Step count prescription strategy can up steps/day
Kaberi Dasgupta, M.D., from the McGill University Health Centre in Montreal, and colleagues examined the effects of physician-delivered step count prescriptions and monitoring. Participants were randomized to a control arm or an active arm, in which they were provided with pedometers and recorded step counts. Physicians reviewed their records over a one-year period and provided a written step count prescription with a goal of a 3,000-step/day increase (individualized rate of increase). Participants in the control arm were advised to engage in 30 to 60 minutes of physical activity per day. Seventy-nine percent of the 347 participants completed the final evaluation.
The researchers found that there was a net increase of 20 percent in steps/day for active versus control participants (1,190 steps). Inconclusive changes were seen in carotid femoral pulse wave velocity. Among participants with type 2 diabetes, active versus control participants experienced a lowering of hemoglobin A1c (−0.38 percent). The active versus control arm also showed a decrease in homeostasis model assessment-insulin resistance (−0.96 in all participants not treated with insulin).
"A simple physician-delivered step count prescription strategy incorporated into routine clinical practice led to a net 20 percent increase in step counts, though below the 3,000 steps/day targeted increment," the authors write.
