Association between sarcopenia and respiratory function in elderly orthopedic outpatients

Area of Science:

• Gerontology
• Orthopedics
• Pulmonology

Background:

• Sarcopenia prevalence and its impact on respiratory function are understudied in elderly Japanese orthopedic outpatients.
• Understanding this relationship is crucial for comprehensive geriatric care in orthopedic settings.

Purpose of the Study:

• To investigate the association between sarcopenia and respiratory function in elderly Japanese orthopedic outpatients.
• To determine if sarcopenia is a risk factor for impaired lung function in this population.

Main Methods:

• A cohort of 102 elderly orthopedic outpatients (≥65 years) was assessed.
• Sarcopenia was evaluated using bioelectrical impedance analysis, grip strength, and walking speed.
• Respiratory function, including percent vital capacity (VC) and percent forced expiratory volume in 1 second, was measured.

Main Results:

• The prevalence of sarcopenia was 25.5% among the participants.
• A significant association was found between sarcopenia and decreased percent vital capacity (VC).
• Logistic regression, adjusted for confounders, confirmed sarcopenia's link to lower VC (OR, 1.73; 95% CI: 1.02-2.97).

Conclusions:

• Sarcopenia is associated with reduced respiratory function, specifically lower vital capacity, in elderly Japanese orthopedic outpatients.
• These findings suggest a potential link between muscle mass and lung health in this demographic.
• Further research is warranted to establish causality and explore clinical implications.
