Agreement and Predictive Validity Using Less-Conservative Foundation for the National Institutes of Health Sarcopenia Project Weakness Cutpoints.

ABSTRACT:

Objectives

To derive lean mass cutpoints based on a less-conservative Foundation for the National Institutes of Health (FNIH) Sarcopenia Project Weakness cutpoint for grip strength (Weak_I ) and to assess their agreement with European Working Group on Sarcopenia in Older People (EWGSOP) and prediction of incident slow walking and mortality.

Design

Longitudinal analysis.

Setting

Baltimore Longitudinal Study of Aging.

Participants

Individuals aged 65 and older (287 men, 258 women) with 2 to 10 years of follow-up.

Measurements

Weakness was determined according to handgrip strength using a hand dynamometer, appendicular lean mass (ALM) using dual-energy X-ray absorptiometry, and walking speed according to 6-m usual pace walk speed. Analyses were pe
