The aim was to describe the profile of workers with occupational multi-site musculoskeletal disorders (MSMSD) and study the relationship between these lesions and socio-professional factors. This is a cross-sectional study involving 254 subjects with occupational musculoskeletal disorders (MSD), identified in the Department of Occupational Medicine at the University Hospital of Mahdia, in Tunisia, over a period of 10 years from 2005 to 2014. The study population was subdivided into two groups; mono-site MSD and multi-site (≥2 sites) groups. Data collection was based on a questionnaire prepared beforehand and covered the description of sociodemographic and professional characteristics. To study psychosocial constraints at work, we have used the Karasek questionnaire. MS-MSD was correlated to the number of dependent children (p=0.02), job/place of work (p=0.00), qualification (p=0.02), taking a rest period (p=0.03), decision latitude (p=0.00), mental demands (p=0.002), social support (p=0.00) and job stress (p=0.04). After binary logistic regression, MS-MSD depended significantly on the number of dependent children (p=0.013; OR=0,33; IC=0,17-0,83), working spouse (p=0.05; OR=0.35; IC=0.12-0.99), job/place of work (p=0.00; OR=4.16; IC=1.95-8.88), qualification (p=0.008; OR=0.28; IC=0.11-0.72), taking a break during work (p=0.04; OR=3.10; IC=1.04-9.22) and social support (p=0.00; OR=7,1; IC=1,9-25,3). When individual risk factors are fixed, the prevention of MS-MSD must target modifiable levers, related to the professional environment of the employees.
