Impact of a Front-of-pack Nutrition Label on the Nutritional Quality of Purchases in Campus Cafeterias

Study Overview
=================
Brief Summary
-----------------
This study evaluates the impact of the introduction of a front-of-pack nutrition label on fods and beverages sold in a campus cafeteria in France on the nutritional quality of purchases. The design involves one site with the intervention and one control site with the same consumer and product characteristics.

Detailed Description
-----------------
The introduction of front-of-pack nutrition labelling is thought to help consumers making healthier choices at the point of purchase. Recently, the French government is considering the introduction of the 5-Colour Nutrition Label as a front-of-pack nutrition label. Evaluations of the 5-CNL suggest it is efficient in helping consumers making healthier choices. However, its impact in vulnerable populations has not yet been tested. Students are thought to be a vulnerable population due to their limited resources and to their unhealthy food choices. The objective of the present study is to investigate the impact of the introduction of the 5-CNL in campus cafeterias on the nutritional quality of food purchases. The intervention is conducted during several months, with another similar cafeteria serving as control for the intervention. Data on purchases is collected regularly, and the nutritional quality of purchases is evaluated over time between the intervention situation and the control situation
