Self-Reported vs. Device-Measured Sedentary Time in Adults with Chronic Kidney Disease

Abstract

Adults with chronic kidney disease (CKD) tend to have high amounts of sedentary time, but few studies have compared self-reported and device-measured sedentary time. This is an exploratory secondary analysis of a pilot sedentary-reducing intervention in adults with CKD (n = 18). Sedentary time was evaluated with the Sedentary Behavior Record and an inclinometer. At baseline, sedentary time was 793.9 (SD = 144.4) minutes/day via self-report and 725.0 (SD = 135.5) minutes/day via device (absolute percent error 20.4%). At end-of-study, sedentary time was 778.6 (SD = 157.1) minutes/day via self-report and 725.4 (SD = 144.9) minutes/day via device (absolute percent error 23.7%). In research with adults with CKD, it is reasonable to measure sedentary time via self-report and device to obtain unique, yet complementary, information about sedentary behavior.
