Abstract
Study Objectives: To investigate the prevalence of restless legs syndrome (RLS) in Korea.
Design: A large population-based telephone interview method using the Korean version of the Johns Hopkins telephone diagnostic interview for the RLS.
Setting: A computer aided telephone interview method
Participants: A total of 5,000 subjects (2,470 men and 2,530 women) were interviewed in depth. A representative sample aged 20 to 69 years was constituted according to a stratified, multistage random sampling method.
Interventions: N/A
Measurements and Results: Of the respondents, 373 respondents (7.5%) of the population (pop) met the criteria for the definite or probable RLS groups: 194 (3.9% of pop) respondents fulfilled the criteria for definite RLS and 179 (3.6% of pop) respondents fulfilled the criteria for probable RLS. The prevalence of RLS was generally higher for women than men (4.4% vs. 3.3% for definite, 8.7% vs. 6.2% for definite plus probable). About 90% of RLS individuals were experiencing symptoms at the time of the interview and this was similar for both RLS groups. Seventy-four respondents (1.48%) reported symptoms were moderately or severely distressing and were therefore classified as RLS “sufferers.” Of those with a diagnosis of RLS sufferer, 24.3% reported being treated for their symptoms, compared to 12.4% of RLS not designated a “sufferer.”
Conclusion: RLS is common and underdiagnosed in Korea with nearly 1% of the population reporting disturbed sleep related to their RLS. These results are comparable to other countries.
