PLoS ONE 18(3):Įditor: Yosuke Yamada, National Institute of Biomedical Innovation Health and Nutrition, JAPAN The fast and convenient standing BIA for measuring PMM may be a promising method that is worth developing.Ĭitation: Chu L-P, Chen K-T, Lu H-K, Lai C-L, Huang H-C, Hsieh K-C (2023) Preliminary study on the application of bioimpedance analysis to measure the psoas major muscle in older adults. PMM BIA and PMM CT both correlate highly with MG or VG with small LOA. The correlation coefficient r obtained by incorporating the VG data into the PMM equation was 0.846, and the LOA ranged from -4.55 to 4.75 cm 2. Model performance was confirmed by cross-validation. Relevant variables were estimated using stepwise regression analysis. Estimated variables were height (h), whole body impedance (Z whole), whole body impedance index (h 2/Z whole, WBI), age, gender (female = 0, male = 1), and body weight (weight) by standing BIA. Computed tomography (CT) was used to measure the psoas major area at the’ 元-L4 lumbar vertebrae height as a predictor. Ninety-two older adults with normal mobility were enrolled (47 females, 45 males), and were randomly divided into a modeling group (MG, n = 62) and validation group (VG, n = 30). Aim to develop and cross-validate the psoas cross-sectional area estimation equation of 元-L4 of the elderly over 60 years old by bioelectrical impedance analysis (BIA). For the assessment of sarcopenia or other geriatric frailty syndromes, psoas major area may be one of the primary indicators. ![]()
