Overview

Randomized trial finds a positive association between cardiometabolic index and sleep disorders, indicating higher risks for individuals.

Key Points

  • This research investigates the relationship between cardiometabolic index (CMI) and sleep disorders using NHANES data from 2015 to 2020.
  • Analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2015-2020 with 5,817 participants aged 20 and above.
  • Employed weighted multivariate logistic regression and restricted cubic spline (RCS) regression analysis.
  • Conducted receiver operating characteristic (ROC) analysis to assess predictive performance of CMI for sleep disorders.
  • A one-unit increase in CMI is linked to a 17% increase in the prevalence of sleep disorders (OR = 1.17; 95% CI: 1.06–1.29; P = .004).
  • Participants in the highest CMI quartile have an 81% greater risk of sleep disorders compared to those in the lowest quartile (OR = 1.81; 95% CI: 1.29–2.54; P = .002).
  • The association holds consistent across various subgroups, with body mass index as a significant modifier.
