About this study

The objective of this study is to assess the impact of objective sleep duration on blood glucose control in type 1 diabetes adult patients.

This study will also evaluate the impact of objective sleep duration on blood pressure over a 24-hour period and the impact of objective sleep duration on quality of life.

Last, it will investigate the influence of objective physical activity duration on blood glucose control, blood pressure and quality of life.

The objective of this study is to assess the impact of objective sleep duration on blood glucose control in type 1 diabetes adult patients.

This study will also evaluate the impact of objective sleep duration on blood pressure over a 24-hour period and the impact of objective sleep duration on quality of life.

Last, it will investigate the influence of objective physical activity duration on blood glucose control, blood pressure and quality of life.

This study will enrol ambulatory patients only. On day 0, patients receive an actimeter and an ambulatory blood pressure monitoring device. The actimeter measures activity and sleep duration. The patient keeps the actimeter for 3 consecutive days and the blood pressure monitoring device for 24 hours. A blood sample is also collected.

Patients will be divided into 2 groups, based on objective sleep duration: 'short-sleepers' and 'long-sleepers'. The threshold will be the median of the total population. HbA1c will be compared between the 2 groups with a Student test or a Mann-Whitney test, depending on the normality of distribution.

A model of multiple linear regression will be created. HbA1c will be entered as dependant variable and objective sleep duration as independent variable

Patients will be divided into 2 groups, based on objective activity duration: 'low-activity' and 'high-activity'. The threshold will be the median of the total population. HbA1c, blood pressure, quality of life, biological results and general characteristics will be compared between the 2 groups with a Student test or a Mann-Whitney test, depending on the normality of distribution. Qualitative variables will be studied with a chi-square test.

What participants receive

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

  • Actimeter + blood pressure monitoringDevice

    Also called Actiwatch-16, Mini-Mitter Inc, Bend,Oregon, SPACELABS 90207

    Patients will receive an actimeter that they will wear for 3 days and an ambulatory blood pressure monitoring device that they will keep for 24 hours.

What is being measured

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

  1. HbA1c in %

    Measured: Day 0 or Day 3

Secondary outcomes (3)
  1. Objective sleep duration in minutes

    Measured: Day 0 to Day 3

  2. Blood pressure in cm Hg

    Measured: Day 0, 24 hours

  3. Quality of life assessed through questionnaire

    Measured: Day 0 to Day 3

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted23 Nov 2009 (estimated)
  2. Study startNov 2009
  3. Primary completionApr 2012
  4. Study completionApr 2012

Why it stopped: intermediary analysis was performed and significant results were found for the main objective

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes, run by University Hospital, Grenoble at 1 site in France.

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 4 inclusion and 8 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: stopped early, as of the sponsor's last update on 5 Oct 2012. 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 France. 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 was stopped early (reason given: intermediary analysis was performed and significant results were found for the main objective). Results are not available in the source record.

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?

HbA1c in % (time frame: Day 0 or Day 3). 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 NCT01017965, which also lists 1 linked publication.

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 5 Oct 2012.
