Validation of a French-version of the Leeds Food Preference Questionnaire in Normal Weight and Patients With Obesity

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.

Why the study stopped: 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).

About this study

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.

Treatment and study plan

Visit 1

Behavioral

the participants will fill in the LFPQ questionnaire before and after a lunch test meal

Visit 2

Behavioral

this is a replication of Visit 1, testing the reproducibility of the LFPQ and of its response to a meal.

Primary outcomes

  1. Change in Food reward

    Time frame: day 1 , day 8

    The participants will be asked to complete the developed French version of the computer-based procedure to measure food reward (Leeds Food Preference Questionnaire; LFPQ) (Finlayson, King et al. 2008).

Secondary outcomes

  1. Body fat mass

    Time frame: day 0

    the percentage of body fat and the quantity of fat mass will be assessed using Bio-impedance (BIA)

  2. Body fat and fat free mass

    Time frame: day 0

    the percentage of body fat free and the quantity of fat free mass will be assessed using Bio-impedance (BIA)

  3. Dietary status

    Time frame: day 0

    the level of dietary restriction/disinhibition will be assessed using the TFEQ questionnaire.

  4. Dietary status

    Time frame: day 0

    the level of dietary restriction/disinhibition will be assessed using the DEBQ questionnaire.

  5. Hunger

    Time frame: day 1, day 1 + 30minutes, day 1+60minutes, day 1+ 90minutes , day 8, day 8 + 30minutes, day 8+60minutes, day 8+ 90minutes

    the hunger sensation will be assessed using visual analogue scales of 150 mm.

  6. Satiety

    Time frame: dday 1, day 1 + 30minutes, day 1+60minutes, day 1+ 90minutes , day 8, day 8 + 30minutes, day 8+60minutes, day 8+ 90minutes

    the Satiety sensation will be assessed using visual analogue scales of 150 mm.

  7. desire to eat

    Time frame: day 1, day 1 + 30minutes, day 1+60minutes, day 1+ 90minutes , day 8, day 8 + 30minutes, day 8+60minutes, day 8+ 90minutes

    the desire to eat sensation will be assessed using visual analogue scales of 150 mm.

  8. Prospective Food consumption

    Time frame: day 1, day 1 + 30minutes, day 1+60minutes, day 1+ 90minutes , day 8, day 8 + 30minutes, day 8+60minutes, day 8+ 90minutes

    the Prospective Food consumption sensation will be assessed using visual analogue scales of 150 mm.
