Restless legs syndrome symptoms in primary care: a prevalence study.

Background: There are relatively few studies on the prevalence of restless legs syndrome (RLS) in the general population, even fewer that used diagnostic questions covering all 4 essential diagnostic criteria defining the RLS symptom complex, and none that have reported on the 2 RLS phenotypes for patients seen by family physicians.

Methods: To determine the prevalence of the symptom complex, diagnostic for RLS in a primary care patient population, a prospective population-based single-center study was performed. Every adult patient presenting for care in a small rural primary care practice with mostly white patients was surveyed for a 1-year period using a validated RLS diagnostic questionnaire.

Symptom-Based Prevalence of Sleep Disorders in an Adult Primary Care Population.

The prevalence of sleep disorders in a primary care physician practice in Moscow, Idaho, was studied between February 7, 1997, and February 6, 1998. This primary care clinic visit population was surveyed for this 1-year period. Every patient above the age of 18 years who visited the Moscow Clinic in this time period was either approached by our on-site researcher during the patient's clinic visit or contacted via mail.
