“…Data from healthy white men, ages 50 to 80 y, and a BMI range from normal weight to obese [22] showed a relative reduction in xC/H and increase in R/H in aging, indicating reductions in BCM and fat-free mass (FFM). An increase in the R/H component indicates a reduction in hydration status and was also found in groups of healthy older people in an earlier study [26]. However, after correction for body size and circumferences, there was no longer any significant effect of age on R; however, the downward reduction in xC remained.…”

ObjectiveBioelectrical impedance vector analysis (BIVA) and phase angle (PA) have been shown previously to indicate relative nutritional status in patients. The aim of this study was to investigate the application of BIVA and PA assessments in a cohort of frail older hospital patients and compare these assessments with malnutrition risk screening by MUST (Malnutrition Universal Screening Tool), and the MNA-SF® (Mini-Nutritional Assessment-Short Form). MethodsSixty-nine patients (n = 44 men; n = 25 women; age 82.1 ± 7.6 y [range 62-96 y]; body mass index 25.8 ± 5.4 kg/m2 [range 16.6-45.1 kg/m2]) were recruited from hospital wards specializing in the care of frail older individuals from the United Kingdom. Bioelectrical impedance assessment was performed at 50 khz frequency, BIVA was performed using raw impedance data, PA was calculated, and data were compared against reference population groups. Patients were categorized by malnutrition risk by MUST and MNA-SF.

“…Indeed, muscle mass loss is a progressive component of ageing, exacerbated by limited physical activity and not linked to age-associated diseases [24]. Bioelectrical impedance analysis demonstrates a clear trend toward a reduction of lean mass with age [25]. In addition, a longitudinal study confirmed a significant decrease in fat-free mass and body water in both sexes from age 75 to 80 yrs, even in the absence of significant body weight changes [26].…”

Chronic obstructive pulmonary disease (COPD) and ageing may contribute to malnutrition. We aimed to explore whether COPD and ageing determine malnutrition in different manners.460 stable COPD outpatients (376 males and 84 females) from the Extrapulmonary Consequences of COPD in the Elderly (ECCE) study database were investigated (age 75.0¡5.9 yrs; forced expiratory volume in 1 s 54.7¡18.3% predicted). Nutritional status was evaluated using the Mini Nutritional Assessment1 (MNA) questionnaire. From the MNA, three scores exploring the domains of the nutritional status were calculated: body composition, energy intake and body functionality scores.Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages were negatively correlated with five MNA items exploring mobility, patient's perception of own nutrition and health status, and arm and calf circumferences (lowest Spearman's rho (rs)5 -0.011; highest p50.039). GOLD stages were independently correlated with body composition and body functionality scores (model r 2 50.073). Age was negatively correlated with four MNA items exploring loss of appetite, fluid intake, mobility and autonomy in daily life (lowest rs5 -0.013; highest p50.030). Age was independently correlated with body functionality score (model r 2 50.037). Severe COPD and ageing are independent and probably concurrent conditions leading to malnutrition. The MNA questionnaire allows a valuable insight into the complexity of components of nutritional status and may provide useful clues for treatment strategies.

“…A further instrument for routine evaluation of body composition, widely applied in geriatric populations, is the BIA (Bioelectrical Impedance Analysis), which is the measure of the impedance by cells to the flow of an electric current, especially in its vectorial interpretation called BIVA (Bioelectrical Impedance Vector Analysis) (9)(10)(11)(12). Some previous studies compared the MNA scores with the values of body masses derived from the conventional BIA (13,14), while only a few studies investigated this comparison using the BIVA (15,16).…”
