Standardized diagnostic criteria determined by the International Restless Legs Syndrome Study Group were used to investigate the current prevalence of restless legs syndrome (RLS). Possible associations between RLS and neuropsychiatric and somatic complaints were also investigated. A random sample of 4,000 men living in central Sweden were sent a questionnaire that included questions about sleep habits, symptoms of sleepiness, and somatic and neuropsychiatric complaints. ⋯ RLS sufferers more frequently reported hypertension (OR, 1.5; 95% CI, 0.9-2.4) and heart problems (OR, 2.5; 95% CI, 1.4-4.3). Results show that restless legs syndrome is common among men. It is hypothesized that RLS may be associated with several somatic and neuropsychiatric symptoms.
