What is being measured
The primary outcome is the main question the study is designed to answer.
Time (minutes) spent in various activities (sleeping, being sedentary, standing and stepping) measured by the ActivPAL accelerometer
The ActivPAL accelerometer senses limb position and activity. From this information, it can reliably discriminate periods of upright activity from seated or lying activities. Furthermore, the cadence (stepping rate) of upright activities can be accurately recorded. Energy expenditure (estimated by the ActivPAL accelerometer using Metabolic Equivalent of Task (MET)) and cadence (step frequency, i.e., steps per minute) will be used to distinguish between sleeping, being sedentary, standing and stepping. The time spent sleeping, being sedentary, standing and stepping will be measured and compared against global recommendations of physical activity (e.g., WHO recommendations).
Measured: 7 days

Questions about this trial
What is this clinical trial studying?
An observational study of Physical Activity and Sedentary Lifestyle, run by Maastricht University at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
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?
Time (minutes) spent in various activities (sleeping, being sedentary, standing and stepping) measured by the ActivPAL accelerometer (time frame: 7 days). 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 NCT03513341, which also lists 4 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2019.
