Prevalence of laboratory-related musculoskeletal disorders among biomedical scientists

Abstract

BACKGROUND: Laboratory- related musculoskeletal disorders (LMSDs) are injuries resulting from working in the laboratory. Biomedical scientists (BMSs) play an important role in any health care system. However, they are at high risk of exposure to the LMSDs. OBJECTIVE: This study aimed to estimate the prevalence and the associated risk factors of LMSDs among this group of healthcare professionals. METHODS: We conducted a cross-sectional survey using the Nordic Musculoskeletal Questionnaire to estimate the prevalence of the LMSDs among the BMSs. BMSs with occupational or non-occupational accidents that affected their musculoskeletal system were excluded from the study. A Chi-square test was performed to measure the significant association between different risk factors (age, gender, weight, height, nationality, specialty, educational level, nature of the job, and the number of experience years) and the prevalence of the LMSDs among the BMSs. RESULTS: The study included 83 BMSs. Females represented 63.9% and 36.1% were in the age group of 35- 44. The overall prevalence of the LMSDs was 77.1%. The most prevalent LMSDs were neck, shoulders, and lower back with 50.6%, 49.4%, and 43.4%, respectively. A total of 65.57% of BMSs had irregular symptoms of LMSDs. CONCLUSION: The study found that the prevalence of LMSDs among the BMSs was high. Good practice and training in ergonomics may minimize the prevalence of LMSDs among the BMSs.
