ABSTRACT
Background: 40% of the general population presents sleep disorders that are associated to chronic pain. Chronic pain is the leading cause of medical attention worldwide. I have been proposed that there is an interaction between both biologic functions (sleep and pain).
Objective: To evaluate the quality of sleep in subjects with chronic non-oncologic pain.
Material and methods: This is a clinical non-randomized study in subjects that seek medical attention in a specialized clinic. Demographic variables (age and gender), pain (intensity and type), and quality of sleep (Pittsburgh sleep quality index, PSQI) were registered.
Results: 383 cases were analyzed. 79% were women and the main age was 62 years (SD: 13). The main pain intensity by means of the visual analogue scale was 5.3 (SD: 2). 90% were considered «bad» sleepers when the PSAQI was used. PSQI global score presented a mode of 7 points. We observed an statistical correlation between VAS pain intensity and PSQI global score (p = 0.000).
Conclusions: It has been reported that pain modifies the perception and the quality of sleep. The real impact of this two variables among the elderly is still a matter of further analysis and study.
