Sleep disturbance in psoriasis leads to psychological and physical predictors

People with psoriasis often report poor sleep patterns.

Findings of a cross-sectional online survey published in the British Journal of Dermatology suggest that sleep disturbance, which is quite common among people with psoriasis, is associated with a host of psychological and physical factors. The rate of probable obstructive sleep apnea (OSA)in these patients was also high.

The relationship between sleep disturbance and psoriasis has been the focus of much research. In this survey, researchers sought to characterize sleep disturbance in patients with psoriasis and to identify physical and psychological predictors of sleep quality in this population.

The online survey, which was completed by 186 respondents (mean age, 39.2 years), included the following validated measures: (1) Pittsburgh Sleep Quality Index (PSQI), which assessed sleep quality and disturbance over 1 month; (2) Berlin Questionnaire, which assessed an individual’s risk for OSA developing; (3) Morningness-Eveningness Questionnaire (MEQ), which established a respondent’s chronotype (ie, propensity to sleep at a particular time during a 24-hour period); (4) Pre-Sleep Arousal Scale, which quantifies cognitive and somatic arousal during the presleep period; (5) Hospital Anxiety and Depression Scale (HADS), an established measure of a person’s mood; (6) Simplified Psoriasis Index-Severity (SPI-S), which is a self-assessment of psoriasis severity; and (7) 5-D Itch Scale, which assesses the severity and impact of an individual’s itch.

The PSQI includes 19 items that are scored across 7 components, generating a global score that ranges from 0 to 21, with a score ≤5 indicating normal sleep and a score ≥6 denoting poor sleep.

The mean PSQI score of the respondents was 9.2, with 76.3% scoring above the threshold for poor sleep. Of the 186 participants, 61 (32.8%) had a high probability of OSA based on results of the Berlin Questionnaire.
