CRP and sleep disorder: We further investigated the independent risk factors for sleep disorders using binary logistic regression and found that age (odds ratio [OR]: 1.095; 95% confidence interval [CI]: 1.015–1.182), HCY level (OR: 1.412; 95% CI: 1.202–1.659), CRP (OR: 1.266: 95% CI: 1.020–1.571), TC (OR: 2.542; 95% CI: 1.231–5.248), and HDL (OR: 0.033; 95% CI: 0.009–0.127) were related to sleep quality and were identified as independent risk factors for poor sleep quality (P < .05).
