Weight discrimination is associated with deleterious health outcomes, including high stress and disordered eating. According to the rejection-identification model, people who perceive such group-based discrimination respond by identifying more strongly with their stigmatized group, which can attenuate negative consequences of discrimination. However, some research shows that these protective benefits may not exist in the weight domain. Here, we examined whether perceived weight discrimination predicts identifying as “fat,” and whether that increased identification protects against negative consequences of discrimination for health. In a larger study, U.S. adults who reported considering themselves “to be overweight” (N = 1725) reported on their perceived weight-based discrimination, fat-group identification, stress, and eating behaviors (i.e., uncontrolled eating, emotional eating, and restrained eating). We tested whether fat-group identification mediated the associations of perceived discrimination to stress and eating. Results showed that perceiving weight discrimination was associated with greater fat-group identification, which in turn was associated with more stress, uncontrolled eating, and emotional eating. These findings suggest that identifying as “fat” in the face of weight discrimination may not reduce subsequent stress or unhealthy eating patterns. As such, in contrast to prior research on the rejection-identification model that suggests identifying with one's group is protective for other identities, “fat” as an identity may not provide the same psychological and physical health benefits.
体重歧视与有害健康的结果有关,包括高压力和饮食失调。根据 "拒绝-认同 "模型,感受到这种基于群体的歧视的人的反应是更强烈地认同他们所鄙视的群体,这可以减轻歧视的负面影响。然而,一些研究表明,这些保护性益处在体重领域可能并不存在。在此,我们研究了感知到的体重歧视是否会预测对 "胖子 "的认同,以及这种认同的增强是否会保护健康免受歧视的负面影响。在一项更大规模的研究中,自称 "超重 "的美国成年人(1725 人)报告了他们感知到的体重歧视、脂肪群体认同、压力和饮食行为(即无节制饮食、情绪化饮食和节制饮食)。我们测试了脂肪群体认同是否对感知到的歧视与压力和进食之间的关联起到了中介作用。结果显示,感知到的体重歧视与更大的脂肪群体认同有关,而更大的脂肪群体认同又与更大的压力、失控饮食和情绪化饮食有关。这些研究结果表明,在面对体重歧视时认定自己是 "胖子",可能不会减少随后的压力或不健康的饮食模式。因此,与之前关于拒绝-认同模型的研究相反,"胖 "作为一种身份可能不会带来同样的心理和生理健康益处。

Children are often exposed to unhealthy outdoor food advertisements during the school commute. This exposure can have negative public health consequences given childhood weight gain has been linked to the marketing of energy-dense and nutrient-poor foods. This study aimed to explore schoolchildren's lived experiences and attitudes towards outdoor advertising surrounding their schools. Seven focus groups with children aged 10–16 years (n = 47) attending schools located in areas with high densities of unhealthy outdoor advertising were conducted in Perth, Western Australia, between July and October 2023. Study participants were aware of outdoor advertising of unhealthy food and beverages near their school, with many reporting that it impacted their food preferences and diet. Many participants felt it was unethical to advertise unhealthy food and beverages around schools and strongly supported restricting alcohol advertising within school precincts. Participants suggested a range of strategies to manage outdoor advertising of unhealthy food and beverages, including banning advertisements on public transport. These findings have the potential to impact State and local government policies affecting children's exposure to unhealthy outdoor advertising, serving as a crucial strategy in the fight against childhood obesity and the harmful effects of alcohol.
孩子们在上学的路上经常接触到不健康的户外食品广告。鉴于儿童期体重增加与高能量和低营养食品的营销有关,这种接触可能对公共卫生产生负面影响。本研究旨在探讨学童对学校周边户外广告的生活经验及态度。在2023年7月至10月期间,在西澳大利亚州珀斯对7名10至16岁儿童(n=47)进行了焦点小组调查,这些儿童就读于不健康户外广告密集地区的学校。研究参与者意识到学校附近有不健康食品和饮料的户外广告,许多人报告说这影响了他们的食物偏好和饮食。许多与会者认为在学校周围宣传不健康食品和饮料是不道德的,并强烈支持在学校范围内限制酒类广告。与会者提出了一系列管理不健康食品和饮料户外广告的战略,包括禁止在公共交通工具上投放广告。这些发现有可能影响州和地方政府的政策,影响儿童接触不健康的户外广告,作为对抗儿童肥胖和减少儿童酒精摄入量的关键战略。

Results regarding the impact of bariatric surgery (BS) on food choices are inconsistent between studies based on self-reported questionnaires, and those using direct measurements. Moreover, the determinants of the modifications of food choices after BS, if any, are still poorly understood. This study compared food choices, food liking, microstructure of ingestive behavior and sensory perceptions between women who had BS in the last 18 months (BS group, n = 19; Roux-en-Y gastric bypass or sleeve gastrectomy) and women with BMI ≥35 kg m−2 (OB group, n = 17) in ecological conditions and explored the associations of food choices with sensory perceptions and food liking.

Methods

Food choices and liking were assessed using a standardized ad-libitum buffet. Taste Strips and Scratch and Sniff cards were used to measure sensory perceptions. Microstructure of ingestive behavior of solid foods was studied using video recordings while eating the ad-libitum buffet.

Results

Women in the BS group consumed half as many calories at the buffet (p = .004) as the OB group, taking smaller bites (7.5 ± 1.9 vs 9.7 ± 2.4 g/bite; p = .020) at a slower ingestion rate (2.1 ± .7 vs 3.8 ± 1.1 bites/min; p = .035). No differences were found in food choices, food liking and sensory perceptions. In the BS group, consuming very high energy density foods was negatively associated with salt taste perceived intensity (p = .021) and the liking of fruits and vegetables (p = .045).

Conclusion

This is the first study that assessed the microstructure of ingestive behavior of solid foods in a population who has had BS. Ingestive behavior, but not food choices or liking, were different in women who had BS compared to women with obesity who did not have BS. However, only women with BS had their food choices associated with gustatory perceptions and food liking. Whether taste perceptions or types of food appreciations should be used as healthy-food choice predictors following BS should be further explored in future research.
关于减肥手术(BS)对食物选择的影响,基于自我报告问卷的研究和使用直接测量的研究结果不一致。此外,在BS后改变食物选择的决定因素,如果有的话,仍然知之甚少。本研究比较了过去18个月内患有BS的女性的食物选择、食物喜好、摄食行为微观结构和感官知觉(BS组,n=19;Roux-en-Y胃旁路或袖式胃切除术)和BMI≥35 kg的女性。m-2 (OB组,n=17)在生态条件下,探索食物选择与感官知觉和食物喜好的关系。方法:采用标准化自助餐自助餐对食物选择和喜爱程度进行评估。味觉条和抓挠和嗅嗅卡片被用来测量感官知觉。利用录像研究了进食自助餐时固体食物摄食行为的微观结构。结果:BS组的女性在自助餐中消耗的卡路里是OB组的一半(p= 0.004),每一口摄入的卡路里更少(7.5±1.9 g vs 9.7±2.4 g);P = 0.020),食入速度较慢(2.1±0.7 vs 3.8±1.1咬/min);p =) 1。03 =。在食物选择、食物喜好和感官知觉方面没有发现差异。在BS组中,食用能量密度非常高的食物与盐味感知强度(p= 0.021)和对水果和蔬菜的喜爱(p= 0.045)呈负相关。结论:这是第一项评估BS患者固体食物摄取行为微观结构的研究。患有BS的女性与没有BS的肥胖女性相比,饮食行为(而不是食物选择或喜好)有所不同。然而,只有患有BS的女性的食物选择与味觉感知和喜欢食物有关。味觉感知或食物欣赏类型是否可以作为BS后健康食品选择的预测因素,有待于未来的研究进一步探讨。

Mandatory calorie labelling on restaurant menus has been implemented in several Western countries. The purpose of the present study was to examine direct and indirect effects of the exposure to calorie information on menus on body-related shame, guilt, and hubristic pride. Self-compassion was examined as a moderator, and self-objectification was examined as a mediator. Men and women (N = 359, mean age = 42 years) were recruited on Prolific for a study examining “self-perceptions and menu choices”. Participants were randomly assigned to view a menu with or without calorie information and select a hypothetical meal. Exposure to calories on menus statistically significantly predicted higher body-related shame, but not body-related guilt or body-related hubristic pride. Self-objectification did not mediate the relationship between exposure to calories on menus and body-related shame, guilt, or hubristic pride. Self-compassion moderated the relationship between exposure to calories on menus and body-related shame. Overall, individuals who scored low on self-compassion experienced higher body-related shame after exposure to a restaurant menu with calories. These findings outline potential harmful effects of mandatory calorie labelling that should be taken into account in the mandating and evaluation of such policies.
一些西方国家已经开始在餐厅菜单上强制标注卡路里。本研究的目的是考察菜单上的卡路里信息对与身体相关的羞耻感、负罪感和自大自豪感的直接和间接影响。研究将自我同情作为调节因子,将自我物化作为中介因子。我们在 Prolific 网站上招募了男性和女性(359 人,平均年龄 42 岁)参加一项名为 "自我认知与菜单选择 "的研究。参与者被随机分配查看有或没有卡路里信息的菜单,并选择一份假定的膳食。从统计学角度看,暴露于菜单上的卡路里信息会显著增加与身体有关的羞耻感,但不会增加与身体有关的内疚感或与身体有关的自负感。自我客体化并不能调节暴露于菜单上的卡路里与身体相关的羞耻感、内疚感或自负自豪感之间的关系。自我同情调节了暴露于菜单上的卡路里与身体相关羞耻感之间的关系。总体而言,自我同情得分较低的人在接触到含有卡路里的餐厅菜单后,与身体相关的羞耻感较高。这些研究结果概述了强制性卡路里标签可能产生的有害影响,在制定和评估此类政策时应考虑到这些影响。

The interplay between egoistic and altruistic values, self-identity, and ethical behaviors remains underexplored, despite its significance in ethical consumption. This study investigates these dynamics by developing and testing the Value-Identity-Behavior model using a robust dataset of 3023 participants from three leading fairtrade markets in Europe: the U.K., France, and Germany. Our findings reveal that self-identity positively influences willingness to pay (WTP) for fairtrade products, as consumers are more inclined to pay a premium when these products align with their self-concept. Both altruistic and egoistic values shape self-identity, although their impacts differ. Specifically, egoistic values such as monetary, visual, and functional considerations negatively affect WTP, while sensory and altruistic values enhance it. Additionally, egoistic values uniformly moderate the relationship between self-identity and ethical behaviors. Interestingly, altruistic values exert a negative moderating effect, suggesting that when altruistic values are dominant, self-identity expression becomes less critical for ethical purchasing decisions. The study concludes with theoretical insights and practical recommendations for promoting fairtrade products.
利己主义和利他主义价值观、自我认同和道德行为之间的相互作用,尽管在道德消费中具有重要意义,但仍未得到充分探讨。本研究通过开发和测试价值-身份-行为模型来调查这些动态,该模型使用了来自欧洲三个主要公平贸易市场(英国、法国和德国)的3023名参与者的强大数据集。我们的研究结果显示,自我认同正向影响公平贸易产品的支付意愿(WTP),因为当这些产品与消费者的自我概念一致时,消费者更倾向于支付溢价。利他主义和利己主义价值观都塑造了自我认同,尽管它们的影响不同。具体来说,利己主义价值观,如金钱、视觉和功能方面的考虑,会对WTP产生负面影响,而感官和利他主义价值观则会增强WTP。此外,利己主义价值观对自我同一性与伦理行为的关系具有一致的调节作用。有趣的是,利他主义价值观发挥负向调节作用,这表明当利他主义价值观占主导地位时,自我认同表达对道德购买决策的重要性降低。本研究总结了促进公平贸易产品的理论见解和实践建议。

This study investigates the role of emotions in predicting sustainable food purchase intentions. A national representative sample from Norway (N = 785) was randomly assigned to rate their emotional response to specific food categories: livestock, capture fishery, aquaculture, and hunting. Emotional responses to each food category were of moderate intensity but there were no significant differences between specific animal-sourced foods. Findings from a series of regression analyses showed that egoistic values positively predict the intensity of positive and negative emotions for all food categories. Additionally, it was shown that individual differences in biospheric values (when strong) and hedonic values (when weak) predicted stronger negative emotions. Further analysis showed that negative emotions are the most consistent predictor of willingness to pay for sustainable animal-sourced food. These findings suggest that negative emotions can potentially be leveraged to enhance sustainable animal-sourced food consumption intentions.

Parental feeding practices are associated with children's eating, but little is known about how childcare staff feeding practices relate to children's eating. The study examined the associations between childcare staff feeding practices and children's willingness-to-try-new-foods. Participants included children (n = 460), ages 3–5 years, and childcare staff (n = 91) recruited from 51 childcare centers in 10 Maryland counties. Feeding practices were measured using the Comprehensive Feeding Practices Questionnaire (CFPQ) adapted to the childcare setting. Children's willingness-to-try-new-foods was assessed using a food tasting activity administered in the childcare centers. Confirmatory and exploratory factor analyses were used to evaluate the factor structure of the CFPQ applied to childcare staff, and to identify modified factor structures. Logistic regressions assessed the association between childcare staff feeding practices and children's willingness-to-try-new-foods (categorized as high vs. low). Among this sample, a revised 7-factor, 32-item model, including encourage balance and variety, environment, healthy eating guidance, indulgent, monitoring, pressure, and restriction for health was identified. Children exposed to more indulgent feeding practices in the classroom had 2.13 (95% CI: 1.04, 4.37) times the odds of demonstrating high willingness-to-try-new-foods compared to children exposed to less frequent use of this feeding practice, with no associations among other feeding practices.

父母的喂养方式与儿童的饮食有关,但托儿所员工的喂养方式与儿童饮食的关系却鲜为人知。本研究探讨了保育员喂养方式与儿童尝试新食物的意愿之间的关系。参与者包括从马里兰州 10 个县 51 个托儿所招募的 3-5 岁儿童(460 人)和托儿所员工(91 人)。采用根据托儿所环境改编的 "综合喂养实践问卷"(CFPQ)对喂养实践进行测量。通过在托儿所开展的食物品尝活动,对儿童尝试新食物的意愿进行了评估。我们使用了确认性和探索性因素分析来评估适用于托儿所员工的 CFPQ 的因素结构,并确定修改后的因素结构。逻辑回归评估了保育员的喂养方式与儿童尝试新食品的意愿(分为高与低两类)之间的关联。在这一样本中,确定了一个经过修订的 7 个因素、32 个项目的模型,包括鼓励平衡和多样化、环境、健康饮食指导、放纵、监督、压力和健康限制。与较少使用这种喂养方式的儿童相比,在课堂上接触较多放纵喂养方式的儿童表现出尝试新食物的高意愿的几率是后者的2.13倍(95% CI:1.04,4.37),而其他喂养方式之间没有关联。了解托儿所员工喂养方式的驱动机制及其与儿童饮食行为的关系,可以为促进幼儿健康饮食行为的干预措施提供依据。

This study aimed to explore Singaporean fathers' perceived influence over their children's eating habits. 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.
本研究旨在探讨新加坡父亲对孩子饮食习惯的感知影响。采用描述性定性研究设计。采用方便抽样的方法,在某三级公立医院儿科普通门诊招募3 ~ 21岁儿童的父亲。数据收集时间为2023年9月至2024年1月。对15位父亲进行了访谈,直到数据饱和。采用半结构化访谈指南进行虚拟访谈,采用专题分析进行数据分析。确定了三个主题和九个次级主题。三个主题是:(1)奠定良好的基础;(2)环境塑造观点;(3)未来行为改变的动因。父亲们认为自己为孩子的饮食习惯打下了良好的基础,从而影响了孩子的饮食习惯,而他们的观点则受到自己所处环境的影响,如时间不够和性别角色。父亲们发现了可以引发他们未来行为改变的因素,从而更好地影响孩子的饮食习惯。这些发现为父亲的观念提供了细致入微的见解,有助于未来发展针对父亲的干预措施,以增强他们在促进子女良好饮食习惯方面的影响力。保健专业人员可通过在临床环境中向母亲和父亲提供有关儿童健康营养的健康教育,鼓励父亲参与。医疗保健专业人员也可以组织动手活动,教父亲如何探索食物和营养,让他们和孩子一起参加。

Health information, particularly about nutrition, has flourished on social media in recent years. However, these claims often lack proper scrutiny enhancing the risk of misinformation. Nutrition misinformation on social media can originate from various sources including influencers, celebrities, and (freelance) journalists, who often have substantial reach. We conducted a between-subjects experiment, manipulating presence of misinformation and source type (influencer/celebrity/journalist), among N = 480 youth aged 16–22 years. We investigated how nutrition misinformation affects their nutrition (mis)beliefs and dieting. We also tested the moderating role of participants' issue involvement and the mediating role of the sources' perceived expertise. We found that youth remained largely unaffected by nutrition misinformation. However, perceived source expertise acted as a heuristic cue to determine trust in an unknown health content creator. This perceived expertise, in turn, increased perceived healthiness of food products mentioned by the ‘expert’ content creator regardless of misinformation exposure.
近年来,健康信息,尤其是营养信息,在社交媒体上蓬勃发展。然而,这些说法往往缺乏适当的审查,增加了错误信息的风险。社交媒体上的营养错误信息可以来自各种来源,包括有影响力的人、名人和(自由撰稿人)记者,他们通常有很大的影响力。我们进行了一项被试之间的实验,在N = 480名年龄在16至22岁之间的年轻人中,操纵错误信息的存在和来源类型(影响者/名人/记者)。我们调查了营养错误信息如何影响他们的营养(错误)信念和节食。我们还测试了被试的问题介入的调节作用和来源的感知专业知识的中介作用。我们发现年轻人基本上不受营养错误信息的影响。然而,感知源专业知识充当启发式线索,以确定对未知健康内容创建者的信任。这种感知到的专业知识反过来又增加了“专家”内容创建者所提到的食品的健康感知,而不管错误信息的曝光。

Healthy diets are crucial for maintaining overall well-being and reducing risk of health complications. 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.
健康饮食对于维持整体健康和减少健康并发症的风险至关重要。视觉提示和启动是促进更健康的消费习惯的流行隐性推动技术。本综述和荟萃分析是根据PRISMA指南进行和报告的。它旨在评估这些提示和启动对推动消费相关行为的有效性。对六个电子数据库进行了全面搜索,以进行关于在食品/饮料消费中使用非基于营销的视觉线索/启动物的实验研究。纳入了来自52篇文章的66项研究,结果将205项比较分为7组进行单独分析:(1)健康食品和(2)与身体相关的推动,以及(3)不健康食品和(4)与身体相关的推动,与中性对照;(5)混合健康食品和(6)与身体相关的比较;(7)轻推本身与健康无关。总体而言,轻推有效地影响了消费相关行为。相对于中性对照组,健康的食物和身体刺激会鼓励更健康的行为,而相对于中性对照组,不健康的食物刺激会鼓励不健康的行为。相对于比较/控制条件,非健康相关的轻推影响了预期方向的行为。轻推的有效性,特别是对于不健康食物的轻推,受到参与者年龄和体重、轻推时机(启动/提示)结果测量(摄入/选择)、健康(混合/健康/不健康)以及结果是真实的还是假设的影响。研究还确定了一系列参与者、助推和结果相关机制,这些机制是助推有效性的基础。研究结果支持视觉线索和启动物在诱导消费相关行为变化方面的有效性,表明如果使用正确的推动,它们可能有效地鼓励更健康的消费。结果还表明,不同形式的轻推可能在不同的情况下更合适(例如,对于不同类型的参与者或与食物相关的结果)。需要进一步的研究来彻底了解这些推动的机制及其有效性。
