ork-related musculoskeletal disorders (WMSDs) are

major causes of disability in the workplace. It is unclear

whether the exposure to risk factors and types of work play

an important role in the occurrence of WMSDs. To determine

the relationship between the prevalence of WMSDs and

exposure level of risk factors among employees from different

types of work, a cross-sectional study was performed among

shipbuilding employees. 801 randomly selected shipbuilding

workers from 6 major types of work with at least one year of

work experience at a shipyard were studied. The prevalence

and working condition data were collected using a self-

designed ergonomics questionnaire modified based on Nordic

musculoskeletal questionnaire (NMQ), and the exposure level

was determined by standard quick exposure check (QEC)

in Chinese version. WMSD positive cases were identified

according to the definition employed by National Institute for

Occupational Safety and Health (NIOSH). It was found that

both WMSD prevalence and exposure levels at various body

regions among shipbuilding workers were very high. This could

be attributable to the awkward and prolonged bending postures

adopted in the manufacturing processes. It was found that

WMSD positive workers got higher QEC scores and identified

as higher exposure levels compared with WMSD negative

workers, and a weak correlation between WMSD prevalence

and QEC score as well as that between WMSD prevalence and

exposure levels were exist at back, shoulder/arm and wrist/

hand. Both the prevalence of WMSDs and the exposure levels

varied among workers of different type of works. In conclusion,

there was a high WMSD prevalence and serious exposure

risks at various body regions among shipbuilding workers. It

seems that a higher exposure risk would lead to an increase

in the prevalence of WMSD slightly. And there were exposure

distribution differences between workers from six major types

of work in the same shipyard.
