Objective

Adolescence is a key period for the development of eating behaviours. To date, little attention has been paid to the development of positive eating behaviours during adolescence, and longitudinal research with such a holistic focus is lacking. To provide a better understanding of adolescent eating behaviours, this study examined patterns of stability and change in eating profiles among community youth. In addition, this study examined how these profiles and patterns were related to background, psychological, and contextual variables.

Method and Results

This longitudinal study with two timepoints included 608 adolescents and emerging adults at the first timepoint for the current analyses (T1: 64.3% female; M_age = 16.99; SD = 1.24; range = 14–21 years). Using latent transition analysis (LTA), three eating behaviour profiles emerged: a competent eating profile, a subclinical profile, and a clinical profile. Although most individuals in the competent eating and clinical profiles remained within their profile over time, individuals in the subclinical profile were more likely to progress toward greater eating competence or more severe eating disorder symptoms. Using multinomial logistic regression models; sex, adjusted BMI, identity, embodiment, and critical parent and peer eating messages appeared to be related to profile membership, whereas only age, sex, and adjusted BMI were related to transition patterns.

Conclusion

The present study informs theory and practice by identifying subgroups of adolescents who differ in their eating behaviours. In addition, these findings provide insight into which aspects are meaningfully related to stability and variability in eating behaviours, supporting the development of targeted interventions.

目的：青春期是饮食行为发展的关键时期。迄今为止，很少有人关注青春期积极饮食行为的发展，缺乏这样一个整体的纵向研究。为了更好地了解青少年的饮食行为，本研究考察了社区青少年饮食状况的稳定性和变化模式。此外，本研究还考察了这些概况和模式与背景、心理和上下文变量的关系。方法和结果：这项纵向研究有两个时间点，在当前分析的第一个时间点包括608名青少年和初成人(T1: 64.3%女性；法师= 16.99；sd = 1.24；范围= 14-21岁)。使用潜在转变分析（LTA），出现了三种饮食行为概况：胜任饮食概况，亚临床概况和临床概况。虽然大多数具有进食能力和临床特征的个体随着时间的推移保持在他们的特征范围内，但亚临床特征的个体更有可能向更强的进食能力或更严重的进食障碍症状发展。采用多项逻辑回归模型；性别、调整后的体重指数、身份、体现、父母和同伴的关键饮食信息似乎与概况成员有关，而只有年龄、性别和调整后的体重指数与过渡模式有关。结论：本研究通过确定不同饮食行为的青少年亚群，为理论和实践提供了信息。此外，这些发现提供了洞察哪些方面与饮食行为的稳定性和可变性有意义的关系，支持有针对性的干预措施的发展。

Objective

Altered reward processing is proposed to be central to the pathology of anorexia nervosa (AN). This study aimed to investigate how aspects of reward dysfunction relate to suicidal thoughts and behaviours (STBs) in AN.

Method

We compared responses on self-report measures of general (i.e., anticipatory, consummatory, and social reward) and disorder-specific (i.e., self-starvation reward) reward between individuals with AN with (AN + STBs; n = 28) or without (AN; n = 31) lifetime active STBs and healthy controls (HC; n = 32). Further, we examined whether interactions between general and disorder-specific reward dysfunction were associated with lifetime active STBs in AN.

Results

Compared to AN and HC groups, the AN + STBs group reported significantly lower anticipatory and social reward; both AN + STBs and AN groups reported higher self-starvation reward than HCs. When accounting for the effects of depression, group differences became non-significant for general rewards but remained significant for disorder-specific reward processing. The interaction between anticipatory and self-starvation reward was significantly associated with STB risk beyond the effects of depression: AN participants reporting high self-starvation reward were at elevated STB risk regardless of anticipatory reward levels, whereas those with low self-starvation reward showed increased STBs only when anticipatory reward was also low.

Conclusion

Our results suggest that the combination of general and disorder-specific reward processes may shape distinct suicidality risk profiles in AN.

目的：改变的奖励加工被认为是神经性厌食症（AN）病理的核心。本研究旨在探讨AN中奖励功能障碍与自杀念头和行为（STBs）的关系。方法：我们比较了AN + STBs患者自我报告的一般奖励（即预期奖励、圆满奖励和社会奖励）和障碍特异性奖励（即自我饥饿奖励）的反应；n = 28)或无(AN；n = 31)终生活动性性病患者和健康对照(HC；n = 32)。此外，我们研究了AN中一般和疾病特异性奖励功能障碍之间的相互作用是否与终生活动性STBs相关。结果：与AN和HC组相比，AN + STBs组的预期奖励和社会奖励显著降低；AN + stb组和AN组报告的自我饥饿奖励高于hc组。当考虑到抑郁的影响时，对于一般奖励，组间差异变得不显著，但对于特定障碍的奖励处理，组间差异仍然显著。预期奖励和自我饥饿奖励之间的相互作用与STB风险显著相关，而不仅仅是抑郁的影响：无论预期奖励水平如何，报告高自我饥饿奖励的AN参与者都有较高的STB风险，而那些自我饥饿奖励低的参与者只有在预期奖励也低的情况下才显示出增加的STB风险。结论：我们的研究结果表明，一般奖励过程和障碍特异性奖励过程的结合可能会形成AN中不同的自杀风险概况。

European Eating Disorders Review

Pub Date : 2025-06-11 DOI: 10.1002/erv.70003

Danielle Lambert, Emma Willmott, Jo Cryer

Background

Avoidant restrictive food intake disorder (ARFID) was introduced as a diagnosis to our mental health diagnostic manuals in 2013. Referrals to a UK-based tertiary feeding and eating disorder service for feeding difficulties, including ARFID, increased by 37% since 2019.

Objective

This commentary discusses potential reasons for the increase observed in referrals for feeding difficulties, including ARFID presentations.

Main Discussion

We discuss several factors which may be contributing to the rise in referrals; a growing recognition of ARFID since its diagnostic introduction 10 years ago, the broad and inclusive diagnostic criteria for ARFID, the heterogeneous presentation of ARFID and its high co-occurrence of neurodevelopmental and mental health conditions, and a lack of established evidence-based interventions at present. We also consider broader contextual factors, including the possible impact of the COVID-19 pandemic, sociocultural changes in mealtime practices and food availability and increasing systemic pressures on services.

Conclusions and Implications

Understanding the multi factorial causes behind increased referrals is crucial for developing effective services that can manage the demands, are responsive to the needs of patients and provide appropriate and timely care for children and their families.

背景：回避性限制性食物摄入障碍（ARFID）于2013年被引入我们的心理健康诊断手册。自2019年以来，向英国三级喂养和饮食失调服务机构（包括ARFID）转诊的喂养困难人数增加了37%。目的：这篇评论讨论了在喂养困难的转诊中观察到的增加的潜在原因，包括ARFID的介绍。主要讨论：我们讨论了可能导致转诊增加的几个因素；ARFID自10年前引入诊断以来，越来越多的人认识到ARFID， ARFID的诊断标准广泛而包容，ARFID的异质表现及其神经发育和精神健康状况的高度共发，以及目前缺乏已建立的循证干预措施。我们还考虑了更广泛的背景因素，包括2019冠状病毒病大流行可能产生的影响、用餐习惯和食物供应方面的社会文化变化，以及服务业面临的系统性压力日益增加。结论和意义：了解转诊增加背后的多因素原因对于开发有效的服务至关重要，这些服务可以管理需求，响应患者的需求，并为儿童及其家庭提供适当和及时的护理。

Objective

Social media use can negatively impact both physical and mental well-being by influencing aspects like body image and potentially leading to eating disorders. This issue is particularly significant during pregnancy, a time when maternal and foetal health are heavily influenced by nutrition. This study aims to examine how social media use affects the relationship between body image and disordered eating attitudes in the third trimester of pregnant women.

Method

A cross-sectional survey was conducted with a convenience sample of 368 pregnant women during their routine prenatal visits. Data collection occurred between May 2023 to May 2024, utilising the Social Media Use Integration Scale, the Disordered Eating Attitudes in Pregnancy Scale and the Body Image in Pregnancy Scale. The study's hypotheses were analysed using structural equation modelling.

Results

The study demonstrated significant positive correlations among body image perception, disordered eating attitudes, and social media use during the third trimester of pregnancy. Particularly, higher levels of social media use exacerbated the negative effects of body image perception on disordered eating attitudes. The overall model explained 29.21% of the variance in disordered eating attitudes, with social media use playing a significant moderating role.

Conclusion

These findings suggest that negative body image perceptions and social media use affect disordered eating attitudes in the third trimester of pregnant women. Furthermore, social media use serves as a significant moderator, increasing the negative effects of body image concerns. Healthcare providers should take into account the influence of social media on pregnant women’s body image and eating behaviours when developing intervention strategies. Implementing educational programs that promote a positive body image perception and enhance media literacy could be beneficial.

目的：社交媒体的使用会影响身体形象等方面，并可能导致饮食失调，从而对身心健康产生负面影响。这一问题在怀孕期间尤为重要，因为在这一时期，营养严重影响孕产妇和胎儿的健康。本研究旨在研究社交媒体的使用如何影响孕妇在妊娠晚期的身体形象和饮食失调态度之间的关系。方法：采用横断面调查法对368例孕妇进行常规产前检查。数据收集时间为2023年5月至2024年5月，使用社交媒体使用整合量表、孕期饮食失调态度量表和孕期身体形象量表。采用结构方程模型对研究假设进行了分析。结果：研究表明，在妊娠晚期，身体形象感知、饮食态度紊乱和社交媒体使用之间存在显著的正相关。特别是，较高水平的社交媒体使用加剧了身体形象感知对饮食失调态度的负面影响。整体模型解释了29.21%的饮食失调态度差异，社交媒体的使用起到了显著的调节作用。结论：这些研究结果表明，负面的身体形象认知和社交媒体的使用影响了妊娠晚期妇女的饮食失调态度。此外，社交媒体的使用起到了重要的调节作用，增加了对身体形象担忧的负面影响。医疗保健提供者在制定干预策略时应考虑到社交媒体对孕妇身体形象和饮食行为的影响。实施教育计划，促进积极的身体形象感知和提高媒体素养可能是有益的。

Background and objective

Anorexia nervosa (AN) is a mental disorder most prevalent among adolescent females, with rising cases in younger and more culturally diverse populations. Unhealthy activity patterns are common and have been linked to increased relapse rates; however, data on objectively measured physical activity levels (PALs) in this population is scarce. This study aimed to examine PALs and sedentary time (ST) in patients with AN.

Methods

Following PRISMA guidelines, 16 studies met inclusion criteria (PICO strategy). Sensitivity and subgroup analyses by age and treatment phase were performed.

Results

Patients' mean age ranged from 12.6 to 36.2 years. Pooled mean ST was high (617.49 min/day). Light physical activity (LPA), moderate physical activity (MPA) and moderate-to-vigorous physical activity (MVPA) were higher in adult studies, while vigorous physical activity (VPA) was higher in adolescents. Steps were reported only in adult samples.

Conclusion

This is the first systematic review and meta-analysis assessing objectively measured PALs in AN patients. Findings reveal different PALs patterns by age-group, and insufficient data by treatment stage. These results identified a critical research gap essential for future development of targeted interventions and informed strategies to support recovery.

背景与目的：神经性厌食症（Anorexia neurovosa， AN）是一种常见于青春期女性的精神障碍，在年轻和文化多样化的人群中发病率呈上升趋势。不健康的活动模式很常见，与复发率增加有关；然而，这一人群中客观测量的身体活动水平（PALs）的数据很少。本研究旨在研究AN患者的PALs和久坐时间（ST）。方法：遵循PRISMA指南，16项研究符合纳入标准（PICO策略）。按年龄和治疗阶段进行敏感性和亚组分析。结果：患者平均年龄12.6 ~ 36.2岁。合并平均ST较高（617.49 min/day）。轻度体力活动（LPA）、中度体力活动（MPA）和中度至剧烈体力活动（MVPA）在成人研究中较高，而剧烈体力活动（VPA）在青少年研究中较高。仅在成人样本中报告了步骤。结论：这是第一个客观评估AN患者PALs的系统综述和荟萃分析。研究结果显示，不同年龄组的PALs模式不同，不同治疗阶段的数据不足。这些结果确定了一个关键的研究缺口，这对未来制定有针对性的干预措施和支持复苏的知情战略至关重要。

Background

Despite the severe and increasing burden of eating disorders (EDs) on children and adolescents, treatment services are typically only accessible after substantial waiting times. One strategy used to support families during the waitlist period is psychoeducation.

Objective

This pilot study aimed to evaluate the effectiveness of a 6-week pre-treatment psychoeducation and specialist medical management and group-based support programme for parents, targeting parental self-efficacy and preparedness for their child's upcoming treatment at an Australian specialist outpatient ED clinic.

Method

Waitlisted young people (197, mean age 14.55, SD = 1.70, 67% Anorexia Nervosa) and their parents (304) completed questionnaires assessing parents’ depression, anxiety and self-efficacy, and young people's depression, ED symptomology and BMI; these measures were completed pre- and post-programme and changes were assessed using multilevel models.

Results

Parents increased in self-efficacy, showed modest improvements in depression, and no significant change in anxiety. Young people showed significant improvements in global ED symptomology, BMI and depression.

Conclusions

Our findings suggest that a pre-treatment programme yields significant improvements in parental self-efficacy, which is key to effective treatment of EDs in young people. Additionally, modest but meaningful improvements to young people's weight and psychopathology are achievable before families commence an evidence-based outpatient treatment.

背景：尽管饮食失调（EDs）对儿童和青少年造成了严重且日益加重的负担，但通常只有在长时间等待后才能获得治疗服务。在等待名单期间支持家庭的一种策略是心理教育。目的：本试点研究旨在评估为期6周的治疗前心理教育、专科医疗管理和基于团体的父母支持计划的有效性，目标是父母的自我效能感和为孩子即将在澳大利亚专科门诊ED诊所接受治疗做好准备。方法：入选青少年（197例，平均年龄14.55岁，SD = 1.70，神经性厌食症67%）及其父母（304例）填写父母抑郁、焦虑、自我效能、青少年抑郁、ED症状、BMI问卷；这些措施在计划前后完成，并使用多层模型评估变化。结果：父母的自我效能感有所提高，抑郁有所改善，焦虑无明显变化。年轻人在ED症状、BMI和抑郁方面均有显著改善。结论：我们的研究结果表明，治疗前计划可以显著提高父母的自我效能感，这是有效治疗青少年ed的关键。此外，在家庭开始以证据为基础的门诊治疗之前，对年轻人的体重和精神病理的适度但有意义的改善是可以实现的。

Background-Objectives

Obesity is an increasing global public health problem with severe correlated chronic diseases (physical and mental disorders). The aim of this study is to identify nutrient patterns among young adults who are overweight or obese based on their dietary intake, and to explore the associations between nutrient patterns and sociodemographic and clinical variables (anthropometric, cardiometabolic, and psychological).

Methods

A voluntary response (non-random) sample involving N = 188 overweight and obese university students (men and women, with a mean age of 20.8 years [SD = 2.6]) was recruited. Pregnancy, endocrine-genetic disorders, weight-loss diet and use of treatments that could affect endocrine parameters were defined as exclusion criteria.

Results

Three nutritional patterns were identified, that explained 69% of the total variance: (a) NP1, characterised by a high intake of minerals and vitamins; (b) NP2, characterised by a high intake of carbohydrates; and (c) NP3, characterised by a high intake of fats and sodium. Higher mean scores in NP1 were related to female gender (p = 0.015), while higher NP1 and NP2 levels were associated to divorced/separated marital status (p = 0.007 and p = 0.041, respectively). Path analysis revealed a direct relationship between being within metabolically unhealthy obesity (MUO) levels and higher levels of anxiety (standardised coefficient St.Coeff = 0.14, p = 0.049), depression (St.Coeff = 0.17, p = 0.014) and stress (St.Coeff = 0.13, p = 0.048). In addition, the metabolic risk profile (the classification into MUO vs. MHO) achieved a mediational link between the factor scores for NP1 and a worse psychological state.

Discussion

This study provides empirical knowledge to design more effective prevention and treatment plans for young adults who are overweight or obese, considering the impact nutritional patterns have on metabolic and psychopathological distress.

背景目的：肥胖是一个日益严重的全球公共卫生问题，伴有严重的相关慢性疾病（身体和精神障碍）。本研究的目的是根据饮食摄入确定超重或肥胖的年轻人的营养模式，并探讨营养模式与社会人口学和临床变量（人体测量学、心脏代谢学和心理学）之间的关系。方法：采用自愿响应（非随机）抽样，共纳入N = 188名超重和肥胖大学生（男女均有，平均年龄20.8岁[SD = 2.6]）。怀孕、内分泌遗传疾病、减肥饮食和使用可能影响内分泌参数的治疗被定义为排除标准。结果：确定了三种营养模式，解释了总方差的69%:(a) NP1，其特征是大量摄入矿物质和维生素；(b) NP2，特点是大量摄入碳水化合物；(c) NP3，其特点是高脂肪和高钠摄入量。较高的NP1平均得分与女性有关（p = 0.015），而较高的NP1和NP2水平与离婚或分居的婚姻状况有关（p = 0.007和p = 0.041）。通径分析显示，代谢不健康肥胖（MUO）水平与较高水平的焦虑（标准化系数St.Coeff = 0.14, p = 0.049）、抑郁（St.Coeff = 0.17, p = 0.014）和压力（St.Coeff = 0.13, p = 0.048）之间存在直接关系。此外，代谢风险谱（分为MUO和MHO）在NP1因子得分和更差的心理状态之间实现了中介联系。讨论：本研究为考虑营养模式对代谢和精神病理困扰的影响，为超重或肥胖的年轻人设计更有效的预防和治疗方案提供了经验知识。

Objective

This study aims to explore the role of implicit visual processing in reinforcing maladaptive eating behaviours in Anorexia Nervosa-restricting subtype (AN-R), focussing on how high- and low-calorie food stimuli are processed at different stages.

Method

Thirty-two AN-R females and 36 healthy controls participated. Using a combination of novel paradigms in the field, the study employed: Breaking Continuous Flash Suppression (bCFS) for unconscious detection, Binocular Rivalry (BR) for perceptual dominance, and the Food Preference Approach-Avoidance Task (FP-AAT) for subconscious food associations.

Results

AN-R individuals exhibited prolonged perceptual dominance for high-calorie foods but simultaneously displayed stronger implicit avoidance tendencies towards these foods. Notably, the perceptual advantage correlated with heightened interoceptive awareness, while avoidance was linked to body dissatisfaction and difficulty tolerating bodily sensations. Conversely, healthy females showed the opposite pattern, implicitly approaching high-calorie foods while avoiding low-calorie foods, suggesting a more adaptive integration of food-related cues.

Conclusions

This study provides novel insights into the complex role of high-calorie foods in AN, highlighting whether and how different aspects of implicit visual processing influence eating behaviours, and underscoring the need for targeted interventions incorporating implicit cognitive mechanisms to address visual processing biases and support AN recovery.

目的：本研究旨在探讨内隐视觉加工在厌食症神经性限制亚型（AN-R）进食不良行为强化中的作用，重点研究高热量和低热量食物刺激在不同阶段的加工过程。方法：32名AN-R女性和36名健康对照。本研究采用打破连续闪光抑制（bCFS）作为无意识检测，双眼竞争（BR）作为感知优势，食物偏好趋近-回避任务（FP-AAT）作为潜意识食物联想。结果：AN-R个体对高热量食物表现出长期的感知优势，但同时对这些食物表现出更强的内隐回避倾向。值得注意的是，感知优势与增强的内感受意识相关，而回避与身体不满和难以忍受身体感觉有关。相反，健康的女性表现出相反的模式，隐性地接近高热量食物，同时避免低热量食物，这表明与食物相关的线索更具适应性整合。结论：本研究为高热量食物在AN中的复杂作用提供了新的见解，强调了内隐视觉加工的不同方面是否以及如何影响饮食行为，并强调了纳入内隐认知机制的有针对性干预措施的必要性，以解决视觉加工偏见并支持AN恢复。

Background

Chocolate is the most craved energy-dense food. Yet, most individuals can limit their chocolate consumption. Here, we investigate the cognitive mechanisms underlying chocolate consumption in a chocolate bogus taste test in a cross-sectional experimental design.

Method

High chocolate cravers abstained from chocolate for a week, followed by a virtual reality chocolate exposure with biometric trajectory recordings of their stopping responses and an ad-libitum bogus taste test of spontaneous chocolate intake. A single-target implicit association task and a computerised stop-signal task served as unstandardised control tasks 1–2 days before chocolate intake.

Results

Associations of parameters from all tasks with chocolate intake were small (|r| < 0.23). Elastic net models misestimated food intake by min. 160 kcal (generalisation: 180 kcal) and feature selection was only possible with L1 penalty. At the group level, participants showed a more controlled and delayed movement towards chocolate relative to neutral cues, evidenced by lower peak acceleration and peak velocity and faster stopping latency.

Discussion

The findings demonstrate the complex cognitive-behavioural underpinnings of food intake, food craving and abstinence.

背景：巧克力是人们最渴望的高能量食物。然而，大多数人都可以限制巧克力的摄入量。在这里，我们在横断面实验设计中研究巧克力虚假味道测试中巧克力消费的认知机制。方法：高巧克力渴望者在一周内不吃巧克力，然后进行虚拟现实巧克力暴露，记录他们停止反应的生物特征轨迹，并对自发摄入巧克力进行随意的虚假味觉测试。在巧克力摄入前1-2天，单目标内隐联想任务和计算机控制的停止信号任务作为非标准化控制任务。结果：所有任务的参数与巧克力摄入量的关联很小（b|或b|）讨论：研究结果证明了食物摄入、食物渴望和禁食的复杂认知行为基础。

Effects of Obesity on the Relationship Between Eating Behaviours and Cognitive Emotion Regulation in Chinese College Students: A Network Analysis 肥胖对中国大学生饮食行为与认知情绪调节关系的影响：一个网络分析

IF 3.4 2区心理学 Q1 PSYCHIATRY

European Eating Disorders Review

Background

Maladaptive eating behaviours and cognitive emotion regulation strategies are prevalent in obese populations, both of which have complex aetiologies and interact with each other. This study aimed to examine the interaction between eating behaviours and cognitive emotion regulation strategies, conceptualising symptoms as variables that can directly interact with each other, and explore differences between obese and non-obese populations.

Methods

742 obese and 810 non-obese students were recruited from a university in northern China. Network analysis was used to characterise the network of eating behaviours and cognitive emotion regulation strategies of obese and non-obese students and then compared two network structures' differences.

Results

The network structures of obese and non-obese students differed in terms of the global strength of connections between network symptoms. In the network structure of obese students, the highest key bridge symptom was “catastrophizing”, and the association between “catastrophizing” and “hunger” was the primary bridging edge, which were different from the network structure of non-obese students.

Conclusions

Our results suggest that in the obese population, more attention should be paid to certain maladaptive cognitive emotion regulation strategies such as catastrophizing, which provides new perspectives for preventing or intervening in abnormal eating behaviours (e.g., binge eating) or eating disorders in the obese population.

背景：饮食不良行为和认知情绪调节策略在肥胖人群中普遍存在，两者的病因复杂且相互作用。本研究旨在研究饮食行为和认知情绪调节策略之间的相互作用，将症状概念化为可以直接相互作用的变量，并探索肥胖和非肥胖人群之间的差异。方法：选取北方某高校肥胖学生742人，非肥胖学生810人。采用网络分析对肥胖和非肥胖学生的饮食行为和认知情绪调节策略网络进行表征，并比较两种网络结构的差异。结果：肥胖与非肥胖学生的网络结构在网络症状的整体连接强度上存在差异。在肥胖学生的网络结构中，“灾变”是最高的关键桥梁症状，“灾变”与“饥饿”之间的关联是主要的桥边，这与非肥胖学生的网络结构不同。结论：我们的研究结果提示，在肥胖人群中，应更多地关注某些适应不良的认知情绪调节策略，如灾难化，这为预防或干预肥胖人群的异常饮食行为（如暴食）或饮食失调提供了新的视角。
