Hip Circumference Measurement
Hip circumference should be measured at the level of the maximum protrusion of the buttocks, which typically corresponds to the widest part of the hips and the greater trochanters.
Measurement Technique
While the provided evidence focuses primarily on waist circumference measurement protocols, the standard anatomical approach for hip circumference differs fundamentally from waist measurement:
Proper Hip Circumference Protocol
- Patient positioning: The patient should stand upright with feet together and arms at their sides
- Measurement level: Place the measuring tape horizontally around the buttocks at the point of maximum circumference
- Tape positioning: The tape should be:
- Parallel to the floor
- Snug against the skin without compressing soft tissue
- Positioned at the widest part of the buttocks/hip region
- Timing: Measurement should be taken at end of normal expiration
- Recording: Document to the nearest 0.1 cm or millimeter
Clinical Context
Hip circumference is most commonly used in combination with waist circumference to calculate the waist-to-hip ratio (WHR), which serves as an indicator of body fat distribution and cardiometabolic risk. The guidelines emphasize that waist circumference is measured at the iliac crest 1, but hip measurement requires a different anatomical landmark—the maximum gluteal protrusion.
Common Pitfalls to Avoid
- Incorrect landmark: Do not measure at the iliac crest (this is for waist circumference)
- Clothing interference: Ensure minimal, light clothing that doesn't add bulk
- Asymmetric tape placement: Verify the tape is level all around the body
- Compression: Avoid pulling the tape too tight, which artificially reduces the measurement
- Inconsistent positioning: For serial measurements, replicate the exact same anatomical level
The measurement should capture the maximum circumference of the hip/buttock region, which provides the most clinically relevant assessment for body composition analysis and risk stratification.
