Introduction:
Lung transplant recipients are often physically inactive and are at risk of developing comorbidities. We investigated whether objectively measured physical activity was associated with the prevalence of comorbidities.
Methods:
Physical activity (accelerometry) and the presence of cardiovascular disease, symptoms of depression and anxiety, diabetes, dyslipidaemia, hypertension, lower extremity artery disease, muscle weakness, obesity, and osteoporosis were assessed in 108 lung transplant recipients. Patients were divided into four groups based on daily step count.
Results:
A cohort of 108 patients (60 ± 7 years, 51% male, 20 ± 14 months since transplantation) was included. Active patients (>7,500 steps/day) had significantly fewer comorbidities (4 comorbidities) compared to severely inactive patients (<2,500 steps/day, 6 comorbidities), and muscle weakness and high symptoms of depression were less prevalent. Severely inactive patients had significantly more cardiovascular comorbidities compared to all other groups. No other significant differences were observed.
Conclusion:
Physically active lung transplant recipients have fewer comorbidities, lower prevalence of muscle weakness, and fewer symptoms of depression compared to very inactive patients.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
