Introduction

Food addiction (FA) shares neurobiological and behavioral mechanisms with substance use disorders, including craving and compulsive consumption despite harm and significant impairment. This study examines the prevalence of FA among treatment-seeking individuals with obesity, focusing on the contribution of emotional dysregulation, eating behaviors, and distress tolerance, to draw parallels with substance use frameworks.

Methods

This cross-sectional study included 125 individuals with obesity (BMI > 30 kg/m²) and FA diagnosis was performed using the Yale Food Addiction Scale 2.0 (YFAS-2.0). We employed the Difficulties in Emotional Regulation Scale (DERS), Distress Tolerance Scale (DTS), Interpersonal Reactivity Index (IRI) to evaluate emotional, empathy and distress measures, and performed an Exploratory Factory Analysis to evaluate the adequacy of DTS and IRI. We used LASSO regression to identify FA predictors, mediation analysis to explore indirect effects among significant variables and FA.

Results

FA was present in 37.6 % of participants, with higher prevalence among individuals with binge eating (68.4%) and grazing (54.8 %). DERS was higher in individuals with FA (MD = 25.79; 95 % C.I. [18.45, 33.13], p < .01), while distress tolerance was lower (MD = −7.15, 95 % C.I. [−10.5, −3.84], p < .01). LASSO regression identified pathological eating behaviors as the strongest predictors of FA, alongside emotional dysregulation. Mediation analysis revealed that emotional dysregulation mediated the relationship between distress tolerance and FA.

Discussion

FA represents a frequent phenomenon in obesity, often driven by low distress tolerance and poor emotional regulation, mirroring other addictions. Pathological eating behaviors may represent different phenotypic expressions of FA. Considering the relevant psychological underpinning, integrating tailored psychological interventions into obesity management may promote sustained weight management and improved outcomes.

This study explores the associations between online activities and eating disorder (ED) risk. Seven types of online activities were investigated: the usage of calorie counting and fitness apps, dating apps, social networking sites (SNS), engagement in online games, exposure to pro-ED content, cyberbullying victimization, and mukbang. A sample of 404 participants (257 females, 147 males) aged 18–48 were recruited via a Chinese online survey platform. Latent profile analysis (LPA) identified patterns of online activity, and multiple linear regression assessed the relationship between these activities and ED risk. The results showed that three distinct online activity profiles emerged: Low Risk Group, Moderate Risk Group, and High Risk Group, comprising 63.12 %, 29.70 %, and 7.18 % of the sample, respectively. The Low Risk Group exhibited the lowest ED risk and significantly lower engagement in all ED-related online activities except for social media use, compared to the other groups. The Moderate Risk Group showed a moderate level of ED risk; it did not differ significantly from the High Risk Group in most online activities, but it had higher social media use and lower rates of cyberbullying victimization. Regression analysis indicated that social media use, pro-ED content exposure, and cyberbullying victimization were significantly associated with ED risk, accounting for 43.9 % of the variance. These findings indicate that different patterns of online activity are associated with varying ED risks, and the combination of social media use and cyberbullying victimization, rather than each factor alone, appears to be correlated with higher ED risk.

Objective

Partial remission from anorexia nervosa (AN) is an understudied stage of illness, during which individuals experience improvements in behavioral/physical symptoms, but continue to experience cognitive/affective symptoms. Studying factors that may be related to recovery vs. relapse during partial remission is important given the relatively low rates of full remission in AN. Fear and avoidance of eating disorder-related stimuli are important maintaining factors in AN and require evaluation during this stage of remission.

Methods

The current exploratory study (N = 35 individuals with AN in partial remission) investigates implicit approach-avoidance bias for food and body stimuli using a computer-based, behavioral task.

Results

Participants on average had an avoidance bias for larger bodies, an approach bias for smaller bodies, and an avoidance bias for lower calorie foods.

Discussion

These findings suggest that implicit avoidance bias for larger bodies, but not higher-calorie foods, may be present during partial remission from AN. These results are consistent with current treatment models of AN, which prioritize behavioral and nutritional rehabilitation first, and persistent body image preoccupations later in treatment. Pending future research, step-down care and relapse prevention for AN during partial remission may benefit from targeting these body-related fear and avoidance biases.

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.

Sleep disruptions may be risk factors for eating disorder symptoms. However, mean estimates of sleep characteristics may not be ideal metrics, considering many individuals have irregular sleep patterns. Although variability in sleep-wake timing is associated with irregular eating patterns among individuals with eating disorders (Linnaranta et al., 2020), studies of sleep intraindividual variability (IIV) and eating pathology are limited. To fill this gap, we evaluated two indices of sleep IIV from weekdays-to-weekends and their relation to eating disorder risk. The sample was drawn from the 2018–2019 Healthy Minds Study (N = 25,879). We conducted two binary logistic regressions predicting screening positive for an eating disorder from IIV indices, adjusting for depression and mean sleep time. Greater IIV_timing (i.e., greater shifts in the timing of the sleep midpoint between weekdays and weekends) was associated with greater odds of screening positive for an eating disorder (OR = 1.049). Greater IIV_duration (i.e., greater shifts in duration of sleep between weekdays and weekends) was associated with lesser odds (OR = 0.967); however, suppressor effects of depression likely explain this finding. Greater mean duration of sleep was associated with lower odds of screening positive for an eating disorder in both models. Results are consistent with theories emphasizing the importance of sleep IIV in conceptualizing psychopathology risk; however, effect sizes were small and may have limited clinical significance. By only asking about mean sleep duration, clinicians may miss other sleep-related predictors of eating disorder psychopathology. Findings support investigating techniques to regularize sleep patterns among people with disordered eating.

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.

Introduction

The purpose of this study was to estimate disordered eating behavior (DEB) prevalence in military dependent adolescents, compare it to previous reports in the general adolescent population, and investigate whether obesity, sex and gender, or key military-specific demographics (parent in the military, parental active duty [AD] status, military branch, number of lifetime moves, number of parental deployments) are associated with higher DEB risk.

Methods

Retrospective cross-sectional study of military dependents aged 11–19 years seen in an adolescent clinic at a naval medical center for annual health maintenance visits. We manually abstracted body mass index, gender, sex, military demographics, and ChEAT-26 eating disorder screening results from electronic health records. We compared DEB prevalence to established estimates from the general adolescent population (p₀ = 0.1) and estimated DEB risk by obesity, gender, sex, and military demographics.

Results

Of 92 participants, 49 % identified as male; 9 % had obesity, 63 % had an AD parent, and 81 % were Navy families. DEB prevalence was 13 %, no different from the general population. Obesity and having a parent in the Air Force were associated with higher ChEAT-26 score. There was no significant difference in DEB risk by gender or sex.

Conclusions

DEB prevalence in military-dependent adolescents is estimated at 13 %, similar to previous reports in the general population, and obesity is associated with higher DEB risk. Military dependent males may have comparable DEB risk to females, reinforcing the importance of universal DEB screening in adolescents, and of changing the narrative of who is at risk for DEB.

Residential treatment for eating disorders is becoming increasingly common, and aims to provide individualised care within a less restrictive environment than traditional inpatient treatment settings. However, research regarding participant experiences of residential care remain limited. This study employed a mixed-methods longitudinal design to explore the experiences of individuals receiving care at Australia's first residential treatment facility for eating disorders. Seventy-eight participants completed the Your Experience of Service Survey and provided responses to open-ended questions at baseline, week 4, and discharge. Three main themes were generated from the data using reflexive thematic analysis: 1) Hopes for treatment and recovery; 2) Experiences at Wandi Nerida; and 3) Strengthening hope for recovery. Results demonstrated that participants held a generally positive view of residential treatment, particularly valuing individual psychological and nutritional therapies, meal support, nature therapies, and the presence of lived experience staff. Participants perceived residential treatment as providing holistic care that enhanced their sense of hope for recovery and supported their efforts to reclaim their identity from the eating disorder. While there was variability in each person's experience, overall, participants reported feeling respected, safe, and comfortable during their time at Wandi Nerida. These findings support literature suggesting that residential treatment offers a unique opportunity to facilitate person-centred and recovery-oriented treatment that promotes autonomy in the context of individualised, holistic and evidenced-based person-centred treatment. Nonetheless, residential treatment remains only one option along the broader continuum of care and further research is needed to optimise several aspects of this model of care.

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.
