Comparisons of different indices of low muscle mass in relationship with cardiometabolic disorder
Published online: January 24, 2019
Abstract: This study aimed to evaluate the most valid index among various indices of low muscle mass in assessing cardiometabolic risks in a Korean population. Appendicular lean mass index (ALMI, kg/m2), fat mass index (FMI, kg/m2), FMI-adjusted ALMI, ratio of ALM to weight index, ratio of ALM to body mass index and ratio of ALM to truncal fat index were measured by dual energy X-ray absorptiometry in 17,870 participants from 2008 to 2011. We adopted all the aforementioned indices of low muscle mass expressed as ***- and age-specific standard deviation scores (Z-scores). Low muscle mass for age was defined as Z-score <−1. The prevalence of low muscle mass was approximately 16% across all indices. The receiver operating characteristic curve in metabolic syndrome showed that the ALM to truncal fat index was 0.74 in male and 0.69 in female, indicating that ALM to truncal fat index was the best discrimination index for metabolic syndrome. This study showed that ALM to truncal fat index could be a useful indicator for screening cardiometabolic risk factors, particularly in normal or overweight Asian population.

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD).
An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.
