Trial summary

The purpose of REACT project is to provide cost-effective way to promote physical activity and reduce sedentary time among older adults. This is done by examining the efficacy of activity tracker based intervention on wake-time physical activity, sedentary time, sleep and other health outcomes among recent retirees.

About this study

Official title: Enhancing Physical Activity and Healthy Aging Among Recent Retirees - Randomized Controlled In-home Physical Activity Trial

The purpose of REACT project is to provide cost-effective way to promote physical activity and reduce sedentary time among older adults. This is done by examining the efficacy of activity tracker based intervention on wake-time physical activity, sedentary time, sleep and other health outcomes among recent retirees. REACT study will be the first randomized physical activity trial targeted to time window right after retirement.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Polar Loop 2 activity trackerDevice

    The participants were instructed to aim to reach the daily activity goal, initially set at stage 1 as per the goals set by the trackers' manufacturer. The daily activity goal was based on user's typical daily activities, gender and age. The stage 1 daily activity goal corresponded to ~1h/day of jogging or ~2h/day of walking or ~7h/day household activities or a combination of these activities. The tracker gave an inactivity alert as a vibration and text "it's time to move" on the screen of the tracker if the user has been still for 55 minutes.

No activity trackersNo interventionControl group members were requested to abstain from the use of any type of activity trackers and they were informed that they will receive the activity trackers and guidance for using them after the follow-up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in wake time physical activity

    Accelerometer based measurement

    Measured: Primarily change from baseline to 12 months, secondarily change from baseline to 3 months and to 6 months.

Secondary outcomes (4)

  1. Change in wake time sedentary activity

    Accelerometer based measurement

    Measured: Primarily change from baseline to 12 months, secondarily change from baseline to 3 months and to 6 months.

  2. Change in sleep duration and quality

    Accelerometer based measurement

    Measured: Primarily change from baseline to 12 months, secondarily change from baseline to 3 months and to 6 months.

  3. Change in metabolic profile

    Fasting blood sample: lipid profile (total cholesterol, HDL, LDL, triglycerides), fasting plasma glucose, HbA1C, and CRP; blood pressure: systolic and diastolic blood pressure; body composition: fat mass, fat free mass, body weight, waist circumference

    Measured: Baseline to 12 months

  4. Change in activity locations

    GPS-tracking provides data of the latitude, longitude, and time, i.e. when and where an individual is located.

    Measured: Baseline to 12 months

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in wake time physical activity (time frame: Primarily change from baseline to 12 months, secondarily change from baseline to 3 months and to 6 months.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03320746, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
