Introduction: Restless legs syndrome (RLS) is a usual [common] neurologic disorder, often undiagnosed and treatable, usually associated with sleep disturbance. Our goal was to study prevalence of RLS in our practice.
Patients and methods: Descriptive, cross-sectional study, in a primary care center. 283 patients 50 years old or older, who came to the office for any reason, were evaluated with a questionnaire about the four essential criteria stated by the International RLS study group in 1995.
Results: Prevalence of RLS was 11.6% (95% CI: 7.9%-15,3%). 73.5% were women and 26.5% men (ratio 3:1). Only 15% reported major repercussion in their quality of life. We estimated that clinically significant RLS is present in 1.9% of our patients. By means of logistic regression only high number of consults at the office, daily sleepiness, and use of hypnotics were associated to RLS.
Conclusions: Prevalence of RLS in patients more than 50 years old is high: 11.6%; but 1.9% of [the 283 patients had] medically significant RLS. Must be suspected especially in women, frequent consults, or with sleep disorders in treatment with hypnotics.
