Introduction: The impedance vector produced by an alternating current in the bioimpedance analysis can be seen as a standardised test of cellular mass and function since reactance is believed to reflect the mass and integrity of cell membranes. This study investigated the association between resistance and reactance normalised for height (R/H and Xc/H), and muscle function as assessed by hand grip strength.
Methods: 363 patients (172 male, 191 female) from Berlin and Copenhagen were included in the analysis.
Objective: Disease severity is considered an important risk factor for malnutrition in hospitalized patients. We investigated the effect of social factors and disease parameters on the development of malnutrition.
Methods: Nutritional state was assessed by the Subjective Global Assessment in 794 consecutively admitted patients in two hospitals in Berlin (n = 493, university hospital; n = 301, district hospital).
Background: Muscle dysfunction is a common finding in malnourished patients and is associated with poor outcome. We investigated whether the Subjective Global Assessment (SGA) is a valuable tool for identifying malnutrition-related muscle dysfunction.
Methods: Two hundred eighty seven consecutive patients were assessed on admission to hospital according to the SGA, anthropometric measurements, and to the results of bioelectrical impedance analysis.
Background/aims: Malnutrition is common among hospitalized patients. We investigated whether certain diseases predispose more frequently for malnutrition than others.
Methods: Nutritional state was assessed by clinical scores, anthropometry and bioimpedance analysis in 502 consecutively admitted patients in the departments of internal medicine in two hospitals in Berlin (n = 300, university hospital; n = 202, district hospital).
