What is Body Adiposity Index?

▾

The Body Adiposity Index (BAI) estimates body fat % from hip circumference and height without needing weight. Proposed 2011 as an alternative to BMI.

How to Body Adiposity Index

▾
  1. 1BAI = Hip (cm) / Height (m)^1.5 − 18
  2. 2Healthy male: 8–20%; Female: 21–33%
  3. 3Validated against DXA scan measurements
  4. 4No weight scale needed — useful in field settings

Worked Examples

▾
Example 1
Given:Hip 100cm, height 1.75m
परिणाम:BAI = 100/1.75^1.5 − 18 = 25.3%

Frequently Asked Questions

▾
Q

Why use BAI instead of BMI?

A

BMI doesn't distinguish fat from muscle. BAI uses hip circumference (fat-specific). Neither perfect: BAI better for lean populations; DEXA scan gold standard.

Q

What's healthy BAI?

A

Women: 21–32%. Men: 13–25%. Higher = higher visceral fat risk. But BAI underestimates fat in obese populations; use multiple measures.

Q

How do I measure hip circumference?

A

Around fullest part of hips/buttocks (standing, feet together, relaxed). Slight compression, not tight. Measure 3 times, average. Small error = big impact on BAI.
