Work related musculoskeletal disorders (MSDs) are a cause of concern because of the ill health effects and high economic impact on businesses. Manual Material Handling (MMH) jobs are common in informal sector of developing countries. The present study was carried on the workers of a central market area in Kolkata to find out the prevalence of the MSD. 210 male MMH workers were randomly selected. Standardized Nordic Musculoskeletal questionnaire was used to assess the prevalence of MSD. Working posture was analyzed by Ovako working posture analysis system (OWAS). SF12 questionnaire was used to assess the physical and mental health status. Lower back was found to be worst affected body part (68 %) followed by Knee (63%), Neck (56%) and Shoulder (41%). The Physical composite score (PCS) and Mental composite score (MCS) were found to be 39.7 ± 9.11 and 46.0 ± 9.17 respectively. PCS, MCS and Frequency of lifting were found to be significant predictors of pain intensity rating. The regres...

Work related musculoskeletal disorders (WRMSD) have been reported by many people from all over the world. The direct as well as indirect costs associated with WRMSD as for the compensation purpose is relatively high in value and the effect of it both to the employees and companies are very much significant. Major research studies have only concentrated on the effect of ergonomics to WRMSD. However, more researches have come into surface for the study of the relationship between psychosocial stress factors at workplace with WRMSD. In this research study, there are 6 variables under the psychosocial risk factors which being set and determined as independent variables whereas WRMSD being set as dependent variable. The 6 factors mentioned here are job demand (JD), role expectation (RE), work control (WC), social interaction (SI), leadership influence (LI), as well as organizational culture (OC). A total of 50 sample sizes have been taken and the correspondents comprised of employees wor...
Background: Rapid technological development in the use of electronic data has affected both the employees and workplace. In recent years rapid use of computers has changed the work environment drastically. Various personal factors, work related factors (WRF), psycho-social factors (PSF) can result in many health hazards like musculoskeletal disorder (MSD). From the literature review it is observed that the musculoskeletal disorder is very common among bank employees. Objective: The purpose of this paper was to examine the impact of these factors on the prevalence musculoskeletal disorder. Material and Method: A self designed questionnaire based on Nordic musculoskeletal disorder was delivered to sixty employees of state bank of India distt. Nawanshahr Punjab. Out of which fifty questionnaires were completely filled and ten questionnaires were partially filled and thus not included in the study. Association of risk factor was accessed by Logistics regression, chi-square, and using SP...
INTRODUCTION The World Health Organization has characterized "work-related" diseases as multifactorial to indicate that several risk factors (e.g., physical, work organizational, psychosocial individual, and sociocultural) contribute to causing these diseases [1]. "Musculoskeletal disorders'' include a wide range of inflammatory and degenerative conditions affecting the muscles, tendons, ligaments, joints, peripheral nerves, and supporting blood vessels. Musculoskeletal disorders (MSDs) are widespread in many countries, with substantial costs and impact on quality of life [2]. MSDs occur in certain industries and occupations with rates up to three or four times higher than the overall frequency. High-risk sectors include nursing facilities; air transportation; mining; food processing; leather tanning ; and heavy and light manufacturing (vehicles, furniture , appliances, electrical and electronic products, textiles, apparel and shoes) [3] Upper extremity musculoskeletal disorders are also highly prevalent in manual-intensive occupations, such as clerical work, postal service, cleaning, industrial inspection and packaging 4. Back and lower limb disorders occur disproportionately among truck drivers, warehouse workers, airplane baggage handlers, construction trades, nurses, nursing aides and other patient-care workers, and operators of cranes and other large vehicles [4, 5]. ABSTRACT Introduction: Musculoskeletal disorders are a major public health problem in industrialized and developing countries. The present study was aimed to find out the prevalence of acute and chronic WMSD's in Industrial workers. Methodology: This cross-sectional observational study was carried out in 60 workers of the Adon Block department workers of the electrical & automation industry, Ahmednagar. Pre-structured occupational Performa was filled by asking questions in the worker's local language. The Nordic pain Questionnaire was filled by asking the subjects to mark the sites of pain on body chart paper. The risk factors for work-related musculoskeletal problems were assessed by the working posture of workers and repetitive movements in industrial set up. The data collected were interpreted and analyzed. Results: In the present study, 60 workers were selected, of which a number of females were 39 (65%) while males were 21 (35%). The Neck (20.2%) followed by the shoulder (14.9%), elbow (14.4%) and knee (14.4%) were most commonly involved. There was a statistically significant variation in the number of workers involved according to the posture (sitting vs standing) and part of the MSK system involved. Conclusion: The WMSD's are common in Adon block department workers. The involvement of neck, shoulder, lower back and arm was common in sitting position, while the involvement of upper back, elbow and knee were common in standing position. The disorders are commonly seen in workers irrespective of their duration of work and gender..

"Background: Work-related musculoskeletal disorders (WMSDs) have been documented in various occupational groups in Iran. However, there is a gap in the studies regarding the prevalence of WMSDs, occupational stress, and general health in workers. The present study aimed to investigate the correlations between WMSDs, occupational stress, and general health. Methods: This cross-sectional study was conducted on 455 workers selected from various industries in 10 cities in Iran. Data were collected using self-reported measures to evaluate the body map, HSE management standards indicator tool, and general health questionnaire (GHQ). Results: In total, 455 questionnaires were completed and analyzed. The mean differences were compared using the Kruskal-Wallis test. The results of Spearmanchr('39')s correlation-coefficient indicated a significant, positive correlation between WMSDs and occupational stress. In addition, negative correlations were observed between general health, WMSDs, and occupational stress. Conclusion: Some of the recommendations based on the findings are modifying the workplaces of individuals who perform long-term, static tasks, periodic identification of the individuals with musculoskeletal problems and taking measures to correct their posture, designing proper physical exercises for the individuals with hard work postures, and cognitive-behavioral education to raise awareness regarding the complications of mental health problems."
Pervasiveness of work-related Musculoskeletal Disorders on Indian construction workers
International Journal of Experimental Research and Review, 2023
Indian construction involves a large number of organized and unorganized workers. There is always a risk of accidents, injuries and disability due to working in an awful, inconvenient workplace and unfavourable conditions. Construction workers work in static, dynamic and awkward postures throughout the day. The work duration, frequency of working and working technique has led to the development of Work-related musculoskeletal disorders in construction workers in India. The study was conducted to corroborate the feeling of pain in different body parts by construction workers and its association with an individual risk factor, physical risk factors and psychosocial risk factors. Information was collected from four-hundred and sixty-five workers doing various construction works. The statistical analysis (Pearson correlation and Binary Logistic Regression Analysis) was performed to confirm the feeling of pain with individual, physical and psychosocial risk factors. The result shows that there is a significant relationship between pain and working in an awkward posture, age, and years of experience. Workers are exposed to the lower back (72.90%), shoulders (49.68%), arms/hands (47.31%), wrists (30.75%), legs (26.67%), neck (24.09%), fingers/thumbs (23.23%) and knees (16.13%). The result also shows that construction workers work in stressful, painful, tedious conditions and awkward postures. For the development of musculoskeletal disorders, working in an awkward posture, year of experience, doing pervasive jobs, traumatic incidents and age are more responsible for which detailed investigation is required.

Background There is growing evidence that physical and psychosocial exposures at work increase the risk of musculoskeletal disorders. The aim of this study was to describe the distribution and co-occurrence of these risk factors in the working population. Methods We used data from the Health 2000 survey carried out in Finland in [2000][2001]. The sample of our study consisted of 2,491 men and 2,613 women who had been actively working during the year preceding the survey. Logistic regression and exploratory factor analysis were used to analyze the co-occurrence of the work-related risk factors. Results Exposure to high physical work load and several co-occurring work load factors was more prevalent among men than women. In women, as opposed to men, the highest exposure to most physical work load factors was found in their later work life. Gender and age showed weak associations with psychosocial work load factors. Low socioeconomic position, in both genders, was related to an increased risk of being exposed to several co-occurring physical or psychosocial factors. Physical exposures most frequently co-occurred with high job demands and low job control in men. Among women, physical exposures were found to co-occur with high job demands, low job control and job insecurity.

Context: The study was conducted in Chennai, India in response to increase in number of health complaints among call centre workers in an organization. Aim: To assess the relationship between work-related musculoskeletal disorders and workplace psychological stress. Settings and designs: Cross-sectional study design. Methods and materials: After obtaining informed consent, data was collected using selfreported questionnaire distributed to 155 call centre workers in the organization. Statistical analysis used: Chi-square test, t-test & general logistic regression. Results: From the worker's perception, it was found that 65.8% of the participants have average level of mental stress at work. Among the various work-related psychological stressors, things happening outside of control at work had the highest impact on most of the subjects (84.5%). The most frequent physical pain/discomfort experienced by the study participants in the previous 12-month period concerned the neck region (53.5%). Statistical analysis showed significant association between the prevalence of MSD and occupational mental stress. Conclusion: Occupational/workplace mental stress has a significant positive association with prevalence of MSD among call centre workers. A systematic approach to risk reduction addressing the organizational, psychosocial and physical work factors is required. More research is required to know about the interaction between psychological stress and MSD.
Psychosocial stressors at work and musculoskeletal problems
Scandinavian Journal of Work, Environment & Health, 1994
OBJECTIVES-This paper examines the relationship between work stressors and the following health indicators: psychosomatic complaints, health behavior, and musculoskeletal problems. METHODS-Secondary analyses were performed on data from the National Work and Living Condition Survey, which provides a representative sample of the working population in The Netherlands. The survey was made in 1977, 1983, and 1986 by The Netherlands Central Bureau of Statistics. By means of factor analysis the following three risk dimensions were identified in the survey: work pace, intellectual discretion, and physical stressors. RESULTS-High work pace, low intellectual discretion, and physical stressors were associated with increased health complaints (both psychosomatic and musculoskeletal) and musculoskeletal disorders after adjustment for gender, age, education, and sports participation. Low intellectual discretion, but not high work pace, was associated with poor general health and health behavior indicative of poor health. Physical stressors were associated with general health as well, but not with health behavior, except for reported absenteeism. CONCLUSIONS-Psychosocial stressors are not only associated with psychosomatic complaints and health indicators, but also with musculoskeletal problems, both acute and chronic. Especially the relation between intellectual discretion and musculoskeletal problems can be partly attributed to physical load. Even after adjustment for physical stressors and moderating personal characteristics, the relationships between the psychosocial stressors and musculoskeletal problems remained significant and comparable in strength to the relationship between psychosocial stressors and several other health outcomes, such as psychosomatic complaints.
