METHODS: This cross-sectional study was conducted after the approval of the review board during February 2023 and February 2024. Inclusion criteria were psoriasis patients aged ≥ 18 years who visited the dermatologic clinic, Siriraj Hospital, Thailand. Demographic data, anthropometric measurements, underlying conditions, types of psoriasis, Psoriasis Area and Severity Index scores, disease duration, percentage of body surface area involvement, Epworth Sleepiness Scale (ESS), and STOP-Bang questionnaire were collected. Patients who were unable to answer these questionnaires were excluded. RESULTS: Of the 200 participants (106 men, 94 women), 108 patients (54%) were identified as high-risk for OSA; of them, 70 were men (64.8%) and 38 were women (35.2%). Within this group, statistically significant differences were observed in male (p < 0.001), age (p = 0.02), and the presence of hypertension, diabetes, and dyslipidemia. Both BMI and an ESS score > 10 were also significantly elevated in the high-risk group (p < 0.05). However, no significant correlations were detected between various characteristics of psoriasis and the risk of OSA. Only male sex [adjusted odd ratios (OR) = 3.51], HT (OR = 2.87), and an ESS score > 10 (OR = 4.13), showed statistically significant associations with an increased risk of OSA (p < 0.05). CONCLUSION: Psoriasis patients had a higher prevalence of high-risk OSA compared to the general Thai population. This underscores the importance of screening individuals with psoriasis, particularly those exhibiting concurrent HT, male sex, and EDS, for OSA.MedicineArticleSCOPUS10.1007/s11325-025-03318-y2-s2.0-1050036156411522170940232659
