    This study analyzes the relationship between waist-to-height ratio (WHtR) and obstructive sleep apnea (OSA) risk using NHANES and clinical data.

  • 2

    WHtR was positively associated with OSA risk, with each 0.1-unit increase in WHtR linked to higher odds of OSA in both datasets.

  • 3

    RCS analysis indicated a significant non-linear relationship between WHtR and OSA risk, with thresholds identified at 0.589 for NHANES and 0.523 for clinical data.

  • 4

    WHtR demonstrated superior predictive value for OSA compared to BMI in clinical data, while showing equivalence in population data.

  • 5

    The study suggests WHtR could serve as an effective screening tool for OSA in high-prevalence populations.
