OBJECTIVES: To compare a bioelectrical impedance analysis (BIA) prediction equation for estimating skeletal muscle mass (SM) with magnetic resonance imaging (MRI)‐measured SM and to investigate the prevalence of sarcopenia in community‐dwelling elderly people in Taiwan. DESIGN: Cross‐sectional survey. SETTING: Communities in the district of Zhongzheng, Taipei. PARTICIPANTS: Forty‐one volunteers (aged 22–90) for BIA equation validation; 302 individuals aged 65 and older and 200 adults aged 18 to 40 for the investigation of the prevalence of sarcopenia. MEASUREMENTS: Skeletal muscle mass was estimated using a BIA prediction equation and measured using MRI. RESULTS: No statistical difference between MRI‐measured and BIA‐derived SM was observed (difference of −0.44 ± 1.55 kg, P =.08). The prevalence of sarcopenia in was 18.6% in elderly women and 23.6% in elderly men. CONCLUSION: Estimation of SM using a BIA equation was validated in Taiwanese volunteers. It was confirmed that sarcopenia is an emerging health problem in the aging population in Taiwan.
