Aim

This study aimed to evaluate the relationship between sleep quality, hedonic hunger, and adherence to the Mediterranean diet (MD) in early adolescents and to investigate if hedonic hunger would mediate the influence of sleep quality on adherence to the MD.

Method

A total of 786 middle school students (boys, 51%) aged 10–14 years were included in the study. A self-administered questionnaire was used to collect data. Hedonic hunger was assessed with the “Food Power Scale”, sleep quality was evaluated with the “Pittsburgh Sleep Quality Index (PSQI)”, and adherence to the MD was assessed with the “Mediterranean Diet Quality Index (KIDMED)”. Anthropometric measurements were performed. Dietary intake was evaluated with a 24-h food consumption record.

Results

Of the adolescents, 63.4% exhibited poor sleep quality, 59.2% had a moderate adherence score to MD, and 31.7% were classified as short sleepers. Adolescents with high hedonic hunger had significantly higher carbohydrates, but lower protein, and fruits. Adolescents with poor sleep quality and short sleep duration showed a lower proportion of daily fruit or fruit juice intake, dairy products for breakfast, daily yogurts and cheese intake, and a higher proportion of sweets or candy. PSQI significantly predicted hedonic hunger (β = 0.13) and KIDMED (β = −0.15). Hedonic hunger significantly predicted KIDMED (β = −0.122; p = 0.005). Adolescents with short sleep duration (OR = 1.70; 95% CI = 1.21–2.39) were more likely to have obesity/overweight.

Conclusion

The results of the study showed that higher hedonic hunger, lower sleep quality, and short duration are important factors associated with low adherence to the MD in early adolescence. It also showed that hedonic hunger mediates between sleep quality and adherence to the MD. Additionally, short sleep duration increased the risks of obesity in early adolescents.

目的：探讨青少年早期睡眠质量、享乐性饥饿与地中海饮食依从性之间的关系，并探讨享乐性饥饿是否在睡眠质量对地中海饮食依从性的影响中起中介作用。方法：选取786名10 ~ 14岁的中学生（男生占51%）为研究对象。采用自填问卷收集数据。采用“食物能量量表”评估享乐性饥饿，采用“匹兹堡睡眠质量指数（PSQI）”评估睡眠质量，采用“地中海饮食质量指数（KIDMED）”评估MD的依从性。进行人体测量。通过24小时的食物消耗记录来评估饮食摄入量。结果：63.4%的青少年表现为睡眠质量差，59.2%的人对MD的依从性评分中等，31.7%的人被归类为短睡眠者。高享乐饥饿感的青少年碳水化合物含量明显较高，但蛋白质和水果含量明显较低。睡眠质量差、睡眠时间短的青少年每日水果或果汁摄入量、早餐乳制品、每日酸奶和奶酪摄入量的比例较低，而甜食或糖果的比例较高。PSQI显著预测享乐饥饿（β=0.13）和KIDMED （β=-0.15）。享乐饥饿显著预测KIDMED (β=-0.122；p = 0.005)。睡眠时间短的青少年(OR= 1.70；结论：研究结果表明，较高的享乐性饥饿、较低的睡眠质量和较短的持续时间是青春期早期低依从性饮食习惯的重要因素。研究还表明，享乐性饥饿在睡眠质量和遵守饮食习惯之间起着调节作用。此外，睡眠时间短会增加青少年早期肥胖的风险。

The world's growing population is putting immense pressure on natural resources and food security. Algae, as a sustainable and nutrient-rich alternative protein source, have gained attention due to their lower environmental impacts and potential health benefits. However, consumer acceptance remains a key challenge, especially in developing countries where awareness is limited. This study investigates the factors influencing Iranian consumers' willingness to consume algae-based foods through the Theory of Planned Behavior (TPB). A survey involving 445 respondents from Mashhad, Iran, was conducted, and the data were analyzed using structural equation modeling. The findings reveal that attitude has the strongest influence on consumption intention, followed by food disgust, subjective norms, knowledge, moral norms, and environmental concerns. Attitude also mediates the relationships between the constructs of disgust, moral norms, knowledge, and environmental concerns with consumption intention. Furthermore, the findings indicate that attitude constitutes the fundamental mechanism of the relationship between knowledge, environmental concerns, and intention. On the other hand, moral norms confirm the existence of a relationship between the subjective norms construct and consumption intention, such that moral norms shape the fundamental mechanism of the relationship between subjective norms and attitude, emphasizing the profound influence of moral values in Iranian consumption culture. In contrast, food neophobia did not have a significant impact on consumption intentions, indicating an openness towards dietary innovations among Iranians. This research contributes to the theoretical advancement in this field by identifying the direct, indirect, and total effects of the extended Theory of Planned Behavior components on the decision to consume algae or algae-containing foods. Practically, the findings from this study can provide guidance for effective introduction and promotion strategies of algae-based food products in emerging markets.

世界不断增长的人口给自然资源和粮食安全带来了巨大的压力。藻类作为一种可持续的、营养丰富的替代蛋白质来源，因其对环境影响较小和潜在的健康益处而受到关注。然而，消费者的接受度仍然是一个关键的挑战，特别是在认识有限的发展中国家。本研究通过计划行为理论（TPB）调查了影响伊朗消费者消费藻类食品意愿的因素。对来自伊朗马什哈德的445名受访者进行了调查，并使用结构方程模型对数据进行了分析。调查结果显示，态度对消费意愿的影响最大，其次是食物厌恶、主观规范、知识、道德规范和环境问题。态度还在厌恶、道德规范、知识和环境关注等构念与消费意向之间起中介作用。此外，研究结果表明，态度构成了知识、环境关注和意图之间关系的基本机制。另一方面，道德规范证实了主观规范建构与消费意愿之间存在关系，道德规范塑造了主观规范与态度之间关系的根本机制，强调了道德价值观在伊朗消费文化中的深远影响。相比之下，新食物恐惧症对消费意愿没有显著影响，这表明伊朗人对饮食创新持开放态度。本研究通过确定扩展的计划行为理论成分对食用藻类或含藻类食物的决定的直接、间接和总影响，有助于该领域的理论进步。在实践中，本研究结果可以为新兴市场藻类食品的有效引进和推广策略提供指导。

Reminiscence theatre (RT), an applied drama technique, is an effective tool for improving health-related outcomes for older adults in clinical settings. However, no research has explored the potential for a food-themed RT intervention to improve the nutrition, health and wellbeing of this population. Therefore, the current study explored the feasibility and acceptability of such an intervention – the CURTAIN intervention – in residential care-homes. Two care-homes, their residents and staff were recruited to a cluster randomised crossover feasibility study with post-hoc interviews. Over two months, participants (n = 42) took part in the CURTAIN activity and a control activity before consuming their lunch, with momentary hunger, activity/meal enjoyment, and food intake measured around each activity. Continuation to a full-scale trial was assessed against progression criteria for data-collection-sheet completion and residents' enjoyment of the intervention. The intervention was highly enjoyed by residents (median score = 8/10), with only 1% of data-collection cells blank. Attrition rate was 5% and preliminary data suggest CURTAIN has the potential to improve residents’ appetite and energy intake. Aspects of evaluation design and recruitment strategy to optimise sample diversity require some amendments; however, overall, the CURTAIN intervention is feasible and acceptable to care-home residents and staff, and a full intervention evaluation is warranted.

怀旧戏剧（RT）是一种应用戏剧技术，是改善临床环境中老年人健康相关结果的有效工具。然而，没有研究探索以食物为主题的RT干预的潜力，以改善这一人群的营养、健康和福祉。因此，本研究探讨了在安老院舍实施幕式干预的可行性和可接受性。两家护理院，他们的居民和工作人员被招募到一个随机交叉可行性研究与事后访谈。在两个多月的时间里，参与者（n=42）在吃午餐前参加了CURTAIN活动和对照活动，测量了每次活动前后的短暂饥饿感、活动/用餐享受和食物摄入量。根据数据收集表的完成情况和居民对干预的享受程度的进展标准，对全面试验的继续进行了评估。居民非常喜欢干预（中位数得分= 8/10），只有1%的数据收集单元为空白。流失率为5%，初步数据表明，CURTAIN有可能改善居民的食欲和能量摄入。评估设计和招聘策略方面，以优化样本多样性需要一些修改；然而，总体而言，窗帘干预是可行的和可接受的养老院的居民和工作人员，并进行全面的干预评估是必要的。

Examinations of links between plant-based diets (e.g., vegetarian and vegan diets) and indices of physical and mental health have received increased attention in the scientific literature in recent years. However, there has been little to no published research examining predictors of plant-based diet choice. Researchers have suggested that plant-based diets could be linked to trauma for a variety of reasons, including the idea that trauma can increase the risk for mental illnesses, and plant-based diets may be adopted to self-medicate mental illness and promote recovery. The current study examined the link between trauma across the lifespan and experiences of intimate partner violence (IPV) with adherence to a plant-based diet. Participants were a nationally representative United States sample of 1665 individuals who completed self-report questionnaires. Consistent with hypotheses, bivariate correlations indicated that all measures of trauma were associated with an increased likelihood of being plant-based. Findings from a logistic regression analysis indicated those with a history of IPV were 2.31 times more likely to be plant-based, and those with any experience of trauma more broadly were 1.09 times more likely to be plant-based. These results suggest the importance of considering the role of trauma and victimization when examining links between plant-based diet and other outcomes and point to a number of possible avenues for additional investigation to better understand these associations.

近年来，对植物性饮食（如素食和纯素饮食）与身心健康指数之间联系的研究在科学文献中受到越来越多的关注。然而，几乎没有发表过研究植物性饮食选择的预测因素的研究。研究人员认为，植物性饮食可能与创伤有关，原因有很多，包括创伤会增加患精神疾病的风险，植物性饮食可能被用来自我治疗精神疾病，促进康复。目前的研究调查了一生中的创伤和亲密伴侣暴力（IPV）经历与坚持植物性饮食之间的联系。参与者是具有全国代表性的1665名美国人，他们完成了自我报告问卷。与假设一致，双变量相关性表明，所有创伤测量都与植物性饮食的可能性增加有关。逻辑回归分析的结果表明，有IPV病史的人以植物为基础的可能性是2.31倍，而那些有过更广泛创伤经历的人以植物为基础的可能性是1.09倍。这些结果表明，在检查植物性饮食与其他结果之间的联系时，考虑创伤和受害的作用是很重要的，并指出了一些可能的进一步调查途径，以更好地了解这些关联。

The current food systems and the dominating dietary patterns in most EU countries contribute to climate change and are not sustainable. Legumes have the potential to make consumption patterns more sustainable, especially if they come from local or organic production systems. Yet, legume consumption in Germany is low. Thus, this study aimed to increase legume consumption, understand consumer preferences for organic and local production in relation to the processing level, and provide marketing recommendations for different target groups. An online survey including an information display matrix was conducted with 1300 participants from Germany. Preferences for locally and organically produced lentils were identified by search depth and order and a multinomial logistic regression analysis. A latent class cluster analysis (LCA) identified five consumer segments relevant to legume consumption based on psychographics. Results showed a preference for local and organic lentils, regardless of the processing level of the product. Of the five consumer segments, two segments (accounting for 55 %) were rather price-sensitive with a low legume and high meat consumption. Another two segments (23 %) were sustainably-oriented and one segment had a strong preference for cooking. Concluding, there is a potential to market local and organic legumes, however, only for the sustainably-oriented consumers. Hence, for now, legumes remain a niche product in Germany. For a significant increase in legume consumption, also consumers’ awareness has to increase: for the environment, health, and the environmental impact of meat consumption.

目前大多数欧盟国家的粮食系统和主要饮食模式助长了气候变化，并且是不可持续的。豆类有可能使消费模式更具可持续性，特别是如果它们来自当地或有机生产系统。然而，德国的豆类消费量很低。因此，本研究旨在增加豆类消费，了解消费者对有机和本地生产的偏好与加工水平的关系，并为不同的目标群体提供营销建议。一项包括信息显示矩阵的在线调查对来自德国的1300名参与者进行了调查。通过搜索深度和顺序以及多项逻辑回归分析确定了对本地和有机扁豆的偏好。潜在类聚类分析（LCA）根据心理特征确定了与豆类消费相关的五个消费者群体。结果显示，无论产品的加工水平如何，人们都更喜欢本地和有机扁豆。在五个消费者群体中，有两个群体（占55%）对价格相当敏感，豆类消费低，肉类消费高。另外两个部分（23%）以可持续发展为导向，一个部分对烹饪有强烈的偏好。综上所述，本地有机豆科食品的销售是有潜力的，但只面向面向可持续发展的消费者。因此，目前豆类在德国仍然是一种小众产品。对于豆类消费的显著增加，消费者的意识也必须提高：对于环境、健康和肉类消费对环境的影响。

The ongoing obesity epidemic is an indicator that traditional efforts towards diet change are insufficient, and interventions focusing mainly on restrictions of unhealthy food are of limited success. Therefore, approaches targeting food preferences should be integral in counteracting the current epidemic. However, food preferences are affected by a multitude of factors and are usually resistant to changes later in life. Hence, we tested whether the food choices of preschool children can be changed by a child-appropriate, interactive, fairytale-like narrative. We used two interactive stories: the first (experimental) story was about how two protagonists of similar age as the participants saved their hometown from being drained of color with the help of magic fruits or vegetables, while the second (control) story consisted of a similar plot that did not mention food. In Experiment 1, we used a crossover design with a one-week baseline measurement. After the experimental stories, healthy food choices (i.e., pieces of fruit vs. cookies, sweets, or cake) increased significantly relative to the one-week baseline, whereas no change was observed after the control story. In preregistered Experiment 2, we replicated these results with vegetables as healthy options using a random control design and investigated the longevity of the effects. The food-story effect on vegetable choices was similar to fruits (Exp. 1) and lasted for two weeks. These findings demonstrate that appropriate narratives about food can have a strong and lasting effect on the healthy food choices of preschool children and might promote healthy food consumption if incorporated into nutrition education.

持续的肥胖流行病表明，改变饮食习惯的传统努力是不够的，主要侧重于限制不健康食品的干预措施成效有限。因此，针对食物偏好的方法应该是对抗当前流行病的组成部分。然而，食物偏好受到多种因素的影响，并且通常在以后的生活中不易改变。因此，我们测试了学龄前儿童的食物选择是否可以通过适合儿童的、互动的、童话般的叙述来改变。我们使用了两个互动故事：第一个（实验）故事是关于两个与参与者年龄相仿的主角如何借助神奇的水果或蔬菜拯救他们的家乡，而第二个（对照）故事包含一个类似的情节，但没有提到食物。在实验1中，我们使用了一周基线测量的交叉设计。在实验故事之后，健康食物的选择（即，水果片、饼干、糖果或蛋糕）相对于一周基线显著增加，而在对照故事之后没有观察到任何变化。在预注册的实验2中，我们使用随机对照设计将蔬菜作为健康选择来重复这些结果，并研究了效果的持久性。食物故事对蔬菜选择的影响与水果相似（实验1），并持续了两周。这些发现表明，适当的食物叙述可以对学龄前儿童的健康食品选择产生强烈而持久的影响，如果将其纳入营养教育，可能会促进健康食品的消费。

The increasing cultural diversity in the United States means more college students identify with racial and ethnic minority backgrounds and may experience acculturative stress. Emerging research has found an association between acculturative stress and maladaptive eating. However, these studies rarely consider other theoretical factors or confounders, and individual differences. Thus, the unique contribution of acculturative stress and the generalizability of previous findings remain unclear.

Objective

This cross-sectional study investigated the role of acculturative stress and self-construal (i.e., how individuals define themselves in relation to others in social environments) in maladaptive eating among female college students.

Method

Participants were 446 female young adults (M_age = 20.38, SD = 1.75; M_BMI = 23.42, SD = 4.62) who completed online questionnaires.

Results

Structural equation modeling results showed that acculturative stress was related to higher disinhibited eating even when accounting for traditional theoretical risk factors (i.e., body dissatisfaction, perceived sociocultural pressures on body image, and general stress) and potential confounders (i.e., age, BMI, SES, ethnic backgrounds, and birthplace). Furthermore, independent self-construal (i.e., when individuals see themselves as autonomous, prioritizing personal goals and uniqueness over social relationships) moderated this association. When independent self-construal was higher, the magnitude of the regression coefficient between acculturative stress and disinhibited eating was smaller.

Discussion

Given the increasing diversity within U.S. higher education, eating behavior theories should consider integrating acculturative stress to improve inclusiveness. College psychological services should tailor prevention and treatment strategies for maladaptive eating to address acculturative stress, while also promoting an environment that supports healthy, independent self-construal.

美国日益增长的文化多样性意味着更多的大学生认同种族和少数民族背景，并可能经历文化异化压力。新兴研究发现，异文化压力和饮食不良之间存在关联。然而，这些研究很少考虑其他理论因素或混杂因素，以及个体差异。因此，异文化压力的独特贡献和先前研究结果的普遍性仍不清楚。目的：本横断面研究探讨异文化压力和自我建构（即个体如何在社会环境中定义自己与他人的关系）在女大学生饮食适应不良中的作用。方法：参与者为446名年轻女性(Mage = 20.38, SD = 1.75；MBMI = 23.42, SD = 4.62)。结果：结构方程建模结果显示，即使考虑到传统的理论风险因素（即身体不满意、对身体形象的感知社会文化压力和一般压力）和潜在的混杂因素（即年龄、体重指数、社会经济地位、种族背景和出生地），异文化压力也与更高的去抑制性饮食有关。此外，独立的自我解释（即当个体认为自己是自主的，优先考虑个人目标和独特性而不是社会关系时）调节了这种关联。当独立自我解释水平越高时，异文化应激与去抑制性进食之间的回归系数越小。讨论：鉴于美国高等教育日益多样化，饮食行为理论应考虑整合异文化压力以提高包容性。大学心理服务部门应该针对饮食适应不良量身定制预防和治疗策略，以解决异文化压力，同时也要营造一个支持健康、独立的自我构建的环境。

As food choices are increasingly made in contexts such as online supermarkets, nudging has been extrapolated to the digital sphere. Digitalization poses unique opportunities to enhance the promotion of healthier food choices online: Digital nudges can be delivered “just-in-time” (JIT), in response to the initial selection of an unhealthy product. Furthermore, digital JIT nudges can be personalized to match user characteristics of behavioral relevance, such as one's food and cognitive processing preferences. We examined whether personalizing by user-matching digital JIT nudges on content (i.e., emphasizing health versus price) and/or type (i.e., a text-based versus an image-based nudge) would increase nudge effectiveness and healthier food purchases, and assessed psychological mechanisms potentially underlying these enhanced effects. In a 2 (Nudge Content: Non-personalized versus Personalized) by 2 (Nudge Type: Non-personalized versus Personalized) randomized controlled trial, 200 healthy participants completed an online grocery shopping task on a mock supermarket app in which they first selected products from 10 different categories, followed by a checkout screen where they could replace products in the shopping basket. Personalizing nudge type increased nudge effectiveness (i.e., the proportion of accepted nudges when choosing products from categories). Personalizing nudge content seemed to exert a delayed effect of increasing healthier product replacements prior to checkout. User perceptions of JIT nudges did not vary with personalization. However, regardless of personalization, all JIT nudging conditions had more final healthier food purchases and greater satisfaction with food choices compared to the control condition. Collectively, this pre-registered “proof-of-principle” study demonstrates that personalizing the content and type of digital JIT nudges yields small positive benefits on the healthiness of online food choices and attests to the utility of JIT interventions for health promotion.

随着人们越来越多地在网上超市等环境中选择食物，“助推”已经被推断到数字领域。数字化为加强在线推广更健康的食品选择提供了独特的机会：根据最初选择的不健康产品，可以“及时”提供数字推送。此外，数字JIT推动可以个性化，以匹配行为相关的用户特征，例如一个人的食物和认知加工偏好。我们研究了通过用户匹配的数字即时推送的个性化内容（即强调健康与价格）和/或类型（即基于文本的推送与基于图像的推送）是否会提高推送效果和更健康的食品购买，并评估了这些增强效果潜在的心理机制。在一项2（推动内容：非个性化vs个性化）* 2（推动类型：非个性化vs个性化）随机对照试验中，200名健康参与者在一个模拟超市应用程序上完成了一项在线杂货购物任务，他们首先从10个不同类别中选择产品，然后在结账屏幕上更换购物篮中的产品。个性化的轻推类型增加了轻推的有效性（即从类别中选择产品时接受轻推的比例）。个性化推送内容似乎发挥了一种延迟效应，即在结账前增加更健康的产品替代品。用户对JIT轻推的看法不随个性化而变化。然而，无论个性化如何，与控制条件相比，所有JIT推动条件下的最终健康食品购买量和对食品选择的满意度都更高。总的来说，这项预先注册的“原理验证”研究表明，个性化的数字JIT推送内容和类型对在线食品选择的健康产生了微小的积极效益，并证明了JIT干预对健康促进的效用。

Certain interoceptive hunger cues are caused by gut physiology. These interoceptive cues may have psychological consequences, namely an ability to enhance the desire to eat, which are independent of their physiological cause. Testing this idea is difficult because the physiological processes are normally linked to any consequence. In this preliminary report we attempted to induce an interoceptive hunger cue (a stomach rumble), to examine its psychological consequences independent from its physiological cause. In three online Studies (1–3), participants viewed images of food while listening to different sounds including quiet stomach rumbles and judged the source of the sound, and their desire to eat the depicted foods. In Studies 1–3, irrespective of when they last ate and their reported level of hunger, and relative to control sounds, stomach rumble sounds enhanced desire to eat depicted foods, especially when they were mislocalised to the participants’ own stomachs. In Study 1 49% of participants reported some degree of mislocalisation, 74% in Study 2, and 77% in Study 3. Overall, around 40% reported mimicry, where they felt that hearing the computer-generated stomach rumble sound induced the same in themselves. In Study 3 heart beat sounds were included. These too were mislocalised, and enhanced desire to eat depicted foods. In sum, this preliminary report suggests it may be possible to psychologically induce interoceptive cues, including one specific to hunger, and that these cues may then enhance food desire when mislocalised to self. In addition, the findings support the idea that interoceptive hunger cues may have associative properties that augment desire to eat.

某些内感受性饥饿信号是由肠道生理引起的。这些内感受性线索可能会产生心理上的影响，即增强食欲的能力，而这与生理原因无关。验证这一观点是困难的，因为生理过程通常与任何结果相关联。在这个初步报告中，我们试图诱导一个内感受性饥饿提示（胃的隆隆声），以检查其独立于其生理原因的心理后果。在三个在线研究（1-3）中，参与者一边观看食物图像，一边听不同的声音，包括安静的胃隆隆声，并判断声音的来源，以及他们吃描绘食物的欲望。在研究1-3中，不管他们最后一次吃东西是什么时候，也不管他们报告的饥饿程度是什么，相对于对照声音，胃的隆隆声增强了他们吃所描述食物的欲望，尤其是当这些声音被错误地定位在参与者自己的胃里时。在研究1中，49%的参与者报告了某种程度的定位错误，研究2中为74%，研究3中为77%。总的来说，大约40%的人表示会模仿，他们觉得听到电脑产生的胃隆隆声会让他们自己产生同样的模仿。在研究3中包括了心跳声。这些都是错误的本地化，并增强了人们对描绘食物的渴望。总之，这一初步报告表明，有可能从心理上诱导内感受性线索，包括一个特定于饥饿的线索，当这些线索被错误地定位到自我时，这些线索可能会增强对食物的渴望。此外，研究结果支持了内感受性饥饿线索可能具有增强食欲的联想特性的观点。
