In the present study we assessed the impact of removing price-based incentives on consumer food selection through a virtual, hypothetical, OOH delivery platform. Participants ordered a hypothetical meal for their household using a virtual ordering platform which presented the menu of a popular UK pizza chain restaurant/takeaway outlet. Participants were randomly allocated to one of 5 experimental conditions: control (all price-based incentives present), price reductions removed (e.g., 25 % off when you spend £10), value pricing removed (product size increase for a disproportionately small price increase), bulk-buy reductions removed (meal deals at discounted prices), and all price-based incentives removed. We examined the impact of removing each of the price-based incentives individually and simultaneously on hypothetical food purchases (energy selected (kcal) and money spent). There was a main effect of price-based incentive experimental condition on energy selected (F(4, 1919) = 3.51, p = .007) and money spent (F(4,1919) = 163.48, p &lt; .001) and there was no evidence that effects of removing price-based incentives differed by participant characteristics. Participants in the control condition had a significantly lower hypothetical spend than all other conditions. Kcal selected tended to be lower in the all price-based incentives removed condition compared to the control condition (−7 %) and other conditions (average −8 %), although only the difference between all price-based incentives removed and value pricing removed conditions reached pre-specified statistical significance (−364 kcal; p &lt; .0125; d = 0.21). Bayes Factors indicated that for all other pairwise comparisons the data did not provide strong evidence to support either the presence or absence of an effect. Therefore, further research is necessary to assess the impact of removing price-based incentives in OOH food settings.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"215 ","pages":"Article 108228"},"PeriodicalIF":4.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the reasons driving parents' choices of commercial snacks for their infants amid growing concerns over their nutritional content. Semi-structured interviews were conducted with 22 parents of infants and toddlers aged 6–18 months in Switzerland. Parents were also asked to show all the commercial snacks available at their homes that they provide to their infants and toddlers. Our interviews revealed that convenience was the primary criterion for selecting commercial baby, child, and adult snacks in general, with health considerations being of secondary importance. Nonetheless, some commercial baby snacks were perceived to provide additional health benefits. The safety of commercial baby snacks, particularly in terms of texture and ingredients, emerged as a key factor influencing their purchase, despite the higher costs. The analysis of 151 photographs of commercial snacks (N = 101 different snack products) present in participants’ homes and intended for their infants and toddlers, combined with insights from the interviews, revealed that although several parents acknowledged the benefits of baby-specific snacks, they still frequently chose commercial snacks marketed for older children or adults for their infants and toddlers. Commercial snacks selected included 59 % infant, 17 % child, 25 % adult snacks. This behavior reflected a trade-off in parental selection criteria, influenced by practical factors, such as cost considerations and the perception that baby-specific snacks become less necessary as children grow. Our findings indicate that the food industry, policymakers, and healthcare professionals should work together to support parents in choosing age-appropriate snacks for infants and toddlers. Key actions may include making baby snacks more affordable, raising awareness of safety benefits, and ensuring clear, consistent labelling.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"214 ","pages":"Article 108219"},"PeriodicalIF":4.6,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about how WRSM app use impacts users outside of clinical contexts. This study examined how a non-clinical sample of emerging adults believed that using WRSM apps impacted them, both behaviorally and cognitively. Qualitative data come from semi-structured interviews from the Tracking-EAT study. Participants (n = 25) were emerging adults (M_age = 24.9 ± 1.8 years) who reported WRSM app use in the past year and were diverse in gender, ethnicity/race, and socioeconomic status. Inductive thematic analysis was used for qualitative data analysis. Participants reported changes in their dietary intake, increased physical activity, \"obsessively\" prioritizing meeting WRSM goals, and having cognitive and psychological effects from WRSM app use. Dietary implications included picking foods that were easy to track (e.g., prepackaged foods), prioritizing protein, and reducing carbohydrate intake. \"Obsessive\" prioritization including altering social behaviors to meet WRSM goals at the detriment of other aspects of their life, and further increasing intensity of goals. Cognitive and psychological affects included cognitive persistence of tracking and emotional persistence of tracking including feelings of pride, guilt, and shame. Results suggested that the psychological and behavioral implications of WRSM app use may be more negative than previously assumed, including having potentially harmful dietary implications and cognitive outcomes that extend even after WRSM app use stops. Clinicians should screen their patients who use WRSM apps for potential negative consequences associated with their use and provide additional education.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"214 ","pages":"Article 108225"},"PeriodicalIF":4.6,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
