Abstract
The seafood processing industry has been developing and providing
marked contribution to Vietnam’s economic growth in recent years. However, information on
working conditions and their impacts to workers’ health in this sector, focusing on musculoskeletal
problems in female workers, has been poorly documented. Objectives: This paper examines the
prevalence of after-shift musculoskeletal disorder symptoms (A-MSDS) and work-related factors in
female workers in a seafood processing factory in Vietnam. Materials and Methods: As part of a
comprehensive study, a cross-sectional survey was implemented in one seafood processing factory
in the center of Vietnam in 2014. A self-administered questionnaire was completed by 394 female
workers to collect information about their A-MSDS state, demographic characteristics, health status
and work conditions. Descriptive analysis and logistic regression were applied to describe and
analyse the results. Results: Nearly four-fifths of female workers experienced MSDs in at least one
body part (77.7%) and 20.1% of them had MSDs in all investigated regions. The prevalence of
A-MSDS in different body parts markedly varied, with the proportion of pain in the hips and lower
extremities being as high as 53.3%, followed by pain in the shoulders and upper extremities (42.6%)

and the neck (41.1%). A humid working environment, exposure to vibration and chemicals as well
as taxing task demands and work organizations were found to significantly contribute to the
increased risk of after-shift musculoskeletal disorders in female workers. Conclusion:
Approximately 80% of female workers in the seafood processing factory experienced
musculoskeletal pains after work, especially in the hips, extremities, neck and shoulders which were
contributed by work conditions and task demands.
