ABSTRACT: Objective
Our objective was to explore the association between poor sleep quality and hs_CRP in an adult U.S. population.Methods
This study focused on 9,317 participants in the National Health and Nutrition Examination Survey (NHANES) from 2005-2008 who were aged 20-85 years, completed a sleep disorder questionnaire, and had available information on serum hs_CRP. Sleep quality was classified into three categories (good, moderate, poor) based on the responses of participants to the NHANES sleep disorder questionnaire. High CRP was defined as hs-CRP >1 md/dL. Linear regression model was applied to investigate the association between poor sleep quality and log-transformed hs_CRP. And logistic regression model was fitted to evaluate the association between sleep quality and the risk of high CRP.Results
Females were more likely to report poor sleep quality than males (26% vs. 19%, p<0.0001). Each sleep disorder was significantly associated with increased hs_CRP and correlative to other sleep disorders. In fully-adjusted linear regression model, poor sleep quality was significantly associated with elevated hs_CRP (log transformed) among the overall sample and in females only (β = 0.10, se = 0.03, p<0.01 and β = 0.13, se = 0.04, p<0.01, respectively). In fully-adjusted logistics regression model, poor sleep quality was linked with risk of high CRP(OR: 1.42, 95%CI: 1.15-1.76 in overall sample and OR: 1.59, 95%CI: 1.18-2.14 in females, respectively).Conclusion
We found that poor sleep quality was independently associated with elevated hs_CRP in females but not in males in a U.S. adult population.
