Association between bone mineral density T-score and respiratory sarcopenia in older adults.

ABSTRACT:

Introduction

Respiratory sarcopenia, characterized by reduced respiratory muscle mass and strength, is underdiagnosed in older adults. This cross-sectional study aimed to investigate the association between bone mineral density (BMD) T-score and respiratory sarcopenia in a Chinese population.

Methods

A total of 530 participants aged ≥60 years were recruited. Respiratory sarcopenia was diagnosed based on peak expiratory flow rate (PEFR) cutoffs. BMD was measured using dual-energy X-ray absorptiometry, and muscle mass was assessed using bioelectrical impedance analysis. Logistic regression models were used to analyze the association between BMD T-score and respiratory sarcopenia risk.

Results

Participants with respiratory sarcopenia exhibited lower BMD T-score, appendic
