Restless leg syndrome (RLS) is a neurological disorder characterized by unpleasant sensations in the legs urging the affected subject to move, which negatively affects sleep and quality of life. This is a descriptive and cross-sectional study, to investigate the prevalence of RLS in patients and their relatives who come for consultation at the outpatient center of the University Hospital of Fez. We also studied the specific risk factors of RLS, its severity and its impact sleep quality of the study population. 23 subjects out of the 500 included in the study met the definition of RLS with a prevalence of 4.6%. The mean age was 46.5 years (±13.365); 11 patients (47.9%) had a very severe form, 10 patients (43.7%) had a severe form and only 2 patients (8.7%) had a mild RLS. These results showed that the prevalence of RLS is lower than what is reported elsewhere in the world. However, it confirms the results found by the only two African studies on RLS. The analysis of RLS risk factors did not show any significance between the RLS+ group and the RLS- group apart from the existence of sleep disorders. Despite limited collected data on the RLS in the African continent, it seems that, indeed, prevalence among African populations is lower comparing to West European and North American populations… Lire l’article intégral
