A cross sectional study on work related musculoskeletal disorders among software professionals.

Background: This study has been carried out to determine the prevalence and pattern of Musculo Skeletal Disorders (MSD) among software professionals and to evaluate the association between socio-demographic factors, computer work related factors and MSD. Methods: The study design was cross sectional with software professionals working in information technology (IT) companies in Chennai, Tamilnadu as the study population. The sampling method used for the survey is the non-probabilistic purposive sampling. Data was collected using a questionnaire which includes personal data, job details and standardized Nordic questionnaire. Results: Prevalence of work related MSD during last 12 months, during last 7 days and annual disability were 69%, 49.2% and 16.6% respectively. The common prevalence of work related MSD reported during last 12 months based on their body region were neck (29.56%), lower back (22.89%), shoulders (12.17%) and knees (9.56%). There was a statistically significant difference in terms of gender, regular exercise, more than 5 working days per week, more than eight hours of work per day and habit of taking lesser breaks during work hours at regular intervals. There were no statistically significant difference in terms of age, BMI and years of employment. Conclusions: The study has concluded that MSD is widely reported among software professionals working in the IT field in India. Hence, an appropriate prevention strategy needs to be carried out in order to enable them work comfortably.

Risk Factors for Absenteeism due to Work related Musculo-skeletal Disorders among Korean Employees / 대한산업의학회지

OBJECTIVES: Absenteeism due to musculo-skeletal disorders (MSDs) of workers is an important index of occupational health. Since research on its causes is rare in Korea, the risk factors for absenteeism due to MSDs should be studied. METHODS: Using the 2nd Korean working condition survey data, we investigated the prevalence of absenteeism due to MSDs. We also analyzed the risk factors for absenteeism by multiple logistic regression analysis in Korean employees. RESULTS: Prevalence of absenteeism due to MSDs was 0.7% in all employees, 0.5% in men, and 0.9% in women. In logistic regression analysis, gender, age, presence of a representative worker organization, working on tight deadlines, and pace of work dependent on automated equipment/machine were risk factors of absenteeism due to MSDs for both sexes. For males, working time, working at a very high speed were additional risk factors. For females, pace of work dependent on numerical production, performance, and targets were additional risk factors. Although not included in the multiple logistic regression analysis, handling heavy loads in both sexes and average monthly income for women were risk factors in the univariate analysis. CONCLUSIONS: For absenteeism due to MSDs, the presence of a representative worker organization, along with work pace and its determinants were important risk factors.

Investigation on musculo-skeletal disorders in tea-workers

The results of the cross-sectional study on musculo-skeletal disorders in 125 tea-workers showed that the percentage of musculo-skeletal complaints was very high (98.4%). The most common parts affected by pain were: low back (90.4%), shoulders (55.2 - 57.6%), knees (53.6 - 56.0%), hands (45.6 - 48.0%), and wrists (31.2 - 34.4%). High frequency of operation, poor postures in some jobs as well as long working time influenced on musculo-skeletal disorders. The relation between seriousness of the disorders and the level of musculo-skeletal complaints was remarkable. Some recommendations were suggested aiming at reducing the adverse effects of occupational factors
