About this study
Official title: Factors That Determine the Responses to Meal Ingestion: Effect of Ambient Noise
Meal ingestion induces sensations that are influenced by a series of conditioning factors. Aim: to determine the effect of ambient noise on the sensory responses to a standard probe meal. Randomized, cross-over study in healthy subjects comparing the effect of ambient noise versus silence on the sensations induced by a probe meal. Participants (12 men) will be instructed to eat a standard dinner the day before, to consume a standard breakfast at home after overnight fast, and to report to the laboratory, where the test meal will be administered 5 h after breakfast. Studies will be conducted in a quiet, isolated room with participants sitting on a chair. One study day, a noise will applied via headphones for 60 min after meal ingestion and the other day headphones without sound will applied. Perception of homeostatic sensations (hunger/ satiation, fullness) and hedonic sensations (digestive well-being, mood) will be measured at 5 min intervals 10 min before and 20 min after ingestion and at 10 min intervals up to 60 min after the probe meal.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in digestive well-being induced by the probe meal
Effect of noise on digestive well-being [measured by a 10 cm scale graded from -5 (extremely unpleasant sensation) to +5 (extremely pleasant sensation)] by repeated measures ANCOVA (dependent variable: postprandial sensations scores; within subject's factors: noise and time; covariate: premeal scores).
Measured: 1 day
Secondary outcomes (3)
Change in fullness sensation induced by the probe meal
Effect of noise on fullness [measured by a 10 cm scale graded from 0 (not at all) to 10 (very much)] by repeated measures ANCOVA (dependent variable: postprandial sensations scores; within subject's factors: noise and time; covariate: premeal scores).
Measured: 1 day
Change in mood induced by the probe meal
Effect of noise on mood [measured by a 10 cm scale graded from -5 (negative) to +5 (positive)] by repeated measures ANCOVA (dependent variable: postprandial sensations scores; within subject's factors: noise and time; covariate: premeal scores).
Measured: 1 day
Change in hunger/satiety induced by the probe meal
Effect of noise on hunger/satiety [measured by a 10 cm scale graded from -5 (extremely hungry) to +5 (completely satiate)] by repeated measures ANCOVA (dependent variable: postprandial sensations scores; within subject's factors: noise and time; covariate: premeal scores).
Measured: 1 day

Where is the study taking place?
The record lists 1 site in Spain. 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?
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?
Change in digestive well-being induced by the probe meal (time frame: 1 day). 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 NCT03827707, 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 22 Mar 2019.
