Researchers of a recent study aimed to clarify the quantitative effect of psoriasis on sleep quality and the prevalence of sleep disturbances (SD) using standardized questionnaires. Fifteen studies involving 1274 psoriasis patients and 775 controls were included in the meta-analysis. Results indicated that individuals with psoriasis had significantly poorer sleep quality and a higher risk of SD compared to controls. Subgroup analyses showed that this difference was more pronounced in patients with psoriatic arthritis, moderate-to-severe psoriasis, shorter duration of the disease, and younger patients. Additionally, psoriasis patients showed higher scores on the Insomnia Severity Index and Beck Depression Inventory, and an increased risk for Restless Legs Syndrome, but no significant difference in Epworth Sleepiness Scale scores. The study highlights the complex relationship between psoriasis and sleep disturbances, a common issue in clinical practice with reported prevalence varying widely. The study concludes that poor sleep quality and higher risk for sleep disturbances are significant concerns in patients with psoriasis, particularly those with certain disease characteristics.
