Prevalence and Awareness of Restless Leg Syndrome in Medical Students and Associated Self Reported Sleep Problems.

Objective: Restless legs syndrome (RLS) symptoms may cause stress and anxiety, which lead to functional disturbances. In several studies, awareness about RLS was found to be low in physicians and medical students who live through a rigorous educational period. In this study, we aimed to investigate the frequency, risk factors, and awareness of RLS in medical students and associated sleep problems. Materials and Methods: This cross-sectional analytical study included thirdand fourth-year medical students. A questionnaire about sociodemographic characteristics and RLS parameters, including risk factors, diagnostic criteria, awareness, and sleep problems was applied to 354 students in a period of two months. Data were evaluated using chi-square, Fisher's exact test, Kolmogorov-Smirnov test, student's t-test, and Mann-Whitney U test. Results: There were 39 participants (11.1%) who fullfilled diagnostic criteria A of RLS based on the international classification of sleep disorders 3. The female-to-male ratio was 1.6:1. Lower income and family history were associated with RLS symptoms (p=0.003, p=0.041). Self-reported symptoms of anxiety and stress as well as functional impairment were associated with RLS (p=0.003, p=0.004). Depression and sleep problems were more frequent in participants experiencing RLS symptoms (p=0.005, p=0.005). Awareness about RLS was observed in those with probable RLS (p=0.003), attending their neurology rotation did not affect awareness, and web sources were reported as the main sources about RLS-related data. Conclusion: In this study, lower income, family history, depression as a comorbidity, poor sleep quality, anxiety, stress, and daytime dysfunctionality were associated with RLS symptoms. Awareness about RLS was quite low in medical students. To enhance the diagnosis, treatment, and appropriate referrals concerning RLS, awareness should be increased in medical students.
