What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether personalized notifications from a Fitbit—about sleep, activity, and nutrition—could improve thinking skills and muscle mass in adults over 65. Over 350 older adults in Japan wore a Fitbit for 6 months and received automatic tips, while a control group got usual care. Researchers compared changes in memory, attention, and muscle strength between the groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Fitbit device with automated notifications on sleep, activity, and nutrition, plus nutritional supplementation and exercise promotion
What this could lead to
If successful, this approach could offer a simple, low-cost way to help older adults maintain cognitive function and muscle mass, potentially delaying frailty.
What could go wrong
This is a completed trial, but the intervention is behavioral and device-based, so results may vary by individual adherence and may not apply outside Japan.
