Dietary Guidelines, Portion Sizes, and Time Frame

January 30, 2018 updated by: Grenoble Ecole de Management

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).

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
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)
Other: there was no intervention, only separate analyses
We only conducted separate analyses to see if responses differed according to level of experience.
More experienced dietitians
and 2) more experienced dieticians (9 years of experience or more; n=215).
Other: there was no intervention, only separate analyses
We only conducted separate analyses to see if responses differed according to level of experience.
