Objective

The transformation framework conceptualizes social media as reshaping traditional peer influences and could enhance understanding of disordered eating. This cross-sectional study examined (1) independent associations of friend dieting and social media exposure with eating pathology, (2) whether social media exposure moderates the relationship between friend dieting and eating pathology, and (3) explored whether sex and age moderate independent and combined effects of friend dieting and social media exposure on eating pathology.

Method

A large sample of men and women (N = 1860) ranging in age from 28 to 69 years (M = 47.24 years, SD = 10.71), completed surveys assessing friends' behaviors, social media exposure, and eating pathology.

Results

Friend dieting and social media exposure showed independent associations with bulimic symptoms and drive for thinness. Greater social media exposure strengthened the relationship between friend dieting and bulimic symptoms in younger men and older women, and between friend dieting and drive for thinness in younger men and men at the mean age.

Discussion

Findings partially support hypotheses from the transformation framework, with the most consistent support found for younger men. Future work should examine how social media exposure amplifies the frequency, immediacy, and impact of peer influence on disordered eating to inform social media literacy programs tailored to adults.

目的：转型框架将社交媒体概念化为重塑传统同伴影响，并可以增强对饮食失调的理解。本横断面研究考察了(1)朋友节食和社交媒体暴露与饮食病理之间的独立关联，(2)社交媒体暴露是否调节朋友节食和饮食病理之间的关系，(3)探讨性别和年龄是否调节朋友节食和社交媒体暴露对饮食病理的独立和联合影响。方法：选取年龄在28岁至69岁之间（M = 47.24岁，SD = 10.71）的1860名男性和女性，完成对朋友行为、社交媒体曝光和饮食病理的调查。结果：朋友节食和社交媒体曝光与暴食症症状和瘦身动力有独立的联系。在年轻男性和老年女性中，更多的社交媒体曝光强化了朋友节食与暴食症症状之间的关系，在年轻男性和平均年龄男性中，朋友节食与追求瘦身之间的关系。讨论：研究结果部分支持来自转化框架的假设，最一致的支持是在年轻男性中发现的。未来的工作应该研究社交媒体曝光如何放大同伴影响对饮食失调的频率、即时性和影响，从而为针对成年人的社交媒体扫盲计划提供信息。

Experiencing loss of control (LOC) while eating is distressing to men and associated with many negative outcomes. Yet, investigations of LOC eating have focused on women. Some data suggest the factors that contribute to the onset and maintenance of these behaviors differ for men. The current study explored whether specific stressors, body dissatisfaction, dieting, hunger, food cravings, and food exposure were associated with same- and next-day LOC eating in young men. Participants included 41 men (18-35y; Mage = 25.4 ± 5.4) who reported engaging in 4 ≥ LOC eating episodes in the prior month. They completed a 14-day ecological momentary assessment protocol. The following predicted higher odds of same-day LOC eating: seeing/smelling appetizing foods; seeing other people eat/prepare appetizing foods; hearing other people talk about appetizing foods; ease of access to appetizing food; and problems with family members and money (odds ratios ≥1.43, ps ≤ 0.0382). The following predicted next-day LOC eating: craving one or more foods; seeing other people eat/prepare appetizing foods; hearing other people talk about appetizing foods; and problems with family members and physical pain (odds ratios ≥1.54, ps ≤ 0.0430). Problems with school/work, friends, and romantic relationships, dieting, hunger, and body dissatisfaction were not significantly associated with same- or next-day LOC eating. After applying a Benjamini-Hochberg correction, only seeing other people eat/prepare appetizing foods was associated with higher odds of same-day LOC eating (p corrected = 0.0136); all next-day associations were non-significant. Data suggest that exposure to appetizing foods in various forms may be the experience most closely related to young men's risk for LOC eating.

进食时失去控制（LOC）对男性来说是一种痛苦，并与许多负面结果有关。然而，对LOC饮食的调查主要集中在女性身上。一些数据表明，导致这些行为开始和维持的因素对男性来说是不同的。目前的研究探讨了特定的压力源、身体不满、节食、饥饿、食物渴望和食物暴露是否与年轻男性当天和第二天的LOC饮食有关。参与者包括41名男性（18-35岁；年龄= 25.4±5.4），报告在前一个月有4次≥LOC进食发作。他们完成了为期14天的生态瞬时评估方案。以下几点预测了当天进食的高概率：看到/闻到诱人的食物；看到别人吃/准备美味的食物；听别人谈论开胃的食物；容易获得开胃食品；家庭成员和金钱问题（比值比≥1.43,ps≤0.0382）。以下预测了第二天的LOC饮食：渴望一种或多种食物；看到别人吃/准备美味的食物；听别人谈论开胃的食物；家庭成员问题和身体疼痛（比值比≥1.54,ps≤0.0430）。学校/工作、朋友、恋爱关系、节食、饥饿和对身体不满意的问题与当天或第二天的LOC饮食没有显著关联。在应用Benjamini-Hochberg校正后，只看到其他人吃/准备开胃食物与更高的同日LOC进食几率相关（p校正= 0.0136）；所有第二天的关联都不显著。数据显示，接触各种形式的开胃食物可能是与年轻男性患LOC风险最密切相关的经历。

Introduction

Disordered eating (DE) is primarily observed in endurance athletes and sports that emphasize aesthetics. However, DE prevalence, exercise dependence (EXD), body dissatisfaction, and fueling habits in resistance-trained individuals—particularly CrossFit® athletes—are not well understood. CrossFit® promotes a culture that encourages strong, athletic, and muscular bodies. Both CrossFit® and endurance athletes often strive for low body fat percentages to enhance performance, which may contribute to body dissatisfaction, EXD, and eating concerns. This cross-sectional study investigated DE prevalence and its associations with EXD risk, body dissatisfaction, and fueling habits in female CrossFit®-only (CO) versus CrossFit® plus endurance (CE) athletes.

Methods

Participants (n = 325) completed a Qualtrics survey assessing DE, EXD, body dissatisfaction, and fueling practices.

Results

Across the sample, 37.2 % of participants were at risk for DE, and 84.6 % were classified as symptomatic for EXD. CO athletes were at a significantly greater risk (p < 0.001) for both DE and EXD compared with CE athletes. Athletes at risk for DE were significantly more likely to be symptomatic for EXD, train more days per week, report a stronger desire for muscularity, and follow specific dietary patterns to attain an ideal body.

Conclusion

Given the high prevalence of DE and EXD among female CrossFit® athletes, incorporating both screening tools is an important step in the initial evaluation process for Relative Energy Deficiency in Sport (REDs).

饮食失调（DE）主要在耐力运动员和强调审美的运动中观察到。然而，阻力训练个体（特别是CrossFit®运动员）的DE患病率、运动依赖（EXD）、身体不满和加油习惯尚未得到很好的了解。CrossFit®提倡一种鼓励强壮、运动和肌肉的文化。CrossFit®和耐力运动员经常努力争取低体脂百分比来提高成绩，这可能会导致身体不满，EXD和饮食问题。这项横断面研究调查了女性CrossFit®（CO）与CrossFit®加耐力（CE）运动员的DE患病率及其与EXD风险、身体不满和加油习惯的关系。方法参与者（n = 325）完成了一项质量调查，评估DE、EXD、身体不满和燃料练习。结果在整个样本中，37.2%的参与者有DE风险，84.6%的参与者被归类为EXD症状。与CE运动员相比，CO运动员发生DE和EXD的风险明显更高（p < 0.001）。有DE风险的运动员明显更有可能出现EXD症状，每周训练天数更多，对肌肉的渴望更强烈，并遵循特定的饮食模式来获得理想的身材。鉴于DE和EXD在女性CrossFit®运动员中的高患病率，结合这两种筛查工具是对运动中相对能量缺乏症（red）初步评估过程中的重要一步。

Introduction

Recent US-based datasets (Ns > 1000) show over 1-in-4 adults suffer from clinically significant eating disorder (ED) symptoms. Methods for preventing subthreshold problems from becoming full-threshold EDs are needed. An 8-week, single-arm feasibility study of a mobile heart rate variability biofeedback (HRVB) app supported strong acceptability and preliminary efficacy for reducing ED symptoms. The present study investigated potential mechanisms of change from pre- to post-intervention.

Method

Participants were 24 healthcare workers recruited during the COVID-19 pandemic who scored in the clinically significant range on the Loss of Control Eating Scale-Brief (LOCES-Brief) (92 % female, 83 % non-Hispanic white, Mean age = 42; SD = 11.8). Measures included the eight subscales from the Multidimensional Assessment of Interoceptive Awareness-2 (MAIA-2) for interoceptive sensibility, and the Eating Disorder Examination-Questionnaire 7-item Short (EDE-Q7) and LOCES-Brief for ED symptoms. Mediation analyses were conducted using the MEMORE macro for repeated measures, with indirect effects evaluated via 95 % Monte Carlo confidence intervals.

Results

Significant indirect effects on EDE-Q7 scores were found for MAIA-2 ‘noticing’, ‘attention-regulation’, ‘emotional-awareness’, ‘self-regulation’, and ‘body-listening’ subscales. ‘Not-worrying’, ‘not-distracting’, and ‘trusting’ did not significantly mediate EDE-Q7 changes. For LOCES-Brief, significant indirect effects were found for ‘trusting’. No other MAIA-2 subscales showed statistically significant indirect effects for LOCES-Brief.

Conclusion

Findings suggest HRV biofeedback may reduce ED symptoms by enhancing interoceptive skills. These results support further investigation into biofeedback as a low-cost, scalable intervention for populations at risk for EDs. Future studies should evaluate fully powered controlled efficacy trials of mobile HRVB as a preventive strategy for eating and body-related mental health concerns.

最近基于美国的数据集（Ns > 1000）显示，超过1 / 4的成年人患有临床显著的饮食失调（ED）症状。需要防止阈下问题变成全阈值问题的方法。一项为期8周的单臂可行性研究表明，移动心率变异性生物反馈（HRVB）应用程序具有很强的可接受性和减轻ED症状的初步疗效。本研究探讨了从干预前到干预后的潜在变化机制。参与者是在COVID-19大流行期间招募的24名卫生保健工作者，他们在饮食失控量表-简要（loes -简要）中得分在临床显著范围内（92%为女性，83%为非西班牙裔白人，平均年龄= 42;SD = 11.8）。测量方法包括内感意识多维评估-2 （MAIA-2）的8个子量表，以及ED症状的饮食失调检查问卷（ED - q7）和loes - brief。中介分析使用MEMORE宏进行重复测量，间接效应通过95%蒙特卡洛置信区间进行评估。结果MAIA-2“注意”、“注意调节”、“情绪意识”、“自我调节”和“身体倾听”分量表对ed - q7得分有显著的间接影响。“不担心”、“不分心”和“信任”并没有显著调节ed - q7的变化。对于LOCES-Brief，“信任”有显著的间接影响。没有其他MAIA-2量表显示loes - brief的间接影响有统计学意义。结论HRV生物反馈可能通过增强内感受能力来减轻ED症状。这些结果支持进一步研究生物反馈作为一种低成本、可扩展的干预措施，用于有ed风险的人群。未来的研究应该评估移动HRVB作为饮食和身体相关心理健康问题的预防策略的完全有效对照疗效试验。

Background

Body talk, both negative (i.e., fat talk and muscle talk) and positive, reflects how people discuss their bodies verbally and is closely linked to eating disorder (ED) pathology in younger populations. However, these variables have remained largely unexamined in older adults. Given their increasing vulnerability to ED, the study addressed the research gap by investigating body talk and ED pathology in the Chinese older adults. Based on implicit theories, the moderating role of growth mindset of self-regulation was explored to further inform interventions.

Methods

A sample of 408 Chinese older adults (45.3 % female; M_age = 62.43 years, SD = 3.39, Range = 60 to 79) voluntarily completed an anonymous survey through an online crowdsourcing platform.

Results

All types of body talk were significantly correlated with ED pathology in older adults in the hypothesized directions, whereas growth mindset of self-regulation only significantly moderated the relationship between negative body talk and ED pathology. Contrary to the expectations or our hypotheses, growth mindset strengthened the positive association between negative body talk and ED pathology.

Discussion

Our findings contribute new evidence regarding whether and how negative and positive types of body talk are associated with older adults' ED pathology. The unexpected direction of growth mindset effect offers insights that can serve as a valuable basis for further research with important implications for developing interventions to avoid unintended adverse effects on body image or eating behaviors in older adults.

背景：身体谈话，无论是消极的（即脂肪谈话和肌肉谈话）还是积极的，都反映了人们如何口头讨论他们的身体，并且与年轻人群的饮食失调（ED）病理密切相关。然而，这些变量在老年人中仍未得到检验。鉴于他们越来越容易患ED，本研究通过调查中国老年人的肢体语言和ED病理来弥补研究空白。以内隐理论为基础，探讨成长心态对自我调节的调节作用，为干预提供依据。方法：对408名中国老年人（女性45.3%，年龄62.43岁，SD = 3.39，范围60 ~ 79）通过网络众包平台自愿完成匿名调查。结果：在假设的方向上，所有类型的肢体语言与老年人ED病理均显著相关，而自我调节的成长心态仅显著调节负性肢体语言与ED病理的关系。与我们的预期或假设相反，成长心态加强了消极身体谈话与ED病理之间的正相关。讨论：我们的发现提供了新的证据，关于消极和积极类型的身体谈话是否以及如何与老年人的ED病理相关。成长心态效应的意外方向为进一步研究提供了有价值的基础，对开发干预措施以避免对老年人身体形象或饮食行为的意外不利影响具有重要意义。

The association between sociocultural pressure and muscle dysmorphia (MD) is well-documented, yet the psychological variables involved require further investigation. This cross-sectional study examined a statistical model in 95 male exercisers in Spain (M age = 34.40) to explore the roles of appearance motivation and cognitive flexibility. Specifically, it tested the indirect association between the perceived influence of appearance ideals and MD symptoms through appearance motivation, and whether cognitive flexibility moderated this relationship. The overall model accounted for 48 % of the variance in MD symptoms (R² = 0.48), controlling for age. Results indicated a significant indirect association through appearance motivation (b = 0.16, 95 % CI [0.03, 0.36]). Additionally, a significant moderation was found (p = .043); the positive association between the influence of appearance ideals and MD symptoms was weaker for individuals with higher levels of cognitive flexibility. These findings are consistent with a model where MD symptom endorsement is linked to appearance motivation, while higher cognitive flexibility is related to a less pronounced association between sociocultural pressures and MD symptoms. Cognitive flexibility is highlighted as a potential protective correlate, suggesting that interventions could target motivational patterns and cognitive skills.

社会文化压力与肌肉畸形（MD）之间的关系已被充分证明，但涉及的心理变量需要进一步调查。本研究采用统计学模型对95名西班牙男性锻练者（M年龄= 34.40岁）进行分析，探讨外观动机与认知灵活性的关系。具体来说，它测试了通过外表动机感知到的外貌理想影响与MD症状之间的间接关联，以及认知灵活性是否调节了这种关系。在控制年龄的情况下，总体模型占MD症状方差的48% （R2 = 0.48）。结果表明，通过外观动机存在显著的间接关联（b = 0.16, 95% CI[0.03, 0.36]）。此外，发现显著的缓和（p = .043）；对于认知灵活性水平较高的个体，理想外表与MD症状之间的正相关影响较弱。这些发现与MD症状认可与外观动机相关的模型一致，而较高的认知灵活性与社会文化压力与MD症状之间不太明显的关联相关。认知灵活性被强调为潜在的保护性关联，表明干预可以针对动机模式和认知技能。

Restrained eaters are individuals who chronically attempt to restrict caloric intake for weight loss or maintenance. However, only a minority of this population sustains long-term dietary control. Based on the conceptual separation between motivational wanting (cue-driven desire) and hedonic liking (consumption pleasure) proposed by the incentive-sensitization theory, this study investigated differences in food reward processing between low-disinhibited restrained eaters (LD-REs, n = 29) and high-disinhibited restrained eaters (HD-REs, n = 30). By assessing changes in wanting and liking ratings for high-calorie snacks under hunger and satiety states, we identified significantly distinct reward processing patterns between groups. Specifically, HD-REs exhibited higher wanting ratings than LD-REs across both physiological states, despite comparable liking ratings between groups. Crucially, during the transition from hunger to satiety, LD-REs demonstrated a significantly greater reduction in wanting than HD-REs, while liking changes showed no significant group difference. These results suggest that dysregulation in restrained eating is primarily associated with an imbalance in the motivational component of food reward, rather than the hedonic component. This study provides preliminary behavioral evidence highlighting distinct food reward patterns between LD-REs and HD-REs subgroups, contributing to a more nuanced theoretical framework for understanding individual differences in eating behavior regulation.

节制饮食者是那些长期试图限制热量摄入以减轻或维持体重的人。然而，只有少数人能够长期控制饮食。基于激励-敏感化理论提出的动机欲望（线索驱动欲望）和享乐喜好（消费愉悦）的概念分离，本研究探讨了低去抑制克制进食者（LD-REs, n = 29）和高去抑制克制进食者（HD-REs, n = 30）食物奖励加工的差异。通过评估在饥饿和饱腹状态下对高热量零食的想要和喜欢等级的变化，我们发现了组间显著不同的奖励处理模式。具体来说，在两种生理状态下，HD-REs表现出比LD-REs更高的想要评级，尽管两组之间的喜欢评级相当。至关重要的是，在从饥饿到饱腹的转变过程中，LD-REs比HD-REs表现出更大的欲望减少，而喜欢的变化没有显着的组差异。这些结果表明，节制饮食的失调主要与食物奖励动机成分的不平衡有关，而不是与享乐成分有关。这项研究提供了初步的行为证据，突出了LD-REs和HD-REs亚组之间不同的食物奖励模式，为理解饮食行为调节的个体差异提供了更细致的理论框架。

Background

Social media use has been implicated in the development and maintenance of eating disorder (ED) symptoms, yet most existing research has focused on general social media engagement rather than addictive patterns of use. This study expands that work by examining Instagram—a widely used social media platform—and the role of Instagram addiction, defined as a compulsive and dysregulated pattern of engagement, in ED symptoms. Additionally, prior research has largely assumed that social media use precedes ED symptoms, despite the theoretical plausibility of a bidirectional relationship. This study aimed to examine prospective, bidirectional associations between Instagram addiction and core ED symptoms.

Method

A prospective study was conducted with 1710 adult women (M = 33.76 years; SD = 9.25, range = 18–80) recruited from an online self-help platform for EDs. Participants completed self-report measures of Instagram addiction, binge eating severity, inflexible dieting, and overvaluation of weight and shape. Cross-lagged panel models were estimated to assess bidirectional associations at Time 1 (T1; baseline) and Time 2 (T2; 3-month follow-up).

Results

Significant, positive, and bidirectional relationships were observed between Instagram addiction and both binge eating and inflexible dieting. In contrast, only a unidirectional association was found between T1 overvaluation and T2 Instagram addiction.

Conclusions

These findings provide novel evidence of potential feedback loops between specific ED symptoms and Instagram addiction. Results highlight the importance of integrating strategies to address problematic Instagram use within ED prevention and treatment efforts.

社交媒体的使用与饮食失调（ED）症状的发展和维持有关，但大多数现有研究都集中在一般的社交媒体参与上，而不是上瘾的使用模式。这项研究通过检查Instagram（一个广泛使用的社交媒体平台）和Instagram成瘾（被定义为一种强迫性和失调的参与模式）在ED症状中的作用来扩展这项工作。此外，先前的研究在很大程度上假设社交媒体的使用先于ED症状，尽管理论上存在双向关系。本研究旨在研究Instagram成瘾与核心ED症状之间的前瞻性、双向关联。方法采用前瞻性研究，从急诊在线自助平台招募1710名成年女性（M = 33.76岁，SD = 9.25，范围= 18-80）。参与者完成了对Instagram成瘾、暴饮暴食严重程度、不灵活的节食以及对体重和体型的高估的自我报告。估计交叉滞后面板模型评估时间1 （T1；基线）和时间2 （T2； 3个月随访）的双向关联。结果Instagram成瘾与暴饮暴食和不灵活的节食之间存在显著的、积极的、双向的关系。相比之下，T1高估与T2 Instagram成瘾之间仅存在单向关联。这些发现为特定ED症状和Instagram成瘾之间潜在的反馈循环提供了新的证据。结果强调了在ED预防和治疗工作中整合策略来解决Instagram使用问题的重要性。

Objective

Disordered eating is a public health concern linked with many adverse outcomes. Research has identified disparities in disordered eating prevalence across multiple social positions, but less work has examined sexual orientation as a primary consideration alongside other marginalized positions. This study examines prevalence of disordered eating behaviors across sexual orientation in combination with race/ethnicity and gender among young adults.

Methods

Participants included 960 young adults involved in Project EAT 2023. The adjusted probabilities of disordered eating outcomes (dieting, unhealthy weight-control behaviors [UWCB], and binge eating) among participants who identified as straight or a marginalized sexual orientation by gender and race/ethnicity were calculated from logistic regression models.

Results

Asian young adults with a marginalized sexual orientation had lower prevalence of dieting and UWCB compared to their straight peers. In contrast, Hispanic participants with a marginalized sexual orientation had greater prevalence of UWCB than straight Hispanic participants. White participants with a marginalized sexual orientation had a higher prevalence of binge eating compared to their straight peers. Straight men additionally reported greater dieting than men with a marginalized sexual orientation.

Discussion

This study contributes to a growing body of work on the intersectional nature of propensity for disordered eating behaviors. The findings highlight a need for more nuanced approaches to research, prevention, and intervention.

目的饮食失调是一个与许多不良后果相关的公共卫生问题。研究发现，在不同的社会地位中，饮食失调的患病率存在差异，但很少有研究将性取向与其他边缘化地位一起作为主要考虑因素。这项研究调查了年轻人中跨性取向、种族/民族和性别的饮食失调行为的患病率。研究对象包括960名参与EAT 2023项目的年轻人。根据性别和种族/民族确定为异性恋或边缘性取向的参与者，通过逻辑回归模型计算饮食失调结局（节食、不健康体重控制行为和暴饮暴食）的调整概率。结果与异性恋同龄人相比，边缘性取向的亚裔年轻人节食和超长体重的患病率较低。相反，边缘性取向的西班牙裔参与者比异性恋的西班牙裔参与者有更高的UWCB患病率。与异性恋同龄人相比，性取向被边缘化的白人参与者暴食的患病率更高。据报道，异性恋男性比边缘性取向男性节食更多。这项研究为越来越多的关于饮食失调倾向的交叉性质的工作做出了贡献。研究结果强调需要更细致入微的研究、预防和干预方法。

Disordered eating (DE) is becoming increasingly prevalent, and fitness professionals may be at elevated risk due to profession-specific pressures such as increased physique-focus and emphasis on exercise. This review aimed to synthesise existing evidence surrounding the prevalence of DE amongst fitness professionals. This review followed the Preferred Reporting Item for Systematic Reviews and Meta-analyses (PRISMA) process. The databases Ovid (EMBASE, MEDLine, PsycINFO), CINAHL, Prospero, Scopus, Web of Science and ProQuest were searched for studies published between 2004 and 2024. Studies were included if they assessed for DE in fitness professionals using a DE assessment instrument with specific cut-off scores. A total of nine studies, represented in 14 articles were included in the review. High levels of DE were evident amongst fitness professionals (personal trainers, group fitness instructors). Personal trainers exhibited higher rates compared to other fitness professionals, whilst high-performance coaches showed the lowest. Methodological inconsistencies, such as variation in assessment tools and small sample sizes reduce the generalisability of findings. However, findings suggest that DE is a concern amongst fitness professionals and should be addressed by appropriate education and screening programmes.

饮食失调（DE）正变得越来越普遍，而健身专业人士可能由于职业特定的压力而面临更高的风险，例如对身体的关注和对运动的重视。本综述旨在综合健身专业人员中DE患病率的现有证据。本综述遵循系统评价和荟萃分析首选报告项目（PRISMA）流程。在Ovid (EMBASE, MEDLine, PsycINFO)， CINAHL, Prospero, Scopus， Web of Science和ProQuest数据库中检索了2004年至2024年间发表的研究。如果研究使用具有特定分值的DE评估工具评估健身专业人员的DE，则纳入研究。本综述共纳入了14篇文章中的9项研究。在健身专业人士（私人教练、团体健身教练）中，DE水平明显较高。与其他健身专业人士相比，私人教练的自杀率更高，而高性能教练的自杀率最低。方法上的不一致，例如评估工具的差异和小样本量降低了研究结果的普遍性。然而，研究结果表明，DE是健身专业人士关注的问题，应该通过适当的教育和筛查计划来解决。
