The study aims to characterize physical activity (PA) participation by intensity and examine the biopsychosocial correlates among middle-aged and older adults with chronic kidney disease (CKD) in China. Data were examined from the 2011 China Health and Retirement Longitudinal Study. The percentages of participation in vigorous, moderate, and light activity among participants with CKD were 22.7%, 42.1%, and 76.3%, respectively. The participants were less likely to engage in vigorous and moderate PA if they were 70 years of age or older, were not married/partnered, were unemployed, lived in urban areas, had an advanced stage of disease, had heart disease, and/or experienced mobility limitations. The magnitude of the associations between biophysical factors and PA participation was small for light PA. 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.
