Impact of a Front-of-pack Nutrition Labelling on the Nutritional Quality of Purchases of Customers in Contract Catering - a Controlled Trial

This controlled trial investigates the impact of the implementation of a front-of-pack nutrition label, namely Nutri-Score, on foods and beverages sold in a contract catering in France on the nutritional quality of purchases.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The introduction of front-of-pack nutrition labelling is thought to help consumers making healthier food choices at the point-of-purchase. In 2017, the French government has selected the Nutri-Score as single front-of-pack nutrition label to be applied on food products sold in French supermarkets, on a voluntary basis.

Some studies have found that the Nutri-Score would help consumers making healthier choices. Nevertheless, its impact has been demonstrated in experimental supermarkets and its implementation only concerns products sold in groceries and supermarkets, as it is stated in the official decree. The potential impact of the Nutri-Score in contract catering remains unknown, while this sector represents a growing share of out-of-home catering and that the promotion of the Nutri-Score in this sector is now part of the National Public Health Plan.

Thus, the objective of the present study is to investigate the impact of the implementation of the Nutri-Score in contract catering restaurants on the nutritional quality of food purchases. The trial will be conducted using a quasi experimental before/after design with a comparison group. Data on purchases will be collected regularly through receipts, and the nutritional quality of purchases will be evaluated over time on two pairs of sites. In each pair of sites, one site will receive an intervention (Nutri-Score) and one site will be a control site. Within each pair, the sites will be comparable in terms of food offer and consumers profile.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention arm
In this arm (site n°1), participants will purchase their products in the restaurant first in a control phase and then in an interventional phase with the Nutri-Score affixed on food products.
Behavioral: Front-of-pack nutrition label Nutri-Score
The intervention consists of displaying the Nutri-Score on dishes and pre-packed foods.
No Intervention: Control arm
In this arm (site n°2), participants will purchase their products in the restaurant during the whole study without any label affixed on food products.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in the overall nutritional quality of purchases over time
Time Frame: Through study completion, an average of 6 months
Score using the Food Standards Agency nutrient profiling system modified by the HCSP, allocating points depending on the amounts in unfavourable elements (energy, saturates, sugars, sodium) and favorable elements (fibres, proteins and fruits, vegetables, nuts and oils (olive, colza, nuts))
Through study completion, an average of 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
