Population-specific modifications of the short-form Mini Nutritional Assessment and Malnutrition Universal Screening Tool for elderly Taiwanese.

Background: The Mini Nutritional Assessment (MNA) and the Malnutrition Universal Screening Tool (MUST) are two widely used malnutrition screening scales.

Objective: The study was to compare the grading ability of the two scales, and to determine whether adoption of population-specific anthropometric cut-points could improve the grading ability of these tools and whether calf circumference (CC) could be an acceptable alternative to BMI in these scales.

Design: Purposive sampling.
