Trial tests intervention to reduce sedentary time in patients with kidney disease

A recent randomized study tested an intervention to reduce the time spent sitting and increase physical activity in people with kidney disease. The results will be published in an upcoming issue of CJASN.

Sedentary lifestyle is very common in people with chronic kidney disease (CKD), especially those who are advanced in the disease, and is associated with a higher risk of premature death.

A team led by Dr. Srinivasan Beddhu (University of Utah Medical School and Veterans Affairs, Salt Lake City Health System) and Dr. Kate Lyden, Ph.D. (University of Massachusetts, Amherst and Colorado State University) developed a study to investigate whether occasional light-intensity pedaling could reduce sitting time to improve the health and well-being of patients with moderate to advanced CRF.

In this single-center, open, randomized, controlled, pilot study conducted at the University of Utah, participants’ activity was assessed using accelerometers that attached the skin to the midline of the thigh. The 54 patients assigned to the “Sit Less, Interact, Move More” intervention received educational materials, received graphical representations of their accelerometer summaries, and received feedback on when they were most sedentary. They were instructed to get out of the sitting / lying position awake at least once an hour and to participate in activities with light intensity. National recommendations for physical activity were given to the 52 participants in the control group.

The researchers found that by week 20, sitting time decreased by an average of 43 minutes per day, step time increased by 16 minutes per day, and the number of steps per day in the intervention group increased by 1,265. Although the intervention shortened the amount of time patients were sedentary and increased the amount of time they walked, these effects did not persist in the weeks that followed.

“These results suggest that while it is possible to reduce sedentary duration in patients with CRF, additional co-interventions may be required to maintain these effects over the long term,” said Dr. Beddhu.

Dr. Beddhu emphasized that physical inactivity (failure to achieve the weekly goal of moderate / vigorous activity of 150 minutes / week) is different from sedentary behavior (mostly sitting / lying). “You can be physically active and achieve your weekly goal of 150 minutes a week – 2% of wake time – but still be seated by sitting or lying down to remind you of 98% wake time. So it is important to do both address physical inactivity and sedentary lifestyle for healthier lifestyles, “he said.
