Identification of Sarcopenia Components That Discriminate Slow Walking Speed: A Pooled Data Analysis.

ABSTRACT:

Background

The Sarcopenia Definitions and Outcomes Consortium (SDOC) sought to identify cut points for muscle strength and body composition measures derived from dual-energy x-ray absorptiometry (DXA) that discriminate older adults with slow walking speed. This article presents the core analyses used to guide the SDOC position statements.

Design

Cross-sectional data analyses of pooled data.

Setting

University-based research assessment centers.

Participants

Community-dwelling men (n = 13,652) and women: (n = 5,115) with information on lean mass by DXA, grip strength (GR), and walking speed.

Measurements

Thirty-five candidate sarcopenia variables were entered into sex-stratified classification and regression tree (CART) models to agnostically choose variab
