Abstract

Objective: To evaluate the utility of body mass index (BMI) and corrected-arm-muscle area (CAMA) as measures of nutritional health for lower-limb amputees attending prosthetics clinics.--- Design: Cross-sectional study. Setting: Prosthetics clinic in Australia. Participants: Unilateral lower-extremity amputees (N58; age range, 21–91y; 37 transtibial, 21 transfemoral) attending a regional prosthetics clinic between May and November 2003. Interventions: Not applicable.--- Main Outcome Measures: Weight (without prosthesis), corrected and uncorrected for the amputated limb was used with height estimated from knee height to calculate corrected BMI (cBMI) and uncorrected BMI (uBMI). CAMA was calculated using the mean of triplicate mid-upper-arm circumference (MUAC) and triceps skinfold thickness (TST) measurements. The Mini Nutritional Assessment (MNA) and Assessment of Quality of Life were administered according to recommended protocols. The Pearson correlation was used to determine the strength and significance of associations between variables, and bivariate regression analyses were performed to determine whether an association existed between the nutritional variables (BMI, CAMA, MNA) and quality of life (QOL).--- Results: There were no statistically significant differences in the measures of nutritional health according to site (transtibial, transfemoral) of amputation. MUAC, TST, and CAMA all showed moderate to high positive correlations (r range, .541.782) with both cBMI and uBMI. The strength of the relationship between the MNA and cBMI/uBMI was weaker (r.383, r.380, respectively) but remained positive and statistically significant (P.003). QOL was not associated with cBMI or uBMI but was related to CAMA (.132; P.030) and MNA (.561; P.017).

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
