Down syndrome (DS) is one of the most common genetic disorders and often associated with feeding problems and tube feeding. Although feeding tubes have a life sustaining function, tube dependency can occur including adverse effects such as frequent vomiting, poor appetite and oral aversion. Although various tube weaning programs exist, their effectiveness in children with DS has been studied only to a limited extent. This study investigated outcomes and growth parameters in tube-dependent children (TDC) with DS who participated in a program based on the “Graz Model of tube weaning”. The current international prospective cohort study included 33 TDC with DS treated between April 2013 and July 2023 (median age: 1.67 years; IQR: 1.00–4.35). Growth data (weight-for-age z scores [WAZ], height-for-age z scores [HAZ], and BMI z scores [zBMI]) were evaluated before and after weaning. The study assessed treatment duration and predictors of weaning success. Overall success rate was 91.67% with an average treatment duration of 79 days. Duration of weaning for younger children (<3 years) tended to be shorter. Post treatment, significant reductions in WAZ (p = .001) and zBMI (p < .001) occurred. HAZ remained constant. The only significant predictor of treatment duration was the degree of change in zBMI and HAZ (p = .001). This study demonstrated that the “Graz model of tube weaning” is effective in the great majority of TDC with DS. Results showed moderate weight loss but that this did not affect overall growth. Future studies should evaluate long-term nutritional and developmental outcomes post-weaning.

Food is interwoven with other elements of a group's culture and identity. In immigrant communities, the importance of food and food establishments can take on new meaning. Yet, limited research exists on food culture for Caribbean immigrants in the United States. Through a case study analysis, this research explored the significance of Crown Bakery – a popular Trinbagonian restaurant and one of the longest operating in Washington, DC – and its use of food and food traditions to communicate parts of Trinbagonian (Trinidadian and Tobagonian) cultural identity. This study relied on online reviews of Crown Bakery and formal and informal interviews with one of the owners of the restaurant. Based on the reviews, customers perceive Crown Bakery to be an inviting locale that celebrates Trinidad and Tobago and is a go-to culinary institution. Meanwhile, the data from the interviews point to Crown Bakery as a signature spot that reflects aspects of Trinbagonian culture – and Caribbean culture, more broadly – and is geared toward being home away from home for Trinbagonians. The findings suggest that the role of food establishments such as Crown Bakery is multilayered. Not only does Crown Bakery promote Trinbagonian and Caribbean culture to those unfamiliar with the region, but it is also a cultural anchor for those with strong ties and fosters community.

食物与一个群体的文化和身份认同的其他元素交织在一起。在移民社区，食物和餐饮场所的重要性可能具有新的含义。然而，有关美国加勒比移民饮食文化的研究却十分有限。通过案例研究分析，本研究探讨了皇冠面包店（一家广受欢迎的特立尼达和多巴哥餐馆，也是华盛顿特区经营时间最长的餐馆之一）的意义，以及它利用食物和饮食传统来传达特立尼达和多巴哥文化身份的部分内容。本研究依据的是网上对皇冠面包店的评论，以及对其中一位店主的正式和非正式采访。从评论来看，顾客认为皇冠面包店是一个令人向往的地方，是一个庆祝特立尼达和多巴哥的美食机构。同时，访谈数据表明，皇冠面包店是一家反映特立尼达和多巴哥文化--以及更广泛的加勒比海文化--的特色餐厅，是特立尼达和多巴哥人的家外之家。调查结果表明，皇冠面包店等餐饮场所的作用是多层次的。皇冠面包店不仅向那些不熟悉该地区的人宣传特林巴贡和加勒比文化，而且还是那些关系密切的人的文化依托，促进了社区的发展。

Sports foods are increasingly being consumed by non-athletes in Australia, despite their intended purpose to supplement additional nutrient intake for athletes. Evidence suggests that these are perceived as regular foods and are being used by non-athletes for purposes contrary to which they were designed, posing health risks. Consumers are also relying on digital media sources for the recommendation of products and using misleading packaging information to select products, although their reasons are unclear. This study aimed to explore non-athlete consumers’ perceptions of the risks, regulations and suggestions for improvement and, how warnings and packaging attributes guide non-athlete sports food choices in Australia. Qualitative semi-structured interviews with 15 non-athlete Australian adult sports food consumers were conducted. Reflexive thematic analysis was used to code responses using NVivo software. Participants had conflicting views on the risks associated with sports food consumption perceiving them to be high risk to others but of limited risk to themselves. Consumers trusted the Nutrition Information Panel and claims more than other attributes, and these were seen as more credible. Digital media was the key source of recommendation for sports food selection. Participants mentioned that warnings were generic, believed they were not applicable to them and that government regulations lacked credibility. Participants also suggested improvements for warning labels and regulatory measures. Consumption of sports foods by non-athletes is influenced by attitudes towards personal risks, the persuasive influence of digital media, and perceptions of the warnings and regulations as inadequate. Findings highlight the need for stricter packaging and regulations that ensure marketing controls and provide safer sports food products to mitigate some of the risks that non-athletes face when selecting these products.

Taking action through stories: Promoting carbon-neutral meat consumption with narrative and message framing

Carbon-neutral meat products offer a unique opportunity to reduce anthropogenic emissions. Supporting the growth of carbon-neutral meat is carbon labelling, an initiative to encourage environmentally friendly behaviour via information transparency. However, the efficacy of carbon labels remains questionable because consumers mainly cannot comprehend and connect with the labels. This raises a question of how communication could be leveraged to bridge that information asymmetry. Through five online controlled experiments, the study demonstrates the usefulness of narrative storytelling and message framing in heightening the effectiveness of carbon labels. Using realistic meat packaging designs with high ecological validity, the results show that even a simple and short-form narrative could be effective in enhancing the efficacy of carbon labels. Follow-up studies repeatedly demonstrate that the positive effect of narrative is accentuated by pairing with a gain-framed message. The effect of such a pairing was underpinned by a heightened feeling of certainty regarding the carbon-neutral meat's environmental impact message comprehension. The findings present a simple but often-forgotten notion that consumers seek optimal decisions with minimal cognitive effort. Hence, when given an alternative that is less cognitively demanding (to decode a message), consumers often prefer such a choice as it was reflected by a favourable attitude and heightened intent to purchase.

Emotional eating and Stress Eating concepts hold that affective experiences can instill the desire for palatable foods. The empirical evidence for such couplings between affective and appetitive systems, however, is mixed and it remains unclear which one precedes the other or whether interindividual differences in such relationships exist. To study the temporal relations between a range of negative and positive emotions and stress on the one hand and snacking behavior on the other, we analyzed over 40.000 questionnaire entries obtained through ecological momentary assessment from 801 participants across nine different studies. Several trait-level eating style questionnaire scores were modelled as moderators for the emotion/stress - snacking relationships. Results showed that stronger boredom was followed by more snacking. Only irritation showed the pattern of reduction following snacking that would be predicted by emotion regulation accounts of emotional eating. Restrained eaters showed larger increases in boredom after snacking (compared to not snacking) than unrestrained eaters. Eating style questionnaires did not significantly moderate any other emotion – snacking – emotion relationships. Together with other recent findings from this dataset (Aulbach et al., n.d.) the present results suggest that eating style questionnaires capture tendencies to experience food cravings, but not snacking, as the latter might be ‘gated’ by several internal and external conditions that our EMA data and the trait questionnaire do not capture well. Accordingly, we suggest a novel terminology for affect-eating relationships that increases precision on the temporal (affects before or after eating/craving) and the phenomenological (snacking, craving) level.

Glucose is critical for normal metabolic function in humans. Accordingly, the ability to sense glucose and glucose-containing saccharides is crucial for maintenance of energy homeostasis. Here, we report the evidence that glucose is perceived relatively stronger compared to fructose or sucralose when subjects are hungry. In the initial experiment, we measured the relative sensitivities between glucose and fructose when subjects were fasted vs. fed. Overnight fasted subjects (n = 22) completed a series of 3-AFC tests comparing one target (glucose from a range of concentrations) and two constants (200 mM fructose) before and after consuming mild-tasting breakfast sandwiches until satiated (738 ± 60 kcal). We found that the relative sensitivity to glucose as compared to fructose was significantly higher when individuals were hungry vs. satiated (p < 0.001). We replicated this finding by comparing the same range of glucose concentrations to a constant sucralose concentration (0.04 mM) (N = 19, p < 0.001). Importantly, when we compared a fixed concentration of sucralose (0.4 mM) to a range of fructose concentrations, we saw no difference in iso-intense concentration before and after eating (N = 19, p > 0.05). These findings support the hypothesis that hunger selectively increases taste sensitivity of glucose compared to other sweeteners.

Intuitive eating is a positive approach to eating involving high responsiveness to hunger and satiety cues. Although the association between intuitive eating and many psychological health indicators is well-documented, its associations with overall diet quality and physical health indicators are less explored. This study aimed to assess whether intuitive eating is associated with adherence to Canada's Food Guide recommendations and with physical health indicators. In the context of the PREDISE study, 1088 French-speaking Canadian adults from the Province of Québec completed a web-based survey including the Intuitive Eating Scale-2. Three web-based 24-h dietary recalls were completed and used to calculate the Canadian Healthy Eating Index (C-HEI) score, an indicator of adherence to Canada's Food Guide. Participants visited the research center to assess physical health indicators (body mass index, waist circumference, blood pressure, cholesterol, and blood glucose). Multiple linear regression analyses were performed to assess how intuitive eating is associated with diet quality and physical health indicators. The total intuitive eating score was not associated with C-HEI (B = 1.47, 95% CI: −0.10, 3.04). However, the “Body-Food Choice Congruence” subscale was positively associated with C-HEI (B = 5.60, 95% CI: 4.44, 6.76), while the “Unconditional Permission to Eat” subscale was negatively associated with C-HEI (B = −4.04, 95% CI: −5.28, −2.80). The total intuitive eating score was negatively associated with BMI in men (B = −4.83, 95% CI: −5.75, −3.91, p < 0.0001) and women (B = −5.01, 95% CI: −6.00, −4.02, p < 0.0001), with waist circumference in men (B = −3.60, 95% CI: −5.33, −1.87) and women (B = −2.20, 95% CI: −3.71, −0.70), and with HDL cholesterol only in women (B = −0.10, 95% CI: −0.17, −0.02). The associations of intuitive eating with diet quality are inconsistent, and only a few associations with physical health indicators were observed.

直觉进食是一种积极的进食方式，它对饥饿和饱腹感的暗示反应灵敏。尽管直觉饮食与许多心理健康指标之间的关系已得到充分证实，但其与整体饮食质量和身体健康指标之间的关系却鲜有探讨。本研究旨在评估直觉饮食是否与《加拿大食品指南》建议的遵守情况以及身体健康指标有关。在 PREDISE 研究的背景下，来自魁北克省的 1088 名讲法语的加拿大成年人完成了一项网络调查，其中包括直觉饮食量表-2。参与者完成了三次基于网络的 24 小时膳食回顾，并利用这些数据计算出了加拿大健康饮食指数（C-HEI）得分，这是衡量是否遵守加拿大食品指南的指标。参与者前往研究中心评估身体健康指标（体重指数、腰围、血压、胆固醇和血糖）。研究人员进行了多元线性回归分析，以评估直觉饮食与饮食质量和身体健康指标之间的关系。直觉饮食总分与 C-HEI 无关（B=1.47，95% CI：-0.10，3.04）。然而，"身体-食物选择一致性 "分量表与 C-HEI 呈正相关（B=5.60，95% CI：4.44，6.76），而 "无条件允许进食 "分量表与 C-HEI 呈负相关（B=-4.04，95% CI：-5.28，-2.80）。男性直觉饮食总分与体重指数呈负相关（B=-4.83，95% CI：-5.75，-3.91，p

The total intuitive eating score was negatively associated with BMI in men (B = −4.83, 95% CI: −5.75, −3.91, p < 0.0001) and women (B = −5.01, 95% CI: −6.00, −4.02, p < 0.0001), with waist circumference in men (B = −3.60, 95% CI: −5.33, −1.87) and women (B = −2.20, 95% CI: −3.71, −0.70), and with HDL cholesterol only in women (B = −0.10, 95% CI: −0.17, −0.02). The associations of intuitive eating with diet quality are inconsistent, and only a few associations with physical health indicators were observed.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"207 ","pages":"Article 107904"},"PeriodicalIF":4.6,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389749","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}

Restrained eating behavior (REB) refers to the tendency to rigidly restrict one's eating behavior in everyday life to influence body shape or weight. Parental overprotection, alexithymia, perfectionism, and asceticism are associated with REB among women. However, no studies have examined these variables simultaneously, integrating them into a theoretical model. In the current study, the combined influences of these variables on women's REB were tested. A total of 412 women (Mage = 23.53 ± 4.24; range = 16–54) completed well-known self-report measures: Parental Bonding Instrument, Toronto Alexithymia Scale, Multidimensional Perfectionism Scale, Protestant Work Ethic Scale, and Eating Disorder Examination Questionnaire. Parallel mediation and moderated mediation hypotheses were tested using PROCESS Model 4 and PROCESS Model 15, respectively. The paths from both maternal and paternal overprotection to REB were mediated through alexithymia and socially prescribed perfectionism. There was a significant interaction effect of asceticism with socially prescribed perfectionism on REB in the model concerning paternal overprotection (b = 0.0185, SE = 0.0091, 95% CI = 0.0007–0.0363). Moreover, asceticism significantly moderated the effect of paternal overprotection on REB through socially prescribed perfectionism (b = 0.0032, SE = 0.0019, 95% CI = 0.0001–0.0076). For the model concerning maternal overprotection, the moderated mediation model was not supported. The findings support a theoretical model of risk factors for REB and highlight the possible mechanisms through which the quality of early parental relationships contributes to REB.

Objective

Several factors (e.g., interpersonal stress, affect) predict loss-of-control (LOC) eating and overeating in adolescents, but most past research has tested predictors separately. We applied machine learning to simultaneously evaluate multiple possible predictors of LOC-eating and overeating severity in pooled and person-specific models.

Method

Twenty-eight adolescents (78.57% female, age = 15.87 ± 1.59 years, BMI %ile = 92.71 ± 8.86) who endorsed ≥ two past-month LOC-eating episodes completed a week-long ecological momentary assessment protocol. Pooled models were fit to the aggregated data with elastic-net regularized regression and evaluated using nested cross-validation. Person-specific models were fit and evaluated as proof-of-concept.

Results

Across adolescents, the median out-of-sample R² of the pooled LOC-eating severity model was .33. The top predictors were between-subjects food craving, sadness, interpersonal conflict, shame, distress, stress (inverse association), and anger (inverse association), and within- and between-subjects wishing relationships were better. The median out-of-sample R² for pooled overeating severity model was .20. The top predictors were between-person food craving, loneliness, mixed race, and feeling rejected (inverse association), and within-subjects guilt, nervousness, wishing for more friends (inverse association), and feeling scared, annoyed, and rejected (all inverse associations). Person-specific models demonstrated poor fit (median LOC-eating severity R² = .003, median overeating R² = −.009); 61% and 36% of adolescents’ models performed better than chance for LOC-eating and overeating severity, respectively.

Discussion

Altogether, group-level models may hold utility in predicting LOC-eating and overeating severity, but model performance for person-specific models is variable, and additional research with larger samples over an extended assessment period is needed. Ultimately, a mix of these approaches may improve the identification of momentary predictors of LOC eating and overeating, providing novel and personalized opportunities for intervention.

Alternative proteins offer promise as a sustainable substitute for traditional meat, but consumer acceptance remains low. Understanding the perceptions and preferences of diverse consumers is critical to shifting consumption patterns globally. Moreover, as children are future consumers, exploring their perceptions of alternative proteins along with parental influences is important for driving change. We conducted semi-structured focus groups with child (9–15 years-old) and parent (38–56 years-old) pairs (n=19) in Singapore to explore (i) current awareness and perceptions of plant-based meat, cultivated meat, and insect proteins, and (ii) facilitators and barriers to consumption. Inductive (reflexive thematic analysis) and deductive approaches (using the Capability, Opportunity, and Motivation model of Behaviour; COM-B) were adopted for data analysis. Overall, we found greater awareness and acceptance of plant-based meat than cultivated meat and insect proteins. Most children presented with a general curiosity to all alternative proteins, wanting to especially understand the likeness of plant-based and cultivated meat to traditional meat. Parents acknowledged that alternative proteins provided an opportunity to add variety to their diet but were concerned with the naturalness of alternative proteins and the novel technologies used to manufacture them. Insect proteins faced fear and disgust, although the historical consumption of insects meant children and parents deemed these as safe. Taste, cost and the impact on health were also commonly discussed by both children and parents. Our findings highlight key factors that influence children and parents’ acceptance and consumption of alternative proteins, which can inform the development of targeted interventions.
