Association Between Psoriasis and Sleep Quality Among US Adults: National Health and Nutrition Examination Survey 2009-2014

Current research has been restricted in furnishing nationally representative data regarding the association between psoriasis and sleep quality in US adults. To fill this gap, we conducted a cross-sectional study using data from National Health and Nutrition Examination Survey (NHANES) 2009–2014. We identified 376 (2.83%) cases of psoriasis and 3,615 (29.1%) cases of sleep disorder among 13,002 US adult citizens in present study. The results showed that that psoriasis was significantly associated with sleep disorder in US adults (OR, 1.71; 95% CI, 1.36–2.14), and the association remained in fully adjusted model (OR, 1.46; 95% CI, 1.15–1.86). We also conducted several sensitivity analyses (including IPTW) to access the robustness of our findings. Interestingly, we found that there is no significant association between psoriasis and sleep duration. These findings may be important to consider the poor sleep quality may be exacerbate the psoriasis. Our findings may contribute to future clinical management of sleep quality in psoriasis patients.
