Researchers analyzed multiple studies to see if using activity trackers and smartphone apps helps older adults become more physically active. They looked at data from over 3,000 people aged 60 and older who lived in their own communities. The studies compared using these digital tools to either doing very little or trying other types of activity programs.
In the short term, right after using the trackers or apps, people walked more. Compared to doing very little, they took about 1,100 extra steps per day. Compared to other activity programs, they took about 900 extra steps per day. However, the researchers note the certainty of this evidence is low to very low, meaning we should not be overly confident in these numbers.
The main reason for caution is that the benefit did not last. The few studies that followed people for 6 months, 1 year, or 2 years found that the increase in steps was not sustained. The review did not report on any safety concerns from using the devices. Readers should understand that while these tools might give a temporary boost, they may not lead to lasting changes in physical activity for older adults on their own.
