“…For the calculation of the FFM, a formula for elderly was used for the control subjects [11], while a COPD-specific formula was used for the COPD subjects [12]. FM was calculated by weight minus FFM, FFMI, and FMI was calculated by respectively FFM and FM divided by heigth 2 .…”

The objective of the present study was to determine the association between CT phenotypes—emphysema by low attenuation area and bronchitis by airway wall thickness—and body composition parameters in a large cohort of subjects with and without COPD. In 452 COPD subjects and 459 subjects without COPD, CT scans were performed to determine emphysema (%LAA), airway wall thickness (AWT-Pi10), and lung mass. Muscle wasting based on FFMI was assessed by bioelectrical impedance. In both the men and women with COPD, FFMI was negatively associated with %LAA. FMI was positively associated with AWT-Pi10 in both subjects with and without COPD. Among the subjects with muscle wasting, the percentage emphysema was high, but the predictive value was moderate. In conclusion, the present study strengthens the hypothesis that the subgroup of COPD cases with muscle wasting have emphysema. Airway wall thickness is positively associated with fat mass index in both subjects with and without COPD.

“…In addition, the low number of obese individuals in the study and the absence of well-defined criteria for chronic disease were factors limiting the practical use of these criteria. Dey et al 13 published reference values for FFM measured with BIA for 70-to 75-year-olds. Values were based on estimations of body composition in 823 self-declared healthy elderly from the general population in Sweden.…”

“…Bioelectrical impedance analysis (BIA) is an easily performed and non-invasive way to measure body composition including total body water, skeletal muscle mass and body FM. [8][9][10] The value of BIA in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large groups to define the presence or prevalence of obesity, respectively, is of great interest. BIA appears to be a more accurate measure of FFM and percentage of body fat than body weight, height or BMI.…”

BACKGROUND/OBJECTIVES:To compare the characteristics of body composition for different gender and age in a large number of apparently healthy Chinese subjects, and to determine reference values for fat-free mass index (FFMI) and fat mass index (FMI). SUBJECTS/METHODS: In total, 61 382 Chinese adults (age range: 18-92 years) were consecutively enrolled into the study. Body composition was measured using bioelectrical impedance analysis with a tetrapolar impedance meter. RESULTS: The skeletal muscle mass, fat-free mass (FFM), FFMI and body mass index (BMI) were significantly higher in men than in women (Po0.05), but FM% and FMI were significantly higher in women (Po0.05). In the group with normal BMI (BMI 18.5-23.9 kg/m 2 , 18-92 years), the reference values (5th-95th percentile) of FM%, FFMI and FMI were 9.7-34.5%, 14.15-19.76 and 1.99-7.75 kg/m 2 in men, and 18.1-35. 8%, 13.82-17.89 and 3.68-8.16 kg/m 2 in women, respectively. CONCLUSIONS: Reference intervals for FFMI and FMI could be of practical value for the clinical evaluation of a deficit in FFM with or without excess FM for a given age category, complementing the classical concept of BMI in a more qualitative manner, although these indices are only suggestive indications for the degree of obesity. In contrast to BMI, similar reference ranges of FFMI seem to be more utilizable with advancing age.
