Study Description

Brief Summary

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).

Detailed Description

Background: Food Based Dietary Guidelines (FBDG) need to accessible and understandable to consumers. 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.

Objective: To determine how to express portion sizes and time frame for Food Based Dietary Guidelines (FBDG) using the feedback of dietitians.

Design: Data were obtained from an internet-based survey of 441 French dieticians (collected from November 24, 2013 through January 2, 2014).

Arms and Interventions

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.
