Nutrition Labelling Education Program in Socioeconomically Vulnerable Areas

Recruiting now · Not applicable

Conditions studied: Self-Efficacy, Food Choices, Understanding of Front-of-pack Labeling

In brief

Front-of-pack nutrition labels (FoPLs) have been adopted in many countries to help consumers rapidly assess the nutritional quality of foods and to encourage healthier choices. Among these schemes, interpretive systems such as Nutri-Score appear particularly promising, as their graphic design improves understanding and use compared with more complex or purely numerical formats. In France, where social inequalities in diet-related chronic diseases are pronounced, implementing and effectively using FoPLs is especially challenging in socioeconomically vulnerable areas. Seine-Saint-Denis, a department with a markedly higher prevalence of diabetes and cardiovascular diseases than the national average, offers a relevant setting to test prevention strategies embedded within routine care. The PEANUTS project is a quasi-experimental before-after interventional study conducted in primary care and hospital outpatient settings, with later extension to the social sector. It aims to evaluate the effectiveness of a brief, literacy-sensitive nutrition education program focused on on-pack nutrition information (Nutri-Score, nutrition facts panel, claims and marketing elements) on self-efficacy, food literacy and the nutritional quality of purchase intentions among adults living in vulnerable territories.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Respondents must be aged 18
• No formal income criterion is applied; Participants are considered as low-income (justified by the fact that the study is conducted in an area known to be socioeconomically vulnerable).

You may not qualify if…

• Subjects who are homeless
• Subjects who depend exclusively on food aid (Subjects never engaging in grocery shopping)
• Subjects living outside of mainland France
• French language comprehension will be assessed at baseline using functional health literacy questions in the inclusion questionnaire. Insufficient French literacy will not be used as an exclusion criterion at enrolment. Nevertheless, if analyses show that participants who do not speak and read French have outcome scores that are substantially and systematically lower than those of the rest of the sample, these participants may be excluded from planned sensitivity analyses to preserve data quality and comparability.

Where it is running

• Université Sorbonne Paris Nord — Bobigny, France (enrolling)
