Appetitive traits developed in infancy may influence dietary habits in later childhood. The impact of maternal eating behaviours (MEBs) and feeding practices remains unclear. This cross-sectional study examined the associations between MEBs, feeding practices, and appetitive traits of infants aged 1–6 months in Malaysia. A total of 256 mother-infant pairs were recruited from six government maternal and child health clinics in Kuala Lumpur and Putrajaya. Data were collected through self-administered questionnaires: the Dutch Eating Behaviour Questionnaire (DEBQ) to assess MEBs (emotional, external, and restrained eating); the Baby's Basic Needs Questionnaire (BBNQ) to evaluate feeding practices (feeding modes and feeding-to-soothe (FTS)); and the Baby Eating Behaviour Questionnaire (BEBQ) to measure infants' appetitive traits (food responsiveness, enjoyment of food, satiety responsiveness, slowness in eating, and general appetite). The mothers' mean age was 32.31 ± 4.45 years, and the infants' mean age was 3.73 ± 1.67 months. Food responsiveness of formula-fed infants (14.33 ± 4.82) was significantly lower than breastfed (17.99 ± 5.33). Restrained eating was significantly associated with higher satiety responsiveness (B = 0.206, 95 % CI = 0.022–0.099), and FTS was linked to increased food responsiveness (B = 0.334, 95 % CI = 0.116–0.241). These findings highlighted the associations between MEBs and FTS with infant appetitive traits. Longitudinal studies are needed to clarify these relationships and their long-term implications.
婴儿时期形成的食欲特征可能影响儿童后期的饮食习惯。产妇饮食行为(meb)和喂养方式的影响尚不清楚。本横断面研究检查了马来西亚1-6个月婴儿meb、喂养方法和食欲特征之间的关系。从吉隆坡和布城的六个政府妇幼保健诊所共招募了256对母婴。数据通过自我管理问卷收集:荷兰饮食行为问卷(DEBQ)评估meb(情绪性、外源性和克制性饮食);婴儿基本需求问卷(BBNQ),用于评估喂养方式(喂养方式和喂养安抚(FTS));以及婴儿饮食行为问卷(BEBQ)来测量婴儿的食欲特征(食物反应、食物享受、饱腹反应、进食缓慢和总体食欲)。母亲平均年龄32.31±4.45岁,婴儿平均年龄3.73±1.67个月。配方奶喂养婴儿的食物反应性(14.33±4.82)明显低于母乳喂养婴儿(17.99±5.33)。克制进食与高饱腹感反应显著相关(B = 0.206, 95% CI = 0.022-0.099), FTS与食物反应性增加相关(B = 0.334, 95% CI = 0.116-0.241)。这些发现强调了meb和FTS与婴儿食欲特征之间的联系。需要进行纵向研究来澄清这些关系及其长期影响。

Adolescents are increasingly moving away from the Mediterranean Diet (MD), raising concerns for their long-term health. Since adolescence is crucial for shaping eating habits, school-based interventions offer an opportunity to promote healthier choices. Nutrition and sensory education can influence food attitudes and behaviors, but their combined effects are not well understood. This study tested school-based nutrition and sensory education programs, alone or combined, with daily exposure to a healthy, unfamiliar snack, on Italian adolescents’ food knowledge, attitudes, and behaviour. A total of 197 students (aged 14–17) were assigned to one of four groups: Control, Nutrition, Sensory, or Nutrition and Sensory. Over four weeks, participants received targeted lessons and were offered a healthy snack each day. Data were collected at baseline, post-intervention, and at a two-month follow-up. Key outcomes included nutritional knowledge, adherence to the MD (KIDMED), food neophobia, picky eating, food choices, and acceptance of healthy snacks. Nutrition education improved nutritional knowledge and the ability to identify MD foods, with partial retention at follow-up. However, daily dietary habits showed little changes. Sensory education increased snack consumption and willingness to try unfamiliar foods. No significant changes were observed in food neophobia or picky eating. These findings highlight the value of integrating diverse, experience-based strategies into school settings to support the development of food knowledge and healthier food choices in adolescence.
青少年越来越多地放弃地中海饮食,这引起了对他们长期健康的关注。由于青少年时期是形成饮食习惯的关键时期,以学校为基础的干预措施提供了一个促进更健康选择的机会。营养和感官教育可以影响饮食态度和行为,但它们的综合作用尚未得到很好的理解。这项研究测试了以学校为基础的营养和感官教育计划,单独或结合,每天接触健康的,不熟悉的零食,对意大利青少年的食物知识,态度和行为。共有197名14-17岁的学生被分为四组:对照组、营养组、感官组和营养与感官组。在四周的时间里,参与者接受了有针对性的课程,并每天提供一份健康的零食。在基线、干预后和两个月的随访中收集数据。主要结果包括营养知识、对饮食指南(KIDMED)的依从性、新食物恐惧症、挑食、食物选择和对健康零食的接受程度。营养教育提高了营养知识和识别MD食物的能力,并在随访中部分保留。然而,日常饮食习惯几乎没有变化。感官教育增加了零食消费和尝试不熟悉食物的意愿。在新食物恐惧症或挑食方面没有观察到明显的变化。这些发现强调了将多样化的、基于经验的策略整合到学校环境中,以支持青少年食物知识和更健康食物选择的发展的价值。

With rising household incomes and increasing health awareness, consumers are exhibiting a growing preference for quality food with safety attributes. However, the extent to which consumers value food safety and quality attributes and how relevant information influences their purchasing behaviour has not been widely evaluated, particularly in developing countries such as Nepal. This study aims to analyse the preferences, willingness to pay and relative importance of various safety and quality attributes for making choice decisions among Nepalese milk consumers. This study employed a discrete choice experiment, which involved 401 participants in Kathmandu. A multinomial logit model, random parameter logit model and latent class model were utilised to examine preference heterogeneity, focusing on five key attributes: place of production, good manufacturing practices labelling, fat content, packaging material and price. The results indicated that all five attributes were significant in informing participants' purchase decisions. Consumers demonstrated a marked preference for good manufacturing practices labelled milk, with a willingness to pay a 42.78 % premium relative to conventional milk. Additionally, consumers expressed a positive valuation for domestically produced milk and milk packaged in plastic jars. We identified two distinct consumer segments, "Food safety-conscious consumers" and "Budget-conscious consumers". This study provides strong empirical evidence of the evolving preferences of Nepalese milk consumers towards food safety and quality attributes. In response to these evolving consumer demands, policymakers and dairy industry stakeholders should prioritise the production of milk that is safe, high in quality, and securely packaged, while also ensuring transparent and credible communication to build consumer trust.
随着家庭收入的增加和健康意识的增强,消费者对具有安全属性的优质食品的偏好日益增加。然而,消费者对食品安全和质量属性的重视程度以及相关信息对其购买行为的影响程度尚未得到广泛评估,特别是在尼泊尔等发展中国家。本研究旨在分析各种安全和质量属性对尼泊尔牛奶消费者做出选择决策的相对重要性。本研究采用离散选择实验,在加德满都有401名参与者参与。使用多项logit模型、随机参数logit模型和潜在类别模型来检验偏好异质性,重点关注五个关键属性:生产地、良好生产规范标签、脂肪含量、包装材料和价格。结果表明,这五个属性在告知参与者购买决策方面都很重要。消费者表现出对标有良好生产规范的牛奶的明显偏好,与传统牛奶相比,他们愿意支付42.78%的溢价。此外,消费者对国产牛奶和用塑料瓶包装的牛奶表示了积极的评价。我们确定了两个不同的消费者群体,“有食品安全意识的消费者”和“有预算意识的消费者”。本研究为尼泊尔牛奶消费者对食品安全和质量属性的偏好演变提供了强有力的经验证据。为了应对这些不断变化的消费者需求,政策制定者和乳制品行业利益相关者应优先考虑生产安全、高质量和包装美观的牛奶,同时确保透明和可信的沟通,以建立消费者的信任。

Appetite self-regulation (ASR) among children is thought to have a fundamental role in shaping the development of healthy eating behaviors, dietary intake, and growth during childhood. Parallel to developmental frameworks for understanding “general” self-regulation among children, ASR has been described as involving children's use of “top-down” cognitive processes to moderate “bottom-up” biological drives around food approach and avoidance in the interest of achieving desired eating behaviors or outcomes. Whereas bottom-up ASR processes during early childhood are well characterized, particularly in the context of dysregulation and obesity risk, the role of top-down ASR processes in the development of healthy eating behaviors is virtually unstudied. The purpose of this narrative review is to bring together diverse research literatures in developmental psychology, food parenting, and ingestive behavior to articulate a role for top-down ASR in the development of healthy eating behaviors in early childhood and highlight putative socialization influences. We draw from a large literature on executive functioning in children to articulate how top-down ASR may be recruited in the service of achieving desired eating outcomes and draw from the developmental literature to highlight the potential avenues of socialization for top-down ASR processes.
儿童的食欲自我调节(ASR)被认为在塑造儿童健康饮食行为、饮食摄入和成长的发展中起着重要作用。与理解儿童“一般”自我调节的发展框架平行,ASR被描述为涉及儿童使用“自上而下”的认知过程来调节“自下而上”的生物驱动,围绕食物方法和避免,以实现预期的饮食行为或结果。儿童早期自下而上的ASR过程被很好地描述,特别是在失调和肥胖风险的背景下,自上而下的ASR过程在健康饮食行为发展中的作用几乎没有研究。这篇叙述性综述的目的是汇集发展心理学、食物养育和摄食行为方面的各种研究文献,阐明自上而下的ASR在幼儿健康饮食行为发展中的作用,并强调可能的社会化影响。我们借鉴了大量关于儿童执行功能的文献,阐明了自上而下的ASR如何被用于实现预期的饮食结果,并借鉴了发展文献,强调了自上而下的ASR过程的社会化的潜在途径。

We investigated the potential of OCOsense™ smart glasses to monitor eating and support behaviour change in everyday life. Twenty-three volunteers (14 women, 7 men and 2 non-binary individuals) wore the glasses for 7 h/day, at least five days/week for three weeks. To establish a baseline, in week one, participants wore the glasses with minimal intervention; in week two, they annotated each eating event and photographed their food to evaluate detection accuracy. In week three, participants responded to real-time notifications confirming whether eating was occurring when sensed by the glasses, and received haptic feedback (i.e., glasses vibration) prompting them to either chew more slowly, chew more per mouthful or take longer pauses between bites. Based on sensed chewing, the glasses algorithm detected 476/498 eating events logged in week two (F1-score 0.89), and 528/548 real-time events in week three (F1-score 0.91). To assess food detection accuracy, 598 images (1036 items) were analysed by an algorithm and compared to manual inspection. The algorithm correctly identified 919/1036 items. Compared to baseline, those aiming to change their behaviour: 1) reduced chewing rate (1.63–1.57 chews/sec), while others increased slightly (1.70–1.73); 2) increased chews per bite (22.0–22.8), which declined in others (22.8–19.5); and 3) lengthened breaks between bite (4.69–5.33 s), while others shortened theirs (5.16–4.85 s). Overall, this study demonstrates that OCOsense glasses can detect when and what people eat in everyday life and that feedback delivered by the glasses has the potential to support behaviour change.
我们调查了OCOsense™智能眼镜在日常生活中监测饮食和支持行为改变方面的潜力。23名志愿者(14名女性,7名男性和2名非二元个体)每天戴眼镜7小时,每周至少5天,持续三周。为了建立一个基线,在第一周,参与者在最少干预的情况下戴眼镜;在第二周,他们对每个进食事件进行注释,并拍摄食物以评估检测的准确性。在第三周,参与者对实时通知做出反应,确认当眼镜感知到是否正在进食时,并收到触觉反馈(即眼镜振动),提示他们要么咀嚼得更慢,每一口咀嚼更多,要么在咬之间停顿更长时间。基于感知咀嚼,眼镜算法检测到第二周记录的476/498个进食事件(f1得分为0.89),第三周记录的528/548个实时事件(f1得分为0.91)。为了评估食品检测的准确性,通过算法分析了598张图像(1036个项目),并与人工检测进行了比较。该算法正确识别了919/1036个项目。与基线相比,那些旨在改变自己行为的人:1)咀嚼速度降低(1.63到1.57次/秒),而其他人则略有增加(1.70到1.73次/秒);2)每一口咀嚼量增加(22.0到22.8),其他咀嚼量下降(22.8到19.5);3)延长了两次咬之间的休息时间(4.69秒到5.33秒),而其他人则缩短了他们的时间(5.16秒到4.85秒)。总的来说,这项研究表明,OCOsense眼镜可以检测人们在日常生活中什么时候吃什么,眼镜提供的反馈有可能支持行为改变。

Purpose

The International Complementary Feeding Evaluation tool (ICFET) is a new tool that provides a standardised description of caregiver feeding and child eating behaviour and diet in young children. It is designed to be relevant to undernutrition in low- and-middle-income countries (LMICs) and to be valid in multiple languages. This paper aims to describe the full content of the ICFET and its performance in various settings, cross-sectionally and longitudinally.

Method

ICFETs were completed by parents of 473 children aged 6–24 months in the UK, Kenya, Pakistan, and Guatemala. Repeated ICFETs were obtained for 62 children starting treatment for moderate acute malnutrition (MAM) in Kenya and Pakistan.

Findings

Solids were started much earlier in the UK than other countries; in Kenya and Pakistan self-feeding was less, and force feeding more common than in Guatemala and the UK. In the LMIC samples only 23 % children were eating foods from 5/8 of the recommended food groups daily. In the MAM treatment centres, Avidity was low: Kenya mean Z scores (SD) −1.76 (0.9); Pakistan −2.79 (0.9); and food refusal high: Kenya 0.77 (1.3), Pakistan 1.53 (0.9) compared to healthy UK infants; both showed moderate to good stability over time (Kenya Avidity Spearman's r = 0.517, p = 0.023 Refusal r = 0.557, p = 0.013; Pakistan Avidity r = 0.959, p < 0.001; Refusal 0.462 p = 0.002), suggesting that they are capturing enduring appetitive characteristics.

Conclusions

The ICFET provides valid eating and feeding behaviour measures which track within children over time, as well as a range of useful contextual measures of diet in the complementary feeding period.
目的:国际辅食评估工具(ICFET)是一种新的工具,它提供了幼儿照顾者喂养和儿童饮食行为和饮食的标准化描述。它旨在与低收入和中等收入国家(LMICs)的营养不良相关,并以多种语言有效。本文旨在描述ICFET的全部内容及其在各种设置下的性能,横截面和纵向。方法:由来自英国、肯尼亚、巴基斯坦和危地马拉的473名6-24月龄儿童的父母完成icfet。在肯尼亚和巴基斯坦对62名开始治疗中度急性营养不良(MAM)的儿童进行了重复的icfet。研究发现:英国的固体食品起步比其他国家早得多;与危地马拉和英国相比,肯尼亚和巴基斯坦的自我喂养较少,而强迫喂养更为普遍。在低收入和中等收入国家的样本中,只有23%的儿童每天食用推荐食物组中5/8的食物。在MAM治疗中心,贪婪度较低:肯尼亚平均Z评分(SD) -1.76 (0.9);巴基斯坦-2.79 (0.9);拒食率高:与健康的英国婴儿相比,肯尼亚的拒食率为0.77(1.3),巴基斯坦为1.53(0.9),这表明他们正在捕捉持久的食欲特征;随着时间的推移,两者都表现出中等到良好的稳定性(肯尼亚的食欲斯皮尔曼r= 0.517, p= 0.023;拒绝的r= 0.557, p=0.013;巴基斯坦的食欲r=0.959, p)。结论:ICFET提供了有效的饮食和喂养行为测量,可以长期跟踪儿童,以及一系列有用的补充喂养期间饮食的背景测量。

Adverse and positive childhood experiences (ACEs and PCEs, respectively) are known to influence various health-related outcomes in adulthood, including eating behaviors. Emotional eating is considered a maladaptive eating style, whereas intuitive eating is perceived as an adaptive one. Understanding how ACEs and PCEs relate to these eating styles could inform targeted interventions. This study investigated the relationship between the types of ACEs and PCEs and eating styles (emotional and intuitive eating) among a national sample of Polish adults (n = 2231). ACEs were assessed using the Adverse Childhood Experiences Questionnaire and PCEs using the Benevolent Childhood Experiences Scale. The two eating styles were also assessed: maladaptive (emotional eating) via the Three-Factor Eating Questionnaire (TFEQ-13) and adaptive (intuitive eating) via the Intuitive Eating Scale-2 (IES-2). Network analysis revealed that emotional eating was positively associated with three ACEs: sexual abuse, unmet basic needs (e.g., access to food) and a lack of family love. However, emotional eating style was not associated with any PCEs. Intuitive eating was positively associated with three PCEs: comforting beliefs, fun activities, and self-acceptance. Similarly, intuitive eating was not associated with any ACEs. Body mass index (BMI) was positively associated with emotional eating and negatively associated with intuitive eating. Our findings suggest that PCEs and ACEs are independent predictors of opposing eating styles in adulthood. The results of this study can contribute to the development of effective interventions to promote the physical and mental well-being of adults.
众所周知,不良和积极的童年经历(分别为ace和pce)会影响成年后的各种健康相关结果,包括饮食行为。情绪化饮食被认为是一种不适应的饮食方式,而直觉饮食被认为是一种适应的饮食方式。了解ace和pce与这些饮食方式的关系可以为有针对性的干预提供信息。本研究调查了波兰成年人(n = 2231)的ace和pce类型与饮食方式(情绪化和直觉性饮食)之间的关系。不良童年经历问卷评估不良童年经历,善意童年经历量表评估不良童年经历。对两种饮食方式进行了评估:通过三因素饮食问卷(TFEQ-13)评估了不适应饮食(情绪饮食),通过直观饮食量表-2 (IES-2)评估了适应性饮食(直觉饮食)。网络分析显示,情绪化进食与三个ace呈正相关:性虐待、未满足的基本需求(例如,获取食物)和缺乏家庭爱。然而,情绪化饮食方式与任何pce无关。直觉性饮食与三种pce呈正相关:安慰的信念、有趣的活动和自我接受。同样,直觉性饮食与ace无关。身体质量指数(BMI)与情绪性饮食呈正相关,与直觉性饮食负相关。我们的研究结果表明,pce和ace是成年期相反饮食方式的独立预测因素。本研究的结果有助于开发有效的干预措施,以促进成年人的身心健康。

Population diets need to become healthier and more sustainable to limit their negative effects on health and environment. This study assessed the effect of a positioning intervention, in isolation and in combination with a labelling intervention, on the a) healthiness and b) environmental sustainability of food choices in an experimental online supermarket. Participants (n = 2220) were randomly assigned to one of five trials groups (control; healthier items shown earlier (“health position”); health position & nutri-score labels; environmentally sustainable products shown earlier (“eco position”); eco position & ecolabels) and completed a shopping task in an experimental online supermarket. Linear regressions showed that compared to control, mean scaled nutri-scores of shopping baskets were significantly lower (healthier) for health position (−2.30; 95 %CI: −3.07, −1.52) and health position & labels (−2.50; 95 %CI: −3.28, −1.72), with no significant difference between health position and health position & labels (−0.20; 95 %CI: −0.66, 0.25). The mean eco scores of shopping baskets were significantly reduced (more sustainable) for eco position (−24 %; 95 %CIs: −15 %, −31 %) and eco position & labels (−30 %; 95 % CIs: −22 %, 37 %) compared to control. The eco position & labels group had significantly lower mean eco scores (−8 %; 95 % CIs: −2 %, −14 %) compared to eco position. The positioning intervention improved health and environmental sustainability of food selections in an experimental online supermarket, with less robust evidence for a small additional effect of adding labels. There was no suggestion that adding labels that potentially make the positioning intervention more salient had any backfire effects.
人口饮食需要变得更健康和更可持续,以限制其对健康和环境的负面影响。本研究评估了定位干预(单独或与标签干预相结合)对实验性在线超市食品选择的a)健康和b)环境可持续性的影响。参与者(n=2220)被随机分配到五个试验组中的一个(对照组;较早显示的健康项目(“健康位置”);健康状况和营养评分标签;前面显示的环境可持续产品(“生态位置”);生态定位和生态标签),并完成了一个实验性的网上超市购物任务。线性回归显示,与对照相比,健康位置(-2.30;95%CI: -3.07, -1.52)和健康位置&标签(-2.50;95%CI: -3.28, -1.72)的购物篮平均营养评分显著降低(更健康),健康位置和健康位置&标签之间无显著差异(-0.20;95%CI: -0.66, 0.25)。与对照组相比,生态位置(-24%;95% ci: -15%, -31%)和生态位置和标签(-30%;95% ci: -22%, 37%)的购物篮平均生态得分显著降低(更具可持续性)。与生态位置相比,生态位置和标签组的平均生态得分明显较低(-8%;95% ci: -2%, -14%)。在一个实验性的网上超市中,定位干预改善了食品选择的健康和环境可持续性,而没有足够的证据表明添加标签会产生小的额外效果。没有迹象表明,添加可能使定位干预更加突出的标签会产生任何适得其反的效果。
