Risk of All-Cause Mortality in Different Muscle Health States Among Community-Dwelling Older Adults

Although muscle health is increasingly recognized as a critical determinant of mortality in ageing populations, existing research has largely concentrated on singular conditions such as sarcopenia or dynapenia. Comparative analyses across a spectrum of muscle health phenotypes are limited. This study investigates the differential mortality risks associated with combined muscle quantity and quality profiles, highlighting potential sex-specific disparities in older individuals residing in community settings.
