Body composition data from a female reference group (n = 62, mean age 29 years) provided cut-off values for defining sarcopenia.Results: Elderly women had higher body mass index (P < 0.001), lower lean mass (P < 0.001), and higher fat mass (P < 0.01) than the young reference group. Only a small proportion (3.2%) had absolute sarcopenia (defined by appendicular skeletal muscle mass/height squared) whereas 37% had relative sarcopenia class II (defined by percentage skeletal muscle mass). Scores for TUG and WS indicated relatively poor physical function, yet these measures were not associated with muscle mass or indices of sarcopenia. In multivariate analysis, only hip abductor strength predicted both TUG and WS (both P = 0.01).Conclusion: Hip strength is a more important indicator of physical functioning than lean mass. Measurement of hip strength may therefore be a useful screening tool to detect those at risk of functional decline and requirement for additional care. Further longitudinal studies with a range of other strength measures are warranted.Keywords: aged care, body composition, muscle strength, sarcopenia Julie L WoodsSandra Iuliano-BurnsSusannah J Kinget alDove Medical Pressarticleaged carebody compositionmuscle strengthsarcopenia.GeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 6, Pp 67-76 (2011)
