Background:
The study aims to characterize physical activity (PA) participation by intensity and examine the biopsychosocial correlates among middle-aged and older adults with CKD in China.
Method:
Data are examined from the 2011 China Health and Retirement Longitudinal Study.
Results:
The percentages of participation in vigorous, moderate, and light activity among participants with CKD were 22.7%, 42.1%, and 76.3%, respectively. Participants were less likely to engage in vigorous and moderate PA if they were 70 years of age or older, not married/partnered, unemployed, lived in urban areas, had advanced disease stage, had heart disease, and/or experienced mobility limitations. The magnitude of associations between biophysical factors and PA participation was small for light PA.
Conclusion:
The higher the intensity of regular PA, the less likely older adults with CKD were to participate; Practitioners could consider the psychosocial characteristics of the older adults with CKD and facilitate their participation in PA.

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...
