Relationship of Serum 25-Hydroxyvitamin D Levels with Sarcopenia and Body Composition in Community-Dwelling Older Adults: A Paired Case-Control Study

Sarcopenia is a leading health problem among older adults. However, few studies have explored the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels, sarcopenia, and body composition in older Chinese individuals. The aim of this study was to investigate the relationship of serum 25(OH)D levels with sarcopenia, sarcopenia indices, and body composition in community-dwelling older Chinese adults.
