“…Fourteen comparisons (30.43%) indicate more favourable effects of nudging in less disadvantaged participants (23,34,36,41,42,45,47,49). These include one study with affectively oriented nudges (41), with the rest of the studies employing cognitively oriented nudges.…”

Background: Dietary behaviours are among the key modifiable risk factors for non-communicable diseases. Importantly, dietary behaviours vary substantially between groups and individuals with different socioeconomic positions, with more disadvantaged groups and individuals being exposed to more dietary risk factors. The goal of this review is to summarise the existing research on equity effects of dietary nudging interventions.Methods: Systematic review of nudging interventions conducted in a field setting that report an observable indicator of dietary behaviour, include a control group, and report effect sizes stratified by indicators of socioeconomic status as outlined in the PROGRESS-Plus framework. Two databases (scopus, Pubmed) were searched (last search June 2021), and 18 articles with 19 studies (k = 46 equity comparisons) were included. Risk of bias was assessed using the ROBINS-I tool. Due to heterogeneity in equity dimensions and study outcomes, a harvest plot was used to summarise data.Results: The majority of equity comparisons (38 out of 46) were available for cognitive nudges. Most of these (22 out of 38 comparisons) found that cognitive nudges worked equally well in more and less disadvantaged populations; however, in 12 out of the 38 comparisons, they favoured those who were less disadvantaged. Two out of four comparisons on behavioural nudges favoured more disadvantaged persons.Conclusions: The differential effects of dietary nudging interventions in this review can contribute to increases in health inequalities. At the same time, a substantial number of interventions showed no equity effects. Importantly, this review suggests that more research on nudging interventions and health equity is needed. Future interventions should report effect sizes stratified by indicators of social inequality.Systematic Review Registration: PROSPERO (CRD42019137469)

“…In view of the overall positive results not only of our experiment, but also of some studies carried out abroad concerning intervention strategies in school-based collective catering using simple informal labels more or less identical to ours (18,19,29), it is essential to continue this type of research, by combining it with counseling so that its effectiveness can be optimized. It is important for future similar projects in school-based mass catering to consider information, mutual aid and inter-professional training.…”

Background: In October 2017, France adopted the Nutri-Score label as the official food label to display on industrial food packaging. School mass catering is recognized as a substantial contributor to individual diet. Objective: Evaluating the impact of the food label Nutri-score on food choices of students at a school self-service restaurant and at home. Methods: Longitudinal open prospective pilot study conducted in the self-service restaurant of a vocational school in France in 2019. After a survey among guests (T0), food products labeled with the Nutri-Score were presented to consumers on the menus at the entrance and directly on the food dishes at the counters (T1). The intervention was supplemented by a counseling service on healthy diet conducted by a nutritionist (T2). Results: We observed a decrease in students’ consumption of sweet products (57%). Similarly, the self-service catering staff observed at the end of T1 a decrease in food leftovers categorized as less healthy. The implementation of the counseling service at T2 was significantly associated with a higher consumption of fruits and vegetables (P < .001), healthier eating habits at home (P < .001), more home cooking (P < .02), and an increased will to check for the presence of the Nutri-Score labels on supermarket food items (P < .001). Conclusions: After the display of the Nutri-Score label, we observed an improvement in students’ diets. However, results were significant only when the Nutri-Score was associated with a counseling service.

“…Three studies combined salience and affect nudges with messenger and norms, sometimes with other nudge types, and had mixed effects. In a study in a university campus restaurant (Vermote et al, 2020), combined four nudges including icons shaped like a green heart (green was associated with “good”) and “Food Triangle” posters placed above fruit stand items, substitution of items, and social norm messages. Combining green heart icons and Food Triangle posters significantly increased fruit purchases, but the other interventions had limited effects.…”

Objective: Consistent with behavioral economic models that emphasize the context-dependance of behavioral choice, choice architecture strategies change the environmental context to promote or nudge healthier choices including the healthfulness of food purchases that may help reduce disease and premature death. This review summarizes research that investigated nudging interventions to promote healthful food purchase choices among adults. Method: A comprehensive systematized search strategy identified research published since 2009 that investigated the role of nudges and choice architecture interventions on adult food purchasing decisions with behavioral outcomes. Study data were extracted and summarized regarding nudge characteristics, design features, study quality, and food purchasing outcomes. Results: The search identified 1,129 articles, 33 of which met inclusion criteria. Twelve studies were rated as high quality, 21 as neutral, and none as low quality. Some evidence of effectiveness was found for priming nudges that manipulated physical, verbal, or sensational cues to promote healthy choices (8 of 11 studies); salience and affect nudges that used novel or personally relevant cues to direct attention to healthy choices (3/3); messenger nudges that presented information on socially normative food choices (2/2), and default nudges that made healthy options the preset choice (1/2). In studies that combined nudge types, combining priming and salience and affect nudges was at least partially effective in 5 of 5 studies. Conclusions: Nudge applications in food purchasing settings, particularly priming, offers a promising public health strategy to encourage healthier food choices among adults. More research is needed to determine optimal nudge combinations and contexts. Public Health Significance StatementFood purchasing is a key link between the food environment and eating behavior across multiple eating occasions and contexts and for multiple individuals within a household and is thus an important target to promote healthy eating, reduce obesity, and prevent chronic disease. This systematized review of research on the use of nudges and choice architecture to promote healthy food purchases among adults suggests that nudging can be an effective approach to promote healthier food choices. However, more research is needed to determine optimal combinations of nudges that can be implemented in adult food purchasing contexts to promote healthier consumer choices.
