Abstract:
To describe the prevalence of musculoskeletal problems in the Canadian working population and to determine cross sectional associations between such problems and work factors, particularly job strain and physical demand variables.The Canadian 1994 national population health survey (NPHS) sampled 4230 working men and 4043 working women (ages 18-64) who answered an abbreviated version of the job content questionnaire. Workers were classified into four strain categories: high, passive, active, and low. Outcomes were restricted activity due to musculoskeletal disorders and the diagnosis of a back problem (both yes or no). Survey weights were incorporated to allow for different probabilities of selection. Logistic regression analyses were carried out separately for women and men, controlling for sociodemographic factors.Prevalence of chronic back problems diagnosed by a health practitioner was 14.5% among men and 12.5% among women. Men had a 6.6% prevalence of restricted activity due to musculoskeletal disorders, whereas the corresponding figure for women was 5.3%. Women, but not men, in high strain jobs were more likely to report both back problems (odds ratio (OR) 1.60, 95% confidence interval (95% CI) 1.14 to 2.28) and restricted activity (OR 1.98, 95% CI 1.16 to 3.48) compared with those in low strain jobs. High physical exertion was an independent predictor of back problems in both sexes. For both men and women, low social support at work and high job insecurity were independent predictors of restricted activity due to musculoskeletal disorders. Conversely, chronic back problems contributed to explanation of high job strain among women (OR 1.76, 95% CI 1.30 to 2.39) and high physical exertion among men (OR 1.39, 95% CI 1.09 to 1.77), whereas restricted activity due to musculoskeletal disorders contributed to explanation of high job insecurity in both sexes.Associations of interest between work stressors and musculoskeletal problems in this cross sectional study provide evidence for physical and psychosocial factors both affecting disability and being affected by disability in a working population.Keywords:

ABSTRACTIntroduction: Musculoskeletal Disorders (MSDs) is one of the health problems caused by the used equipment or performed activity while working. The workers in the packaging section of the iron and steel industry who do the packaging process manually are exposed to the risk of experiencing MSDs due to the working attitudes and non-ergonomic postures. This study aims to identify the correlation between ages, years of service, as well as working postures and the complaints of MSDs experienced by the workers of the packaging section of iron and steel industry in Sidoarjo. Methods: This study applied a cross-sectional design. The research population was all workers in the packaging section of an iron and steel industry in Sidoarjo, reaching 27 people. The research samples are the total population of the workers in the packaging section of an iron and steel industry in Sidoarjo. The risk assessment of MSDs was carried out by using the Rapid Entire Body Assessment (REBA) method, while the risk complaints were measured by using the Nordic Body Map (NBM) questionnaire. The data were tested by using Chi-Square. Results: The results revealed that there were moderate correlations between the age and the MSDs complaints (phi coefficient=0.335), between the years of service and the MSDs complaints (phi coefficient=0.433), and between the working postures and MSDs complaints (phi coefficient=0.401). Conclusion: The moderate-level of correlation still affected the occurrence of MSDs complaints. Keywords: ages, years of service, working postures, musculoskeletal disorders complaints

Introduction: Musculoskeletal Disorders (MSDs) defined as a disorder of muscles, nerves, and tendons compounded by the unergonomic working posture. Workers in Circulator Loom Unit of PT. Kerta Rajasa Raya are at risk for experiencing MSDs because of their unergonomic works. The purpose of this research was to learn more about MSDs including its related factors in Circulator Loom unit of PT. Kerja Rajasa Raya workers. Methods: this was a descriptive research which conducted using the observational method. The respondents were total population workers of Circulator Loom Unit at PT Kerta Rajasa Raya which is up to 47 workers. This research used MSDs complaint, working postures, and individual factors including age, sex, working period, physical fitness, and body mass index as the variable data. Results: 91.5% respondents were experiencing MSDs with 53.5% were in moderate severity level. Using REBA method to calculate the ergonomic risk level, it can be concluded that 23.4% of respondents have low risk of experiencing MSDs, 68.1% in medium risk, and 8.5% of respondents were having high risk of experiencing MSDs. Conclusion: working posture was the most influential factor causing MSDs with correlation coefficient score 0.629, in addition, working period, age, sex, Body Mass Index, and physical fitness were existed as supporting factors. Keywords: ergonomic, musculoskeletal disorders, working posture

Objective: The aim of this study was to characterize associations between psychosocial and work organizational risk factors and upper-extremity musculoskeletal symptoms and disorders. Background: Methodological limitations of previous studies of psychosocial and work organizational risk factors and musculoskeletal outcomes have produced inconsistent associations. Method: In this prospective epidemiologic study of 386 workers, questionnaires to assess decision latitude (“control”) and psychological job demands (“demand”) were administered to study participants and were used to classify them into job strain “quadrants.” Measures of job stress and job change were collected during each week of follow-up. Incident hand/arm and neck/shoulder symptoms and disorders were ascertained weekly. Associations between exposure measures and musculoskeletal outcomes were estimated with proportional hazard methods. Results: When compared to the low-demand/high-control job strain referent category, large increases in risk of hand/arm disorders were observed for both high-demand/high- control (hazard ratio [HR] = 4.49, 95% confidence interval [CI] = [1.23, 16.4]) and high-demand/low-control job strain categories (HR = 5.18, 95% CI = [1.39, 19.4]). Similar associations were observed for hand/arm symptoms. A strong association was also observed between the low-demand/low-control job strain category and neck/shoulder disorders (HR = 6.46, 95% CI = [1.46, 28.6]). Statistically significant associations were also observed between weekly stress level and weekly job change and several musculoskeletal outcomes. Conclusion: Associations between psychosocial risk factors and work organizational factors and musculoskeletal outcomes were large and in the hypothesized direction. Application: Prevention of occupational musculoskeletal disorders may require attention to psychosocial and work organizational factors in addition to physical factors. Methods to control adverse effects of psychosocial and work organizational risk factors should be explored.

Objectives Most previous studies of the association between psychosocial stress and musculoskeletal illness among computer users have been cross-sectional and have yielded inconsistent results. The association between a measure of psychosocial stress, “job strain”, and incident neck–shoulder and arm–hand musculoskeletal symptoms was investigated among recently hired computer users. Methods The participants worked for one of several large employers and were followed prospectively for 6 months. The “job demands” and “decision latitude” subscales of the Job Content Questionnaire were used to estimate the job-strain quadrants and a ratio measure of job strain which was subsequently categorized. Incident musculoskeletal symptoms were obtained with weekly diaries. Proportional hazards models were used to estimate associations between job strain and incident musculoskeletal symptoms. Results Those in the high-strain quadrant were at increased risk of neck–shoulder symptoms [hazard ratio (HR) 1.65, 95% confidence interval (95% CI) 0.91–2.99] when compared with those in the low-strain quadrant. Those in the highest strain-ratio category were also at increased risk of neck–shoulder symptoms when compared with those in the lowest strain-ratio category (HR 1.52, 95% CI 0.88–2.62). Modification by previous years of computer use was observed, with an elevated risk observed for those in the highest job-strain ratio category who also had low previous computer use (HR 3.16, 95% CI 1.25–8.00). There did not appear to be an association between either measure of job strain and incident arm–hand symptoms. Conclusions In this cohort, workers who reported high job strain were more likely to develop neck–shoulder symptoms.

Aim of this study was to determine the prevalence of work-related musculoskeletal disorders among cameramen. They frequently experience physically demanding tasks such as working in uncomfortable postures, engaging in repetitive manual tasks and enduring long working hours. To assess pain sites Nordic Musculoskeletal Questionnaire was used among a total of 100 cameramen aged between 30-50. 86 of which reported Musculoskeletal pain/ discomfort. Notably, 47 individuals fell within the age group of 30-40 while the remaining 39 belonged to the age group 41-50. The findings concluded high occurrence of work-related musculoskeletal disorders among the population with the most affected regions being the lower back followed by the shoulder and the neck.
