Biopsychosocial factors and perceived disability in saleswomen with concurrent low back pain.

OBJECTIVES: To quantify disability level in salespeople with concurrent low back pain (LBP) and to determine the relative associations between demographic, occupational, psychosocial and clinical factors and back disability. LBP is the most common cause of work-related disability in people under 45 years of age and the most expensive cause of work-related disability, in terms of workers' compensation and medical expenses. Evidence suggests high prevalence of LBP in salespeople. METHODS: A cross-sectional survey was conducted in which 184 saleswomen with a current episode of self-reported LBP working in a large up-scale department store filled out a battery of 6 self-administered questionnaires and received a standardised physical examination. RESULTS: Saleswomen with concurrent LBP had low disability levels. Factors significantly associated with disability were pain intensity, measured by a visual analogue scale, in the past week (p < 0.001), physical and mental health status (p < 0.001, p = 0.003, respectively), fear avoidance scores for both work and physical activities (p = 0.031, p = 0.014, respectively), past history of LBP (p = 0.019), and self-reported frequency of pushing or pulling objects placed in high positions during work (p = 0.047). A significant level (45%) of the variance in disability status was explained by these variables. CONCLUSION: In clinical management of LBP workers who required prolonged standing, such as salespeople, clinicians should look for modifiable risk factors associated with disability. Specific measures need to be taken to prevent disability due to LBP among salespeople.

The relationship between upper extremity musculoskeletal symptoms attributed to work and risk factors in office workers.

PURPOSE: Office workers are exposed to various individual, work-related and psychosocial factors during work that have been associated with the development of musculoskeletal symptoms. There is an increasing in evidence that suggests that musculoskeletal symptoms in the upper extremity are very common among office workers. The aim of this study was to examine the effects of individual, work-related physical and psychosocial factors on the prevalence of shoulder, elbow and wrist/hand symptoms attributed to work in office workers. METHODS: A self-administered questionnaire was delivered to 2,000 office workers in 54 workplaces in Bangkok, registered at the Social Security Office of Thailand. RESULTS: A total of 1,428 subjects (71%) returned the questionnaire, of whom 1,185 were eligible for the study. Alcohol consumption, frequency of working in an uncomfortable posture and relationships with colleagues were each significantly related to the prevalence of experiencing shoulder symptoms. No significant association between the investigated factors and the prevalence of experiencing elbow symptoms was found. Frequency of working in the position that hands were above the shoulder level and self-rated perception of air circulation in the office were significantly associated with the prevalence of experiencing wrist/hand symptoms. CONCLUSIONS: Various individual, work-related and psychosocial factors were identified to be associated with high prevalence of musculoskeletal symptoms attributed to work in the shoulder and wrist/hand among office workers. Further research investigating the causal relation between these factors and musculoskeletal symptoms should be conducted.

Biopsychosocial factors are associated with high prevalence of self-reported musculoskeletal symptoms in the lower extremities among office workers.

BACKGROUND AND AIMS: Little attention has been given to musculoskeletal symptoms in the lower extremities among office workers. The aim of this study was to investigate the relationships between the self-reported prevalence of musculoskeletal symptoms in the hip, knee and ankle/foot and individual, work-related physical and psychosocial factors. METHODS: A cross-sectional survey was conducted in which 2000 office workers from 54 workplaces in Bangkok registered at the Social Security Office of Thailand received a self-administered questionnaire. Of those, 1428 (71%) returned the questionnaire. After screening for exclusion criteria, 1185 office workers were eligible for the study. The prevalence of self-reported musculoskeletal symptoms in the hip, knee and ankle/foot was associated with certain individual, work-related physical and psychosocial factors. RESULTS: Mental demands and work repetitiveness were each significantly associated with the prevalence of experiencing hip symptoms. Suffering from a chronic disease, the average number of working hours/day, sleep quality and self-rated perception of air circulation in the office were significantly related to the prevalence of experiencing knee symptoms. Significant associations were found between the prevalence of experiencing ankle/foot symptoms and sleep quality, self-rated perception of the ergonomics of the desk and size of office space and frequency of feeling frustrated during the previous 4 weeks. CONCLUSIONS: Results of this study indicated that several biopsychosocial factors were associated with a high prevalence of self-reported musculoskeletal symptoms in the lower extremities among office workers. Further prospective studies are required to substantiate the observed associations.

Associations between prevalence of self-reported musculoskeletal symptoms of the spine and biopsychosocial factors among office workers.

OBJECTIVES: To investigate the relationships between the self-reported prevalence of musculoskeletal symptoms in the neck, upper back and low back and certain individual, work-related physical and psychosocial factors. METHODS: We conducted a cross-sectional survey using a descriptive questionnaire, which was distributed to 2000 office workers in 54 workplaces, in Bangkok, registered at the Social Security Office of Thailand. RESULTS: Returns were 1,428 (71%) questionnaires, and after screening for exclusion criteria, 1,185 office workers were found to be eligible for the study. For the head/neck region, frequently working in an uncomfortable posture increased the risk of experiencing head/neck symptoms (adjusted OR=1.81, 95% CI=1.35-2.44). For the upper back region, frequent trunk bending during work increased the risk of experiencing upper back symptoms (adjusted OR=1.80, 95% CI=1.32-2.44) whereas working in a job that required little interaction with others decreased the risk of experiencing upper back symptoms (adjusted OR=0.42, 95% CI=0.25-0.68). For the low back region, working for >8 h a day showed an elevated risk for low back symptoms (adjusted OR=1.66, 95% CI=1.25-2.22). CONCLUSIONS: Some biopsychosocial factors were associated with the prevalence of musculoskeletal symptoms in the spine among office workers. Further research should focus on these factors in order to develop specific strategies to reduce the occurrence of such symptoms in the office environment.

Prevalence of self-reported musculoskeletal symptoms among office workers.

BACKGROUND: To date, no study has investigated the prevalence of self-reported musculoskeletal symptoms in all the body regions in the general population of office workers. AIMS: To estimate the 12-month prevalence of self-reported musculoskeletal symptoms in the head/neck, shoulders, elbows, wrists/hands, upper back, low back, hips, knees and ankles/feet among office workers. METHODS: We conducted a cross-sectional survey using a descriptive questionnaire distributed to 2000 office workers in 54 workplaces. RESULTS: A total of 1428 subjects (71%) returned the questionnaire, of whom 1185 were eligible for the study. The annual prevalence of self-reported musculoskeletal symptoms attributed to work was 63%. Sites of symptoms, in order of prevalence, were head/neck (42%), low back (34%), upper back (28%), wrists/hands (20%), shoulders (16%), ankles/feet (13%), knees (12%), hips (6%) and elbows (5%). Female office workers were more likely to report symptoms in the head/neck, shoulder, upper back and ankle/foot regions than male counterparts (P < 0.05). Office workers younger than 30 years were more likely to have symptoms in the upper back than those older than 49 years (P < 0.05). CONCLUSION: Musculoskeletal symptoms are common among office workers with a high proportion experiencing symptoms in the spine. The prevalence of musculoskeletal symptoms in some body regions is dependent on gender and age. This indicates a need to develop specific strategies to reduce the occurrence of such symptoms among office workers.
