Abstract:
Objective - （ ）
To analyze the occurrence pattern of work related musculoskeletal disorders WMSDs among workers
Methods
in a shipyard based on latent category model. A total of 446 workers from a shipyard in Guangdong Province were
selected as the research subjects using convenience sampling method. The prevalence of WMSDs in the past year was
，
investigated using China Musculoskeletal Questionnaire and the occurrence patterns of WMSDs were analyzed by latent class.
Results （ ）
The prevalence of WMSDs in the past year was 71.1% 317/446 . The prevalence of WMSDs in single site was 24.4%

109/446 and was 46.6% 208/446 in multiple sites. The prevalence of WMSDs in multiple sites was 3.9 17.3 times higher
than that in single site. The fitting results of latent class model showed that the model with three latent classes was the best

model. The three potential categories of WMSDs occurrence patterns in the study subjects were the all site group 28 patients

the neck and lower back/waistgroup 153 patients and the few or no site group 265 patients accounting for 6.3% 34.3%
， Conclusion
and 59.4% respectively. WMSDs of shipyard workers have obvious category characteristics. Latent class analysis
can be used to explore the occurrence pattern of WMSDs in shipyard workers.
