyze the collected data, respectively.

Results

In the previous 12 months, 62.45% of three-wheel car drivers had musculoskeletal disorders in any body region (95% CI: 58.36, 66.14). The back pain was the most frequently reported site of pain in this study. This study showed that the habit of doing physical exercise, work experience, site of service, taking rest breaks while driving, and having comfortable sitting posture was risk factor for musculoskeletal pain.

Conclusion

In this study, the overall 12-month prevalence of musculoskeletal problems among three-wheel car drivers was high. Periodic health checkups for drivers, lifestyle changes, delivering training, and creating awareness are important to address this high-burden occupation-related problem.

Prevalence of work-related musculoskeletal disorders (WRMSDs) and its association with modifiable risk factors in metropolitan bus transit drivers: A cross-sectional comparison

Background

Bus drivers are one of the top three occupations with the highest prevalence of work-related musculoskeletal disorders (WRMSDs). The present study aimed to determine the pattern and prevalence of WRMSD among metropolitan bus transit drivers, whose job profiles differ from traditional long-distance bus drivers, and to explore the effect of modifiable lifestyle-related risk factors.

Materials and Methods

In this cross-sectional study, consenting 254 metropolitan transit bus drivers (with at least five years of job duration) and 73 age-matched indoor desk job workers (administration staff of the same department) as a comparison group enrolled. Sociodemographic and occupational profile were collected on a semi-closed questionnaire. A modified Nordic questionnaire was used to determine musculoskeletal problems. Anthropometric measurement and haematocrit estimation were performed with standard techniques. All statistical analyses including logistic regression were performed with SPSS 26.0.

Results

The prevalence of WRMSDs among bus drivers was twice higher than administration staff (49.2% v/s 28.8%). Drivers experienced significantly higher pain for the lower back (36.6% v/s 11%), knee (29.5% v/s 15.1%), and hip (7.5% v/s 1.4%) in comparison with administration staff. Study reported age, tobacco usage, body mass index (BMI) and job profile of drivers (compared to administration staff) as significant predictors of WRMSDs.

Conclusion

WRMSDs were significantly higher among metropolitan bus transit drivers in comparison with administrative staff. Furthermore, WRMSDs are strongly associated with tobacco use and BMI. These modifiable risk factors may be the targets for preventive strategies to reduce the burden of WRMSDs among bus drivers.

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.

Prevalence and associated factors of low back pain among taxi drivers in Gondar City, Northwest Ethiopia: a community-based cross-sectional study

OBJECTIVE

This study aimed to assess the prevalence of low back pain and associated factors among professional taxi drivers.

DESIGN

Community-based cross-sectional study.

SETTING AND PARTICIPANTS

A Modified Nordic Musculoskeletal Questionnaire was used to collect data. Through a simple random sampling technique, 371 taxi drivers were selected in Gondar City, Ethiopia.

DATA ANALYSIS

SPSS V.22 was used for data analysis. Bivariable and multivariable logistic regression analyses were used to identify the factors associated with low back pain. A p value less than 0.05 and an adjusted odds ratio (AOR) with 95% CI were used to declare statistical significance.

RESULT

A total of 371 respondents, with a response rate of 95.4%, have participated. The past 1 year and week's prevalence of low back pain among taxi drivers was 85.7% (95% CI 82.5 to 89.2) and 53.4% (95% Cl 48.0 to 58.5), respectively. Overweight/obese (AOR=0.33, 95% CI (0.14 to 0.80)), alcohol drinking (AOR=4.77, 95% CI (1.16 to 19.5)), job dissatisfaction (AOR=4.58, 95% CI (1.39 to 15.2)), prolonged working hours per day (AOR=2.64; 95% CI (1.02 to 6.08)), not using the adjustable seat with back support (AOR=6.38, 95% CI (2.39 to 17.01)) were associated with low back pain among taxi drivers.

CONCLUSION

The prevalence of low back pain among taxi drivers was high. Being overweight/obese, alcohol drinking, job dissatisfaction, prolonged working hours per day, and not using adjustable seats with back support, were factors associated with low back pain among taxi drivers. Therefore, ergonomic and behavioural-related awareness training is recommended to minimise the burden of low back pain among taxi drivers.

Causal Relationship Between the Risk Factors and Work-Related Musculoskeletal Disorders Among Professional Drivers: A Systematic Review

OBJECTIVE

This review evaluates the evidence on the strength of causal relationship between categories of risk factors (RFs) and work-related musculoskeletal disorders (WRMSDs) among professional drivers.

BACKGROUND

A compilation of evidence on the causal relationship between RFs and WRMSDs among professional drivers is lacking.

METHODS

A systematic search of the literature was conducted in major electronic data bases that include Medline (1946 + via OvidSP), Embase (1974 + OvidSP), CINAHL (1982+), AMED, and Web of Science. The methodological quality of the studies was assessed and scored. A descriptive analysis on the categories of RFs associated with WRMSDs was conducted. The Bradford-Hill causation criteria and evidence interpretation tool were used to evaluate the causal relationship between RFs and WRMSDs in professional drivers.

RESULTS

Among the 54 studies reviewed, a strong evidence suggests a causal relationship between RFs such as whole-body vibration, awkward postures, lifting tasks, manual material handling, job stress, job demand, and previous pain episodes with WRMSDs. Moderate evidence was observed on RFs such as uncomfortable seat and low job satisfaction. The evidence on causal relationship between RFs such as years of professional driving, driving duration, and individual characteristics such as age and body mass index was inconclusive.

CONCLUSION

There is strong to moderate evidence on the causal relationship between the physical and psychosocial RFs and WRMSDs among professional drivers.

APPLICATION

Potential application of this review highlights evidence to occupational health practitioners, policy makers, and stakeholders on the strength of causal relationship between RFs and WRMSDs among professional drivers.

Self-Reported Musculoskeletal Disorder Symptoms among Bus Drivers in the Taipei Metropolitan Area

Bus driving is considered a highly stressful and unhealthy occupation, even among sedentary jobs, because of the particular task characteristics. This study used the Nordic Musculoskeletal Questionnaire (NMQ) to interview bus drivers and determine the risk factors for musculoskeletal discomfort. The NMQ was distributed to 152 bus drivers in the Taipei metropolitan area (Taiwan) and the valid data of 145 respondents were analyzed. The survey revealed that the overall prevalence of musculoskeletal disorder symptoms in any body part during the preceding year was 78.3%, and the body parts for which with the prevalence of discomfort was highest were the neck (46.9%), right shoulder (40.0%), lower back (37.2%), and left shoulder (33.8%). Stress and an uncomfortable seat may contribute to neck, shoulder, and lower back discomfort. Stretching between trips may help to reduce neck and shoulder discomfort. When comparing our results with those of similar studies, we discovered that the prevalence of symptoms and detailed risk factors vary by country and region. On this basis, we believe that local investigations emphasizing specific task arrangements and characteristics are needed to address the problem of musculoskeletal disorders in bus drivers.

Prevalence of musculoskeletal pain and associated disability among professional bus drivers: a cross-sectional study

Purpose

Professional bus drivers risk developing musculoskeletal pain (MSP) and disability due to their working condition. The current study investigates the prevalence rate of MSP and disability among professional bus drivers.

Methods

A cross-sectional study was conducted among 83 professional bus drivers. The prevalence rate of MSP was evaluated using a standardized Nordic musculoskeletal questionnaire. The disabilities due to the MSP were evaluated using neck disability index (NDI), Oswestry disability index (ODI) and shoulder pain and disability index (SPADI) tools. Prevalence of MSP was presented with 95% of confidence interval (CI) at an alpha level of 0.05. The 12 months and 7 days prevalence of MSP were tabulated for analysing the trend of MSP between the upper and lower body regions.

Results

The drivers had a mean driving experience of 10.07 ± 7.26 years. The mean driving hours/week were 50.25 ± 12.82 h. Neck and back were the most affected regions with a prevalence rate of 81.9% (N = 68) and 80.7% (N = 67) at 12 months. Back region recorded the highest 7 days prevalence rate for MSP with 53% (N = 44). Approximately one fourth of the bus drivers population (23.9%, N = 16) had moderate disability in back region. More than half with MSP in the neck region presented mild disability (54.4%, N = 37).

Conclusion

The bus drivers reported a high prevalence rate of MSP in the neck, back and shoulder regions with mild to moderate disabilities. Appropriate health care and rehabilitation programs are necessary for the prevention and management of MSP among the bus drivers.

Prevalence of musculoskeletal pain among professional drivers: A systematic review

OBJECTIVES

Professional drivers are at high risk of developing musculoskeletal pain (MSP) due to risk factors such as prolonged sitting, whole body vibration, awkward posture, and repetitive actions. This review investigates the reported prevalence of MSP among professional drivers.

METHODS

An electronic search of Medline (1946 + via OvidSP), Embase (1974 + OvidSP), CINAHL (1982+), AMED, PubMed, and Web of Science from 1990 to July 2019 was performed. Methodological quality of studies was assessed using three quality assessment tools for cross-sectional, case-control, and prospective cohort studies. The prevalence of MSP was reported using descriptive analysis.

RESULTS

A total of 56 studies conducted in 23 different countries across a total of 14 types of occupational transport were reviewed. Data of a total pooled population of 18 882 professional drivers were analyzed for MSP. The prevalence of MSP ranged between 43.1% and 93%. The low back was the most frequently reported body region for MSP with a meta-prevalence rate of 53% (N = 9998). Neck, shoulder, and upper back were the other common regions with high prevalence.

CONCLUSION

There is a high prevalence of MSP in professional drivers and low back was the most frequently reported body region, followed by neck, upper back, shoulder, knee, hip/thigh, wrist, ankle, and elbow. MSP is complicated in nature and therefore in-depth exploration of causal relationships between MSP and risk factors is necessary so that appropriate healthcare programs can be initiated to prevent and treat MSP effectively.
