A descriptive qualitative study design was used. Convenience sampling was used to recruit fathers of children aged 3–21 years old from a general paediatric outpatient clinic in a tertiary public hospital. Data were collected from September 2023 to January 2024. Fifteen fathers were interviewed until data saturation. A semi-structured interview guide was used to conduct virtual interviews and thematic analysis was used for data analysis. Three themes and nine subthemes were identified. The three themes were: (1) laying a good foundation, (2) circumstances shaping perspectives, and (3) agents of future behavioural change. Fathers perceived themselves as influencing their children's eating habits by laying a good foundation and that their perspectives were influenced by their circumstances such as lack of time and gender roles. Fathers identified elements that could initiate their future behaviour change to better influence their children's eating habits. These findings provide nuanced insights into paternal perceptions, for the future development of father-specific interventions to enhance their influence in promoting good eating habits among their children. Healthcare professionals can encourage paternal involvement through providing health education on healthy nutrition for their children to both mothers and fathers in the clinical setting. Healthcare professionals can also organize hands-on events that teach about food exploration and nutrition for fathers to take part in with their children.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"206 ","pages":"Article 107835"},"PeriodicalIF":4.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880643","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}

Visual cues and primes are popular implicit nudging techniques for promoting healthier consumption habits. The present review and meta-analysis was conducted and reported according to PRISMA guidelines. It aimed to evaluate the effectiveness of these cues and primes for nudging consumption-related behaviours. Six electronic databases were comprehensively searched for experimental studies on the use of non-marketing-based visual cues/primes on food/beverage consumption. Sixty-six studies from 52 articles were included, resulting in 205 comparisons categorised into seven groups for separate analyses: (1) healthy food- and (2) body-related nudges, and (3) unhealthy food- and (4) body-related nudges, versus neutral controls; (5) mixed-health food- and (6) body-related comparisons; and (7) nudges not inherently health-related. Overall, nudges effectively influenced consumption-related behaviours. Healthier food- and body-nudges encouraged healthier behaviours relative to neutral controls and less healthy nudges, and unhealthy food-nudges, relative to neutral controls. Non-health-related nudges influenced behaviours in the expected direction, relative to comparison/control conditions. Nudge effectiveness, especially for unhealthy food-nudges, was moderated by participant age and weight, nudge timing (prime/cue) outcome measure (intake/choice), health (mixed/healthy/unhealthy), and whether the outcome was real or hypothetical. A range of participant, nudge, and outcome-related mechanisms proposed to underlie nudge effectiveness were also identified. Findings supported the efficacy of visual cues and primes for eliciting changes in consumption-related behaviours, indicating they may be effective for encouraging healthier consumption, when the right nudges are used. Results also indicated that different forms of nudges may be more appropriate in different circumstances (e.g., for different types of participants or food-related outcomes). Further research is needed to thoroughly comprehend the mechanisms underlying these nudges and their effectiveness.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"206 ","pages":"Article 107813"},"PeriodicalIF":4.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food-related emotional expectancies are the anticipated positive and negative emotions from eating different foods and are theorised to affect eating behaviour, and to be amenable to change. The Anticipated Effects of Food Scale (AEFS) assesses food-related emotional expectancies using 62 one-word items; however, a shorter questionnaire would be useful in large and clinical studies. In the present study, we developed a brief version of the AEFS, named the AEFS-Brief (AEFS-B), using a data-driven approach. We identified candidate items from all-subset correlations with the AEFS and item-level correlations with eating behaviours in two community samples (<em>n</em> = 247, <em>n</em> = 718), and we assessed internal consistency and validity of the AEFS-B. We further assessed internal consistency and validity in two independent samples (<em>n</em> = 200, <em>n</em> = 108) that completed a ‘bogus’ taste test or 24-h dietary recalls. Results indicated that the AEFS-B with 28 one-word items had good internal consistency and convergent validity with the AEFS. Analysis with AEFS-B scores reproduced associations of AEFS scores with intake of added sugars, symptoms of food addiction, eating to cope motives, and <em>ad libitum</em> food intake. We also demonstrated novel associations of AEFS and AEFS-B scores with emotional eating and diet quality. The AEFS-B appears to be a reliable and valid brief measure of food-related emotional expectancies that can be used in cohort and population studies, ecological momentary assessments, and for clinical populations in which participant burden is high.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"206 ","pages":"Article 107843"},"PeriodicalIF":4.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142890784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we investigated the boundary conditions for the hypothetical link between the exposure and the norm perceptions, focusing on the type of content (i.e., ads vs. user-generated content) and individual characteristics (i.e., algorithmic media content awareness). We applied a data donation approach to collect YouTube data on users' exposure to food-related content and combined this with a survey. With the data from 102 respondents, no significant association between unhealthy food content exposure (i.e., frequency and proportion) and perceived unhealthy food norms was found. Explorative analyses revealed, however, a significant negative association between unhealthy food content exposure (i.e., frequency) and perceived healthy food norms, and this association was more pronounced when individuals encountered more user-generated food content (vs. food ads). Interestingly, this pattern emerged only for injunctive norms but not for descriptive norms.

The interviews were thematically analysed, and a final step adopted a phenomenographic approach. The results reveal that the children thought of V&amp;F as healthy, but their knowledge of V&amp;F's health effects was fragmented and lacked context.

From the children's thoughts and experiences, the following elements were identified as influencing their V&amp;F consumption: (1) the V&amp;F's taste and serving style, (2) the impact of others, (3) beliefs about V&amp;F's healthiness and (4) their conscious habits and choices. The researchers categorised the children's different ways of relating to the elements as the following approaches to children's V&amp;F consumption: ‘The food determines what I eat’, ‘Other people determine what I eat’, ‘My knowledge determines what I eat’ and ‘My conscious habits determine what I eat’. We suggest that future efforts to promote children's V&amp;F consumption consider these approaches, for example by supporting peer norms, sensory play and training and more comprehensive age-appropriate explanations of V&amp;F's health effects as well as educational tools that empower children to self-monitor habits that facilitate their adequate consumption of V&amp;F.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"206 ","pages":"Article 107819"},"PeriodicalIF":4.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
