A Study on Prevalence of Musculoskeletal and Work Related Risk Factors among Fish Processing Industry Workers in Mangalore: - A Community based Survey
Keywords:Fishing, Fish industry, workers, musculoskeletal problems
Background: Fishing and fish processing in India is a major industry in coastal states. Job demand in fishing
industry involves awkward work postures, repetitive or continuous stresses on a worker’s musculoskeletal
system which makes them vulnerable for various work-related musculoskeletal disorders (WRMSDs).
Several risk factors at workplace and in the work related task have been identified to be strongly associated
with WRMSDs, however there is limited retrievable literature identifying these risk factors in people
involved fishing and fish processing industry. Objectives: To find out the prevalence and association between
WRMSD and task related ergonomic risk factors in fish processing industry. Studydesign: Cross sectional
study design. Methods: This cross sectional study was conducted among (n=83) various workers involved
in the fish processing industries along the coastal region of Southern Karnataka. NMQ which is a valid and
reliable self-administrated questionnaire commonly used to identify WMSDs was distributed among the
workers at their worksite. Subjects who had completed the NMQ with more than 90% response rate were
included for data analysis, and task analysis was done by using REBA which was evaluated through tripod
mounted motion capture camera. Results: The prevalence data in this study was collected using Nordic
musculo-skeletal questionnaire, in which it was found that musculo-skeletal issues pertaining to neck and
upper back were the most prevalent (52.9% each) in the period of past 12 months followed by lower back
(51.8%), knee (42.4%), shoulder (31.8%), elbow (20%), wrist (16.5%) , ankle (15.3%) and Hips (7.1%).
Of all the occupational categories analysed, the mean REBA score was the highest for cutting (6.88+ .32),
whereas all the other categories had an identical mean score of 6.0+0 and the difference was found to be very
highly significant. Conclusion: This study finding showed the link between adverse effects of inadequate
work conditions and musculoskeletal injuries in fishery industry.
