About this study
While Food reward is an important component of the appetite control to consider, there is actually no tool that has been developed in French to perform its evaluation.
The Leeds Food Preference Questionnaire (LFPQ) is a validated and recognized tool to assess food reward, being however developed for British populations.
The aim of this work is to validate a French version of the LFPQ among lean and obese adults.
Read the detailed description
50 lean and 50 patients with obesity between 20 and 55 years old (50% women and 50% men), will be recruited. After an evaluation of their body composition by impedance meter, and of their dietary status by questionnaires (TFEQ/DEBQ), they will be asked to perform twice the same experimental sessions. They will be asked during this session to arrive at 08:00 am after a 12-hour fast and will receive a calibrated breakfast. Before and after a lunch calibrated meal, they will be asked to perform the French version of the computerized questionnaire LFPQ. Appetite feelings will be assessed at regular intervals.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Visit 1Behavioural
the participants will fill in the LFPQ questionnaire before and after a lunch test meal
Visit 2Behavioural
this is a replication of Visit 1, testing the reproducibility of the LFPQ and of its response to a meal.

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 was stopped early (reason given: The sanitary conditions and material restrictions imposed by the CHU and by the university laboratories drastically hampered the realization of this work (with restricted access to the laboratory/department).). 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?
Change in Food reward (time frame: day 1 , day 8). 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 NCT04041830, 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?
