P-113 Work-Related Musculoskeletal Disorders: Experience at a Tunisian University Hospital Center

Abstract Introduction Work-related musculoskeletal disorders (MSDs) are a major public health issue due to their frequency and the economic burden they generate. The aim of our work was to study the socio-professional and clinical characteristics of work-related MSDs. Methods Retrospective descriptive study of work-related MSD cases collected in the occupational pathology department of Charles Nicolle Hospital in Tunis over a three-year period. Results A total of 80 cases of MSDs were recorded. The average age was 45.2 ± 8.3 years with a predominance of women (sex ratio (M/F) = 0.2). The average professional seniority was 19.3± 8.9 years. A history of diabetes and hypothyroidism was found in 12.5% and 5.3% respectively. Mean body mass index was 29.05±4.75 Kg/m2. Obesity was found in 35% of cases. The sectors of activity with the highest incidence of MSDs were textile manufacturing (25%) followed by the automotive industry (17.5%). The occupational category most concerned was manual workers (80%), 35% of whom were stitchers. MSDs were mainly represented by carpal tunnel syndrome (48.7%), followed by shoulder tendinopathy (42.5%). Fifteen (18.3%) employees had more than one MSD declared as work-related. A significant association was noted between the number of MSDs declared and history of diabetes (p0.05). Discussion In Tunisia, MSDs declared as occupational pathologies are on continual increase. Our study identified the textile sector as the main source of these diseases. Biomechanical constraints as well as performance requirements could explain the results found. Conclusion MSDs are multifactorial pathologies with an occupational component. Rapid implementation of ergonomic and organizational preventive measures is essential.
