Background:
Psoriasis is a chronic inflammatory skin disorder that is associated with the metabolic syndrome and its components. An association between obstructive sleep apnea (OSA) and the metabolic syndrome was previously observed.

Objectives:
To investigate the association between psoriasis and OSA in a comprehensive community-based database.

Materials and methods:
The study was performed utilizing the medical database of Clalit Health Services. Patients with psoriasis were compared to controls regarding the prevalence of OSA in a case–control study. A logistic multivariate model was used to control for independent covariates.

Results:
The study included 12,336 patients with psoriasis ≥21 years and 24,008 age- and sex-matched controls. The prevalence of OSA in patients with psoriasis was increased compared to the control group (2.7%, 1.5%, respectively, P < 0.001). Multivariate analysis adjusting for age, sex, ethnicity, body mass index, chronic obstructive pulmonary disease, hypothyroidism, hyperlipidemia, and peptic disease demonstrated a significant association between psoriasis and OSA (odds ratio = 1.27, 95% confidence interval 1.08–1.49, P < 0.001).

Conclusion:
We found an association between psoriasis and OSA among a large cohort of patients with psoriasis. Clinicians should take into account that patients with psoriasis may have undiagnosed OSA.
