RESUMEN
OBJECTIVE: Parental eating disorders are associated with disordered eating behaviors and psychopathology in their children, but it is not known whether parent treatment for binge-eating disorder (BED) is associated with changes in child disordered eating behaviors and weight. Benefits or the "ripple" effect of treatment on untreated family members has been described in the obesity literature but not for BED. METHOD: Participants evaluated for two randomized clinical trials for BED were screened for whether they had children. 76 parents completed baseline assessments about a school-aged child; 62 were randomized to treatment, of whom 41 completed end-of-treatment assessments about their child's eating behaviors and weight (which were not targeted in the parent treatments). RESULTS: Analyses revealed a significant effect of time on children's binge-eating frequency and perceived weight category and a significant effect of parent medication on perceived weight category. Parental change in binge eating was associated significantly with changes in child secretive eating and food hoarding. Parental change in weight was not associated significantly with change in age/sex-normed child BMI percentile, but had some associations with parent-perceived child weight category. CONCLUSIONS: Parent changes during their treatment were associated with changes in their children. Future longitudinal research is needed to examine when disordered eating emerges and clarify critical intervention timing related to children's age and parental BED. Further clinical research is also needed to assess the effectiveness of treating disordered eating at the family level. PUBLIC SIGNIFICANCE: Prior cross-sectional work has found that parents with BED are more likely to have children who engage in binge eating compared to parents without eating-disorder psychopathology. This study was an initial exploration of change in children when parents received treatment in randomized controlled trials for BED. In this study, parent changes in binge eating were associated with reduced child secretive eating and food hoarding.

OBJECTIVE: Although rates of weight discrimination are on-par with racial, ethnic, and gender discrimination, comparatively less work has examined impacts of weight-based discrimination in youth, including on disordered eating. Knowing whether experiences of weight-based discrimination, including in youth with multiply-marginalized identities, are associated with disordered eating could identify vulnerable youth and inform intervention efforts. METHOD: Youth (N = 11,875) ages 10-11 were recruited through the Adolescent Brain Cognitive Development (ABCD) study. Logistic regressions using cross-sectional data examined discrimination experiences (weight, perceived sexual orientation, race/ethnicity, national origin) and disordered eating (binge-eating, vomiting, weight-gain fear, weight self-worth). Models included race/ethnicity, age, sex, parental income, and degree of elevated weight. Raked poststratification weights were used. RESULTS: Rates of weight-based discrimination (6.2%) were similar to rates of race/ethnicity (4.4%) and sexual orientation discrimination (4.5%). Weight-based discrimination was associated with more disordered eating. Youth reporting multiple experiences of discrimination had significantly increased disordered eating compared to youth who did not report discrimination. DISCUSSION: Weight-based discrimination is common in youth and associated with disordered eating. Youth with elevated weight are more likely to be multiply marginalized and experience disordered eating. These findings suggest discrimination, including weight-based discrimination, is a critical intervention target to prevent and treat eating disorders. PUBLIC SIGNIFICANCE: Experiences of discrimination contribute to poorer health; however, weight-based discrimination is relatively understudied. Data from a large sample of youth ages 10-11 showed that youth with elevated weight reported experiencing multiple types of discrimination, and multiply-marginalized youth had increased odds of disordered eating with each additional type of discrimination. Together, this suggests that weight-based discrimination is a critical target to prevent and treat eating disorders, especially in multiply-marginalized youth.

OBJECTIVE: The objective of this study was to test the feasibility and acceptability of a treatment for weight bullying. METHOD: Participants who had experienced weight-related bullying and were currently experiencing traumatic stress were recruited and enrolled in a feasibility trial of trauma-focused cognitive behavioral therapy combined with cognitive-behavioral therapy for eating disorders (TF-CBT-WB). Thirty adolescents (aged 11-17) were determined eligible and 28 began treatment (12 weeks). RESULTS: This study demonstrated the treatment feasibility and acceptability of TF-CBT-WB for adolescents with traumatic stress following weight-bullying experiences. Overall retention and treatment satisfaction were good. Within-subjects improvements were observed for intrusion symptoms of traumatic stress, global eating-disorder severity, overvaluation of weight/shape, dissatisfaction with weight/shape, dietary restraint, and depression. Clinically-meaningful improvements were attained for several patient outcomes. Clinically-meaningful decreases in functional impairment were attained by more than half of the participants. CONCLUSIONS: Overall, this clinical trial testing TF-CBT-WB for adolescents experiencing traumatic stress following weight-bulling experiences demonstrated therapy feasibility, acceptability, and initial evidence that clinically-meaningful improvements in patient outcomes were feasible. However, some patient outcomes thought to be more central to how the youth viewed the world failed to show improvements, suggesting that additional content related to these constructs might yield greater benefit. TRIAL REGISTRATION: This pilot study was registered on clinicaltrials.gov: NCT04587752, Cognitive-Behavioral Therapy for Weight-related Bullying.
RESUMEN
BACKGROUND: Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but there is a dearth of controlled research examining pharmacotherapies as maintenance treatments for responders to initial interventions. This gap in the literature is particularly critical for pharmacotherapy for BED which is associated with relapse following discontinuation. The current study tested the efficacy of naltrexone/bupropion maintenance treatment amongst responders to acute treatments for BED. METHODS: Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested naltrexone/bupropion as maintenance treatment for responders to acute treatments with naltrexone/bupropion and/or behavioral weight-loss therapy for BED with comorbid obesity. Sixty-six patients (84.8% women, mean age 46.9, mean BMI 34.9 kg/m2) who responded to acute treatments were re-randomized to placebo (N = 34) or naltrexone/bupropion (N = 32) for 16 weeks; 86.3% completed posttreatment assessments. Mixed models and generalized estimating equations comparing maintenance treatments (naltrexone/bupropion v. placebo) included main and interactive effects of acute treatments. RESULTS: Intention-to-treat binge-eating remission rates following maintenance treatments were 50.0% (N = 17/34) for placebo and 68.8% (N = 22/32) for naltrexone/bupropion. Placebo following response to acute treatment with naltrexone/bupropion was associated with significantly decreased probability of binge-eating remission, increased binge-eating frequency, and no weight loss. Naltrexone/bupropion following response to acute treatment with naltrexone/bupropion was associated with good maintenance of binge-eating remission, low binge-eating frequency, and significant additional weight loss. CONCLUSIONS: Adult patients with BED with co-occurring obesity who have good responses to acute treatment with naltrexone/bupropion should be offered maintenance treatment with naltrexone/bupropion.

OBJECTIVE: Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but many patients who receive "evidence-based" interventions do not derive sufficient benefit. Given the dearth of controlled research examining treatments for patients who fail to respond to initial interventions, this study tested the efficacy of cognitive-behavioral therapy (CBT) for patients with BED who do not respond to initial acute treatments. METHODS: Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested 16-weeks of therapist-led CBT for non-responders to initial treatment (naltrexone/bupropion and/or behavioral therapy) for BED with obesity. Thirty-one patients (mean age 46.3 years, 77.4% women, 80.6% White, mean BMI 38.99 kg/m2 ) who were non-responders to initial acute treatments were randomized to CBT (N = 18) or no-CBT (N = 13), in addition to continuing double-blinded pharmacotherapy. Independent assessments were performed at baseline, throughout treatment, and posttreatment; 83.9% completed posttreatment assessments. RESULTS: Intention-to-treat remission rates were significantly higher for CBT (61.1%; N = 11/18) than no-CBT (7.7%; N = 1/13). Mixed models of binge-eating frequency (assessed using complementary methods) converged revealing a significant interaction between CBT and time and a significant main effect of CBT. Binge-eating frequency decreased significantly with CBT but did not change significantly with no-CBT. Since only four patients received behavioral treatment during the acute treatments, we performed "sensitivity-type" analyses restricted to the 27 patients who received pharmacotherapy during the acute treatment and found the same pattern of findings for CBT versus no-CBT. CONCLUSIONS: Adult patients with BED who fail to respond to initial pharmacological treatments should be offered CBT. PUBLIC SIGNIFICANCE: Even with leading evidence-based treatments for binge-eating disorder, many patients do not derive sufficient benefit. Almost no controlled research has examined treatments for patients who fail to respond to initial interventions. This study found that that cognitive-behavioral therapy was effective for patients with binge-eating disorder who did not respond to initial interventions, with 61% achieving abstinence.

OBJECTIVE: Binge-eating disorder involves overeating while feeling a loss of control (LOC). Emotions around LOC appear to vary; some patients fear LOC whereas others feel powerless or "resigned" to LOC. This study examined differences in psychopathology among treatment-seeking patients with binge-eating disorder categorized with fear of LOC, resignation to LOC, and no fear/resignation of LOC. METHOD: Doctoral research clinicians administered diagnostic and semistructured interviews to characterize psychopathology and establish a diagnosis of binge-eating disorder in participants (N = 382). The interview assessed fear of LOC in the past month. Further queries assessed whether, in the absence of fear of LOC, patients were resigned to LOC or had no fear/resignation. RESULTS: Patients with fear of LOC and resigned to LOC endorsed significantly greater global eating-disorder psychopathology than patients with no fear/resignation. Patients with fear of LOC reported greater distress about binge eating and greater depression than those with no fear/resignation. Patients resigned to LOC reported significantly more frequent binge-eating episodes than those with fear of LOC and no fear/resignation. Black individuals and men were more likely to report no fear/resignation than other demographic groups. DISCUSSION: This study describes a novel clinical aspect of binge-eating disorder: resignation to LOC. Findings highlight the importance of including anticipatory cognitive-affective experiences in treatment formulations and planning. Future research should examine co-occurrence of these experiences and their association with impairment. Future research should also examine how fear of LOC and resignation to LOC change during treatment and whether they predict or moderate treatment outcomes. PUBLIC SIGNIFICANCE: Adults with binge-eating disorder have anticipatory cognitive-affective experiences about loss of control (LOC) over eating (i.e., fear of LOC, resigned to LOC, no fear nor resignation of LOC). Individuals who experience fear of LOC and those who are resigned to LOC had more severe psychopathology than those without fear/resignation. Binge-eating disorder has the highest prevalence of the eating disorders; thus, findings have high public significance in guiding clinicians' treatment planning.

INTRODUCTION: Many children experience weight-based bullying (WB), when individuals are treated poorly or demeaned because of weight. WB has negative mental and physical health consequences. The current study examined how children's experiences of different forms of WB (verbal, social, physical, cyber) were associated with impaired functioning in school, social life, and family life. METHODS: Data were collected in Spring 2021. Participants (N = 224) were parents of a school-aged child and lived in the United States. Sixty percent of parents were mothers and 72% of parents self-identified as White. They completed surveys regarding weight, eating, and bullying. RESULTS: Social and cyber WB were associated with clinically significant impairment for both children and parents. Children who experienced social and physical WB were more likely to skip school, whereas physical and cyber WB were associated with skipping a particular class. All forms of bullying were associated with skipping gym class. Social and cyber WB were associated with isolating. Cyber WB was associated with all disordered eating behaviors. In addition, physical WB was associated with binge eating, social WB was associated with purging, and verbal WB was associated with secretive eating. DISCUSSION: Victims of WB experience impairment in school, social life, and family life, absenteeism, and disordered eating. It is essential to develop approaches to address WB in its various forms to identify strategies for reducing and preventing WB across various levels of influence, including peer groups, schools, and families.

OBJECTIVE: Preoccupation (excessive and constant thoughts) about shape/weight and food/eating is thought to be prominent in individuals with eating disorders but has received much less research than overt behavioral features. This study examined the significance and distinctiveness of different foci of preoccupation in individuals categorized with different forms of eating disorders and in individuals with higher weight. METHOD: Participants (N = 1,363) completed a web-based survey with established measures of eating-disorder psychopathology and depression. The current study compared preoccupation among individuals with core features of bulimia nervosa (BN; n = 144), binge-eating disorder (BED; n = 576), anorexia nervosa (AN; n = 48), and higher body weight (body mass index [BMI] ≥ 25) without eating-disorder features (higher weight [HW]; n = 595). Associations of each type of preoccupation with other eating-disorder psychopathology and depression were examined both between and within study groups. RESULTS: Preoccupation with shape/weight and with food/eating showed a graded pattern of statistically significant differences: AN and BN had higher preoccupation than BED, which was higher than HW. Within BN, BED, and AN study groups, correlation magnitudes of shape/weight and food/eating preoccupation with eating-disorder psychopathology and depression did not differ significantly. Within the HW group, shape/weight preoccupation was significantly more strongly correlated than food/eating preoccupation with overvaluation, body dissatisfaction, and depression. DISCUSSION: The preoccupation cognitive style, as well as focus, appears associated with other facets of eating-disorder psychopathology and depression. If results are confirmed among individuals with formal diagnoses, clinicians addressing maladaptive cognitions in cognitive-behavioral therapy should consider the role of preoccupation. Future research should investigate whether preoccupation predicts or moderates eating disorder treatment outcomes.

PURPOSE: Eating-disorder psychopathology is associated with self-harm behaviors. With much time spent and many social interactions taking place online, self-cyberbullying has emerged as a new form of self-harm that is digital. The current study examined digital self-harm in adults and its associations with eating-disorder psychopathology and behaviors. METHODS: Participants were adults (N = 1794) who completed an online cross-sectional survey. Participants reported whether they had ever posted mean things about themselves online, whether they had ever anonymously bullied themselves online and completed measures of eating-disorder psychopathology and disordered eating behaviors. RESULTS: Digital self-harm was reported by adults across demographic characteristics and across the lifespan, although there were some significant differences in demographic characteristics associated with reported digital self-harm. Participants who engaged in digital self-harm were younger than those denying digital self-harm. Eating-disorder psychopathology and disordered eating behaviors were significantly higher among individuals reporting digital self-harm compared with age-matched controls. CONCLUSIONS: This was the first study to examine digital self-harm among adults and the first study to examine associations of digital self-harm with eating-disorder psychopathology and disordered eating behaviors. Importantly, digital self-harm is reported by adults and therefore is not limited to youth. Our findings that digital self-harm is associated with disordered eating suggests that digital self-harm is a clinically significant topic that needs further research to inform clinical practice and clinical research. LEVEL OF EVIDENCE: Level III, Evidence obtained from well-designed cohort or case-controlled analytic studies.

PURPOSE: To examine how parents' and adolescents' weight histories were associated with parents' approach to eating/weight-related parenting and children's eating-disorder behaviors. METHODS: Participants were 502 parents (69.3% mothers, 30.7% fathers) of children 12-16 years old who completed an online survey. Parents reported their own and their child's weight status during childhood and adolescence. Parents' and children's weight histories were categorized as "weight loss," "weight stability," or "weight gain" and were examined in relation to feeding practices and eating-disorder psychopathology. RESULTS: Parents with a history of weight gain had greater personal eating-disorder psychopathology and more concerns about their child's weight than parents with weight stability or loss. They also reported greater parental overvaluation (judgment of themselves as parents according to their child's weight/shape). Children with a history of weight loss or gain were more likely to have eating-disorder behaviors than those with stable weight. Analyses revealed that results largely persisted after adjusting for child BMI-z. CONCLUSIONS: Both parent and child weight gain between childhood and adolescence were associated with eating-disorder psychopathology, eating/weight-related parenting, and feeding practices. Pediatricians and clinicians should assess weight history when considering risk for eating disorders and obesity. LEVEL OF EVIDENCE: Level III, Evidence obtained from well-designed cohort or case-controlled analytic studies.

PURPOSE: Post-operative loss-of-control (LOC)-eating is a negative prognostic indicator for long-term outcomes following bariatric surgery. Emerging research suggests that night eating might also be associated with poorer post-operative outcomes. This study examined the co-occurrence and clinical features of night eating in patients with LOC-eating following bariatric surgery. METHODS: Participants were 131 adults who sought treatment for eating/weight concerns 6 months following sleeve gastrectomy. The Eating Disorder Examination (EDE) interview (Bariatric-Surgery-Version) assessed LOC-eating, regular night eating (at least weekly), and eating-disorder psychopathology. Participants completed the Night Eating Questionnaire (NEQ), Beck Depression Inventory (BDI-II), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: Approximately, 15% met screening criteria for night-eating syndrome based on the NEQ. Greater NEQ scores were associated significantly with race, lower percent total weight loss (%TWL), and greater EDE, BDI-II, and PSQI scores. Similar results were observed when comparing groups with regular night eating (21.4%) versus without (78.6%); adjusting for race and %TWL revealed similar findings. DISCUSSION: In post-bariatric patients with LOC-eating, 15% likely had night-eating syndrome and 21.4% engaged in regular night-eating behavior. The co-occurrence of LOC-eating and regular night eating following sleeve gastrectomy may represent a more severe subgroup with elevated psychopathology, poorer sleep and %TWL. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

PURPOSE: Nonhomeostatic drives (e.g., reward and negative emotion) for eating are associated with weight gain over time. Higher average and lower intraindividual variability in physical activity (PA) levels are positively associated with health and weight outcomes, but have not been evaluated in relation to nonhomeostatic eating. The aim of this paper is to examine the associations between PA and nonhomeostatic drives for eating. The hypotheses were that average levels of and consistency in PA would be negatively correlated with nonhomeostatic eating. METHODS: Adult participants (N = 432) were recruited online and asked to report objectively measured PA using commercially available PA monitors for the previous 7 days and to complete self-report measures of reward-driven and emotional eating. RESULTS: Average daily steps (M = 6519.36) were negatively associated with emotional eating, but were not significantly related to reward-driven eating. Intraindividual variability in steps (M = 2209.85) was not associated with either type of nonhomeostatic eating. Adjusting for relevant covariates (e.g., age, BMI, gender), average daily step count was negatively associated with emotional eating (p = 0.01) but not reward-driven eating (p = 0.31) and variability in step counts was positively associated with reward-driven eating (p = 0.04) but not emotional eating (p = 0.52). CONCLUSION: The results suggest that greater average levels and lower variability in PA are related to lower nonhomeostatic eating; thus, complex associations between PA and eating exist, and may impact weight and outcomes of treatment related to eating and weight. LEVEL OF EVIDENCE: V, cross-sectional correlation study.

BACKGROUND: Psychiatric comorbidity is common in binge-eating disorder (BED) but effects on treatment outcomes are unknown. The current study aimed to determine whether psychiatric comorbidity predicted or moderated BED treatment outcomes. METHODS: In total, 636 adults with BED in randomized-controlled trials (RCTs) were assessed prior, throughout, and posttreatment by doctoral research-clinicians using reliably-administered semi-structured interviews, self-report measures, and measured weight. Data were aggregated from RCTs testing cognitive-behavioral therapy, behavioral weight loss, multi-modal (combined pharmacological plus cognitive-behavioral/behavioral), and/or control conditions. Intent-to-treat analyses (all available data) tested comorbidity (mood, anxiety, 'any disorder' separately) as predictors and moderators of outcomes. Mixed-effects models tested comorbidity effects on binge-eating frequency, global eating-disorder psychopathology, and weight. Generalized estimating equation models tested binge-eating remission (zero binge-eating episodes during the past month; missing data imputed as failure). RESULTS: Overall, 41% of patients had current psychiatric comorbidity; 22% had mood and 23% had anxiety disorders. Psychiatric comorbidity did not significantly moderate the outcomes of specific treatments. Psychiatric comorbidity predicted worse eating-disorder psychopathology and higher binge-eating frequency across all treatments and timepoints. Patients with mood comorbidity were significantly less likely to remit than those without mood disorders (30% v. 41%). Psychiatric comorbidity neither predicted nor moderated weight loss. CONCLUSIONS: Psychiatric comorbidity was associated with more severe BED psychopathology throughout treatment but did not moderate outcomes. Findings highlight the need to improve treatments for BED with psychiatric comorbidities but challenge perspectives that combining existing psychological and pharmacological interventions is warranted. Treatment research must identify more effective interventions for BED overall and for patients with comorbidities.
RESUMEN
OBJECTIVE: Some parental feeding practices are associated with pediatric disordered eating and weight status. Existing research, however, has focused on maternal feeding practices in co-parent households. Single parents and fathers are notably understudied in this area. The current study examined associations of parental feeding practices with child disordered eating behaviors and weight, and compared associations between single mothers and fathers with a matched sample of co-parenting mothers and fathers. METHOD: Parents (N = 524) of youth between 5 and 16 years completed an online survey that included measures of parental feeding practices and unhealthy eating/weight-related parenting practices. Co-parents were matched to each single parent based on gender, race, ethnicity, education level, age, and BMI. RESULTS: Single parents reported significantly greater concern about their child's weight, eating and shape, and reported engaging in more restraint and restriction of their child's eating, as well as having more perceived responsibility of their child's eating than caregivers in co-parent households. Children of single parents were significantly more likely to engage in secretive eating. DISCUSSION: Associations between single parents' feeding practices and child weight and disordered eating parallel the broader literature. There were differences between single mothers and fathers and co-parenting mothers and fathers, particularly in their report of their unhealthy eating/weight-related parenting practices. Such differences may influence children's longer-term eating behaviors and weight status. Further research on single-parent households is needed, including longitudinal and epidemiological studies.

OBJECTIVE: To examine the distinctiveness and significance of two body image constructs, dissatisfaction with weight and shape and overvaluation of weight and shape, with respect to eating disorder psychopathology, weight, and depression in White and Latinx/Hispanic men and women. METHODS: Participants were White (n = 1,941) and Latinx/Hispanic (n = 568) adults living in the United States who completed an online battery of established measures of body image, eating disorder psychopathology and behaviors, and depression. RESULTS: Two body image constructs, dissatisfaction with weight and shape and overvaluation of weight and shape, were related to each other but showed some important distinctions in their associations with eating- and weight-related variables. Significantly greater proportions of White than Latinx/Hispanic individuals reported co-occurring dissatisfaction and overvaluation, and significantly greater proportions of Latinx/Hispanic than White individuals reported dissatisfaction alone. Ethnicity moderated the association of dissatisfaction and overvaluation with body mass index (BMI), and the association of overvaluation with depression. Ethnicity also had a main effect on binge-eating frequency. CONCLUSIONS: Dissatisfaction and overvaluation were distinct among both Latinx/Hispanic and White individuals. However, associations with eating- and weight-related variables varied between ethnicities, suggesting a need for further research on the influence of cultural variables on body image and eating disorder psychopathology.

OBJECTIVE: Internalized weight bias (IWB), or negative weight related self-evaluation, is associated with eating-disorder psychopathology and common among patients seeking bariatric surgery, but little is known about the clinical presentation of IWB post-operatively. This study examined IWB and clinical correlates among adult patients with loss-of-control (LOC) eating post-sleeve gastrectomy surgery. METHODS: Participants (N = 145) were sleeve gastrectomy patients seeking treatment for eating/weight concerns and experiencing regular LOC eating approximately 6 months following surgery. Eating-disorder features were assessed with the Eating Disorder Examination-Bariatric Surgery Version interview (EDE-BSV) and participants completed established measures assessing IWB, depression, and mental and physical components of quality of life. RESULTS: IWB was not associated significantly with percent excess weight loss, age, or gender, but White participants reported significantly greater IWB than Non-White participants. IWB was significantly associated with greater eating-disorder psychopathology, depression, and lower perceived mental quality of life. Hierarchical regression analysis revealed that IWB significantly predicted variance in eating-disorder psychopathology above and beyond other related variables. CONCLUSIONS: Findings suggest that IWB is common and associated with a range of heightened eating-disorder and psychosocial difficulties among patients experiencing LOC eating following bariatric surgery. Future research exploring the longitudinal post-operative prognostic significance of IWB is recommended.

OBJECTIVE: This study examined whether sex predicted and/or moderated treatment outcomes among men and women who participated in binge-eating disorder (BED) randomized controlled trials (RCTs). METHOD: Data were aggregated from RCTs performed at one medical center. RCTs tested cognitive-behavioral therapy, behavioral weight loss, multimodal treatment, and/or control conditions. Participants were 660 adults, both men (n = 170) and women (n = 490), with Diagnostic and Statistical Manual-fourth edition (DSM-IV)-defined BED. Doctoral-level research-clinicians assessed participants using structured interviews and established self-report measures of eating-disorder psychopathology and depression, and measured height and weight. Assessments occurred at baseline, throughout treatment, and at post-treatment. RESULTS: Sex was not a significant moderator of any treatment outcomes. Mixed models revealed sex had a main effect: men had lower eating-disorder psychopathology and lost more weight than women over the course of treatment. DISCUSSION: Both epidemiological and RCT studies report disparities in treatment-seeking between men and women with BED. Despite this, men have comparable or better treatment outcomes compared with women, including significantly greater weight loss. Thus, disseminating evidence-based BED treatments is promising for both men and women. Additional research is necessary, however, to understand treatment effects-including other predictors and moderators of outcomes-across diverse providers, treatment settings, and patient groups.

Parents are key to children's health because they can influence children's eating behavior and body image and can make health-related decisions for children. Despite their influence, research on parents' opinions about parenting practices related to weight and eating is limited. Experimental vignettes examined parents' perceptions of parent-child interactions around body image, eating, and weight loss. We manipulated vignette-child weight (healthy-weight, overweight) and communication tone (positive, negative, neutral) to assess their influence on parents' perceptions. Parents (N = 233, 27.5% fathers, 72.5% mothers) were randomly assigned to read one of six vignettes. When the vignette-child had overweight, parents were more likely to recommend seeking help for body image and that the vignette-parent should choose the restaurant food order. Parents were less opposed to commenting on the vignette-child's weight when tone was positive. Parents were more likely to recommend weight-loss efforts that could be implemented by the family rather than those requiring professional assistance. This study is among the first to examine parents' opinions about parenting practices related to weight and eating using an experimental design. Findings might inform future research and continued work on prevention and treatment applications to help align parents' existing opinions about weight and eating with evidence-based health-promoting strategies.

BACKGROUND: Food insecurity occurs when access to food is limited by financial hardship. Yet, paradoxically, food insecurity is associated with overeating, with emerging evidence that it may be related to disordered eating. A recent report found that food insecurity was associated with binge-eating disorder (BED), but it is not yet known whether food insecurity is also associated with bulimia nervosa (BN). METHODS: Participants were 873 respondents recruited online who completed a battery of established measures and were categorized into three study groups: healthy-weight (HW), BED, and BN. Hierarchical logistic regressions evaluated the extent to which low and very low food security were associated with BN compared with HW and BED study groups. RESULTS: Low and very low food security were both associated with increased likelihood of BN group membership compared with HW but not BED. CONCLUSIONS: Our findings suggest that food insecurity is associated with BN and also suggest that food insecurity's association with BN is similar to that for BED. These findings highlight the need for greater clinical and research attention to associations between food insecurity and eating disorders that include binge eating to inform eating-disorder prevention and treatment.

OBJECTIVE: Secretive eating is characterized by eating furtively and concealing the act and evidence of eating. Among youth, secretive eating is common and associated with eating-disorder psychopathology. Yet, secretive eating among adults, including adults with eating disorders, is relatively unexplored. METHOD: We assessed secretive eating among treatment-seeking adults with binge-eating disorder (BED) and examined demographic and clinical characteristics of patients with and without secretive eating. Patients (N = 755) were assessed for BED, eating-disorder psychopathology, and depression by trained doctoral clinicians using established interviews and self-report measures; height and weight were measured. RESULTS: Overall, 54% of patients reported secretive eating distinct (i.e., separate) from objective binge-eating episodes (OBEs). A significantly greater proportion of women than men endorsed secretive eating; age, race, and education did not significantly differ. Patients with and without secretive eating did not significantly differ in body mass index (BMI), OBEs, overeating episodes, or restraint. Patients with secretive eating endorsed significantly more subjective binge-eating episodes, greater eating concerns, shape concerns, and weight concerns and had higher depression scores than patients without secretive eating. Patients with secretive eating were significantly more likely to have overvaluation of shape/weight than patients without secretive eating. Results remained the same after adjusting for sex, race, and BMI. DISCUSSION: Findings suggest that, among patients with BED, secretive eating reflects greater eating-disorder psychopathology but not increased frequency of OBEs or greater BMI. Understanding secretive eating can to inform determination of eating-disorder severity contribute to treatment formulation and planning.
