Abstract

|
|
Objectives: The aim of this study was to determine the prevalence of symptoms relating to musculoskeletal disorders(MSDs) and investigate the risk factors among researchers at university laboratories.
Methods: 209 researchers were included in this study, drawn from 27 laboratories at three universities in Korea. Checklists for MSD symptoms and risk factor assessment were utilized.
Results: The symptoms checklist showed reliable results with Cohen’s Kappa 0.33-0.56, percent agreement 81.0-96.8%, and correlation coefficient 0.41-0.63. The overall prevalence of MSD symptoms was 68.9%, while the prevalence in specific parts of body were as follows: shoulders(47.6%), lower back(46.9%), neck(46.9%), knees(25.4%), wrists(20.1%), elbows(13.6%). The symptom prevalence among women was higher than among men(OR 2.67, 95% CI 1.37-5.18). Daily exposure time was observed to be a significant risk factor for developing MSD symptoms(OR 2.14-6.07).
Conclusions: This study suggested that repetitive pipetting and static work posture are the most significant risk factors for MSD symptoms among laboratory researchers.
