The Impact of Sarcopenia Definitions and the Association With Lung Function in Older Australians

Year: 2017

Type: article

Abstract: The relationship between sarcopenia and lung function is uncertain. The aim of the current study is to compare the relationship between sarcopenia [using three different definitions for low appendicular skeletal muscle mass (ASM) adjusted for either: a) height squared, b) height and fat mass; or c) body mass index (BMI)], in combination with low grip strength and lung function in 470 (53.4% women) community dwelling older people. Body composition was assessed using DXA and lung function assessed using spirometry. Forced expiratory volume (FEV1) and forced vital capacity (FVC) were significantly correlated with grip strength and the three low ASM definitions. After adjustment for age, gender, smoking and physical activity, ASM adjusted to fat mass definitions of sarcopenia remained independent predictors of lower FEV1 and FVC. Sarcopenia definitions that account for fat mass may therefore be more relevant in clinical practice.
