A 9-Year Mailed Exercise Program Barely Moved the Needle in Older Women
This study suggests low-touch mailed reminders alone rarely produce big activity changes, especially past age 80.
Nearly 50,000 women aged 66 to 99 were randomly assigned to a long-running, remotely delivered program that encouraged more movement and less sitting. After almost nine years, the group getting the nudges walked and exercised about 3 to 4 percent more and sat about 1.5 percent less. Real, but small. The effect was strongest in the youngest women and faded in those over 80.
