To explore the developmental trajectories of sarcopenia and its influencing factors in patients with chronic respiratory diseases.
The data from three waves (2011, 2013, and 2015) of the China Health and Retirement Longitudinal Study (CHARLS) were used to screen patients with chronic respiratory diseases who had sarcopenia-related information. Group-based trajectory modeling was employed to fit the developmental trajectories of sarcopenia in these patients,and multinomial logistic regression was used to analyze the influencing factors.
A total of 1 138 chronic respiratory diseases patients with sarcopenia-related information were included in the study. Four developmental trajectories were identified:the low-risk stable group (38.66%, n=440), the high-risk declining group (15.29%, n=174), the U-shaped risk group (23.46%, n=267), and the high-risk stable group (22.58%, n=257). Multinomial logistic regression analysis indicated that age, gender,education level, body mass index (BMI), disease type, and hypertension were the influencing factors for the developmental trajectories of sarcopenia in patients with chronic respiratory diseases.
The progression of sarcopenia in patients with chronic respiratory diseases is characterized by dynamism and reversibility. Intervention should be preferentially carried out for the elderly, females, individuals with low education levels, low BMI, respiratory system comorbidities, and hypertension to improve muscle function and overall prognosis in patients with chronic respiratory diseases.
