Allergy-related outcomes and sleep-related disorders in adults: a cross-sectional study based on NHANES 2005–2006

Background Epidemiological evidence between the sleep disorders and allergy-related outcomes is limited. Objectives The purpose of the present study was to estimate the relationship between sleep disorders and allergy-related outcomes in adults. Methods We built logistic regression models to examine the associations between sleep disorders and allergy-related outcomes in adult participants using the 2005–2006 NHANES database. Allergy-related outcomes included sIgE levels, asthma, hay fever, sneezing, wheezing, and eczema. Sleep disorders included sleep latency, sleep length, sleep problems, OSA symptoms, and daytime sleepiness. A t-test was used for between-group comparisons. Results Participants with OSA symptoms had 2.72 × higher odds of experiencing hay fever and 1.54 × higher odds of having eczema compared to Non-OSA symptoms participants. Participants with insufficient sleep (≤ 6 h/night) had 1.27 × higher odds of developing allergic sensitisation compared to participants with adequate sleep (7–8 h/night). Sneezing was positively associated with sleep problems (OR: 1.706; 95% CI 1.386, 2.099), OSA symptoms (OR: 1.297; 95% CI 1.049, 1.605), and daytime sleepiness (OR: 1.569; 95% CI 1.205, 2.04). Conclusion Our findings suggest a positive association between allergy-related outcomes and sleep disorders. In particular, OSA symptoms, daytime sleepiness, and sleep problems are strongly associated with allergic conditions. Graphical Abstract
