What this Trial Is About
Researchers are evaluating the impact of a brief education program focused on front-of-pack nutrition labels, including Nutri-Score, in adults living in socioeconomically vulnerable areas in France. This study aims to improve participants' confidence in choosing healthier foods, their food literacy, and the quality of their intended food purchases. The project is conducted in primary care and hospital outpatient settings and later extended to social and community organizations in an area with high rates of diet-related chronic diseases. The intervention consists of 45 to 60-minute group sessions tailored to participants' initial food literacy and nutrition knowledge levels. Participants complete a baseline questionnaire and are then assigned to one or two educational pathways with two intensity levels each. Sessions include discussions and practical activities using real or mock food packages and price scenarios, delivered first by nurses and dietitians, then by trained social workers and volunteers. Participants complete assessments before, immediately after, and one month following the intervention, measuring self-efficacy in food choices, food literacy, and nutritional quality of intended purchases. Researchers also gather feedback to improve the program and build capacity for delivery in social sectors. The total study duration varies, with follow-up assessments at one month after the education sessions.
