Lean Mass Index (LMI): Males, Age 85+

What these numbers mean

A value around 16.81 kg/m² is typical (50th percentile) for men in this age group. Scores above about 17.84 kg/m² fall near the 75th percentile or higher, indicating above-average performance. Scores below about 15.23 kg/m² fall near the 25th percentile; about 75% of the reference population scored higher.

These are percentiles for all US adults aged 20 and over, from NHANES 1999-2004 Hologic DXA scans. Values from another scanner brand or calibration are not directly comparable, and percentile position is not a clinical category.
