ABSTRACT

INTRODUCTION Restless legs syndrome (RLS) is a neurological disorder with a prevalence of up to 15%, although little is known about its impact upon quality of life.

AIM To analyse the impact of RLS on health-related quality of life.

SUBJECTS AND METHODS A descriptive cross-sectional study. A random sample of 1,275 subjects over 18 years old, stratified by age, was taken from the urban area of Burgos, with an estimated prevalence, 10%; alpha, 5%; accuracy, 3%; and losses, 70%, using a two-phase study (screening and diagnosis of cases of RLS and non-cases confirmed by a doctor). The clinical and sociodemographic data were collected by means of semi-structured questionnaires, the European Quality of Life-5 Dimensions, the Restless Legs Syndrome Quality of Life Questionnaire, the Epworth Scale, the Goldberg Scale, the Sleep Scale and the International Restless Legs Syndrome Rating Scale.

RESULTS The prevalence of RLS was 5.6% (CI 95%: 2.5-8.7%). Of the total number of cases, 79.4% were women and only 7% had been previously diagnosed with RLS. Intense pain, insomnia and depression-anxiety were more frequent among the cases of RLS than in the controls (p < 0.001 in the three cases). The quality of life among the cases of RLS, especially in women, was poorer than among the controls (p < 0.001). For 11.7% of the cases, RLS made it difficult for the patients to work.

CONCLUSIONS RLS is associated with depression-anxiety, with a significant impact on sleep, on social and work relationships, and on the health-related quality of life. KeywordsAdults Diagnosis Epidemiology Etiology Restless legs syndrome CategoriesCalidad, Gestión y Organización Asistencial Sueño
