Higher waist-hip ratio (adjusted for BMI) causally influences lower sleep duration and lower sleep efficiency.
Managing waist-hip ratio through lifestyle changes may improve sleep duration and efficiency, independent of overall BMI.
GoodSupportsHIGH confidence
we observed evidence that higher waist-hip-ratio (adjusted for BMI) is causally associated with lower sleep duration (P_IVW = 5 × 10−6) and lower sleep efficiency (P_IVW = 3 × 10−4).
Why this rating
Mendelian Randomization analysis provides strong causal evidence.

- Accelerometer-derived measures of sleep duration and quality are heritable and genetically distinct from self-reported measures, with specific genetic variants (e.g., PDE11A, MEIS1) influencing sleep traits.Strong
- Genetic variants associated with restless legs syndrome (RLS) also influence sleep duration, quality, and timing.Good
