Sleep hygiene and its association with mood and quality of life in people with epilepsy

초록

Objectives: We determined whether sleep hygiene is directly related to mood and quality of life (QoL) in people with epilepsy and, if not, documented the indirect effects of sleep hygiene through sleep quality. Methods: Data were collected from 150 adults with epilepsy. The Sleep Hygiene Index (SHI), Quality of Life in Epilepsy-10 (QOLIE-10), Hospital Anxiety and Depression Scale (HADS), Sleep Problems Index-2 (SPI-2) of the Medical Outcomes Study-Sleep Scale, and Epworth Sleepiness Scale (ESS) were used. To determine the direct and indirect associations between SHI, mood, and QoL, multiple linear regression analyses and the Sobel test were performed. Results: Inadequate sleep hygiene behaviors were answered affirmatively by >= 15% of the participants represented by 6 out of 13 items of the SHI. A younger age was independently related to higher SHI scores (p = 0.013). The higher SHI scores were directly related to lower QoL independent of sleep quality, anxiety, and depressive symptoms( p < 0.05) but not independently related to anxiety and depressive symptoms. The Sobel test confirmed that the SHI scores were associated with anxiety and depressive symptoms through sleep quality (p < 0.001). Conclusions: Inadequate sleep hygiene is independently related to low QoL but indirectly related to anxiety and depressive symptoms through sleep quality. Patients of a younger age are at risk of poorer sleep hygiene. (C) 2015 Elsevier Inc. All rights reserved.
