Prevalence of restless legs syndrome: a community-based study from Argentina.

Background And Purpose: The number of restless legs syndrome (RLS) prevalence studies performed outside Europe and North America remains small. We conducted a community-based study to estimate the relative prevalence of RLS in Argentina.

Patients And Methods: A total sample of 471 participants from high (Buenos Aires) and low population density areas (three cities with <35,000 inhabitants), completed a self-assessment questionnaire, including the International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria, to determine RLS symptoms.
