Validation of a description of sarcopenic obesity defined as excess adiposity and low lean mass relative to adiposity.

ABSTRACT:

Background

This study aims to assess the construct validity of a body composition-defined definition of sarcopenic obesity based on low appendicular lean mass relative to fat mass (ALMI_FMI ) and high fat mass index (FMI) and to compare with an alternative definition using appendicular lean mass index (ALMI) and percent body fat (%BF).

Methods

This is a secondary analysis of two cohort studies: the National Health and Examination Survey (NHANES) and the Health, Aging, and Body Composition study (Health ABC). Sarcopenic obesity was defined as low ALMI_FMI combined with high FMI and was compared with a widely used definition based on ALMI and %BF cut-points.
