Description

Purpose: This study was performed to investigate 1) the relationship between the anthropometric measurements of the upper arm muscle (AMC; arm muscle circumference and %AMC; AMC divided by the age-sex-adjusted medians) and biochemical parameters (total protein, albumin, prealbumin, total cholesterol, and triglyceride) and 2) the relationship between the changes in the anthropometric measurements and the changes in albumin levels.<br>Subjects and Methods: The subjects were 120 elderly patients aged 80.0 ± 2.5 years who underwent consultation with the nutrition support team (NST) at the Iida Municipal Hospital. The anthropometric measurements and the biochemical parameters were measured at baseline and the end of NST intervention.<br>Results: At baseline, AMC and %AMC were positively and significantly correlated with serum albumin and prealbumin levels. However, the three anthropometric measurements did not correlate with total protein, total cholesterol, and triglyceride levels. Multiple regression analysis revealed that albumin was an independent predictor of AMC and %AMC. Additionally, in patients with serum albumin ≧ 3g/dL at end of NST intervention, the change in %AMC did positively correlate with that in albumin levels during NST intervention.<br>Conclusion: AMC and %AMC correlated with serum albumin and prealbumin levels. Our findings indicate that the anthropometric measurement of upper arm muscle is useful for nutrition assessment.
