Full4Health: Understanding Food-gut-brain Axis Across the Lifecourse (F4H)

May 19, 2016 updated by: Daniel Crabtree, University of Aberdeen

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'.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Phase 1: Breakfast Study
Other: Breakfast Study
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.
EXPERIMENTAL: Phase 2: fMRI Study
Other: fMRI Study
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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.

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
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Neural responses to images of food when fasted and after consuming a milk-based beverage
Time Frame: There will be one week between both conditions (fasted and fed)
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.
There will be one week between both conditions (fasted and fed)
