“…The estimates of FFM of these women were within the range but somewhat lower than previous reports for well elderly women (Reed et al, 1991;Blanchard et al, 1990;Broekhoff et al, 1992;Ferry et al, 1992;Visser et al, 1995) and lower than the reference value (37 kg) for the average elderly female with a BMI of 25.6 kg/m 2 proposed by Forbes (Forbes, 1987). In very close agreement with our ®ndings, Fiatarone et al (1991) reported a value for FFM of 34.5 AE 6.0 kg estimated Figure 1 Correlations between fat-free mass (Bio-impedance Spectrum Analyzer) and functional status indicators in free-living frail elderly women (n 28).…”

“…In this context, BIS represents an interesting inexpensive alternative for the estimation of body composition, despite a " x AE s.d. b Estimated from bioelectrical impedance using multi-frequency (Ferry et al, 1992 and present study) or single frequency (50KHz) (Blanchard et al, 1990 andBroekhoff et al, 1992) methodology.…”

“…FFM was likely to be overestimated in these two subjects since their calculated ratios of extra-to intracellular water were very low. Table 1 shows body composition data calculated from BIS for our frail elderly women compared to data from three previous studies using a similar methodology in slightly younger, apparently healthy, elderly women who were living autonomously (Blanchard et al, 1990;Broekhoff et al, 1992;Ferry et al, 1992). Despite a similar BMI, the amount of FFM was lower in the frail as compared to autonomous elderly women.…”

Objectives: (1) To describe body composition of the frail elderly, (2) To relate lean body mass to muscle strength and functional ability, and (3) To assess temporal stability of strength measures and index of functional ability. Design: Cross-sectional study. Setting: Community-dwelling. Subjects: Thirty frail elderly women (81.5 AE 7 y) recruited from residences or out-patient facilities. Methods: Total body fat and fat-free mass (FFM) were determined using multi-frequency bioelectrical impedance analysis and predicted from anthropometry. Handgrip strength, biceps and quadriceps strength, functional capacities (Timed`Up & Go') as well as self-perceived health and functional status were measured. Reliability was assessed using two separate observations made one week apart by the same examiner. Results: Mean height, weight and body mass index were 1.52 AE 0.04 m, 60.4 AE 10.7 kg and 26.0 AE 4.8 kg/m 2 respectively. FFM (34.1 AE 4.6 kg) was lower than previous reports for autonomous elderly females and associated with all measures of muscle strength (Pearson's r 0.42±0.62, P 0.02), but not with performance on the Timed`Up & Go' or self-perceived health and functional status. Strength measures correlated signi®cantly with different subscales of self-perceived functional capacities and were signi®cantly lower among women with a low %FFM (n 19) and those reporting pain (n 11) as compared to other women. Excellent temporal stability for muscle and functional measures was observed (ICC 0.80±0.90). Conclusions: Muscle strength was strongly related to FFM in free-living frail elderly women especially in the absence of pain.

“…In the literature there are several prediction equations for BIA, generally developed from younger populations, and their accuracy in the elderly has not been adequately confirmed. Although age-specific prediction equations of BIA have been suggested for assessing body composition in the elderly (Broekhoff et al, 1992), there exist few such equations developed from elderly populations (Deurenberg et al, 1990;Baumgartner et al, 1991;Svendsen et al, 1991;Roubenoff et al, 1997). Moreover, their generalized application to other elderly populations is limited by the fact that BIA equations are population specific and need to be validated in the actual population in which they are to be applied .…”

Abstract:Background: There is no consensus regarding the accuracy of bioimpedance for the determination of body composition in older persons. Objective: This study aimed to compare the assessment of lean body mass of healthy older volunteers obtained by the deuterium dilution method (reference) with those obtained by two frequently used bioelectrical impedance formulas and one formula specifically developed for a Latin-American population. Design: A cross-sectional study. Participants: Twenty one volunteers were studied, 12 women, with mean age 72±6.7 years. Setting: Urban community, Ribeirão Preto, Brazil. Measurement: Fat free mass was determined, simultaneously, by the deuterium dilution method and bioelectrical impedance; results were compared. In bioelectrical impedance, body composition was calculated by the formulas of Deuremberg, Lukaski and Bolonchuck and Valencia et al. Results: Lean body mass of the studied volunteers, as determined by bioelectrical impedance was 37.8±9.2 kg by the application of the Lukaski e Bolonchuk formula, 37.4±9.3 kg (Deuremberg) and 43.2±8.9 kg (Valencia et. al.). The results were significantly correlated to those obtained by the deuterium dilution method (41.6±9.3 Kg), with r=0.963, 0.932 and 0.971, respectively. Lean body mass obtained by the Valencia formula was the most accurate. Conclusion: In this study, lean body mass of older persons obtained by the bioelectrical impedance method showed good correlation with the values obtained by the deuterium dilution method. The formula of Valencia et al., developed for a Latin-American population, showed the best accuracy.
