About this study

Reduced appetite can occur with ageing and is linked to a higher risk of undernutrition, poorer physical function and becoming frail. Strategies to increase appetite are needed to improve healthy ageing. This study follows on from previous work which has found a novel ingredient in whey protein (derived from whole milk) that may help to increase appetite and energy intake. This study will compare the effects of the ingredient added to an oral nutritional supplement (ONS) versus the ONS alone versus the ingredient dissolved in water on appetite in older adults. By studying this nutrition supplement in older adults, this will help to provide greater information on possible nutrition strategies to improve healthy ageing.

What is being measured

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

  1. Pre-meal and changes in Hunger

    Validated 100-millimetre Visual Analogue Scales (VAS) will be used to assess hunger, at ten (10) set time points throughout the experimental visit. This VAS has anchors located at each end of the scale. On the left end of the scale, the extreme negative response (0 mm) is represented, while the right end (100 mm) represents the positive response. Participants mark along the line where it most represents their subjective perception between both ends. Hunger is directly obtained from its VAS rating. Changes between fast and post-meal, mean and AUC values will be calculated.

    Measured: 9.5 hours: fast (pre-ONS), pre-breakfast: 90 (post-ONS), 60, 30 and 0 min; post-breakfast: 0 and 180 min (pre-lunch); post-lunch: 0 and 90 min (pre-ONS); 0 min post-ONS; estimated 120 min. post-ONS (pre-dinner); 0 min. post-dinner

  2. Energy Intake (EI) from an ad libitum breakfast meal (kilocalories)

    First meal (ad libitum breakfast) energy intake measurement. Participants will be served a standardised ad libitum breakfast in the laboratory. EI (kilocalories) will be measured objectively, by weighing foods before and after consumption and calculating energy intake based on their nutritional data.

    Measured: Measures taken immediately following the ad libitum test meal (a single measurement)

  7. Pre-meal and changes in Composite Appetite Score

    Validated 100-millimetre Visual Analogue Scales (VAS) will be used to estimate changes in appetite, assessed at ten (10) set time points throughout the experimental visit.

Questions about this trial

What is this clinical trial studying?

A study testing Oral Nutritional Supplement, Oral Nutritional Supplement + Whey Protein Hydrolysate and Whey Protein Hydrolysate + still water in people with Aging and Appetite Loss, run by University College Dublin at 1 site in Ireland.

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 9 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: status not confirmed, as of the sponsor's last update on 27 Jun 2024. 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 Ireland. 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. Some participants in this study may receive a placebo. 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?

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?

Pre-meal and changes in Hunger (time frame: 9.5 hours: fast (pre-ONS), pre-breakfast: 90 (post-ONS), 60, 30 and 0 min; post-breakfast: 0 and 180 min (pre-lunch); post-lunch: 0 and 90 min (pre-ONS); 0 min post-ONS; estimated 120 min. post-ONS (pre-dinner); 0 min. post-dinner). The study lists 2 primary outcomes in all. 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 27 Jun 2024.
