About this study

Official title: Full4Health: Neuro-gut Interactions in Humans Across the Lifecourse

The primary aim of this work is, to 'relate psychological and behavioural parameters of hunger/satiety and food preference to gut hormones, neural activation and energy metabolism by dietary manipulation, across the human lifespan'.

Read the detailed description

The Full4Health project aims to further understanding of the mechanisms of hunger and satiety. The proposal integrates investigation of human volunteers and laboratory rodents throughout the life course, applying imaging and other cutting edge technologies to critical research questions. Full4Health will combine study of the mechanisms of hunger and satiety with intervention studies to validate the effects of the relevant food characteristics on the regulation of satiety/hunger. The development of cerebral responses to food through the gut-brain axis across lifespan particularly during childhood, adolescence and elderly will be studied.

What participants receive

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

  • Breakfast StudyOther

    Participants (male and female, lean and obese, children, teenagers, adults, and elderly) will take part in 4 morning sessions, consuming a test breakfast milk based beverage and appetite. Biomarkers in blood will be measured and behavioural questionnaires completed. We will also collect a single saliva sample from each participant to examine genetic traits related to appetite, food choice, body weight, and energy expenditure. There will be two milk based beverages, one protein enriched (30% protein from calories) and one normal protein (15% protein). Participants will be offered a morning snack buffet to assess ad libitum energy intake. Phase 1 will also include a subgroup of malnourished male and female elderly participants. However, this group will only complete two morning sessions during which they will consume a low protein and a high protein milk based beverage. Appetite will be recorded and libitum energy intake will be measured. In addition, 24hr energy intake will be recorded.

  • fMRI StudyOther

    We will fMRI scan normal weight and overweight subjects of both gender from the four different age groups only: 8-10, 13-17, 24-45 and 65-75 years. Participants will be measured twice, on separate days, either after an overnight fast or after a test meal, fed to satiation (because hunger will modulate the response to food presentation). The participants will conduct a computerised task that will be performed in the scanner to assess hedonic responses to food cues. Physiological biomarkers will be measured during both trials for the assessment of appetite hormone circulation. Saliva samples will be taken for DNA analysis. DNA extraction techniques will be used to examine genetic traits linked to appetite, food choice, body weight, and energy expenditure.

What is being measured

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

  1. Changes in concentrations of biomarkers of appetite in response to each milk-based beverage

    The following blood-borne biomarkers of appetite will be measured:

    • Glucose
    • Total cholesterol
    • Triglycerides
    • Low density lipoprotein
    • High density lipoprotein
    • Insulin
    • Ghrelin (active)
    • Glucagon-like peptide-1 (active)
    • Peptide YY (total)
    • Leptin

    Measured: During each of the four 'Breakfast Study' visits blood will be taken at baseline, and 30, 60, and 120 minutes after consuming the milk-based beverage. Each visit will be seperated by one week.

Secondary outcomes (1)
  1. Neural responses to images of food when fasted and after consuming a milk-based beverage

    The subjects will conduct a computerised task that will be performed in the functional magnetic resonance imaging (fMRI) scanner. Subjects will be measured twice, on separate days, either after an overnight fast or after a test meal fed to satiation.

    Measured: There will be one week between both conditions (fasted and fed)

Questions about this trial

What is this clinical trial studying?

A study testing Breakfast Study and fMRI Study in people with Obesity, run by University of Aberdeen at 3 sites in 3 countries.

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 6 inclusion and 17 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 20 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Greece, Netherlands, United Kingdom. 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?

Changes in concentrations of biomarkers of appetite in response to each milk-based beverage (time frame: During each of the four 'Breakfast Study' visits blood will be taken at baseline, and 30, 60, and 120 minutes after consuming the milk-based beverage. Each visit will be seperated by one week.). 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 NCT01597024, 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 20 May 2016.
