Objective

There is limited information regarding emergency medical reviews (EMRs) and medical admission transfers for psychiatric eating disorders inpatients. We aimed to describe (i) EMRs during psychiatric inpatient eating disorders treatment at the Eating Disorders Unit (EDU), Austin Hospital in Melbourne, Victoria, and (ii) medical admission transfers during EDU admissions.

Methods

Retrospective review of patient files was undertaken for inpatients aged 18–65 years with an eating disorder who resided within the Body Image & Eating Disorders Treatment & Recovery Service (BETRS) catchment area and were admitted to EDU between 01/01/21 to 30/10/23.

Results

Among 177 EDU admissions there were 33 EMRs and 17 medical transfers. On average, inpatients with EMRs or medical transfers were older with greater medical multimorbidity or polypharmacy, and a higher proportion of atypical anorexia nervosa and anorexia nervosa – binge/purge subtype. EMR indications included postural tachycardia, hypotension, sinus tachycardia, hypokalaemia, hypoglycaemia, altered conscious state, and chest pain. Medical admission indications included refeeding in the setting of vital sign derangement, intravenous potassium, vital sign derangement or falls attributed to antipsychotic use, infection, abdominal pain, and self-harm.

Conclusion

Early medical assessment and intensive monitoring are recommended for older patients with greater medical multimorbidity/polypharmacy, orthostasis, or higher risk of electrolyte instability. Caution should be undertaken regarding antipsychotic use in this vulnerable population.

目的关于精神性进食障碍住院患者的急诊医学回顾（emr）和住院转院的信息有限。我们的目的是描述(i)在维多利亚州墨尔本奥斯汀医院饮食失调科（EDU）的精神科住院患者饮食失调治疗期间的电子病历记录，以及（ii）在EDU入院期间的医疗转移。方法回顾性分析18-65岁的饮食失调住院患者的病历资料，这些患者居住在Body Image &；饮食失调治疗&；于21年1月1日至23年10月30日期间入院。结果177例急诊入院患者中有33例emr， 17例转院。平均而言，emr或转院的住院患者年龄较大，医疗多重疾病或多种药物较多，非典型神经性厌食症和神经性厌食症-暴食/清除亚型的比例较高。EMR适应症包括体位性心动过速、低血压、窦性心动过速、低钾血症、低血糖、意识状态改变和胸痛。入院指征包括生命体征紊乱、静脉输钾、生命体征紊乱或因使用抗精神病药物而跌倒、感染、腹痛和自残。结论对于医学多病/多药、直立性或电解质不稳定风险较高的老年患者，建议进行早期医学评估和强化监测。在这一脆弱人群中使用抗精神病药物应谨慎。

Eating disorders (EDs) are a group of disorders characterized by altered eating behaviors and/or the emergence of behaviors pertaining to weight control. Some studies report a relationship between coping strategies adopted in the face of stress and EDs. However, the latest review on this topic was carried out in 2008 by Quiles & Terol. A systematic review of studies that have investigated the relationship between coping strategies and EDs in clinical (anorexia nervosa, bulimia nervosa, or binge eating disorder) and non-clinical populations, aged 12–25 years has been conducted. Articles in English and Spanish were selected from Web of Science and Psycinfo databases in the last 15 years. Eighteen articles were finally included in the review. The results show a higher use of negative, avoidant, and emotion-focused coping strategies in populations with eating disorders or with high scores on questionnaires; additionally, results uncovered a higher use of positive coping strategies in populations without eating disorders or with low scores on questionnaires measuring ED symptomatology.

饮食失调（EDs）是一组以改变饮食行为和/或出现与体重控制有关的行为为特征的疾病。一些研究报告了在面对压力时所采取的应对策略与ed之间的关系。然而，关于这一主题的最新综述是在2008年由Quiles &；Terol。对临床（神经性厌食症、神经性贪食症或暴食症）和非临床人群（12-25岁）应对策略与EDs之间关系的研究进行了系统回顾。英语和西班牙语的文章选自Web of Science和Psycinfo数据库中过去15年的文章。18篇文章最终被纳入综述。结果显示，在饮食失调或问卷得分高的人群中，消极、回避和情绪聚焦应对策略的使用频率更高；此外，研究结果还发现，在没有饮食失调或ED症状调查问卷得分较低的人群中，积极应对策略的使用率更高。

Background

Research supports the relation between acculturative stress and eating pathology across racially and ethnically diverse groups of women. However, relatively few studies have examined mechanisms of this link. The current study addressed these gaps by examining the potential roles of thin-, muscular-, and hourglass-ideal internalization and body dissatisfaction as mediators of the relation between acculturative stress and eating pathology among Asian, Black, and Latina women.

Methods

Adult women from across the United States (Asian N = 308; Black N = 389; Latina N = 234) completed measures of acculturative stress, body dissatisfaction, and eating pathology. Analyses investigated the direct and indirect roles of body image ideal internalization (thin-, muscular-, hourglass-) and body dissatisfaction as mediators of the relation between acculturative stress and eating pathology in each racial and ethnic group.

Results

Results identified a significant association between acculturative stress and eating pathology among all three groups of women (Asian, Black, and Latina). Also, across all groups, thin-, muscular-, and hourglass-ideal internalization mediated the relation between acculturative stress and eating pathology. Finally, body dissatisfaction mediated the relation between acculturative stress and eating pathology within the subsamples of Asian and Black women.

Conclusion

Interventions addressing eating disorder symptoms and body image could benefit from incorporating content related to acculturative stress and the impact of diverse body ideals, including thin, muscular, and hourglass, to enhance support for Black, Latina, and Asian women.

研究支持跨种族和多民族女性群体的文化适应压力和饮食病理之间的关系。然而，相对较少的研究检查了这种联系的机制。目前的研究通过检查亚洲、黑人和拉丁裔女性中瘦、肌肉和沙漏理想内化和身体不满作为异文化压力和饮食病理关系中介的潜在作用来解决这些差距。方法来自美国各地的成年女性(亚洲N = 308；黑色N = 389；Latina N = 234)完成了异文化压力、身体不满和饮食病理的测量。分析调查了身体形象理想内化（瘦型、肌肉型、沙漏型）和身体不满意作为跨文化压力和饮食病理之间关系的中介的直接和间接作用。结果发现，在所有三组女性（亚洲、黑人和拉丁裔）中，异文化压力和饮食病理之间存在显著关联。此外，在所有人群中，瘦型、肌肉型和沙漏型理想内化介导了异文化压力和饮食病理之间的关系。最后，在亚洲和黑人女性的亚样本中，身体不满介导了异文化压力和饮食病理之间的关系。结论针对饮食失调症状和身体形象的干预措施可以通过纳入与异文化压力相关的内容和不同身体理想的影响，包括瘦、肌肉和沙漏，以加强对黑人、拉丁裔和亚洲女性的支持。

Current research on eating behaviors and body image has shifted from an emphasis on disordered eating and body dissatisfaction to a broader approach that incorporates adaptive eating and positive body image. This study explored the direct relationships among body appreciation, intuitive eating, and ethnic identity in a representative sample of U.S. participants, while also examining whether ethnic identity moderated the link between body appreciation and intuitive eating. A total of 1018 U.S. adults were recruited through Qualtrics to complete an online survey. Zero-order Pearson correlations were used to analyze the direct relationships among the variables, and multiple regression was conducted to investigate the potential moderating role of ethnic identity. The findings revealed that higher levels of body appreciation were associated with greater intuitive eating, aligning with previous research and confirming this relationship within a representative U.S. sample. Furthermore, individuals with a stronger ethnic identity tended to have a slightly more positive body image and engage in intuitive eating. However, ethnic identity did not moderate the relationship between body appreciation and intuitive eating. These results highlight the importance of promoting body appreciation as a means to foster healthier eating behaviors across diverse groups. Future studies with larger and more diverse samples are needed to further examine how ethnic identity relates to body image and eating behaviors across different racial and ethnic groups. Despite its limitations, this research underscores the potential benefits of body appreciation in improving individuals' relationships with food, regardless of their background.

目前关于饮食行为和身体形象的研究已经从强调饮食失调和身体不满转向了一个更广泛的方法，包括适应性饮食和积极的身体形象。本研究在美国参与者的代表性样本中探讨了身体欣赏、直觉饮食和种族认同之间的直接关系，同时也研究了种族认同是否调节了身体欣赏和直觉饮食之间的联系。Qualtrics总共招募了1018名美国成年人来完成一项在线调查。采用零阶Pearson相关分析各变量之间的直接关系，并采用多元回归分析民族认同的调节作用。研究结果显示，对身体的欣赏程度越高，饮食的直觉性越强，这与之前的研究一致，并在一个有代表性的美国样本中证实了这一关系。此外，具有较强种族认同的个体往往具有更积极的身体形象，并从事直觉饮食。然而，种族认同并没有调节身体欣赏与直觉饮食之间的关系。这些结果强调了在不同群体中促进身体欣赏作为培养更健康饮食行为的一种手段的重要性。未来的研究需要更大、更多样化的样本，以进一步研究种族认同与不同种族和民族群体的身体形象和饮食行为之间的关系。尽管有其局限性，但这项研究强调了身体欣赏在改善个人与食物关系方面的潜在好处，而不管他们的背景如何。

Disordered eating (DE) is more prevalent among exercise and nutrition professionals (ENPs) which may be partially due to heightened levels of perfectionism. Self-actualizing strategies such as self-compassion may offer protection against DE but are not well-understood among health and wellness professionals. This cross-sectional study investigated the associations between multidimensional perfectionism (self-oriented, socially prescribed, and other-oriented perfectionism) and a two-factor model of DE: (i) weight and shape concerns and (ii) food preoccupation, among ENPs (N = 93; mean age = 33.5; 88.2 % women). Self-compassion was tested as a potential moderating factor. All three dimensions of perfectionism were positively associated with both DE factors. Self-compassion significantly moderated the relationship between self-oriented perfectionism and weight and shape concerns (b = −0.51, SE = 0.22, p = .023). Similarly, self-compassion moderated the relationship between socially prescribed perfectionism and food preoccupation (b = −0.39, SE = 0.19, p = .05). Findings suggest that self-compassion may help reduce the impact of perfectionism on DE risk in ENPs.

饮食失调（DE）在运动和营养专业人士（enp）中更为普遍，部分原因可能是完美主义水平的提高。自我实现的策略，如自我同情，可能提供对DE的保护，但在健康和保健专业人员中并没有得到很好的理解。本横断面研究调查了多维完美主义（自我导向、社会规定和他人导向的完美主义）和DE的双因素模型之间的关系：在enp中（N = 93）体重和形状关注和（ii）食物关注；平均年龄= 33.5岁；88.2%为女性)。自我同情被测试为潜在的调节因素。完美主义的所有三个维度都与两个DE因素呈正相关。自我同情显著调节自我导向型完美主义与体重和体形的关系（b = - 0.51, SE = 0.22, p = 0.023）。同样，自我同情调节了社会规定的完美主义和食物专注之间的关系（b = - 0.39, SE = 0.19, p = 0.05）。研究结果表明，自我同情可能有助于减少完美主义对enp患者猝死风险的影响。

Body positive social media content has been described as less detrimental for body image as compared to idealized body-focused social media content. However, little work has explored who finds these posts helpful. This is an important gap, as individuals who are positive towards such content are more likely to engage with it and thus find more of it in their recommended content. The aims of the study were to examine (1) reactions to body positive social media content and (2) their associations with dimensions of body image among young women. A sample of 135 undergraduate women completed an online survey. Participants viewed two different body positive social media posts and for each indicated their reactions on visual analog scales before completing measures of trait body image. One post included only text while the other featured a group of diverse women. Findings revealed that, across dimensions and posts, favorable and positive reactions were more common than negative ones. However, the group image elicited higher ratings of feeling happy, good about one's body, and ok with one's looks, and lower feelings of anxiety and embarrassment. Correlational analyses revealed trait indices of positive body image were associated with higher positive reactions to posts (happy, good about body, OK with looks) and lower negative reactions (embarrassed, anxious, bad about body, motivated to change looks), while indices of poor body image were associated with lower positive and higher negative reactions. Findings suggest body positive social media might be most useful for maintaining positive body image.

与理想化的以身体为中心的社交媒体内容相比，积极的社交媒体内容对身体形象的危害较小。然而，很少有人研究谁认为这些帖子有帮助。这是一个重要的差距，因为对此类内容持积极态度的个人更有可能参与其中，从而在他们推荐的内容中找到更多此类内容。该研究的目的是检验(1)年轻女性对身体正面社交媒体内容的反应(2)它们与身体形象维度的关联。135名女大学生完成了一项在线调查。参与者观看了两个不同的身体正面社交媒体帖子，在完成身体形象特征测量之前，每个帖子都在视觉模拟量表上表明了他们的反应。其中一篇帖子只包含文字，而另一篇则展示了一群不同的女性。调查结果显示，在各个维度和帖子中，正面和正面的反应比负面的反应更常见。然而，集体形象引发了更高的幸福感，对自己的身体满意，对自己的外表满意，以及更低的焦虑和尴尬感。相关分析表明，积极的身体形象特征指数与较高的积极反应（快乐、对自己的身体满意、对自己的外表满意）和较低的消极反应（尴尬、焦虑、对自己的身体不满意、改变外表的动机）相关，而不良的身体形象特征指数与较低的积极反应和较高的消极反应相关。研究结果表明，积极的社交媒体可能对保持积极的身体形象最有用。

Impairment in psychosocial functioning increases risk for future onset of eating disorders and a treatment that produced larger reductions in eating disorder symptoms also produced larger improvements in psychosocial functioning. However, no studies have tested whether there is a prospective reciprocal relationship between psychosocial impairment and eating disorder symptoms. Accordingly, the current study tested the hypotheses that baseline psychosocial functioning would predict future increases in eating disorder symptoms and that baseline eating disorder symptoms would predict future increases in psychosocial impairment. These questions were addressed with data from a large sample (N = 1952; M = age 19.7, SD = 5.7) of adolescent girls and young women at high risk for eating pathology due to body image concerns who were followed over a 3-year period. Findings suggest a reciprocal relationship between eating disorder symptoms and psychosocial impairment. Elevated eating disorder symptoms at baseline predicted future increases in psychosocial impairment over 3-year follow-up and elevated psychosocial impairment at baseline predicted future increases in eating disorder symptoms over 3-year follow-up. Both reciprocal effects were small-medium in magnitude (partial η² = 0.05 and 0.03, respectively). These results suggest that psychosocial impairment is a risk factor for future escalations in eating pathology and should be a target in prevention programs. Additionally, it may be useful for treatments to focus on reducing the impact of eating pathology on psychosocial functioning, which is a novel intervention target for eating disorder treatment.

社会心理功能的损害增加了未来发生饮食失调的风险，一种使饮食失调症状大幅减轻的治疗也使社会心理功能得到了更大的改善。然而，目前还没有研究测试心理社会障碍和饮食失调症状之间是否存在预期的相互关系。因此，目前的研究测试了以下假设：基线心理社会功能可以预测未来饮食失调症状的增加，而基线饮食失调症状可以预测未来心理社会障碍的增加。这些问题是用大样本的数据来解决的(N = 1952；M =年龄19.7,SD = 5.7)，这些青少年女孩和年轻女性由于对身体形象的担忧而有饮食病理的高风险，他们被跟踪了3年。研究结果表明，饮食失调症状与心理社会障碍之间存在相互关系。基线时饮食失调症状升高预示着未来3年随访中心理社会障碍的增加，基线时心理社会障碍升高预示着未来3年随访中饮食失调症状的增加。两种互反效应均为中小型（偏η2分别= 0.05和0.03）。这些结果表明，社会心理障碍是未来饮食病理升级的一个危险因素，应该成为预防计划的目标。此外，减少饮食病理对心理社会功能的影响可能有助于治疗，这是饮食失调治疗的新干预目标。

Background

Weight gain prevention is a critical component of comprehensive obesity care. Emotional eating may contribute to unwanted weight gain, increasing cardiometabolic risk factors among adults with obesity. One way to help reduce emotional eating and reduce weight gain is to provide instruction in Appetite Awareness Training (AAT).

Purpose

The purpose of this open pilot study was to examine the feasibility and acceptability of the SATISFY intervention, a 12-week intervention consisting of AAT and training from the Diabetes Prevention Program in a sample of Black and White adults with obesity, and who report emotional eating.

Methods

Eligible adults participated in 12 virtual weekly 60–90-minute group sessions. The intervention included content from AAT and the Diabetes Prevention Program. Participants also received weekly feedback on weight and eating behavior trends via a digital health platform. Participants were assessed at 0, 3 (T1), and 6 months (T2).

Results

At baseline, participants (N = 31) had a mean (±SD) age of 47.55 ± 12.41 years, BMI of 36.6 ± 6.6 kg/m² and moderate levels of emotional eating. Participants attended approximately 50 % of sessions and 77 % of participants were retained at six months. Reductions in emotional eating subscales, disinhibition, and improvements in interoceptive awareness were observed, with participants also largely maintaining their weight from T1–T3. Finally, participants reported moderate to moderately high acceptability scores.

Conclusion

The results of this study provide evidence about the feasibility, acceptability, and potential of the SATISFY program to help participants with emotional eating maintain their weight.

预防体重增加是肥胖症综合治疗的关键组成部分。情绪化进食可能会导致不必要的体重增加，增加肥胖成年人的心脏代谢风险因素。帮助减少情绪化进食和减少体重增加的一种方法是提供食欲意识训练（AAT）的指导。目的：本开放试点研究的目的是检验SATISFY干预的可行性和可接受性，这是一项为期12周的干预，包括糖尿病预防计划的AAT和培训，在患有肥胖的黑人和白人成年人中进行，并报告情绪性饮食。方法符合条件的成年人参加了12个虚拟的每周60 - 90分钟的小组会议。干预包括来自AAT和糖尿病预防计划的内容。参与者还通过数字健康平台每周收到有关体重和饮食行为趋势的反馈。在0、3 （T1）和6个月（T2）时对参与者进行评估。结果基线时，参与者（N = 31）的平均（±SD）年龄为47.55±12.41岁，BMI为36.6±6.6 kg/m2，情绪性饮食水平中等。参与者参加了大约50%的会议，77%的参与者在六个月后保留了下来。观察到情绪进食亚量表、去抑制和内感受意识的改善有所减少，参与者也在很大程度上保持了T1-T3的体重。最后，参与者报告了中等到中等高的可接受性得分。结论本研究的结果为“满足”项目帮助情绪性进食参与者保持体重的可行性、可接受性和潜力提供了证据。

Objective

Hyper-palatable foods (HPF) contain nutrient combinations that are hypothesized to maximize their rewarding effects during consumption. Due to their strong reinforcing properties, HPF are hypothesized to lead to greater energy intake within a meal. However, this premise has not been tested in free-living conditions. The current study examined the association between within-meal HPF intake and 1) measured energy intake and 2) self-reported overeating, assessed within eating occasions using smartphone-based food photography methodology.

Methods

A total of 29 participants reported food intake and eating experiences (N=345 total eating occasions) in real-time for 4 days using smartphone-based food photography methodology. HPF were identified using a standardized definition. Bayesian multilevel modeling was conducted to investigate the within-person effects of proportional calorie intake from HPF (%kcal from HPF) on total energy intake and subjective overeating. Pre-meal hunger and proportional energy intake from high energy dense (HED) foods were included as covariates.

Results

Results revealed that when participants consumed more %kcal from HPF than their average, they consumed greater total energy during eating occasions, even when controlling for pre-meal hunger and %kcal from HED foods (median β = 0.09, 95% HDI [0.02, 0.16], pd. = 99.56%). Additionally, consuming more %kcal from HPF than average was associated with greater eating despite feeling full, when controlling covariates (median β = 0.15, 95% HDI [-0.02, 0.34], pd = 96.45%).

Conclusions

The findings supported the premise that HPF themselves may yield greater energy intake and eating despite satiation, measured in real-time and free-living conditions.

目的超美味食物（HPF）含有营养组合，假设在食用过程中最大化其奖励效果。由于其强大的增强特性，高强度食物被假设会导致在一餐中摄入更多的能量。然而，这个前提还没有在自由生活的条件下得到检验。目前的研究调查了餐内高强度pf摄入与1)测量的能量摄入和2)自我报告的暴饮暴食之间的关系，使用基于智能手机的食物摄影方法在进食场合进行评估。方法29名参与者使用基于智能手机的食物摄影方法，在4天内实时报告食物摄入和饮食经历（N=345次进食）。使用标准化定义确定HPF。贝叶斯多层模型研究了从高强度食物中摄入的卡路里比例（从高强度食物中摄入的卡路里百分比）对总能量摄入和主观暴饮暴食的影响。餐前饥饿感和高能量密度（HED）食物的比例能量摄入作为协变量。结果显示，当参与者从高热量食物中摄入的%kcal高于平均水平时，即使在控制餐前饥饿感和从高热量食物中摄入的%kcal时，他们在进食时消耗的总能量也更高（中位数β = 0.09, 95% HDI [0.02, 0.16], pd）。= 99.56%)。此外，当控制协变量（中位数β = 0.15, 95% HDI [-0.02, 0.34], pd = 96.45%）时，从HPF中摄入的卡路里比平均水平多%与更大的进食量相关。研究结果支持了这样一个前提，即在实时和自由生活条件下，HPF本身可能会产生更多的能量摄入和进食，尽管有饱腹感。

Body image flexibility concerns the willingness to tolerate undesirable body-related experiences, while remaining committed to valued goals and actions, and plays an important role in the development and maintenance of the body and eating-related disorders. However, the known limitations of current assessment measures represent a major barrier to the adequate study of this construct. Recently, a novel brief psychological flexibility measure was successfully developed (Psy-Flex). The present study aimed to adapt and validate the Psy-Flex for Body Image (Psy-Flex-BI) and to explore its psychometric properties. Additionally, we aimed to support this scale as an important tool in the fields of disordered eating and body dysmorphia, by testing its ability to differentiate the severity levels of these symptoms in the general population. The study comprised 1031 participants who completed online questionnaires. The Psy-Flex-BI (6 items) was successfully adapted, and the one-dimensional factorial structure of the scale was confirmed. The scale presented robust psychometric properties, including a Cronbach's alpha of 0.89, and was invariant across sex. It also correlated in expected directions and strengths with similar constructs and maladaptive psychological indicators. Finally, Psy-flex-BI scores successfully corresponded to distinctive disordered eating and body dysmorphia symptomatology severity levels, presenting two distinct patterns supported by the literature. This data supports the scale's screening potential. Indeed, the Psy-Flex-BI is a brief and sound measure of body image flexibility, encompassing the six core ACT dimensions, and can differentiate the severity of eating and body dysmorphia symptoms in the general population.

身体形象灵活性指的是容忍不良身体相关体验的意愿，同时继续致力于有价值的目标和行动，在身体和饮食相关疾病的发展和维持中起着重要作用。然而，目前评估措施的已知局限性是对这一结构进行充分研究的主要障碍。近年来，一种新型的心理弹性测量方法（psyf - flex）被成功开发出来。本研究旨在适应和验证心理- flex身体形象（Psy-Flex- bi），并探讨其心理测量特性。此外，我们旨在通过测试该量表在普通人群中区分这些症状严重程度的能力，支持该量表作为饮食失调和身体畸形领域的重要工具。这项研究包括1031名参与者，他们完成了在线问卷调查。psyp - flex - bi（6个条目）被成功改编，并确定了量表的一维析因结构。该量表显示出强大的心理测量特性，包括Cronbach's alpha为0.89，并且在性别上是不变的。期望方向和强度与相似构念和适应不良心理指标也存在相关。最后，Psy-flex-BI评分成功对应了独特的饮食失调和身体畸形症状严重程度，呈现出文献支持的两种不同模式。这一数据支持了该量表的筛查潜力。事实上，Psy-Flex-BI是一个简单而合理的身体形象灵活性测量，包括六个核心ACT维度，可以区分一般人群饮食和身体畸形症状的严重程度。
