Multiple regression analysis results for PMM
muscle mass, muscle mass of the whole body
CHRONIC DISEASE
PMMp* < 0.01; p** < 0.001; β, standardized coefficient; VIF: variance inflation factor; SEE, standard error of the estimate.Compared with hospitalized elderly injured patients, the cross-sectional area of psoas major muscle increases by 1 cmIt has been confirmed that WBI can be used to estimate the lean mass of the whole body [Results of the present study may be limited in terms of generalizability, including mainly that the participants were all Taiwanese older adults from the community with normal mobility and daily activities, suggesting that the estimation equations derived from this study may only be applicable to Asians aged 60 years or older, and relatively healthy or without chronic disease. If it is necessary to estimate the CSA of the psoas major in certain patients, other ethnicity or subjects of different ages, the applicability of BIA equation may only be confirmed after subsequent rigorous verification. The application of BIA has a great advantage in that muscle mass can be easily measured in a clinical setting. Although there are advantages in estimating muscle mass of the whole body and each segment. At this stage, this approach cannot exactly distinguish individual muscles.
