Restless Legs Syndrome Research

Sleep disorders are often not regarded as an important health problem, despite their impact on heath. Insomnia is the most frequent sleep disorder in mental health. The aim is to quantify the prevalence of insomnia in a population with schizophrenic disorder and assess its influence on quality of life. This is a descriptive, analytical and cross-sectional study conducted in a sample of 267 schizophrenic patients over 18 years of age using consecutive non-probabilistic sampling. The variables of interest were collected by means of the "Cuestionario Oviedo de Sueño," "Insomnia Severity Index" and EuqoQol-5D. The estimation of insomnia in our schizophrenic population according to the International Classification of Disease (ICD-10) criteria was 23.2%. The likelihood of insomnia when there are problems in the quality of life is significant in all its dimensions: mobility OR: 3.54 (95% CI 1.88– 6.65), self-care OR: 2.69 (95% CI 1.36–5.32), usual activities OR: 3.56 (95% CI 1.97–6.44), pain/discomfort OR: 4.29 (95% CI 2.37–7.74) and anxiety/depression OR: 3.01 (95% CI 1.61–5.65). The prevalence of insomnia fluctuates depending on the diagnostic criteria; however, the schizophrenic population shows high prevalence in some clinical characteristics. People with insomnia have a lower quality of life.
