Low back pain and musculoskeletal symptoms among Kansas farmers

BACKGROUND: Farming continues to rank as one of the most dangerous occupations in the United States. The purpose of this study was to determine the prevalence of low back pain and other musculoskeletal disorders (MSDs) among the farmers and to examine the factors associated with occupational back pain. Farmers in a predominately corn and soybean growing region of Kansas served as the study sample. METHODS: Questionnaires were mailed out to 499 active farmers of a Farmers' Cooperative in Southeast Kansas. The self-administered questionnaire was used to determine the prevalence of self-reported symptoms of back pain and other MSDs and to determine the strength of associations between back pain and work factors. RESULTS: The participation rate was 57.2%. The low back was the anatomical area with the highest prevalence of self-reported work-related pain (37.5%), followed by the shoulders (25.9%), knees (23.6%), and neck (22.4%). Close to 60% of the farmers reported that they experienced farm work-related MSD symptoms in at least one of the nine body areas in the previous year. Nearly one quarter of the farmers reported seeing a physician for their low back symptoms, and one in five farmers had to modify their work habits due to low back symptoms during the previous year. CONCLUSIONS: Low back pain and other musculoskeletal conditions are a significant problem for Kansas farmers. This group of Kansas farmers experienced low back pain at a much higher rate than the general working population and higher than other groups of farmers previously studied.

Musculoskeletal discomfort of music teachers: an eight-year perspective and psychosocial work factors

Musicians at all levels of performance, especially string players, are known to have a high prevalence of work-related musculoskeletal disorders. The disorders seem to be most common in the neck, shoulders and low back. In 1988, a survey of the work-related musculoskeletal disorders of 36 music teachers was carried out at a music school in northern Sweden. In 1996, the teachers were reinvestigated. The study also included an investigation of the psychosocial work environment according to the Karasek demand-control theory, as well as measurements of upper-arm elevation during a working day in five violin teachers. The results showed that music teachers, like other professional musicians, often experience discomfort in the neck, shoulders, and low back. The discomfort tended to be of long duration, increasing over the years. The psychosocial work environment was characterized by high psychological demands and low authority over decisions. This was compensated for through good social support. The work required skill and creativity but was monotonous. The measurements of upper-arm elevation indicated considerable variations in shoulder positions between teachers. There were also differences in the work done with the right and left arms, with repetitive motions more commonly involving the right arm. Approximately a fourth of the working day was spent with the arm elevated 30-90 degrees. The relationships between upper-arm movements and ratings of discomfort were moderate.     

Musculoskeletal complaints among Italian X-ray technologists

The aim of this study was to determine the prevalence of musculoskeletal complaints among X-ray technologists and to examine their relationship with physical and psychosocial factors. A cross-sectional study was performed in 2006 among 203 X-ray technologists working in 13 hospitals in the Apulia region of southern Italy. A questionnaire was used to collect data on personal characteristics, physical workload, psychosocial aspects, and the presence of musculoskeletal symptoms in the neck, shoulders, low back, hand/wrist and legs. Univariate analyses and multiple logistic regression analyses were then performed. The prevalence of complaints at any body site in the previous 12 months was 67%. Low back pain was the most commonly reported symptom (59.6%), followed by shoulder (21.2%), neck (19.7%), leg (13.8%) and hand/wrist pain (12.3%). Age was associated with low back pain, while high physical workload was associated with symptoms in the neck, low back and hand/wrist. High job demands were associated with neck and shoulder pain. Overall, our study suggests high prevalence rates of musculoskeletal complaints may exist among Italian X-ray technologists. Physical workload, psychosocial and individual factors appear to be important risk factors for musculoskeletal disorders within this occupational group.

Association of risk factors with musculoskeletal disorders in manual-working farmers

The current study is aimed at recognizing the risk factors for major work-related issues (ie, musculoskeletal disorders [MSDs]) among 138 manual-working farmers. Data were collected using modified Standardized Nordic Questionnaire and the Rapid Upper Limb Assessment score sheet. Different factors influencing MSDs were detected using logistic regression methods. The highest occurrence rate for MSDs was observed in the lower back (71.4%), followed by fingers (62.1%), shoulders (56.4%), and hands/wrists (55%). Factors such as age, gender, daily working hours, hand dominance, perceived fatigue, and work experience were found to be associated with MSDs in one or more upper body regions. The outcome of multinomial regression showed that gender is the most influencing factor for MSDs in all upper body regions except the shoulders. The outcomes of study indicate high occurrence of MSDs among manual-working farmers and highlight the significance of individual and work-related factors.

  结论  办公室文员职业性肌肉骨骼疾病的患病率较高，患病部位最高的是颈部，其次是肩部、腰部；工作中人体保持各种不良姿势均会增加身体各关节肌肉骨骼的负担，造成肌肉骨骼损伤。应该采取相应的干预措施，降低办公室文员职业性肌肉骨骼疾病的患病率。
     

Work-related musculoskeletal disorders in Norway's offshore petroleum industry

BACKGROUND: Since 1992, physicians have reported work-related diseases among workers in Norway's offshore petroleum industry to the Petroleum Safety Authority, as required by law. AIMS: To analyse the number of reported work-related musculoskeletal disorders and risk factors (occupation and reported exposure) from 1992 to 2003. METHODS: Data from the Petroleum Safety Authority's registry of work-related diseases were analysed. RESULTS: During the 12 years, 3131 new work-related musculoskeletal disorders were reported and this was the category of work-related disease most frequently reported (47%). The number of work-related musculoskeletal disorders varied substantially from year to year. Disorders of the upper limb accounted for 53% and back disorders for 20% of all work-related musculoskeletal disorders. Lower limb disorders accounted for 16%, of which knee disorders dominated (12% of all cases). The dominant occupational categories were maintenance work (40%) and catering (21%). Frequently reported types of exposure were high physical workload, repetitive work and walking on hard surfaces/climbing stairs and ladders. CONCLUSION: Strategies for preventing musculoskeletal disorders should be carried out to reduce the burden of high physical workload and repetitive work, especially in maintenance work and catering. Further research is recommended on the association between walking on hard surfaces/climbing stairs and ladders and knee disorders. Reporting routines need to be improved to monitor trends over time and to assess the effects of interventions.     

Musculoskeletal symptom survey among mason tenders

BACKGROUND: Low back pain (LBP) constitutes a major problem in construction. The magnitude and musculoskeletal injury characteristics in certain construction trades have been studied extensively. Musculoskeletal research targeting mason tenders is limited. High physical demands of the job primarily contribute to an increased risk of LBP experienced by these laborers. METHODS: A symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the mason tenders, and to identify work-related activities perceived by them as contributing to their disorders. RESULTS: The findings revealed that 82% of the mason tenders experienced at least one musculoskeletal symptom in the last year. LBP was the most frequently reported symptom (65%). Due to LBP, 12% of the laborers missed work and 18% of them visited a physician. Bending or twisting the back, working in the same position or in pain, and heavy lifting they perceived as the most problematic work-related activities. The vast majority of the laborers requested job-safety training. CONCLUSIONS: The mason tenders experienced high prevalence of LBP. To address the problem a model for primary prevention of LBP was developed and implemented in the trade. The model incorporated ergonomic principles, hazard recognition, and problem solving in the training curriculum for the union instructors teaching apprentices the trade-specific skills.

Relationship between musculoskeletal disorders and work-related awkward postures among a group of health care workers in a hospital

BACKGROUND: There are few studies in the Italian literature on musculoskeletal disorders (MSD) among health care workers (HCW) keeping and holding awkward postures during their job. OBJECTIVES: The aims of this study were to determine the prevalence of low-back, neck and upper limb complaints and the association between risk factors and MSD in HCW working in 15 wards of the Hospital of Cuneo. METHODS: A questionnaire was submitted to 113 HCW. Information about demographic and occupational factors, and MSD characteristics were collected to be statistically elaborated. RESULTS: The prevalence of complaints regarding at least one of the 3 body regions was 71% in the whole sample (80 subjects). Low back, neck and upper limb were interested, respectively, in 58.4%, 50.4% and 25.7% of the cases. Logistic regression showed a significant association of MSD with score > 7 on the Borg scale (OR = 9.70; CI: 2.01-46.9; p < 0.01), positive musculoskeletal clinical history (OR = 3.67; CI: 1.24-10.88; p < 0.05), and visual defects (OR = 2.88; CI: 1.07-7.81; p < 0.05). Based on the answers from the questionnaire, the onset of MSD was attributed in 41 cases to organizational problems, and in 14 cases to the ergonomic characteristics of the job. CONCLUSIONS: The index of prevalence of MSD associated to work-related awkward postures (71%) is very high, greater than that observed among HCW exposed to manual lifting of weights (21%) in the hospital. Thereafter, assessment of exposure and containment of such occupational risk must be considered useful.     

Prevalence of musculoskeletal pain and associated factors in the Quebec working population

Background: While the determinants of musculoskeletal pain are numerous, few studies conducted among workers have taken into account, altogether, physical factors, psychosocial factors (personal and work-related) and individual characteristics. Objectives: To estimate the 1-year prevalence of musculoskeletal pain in the Quebec working population by gender and anatomical site, and to determine which factors are associated with these prevalence figures. Methods: Data came from the 1998 Quebec Health Survey and included 9,496 individuals. One-year period prevalences for neck pain, back pain and pain in the upper and lower extremities were calculated for men and women. Logistic regression analyses were conducted to estimate the associations between individual, physical and psychosocial work factors, on one hand, and musculoskeletal pain in the four body regions, on the other hand. Results: For both genders back pain was the most frequent musculoskeletal symptom that had disturbed their activities during the past year. The largest difference between genders was observed for neck pain (women: 18%; men: 11%). Multivariate analyses indicated that physical and psychosocial work factors, as well as psychological variables, were associated with musculoskeletal pain in different body regions. Body mass index was associated only with pain in lower extremities for both genders. Conclusions: The results of this study suggest that interventions aimed at reducing musculoskeletal pain should take into account personal and work-related psychosocial variables, in addition to physical workload.     

Symptoms of musculoskeletal disorders among apprentice construction workers

Musculoskeletal disorders (MSDs) are a major cause of work-related disability and lost-time illnesses for many occupational groups. This study determined the prevalence of musculoskeletal symptoms among young construction workers. A symptom and job factors survey was self-administered to 996 construction apprentices. Prevalence was determined by the percent of positive responses to musculoskeletal symptom questions. Odds ratios and 95 percent confidence intervals were the measures of association between prevalent musculoskeletal symptoms and demographic, leisure, and job factors and were determined by logistic regression. The low back was the site most commonly reported for job-related musculoskeletal symptoms (54.4%), which was also the most common reason for seeking care from a physician (16.8%) and missing work (7.3%). Number of years worked in the construction trade was significantly associated with knee (p-trend = 0.0009) and wrist/hand (p-trend < 0.04) MSD symptoms and was suggestive of an association with low back pain (p-trend = 0.05). "Working in the same position for long periods" was the job factor identified as most problematic, with 49.7 percent of all construction apprentices rating it as a moderate/major problem contributing to musculoskeletal symptoms. Musculoskeletal symptoms are a significant problem among young construction workers at the beginning of their careers. Prevention strategies are needed early in the apprentice training program to reduce the potential disability associated with work-related musculoskeletal symptom disorders.     

Prevalence of musculoskeletal disorders among plastics industry workers

The prevalence of musculoskeletal disorders among workers in the plastics industry in Salvador, Bahia State, Brazil was estimated. Cases were defined by reported symptoms of pain in the previous 12 months, lasting more than a week or having monthly minimum frequency, which had given rise to restrictions at work or to seeking medical attention, or where respondents had a severity score greater than or equal to 3 (on a numerical scale of 0 to 5). A stratified proportional random sample of 577 workers was studied. The prevalence of musculoskeletal disorders, considering of all body segments, was 50.1%. The prevalence of musculoskeletal disorders was higher among women than among men at distal upper extremities (34.6% and 11.6% respectively) and also in the region of the neck, shoulder or upper part of the back (27.4% and 17.6% respectively). There was no difference between genders for the prevalence of lower back pain (21.2% and 21.4% respectively); 65% of cases in this region had reports of pain in the previous seven days. Due to the importance and prevalence of musculoskeletal disorders, it is necessary that their measurement in epidemiological studies be done properly.     

Work-Related Musculoskeletal Symptoms among Loggers in the Ark-La-Tex Region

ABSTRACT

Background: The U.S. logging sector is among the most dangerous industrial sectors, with high fatality and non-fatal injury rates. Limited research has addressed work-related musculoskeletal disorders among logging machine operators (LMOs). The purpose of this study was to estimate the 12-month prevalence of musculoskeletal symptoms and the associated work-related risk factors among LMOs in the Arkansas, Louisiana, and Texas (Ark-La-Tex) logging region.

Methods: A self-administered 93-item questionnaire with six different sections: (1) demographics, (2) lifestyle and medical background, (3) work experience, (4) job training, (5) occupational heat-related stress, and (6) occupational injuries and MSS was administered to LMOs (n = 88) using Qualtrics Mobile Survey Software®. Poisson regression models were used to estimate crude prevalence ratios (PR), adjusted PR [aPR], and corresponding 95% confidence intervals (95% CI).

Results: Regarding organizational, ergonomic, and handling equipment occupational factors and 12-month MSS prevalence, the adjusted model controlled for age, BMI, smoking status, and drinking status. For organizational, the most problematic factors for the lower back were performing a task over and over (63.2%) and working very fast, for short periods (60.0%). For ergonomics, the most problematic factor for the lower extremities was awkward or cramped conditions (58.1%) and for the lower back was bending/twisting back awkward (55.9%). Last, for handling equipment, the most problematic for both the lower back and lower extremities was handling or grasping small objects (57.1%).

Conclusion: Our findings revealed associations between work-related MSS and specific job factors (e.g., organizational, ergonomic, handling equipment, etc.), extreme environmental conditions or environmental, and personal risk factors. In particular, study findings suggest lower back and lower extremities MSS are associated with the a majority of job-related risk factors, lower extremities with extreme environmental conditions, and neck and upper back with personal risk factors.     

Prevalence of musculoskeletal symptoms and associated factors among metal industry workers in Canoas--RS

Workers health is a field of community health that has opened spaces for identifying and preventing work-related diseases, especially musculoskeletal disorders in view of their extent and magnitude. We conducted thus a cross-sectional study in the biggest metal industry in the city of Canoas--RS, aimed at identifying the musculoskeletal symptoms of a group of metal industry workers and the association of these symptoms with socio-demographic and occupational variables. Two questionnaires were employed for gathering data: the first one was used to collect information on demographic and occupational variables and individual life habits and the second for identifying the prevalence of musculoskeletal symptoms (Nordic Musculoskeletal Questionnaire). Results showed that 75.2 % of the workers had related some kind of musculoskeletal symptom during the last 12 months, 53.3% during the last 7 days and 38.5% had already taken a time off due to this problem. There was also an association between the musculoskeletal symptom and the variables sex, age, occupation and educational level. We conclude that there is a high prevalence of work-related musculoskeletal disorders among workers, calling for preventive actions and health promotion in the work environment.
