Muscle building behaviors are an understudied eating disorder (ED) symptom increasing in prevalence, especially among men. However, little is known about the cognitive ED correlates that may underlie muscle building behaviors and whether these associations differ by gender. We examined associations between cognitive ED symptoms and muscle building behaviors, and whether these associations differ between men and women. In a sample of college students (N = 258), we investigated cross-sectional associations between two core cognitive ED symptoms, body dissatisfaction and cognitive restraint, with muscle building behaviors, and whether binary gender moderated these associations. Data were analyzed using two linear regression models in which muscle building behaviors was entered as the outcome variable. In Model 1, body dissatisfaction, BMI, gender, and the interaction term of body dissatisfaction by gender were entered as predictors. In Model 2, cognitive restraint, BMI, gender, and the interaction term of cognitive restraint by gender were entered as predictors. Results of Model 1 indicated that muscle building behaviors were significantly and independently associated with body dissatisfaction and gender and the association between muscle building and body dissatisfaction was stronger for men. Results of Model 2 indicated that muscle building behaviors were significantly and independently associated with cognitive restraint and gender and the association between muscle building and cognitive restraint was stronger for men. Findings suggest that cognitive restraint and body dissatisfaction may be important prevention and intervention targets for maladaptive muscle building behaviors, particularly among men.

肌肉增强行为是饮食失调（ED）的一种未充分研究的症状，其患病率正在上升，尤其是在男性中。然而，人们对认知ED的相关性知之甚少，这可能是肌肉建设行为的基础，以及这些关联是否因性别而异。我们研究了认知ED症状和肌肉建设行为之间的联系，以及这些联系在男性和女性之间是否存在差异。在大学生样本（N = 258）中，我们调查了两种核心认知ED症状（身体不满和认知约束）与增肌行为之间的横断面关联，以及二元性别是否调节了这些关联。数据分析使用两个线性回归模型，其中肌肉建设行为作为结果变量输入。在模型1中，输入身体不满意、BMI、性别和性别对身体不满意的交互项作为预测因子。在模型2中，输入认知约束、BMI、性别和认知约束与性别的交互项作为预测因子。模型1的结果表明，增肌行为与身材不满意和性别之间存在显著且独立的相关关系，其中男性增肌与身材不满意之间的相关性更强。模型2的结果表明，增肌行为与认知约束和性别存在显著且独立的相关关系，其中男性增肌与认知约束的相关性更强。研究结果表明，认知约束和身体不满可能是预防和干预不适应肌肉建设行为的重要目标，特别是在男性中。

The first year postpartum is a sensitive time for maternal eating behaviors including emotional, external and restrained eating, which have all been associated with negative health outcomes. Furthermore, among women with a history of trauma, the stress of the postpartum period and early parenting may replicate feelings of helplessness and overwhelm experienced during childhood trauma, which may further contribute to these eating behaviors. Although evidence has shown how mothers eat during this time has long-term implications for infants' eating and health, limited research has characterized eating trajectories and associations with women's history of childhood trauma exposure during this critical period. This exploratory study examined trajectories of emotional, external, and restrained eating across the first year postpartum and delineated associations with childhood trauma. Women (N = 283) reported on emotional, external, and restrained eating across the first year postpartum (2, 6, and 12 months), and on childhood trauma exposure, postpartum depression symptoms, breastfeeding, and pre-pregnancy body mass index. Results of latent growth curve modeling revealed that mother's emotional and external eating increased while restrained eating did not change across the first year postpartum. Furthermore, mother's exposure to childhood trauma was associated with greater increases in emotional eating across the first year postpartum but not with the external and restrained eating trajectories. Findings provide valuable information on the trajectories and risk factors for postpartum eating behaviors.

College students increasingly identify as bicultural. Bicultural identity integration (BII), the extent to which an individual can effectively manage their various cultural identities, has been associated with mental health, including depressive symptoms. However, few studies have examined the association between BII and eating behaviors among racial/ethnic minority students, even though these students are at high risk for disordered eating behaviors. The primary goals of the present study were to examine the association between BII and emotional eating, and whether depressive symptoms represent an indirect pathway in the association. Asian and Latino undergraduate college students in the U.S. (N = 497; age range: 18–46 years, M = 20.81) completed online standardized questionnaires assessing demographics, BII, depressive symptoms, and emotional eating. Higher scores on BII harmony, not blendedness, were associated with fewer depressive symptoms (r = − 0.16, p < .001) and less emotional eating (r = − 0.13, p < .001). Moreover, depressive symptoms were the indirect pathway between BII harmony and emotional eating (b = − 0.15, p = .003, 95%CI boot [− 0.25, − 0.05]), but not between BII blendedness and emotional eating (b = − 0.04, p = .42, 95%CI boot [− 0.15, 0.06]). The results can help inform counseling services about the need to address cultural harmony to promote healthy eating behaviors, mental health, and well-being among bicultural undergraduate students.

越来越多的大学生认同自己是双文化人。双文化身份融合（BII），即一个人能够有效管理其各种文化身份的程度，与心理健康（包括抑郁症状）有关。然而，很少有研究探讨少数民族学生的 BII 与饮食行为之间的关系，尽管这些学生是饮食失调行为的高危人群。本研究的主要目的是探讨 BII 与情绪化进食之间的关联，以及抑郁症状是否是这种关联的间接途径。美国亚裔和拉丁裔本科大学生（人数 = 497；年龄范围：18-46 岁，平均年龄 = 20.81）填写了在线标准化问卷，对人口统计学、BII、抑郁症状和情绪化进食进行了评估。在 BII 和谐性（而非混合性）方面得分越高，抑郁症状越少（r = - 0.16，p＜0.05）。

Objective

Weight suppression refers to the difference between one's current and highest previous weight in adulthood and has been associated with development of eating pathology. Previous research has been agnostic as to whether reported weight suppression reflects deliberate weight control behavior, and few studies have assessed whether weight loss that occurs unintentionally (e.g., due to illness) is longitudinally associated with eating pathology.

Method

Undergraduates at a Canadian university (N = 661; 81.4 % female) completed three online surveys over six months. Longitudinal multilevel models examined the interaction of within-person fluctuations in weight suppression and between-person differences in weight loss intentions on binge eating, dietary restriction, and body dissatisfaction.

Results

Of participants who reported weight suppression at baseline, 47.6 % indicated that their weight loss was unintentional. Compared to participants endorsing unintentional weight suppression, participants endorsing intentional weight suppression showed greater body dissatisfaction and binge eating across the assessment period (β = 3.64, p ≤ .001 and β = 2.32, p ≤ .001). Significant within-person effects were found only for restriction, indicating that when individuals reported greater weight suppression, they also reported more restrictive eating (β = 0.89, p = .004). Contrary to hypotheses, associations between within-person fluctuations in weight suppression and disordered eating outcomes did not differ by weight loss intentions.

Discussion

Findings suggest that whether weight suppression is intentional may influence mean levels of disordered eating but may have limited influence on within-person fluctuations in weight suppression and disordered eating severity in a non-clinical sample.

目的：体重抑制是指一个人成年后当前体重与以前最高体重之间的差异，并与饮食病理的发展有关。先前的研究对于报告的体重抑制是否反映有意的体重控制行为一直是不可知论的，并且很少有研究评估无意中发生的体重减轻（例如，由于疾病）是否与饮食病理学有长期联系。方法：加拿大某大学本科生(N = 661；81.4%（女性）在六个月内完成了三次在线调查。纵向多水平模型检验了在暴饮暴食、饮食限制和身体不满方面，体重抑制的个人波动和减肥意图的个人差异之间的相互作用。结果：在报告基线体重抑制的参与者中，47.6%的人表示他们的体重减轻是无意的。与无意抑制体重的参与者相比，有意抑制体重的参与者在整个评估期间表现出更大的身体不满和暴食（β = 3.64, p≤0.001和β = 2.32, p≤0.001）。仅在限制饮食方面发现了显著的个人效应，这表明当个体报告更大的体重抑制时，他们也报告了更多的限制饮食（β = 0.89, p = 0.004）。与假设相反，体重抑制的个人波动和饮食失调结果之间的关联并不因减肥意图而异。讨论：研究结果表明，体重抑制是否有意可能影响饮食失调的平均水平，但可能对非临床样本中体重抑制和饮食失调严重程度的个人波动影响有限。

Objectives

The literature shows connections between maternal depression, children's executive function (EF), and emotional overeating (EOE). This study examined the interplay between maternal postpartum depression, EF, and EOE. We hypothesized that higher levels of postpartum depression would lead to lower inhibition and emotional control and higher levels of EOE. We also explored whether inhibition and emotional control mediate the relationship between postpartum depression and EOE.

Methods

The analysis included 297 families (49 % of children were female at birth; 82 % of caregivers were White) from a longitudinal birth cohort study in the US Midwest (N = 468). Maternal self-reports assessed postpartum depression at six weeks using the Edinburgh Postnatal Depression Scale. Children's EF at 24 months was measured with the Behavior Rating Inventory of Executive Function-Preschool Version, and EOE at 48 months was assessed using the Child Eating Behavior Questionnaire.

Results

While accounting for child gender, parent race, and education, there was a positive indirect effect of postpartum depression on EOE through children's inhibitory and emotional control difficulties. There was also a significant direct effect between postpartum depression and EOE. These results suggest that higher levels of postpartum depression in mothers may be associated with children's lower EF abilities (e.g., inhibition and emotional control), which may, in turn, lead to higher levels of EOE.

Conclusion

Early maternal depressive symptoms may have important implications for children's EF and EOE behaviors. The current findings stress the need to address symptoms of postpartum depression in mothers, even though symptoms may not reach clinical levels.

Background

Weight-based discrimination is a major public health problem. The pervasiveness of weight stigma can lead to weight-bias internalization and in turn to deleterious behaviors to change one's appearance. Weight bias internalization is linked to eating disorder behaviors, but whether this relation holds for muscle-building behaviors is unclear. Thus, the current study tested longitudinal relationships between Negative Attitudes Towards Obesity (NATO) and drive for muscularity (DFM), as well as muscle dysmorphia (MD) symptoms.

Method

Undergraduate participants (n = 1175; 79.9 % cisgender women; 87.6 % white; Mage = 19.14) completed the Eating Pathology Symptom Inventory-NATO subscale, Drive for Muscularity Scale, and the Muscle Appearance Satisfaction Scale. Multiple linear regressions, adjusting for gender, examined the longitudinal relationships between NATO, DFM, and MD symptoms.

Results

There were positive longitudinal associations between NATO and DFM, as well as negative longitudinal associations between NATO and muscularity satisfaction.

Conclusion

Greater weight stigmatizing attitudes longitudinally predicted the desire to increase muscularity and engage in muscle-building behaviors. Clinical interventions may target weight stigmatizing attitudes to reduce later symptoms of MD or DFM.

Previous literature suggests a link between insomnia symptoms and eating disorders (EDs), yet empirical data on the temporal associations between these two variables are lacking. This study aimed to explore the bidirectional associations between insomnia symptoms and EDs in a population of college students. A total of 11,010 college students were assessed initially from October 17 to 29, 2023, and again 6 months later from April 15 to 24, 2024. EDs were assessed using the Short Form of the Eating Disorder Examination Questionnaire (EDE-QS), while insomnia symptoms were measured through a three-item questionnaire addressing difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening. Our findings indicated that insomnia symptoms at baseline was significantly associated with increased odds of EDs six months later. Moreover, EDs at baseline were significantly predict insomnia symptoms at the six-month follow-up. This study identifies prospective bidirectional relationships between insomnia symptoms and EDs among college students, offering insights that may inform educational and clinical approaches to preventing and treating insomnia symptoms and EDs.

先前的文献表明失眠症状与饮食失调（EDs）之间存在联系，但缺乏关于这两个变量之间时间关联的经验数据。本研究旨在探讨大学生失眠症状与急症之间的双向关系。共有11010名大学生在2023年10月17日至29日进行了首次评估，并在6个月后的2024年4月15日至24日进行了第二次评估。EDs采用进食障碍检查问卷（ed - qs）的简短形式进行评估，而失眠症状则通过三项调查问卷进行测量，包括入睡困难、维持睡眠困难和早起。我们的研究结果表明，基线时的失眠症状与6个月后ed发生率的增加显著相关。此外，在6个月的随访中，基线ed可以显著预测失眠症状。本研究确定了大学生失眠症状和ed之间的前瞻性双向关系，为预防和治疗失眠症状和ed的教育和临床方法提供了见解。

This study aimed to determine whether the internalization of body ideals and sociocultural pressures to adhere to body ideals are associated with a greater likelihood of having probable muscle dysmorphia. Cross-sectional data from 1553 boys and men ages 15–35 from Canada and the United States were used. Multiple logistic regression analyses determined the association between the internalization of three body ideals, sociocultural pressures to adhere to body ideals from four sources, and having probable muscle dysmorphia. The odds of having probable muscle dysmorphia were significantly greater for those who internalized the muscular ideal and general attractiveness ideal. Conversely, endorsing the thin/low body fat ideal was significantly associated with lower odds of having probable muscle dysmorphia. Pressure from peers, but no other sources, showed a significant association with greater odds of having probable muscle dysmorphia. Findings expand prior research by investigating correlates of muscle dysmorphia versus muscle dysmorphia symptomatology. The strong association with internalization of the general attractiveness ideal provides new insights into how overall appearance may be highly relevant for boys and men with muscle dysmorphia, warranting future investigation.

这项研究的目的是确定身体理想的内化和坚持身体理想的社会文化压力是否与更大的可能发生肌肉畸形的可能性有关。来自加拿大和美国的1553名15-35岁的男孩和男性的横断面数据被使用。多元逻辑回归分析确定了三种身体理想的内化、坚持四种身体理想的社会文化压力和可能的肌肉畸形之间的联系。对于那些内化了肌肉理想和整体吸引力理想的人来说，可能出现肌肉畸形的几率要大得多。相反，赞成瘦/低体脂的理想与较低的可能肌肉畸形的几率显著相关。来自同伴的压力，而不是其他来源的压力，显示出更大的可能性有可能出现肌肉畸形。研究结果通过调查肌肉畸形与肌肉畸形症状的相关性扩展了先前的研究。这种与一般吸引力理想内化的强烈联系，为整体外貌如何与患有肌肉畸形的男孩和男性高度相关提供了新的见解，值得未来的研究。

Objective

This study identified mealtime challenges and emotions experienced during challenges among adolescents with anorexia nervosa (AN) or atypical anorexia nervosa (AAN) and their caregivers during the early phase of family-based treatment (FBT).

Method

Caregivers with high expressed emotion (i.e., Five-Minute Speech Sample) and their adolescents with AN/AAN completed a joint interview to discuss a recent challenging meal/snack they had together. Interviews were analyzed using thematic and content analyses. Differences in the challenges and emotions experienced between families of adolescents with AN and adolescents with AAN were explored.

Results

Twenty FBT-enrolled (M = 3.2 sessions completed; SD = 1.9) adolescents (M_age = 15.0 years, SD = 1.6) diagnosed with AN (n = 12) and AAN (n = 8) and their primary caregivers completed interviews. Six mealtime challenge themes were identified. Families with youth with AN were more likely to endorse challenges related to difficulties with FBT, food refusal, food health concerns, stress on family dynamics (i.e., lack of communication, pressure to meet expectations), and mealtime stimuli (i.e., challenging emotions). Families with youth with AAN were more likely to endorse challenges related to body, weight shape concerns and desire for control and consistency. Despite differences, both groups broadly endorsed all mealtime challenge themes.

Conclusions

Mealtimes for FBT-enrolled families are multifaceted and emotionally challenging. Families' experiences during the early phase of FBT should be assessed to provide additional support for challenges.

Objective

Studies conducted in the US indicate that exposure to trauma, and stigma related to weight are environmental factors associated with the development of disordered eating. Few studies have explored psychosocial and contextual factors surrounding disordered eating in Latin American populations. This study examined everyday discrimination, verbal weight-related abuse, adverse childhood experiences, and disordered eating across individuals seeking versus not seeking weight loss treatment in Peru.

Method

Participants (N = 420) were recruited via social media and a weight management clinic in Peru. Participants completed disordered eating, everyday discrimination, verbal weight-related abuse, and adverse childhood experiences measures.

Results

The weight loss treatment seeking group showed greater disordered eating behaviors (dietary restraint) and cognitions (body dissatisfaction, overvaluation of shape/weight) compared to the non-weight loss treatment seeking group. Increased experiences of everyday discrimination, adverse childhood experiences, and verbal weight-related abuse were associated with greater levels of disordered eating behaviors and cognitions in both samples. Weight loss treatment seeking status was not a moderator of the relationships among disordered eating behaviors and cognitions, and everyday discrimination.

Discussion

Results suggest discrimination, adverse childhood experiences, and verbal weight-related abuse are associated with eating pathology, and more disordered eating and behaviors are seen in individuals seeking or engaged in weight loss treatment. Findings highlight the importance of evaluating eating pathology for individuals reporting, or at high risk for discrimination, childhood trauma or weight-related abuse.

在美国进行的研究表明，暴露于创伤和与体重有关的耻辱是与饮食失调发展相关的环境因素。很少有研究探索拉丁美洲人群中饮食失调的社会心理和环境因素。这项研究调查了在秘鲁寻求和不寻求减肥治疗的个体之间的日常歧视、体重相关的言语虐待、不良的童年经历和饮食失调。方法通过社交媒体和秘鲁一家体重管理诊所招募参与者（N = 420）。参与者完成了饮食失调、日常歧视、体重相关的言语虐待和不良童年经历的测量。结果寻求减肥治疗组与非寻求减肥治疗组相比，出现了更多的饮食行为失调（饮食限制）和认知失调（身体不满意、身材/体重高估）。在两个样本中，日常歧视、不良童年经历和言语上与体重有关的虐待的增加与更严重的饮食行为和认知紊乱有关。寻求减肥治疗的地位并不能调节饮食失调行为和认知以及日常歧视之间的关系。讨论结果表明，歧视、不良的童年经历和体重相关的言语虐待与饮食病理有关，并且在寻求或从事减肥治疗的个体中可以看到更多的饮食失调和行为。研究结果强调了评估个人饮食病理学的重要性，这些人报告或有遭受歧视、童年创伤或体重相关虐待的高风险。
