Like migraine, RLS prevalence in Asian populations was reported to be somewhat lower than that observed in Western populations [15, 24]. The wide range of RLS prevalence values reported in previous studies may be explained by differences in ethnicity, cultural background, survey methods, and assessment tools. Similar to previous epidemiological studies for RLS, the prevalence increased with age in the present study. The similarities in the prevalence of migraine and RLS between previous studies and the present study suggest that our study properly reflects the actual prevalence of each in the Korean population."}
