INTRODUCTION: Insomnia is a sleep disorder characterized by a deficient or poor quality sleep, with adverse daytime consequences. Prevalence is 30-50% in adults and can be associated with depression or lead to the development of this condition. Despite the high prevalence rates, is a unrecognized, misdiagnosis and undertreated. There is not much publications about its prevalence in patients with chronic diseases. OBJECTIVES: to determine prevalence and clinical characteristics of insomnia in outpatients with chronic diseases. MATERIALS AND METHODS: Prospective observational cross-sectional descriptive study. Insomnia was defined based on ICSD-2criteria. The data collection was performed by a questionnaire. RESULTS: We surveyed 100 patients who attended the consultation of various clinical specialties, mean age 50 years old, 57% were women. Sixty nine per cent of them met criteria for insomnia. The most prevalent diseases were hypertension: 57%, asthma 20%, diabetes: 18% and hypothyroidism: 17%. Among patients with insomnia, 62% were women, 35% had insomnia without another illness, and the remaining 65% had secondary conditions associated with insomnia (60% depression). 25% of patients consulting for insomnia ever. The prevalence of criteria for depression in outpatients with chronic diseases was 52%, amounting to 63% in patients suffering from insomnia. DISCUSSION: The prevalence of insomnia in patients with chronic diseases is high (in outpatients with chronic disease: 69%), higher than the average rate described in the general population. It is an undertreated condition. CONCLUSIONS: The prevalence of insomnia in patients with chronic diseases is high, it is underdiagnosed and undertreated. It is associated with depression in high rate.
