A Psychophysiological Investigation of Mechanisms Underlying "Feeling Fat" in Women With and WithoutBinge Eating.

"Feeling fat", the somatic experience of being overweight not fully explained by objective body weight, is considered to be an eating pathology maintenance factor. The traditional clinical understanding of "feeling fat" is based on the body displacement hypothesis, which suggests that negative emotions are projected onto the body and experienced as "feeling fat" in lieu of adaptive emotion regulation. A more recent theory suggests that "feeling fat" occurs in response to thought-shape fusion (TSF), a cognitive distortion in response to the imagined consumption of perceived fattening food. The present experimental study compared the roles of these two proposed mechanisms of "feeling fat" using self-report and psychophysiological measures. Eighty-two women (41 with binge eating, 41 control participants) self-reported "feeling fat" and had their heart rate variability (HRV), a physiological index of emotion regulation, measured before and after imagined inductions. Participants imagined either a personalized negative affective experience or consuming a preferred, so-called 'fattening' food. The TSF induction increased self-reports of "feeling fat" among participants with binge eating but not among control women. The negative affect induction did not increase self-reported "feeling fat" in either group. HRV did not significantly change in response to either induction for either group. TSF may be a more potent precursor to "feeling fat" than negative affect for individuals with binge eating. This may suggest new treatment directions, such as cognitive defusion from TSF when patients experience "feeling fat." The utility of HRV in monitoring "feeling fat" is questionable.

Eating concerns in youth with functional abdominal pain disorders.

Adolescents with functional abdominal pain (FAP) often experience pain and other gastrointestinal symptoms in the context of eating, which may place them at risk for eating disorders. This study compared disordered eating and its sequalae in adolescents with FAP to those with chronic headache. Participants in this retrospective chart review study were 270 adolescents and young adults (mean age 15.9; standard deviation [SD] = 1.63; 60% female) attending an intensive, interdisciplinary pain treatment program (IIPT), including 135 youth with FAP and an age- and gender-matched control group with a primary pain diagnosis of chronic headache. Information was extracted related to eating- and weight-related symptoms. Independent t-tests and χ2 analyses found that compared with adolescents with chronic headache, patients with FAP showed significantly more eating pathology as reflected by scores on the Eating Attitudes Test-26 (EAT-26) (p < 0.001), endorsement of pain-related restrictive eating (p < 0.01), eating disorder history (p < 0.001), and avoidant restrictive food intake disorder (ARFID) diagnoses (p < 0.001). Compared to those with chronic headache, significantly more patients with FAP had lost 10 pounds or more (p < 0.01) and a higher proportion were underweight (p < 0.001). Among all participants, a history of exclusion diets used to manage symptoms significantly increased the risk for ARFID (p < 0.001). The results of this study highlight the increased risk of eating-related concerns among youth with FAP, as well as the judicious use of exclusion diets to manage symptoms in these patients.

Low Overlap and High Heterogeneity Across Common Measures of Eating Disorder Pathology: A Content Analysis.

This study evaluated symptoms assessed in common measures of eating disorder pathology and tested overlap to evaluate the extent to which measures may be interchangeable. Six measures were included: Bulimia Test-Revised, Eating Attitudes Test-26, Eating Disorder Diagnostic Scale, Eating Disorder Examination Questionnaire, Eating Pathology Symptoms Inventory, and Questionnaire for Eating Disorder Diagnoses. Content overlap was quantitatively estimated using the Jaccard Index. Mean overlap was low (.195), likely due to the wide range of symptoms (87) assessed. The mean overlap of each measure with all others was .117 - .267, and the overlap among individual measures was .083 - .382. Implications of low overlap among measures include variable characterization of eating disorder phenotypes and the risk for lower generalizability of findings due to measurement variability.

Adaptation and Validation of the Child Eating Disorder Examination Questionnaire (ChEDE-Q) for Use in English among Adolescents in Urban India.

Eating pathology is increasingly common among Indian adolescents. However, brief validated measures of disordered eating in Indian contexts are scarce. This study adapted and validated a culturally appropriate English language version of the Child Eating Disorder Examination Questionnaire (ChEDE-Q) among 385 adolescents (mean age = 13.42 years; 47.3% girls) in urban India. Confirmatory factor analysis indicated that a two-factor eight-item solution had an acceptable fit to the data across gender: an 'Eating Concerns and Restraint' subscale and a 'Weight and Shape Concerns' subscale. Further, the questionnaire can be utilised as both a unidimensional and multidimensional tool. This allows for the computation of a total score on the primary factor of 'Child Eating Pathology', as well as the two subscales. Internal consistency of the 'Weight and Shape Concerns' subscale (α = 0.825) and 'Eating Concerns and Restraint' subscale (α = 0.649) was satisfactory. Concurrent validity was established through medium significant correlations with measures of body image and broader mental health. The results support the use of the ChEDE-Q for assessing disordered eating among urban Indian adolescents, thus providing the research community and practitioners with a measure to investigate the nature and scale of disordered eating among adolescents in India.

Elite lean athletes at sports high schools face multiple risks for mental health concerns and are in need of psychosocial support.

The combined demands on an adolescence in an elite sports high school can negatively affect mental health (eg, stress, burnout, depression, anxiety). Late adolescence is also when elite-striving athletes typically transition from junior-to-senior level programs. In addition, adolescent elite lean sports athletes have an increased risk of suffering from abnormal eating pathology. The purpose of this study was to investigate the perceived psychosocial needs that young, elite-striving lean sports athletes in sports high schools find essential for their sports careers and transition from junior-to-senior level sports. Eight Swedish elite-striving lean sports athletes (2 men and 6 women; median age 17.0 years, range: 16-18 years) participated in this study and sports represented were athletics (n = 1), gymnastics (n = 3), and wrestling (n = 4). Semi-structured interviews were performed, and data was analyzed by thematic analysis. Results showed integration, both in the present situation and for the future, as an overarching theme perceived as essential for a successful elite sports career over time. Three additional themes were also identified: (a) Psychosocial stress (combined performance demands, diminished social life, sports-related body weight demands, taboo talking about eating disorders, injuries), (b) Protective psychosocial factors (social support and psychological safety, communication and coordination school and sports, self-care/health behaviors), and (c) support needs junior-to-senior transition (career advice and mentorship, individualized support). As a result, elite-striving, lean sports athletes attending sports high schools need additional support to excel in their academic and athletic endeavors. Sports developmental programs continue to provide inadequate support before and during the junior-to-senior level transition. Similarly, despite the continued calls for reducing the stigma of mental health, athletes in sports schools still encounter barriers from coaches and peers, making the subject taboo, particularly surrounding eating pathologies.

Impairments among DSM-5 eating disorders: A systematic review and multilevel meta-analysis.

Previous research revealed that people who did not meet full DSM-IV criteria for anorexia nervosa (AN), bulimia nervosa (BN), or binge-eating disorder (BED) but met criteria for eating disorder not otherwise specified (EDNOS) display high levels of psychiatric and physical morbidity commensurate with full criteria eating disorders. The DSM-5 introduced significant changes to eating disorder diagnostic criteria, so the present study aimed to determine whether the revised diagnostic criteria better distinguish between full criteria eating disorders, and other specified feeding or eating disorder (OSFED) and unspecified feeding or eating disorder (UFED). We present a series of meta-analyses comparing eating pathology, general psychopathology, and physical health impairments among those with AN, BN, and BED, compared to those with OSFED or UFED (n=69 eligible studies). Results showed significantly more eating pathology in OSFED compared to AN, no difference in general psychopathology, and greater physical health impairments in AN. BN had greater eating pathology and general psychopathology than OSFED, but OSFED showed more physical health impairments. No differences were found between BN and purging disorder or low-frequency BN, or between BED and OSFED. Findings highlight the clinical severity of OSFED and suggest the DSM-5 criteria may not appropriately account for these presentations.

Eating disorders and non-suicidal self-injury: Cluster analysis considering eating pathology, emotion dysregulation, and negative urgency

Research on the interplay between eating pathology, emotion dysregulation and negative urgency is needed to inform intervention approaches for patients with eating disorders and non-suicidal self-injury. This study aimed to investigate the characterization of patients with eating disorders and non-suicidal self-injury considering eating pathology, emotion dysregulation and negative urgency. This cross-sectional study evaluated 73 outpatients with eating disorders and non-suicidal self-injury (14-55 years; 68 women). A cluster analysis was performed using eating pathology, emotion dysregulation and negative urgency. Differences between clusters were explored on sociodemographic/psychological variables, eating disorder diagnostics and past/current non-suicidal self-injuryengagement. Three clusters were identified. Cluster 1 (n=29) (moderate severity) was characterized by high levels of eating pathology, but moderate emotion dysregulation and negative urgency. Cluster 2 (n=29) (high severity) was characterized by the highest scores in eating pathology, emotion dysregulation and negative urgency, and included more patients with current non-suicidal self-injury. Cluster 3 (n=15) (low severity) was characterized by the lowest levels of eating pathology, emotion dysregulation and negative urgency, and included more patients with past non-suicidal self-injury. These profiles highlight the importance of emotion dysregulation and negative urgency as treatment targets for eating disorders patients with current non-suicidal self-injury.

Food Addiction Problems in College Students: The Relationship between Weight-Related Variables, Eating Habits, and Food Choices.

The concept of food addiction, characterized by a strong urge to overeat highly palatable foods, has gained increased research attention over the last decade. College students are a recognized risk group for manifesting an eating pathology and weight gain due to the changes in eating habits experienced during this period. However, there is a gap in the literature connecting food addiction with eating and weight variables in this population. Thus, the present study aims to characterize food addiction in a sample of college students and enlighten the relationship between food addiction, weight-variables, eating habits, and food choices in this population. A sample of 194 college students (89.2% females) aged between 18 and 32 years old (M = 20.85, SD = 2.78) completed a set of self-reported online questionnaires on Google Forms. Namely, a Sociodemographic and Anthropometric Questionnaire, a questionnaire on Food Choices Characterization, the Eating Habits Scale, and the Portuguese Yale Food Addiction Scale 2.0. Thirty (22.2%) participants presented food addiction problems. The logistic regression models utilized suggest that participants in the group with food addiction problems are more likely to seek clinical help to control weight, to consider that they should eat less food high in sugar, and to report lower food adequacy. In sum, this finding highlighted a connection between food addiction, weight dissatisfaction, eating habits, and food choices in college students, a population at risk for developing and retaining eating pathologies. Further research is essential to evaluate and implement interventions regarding food addiction, weight dissatisfaction, eating habits, and food choices in college students.

Social and contextual influences on eating pathology in transgender and nonbinary adults

ABSTRACT Eating pathology (EP) is reported at alarmingly high rates among transgender and nonbinary (TNB) people. The present study investigates key associations between experiences that are common in TNB populations and EP. TNB individuals located within the United States (N = 212) who self-identified as currently experiencing disordered eating or an eating disorder were recruited from social media outlets and completed an online survey that included measures of EP, discrimination-based trauma symptoms, internalized transphobia, and gender dysphoria. The average age of participants was just over 27 years old (SD = 6.22) and the majority of participants (68.9%) were nonbinary. Data were analyzed using IBM SPSS version 28 and PROCESS 4.0. Discrimination trauma [β = .27, t(211) = 3.90, p < .001] and internalized transphobia [β = .21, t(211) = 3.03, p = .003] were significant predictors of EP in a multiple regression model. Additionally, internalized transphobia partially mediated the association between discrimination trauma and EP. Findings reinforce the need for trauma-informed and multiculturally competent provision of services for TNB populations presenting with eating concerns. Results also highlight the complex role that previously unexplored variables play in the etiology of EP for TNB populations. Implications and clinical recommendations are discussed.

Food Addiction and Binge Eating Impact on Weight Loss Outcomes Two Years Following Sleeve Gastrectomy Surgery.

Emerging evidence suggest that problematic eating behaviors such as food addiction (FA) and binge eating (BE) may alter following bariatric surgery (BS) and impact weight outcomes. We aimed to examine the prevalence of FA and BE and their associations with weight outcomes 2years post-sleeve gastrectomy (SG). Forty-five women (mean age 32.4 ± 10.9years) who underwent SG and completed 24months of follow-up were evaluated prospectively at pre-, 3-, 6-, 12-, and 24-month post-SG. Data collected included anthropometrics, nutritional intake, and lifestyle patterns. The Yale Food Addiction Scale (YFAS) and the Binge Eating Scale (BES) were used to characterize FA and BE, respectively. Pre-surgery FA and BE were identified in 40.0% and 46.7% of participants, respectively. Following SG, FA and BE prevalence was 10.0%, 5.0%, 29.4%, and 14.2% (P = 0.007), and 12.5%, 4.9%, 18.4%, and 19.4% (P < 0.001) at 3, 6, 12, and 24months, respectively. Women with BE at baseline gained significantly more weight from the nadir compared to non-BE women at baseline (P = 0.009). There was no relationship between FA at baseline and weight (P = 0.090). Weight regained from the nadir positively correlated with BES scores at baseline (r = 0.374, P = 0.019). FA and BE tend to decrease during the early postoperative period, but remains in a notable rates return by 2years post-SG. Moreover, pre-surgical BE was related to higher weight-regain. Proper management pre-BS should include a comprehensive eating pathologies assessment, as these pathologies may remain or re-emerge post-surgery and lead to worse weight outcomes.

The Relationship of Food Addiction With Other Eating Pathologies and Impulsivity: A Case-Control Study.

The concept of food addiction (FA) has become central in recent years in understanding the psychological etiology of obesity. In this matched case-control study from Turkey, it was aimed to examine the prevalence of FA and related risk factors in four consecutive body mass index (BMI) categories. The case group consisted of pre-operative bariatric surgery patients with BMI over 35.0 kg/m2 (n = 40) and the control group was composed of age- and gender- matching individuals from the other categories, namely obese (n = 35), overweight (n = 40), and normal weight (n = 40). The Yale Food Addiction Scale (YFAS) and a standardized clinical interview using the DSM-5 substance use disorders criteria adopted for FA, the Eating Disorder Examination Questionnaire (EDEQ) and the Barratt Impulsivity Scale (BIS-11) were used as assessment instruments. It was found that FA was significantly associated with more serious eating pathologies, more frequent weight-cycling and earlier onset of dieting, higher impulsivity, and higher BMI. Motor and total impulsivity scores showed a positive albeit week correlation with the severity of FA but no significant correlation with BMI, indicating a relationship between impulsivity and weight gain in some but not all individuals. The severity of FA predicted the increase in BMI. Our findings suggest that FA is associated with weight gain in a group of individuals, plausibly through impulsive overeating. Emphasis on FA and its clinical implications such as addiction-based treatments may improve outcomes in obesity and facilitate health promotion.

Associations Between Defence-Style, Eating Disorder Symptoms, and Quality of Life in Community Sample of Women: A Longitudinal Exploratory Study.

Background and Aim: Eating Disorders (EDs) impact an estimated 15% of the global population and are linked to maladaptive defence-styles (coping strategies) and poorer mental health outcomes. Defence-styles have been grouped into immature, neurotic, and mature behaviours. Studies have yet to examine all three defence-styles in ED symptomatic individuals over an extended period of time. The current study aimed to investigate using converse analysis the relationships between defence-style and ED outcomes over a 5-years period.Methods: Participants (n = 216, mean age 33 years) were recruited through the Women's Eating and Health Literacy study, with the current study examining a 5-years period of two waves (year-4 and year-9). The current study tested associations over time between eating pathology (EDE-Q), psychological distress (K10), mental and physical health related quality of life (M/PHRQoL, SF-12), and defence-style (DSQ-40).Results: Mature, immature and neurotic defence-styles did not significantly change over 5 years. Over the same period, only PHRQoL significantly predicted mature defence-styles having positive effect. Both MHRQoL and PHRQoL significantly predicted immature defence-styles having positive and negative effects, respectively. Psychological distress, PHRQoL and weight concern significantly predicted neurotic defence-styles having positive effects except for psychological distress. PHRQoL, MHRQoL, restraint and eating concern significantly predicted overall eating pathology having positive effects except for PHRQoL and MHRQoL. Conversely, among the defence-style variables, over 5 years, both immature and neurotic defence-styles significantly predicted psychological distress having positive effects, immature and mature defence-styles significantly predicted MHRQoL having negative and positive effects, respectively, while only immature defence-styles significantly predicted overall eating pathology having positive effect.Conclusions: The results of the current study suggest that immaturity and neuroticism but not maturity were the defence-style variables predicting psychological distress over a 5-years period while conversely psychological distress predicted only neurotic defence styles. The findings of the current study may suggest that without intervention, mature, immature and neurotic defence-styles may largely remain immutable to significant shifts over time. Limitations in the current study included limited demographic representation. The current study is anticipated to generate considerations into treatments that could strengthen defence-styles in individuals with increased eating pathology.

Differences in Self-Reported Eating Behavior Between Night Eating Syndrome Subtypes

ObjectivesTo examine differences in binge eating (BE), food addiction (FA), and night eating syndrome (NES) symptoms between potential NES subtypes, namely eating hyperphagia (EH) and nocturnal ingestions (NI) as proposed by Allison et al. (2010). NES remains an overlooked and poorly understood condition in clinical settings, thus additional research is warranted. It was hypothesized that the EH subtype would present more severe symptoms of BE, FA, and NES symptoms than the NI subtype and control group. MethodsData were collected from adult, U.S. Mturk workers. The Night Eating Questionnaire (NEQ), Binge Eating Scale, and Yale Food Addiction Scale were used. Three groups were created using NEQ items. The EH group consisted of individuals who reported consuming >25% of daily calories after dinner with/without NI. Those who only reported NI (no EH) formed the NI group. Individuals who reported neither EH nor NI formed the control group. ResultsTotal sample consisted of 163 (48.8%) women and 171 (51.2%) men. The mean age was 36.5 (SD = 11.8). Almost half of the sample (45.5%) reported a normal body mass index (kg/m2), 30.5% were overweight and 24.0% were obese. The majority of the sample (76.0%) were white or Caucasian and 9.6% were Hispanic/Latinx. A series of analyses of variance and post-hoc comparisons were conducted to examine group differences. All groups differed significantly in terms of BE symptoms, F(2,331) = 32.01, P < .001, with the EH group (n = 97) reporting more BE symptoms than the NI (n = 69; P < .05) and control (n = 168; P < .05) groups. Similarly, all groups differed concerning FA symptoms, F(2,329) = 57.11, P < .001; after applying a Games-Howell correction, results indicated that the EH group reported more FA symptoms than the other groups. The difference in NEQ global scores between the EH and NI groups was marginally significant (P = .074), but still in the anticipated direction. ConclusionsIndividuals in the EH and NI groups had worse eating pathology than the control group, and individuals who fit within the EH subtype reported more severe symptoms of BE, FA, and global NES scores than those who only reported NI. Results from the current study support the existence of two NES subtypes and are relevant to NES assessment and treatment. Funding SourcesThe authors received no specific funding for this work.

Do women with differing levels of trait eating pathology experience daily stress and body dissatisfaction differently?

IntroductionStudies have suggested that stress predicts both body dissatisfaction (BD) and disordered eating (DE) patterns. However, the mechanisms of this process are not entirely clear and could be elucidated through further exploration in daily life.ObjectivesThe purpose of this study was to 1) explore the concurrent and lagged relationship between stress and BD in the daily life of individuals with differing levels of trait eating pathology (EP) and 2) to investigate whether maladaptive coping moderated these relationships.Methods107 female participants (mean age = 26.92) completed an online survey about stress, coping strategies and trait EP. Participants used a smartphone app to report on state stress, BD and DE six times a day for seven daysResultsIndividuals with elevated trait EP experienced a significantly higher frequency of stress events (b = 0.04). Participants’ use of maladaptive coping significantly increased state stress (b = 0.41), but was not moderated by EP. Participants’ state stress and BD measured at the same time point (concurrent assessment) were significantly related (b = 0.13). Either stress or BD at the previous time point did not significantly predict changes in the other (lagged assessment, b = 0.02, b = -0.09, respectively). The aforementioned state-based associations were not moderated by trait EPConclusionsWomen with more severe EP were found to experience stress more frequently. Maladaptive coping strategies were related to stress, but not moderated by EP. The association between stress and BD from concurrent but not lagged assessment highlights the importance of assessing and targeting momentary stress levels.DisclosureNo significant relationships.

Are they too perfect to eat healthy? Association between eating disorder symptoms and perfectionism in adolescent rhythmic gymnasts

ObjectiveEating disorders are associated with perfectionism in adults, but evidence is lacking in adolescent competitive athletes. This study examined eating disorder symptoms and perfectionism in a sample of 13–15 years old, adolescent rhythmic gymnasts. MethodsEighty-nine female rhythmic gymnasts (41 international and 48 recreational level gymnasts), completed the Eating Attitudes Tests 26 (EAT-26), the Sport Perfectionism Questionnaire (SPQ), the Social Desirability Scale (SDS) and provided information on their training. ResultsIt was found that 41.46% of the international and 14.58% of the recreational level gymnasts scored ≥20 in EAT-26. International level gymnasts also scored higher than recreational in EAT-26 (p = 0.002), and its subscales Dieting (p = 0.012) and Oral Control (p ˂ 0.001) and in the Sport Perfectionism Questionnaire (p = 0.005) and the subscales Striving for Perfectionism (p ˂ 0.001) and Personal Standards (p ˂ 0.001). No differences were found between groups in the subscales Concerns over Mistakes (p = 0.429), and Negative Reactions to Imperfection (p = 0.096). Multiple regression analysis in international level gymnasts, showed that Negative Reactions to Imperfection, body mass index and training experience accounted for 33.2% of the variance in EAT-26 (adjusted R2 = 0.332, F = 6.786, p ˂ 0.001). A negative association was observed between training experience and eating disorder symptoms in international level athletes. No association was found between the subscales of perfectionism and EAT-26 in recreational gymnasts (p ˃ 0.316). ConclusionsInternational level, adolescent rhythmic gymnasts show more eating pathology than recreational. Negative Reactions to Imperfection and BMI seem relevant for gymnasts' dieting behaviour while training experience may help adolescent athletes to cope with disturbed eating behaviours.

Reward Learning Through the Lens of RDoC: a Review of Theory, Assessment, and Empirical Findings in the Eating Disorders.

Reward-related processes may represent important transdiagnostic factors underlying eating pathology. Using the NIMH Research Domain Criteria as a guide, the current article reviews theories, behavioral and self-report assessments, and empirical findings related to reward learning in the eating disorders. Data from behavioral tasks suggest deficits in reinforcement learning, which may become more pronounced with increasing disorder severity and duration. Self-report data strongly implicate positive eating and thinness/restriction expectancies (an element of reward prediction error) in the onset and maintenance of eating pathology. Finally, self-report measures of habit strength demonstrate relationships with eating pathology and illness duration; however, behavioral task data do not support relationships between eating pathology and a propensity towards general habit development. Existing studies are limited, but provide preliminary support for the presence of abnormal reward learning in eating disorders. Continued research is needed to address identified gaps in the literature.

Help-Seeking for Eating Pathology Among Collegiate Athletes: Examining Stigma and Perfectionism as Moderating and Mediating Mechanisms

Despite elevated risk of eating pathology (EP) among athletes, utilization of EP-treatment among athletes is low. Factors that may inhibit EP-help-seeking among athletes include perceived social stigma, self-stigma, and perfectionism. Heightened stigma associated with EP and sport climates may be exacerbated by negative perfectionism characteristic of athletes and decrease intentions to seek help for EP. We tested the following moderated-mediation model among a sample of collegiate athletes (N = 201) via online questionnaires: EP indirectly relates to EP help-seeking intentions through perceived and self-stigma and these relations are conditional on negative perfectionism. EP help-seeking intentions were negatively associated with EP severity, stigma, and negative perfectionism. EP was related to eating-specific help-seeking intentions through perceived social stigma, influencing self-stigma, but this was not moderated by negative perfectionism. Targeting mental-health treatment stigma among athletes may reduce risk of untreated EP among collegiate athletes.

Low testosterone is associated with dysregulated eating symptoms in young adult men.

Extant animal and human data indicate that natural variation in circulating levels of testosterone may contribute to differential risk for dysregulated eating among males. Indeed, testosterone ablation in postpubertal male rodents results in stimulatory effects on sweet-taste preferences, and lower levels of circulating testosterone in adolescent boys have been found to predict dysregulated eating symptoms during mid-to-late puberty. Nonetheless, no prior study has examined whether lower testosterone is associated with dysregulated eating in adulthood. The current study examined this possibility. Participants were 154 young adult men (ages = 18-33) from a large Southwestern University. The Eating Disorder Examination Questionnaire, Eating Pathology Symptoms Inventory, and Loss of Control Over Eating Scale were used to assess three types of dysregulated eating symptoms: eating concerns, binge eating, and loss-of-control eating. Afternoon saliva samples were assayed for testosterone using high-sensitive enzyme immunoassays. Consistent with animal data and prior research in adolescent boys, men with lower testosterone reported significantly higher levels of dysregulated eating symptoms even after controlling for depressive symptoms, body mass index, and age. Lower testosterone concentrations might serve as a sex-specific biological factor that contributes to dysregulated eating among men.

Personality correlates of eating pathology severity and subtypes in The National Comorbidity Survey Adolescent Supplement.

We examined how personality traits are associated with eating pathology (EP) across a range of severities and symptom subtypes. The National Comorbidity Survey Adolescent Supplement (N = 10,148) was used to compare personality across severities (i.e., clinical Eating Disorders [EDs], subclinical disordered eating, preclinical weight concerns, or no weight/EP [no W/EP]), subclinical subtypes (i.e., Binge Eating Only, Binge-Purge, Binge-Restrict, Restrict-Purge, or no W/EP), and clinical subtypes (i.e., Anorexia Nervosa [AN]), Bulimia Nervosa [BN], Binge Eating Disorder [BED], internalizing disorders, or no ED or internalizing disorder) of EP. More severe EP was associated with more extreme personality trait endorsements. Impulsivity-related traits did not consistently distinguish binge eating/purging from restricting subtypes, although behavioral disinhibition differentiated adolescents with BN or BED from AN. Personality traits related to affectivity and impulsivity were more consistently associated with severity rather than subtype of EP.

Increasing help-seeking for eating pathology among collegiate athletes: An examination of a novel, customized intervention

Athletes experience elevated risk for eating pathology (EP), but evidence lower levels of help seeking for EP than the general population. Indeed, athletes experience general (e.g., stigma) and athlete-specific (e.g., “push past physical and mental pain” attitude) barriers to help-seeking. Although general mental health help-seeking interventions have improved help seeking outcomes in athlete samples, no study has developed an intervention to increase EP help-seeking among athletes. The current study examined the effects of a 75-min mental health literacy and stigma reduction intervention among 107 collegiate athletes (54.2% female) randomly assigned to an intervention or control group. All athletes completed measures of help-seeking stigma, attitudes, intentions, and behavior at baseline, post-intervention, and six-week follow-up.At post-intervention, the intervention group demonstrated significant improvements in attitudes and intentions towards seeking help for EP and general mental health, relative to the control group. No significant differences in stigma were found between the groups. At six-week follow-up, the intervention group demonstrated higher rates of help-seeking and/or referring a friend for help than the control group. However, sustained improvements in help-seeking attitudes and intentions were not present in the intervention group compared to the control group, apart from EP help-seeking attitudes. Findings support the effectiveness of a customized intervention to improve EP help-seeking variables among athletes.
