RESUMO
Introduction: The association between obstructive sleep apnea (OSA) and insomnia is relatively common but is underrecognized. There are important diagnostic and therapeutic implications of comorbid OSA杋nsomnia overlap but there is no data available from India. Objectives: (1) To find out the prevalence of insomnia among patients with OSA; (2) To compare the demographic characteristics, Epworth sleepiness scale (ESS) scores and the presence of comorbidities among patients of OSA with insomnia vs OSA without insomnia. Materials and methods: It was a prospective observational study involving 250 patients with suspected OSA. A total of 189 patients had OSA based on type I polysomnography and were further analyzed. Insomnia was diagnosed based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Results: The prevalence of insomnia among OSA was 15.34% (29/189). Overlap was seen in 22.45 and 12.86% of women and men respectively among patients with OSA. The prevalence of overlap increased with decreasing severity of obesity and OSA. Those with OSA杋nsomnia overlap had significantly lower ESS scores as compared to OSA without insomnia (12.31 vs 15.24; p = 0.019). A total of 10.34% (3/29) of patients of overlap had depression whereas none from OSA alone had depression. Conclusion: There is a high prevalence of insomnia among patients with OSA (15.34%), similar to findings worldwide. Insomnia is more common among women with OSA. Overlap patients have lower ESS scores and are likely to be depressed.
RESUMO
Abstract Introduction Inadequate sleep hygiene (SH) is considered factor contributing to insomnia. However, the practice of SH by depressed patients with comorbid insomnia has not been explored. Objective We aimed to compare the practice of SH between patients with major depression, comorbid insomnia, primary insomnia, and good sleepers. Method One hundred and eighty-two adult individuals participated: 62 outpatients with major depressive disorder with comorbid insomnia (MDD), 56 outpatients with primary insomnia (PI), and 64 good sleepers (GS). All participants were assessed with a structured psychiatric interview, an insomnia interview, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and the Sleep Hygiene Practice Scale. We compared the practice of SH as a whole and by domains between the groups and the relation between SH practice, insomnia, and sleep quality. Results Patients with PI and MDD showed a significantly worse practice of global SH. In the comparison by SH domains, MDD and PI groups had significantly worse scores than GS in all domains. Individuals with MDD showed a significantly worse practice of sleep schedule and arousal related behaviors than PI group. Although, SH practice was significantly related with insomnia and sleep quality in the whole sample, this association remained significant only in the PI. The arousal-related behaviors domain was the main predictor of insomnia and sleep quality. Discussion and conclusion Although patients with insomnia comorbid with MDD or with PI have a worse SH practice than GS, only arousal-related behaviors and drinking/eating habits contribute significantly to insomnia severity and sleep quality.
Resumen Introducción Una inadecuada higiene de sueño (HS) se considera como un factor que contribuye al insomnio, incluido el insomnio comórbido con trastornos mentales. Sin embargo, no se ha estudiado la práctica de HS en pacientes con depresión e insomnio comórbido. Objetivo Comparar la práctica de HS entre pacientes con depresión mayor con insomnio comórbido, insomnio primario y buenos durmientes. Método Participaron 182 individuos: 62 pacientes ambulatorios con trastorno depresivo mayor con insomnio comórbido (TDM), 56 pacientes con insomnio primario (IP) y 64 buenos durmientes (BD). A todos se les realizó una entrevista psiquiátrica estructurada, una entrevista sobre insomnio, el Índice de Calidad de Sueño de Pittsburgh, el Índice de Severidad de Insomnio y la Escala de Prácticas de Higiene de Sueño. Comparamos la práctica de HS tanto global como por dominios entre los grupos, y la relación entre la práctica de HS, el insomnio y la calidad de sueño. Resultados Los pacientes con IP y con TDM mostraron una práctica global de la HS significativamente peor. En la comparación por dominios, los grupos con TDM e IP alcanzaron peores calificaciones que los BD en todos. La práctica de HS se relacionó significativamente con el insomnio y calidad de sueño en la muestra total, sin embargo, solamente en el grupo con IP se mantuvo significativa. El dominio de conductas relacionadas con el alertamiento fue el principal predictor de insomnio y calidad de sueño. Discusión y conclusión Aunque los pacientes con insomnio comórbido con TDM o con IP tienen peores hábitos de HS que los BD, solamente las conductas relacionadas con el alertamiento y los hábitos de alimentación contribuyen significativamente a la gravedad del insomnio y calidad de sueño.
RESUMO
Chronic insomnia is the most common sleep disorder in adults andits diagnosis is fundamental for adequate clinical management. The aim of this paper is to present recently published definitions of insomnia according to current international classifications, such as the International Classification of Sleep Disorders - Third Edition and the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition. For the first time, these classifications are congruent related to thei rdiagnostic criteria; both present insomnia as a distinct disorder and divide it into acute, chronic and other. This emphasizes the necessityof a specific insomnia approach. Furthermore, it is necessary torecognize those insomniacs with physiological hyperarousal, whichmay be identified by objective measures (short total sleep time, forinstance). These patients may have poorer outcome, as they are athigher risk of developing cardiometabolic conditions and neurocognitive impairment. Diagnosis is primarily made on a clinical basis (anamnesis and physical examination), while sleep diaries and questionnaires (such as Insomnia Severity Index) can help evaluate these patients. Objective measures, such as polysomnography, arenot required in most cases, except when suspicion of another sleep disorder arises.
A insônia crônica é o transtorno do sono mais comum em adultos,e seu diagnóstico é fundamental para o manejo clínico adequado.O principal objetivo deste trabalho é apresentar, em relação à insônia,as definições publicadas recentemente segundo as novas classificações internacionais, como a Classificação Internacional de Distúrbios do Sono - Terceira Edição e o Manual Diagnóstico e Estatístico de Transtornos Mentais - Quinta Edição. Pela primeira vez, essas classificações são congruentes a respeito de seus critérios diagnósticos,pois ambas apresentam a insônia como uma doença em si ea dividem em aguda, crônica e outras. Isso enfatiza a necessidade de uma abordagem específica da insônia. Além do mais, é necessário reconhecer os insones com estado fisiológico de hiper alerta que podem ser identificados por medidas objetivas (tempo total de sono curto, por exemplo). Esses pacientes podem ter pior prognóstico, por causa do maior risco de desenvolver condições cardiometabólicas e comprometimento neurocognitivo. O diagnóstico da insônia é feito principalmente com base em dados clínicos (anamnese e exame físico),e o uso de diário de sono e questionários (tais como o Índice de Gravidade de Insônia) pode ajudar na avaliação desses pacientes.Análises objetivas, como aquelas obtidas pela polissonografia, não são rotineiramente necessárias na maioria dos casos, exceto quando há a suspeita de outro distúrbio do sono.
