Description
Summary:The finger-ring test (FRT) offers a simple method to screen older adults at increased risk of sarcopenia. To investigate the association between the FRT and lean soft tissue mass estimated by dual-energy X-ray absorptiometry (DXA), and to further elucidate the FRT as an indicator of muscle mass, while accounting for potential confounders, in a community-dwelling population. Within this cross-sectional study 430 community-dwelling individuals aged 18 to 79 (286 women (66.5%) and 144 men (33.5%)) were enrolled. Data regarding FRT and anthropometric measurements were collected. Whole-body composition was estimated using DXA. Binary and ordinal logistic regressions were performed. The frequency of smaller calf, just fits, and bigger calf was 17.7%, 33.7%, and 48.6%, respectively. Regardless of sex, higher appendicular lean soft tissue mass adjusted for height squared was observed for higher FRT categories (p
