title: Sleep disturbance in Moroccan patients with ankylosing spondylitis: prevalence and relationships with disease-specific variables, psychological status and quality of life.
abstract: Sleep disturbance is often reported by the patients with ankylosing spondylitis (AS), with awakenings produced by inflammatory pain. There are limited studies about sleep disturbance on these patients, and especially its association with psychological state and quality of life to examine the prevalence of sleep disturbance and to assess its association with disease-specific variables, psychological status and quality of life. One hundred and ten patients were included in this cross-sectional study according to the modified New York criteria for AS. Clinical and biological parameters were evaluated. Sleep disturbance was assessed by the fourth item of Hamilton Anxiety Scale. Psychological status was assessed by The Hospital Anxiety and Depression Scale including depression subscale and anxiety subscale. The quality of life was evaluated by the short form-36 (SF-36). Sleep disturbance was found in 64.5 %, depression in 55.5 % and anxiety in 60.9 % amongst our patients. Significantly, worse pain, higher disease activity and functional disability were present in patients with sleep disturbance. Likewise, sleep problems were significantly higher in patients with depression, anxiety and in patients with low scores of the SF36. Multivariate logistic regression analysis revealed that the pain (OR = 1.019) and depression (OR = 1.304) were independent risk factors that influenced sleep disturbance. Sleep problems are prevalent amongst Moroccan patients with AS. Our findings suggest that pain and depression were the independent risk factors that influenced the sleep disturbance and hence, the need for evaluation and optimal management of pain and depression to improve sleep quality in AS patients.
