Association Between Risk Factors and Prevalence of Musculoskeletal Disorders Among Laboratory Professionals-an European Perspective.

Background: Musculoskeletal disorders (MSDs) are a large group of diseases that severely affect work productivity and quality of life.

Objective: To examine the differences in the prevalence of MSDs among laboratory professionals (LP) and to assess their association with individual, psychosocial, and occupational risk factors.

Methods: In a multicenter, cross-sectional study, a questionnaire was distributed online through professional association networks. Participants were divided into two groups based on their territorial affiliation-European Union (EU) and non-EU member states. Descriptive and inferential statistics were included in the analysis, and statistical significance was set at ≤0.05.

Results: A total of 640 LPs from 20 European countries participated in the study, predominantly females (78.4%) with university degree (59.4%) and mean age of 41.2 ± 10.1 years. Statistically significant differences between groups were confirmed for several variables studied: neck flexion > 15 (p = 0.008), hands at chest level (p = 0.000), longer screen time, and sitting (p = 0.000). One-third of participants reported wrist (35.6%), shoulder (32.7%), and elbow (31.6%) pain, while low back pain was more common (48.9%). A statistically significant association was confirmed between the incidence of MSDs and stress at work, repetitive movements, and prolonged standing (p = 0.000). Several variables showed significant correlations with MSDs in different body parts (p <0.05).

Conclusion: Our results show a higher prevalence of MSDs in LPs and recommend the development of targeted prevention programs and additional measures to modify the work environment and organizational activities.
