Older People Can Learn to Spend Less Time Sitting Down

Retirement may be more golden if less of it is spent in a resting position. Yet older adults spend an average of 8.5 waking hours a day sitting or lying down, according to TABS study leader Dori Rosenberg, PhD, MPH, an assistant scientific investigator at Group Health Research Institute ... "We're not sure whether older people can improve their health by reducing the time they spend sitting," Dr. Rosenberg said. "To prove that, we need randomized trials--and none have been done yet in older adults." As a first step toward such a trial, she conducted the TABS study, which showed that it was feasible to coach adults aged 60 and older to spend less time sitting: an average of 27 minutes less per day ... In the TABS study, health coaches talked by phone with each participant five times during eight weeks. The coaches used motivational interviewing to engage participants in setting personalized goals to sit less by standing and moving more--and to take more breaks from sitting throughout the day. Participants tracked how much they thought they were sitting. And at baseline, midway through the study, and at its end, participants used two devices for a week to measure how much they were sitting. They also received charts showing feedback from these measurements. Participants found the feedback charts most helpful, followed by the coaching phone calls. "The feedback was like a reward for standing up and moving," Mr. Alexander said. more
