Trial summary

This study aims to investigate 1. whether sleep extension results in improvements of endocrine and metabolic markers of obesity and diabetes in obese teenagers, 2. the relationship between habitual sleep quality and duration and markers of obesity and diabetes in lean and obese teenagers.

About this study

Official title: Sleep and Obesity in Teenagers: Impact of Sleep Length and Quality on Obesity and Diabetes Risks in Teenagers.

This study aims to investigate

  1. whether sleep extension results in improvements of endocrine and metabolic markers of obesity and diabetes in obese teenagers,
  2. the relationship between habitual sleep quality and duration and markers of obesity and diabetes in lean and obese teenagers.
Read the detailed description

Inclusion of 13 obese teens. Duration : 1 week of screening period + 1 week of intervention: habitual/extended sleep length + 1 week of intervention: extended/habitual sleep length. A wash out period of at least 3 months will be required between the two interventions.

Inclusion of 13 non obese healthy teen controls for measuring reference sleep duration and physiology level. Duration for these group: 1 week of screening period + 1 week of habitual sleep length

What participants receive

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

  • habitual sleep length period + extended sleep length periodBehavioural

    On obese group, realisation of an habitual sleep length period followed by an extended sleep length period

  • extended sleep length period + habitual sleep length periodBehavioural

    On obese group, realisation of an extended sleep length period followed by an habitual sleep length period

3ExperimentalStudy of extended sleep length period followed by habitual sleep length period on obese teen group
Receives: Behavioral: extended sleep length period + habitual sleep length period

What is being measured

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

  1. The influence of sleep extension on leptin level for the obese teens group.

    Measured: at the end of each sleep experimental period

Secondary outcomes (3)
  1. Difference between the two groups (obese vs non-obese) regarding sleep length and delta waves activity.

    Measured: during each sleep experimental period (habitual or extended)

  2. Study the correlation between delta waves activity and habitual sleep length

    Measured: During each sleep experimental period

  3. Study the correlation between delta waves activity and psychological, behavioural, anthropometric and physiological markers of obesity and its co morbidities

    Measured: During each sleep experimental period

Questions about this trial

What is this clinical trial studying?

A study testing habitual sleep length period + extended sleep length period and extended sleep length period + habitual sleep length period in people with Obesity, run by Hospices Civils de Lyon 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 5 inclusion and 10 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 3 Aug 2017. 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 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?

The influence of sleep extension on leptin level for the obese teens group. (time frame: at the end of each sleep experimental period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Aug 2017.
