Elwyn R, Williams M, Smith E, Smith S. Two identical twin pairs discordant for longstanding anorexia nervosa and OSFED: lived experience accounts of eating disorder and recovery processes. J Eat Disord 2024; 12:127. [PMID: 39223672 PMCID: PMC11367789 DOI: 10.1186/s40337-024-01078-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 08/02/2024] [Indexed: 09/04/2024] Open
Abstract
Research into the risk of anorexia nervosa (AN) has examined twin pairs to further the understanding of the contributions of genetics, trait inheritance, and environmental factors to eating disorder (ED) development. Investigations of twin experiences of EDs have been biologically-based and have not considered the qualitative, phenomenological aspects of twin experiences. A gap in the literature exists regarding understanding of discordant twins with EDs. This research was developed in response, with the aim to deepen understanding of AN in discordant twins and to create novel ideas for further research and testing. The case studies presented in this article provide lived experience insights of two identical discordant twin pairs: one twin pair discordant for longstanding AN and one twin pair discordant for 'atypical' AN (the twin with AN has recovered). The perspectives and experiences of each co-twin (one with AN and one without) explore a number of factors that may have contributed to twin discordance in these cases, and how each twin has responded to the impact of AN in their lives. Through use of first-person accounts in case study presentation, this article centres social justice values of lived experience leadership and involvement in research. This article aims to extend current knowledge and understanding of EDs in discordant twins, particularly regarding risk for ED development, ED duration, diagnosis and treatment, and recovery processes.

Oculomotor behaviors in youth with an eating disorder: findings from a video-based eye tracking task. J Eat Disord 2024; 12:121. [PMID: 39169420 PMCID: PMC11337776 DOI: 10.1186/s40337-024-01084-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Accepted: 08/10/2024] [Indexed: 08/23/2024] Open
Abstract
BACKGROUND The oculomotor circuit spans many cortical and subcortical areas that have been implicated in psychiatric disease. This, combined with previous findings, suggests that eye tracking may be a useful method to investigate eating disorders. Therefore, this study aimed to assess oculomotor behaviors in youth with and without an eating disorder. METHODS Female youth with and without an eating disorder completed a structured task involving randomly interleaved pro-saccade (toward at a stimulus) and anti-saccade (away from stimulus) trials with video-based eye tracking. Differences in saccades (rapid eye movements between two points), eye blinks and pupil were examined. RESULTS Youth with an eating disorder (n = 65, Mage = 17.16 ± 3.5 years) were compared to healthy controls (HC; n = 65, Mage = 17.88 ± 4.3 years). The eating disorder group was composed of individuals with anorexia nervosa (n = 49), bulimia nervosa (n = 7) and other specified feeding or eating disorder (n = 9). The eating disorder group was further divided into two subgroups: individuals with a restrictive spectrum eating disorder (ED-R; n = 43) or a bulimic spectrum eating disorder (ED-BP; n = 22). In pro-saccade trials, the eating disorder group made significantly more fixation breaks than HCs (F(1,128) = 5.33, p = 0.023). The ED-BP group made the most anticipatory pro-saccades, followed by ED-R, then HCs (F(2,127) = 3.38, p = 0.037). Groups did not differ on rate of correct express or regular latency pro-saccades. In anti-saccade trials, groups only significantly differed on percentage of direction errors corrected (F(2, 127) = 4.554, p = 0.012). The eating disorder group had a significantly smaller baseline pupil size (F(2,127) = 3.60, p = 0.030) and slower pro-saccade dilation velocity (F(2,127) = 3.30, p = 0.040) compared to HCs. The ED-R group had the lowest blink probability during the intertrial interval (ITI), followed by ED-BP, with HCs having the highest ITI blink probability (F(2,125) = 3.63, p = 0.029). CONCLUSIONS These results suggest that youth with an eating disorder may have different oculomotor behaviors during a structured eye tracking task. The oculomotor behavioral differences observed in this study presents an important step towards identifying neurobiological and cognitive contributions towards eating disorders.

Abstract
BACKGROUND Co-production is the collaboration between researchers and the lived experience community in designing, conducting and sharing research. The importance of co-production is increasingly advocated in both the autism and eating disorder fields. Despite this, there remains a lack of clarity at how to define, apply and conduct ethical co-production. Understanding common challenges and what we can do to overcome these challenges are integral to ensuring ethical and meaningful research with Autistic people with an eating disorder. The current study therefore explored: What are the barriers and facilitators to ethical co-production with Autistic people with an ED? METHODS Five workshops were conducted with 30 collaborators exploring barriers and facilitators to ethical co-production. Synchronous (online workshops) and asynchronous (offline discussion forum) data was analysed using thematic analysis. Themes were co-produced by a neurotypical and Autistic researcher with lived/living experience of an eating disorder. RESULTS Four themes were identified that explored barriers to ethical co-production: unequal partnerships, the inaccessibility of research, excluded by diagnoses and communication differences. Three themes were identified with regards to facilitators of ethical co-production: shared power (with sub-themes relationships, not roles and creative compensation), clarity and transparency and autism-affirming approaches. DISCUSSION Conducting ethical co-production with Autistic people with eating disorders has the potential to generate meaningful research that can be translated into improving the lives of the Autistic and eating disorder community. To achieve this, co-production teams should strive towards shared power and long-term relationships, adapting for communication differences and preferences and operating firmly within an autism-affirming framework. It is hoped that study findings will inspire collaboration, discussion and novel, translatable research.

Abstract
Affective symptoms (e.g., depression, anxiety, shame) are a potent risk factor for binge eating. However, less is known on the role of loneliness as a moderator of affective symptoms and binge eating. This objective of the current study was to investigate main effects and interactions of affective symptoms and loneliness in relation to binge eating in college women. A sample of 556 undergraduate women completed self-report questionnaires of affective symptoms, loneliness, and binge eating. Results revealed significant interactions between each affective symptom variable and loneliness in relation to binge eating, such that loneliness strengthened the positive association of affective symptoms and greater binge eating. The findings of this study demonstrate an important role of loneliness to binge eating among college women, especially those with underlying affective vulnerabilities. More theoretical and treatment-oriented work on the role of loneliness in binge eating is needed to understand mechanisms and interventions/preventions.

Abstract
PURPOSE This study investigated the association between childhood eating behaviors and cortical morphology, in relation to sex and age, in a community sample. METHODS Neuroimaging data of 71 children (mean age = 9.9 ± 1.4 years; 39 boys/32 girls) were obtained from the Nathan Kline Institute-Rockland Sample. Emotional overeating, food fussiness, and emotional undereating were assessed using the Children's Eating Behavior Questionnaire. Cortical thickness was obtained at 81,924 vertices covering the entire cortex. Generalized Linear Mixed Models were used for statistical analysis. RESULTS There was a significant effect of sex in the association between cortical thickness and emotional overeating (localized at the right postcentral and bilateral superior parietal gyri). Boys with more emotional overeating presented cortical thickening, whereas the opposite was observed in girls (p < 0.05). Different patterns of association were identified between food fussiness and cortical thickness (p < 0.05). The left rostral middle frontal gyrus displayed a positive correlation with food fussiness from 6 to 8 years, but a negative correlation from 12 to 14 years. Emotional undereating was associated with cortical thickening at the left precuneus, left middle temporal gyrus, and left insula (p < 0.05) with no effect of sex or age. CONCLUSIONS Leveraging on a community sample, findings support distinct patterns of associations between eating behaviors and cortical thickness, depending on sex and age.

Abstract
OBJECTIVE Early adolescence is marked by elevated psychopathology, including disrupted eating attitudes and behaviors. Reward processing is an identified mechanism in portending eating pathology, that is, aberrant reward responsivity may contribute to disrupted reward-seeking behaviors (e.g., food consuming). This literature has focused on adults or mid-to-late adolescents, with little work done on early adolescence. We examined the linkages between reward feedback processing, indexed by event-related potentials (ERPs), and changes of emerging disordered eating in community-dwelling early adolescents. METHOD At T1, 115 youths (66 girls, mean/SD age = 11.00/1.16 years) completed an EEG monetary reward Doors task. Youths completed the Eating Disorder Examination-Questionnaire Short at T1 and ~6 months (T2) and ~12 months (T3) after T1. In the ERP data, we isolated a reward positivity (RewP) and a late positive potential (LPP) via principal component analysis. We applied multilevel modeling to examine whether baseline ERPs interacted with Time in predicting disordered eating and whether these interactions varied by sex. RESULTS We found a significant Time × LPP interaction in girls but not boys. Among girls, only those with a smaller LPP toward the losses (versus wins), which might reflect suboptimal evaluation and regulatory processes in undesired situations, showed increases in disordered eating from T1 to T3. DISCUSSION We provided preliminary yet novel evidence concerning the prospective associations between reward processing and changes of disordered eating in early adolescents. Future studies along this line will be critical for understanding the early mechanisms of eating pathology, identifying youths at risk, and developing prevention strategies.

Abstract
OBJECTIVES This study examined the mediating effect of psychological distress and mindful eating behaviors between orthorexia nervosa and academic self-efficacy among Lebanese university female students. METHODS A total of 769 female participants enrolled in this cross-sectional study (mean age 21.58 ± 3.20 years). A self-administered questionnaire was distributed among university female students. The questionnaire consisted of Mindful Eating Behaviors Scale, ORTO-R, Depression Anxiety Stress Scale, and Arabic version of Academic Self-Efficacy Scale. RESULTS The results showed that psychological distress fully mediated the association between orthorexia nervosa and academic self-efficacy; higher orthorexia nervosa was significantly associated with less psychological distress (β= -0.31, p =.05), with more psychological distress significantly associated with lower academic self-efficacy (β= -0.32, p =.09). Focused eating fully mediated the association between orthorexia nervosa and academic self-efficacy; higher orthorexia nervosa was significantly associated with less focused eating (β=-0.09, p =.04), with more focused eating significantly associated with better academic self-efficacy (β = 1.40, p =.10). Orthorexia nervosa was not directly associated with academic self-efficacy in both models. CONCLUSION This study shed light on important connections between orthorexia nervosa, psychological distress, mindful eating behaviors, and academic self-efficacy within the Lebanese context. The findings will have practical implications for both educational institutions and healthcare providers striving to support young female adults' overall well-being and academic success.

Abstract
BACKGROUND Sexually polymorphic cognition (SPC) results from the interaction between biological (birth-assigned sex (BAS), sex hormones) and socio-cultural (gender identity, gender roles, sexual orientation) factors. The literature remains quite mixed regarding the magnitude of the effects of these variables. This project used a battery of classic cognitive tests designed to assess the influence of sex hormones on cognitive performance. At the same time, we aimed to assess the inter-related and respective effects that BAS, sex hormones, and gender-related factors have on SPC. METHODS We recruited 222 adults who completed eight cognitive tasks that assessed a variety of cognitive domains during a 150-min session. Subgroups were separated based on gender identity and sexual orientation and recruited as follows: cisgender heterosexual men (n = 46), cisgender non-heterosexual men (n = 36), cisgender heterosexual women (n = 36), cisgender non-heterosexual women (n = 38), gender diverse (n = 66). Saliva samples were collected before, during, and after the test to assess testosterone, estradiol, progesterone, cortisol, and dehydroepiandrosterone. Psychosocial variables were derived from self-report questionnaires. RESULTS Cognitive performance reflects sex and gender differences that are partially consistent with the literature. Interestingly, biological factors seem to better explain differences in male-typed cognitive tasks (i.e., spatial), while psychosocial factors seem to better explain differences in female-typed cognitive tasks (i.e., verbal). CONCLUSION Our results establish a better comprehension of SPC over and above the effects of BAS as a binary variable. We highlight the importance of treating sex as a biological factor and gender as a socio-cultural factor together since they collectively influence SPC.

Abstract
Introduction The gender difference of binge eating behavior been highlighted by previous studies. However, psychological mechanisms underlying the gender difference of binge eating behavior remain unclear. This study addressed this issue from a sociocultural perspective. Methods Firstly, we investigated the mediation effect of body dissatisfaction on the gender difference of binge eating behavior. Secondly, we examine the serial mediating role of body dissatisfaction and self-acceptance in gender differences of binge eating behavior. Here, we analyzed data from 703 Chinese university students using SPSS 26.0 and SPSS PROCESS. Results In Chinese culture, body dissatisfaction and self-acceptance independently or through a serial way mediate the gender differences in binge eating behaviors. Discussion We discussed the implications and limitations of the present study.

Abstract
This study examines the association between gender expression, weight status, and the risk of experiencing eating disorders among gender-diverse adults assigned male at birth living in Bangkok, Thailand. Participants completed self-administered questionnaires to provide demographic data and anthropometric measures, and an Eating Attitude Test-26 (EAT-26) to determine the risk of experiencing eating disorders. The associations between gender expression, weight status, and the risk of experiencing eating disorders were analyzed using multivariable logistic regression models. No significant differences were observed in weight-related variables based on gender expression. Participants self-described as feminine/androgynous had lower odds of experiencing a high risk of eating disorders compared to those self-described as masculine (odds ratio (OR) = 0.49; 95% confidence interval (95% CI) = 0.27, 0.88). A higher body mass index (BMI) (OR = 1.07; 95% CI = 1.01, 1.14) and BMI discrepancy (OR = 1.13; 95% CI = 1.03, 1.24) were associated with higher odds of engaging in extreme weight-control behaviors. The risk of experiencing eating disorders among Thai gender-diverse adults assigned male at birth could differ across gender expression and weight status. Further research is needed to expand the understanding of these relationships and develop tailored intervention programs to mitigate the risk.

Abstract
Eating disorders have early origins, and there could be a continuum between childhood eating behaviors, such as overeating, and long-term disordered eating, but this remains to be shown. BMI, desire for thinness and peer victimization could influence this continuum, but their interactions are unknown. To fill this gap, the study used data from the Quebec Longitudinal Study of Child Development (N = 1511; 52% girls), in which 30.9% of youth presented a trajectory associated with high disordered eating from 12 to 20 years. The results support an indirect association between overeating at age 5 and disordered eating trajectories, with different mediation processes observed between boys and girls. The findings underscore the importance of promoting healthy body images and eating behaviors among youths.
