The influence of muscle size and density, as well as subcutaneous adipose tissue, on mortality risk in elderly women across different age groups.

ABSTRACT:

Aims

To investigate whether the size and density of proximal femur muscle and surrounding subcutaneous adipose tissue (SAT) are associated with the risk of mortality in elderly women with hip fractures (HF) across different age groups, and to assess how this association changes over time following the fracture.

Methods

Between January 2020 and July 2022, CT images and data were retrospectively collected from 337 female patients diagnosed with low-energy acute HF, with an average follow-up duration of four years. The study measured the cross-sectional area and density of the gluteal muscles surrounding the hip, the thigh muscles, and the adjacent SAT. The Cox proportional hazards model was employed to assess the covariable-adjusted risk of death from HF across different age g
