Abstract
The aim of the study is to estimate the association between spinal cord injuries related medical factors and subjective sleep disturbance in individuals with short-duration chronic spinal cord injury. Seventy-nine individuals with traumatic spinal cord injuries were included in our study and evaluated using the Beck Depression Index for severity of depressive symptoms, Short-Form Health Survey for quality of life, Douleur Neuropathique 4 score for neuropathic pain severity, and the Pittsburgh Sleep Quality Index for subjective sleep disturbances in a tertiary rehabilitation center. Associated subjective sleep disturbance factors were predicted using multivariate binary logistic regression analysis. Subjective sleep disturbance frequency was 74.7 %, and significantly higher in individuals with paraplegia (P = 0.025, odds ratio, 9.74, 95% confidence interval, 1.21-78.14). Intermittent nighttime catheterization frequency and neuropathic pain severity levels were significantly higher in individuals with subjective sleep disturbance, and quality of life and depressive symptoms were significantly worse in individuals with subjective sleep disturbance. Poor-sleep quality was associated significantly with shorter spinal cord injury duration. The strongest associated factors for sleep disturbance were paraplegic involvement, severity of depressive symptoms (Beck Depression Index score), and quality of life (Short-Form Health Survey general health perceptions score) (odds ratio: 95% confidence interval, 29.75; 1.66-534.36, 1.47; 1.11-1.95, and 0.91; 0.85-0.97, respectively). Our study suggests that paraplegic involvement, low quality of life, and depressive mood are related to sleep disturbance in individuals with traumatic spinal cord injury.
