About this study
Official title: How Dieticians Deliver Dietary Guidelines Using Portion Sizes and Time Frame
During the last update of the French FBDG, a survey with a representative sample of dieticians investigated 1) how to communicate portion sizes and 2) the most relevant time frame when delivering dietary guidelines. The objective was to determine how to express portion sizes and time frame for Food Based Dietary Guidelines (FBDG) using the feedback of dietitians. Data were obtained from an internet-based survey of 441 French dieticians (collected from November 24, 2013 through January 2, 2014).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
there was no intervention, only separate analysesOther
We only conducted separate analyses to see if responses differed according to level of experience.
| Study group | Role | What they receive |
|---|---|---|
| Less experienced dietitians | There was no intervention, but we conducted separate analyses to identify differences according to the level of experience of the dietician. We used the median number of years of professional experience (median=8) to split the sample and create two subgroups: 1) less experienced dieticians (less than 9 years of experience; n= 225) Receives: Other: there was no intervention, only separate analyses | |
| More experienced dietitians | and 2) more experienced dieticians (9 years of experience or more; n=215). Receives: Other: there was no intervention, only separate analyses |
What is being measured
The primary outcome is the main question the study is designed to answer.
Questionnaire to measure number of dietitians using different types of portion size and time frame
Open-ended questions to measure how dietitians and patients describe portion sizes and time frame
Measured: through study completion, an average of 1 month

What does the primary outcome measure?
Questionnaire to measure number of dietitians using different types of portion size and time frame (time frame: through study completion, an average of 1 month). 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 6 Feb 2018.
