Waist-to-Height Ratio for OSA Risk: Analysis of NHANES and Clinical Data

200 clinical patient records from Tianjin Chest Hospital and data from the National Health and Nutrition Examination Survey (NHANES) were analyzed by Yajing Li. The study demonstrates a positive association between waist-to-height ratio (WHtR) and obstructive sleep apnea (OSA) risk. The dataset was last updated on 2026-05-29.

Use Cases

• Training predictive models for OSA risk based on waist-to-height ratio.
• Comparing the predictive performance of WHtR against BMI and waist circumference.
• Conducting subgroup analyses of OSA risk across sex and age strata.

Strengths

• Includes a clinical dataset of 200 patients with polysomnography-confirmed OSA.
• Provides specific odds ratios (e.g., OR 2.780 for NHANES) and AUC values (e.g., 0.883 for clinical data) for WHtR.
• Compares results from a large, nationally representative survey (NHANES) with a targeted clinical cohort.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The clinical data is from a single center in China, which may limit generalizability.
