A qualitative assessment of provider-perceived barriers to implementing family-based treatment for anorexia nervosa in low-income community settings. J Eat Disord 2024; 12:51. [PMID: 38664842 PMCID: PMC11045456 DOI: 10.1186/s40337-024-01008-w] [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: 03/04/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Family-based treatment (FBT) is a front-line empirically supported intervention for adolescent anorexia nervosa, but it is often inaccessible to families from lower income backgrounds, as it is most typically available in specialty research and private practice settings. In preparation for a pilot trial of FBT delivered in the home setting, this study qualitatively examined provider perceptions of implementing FBT in lower-income communities. METHODS Eating disorder clinicians working in community clinics (therapists, medical doctors, dietitians, and social workers; n = 9) were interviewed about their experiences using FBT. Interview transcripts were analyzed both deductively, using an approach consistent with applied thematic analysis, and inductively, using the Replicating Effective Programs implementation framework, to examine barriers to FBT implementation. RESULTS Prevailing themes included concern about the time and resources required of caregivers to participate in FBT, which may not be feasible for those who work full time, have other caregiving demands, and/or lack family support. Psychosocial problems outside of the eating disorder, such as food insecurity, other untreated mental health concerns (in themselves or other family members), or externalizing behaviors on the part of the adolescent, were also discussed as barriers, and participants noted that the lack of cohesive treatment teams in the community make it difficult to ensure continuity of care. CONCLUSION Findings from this qualitative study indicate the need to address systemic socioeconomic barriers to improve the efficacy of implementation of FBT in the community and to understand how provider perceptions of these barriers influence their uptake of FBT.

Association between parental resource depletion and parent use of specific food parenting practices: An ecological momentary assessment study. Appetite 2024; 199:107368. [PMID: 38643902 DOI: 10.1016/j.appet.2024.107368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 04/17/2024] [Accepted: 04/19/2024] [Indexed: 04/23/2024]
Abstract
The resource depletion model proposes that self-control is a limited resource that may become depleted after repeated use. This study aimed to improve our understanding of the correlates of resource depletion in parents, examine the association between resource depletion and use of coercive food parenting practices, and explore the relationship between resource depletion and stress. Children aged 5-9 and their parents (n = 631 dyads) were recruited from primary care clinics in a large metropolitan area in the United States in 2016-2019. Ecological momentary assessment was carried out over seven days with parents. Frequency tabulations and descriptive statistics were calculated to examine the overall, between-participant, and within-participant frequency of resource depletion, stress, and coercive food parenting practices. Resource depletion was higher among mothers (as compared to fathers) and native born participants (as compared to immigrants). Resource depletion was found to decrease significantly with each increase in household income level and perceived co-parenting support was negatively associated with resource depletion. Greater resource depletion earlier in the day was positively associated with coercive food parenting practices (e.g., food restriction, pressure-to-eat) at dinner the same night. Further, prior day resource depletion was associated with greater pressure-to-eat the next day. Parents with lower chronic stress were found to engage in pressuring when experiencing higher depletion. Clinicians and public health professionals should be aware of the role the resource depletion can play in parent's use of specific food parenting practices and seek to provide parents with the support they need to manage the cognitive load they are experiencing.

Treatment of Binge-Eating Disorder Across the Lifespan: An Updated Review of the Literature and Considerations for Future Research. Curr Obes Rep 2024:10.1007/s13679-024-00553-4. [PMID: 38363468 DOI: 10.1007/s13679-024-00553-4] [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] [Accepted: 02/08/2024] [Indexed: 02/17/2024]
Abstract
PURPOSE OF REVIEW The present review describes the recent literature on treatment for binge-eating disorder (BED) in adults and youth, with a particular focus on research gaps, emerging treatments, and future research directions. RECENT FINDINGS Evidence supports the efficacy of several treatment modalities in adults, including self-help treatment, clinician-led psychotherapy, and pharmacotherapy; the largest effect sizes have been found for psychotherapies, most of which were cognitive-behavioral in orientation. Adapted psychotherapies for youth also show promise but lack a robust body of evidence. Predictors, moderators, and mediators of treatment outcome remain poorly understood; individuals with BED continue to experience significant barriers to treatment; and research is needed to address suboptimal treatment response. Recent work has highlighted the potential of adaptive interventions and investigation of novel mechanisms to address these gaps. Research on BED treatment continues to grow, though critical questions must be answered to improve treatment efficacy across the lifespan.

Associations among parents' internalized weight bias, negative child-focused body talk, and feeding behaviors. Eat Behav 2024; 52:101848. [PMID: 38308903 PMCID: PMC10922654 DOI: 10.1016/j.eatbeh.2024.101848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 01/23/2024] [Accepted: 01/24/2024] [Indexed: 02/05/2024]
Abstract
OBJECTIVE Parents' negative body talk about children (negative weight/shape comments) and internalized weight bias (application of negative weight-based stereotypes to oneself) are associated with children's maladaptive eating behaviors, but mechanisms are poorly understood. Conceptually, parental behaviors and attitudes may translate to implicit and explicit concerns about their child's weight and influence parents' feeding practices. These associations are underexplored in the literature. METHOD 242 parents (59.4% mothers) completed a one-time assessment that included measures of internalized weight bias, negative body talk, and feeding practices. Parents also completed assessments about one of their children, of any weight status (age range 5-15 years; 40% daughters). RESULTS Parents' internalized weight bias was positively associated with concern about their child's weight and restriction of their child's diet. Parents' negative body talk towards their child was positively associated with concern about their child's weight and shape, restriction of their child's diet, and monitoring of their child's diet. Relative to internalized weight-bias, negative body talk had a stronger correlation with parents' concern about child weight and monitoring of child's diet. Correlations did not vary by child gender or weight category. DISCUSSION Parents' internalized weight bias and negative body talk about their child were associated with their feeding practices across child gender and weight categories, with correlations in the small to medium range. Thus, children of all genders and weights may be vulnerable to enacted weight bias. Future studies should examine whether addressing parents' internalized weight bias and communication in family-focused interventions improves feeding practices and child well-being.

State-level working memory and dysregulated eating in children and adolescents: An exploratory ecological momentary assessment study. Int J Eat Disord 2024; 57:93-103. [PMID: 37888341 PMCID: PMC10872824 DOI: 10.1002/eat.24087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 10/17/2023] [Accepted: 10/18/2023] [Indexed: 10/28/2023]
Abstract
BACKGROUND Children with loss of control (LOC) eating and overweight/obesity have relative deficiencies in trait-level working memory (WM), which may limit adaptive responding to intra- and extra-personal cues related to eating. Understanding of how WM performance relates to eating behavior in real-time is currently limited. METHODS We studied 32 youth (ages 10-17 years) with LOC eating and overweight/obesity (LOC-OW; n = 9), overweight/obesity only (OW; n = 16), and non-overweight status (NW; n = 7). Youth completed spatial and numerical WM tasks requiring varying degrees of cognitive effort and reported on their eating behavior daily for 14 days via smartphone-based ecological momentary assessment. Linear mixed effects models estimated group-level differences in WM performance, as well as associations between contemporaneously completed measures of WM and dysregulated eating. RESULTS LOC-OW were less accurate on numerical WM tasks compared to OW and NW (ps < .01); groups did not differ on spatial task accuracy (p = .41). Adjusting for between-subject effects (reflecting differences between individuals in their mean WM performance and its association with eating behavior), within-subject effects (reflecting variations in moment-to-moment associations) revealed that more accurate responding on the less demanding numerical WM task, compared to one's own average, was associated with greater overeating severity across the full sample (p = .013). There were no associations between WM performance and LOC eating severity (ps > .05). CONCLUSIONS Youth with LOC eating and overweight/obesity demonstrated difficulties mentally retaining and manipulating numerical information in daily life, replicating prior laboratory-based research. Overeating may be related to improved WM, regardless of LOC status, but temporality and causality should be further explored. PUBLIC SIGNIFICANCE STATEMENT Our findings suggest that youth with loss of control eating and overweight/obesity may experience difficulties mentally retaining and manipulating numerical information in daily life relative to their peers with overweight/obesity and normal-weight status, which may contribute to the maintenance of dysregulated eating and/or elevated body weight. However, it is unclear whether these individual differences are related to eating behavior on a moment-to-moment basis.

Leveraging seasonality and timing to optimize pediatric weight management interventions: Novel directions for future research. Obes Sci Pract 2023; 9:688-695. [PMID: 38090686 PMCID: PMC10712410 DOI: 10.1002/osp4.694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 06/08/2023] [Accepted: 06/26/2023] [Indexed: 02/01/2024] Open
Abstract
National estimates suggest that more than 35% of American children, ages 2-19 years, are overweight or obese, which increases their risk for weight-related comorbidities including diabetes, cancer, cardiovascular disease risk factors, depression, and anxiety. While obesity prevention is most cost-effective, for youth with existing obesity, the United States Preventive Services Task Force recommends ≥26 h of comprehensive lifestyle intervention over 6-12 months. This include standard behavioral therapy, dietary counseling, and an emphasis on physical activity. Although such programs are effective in reducing weight status, there are many barriers to completing these programs. A novel consideration for both the prevention and treatment of childhood obesity is the recognition that the timing of intervention, both duration and time of the year, can impact family engagement and intervention effectiveness. This paper discusses the potential of targeting high-risk periods for weight gain and offering brief behavioral intervention, in hopes of inspiring research on novel approaches to the prevention and treatment of childhood obesity.

Multi-electrolyte disturbance and supplementation in severely malnourished hospitalized adolescents with restrictive eating disorders. J Eat Disord 2023; 11:202. [PMID: 37968751 PMCID: PMC10647075 DOI: 10.1186/s40337-023-00919-4] [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: 06/07/2023] [Accepted: 10/27/2023] [Indexed: 11/17/2023] Open
Abstract
BACKGROUND This study describes the prevalence of hypophosphatemia, hypokalemia, and/or hypomagnesemia and resulting electrolyte supplementation during refeeding in severely malnourished youths hospitalized for restrictive eating disorders. METHODS Hospitalized patients between 11-26y (N = 81) at < 75% treatment goal weight (TGW) were assessed through retrospective chart review. Outcomes were compared between participants < 70% TGW and those 70-75% TGW. Nutritional rehabilitation started at 1750 kcals/day and advanced by 500 kcal every other day until target intake was achieved. Associations between %TGW on admission; hypophosphatemia, hypokalemia, and/or hypomagnesemia; and electrolyte supplementation were examined. RESULTS Of the 24 (29.6%) participants with hypophosphatemia, hypokalemia, and/or hypomagnesemia, 7 (8.6%) received supplementation; the remainder corrected without supplementation. Participants < 70% TGW did not differ from those 70-75% TGW on rates of these conditions or need for supplementation. CONCLUSIONS Hospital-based nutritional rehabilitation did not confer increased rates of hypophosphatemia, hypokalemia, and/or hypomagnesemia or need for electrolyte supplementation in patients < 70% TGW compared to those 70-75% TGW. While additional research is needed to establish clinical practice guidelines on electrolyte management in this population, our findings suggest that nutritional rehabilitation may be reasonably undertaken without prophylactic electrolyte supplementation, even in patients < 70% TGW.

Adapting family-based treatment for adolescent anorexia nervosa delivered in the home: A novel approach for improving access to care and generalizability of skill acquisition. J Eat Disord 2023; 11:130. [PMID: 37543601 PMCID: PMC10403819 DOI: 10.1186/s40337-023-00850-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 07/26/2023] [Indexed: 08/07/2023] Open
Abstract
BACKGROUND Anorexia nervosa (AN) is a serious mental illness associated with high rates of morbidity and mortality. Family-based treatment (FBT) is a well-established treatment for adolescent AN, yet it is underutilized in community settings and is unavailable to many families, particularly those from lower income and racial and ethnic minority backgrounds. Furthermore, some families do not respond optimally to FBT, possibly because of challenges translating skills acquired in office-based treatment settings to naturalistic settings. Home-based treatment could reduce barriers to access and enhance generalization of newly learned treatment skills. Home-based models demonstrate initial feasibility, acceptability, and efficacy for adolescent AN, however, FBT principles have yet to be applied as a stand-alone intervention in a home-based level of care. This paper describes the rationale for and process of adapting FBT principles/interventions to improve fit within a home-based model delivered in the context of community mental health, and discusses potential strengths and opportunities associated with this approach. RESULTS Adaptations were made through consultation with collaborating community agencies and were guided by the complex interventions framework. The primary modifications included: (1) altered dose; (2) multiple family meals; (3) additional support for meal preparation and supervision; (4) clinician attendance at medical appointments; (5) cultural adaptation; and (6) introduction of distress tolerance and emotion regulation skills. CONCLUSIONS Implementing FBT in the home may present one promising and novel approach to enhance engagement and treatment outcomes for adolescents with restrictive eating disorders, particularly those who are underserved, but evaluation of efficacy/effectiveness is needed.

Eating disorders in weight-related therapy (EDIT): Protocol for a systematic review with individual participant data meta-analysis of eating disorder risk in behavioural weight management. PLoS One 2023; 18:e0282401.

Abstract
The Eating Disorders In weight-related Therapy (EDIT) Collaboration brings together data from randomised controlled trials of behavioural weight management interventions to identify individual participant risk factors and intervention strategies that contribute to eating disorder risk. We present a protocol for a systematic review and individual participant data (IPD) meta-analysis which aims to identify participants at risk of developing eating disorders, or related symptoms, during or after weight management interventions conducted in adolescents or adults with overweight or obesity. We systematically searched four databases up to March 2022 and clinical trials registries to May 2022 to identify randomised controlled trials of weight management interventions conducted in adolescents or adults with overweight or obesity that measured eating disorder risk at pre- and post-intervention or follow-up. Authors from eligible trials have been invited to share their deidentified IPD. Two IPD meta-analyses will be conducted. The first IPD meta-analysis aims to examine participant level factors associated with a change in eating disorder scores during and following a weight management intervention. To do this we will examine baseline variables that predict change in eating disorder risk within intervention arms. The second IPD meta-analysis aims to assess whether there are participant level factors that predict whether participation in an intervention is more or less likely than no intervention to lead to a change in eating disorder risk. To do this, we will examine if there are differences in predictors of eating disorder risk between intervention and no-treatment control arms. The primary outcome will be a standardised mean difference in global eating disorder score from baseline to immediately post-intervention and at 6- and 12- months follow-up. Identifying participant level risk factors predicting eating disorder risk will inform screening and monitoring protocols to allow early identification and intervention for those at risk.

Abstract
Eating disorders (EDs) present high costs to the individual and society, and need for services far surpasses their availability. Caregivers are often on the "front lines" of managing their child's illness yet may have very little support to sustain them in this role. It is well-established that caregiver burden related to EDs is high, although most research has focused on caregivers of adult patients. Wilksch describes the need for additional attention to caregivers of children and adolescents with EDs, given the elevated psychological, interpersonal, and financial burden incurred on this segment of the population. In this commentary, we describe three major gaps in service delivery and research that may exacerbate caregiver stress: (1) limited exploration of "nontraditional" delivery modalities that could enhance access to care; (2) lack of research into viability of caregiver peer coaching/support models including respite resources; and (3) scarcity of accessible ED training for healthcare providers (particularly physicians) which increases length to receipt of competent care as families search for well-trained providers and/or languish on waitlists. We propose prioritizing additional research in these areas to help alleviate caregiver burden associated with pediatric EDs, and facilitate delivery of prompt, comprehensive, and competent care to support optimal prognosis.

Accelerometer-Based Physical Activity and Shape and Weight Concerns Among Youth With Overweight and Obesity: A Pilot Exploratory Ecological Momentary Assessment Study. Child Obes 2023.

Abstract
Background: A bidirectional association between shape and weight concerns (SWC) and physical activity (PA) has been previously documented. This relationship may be particularly salient among youth with overweight/obesity, given that social marginalization of larger bodies has been associated with elevated SWC and barriers to PA. This pilot study explores reciprocal relationships between momentary SWC and accelerometer-assessed PA behavior. Methods: Youth with overweight/obesity (N = 17) participated in a 14-day ecological momentary assessment protocol, during which they were prompted to respond to questions about SWC several times per day. They also continuously wore Actiwatch 2 accelerometers to capture light and moderate-to-vigorous PA behavior. Results: Hierarchical linear modeling revealed a unidirectional association between SWC and PA, whereby after engaging in a higher duration of PA, participants reported lower SWC. SWC did not predict subsequent PA. Conclusion: The findings support a negative temporal relationship between PA and SWC. While further work is needed to replicate and extend these preliminary findings, they may suggest that PA acutely benefits SWC among youth with overweight and obesity.

Cognitive-behavioral therapy and exercise training in adolescent females with elevated depression symptoms and at-risk for type 2 diabetes: Protocol for a randomized controlled trial. Contemp Clin Trials 2023; 128:107150.

Abstract
BACKGROUND Adolescent-onset type 2 diabetes (T2D) is a major public health concern of growing proportions. Prevention, therefore, is critical. Unfortunately, standard-of-care treatment for T2D prevention (e.g., exercise training) show insufficient effectiveness and do not address key modifiable barriers (e.g., depression symptoms) to exercise engagement. Depression symptoms are associated with both poorer physical fitness and greater insulin resistance, the key risk factor in adolescent-onset T2D. Thus, a targeted prevention approach that addresses depression symptoms in combination with exercise training may offer a novel approach to mitigating T2D risk. METHODS This manuscript describes the design and study protocol for a multi-site, four-arm randomized controlled trial comparing the efficacy of group cognitive-behavioral therapy, group exercise training, and their combinations for the targeted prevention of worsening insulin resistance in N = 300 adolescent females at-risk for T2D with BMI ≥85th percentile and elevated depression symptoms. All four intervention arms will run in parallel and meet weekly for 1 h per week for 6-week to 6-week segments (12 weeks total). Outcomes are assessed at baseline, 6-week mid-treatment, 12-week follow-up, and 1-year follow-up. RESULTS The primary outcome is insulin resistance. Key secondary outcomes include insulin sensitivity, cardiorespiratory fitness, physical activity, depression symptoms, and body measurements. CONCLUSION Study findings will guide the ideal sequencing of two brief T2D prevention interventions for ameliorating the course of insulin resistance and lessening T2D risk in vulnerable adolescents. These interventions will likely be cost-effective and scalable for dissemination, having the potential for significant public health impact on communities at risk for T2D.

Abstract
Importance Lifestyle change is central to diabetes risk reduction in youth with overweight or obesity. Feeling susceptible to a health threat can be motivational in adults. Objective To evaluate associations between diabetes risk perception and/or awareness and health behaviors in youth. Design, Setting, and Participants This cross-sectional study analyzed data from the US National Health and Nutrition Examination Survey 2011 to 2018. Participants included youths aged 12 to 17 years with body mass index (BMI) in the 85th percentile or higher without known diabetes. Analyses were conducted from February 2022 to February 2023. Main Outcomes and Measures Outcomes included physical activity, screen time, and attempted weight loss. Confounders included age, sex, race and ethnicity, and objective diabetes risk (BMI, hemoglobin A1c [HbA1c]). Exposures Independent variables included diabetes risk perception (feeling at risk) and awareness (told by clinician), as well as potential barriers (eg, food insecurity, household size, insurance). Results The sample included 1341 individuals representing 8 716 794 US youths aged 12 to 17 years with BMI in the 85th percentile or higher for age and sex. The mean age was 15.0 years (95% CI, 14.9-15.2 years) and mean BMI z score was 1.76 (95% CI 1.73-1.79). Elevated HbA1c was present in 8.6% (HbA1c 5.7%-6.4%: 8.3% [95% CI, 6.5%-10.5%]; HbA1c ≥6.5%: 0.3% [95% CI, 0.1%-0.7%]). Nearly one-third of youth with elevated HbA1c reported risk perception (30.1% [95% CI, 23.1%-38.1%), while one-quarter (26.5% [95% CI, 20.0%-34.2%]) had risk awareness. Risk perception was associated with increased TV watching (β = 0.3 hours per day [95% CI, 0.2-0.5 hours per day]) and approximately 1 less day per week with at least 60 minutes of physical activity (β = -1.2 [95% CI, -2.0 to -0.4) but not with nutrition or weight loss attempts. Awareness was not associated with health behaviors. Potential barriers had mixed associations: larger households (≥5 members vs 1-2) reported lower consumption of non-home-prepared meals (OR 0.4 [95% CI, 0.2-0.7]) and lower screen time (β = -1.1 hours per day [95% CI, -2.0 to -0.3 hours per day), while public insurance (vs private) was associated with approximately 20 fewer minutes per day of physical activity (β = -20.7 minutes per day [95% CI, 35.5 to -5.8 minutes per day]). Conclusions and Relevance In this cross-sectional study including a US-representative sample of adolescents with overweight or obesity, diabetes risk perception and awareness were not associated with greater engagement in risk-reducing behaviors in youth. These findings suggest the need to address barriers to engagement in lifestyle change, including economic disadvantage.

When eating disorder attitudes and cognitions persist after weight restoration: An exploratory examination of non-cognitive responders to family-based treatment for adolescent anorexia nervosa. EUROPEAN EATING DISORDERS REVIEW 2023; 31:425-432.

Abstract
OBJECTIVE Family-based treatment (FBT) is a well-established intervention for adolescent anorexia nervosa (AN). Although FBT is efficacious in promoting weight gain and improvements in psychological symptoms, for some adolescents, cognitive/attitudinal recovery lags behind weight gain. This study conducted an exploratory post hoc analysis of outcomes of adolescents who achieved weight gain by the end of FBT but continued to experience elevated psychological symptoms post-treatment. METHODS Data were drawn from two randomised controlled trials (RCTs) testing two forms of FBT (conjoint/whole family and parent-focussed). Descriptive statistics and generalised estimating equations were used to examine differences in treatment outcomes between non-cognitive responders (NCRs) (those who regained weight but continued to experience psychological symptoms) and full responders (FRs) (those who achieved both weight and cognitive restoration by the end of treatment) (n = 80; 83.7% female, Agemean [SD] = 14.66 [1.73]). RESULTS By 12 months post-treatment, there were no differences in weight between NCRs and FRs. However, NCRs had a slower trajectory of weight gain than FRs and continued to have elevated levels of psychological symptoms throughout the follow-up period. CONCLUSIONS A subset of adolescents appear to continue to experience clinically significant levels of eating pathology up to 12 months after FBT even when weight restoration is achieved.

[PMID: 36627731 PMCID: PMC10806484 DOI: 10.1002/oby.23628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 09/29/2022] [Accepted: 10/03/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVE Loss-of-control (LOC) eating is common in adults undergoing bariatric surgery. Agreement between real-time and retrospective assessment methods is unclear. METHODS Adults with severe obesity reported on LOC eating over the preceding 28 days via Eating Disorder Examination-Questionnaire (EDE-Q) items and in near real time over 10 days via ecological momentary assessment (EMA; involving daily repeated surveys delivered via smartphone in the natural environment), with both assessment forms completed before surgery and at 3, 6, and 12 months after surgery. Wilcoxon signed rank tests and generalized linear mixed models were used to compare participants' EDE-Q and EMA reports of subjectively and objectively large LOC episodes across time points. RESULTS Participants reported subjectively large LOC episodes more frequently via EMA than EDE-Q across time points, although differences did not reach statistical significance (all p > 0.05). Conversely, objectively large LOC episodes were more frequently reported via EDE-Q than EMA, with differences reaching significance at 6 months post surgery only (p = 0.03). CONCLUSIONS Agreement between real-time and retrospective assessments of LOC eating varied by episode size and time elapsed in the year following surgery. These findings should be considered when designing assessment batteries for bariatric surgery-seeking adults and when extrapolating research findings across studies with diverging methods of real-time versus retrospective self-report assessment of LOC eating in adults undergoing bariatric surgery.

The moderating role of sleep duration on momentary relations between negative affect and loss-of-control eating in children and adolescents. EUROPEAN EATING DISORDERS REVIEW 2022; 30:815-822. [PMID: 35474597 PMCID: PMC10860376 DOI: 10.1002/erv.2908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 03/01/2022] [Accepted: 04/08/2022] [Indexed: 11/08/2022]
Abstract
OBJECTIVE Loss-of-control (LOC) eating is associated with eating disorders and obesity, and thus it is imperative to understand its momentary risk factors in order to improve intervention efforts. Negative affect has been proposed as a momentary risk factor for LOC eating, but the evidence for its effects in children and adolescents is mixed. Short sleep duration (which is very common in youth), may be one variable that moderates the relation between negative affect and subsequent LOC eating. As such, we aimed to examine the moderating role of within-person sleep duration on the momentary relations between negative affect and subsequent LOC eating. METHOD We recruited children (N = 30) with overweight/obesity ages 8-14, who completed a 2-week ecological momentary assessment protocol assessing negative affect and LOC eating several times per day, while also wearing a sleep actigraphy device and completing sleep diaries. RESULTS Consistent with hypotheses, within-person sleep duration moderated the next-day momentary relation between within-person negative affect and LOC eating, such that shorter sleep duration strengthened the positive relation between negative affect and loss-of-control eating. CONCLUSIONS Results suggest that, in children and adolescents, fluctuations in sleep duration may influence susceptibility to losing control over eating after experiencing negative affect. Future research should further investigate other metrics of sleep disturbance as they relate to emotion regulation and LOC eating. Such research will set the stage for augmenting paediatric interventions to better target maintenance factors for LOC eating.

Implementation and outcomes of home-based treatments for adolescents with anorexia nervosa: Study protocol for a pilot effectiveness-implementation trial. Int J Eat Disord 2022; 55:1627-1634. [PMID: 36324297 PMCID: PMC10018372 DOI: 10.1002/eat.23796] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 07/28/2022] [Accepted: 07/28/2022] [Indexed: 11/08/2022]
Abstract
OBJECTIVE Although family-based treatment (FBT) is considered a first-line treatment for adolescent anorexia nervosa (AN), it is underutilized in community settings and is unavailable to many families for a multitude of practical reasons (e.g., costs of treatment, transportation constraints). Adapting FBT interventions for delivery in home-based and community-based settings may reduce pragmatic barriers to treatment uptake and engagement. METHODS This pilot effectiveness-implementation trial will assess outcomes, implementation, and mechanisms of FBT adapted for the home setting (FBT-HB), delivered in the context of community-based behavioral health agencies. Adolescents with AN-spectrum disorders (n = 50) and their caregivers will be randomly assigned to either FBT-HB or home-based treatment as usual (TAU; integrated family therapy approach). Caregivers and adolescents will provide data on weight, eating, and putative treatment mechanisms, including caregiver self-efficacy and adolescent eating-related and weight-related distress. Implementation constructs of feasibility, acceptability, and appropriateness will be measured among providers and participating families. HYPOTHESES We expect that FBT-HB will be feasible, acceptable, and appropriate, and will outperform TAU in terms of improvements in adolescent weight and eating-related psychopathology. We further expect that caregiver self-efficacy and adolescent eating-related and weight-related distress, but not general distress, will show greater improvements in FBT-HB relative to TAU and will be associated with better adolescent weight and eating outcomes in FBT-HB. POTENTIAL IMPLICATIONS The proposed study has clear potential to advance scientific and clinical understanding of the real-world effectiveness of FBT for AN, including whether adapting it for the home setting improves its accessibility and effects on treatment outcome.

Psychosocial predictors of problematic eating in young adults who underwent adolescent bariatric surgery. Obes Sci Pract 2022; 8:545-555. [PMID: 36238228 PMCID: PMC9535670 DOI: 10.1002/osp4.590] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 12/18/2021] [Accepted: 12/23/2021] [Indexed: 11/08/2022] Open
Abstract
Introduction This study examined problematic eating and eating-related psychopathology among young adults who underwent adolescent bariatric surgery including concurrent and prospective associations with psychosocial factors and weight change. Methods VIEW point is a 6-year follow-up study within a prospective observational study series observing adolescents with severe obesity who had bariatric surgery (n = 139) or who presented to nonsurgical lifestyle modification programs (n = 83). Participants completed height/weight measurements, questionnaires, and diagnostic interviews. Regression analyses compared problematic eating across groups and examined Year 6 correlates (i.e., psychosocial factors and weight change) and baseline predictors (i.e., psychosocial factors) of eating-related psychopathology. Results Compared to the nonsurgical group, the surgical group reported lower eating-related psychopathology, objective binge eating, and grazing at Year 6. While chewing/spitting out and vomiting for weight/shape-related reasons were very infrequent for the surgical group, self-induced vomiting for other reasons (e.g., avoid plugging) was more common. For the surgical group, lower self-worth, greater internalizing symptoms, and higher weight-related teasing in adolescence predicted increased eating-related psychopathology in young adulthood. Year 6 eating-related psychopathology was concurrently associated with lower percent weight loss for the surgical group and greater percent weight gain for the nonsurgical group. Conclusion Undergoing adolescent bariatric surgery appears to afford benefit for problematic eating and eating-related psychopathology. Current findings suggest that the clinical intervention related to problematic eating and associated psychosocial concerns may be needed for young adults with obesity, regardless of surgical status.

The Role of Affective Instability in Loss of Control Eating in Youth with Overweight/Obesity Across Development: Findings from Two EMA Studies. Res Child Adolesc Psychopathol 2022; 50:945-957. [PMID: 35039971 PMCID: PMC10375484 DOI: 10.1007/s10802-021-00886-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/16/2021] [Indexed: 11/26/2022]
Abstract
Affective instability is common during adolescence, but at high levels it is associated with a variety of internalizing and externalizing disorders, including eating disorders. Although most models focus on affective intensity as a mechanism for explaining eating disorders in adults, affective instability may be more developmentally relevant at predicting eating behaviors in youth. Using ecological momentary assessment, this manuscript explored the association between loss of control over eating (LOC), a key component of dysregulated eating in youth, and affective instability in youth with overweight/obesity in two separate studies, one with youth in middle childhood and early adolescence (Study 1: ages eight to 13) and one in youth in early through middle adolescence (Study 2: ages 12-17). Overall, there was no association between affective instability and LOC in Study 1, but in Study 2, age moderated the association between positive affective instability and LOC, such that greater between-person positive affective instability (i.e., relative to peers) was associated with lower average LOC for youth earlier in adolescence and higher average LOC for those later in adolescence. Negative affective instability was also associated with LOC in Study 2, such that on days when youth reported less within-person negative affective instability (i.e., relative to their own average), they also reported greater average LOC. Findings across the two studies indicate that the association between affective instability and LOC may not emerge until adolescence, and when it does, both positive and negative affective instability may be important to consider.

Gender differences in the relation between interpersonal stress and momentary shape and weight concerns in youth with overweight/obesity. Body Image 2022; 40:249-255. [PMID: 35074653 PMCID: PMC8891090 DOI: 10.1016/j.bodyim.2022.01.006] [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: 08/29/2021] [Revised: 01/17/2022] [Accepted: 01/17/2022] [Indexed: 10/19/2022]
Abstract
The purpose of this study was to examine relations between interpersonal stress and momentary shape and weight concerns among pre-adolescent and early adolescent boys and girls with overweight/obesity, using ecological momentary assessment (EMA). We also aimed to determine whether interpersonal stress was differentially related to shape/weight concerns in boys versus girls. Forty youth, ages 8-14 years (53% female), with overweight or obesity reported their state-level shape/weight concerns and negative affect and their recent interpersonal stress (i.e., stress experienced since the last EMA assessment) multiple times a day, for two weeks. Results indicated that interpersonal stress predicted shape/weight concerns in girls but was not related to shape/weight concerns in boys. At the between-person level, higher overall feelings of loneliness and social rejection and a higher overall desire for more friends predicted higher average levels of shape/weight concerns. At the within-person level, higher momentary ratings of loneliness, social rejection, and desire for more friends predicted lower shape/weight concerns. These data suggest that the tendency to experience interpersonal stress may be more detrimental to body satisfaction for girls with overweight/obesity than for boys with overweight/obesity. Interventions that focus on reducing interpersonal stress may be effective in ameliorating shape/weight concerns in girls with overweight/obesity.

Dynamic associations between anxiety, stress, physical activity, and eating regulation over the course of a behavioral weight loss intervention. Appetite 2022; 168:105706. [PMID: 34560159 PMCID: PMC8671217 DOI: 10.1016/j.appet.2021.105706] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 07/23/2021] [Accepted: 09/20/2021] [Indexed: 01/03/2023]
Abstract
Negative emotional experiences are associated with dysregulated eating behaviors that impede weight management. While weight loss interventions promote physical activity and self-regulation of eating, no studies have examined how physical activity may directly influence eating by attenuating associations between negative emotions and eating. OBJECTIVE The current study examined how momentary negative emotions (stress and anxiety), moderate-to-vigorous intensity physical activity (MVPA), and their interactions predict eating dysregulation (i.e., intensity of eating temptations, inability to resist eating tempting foods, overeating), as well as how these associations change during a weight loss intervention. METHODS Women with overweight/obesity (N = 55) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after a three-month internet-based weight loss program. RESULTS Three-way interactions emerged predicting overeating and eating tempting foods. When women experienced higher than usual levels of momentary anxiety or stress at end-of-treatment, they were less likely to subsequently overeat or eat tempting foods when they had recently engaged in more MVPA (relative to their usual level). No significant associations were found for ratings of temptation intensity. CONCLUSIONS Findings suggest MVPA may exert direct effects on eating regulation. Specifically, MVPA appears to increasingly buffer the effect of negative emotional states on dysregulated eating behavior over the course of a weight loss intervention. Future work is needed to develop ways of communicating to patients how activity can have both indirect and direct effects on body weight, and examine whether such knowledge improves outcomes.

Typology of eating episodes in children and adolescents with overweight/obesity. Eat Behav 2022; 44:101596.

Abstract
BACKGROUND Research suggests that youth with overweight/obesity can be subtyped according to disinhibited eating tendencies. No research has attempted to subtype classes of eating episodes along sensational, psychological, and hedonic dimensions. METHODS Youth (N = 39; 55% female) aged 8-14 y with overweight/obesity completed a 2-week ecological momentary assessment protocol in which they reported on all eating episodes and their sensational, environmental, affective, and interpersonal contexts. Latent profile analysis (LPA) was used to classify episodes based on loss of control (LOC) while eating, self-reported overeating, food palatability, hunger, and cravings. Classes were compared on affective, interpersonal, appearance-related, and environmental correlates using Wald chi-square tests. RESULTS LPA identified three classes of eating episodes involving high levels of LOC/self-reported overeating ("binge-like" class), low levels of hunger ("eating-in-the-absence-of-hunger" class), and high hunger and cravings ("appetitive eating" class). Binge-like eating was associated with the highest levels of body dissatisfaction, interpersonal distress, and positive affect, and was most likely to occur in the after-school hours. CONCLUSIONS Binge-like eating tends to occur in a psychological context relative to other types of eating episodes in youth with overweight/obesity. Future research should explore whether certain classes of eating episodes are associated with distinct weight trajectories over time.

Momentary affective response to bouts of moderate-to-vigorous physical activity predicts changes in physical activity and sedentary behavior during behavioral weight loss. PSYCHOLOGY OF SPORT AND EXERCISE 2021; 57:102056.

Abstract
BACKGROUND Affective responses are posited to be key predictors of the uptake and maintenance of health behaviors. However, few studies have examined how individuals' affective response to physical activity, as well as the degree to which their affect response changes, may predict changes in physical activity and sedentary time during behavioral weight loss treatment. PURPOSE The current study examined how baseline momentary affective response (i.e., stress and anxiety) to moderate-to-vigorous physical activity (MVPA) and the degree of pre--post intervention change in this response predicted change in daily sedentary, light, and MVPA time during a three-month internet-based weight loss program. METHODS Women with overweight/obesity (final N=37) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after the intervention. RESULTS Women who had more reinforcing responses to MVPA (i.e., greater reductions in anxiety and stress response following MVPA bouts) at baseline had greater increases in overall MVPA at the end of the intervention. Those who had greater anxiety reductions after MVPA bouts at baseline also evidenced less sedentary time at the end of the intervention. Changes in affective responses across the intervention were not related to changes in physical activity levels. CONCLUSIONS Findings suggest initial levels of affective reinforcement from MVPA bouts predict future change in MVPA and sedentary time during behavioral weight loss. Future work is needed to examine the utility of more precisely targeting affective responses to physical activity to optimize intervention approaches.

Abstract
OBJECTIVE In adults, pain is prospectively associated with overweight/obesity and concurrently associated with dysregulated eating, with evidence for stronger associations in women than men. This study aimed to evaluate whether similar associations among pain response, BMI, and loss of control (LOC) eating are also evident in adolescent girls. METHOD Girls (n = 202) completed the cold pressor test (CPT) at age 10, and BMI and LOC eating were assessed annually from ages 10-16 years. Generalized linear models were used to test associations between pain tolerance (total immersion time) and threshold (latency to highest pain rating), and changes in BMI and LOC eating. RESULTS Lower pain tolerance and threshold at age 10 were associated with increases in LOC eating from age 10 to 16 (tolerance: B < -.01, SE < .01, p = .005; threshold: B = -.03, SE = .01, p = .0118). No significant associations were observed between pain tolerance/threshold and increasing BMI. DISCUSSION Pain responsivity in childhood is associated with increases in dysregulated eating from childhood to adolescence. These findings provide support for the early development of an interface between pain and eating behaviors.

Abstract
OBJECTIVES The aim of this study was to assess associations between loss of control (LOC) eating and health outcomes among adolescents undergoing metabolic and bariatric surgery. METHODS A total of 234 adolescents were studied before and up to 6 years after surgery in a prospective, observational cohort design. Adolescents provided self-reports of LOC eating, pain severity, sleep quality, polycystic ovary syndrome, gastroesophageal reflux disease, and medication usage and objective measures of fasting glucose, serum insulin, glycohemoglobin A1c , cholesterol, triglycerides, and blood pressure. χ2 tests, Wilcoxon rank sums, and generalized linear mixed models were used to assess concurrent and prospective associations between LOC eating and health indicators. RESULTS LOC eating presented in 32.5% of adolescents before surgery and was positively associated with sleep disturbances and psychiatric medication usage. After surgery, LOC eating presented in 7.9% to 14.6% of participants and was correlated with improved low- and high-density lipoprotein cholesterol levels and greater back pain. LOC eating was inversely associated with low-density lipoprotein cholesterol at the next consecutive time point. CONCLUSIONS LOC eating was unexpectedly associated with improved low- and high-density lipoprotein cholesterol in adolescents undergoing metabolic and bariatric surgery. Deleterious effects of LOC eating on obesity-related health conditions, aside from back pain, were not detected. Metabolic and other weight-independent health benefits of surgery may persist postoperatively despite LOC eating and associated weight regain.

Abstract
BACKGROUND Gastrointestinal symptoms (GIS) are common after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). However, little is known about frequencies of GIS and their co-occurrence with risky eating behaviors. OBJECTIVES Compare RYGB and SG on GIS and risky eating behaviors, and test associations between GIS and behaviors. SETTING Two university hospitals in Northeastern United States. METHODS RYGB (n = 18) and SG (n = 53) patients completed smartphone-based ecological momentary assessment of GIS and risky eating behaviors at 4 semi-random times daily for 10 days preoperatively and at 3, 6, and 12 months postoperatively. Study objectives were evaluated using generalized linear mixed-effects models. RESULTS All available data from each assessment were included in the analysis: participant attrition was 18%, 30%, and 38% at 3, 6, and 12 months. All GIS were reduced at 12 months postoperative. Bloating decreased consistently whereas cramping, dehydration, and dumping first increased at 3 to 6 months then decreased to 12 months. Diarrhea, nausea, reflux, and vomiting decreased to 12 months for RYGB, but first increased at 3 to 6 months then decreased to 12 months for SG. Consumption of carbonated and sugar-sweetened beverages, fatty meats, and sweets decreased to 6 months then rebounded at 12 months. Eating past the first sign of fullness, drinking liquids with meals, not starting meals with protein, and fried foods consumption decreased to 6 months and then rebounded for RYGB only at 12 months. Alcohol consumption did not change. Sweets consumption and eating past the first sign of fullness were most consistently associated with GIS for both RYGB and SG patients. CONCLUSION GIS and risky eating behaviors improved postoperatively, although patterns of change were variable and occasionally differed between RYGB and SG. Pending replication, patients may benefit from intervention to limit risky behaviors that are tailored to their surgery type.

Momentary associations between positive affect dimensions and dysregulated eating during puberty in a diverse sample of youth with overweight/obesity. Int J Eat Disord 2020; 53:1667-1677.

Abstract
OBJECTIVE The link between dysregulated positive affect and binge-eating behavior in youth with obesity is poorly understood. In addition, it is unclear how putative associations differ across developmental periods of rapid biological and emotional change, such as puberty, and in racial and ethnic minority youth, who are more likely to be overweight but are underrepresented in the literature. METHOD This study used a 2-week ecological momentary assessment protocol to examine independent and interactive effects of positive affect intensity/instability, and pubertal stage on two components of binge-eating behavior, loss of control eating (LOCE), and overeating. RESULTS Participants were 38 youth with overweight/obesity (ages 8-14 years; 78% African American/Hispanic). Positive affect instability was calculated using probability of acute change (PAC), representing the likelihood of extreme affective changes, and mean squared successive difference (MSSD), representing the average change in affect over successive recordings. There were no main effects of positive affect intensity on LOCE or overeating, but positive affect instability was negatively associated with overeating severity using both MSSD (p = .005) and PAC metrics (p = .001). However, moderation analyses including interactions with pubertal status revealed more extreme changes in positive affect (i.e., higher PAC) were related to greater overeating (p = .001) and LOCE severity (p = .043) in mid-late pubertal youth but not in pre-early pubertal youth. DISCUSSION Pubertal status may influence the association between disruptions in positive affect and dysregulated eating in youth, and positive affect instability may be important to consider in order to understand the emotional correlates of binge eating in youth with overweight/obesity.

Abstract
Background: Research on the interplay between mothers' and children's eating behaviors is needed to better inform sensitive and tailored interventions for treatment-seeking children with overweight/obesity. The present study aimed to identify mothers' eating behavior phenotypes, investigating their associations with problematic eating behaviors of children undergoing weight loss treatment in two central hospitals. Methods: This is a cross-sectional study evaluating 136 mother-child dyads (Mothers: age 39.58 ± 5.40 years; Children: n = 75 female; age 10.13 ± 1.37 years). Mothers' eating behavior (restraint, emotional, and uncontrolled eating) and depression/anxiety, and children's problematic eating attitudes/behaviors were assessed. A cluster analysis (K-means) was performed using mothers' eating behavior dimensions. Multivariate Analysis of Covariance investigated differences between clusters on mothers' and children's sociodemographic, anthropometric, psychological, and eating-related variables. Results: Three clusters emerged: The Disordered Eating group (n = 39) of mothers with the highest scores on emotional eating and uncontrolled eating dimensions, the Restraint Eating group (n = 48), including mothers scoring high in cognitive restraint, and the Low Disordered Eating (n = 49) group where mothers scored low in all eating behavior dimensions. Children of mothers in the Disordered Eating cluster had significantly higher emotional overeating relative to children of mothers in the other two clusters. Conclusions: Distinctive eating behavior profiles of mothers, instead of the presence of single eating behaviors, seem to be associated with specific problematic eating behaviors of children undergoing weight loss treatment. Prospective studies are essential to determine whether these profiles can predict differential weight change trajectories in pediatric obesity treatment.

Abstract
OBJECTIVE Psychotropic medication use in youth with eating disorders (EDs) is poorly understood despite high co-occurrence of psychiatric disorders. This study examined characteristics associated with medication use in treatment-seeking youth with EDs. METHOD Youth up to age 18 reported on medication use when presenting to an academic medical center outpatient ED service in the United States. Data presented were collected between 1998-2015. RESULTS The sample (N = 604) was predominantly female (90.6%) with a mean age of 15.3 years (SD = 2.3). Approximately one-third (30%, n = 173) were taking psychotropic medications (40%, n = 70, were taking multiple medications). Antidepressant use was most common (26%, n = 152), followed by atypical antipsychotics (8%, n = 43). Adjusting for co-occurring psychiatric disorders, non-Hispanic Whites who had received prior treatment (psychotherapy, hospitalization) were significantly more likely to be using medication. Longer illness duration and prior treatment were associated with greater antidepressant use. For atypical antipsychotics, prior hospitalization was associated with greater use. CONCLUSIONS Findings confirm moderate psychotropic medication use among young patients with EDs despite a lack of clarity regarding optimally effective pharmacologic interventions in this population. Pharmacological trials examining the efficacy of medications for young patients with EDs are warranted to inform future prescribing practice.

The interactive effects of parental self-efficacy and child eating styles in relation to naturalistically-assessed craving, overeating, and loss of control eating. Int J Eat Disord 2020; 53:1450-1459. [PMID: 32432827 PMCID: PMC7937334 DOI: 10.1002/eat.23296] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 04/05/2020] [Accepted: 04/29/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVE Parental factors have been linked to weight-related outcomes in children, though less is known regarding the role of parental self-efficacy (PSE) for promoting healthy dietary behaviors (HDBs). This study examined associations between PSE for promoting HDBs and child reports of craving, overeating, and loss of control eating in daily life. The interactive effects of PSE and child eating style (emotional eating, external eating, and restraint) were also explored. METHOD Thirty-eight youth (ages 8-14; 55.3% female) with overweight/obesity and their parents completed the Dutch Eating Behavior Questionnaire for Children (DEBQ-C) and Parental Self-Efficacy for Healthy Dietary and Physical Activity Behaviors Scale, respectively. Youth completed ecological momentary assessment (EMA) to report craving, overeating, and loss of control eating. RESULTS Generalized estimating equations indicated no consistent main effects of PSE on EMA outcomes, but PSE interacted with DEBQ-C child eating styles to predict each EMA outcome. Among children of parents with lower PSE, (a) higher emotional eating was associated with greater overeating and loss of control eating; (b) higher external eating was associated with greater craving; and (c) higher restraint was associated with greater loss of control eating and craving. Conversely, these associations were attenuated among children of parents with higher PSE. DISCUSSION Together findings suggest the interplay of child characteristics and PSE regarding children's eating behaviors warrants future investigation in the context of eating and weight disorders. In particular, further research is needed to examine the directionality of effects and mechanisms underlying these associations.

The Implicit Association of High-Fat Food and Shame Among Women Recovered From Eating Disorders. Front Psychol 2020; 11:1068. [PMID: 32581937 PMCID: PMC7283547 DOI: 10.3389/fpsyg.2020.01068] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 04/27/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Despite the growing literature about recovery from eating disorders (EDs), it is still unknown if women who report being recovered from EDs present with differing implicit attitudes about high-fat (vs. low-fat) food relative to women who report having a current ED and women who report never having had an ED. METHODS Female volunteers (N = 2,785) to the Project Implicit Mental Health (PIMH) website (https://implicit.harvard.edu/) were divided into three ED groups: current ED (n = 335), prior ED (n = 393), and healthy controls (n = 1,843). Participants completed, between 2016 and 2017, a background questionnaire, together with the Implicit Association Test (IAT), measuring implicit associations between high-fat (vs. low-fat) food and shame (vs. acceptableness). Linear regression models were conducted to examine cross-sectional differences between groups. RESULTS Women with prior EDs had stronger implicit associations relative to healthy controls (p = 0.041) and similar implicit associations relative to women with current EDs (p = 0.424). DISCUSSION The implicit association between high-fat food and shame may not diminish over time among women with EDs. Future longitudinal studies are warranted to clarify whether an experience of EDs may leave a "scar," manifested in specific implicit associations, that may potentially lead to recurrence after remission.

Associations between naturalistically assessed physical activity patterns, affect, and eating in youth with overweight and obesity. J Behav Med 2020; 43:916-931.

Abstract
Insufficient physical activity (PA) and excessive stationary behavior (SB) are contributors to pediatric obesity, though antecedents and consequences of these behaviors in this population are relatively unknown. This pilot study examined affect, loss of control eating (LOCE), overeating, and hunger surrounding PA and SB in 17 youth with overweight/obesity. Participants completed a 14-day ecological momentary assessment (EMA) wearing accelerometers. At the momentary level, higher negative affect and lower positive affect predicted SB increases and PA decreases following EMA prompts; higher PA and lower SB also predicted increases in positive affect. Higher LOCE predicted SB increases and PA decreases, while increases in PA and decreases in SB predicted short-term increases in LOCE and overeating. At the individual level, higher SB and lower PA were related to lower positive affect and higher negative affect, LOCE, overeating, and hunger. Findings suggest affect is a relevant antecedent and consequence of PA/SB, and dysregulated eating may acutely impact PA/SB.

The utility of DSM-5 indicators of loss of control eating for the bariatric surgery population. EUROPEAN EATING DISORDERS REVIEW 2020; 28:423-432. [PMID: 32246543 DOI: 10.1002/erv.2737] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 01/27/2020] [Accepted: 03/16/2020] [Indexed: 11/08/2022]
Abstract
OBJECTIVES This study investigated the utility of DSM-5 indicators of loss of control (LOC) eating in adult bariatric surgery patients who presented with binge-eating episodes. METHODS Participants (all women) were 40 preoperative and 28 postoperative bariatric surgery patients reporting objective binge eating (OBE), 46 preoperative and 52 postoperative with subjective binge-eating (SBE), 53 bulimia nervosa (BN) controls, and 34 binge-eating disorder (BED) controls. Face-to-face Eating Disorder Examination interviews and questionnaires were administered. ANOVA, T-test, χ 2 , and regressions compared the groups in terms of LOC indicators endorsed and to explain disordered eating psychopathology. RESULTS The indicator most commonly reported by bariatric patients with OBE was "feeling disgusted" (90% and 75% of pre- and postoperative groups), and the least endorsed was "eating alone" (40 and 28.6%). These indicators were reported by >84.9% of the BN and BED. Bariatric patients (pre- or post-surgery) with OBE only reported a higher number of indicators than patients with SBE only (t(150) = 2.34, p = .021). A higher number of indicators reported were associated with increased eating-related psychopathology (F(1,134) = 31.06, p < .001), but only for the post-surgery patients. CONCLUSIONS The LOC indicators proposed by DSM-5 need to be refined or revised for the bariatric population. Highlights Bariatric patients endorse fewer LOC indicators than BN or BED during a binge-eating episode. Some of the DSM-5 LOC indicators may not be suited to assess episodes of loss of control eating among bariatric patients. The Higher the number of LOC indicators reported, the higher the eating-related psychopathology.

Abstract
BACKGROUND Eating disorders (EDs) are psychiatric illnesses with high rates of morbidity and mortality. Healthcare providers often receive inadequate training in evidence-based ED assessment and treatment. DESIGN Project CORE (Creating Opportunities for Rhode Island Eating Disorders Professionals) was developed to disseminate ED training/education and treatment approaches to the healthcare workforce. An interdisciplinary research team partners with pediatric healthcare professionals/trainees and supports them to better understand how to diagnose, manage, and collaborate across disciplines in the care of patients with EDs. METHODS Phase I involves a needs assessment of pediatric healthcare professionals' knowledge, attitudes and needs in treating EDs. Phase II involves the development of training/education approaches, and therapeutic interventions for patients with EDs. In Phase III approaches/interventions are further developed and disseminated across RI. PRINCIPAL CONCLUSIONS Project CORE's goals will address barriers to effective ED treatment in RI and broaden the workforce of interdisciplinary providers trained to recognize and treat patients with EDs across multiple healthcare settings.

A Pilot Study of Neural Correlates of Loss of Control Eating in Children With Overweight/Obesity: Probing Intermittent Access to Food as a Means of Eliciting Disinhibited Eating. J Pediatr Psychol 2019; 43:846-855. [PMID: 29462339 DOI: 10.1093/jpepsy/jsy009] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2017] [Accepted: 02/01/2018] [Indexed: 11/12/2022] Open
Abstract
Objective Neural substrates of loss of control (LOC) eating are undercharacterized. We aimed to model intermittent access to food to elicit disinhibited eating in youth undergoing neuroimaging, given evidence that restricted food access may increase subsequent food intake via enhancing reward value of food and diminishing eating-related self-control. Methods Participants were 18 preadolescents (aged 9-12 years) who were overweight/obese with recent LOC eating (OW-LOC; n = 6); overweight/obese with no history of LOC eating (OW-CON; n = 5); or non-overweight with no history of LOC eating (NW-CON; n = 7). Participants underwent functional magnetic resonance imaging during a simulated food restriction paradigm in which they were alternately given restricted or unrestricted access to milkshake solutions. Results There were no significant main effects of restricted versus unrestricted access to milkshake flavors. Group main effects revealed increased activation for OW-LOC relative to OW-CON in areas related to attentional processes (right middle frontal gyrus), inhibitory control/attentional shifts (right and left cuneus), and emotion regulation (left cingulate gyrus); and for OW-LOC relative to NW-CON in areas related to response inhibition (right inferior frontal gyrus). Significant block type × group interaction effects were found for the right middle frontal gyrus, left cingulate gyrus, and left cuneus, but these appeared to be accounted for primarily by group. Discussion There were clear group differences in neural activity in brain regions related to self-regulation during a food restriction paradigm. Elevations in these regions among OW-LOC relative to OW-CON and NW-CON, respectively, may suggest that youth with LOC eating expended more cognitive effort to regulate ingestive behavior.

Abstract
OBJECTIVE Eating pathology is more prevalent among women compared to men, but prevalence and correlates associated with eating pathology likely vary among subgroups of women. This study examines prevalence and correlates of restrictive and weight control-related eating pathology in sexual minority women. METHOD Data were collected from the Pittsburgh Girls Study (PGS). Participants reported on sexual orientation, and race, and body mass index (BMI) was derived from interviewer collected height and weight. Participants completed the Body Image Measure and the Eating Attitudes Test-26. RESULTS Sexual minority women reported higher BMIs [F (1, 862) = 14.69, p < .001], higher levels of body dissatisfaction [F (1, 960) = 3.12, p < .01], and higher levels of eating pathology [F (1, 950) = 14.21, p < .001] than heterosexual women. Body dissatisfaction mediated the relationship between BMI and eating pathology, and levels of associations were not attenuated by sexual minority status. Race moderated the association between sexual orientation and eating pathology; compared to all other groups, White sexual minority women had the highest level of eating pathology. Discussion Results indicate that White sexual minority women have higher levels of eating pathology than Black sexual minority women and both Black and White heterosexual women. Future studies that draw from larger and more diverse, community-based samples are needed.

Differences in risk factors for binge eating by socioeconomic status in a community-based sample of adolescents: Findings from Project EAT. Int J Eat Disord 2019; 52:659-668.

Abstract
OBJECTIVE Binge eating is prevalent across socioeconomic status (SES) groups, but it is unclear whether risk factors for binge eating vary by SES. This study examined the prevalence of several risk factors for binge eating by SES and SES as a potential moderator of these risk factors. METHOD Participants included 2,179 individuals involved in Project EAT during early/middle adolescence (EAT-I) and 5 years later during late adolescence/emerging adulthood (EAT-II). Risk ratios were computed using modified Poisson regression of incident EAT-II binge eating on EAT-I risk factors among participants of high and low SES. Interactions between each risk factor and SES were tested. RESULTS Among higher SES adolescents, overweight/obesity (RR = 3.2; 95% CI: 1.8, 5.7), body dissatisfaction (RR = 2.6; 95% confidence intervals (CI): 1.2, 5.5), dieting (RR = 4.0; 95% CI: 2.0, 8.2), and family weight-teasing (RR = 2.3; 95% CI: 1.3, 4.3) predicted increased risk for binge eating. Among adolescents from low-SES backgrounds, overweight/obesity (RR = 1.5; 95% CI: 0.9, 2.5), dieting (RR = 2.2; 95% CI: 1.2, 3.9), and food insecurity (RR = 1.4; 95% CI: 0.7, 2.7) predicted increased risk for binge eating. Moderator analyses revealed that overweight/obesity, body dissatisfaction, dieting, and family weight-teasing were stronger risk factors in the high-SES group than the low-SES group; interactions with food insecurity could not be examined given the low prevalence of food insecurity in the high-SES group. DISCUSSION Risk factors for binge eating may vary by SES, suggesting the potential utility of modifying intervention and prevention methods based on SES. In particular, the role of food insecurity must be addressed.

Trait-level facets of impulsivity and momentary, naturalistic eating behavior in children and adolescents with overweight/obesity. J Psychiatr Res 2019; 110:24-30. [PMID: 30580080 PMCID: PMC6360116 DOI: 10.1016/j.jpsychires.2018.12.018] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 12/12/2018] [Accepted: 12/14/2018] [Indexed: 01/08/2023]
Abstract
Impulsivity, and specific subdomains of inhibitory control and reward sensitivity, are trait-level factors that have been implicated in the onset and maintenance of pediatric obesity and disordered eating, but their associations with real-world eating behavior are unknown. We investigated associations of these trait-level constructs with naturalistic, momentary measures of loss of control (LOC) eating and overeating severity in a heterogeneous sample of youth (n = 40), aged 8-14y, with overweight/obesity. Self-report, parent-report, and behavioral data on trait-level impulsivity, reward sensitivity, and inhibitory control, respectively, were collected in the context of a 14-day ecological momentary assessment (EMA) protocol in which participants reported on their eating behavior, mood, hunger, and palatability of foods consumed in real-time. Generalized estimating equations revealed that more perseverative errors on a behavioral measure of visuomotor processing speed and a lower self-reported tendency to act without thinking (at a trend level) were related to greater overall LOC severity. Momentary associations between negative affect and LOC severity were stronger among individuals with greater perseverative errors. Results suggest that trait-level facets of impulsivity may directly influence an individual's tendency to engage in dysregulated eating behaviors, and may also impact susceptibility to state-level factors associated with occurrence of these behaviors. Momentary interventions for LOC eating may require tailoring to address temperamental factors related to impulsivity and inhibitory control.

Abstract
BACKGROUND Research suggests that substance use disorders and disordered eating are often comorbid. In light of the ongoing opioid epidemic, the purpose of the current study was to understand the prevalence and health-related correlates of loss of control (LOC) eating in adults seeking methadone maintenance treatment primarily for addiction to heroin and/or painkillers. METHODS Participants were 447 adults surveyed at presentation for methadone maintenance treatment who responded to survey items on LOC eating. Descriptive statistics were used to investigate the prevalence of engaging in LOC eating in the past 2 weeks. Chi-square tests, t tests, and analyses of covariance were used to compare individuals with (LOC+; n = 164) and without (LOC-; n = 283) recent LOC eating on psychosocial, pain-related, and weight-related characteristics. RESULTS Approximately one third of respondents endorsed LOC eating in the past 2 weeks. These participants reported greater affective symptoms, interpersonal dysfunction, pain intensity, and pain interference than the LOC- group (Cohen's d effect size range = .24-.94). LOC+ was also more likely to have engaged in recent illicit drug use and to report having concurrent overweight/obesity (φ effect size range = .09-.10). CONCLUSION The prevalence of LOC eating in adults seeking methadone maintenance treatment was more than triple what has been reported in previous studies using community samples. Given its associations with other health-related variables, the presence of LOC eating may be a marker for more severe psychopathology in individuals seeking methadone maintenance treatment. Future research is needed to understand mechanisms explaining this comorbidity and to develop novel ways to prevent and treat their co-occurrence.

Abstract
OBJECTIVE Given that weight gain patterns in adolescents receiving outpatient Family-Based Treatment (FBT) have not been characterized, the purpose of this study was to examine trajectories of weight gain in a group of adolescent patients with a restrictive eating disorder [e.g., anorexia nervosa (AN) and atypical AN] receiving FBT. This study also examined the association of patient characteristics with weight gain trajectories, including age, diagnosis, weight suppression, presenting BMI-for-age percentile, and eating pathology. METHOD Latent growth mixture modeling was used to identify distinct weight trajectories, as defined by change in BMI-for-age percentile, for 153 adolescents with AN or atypical AN, receiving FBT. RESULTS There were five distinct weight gain trajectory profiles for adolescents receiving FBT for a restrictive eating disorder. Younger age and greater weight suppression were associated with more rapid weight gain trajectories. A pattern of slow and consistent weight gain was associated with older age and less eating pathology. DISCUSSION There was considerable variability in weight gain trajectories in youth receiving outpatient FBT for a restrictive eating disorder. This suggests that patients' presenting information can be used to inform expectations regarding weight gain trajectories.

Abstract
Classifying eating disorders in youth is challenging in light of developmental considerations and high rates of diagnostic migration. Understanding the transactional relationships among eating disorder symptoms, both across the transdiagnostic spectrum and within specific diagnostic categories, may clarify which core eating disorder symptoms contribute to, and maintain, eating-related psychopathology in youth. We utilized network analysis to investigate interrelationships among eating disorder symptoms in 636 treatment-seeking children and adolescents (90.3% female) ages 6-18 years (M age = 15.4 ± 2.2). An undirected, weighted network of eating disorder symptoms was created using behavioral and attitudinal items from the Eating Disorder Examination. Across diagnostic groups, symptoms reflecting appearance-related concerns (e.g., dissatisfaction with shape and weight) and dietary restraint (e.g., a desire to have an empty stomach) were most strongly associated with other eating disorder symptoms in the network. Binge eating and compensatory behaviors (e.g., self-induced vomiting) were strongly connected to one another but not to other symptoms in the network. Network connectivity was similar across anorexia nervosa, bulimia nervosa, and otherwise specified feeding or eating disorder subgroups. Among treatment-seeking children and adolescents, dietary restraint and shape- and weight-related concerns appear to play key roles in the psychopathology of eating disorders, supporting cognitive-behavioral theories of onset and maintenance. Similarities across diagnostic categories provide support for a transdiagnostic classification scheme. Clinical interventions should seek to disrupt these symptoms early in treatment to achieve maximal outcomes. (PsycINFO Database Record

Abstract
INTRODUCTION Anorexia nervosa (AN) is a serious psychiatric disorder that is difficult to treat and often follows a protracted course. A number of theoretical models have been proposed for the etiology and maintenance of AN. Two domains that have received substantial attention in the literature on AN are affect and reward/punishment processes. However, despite an overlap in the nature and implications of these processes, studies of AN addressing these constructs have typically investigated them independently. PURPOSE The purpose of this narrative review is to integrate the literature on the role of affect, reward, and punishment in AN. METHOD We provide a focused narrative overview of the literature relating to the affect, reward, and punishment in AN via a synthesis of recent reviews and meta-analyses. RESULTS We first describe several prominent affect and reward/punishment-based conceptualizations of AN, followed by a brief overview of the existing empirical literature in these domains. CONCLUSION We provide a critical discussion of the disparate nature of these literatures in AN, including associated limitations. We then conclude with an extensive discussion of directions for future research that integrate the study of affect and reward/punishment processes in AN. LEVEL OF EVIDENCE Level V, narrative review.

Personal, behavioral, and environmental predictors of healthy weight maintenance during the transition to adulthood. Prev Med 2018; 113:80-90.

Abstract
There is a high prevalence of overweight among U.S. young adults and the intergenerational implications of excess weight gain at this life stage are great. We used Project EAT (Eating and Activity in Teens and Young Adults) study data to identify personal, behavioral, and environmental factors that predicted healthy weight maintenance during the transition from adolescence to adulthood and as individuals progressed from the third to fourth decade of life. The sample included 1120 young adults who were secondary school students in Minneapolis-St. Paul at Time 1 (1998-1999) and responded at follow-ups in 2008-2009 and 2015-2016. Results showed individual factors and multiple environmental factors contribute to maintenance. The most consistent findings suggest that having higher body satisfaction and avoiding unhealthy weight control behaviors (e.g., skipping meals) and dieting are protective against excess weight gain for women and men. For example, the odds ratio associated with a one standard deviation increase in the probability of using an extreme weight control behavior from adolescence and adulthood was 0.67 (CI: 0.54, 0.84) among women and 0.34 (CI: 0.12, 0.96) among men indicating decreased odds of maintaining a healthy weight. Social support for healthy eating and physical activity were protective whereas close relationships with individuals who were dieting (e.g., parents, significant others) reduced the likelihood of maintaining a healthy weight. Primary prevention strategies should continue beyond adolescence and involve peer social support to encourage young people at a healthy weight to be satisfied with their shape/size and avoid restrictive weight control behaviors.

Abstract
OBJECTIVES Contextual factors related to maladaptive eating behavior in youth with overweight/obesity are poorly understood. This pilot study sought to elucidate immediate internal and external cues related to perceptions of overeating and loss of control (LOC) over eating in a heterogeneous sample of children and adolescents with overweight/obesity assessed in their natural environments. METHOD Community-based youth [N = 40; 55% female (n = 22)], aged 8-14 y (M age = 11.2 ± 1.9 y), with overweight/obesity (M z-BMI = 2.07 ± 0.49) reported on all eating episodes and their physiological, environmental, affective, and interpersonal antecedents and correlates via ecological momentary assessment over a 2-week period. Generalized estimating equations were used to assess the relationship between contextual variables and degree of overeating and LOC. RESULTS Eating occasions involving greater food hedonics (i.e., perceived palatability of food being consumed) were associated with greater LOC severity (within-subjects effect: B = 0.01, p = .015), although youth with lower overall levels of food hedonics reported higher LOC severity ratings on average (between-subjects effect: B = -0.04, p = .005). Youth reporting higher overall cravings reported higher average ratings of LOC severity (between-subjects effect: B = 0.20, p = .001). Finally, youth reporting greater overall influence of others on eating behavior evidenced greater average levels of overeating severity (between-subjects effect: B = 0.17, p < .001). DISCUSSION Eating-related factors appear to be most strongly associated with LOC severity, while environmental factors were most associated with overeating severity. Interventions targeting maladaptive eating in youth with overweight/obesity may benefit from helping youth incorporate palatable foods and satisfy cravings in a planned and controlled manner, and enhancing awareness of social-contextual effects on eating.

Outcome parameters associated with perceived helpfulness of family-based treatment for adolescent eating disorders. Int J Eat Disord 2018; 51:574-578. [PMID: 29637574 PMCID: PMC7371332 DOI: 10.1002/eat.22863] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Revised: 03/12/2018] [Accepted: 03/12/2018] [Indexed: 11/07/2022]
Abstract
OBJECTIVE Family-based treatment (FBT) is an efficacious treatment for adolescent eating disorders, yet it is not routinely implemented in clinical practice. Given that consumers play a role in treatment selection, this study sought to examine families' perspectives on FBT and remission markers associated with increased treatment satisfaction across families. METHOD Participants were 40 adolescents and 43 caregivers who received outpatient FBT. FBT helpfulness was assessed using a treatment follow-up questionnaire, and eating disorder symptomatology was assessed using percent expected body weight (%EBW) and the eating disorder examination (EDE). Regression analyses were used to assess whether changes in symptoms from baseline to end-of-treatment (EOT) were significantly associated with helpfulness reports. RESULTS On average, patients and their parents perceived FBT as "quite helpful" and "extremely helpful," respectively. Improvements in all EDE subscales, with the exception of restraint, were significantly associated with adolescent report of helpfulness (all p < .05); increase in %EBW was significantly associated with maternal report of helpfulness (p = .03). There were no significant findings for paternal report. DISCUSSION Both patients and their parents perceived FBT as helpful, but patients seemed to prioritize cognitive improvements while mothers prioritized physical improvements in rating their satisfaction with FBT.

Abstract
Perfectionism is hypothesized to contribute to the etiology of anorexia nervosa (AN). However, there is little research regarding whether individuals with AN can be classified according to maladaptive (e.g., evaluative concerns) and adaptive (e.g., high personal standards) facets of perfectionism that predict distinct outcomes and might warrant different intervention approaches. In this study, a latent profile analysis was conducted using data from adults with AN (n = 118). Frost Multidimensional Perfectionism Scale (Frost et al. Cognitive Therapy and Research, 14(5), 449-46, 1990) subscales were used to identify subgroups differing according to endorsed perfectionism features (e.g., adaptive and maladaptive perfectionism). Generalized linear models were used to compare subgroups on eating disorder and affective symptoms measured through questionnaire and ecological momentary assessment. Four subgroups were identified: (a) Low Perfectionism; (b) High Adaptive and Maladaptive Perfectionism; (c) Moderate Maladaptive Perfectionism; and (d) High Maladaptive Perfectionism. Subgroups differed on overall eating disorder symptoms (p < .001), purging (p = .005), restrictive eating (p < .001), and body checking (p < .001) frequency, depressive (p < .001) and anxiety (p < .001) symptoms, and negative (p = .001) and positive (p < .001) affect. The Low Perfectionism group displayed the most adaptive scores and the Moderate and High Maladaptive Perfectionism groups demonstrated the most elevated clinical symptoms. The High Adaptive and Maladaptive Perfectionism group demonstrated low affective disturbances, but elevated eating disorder symptoms. Results support the clinical significance of subtyping according to perfectionism dimensions in AN. Research is needed to determine if perfectionism subtyping can enhance individualized treatment targeting in AN.

Examining Two Prevailing Models of Loss of Control Eating Among Community-Based Girls. Obesity (Silver Spring) 2018; 26:420-425. [PMID: 29280308 PMCID: PMC5783779 DOI: 10.1002/oby.22101] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2017] [Revised: 11/28/2017] [Accepted: 11/28/2017] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Cognitive-behavioral and interpersonal models of loss of control (LOC) eating have been underexplored in adolescents. METHODS By using data from community-based adolescent girls assessed annually over 4 years, the cognitive-behavioral (n = 416) and interpersonal (n = 418) models were examined by using a regression-based bootstrapping approach. RESULTS Body dissatisfaction at 14 years prospectively predicted LOC eating at 18 years, both directly (direct effect = -0.039; SE = 0.017; P = 0.02) and indirectly via dieting (indirect effect = -0.010; 95% CI: -0.022 to -0.003). Interpersonal functioning at 14 years was negatively associated with negative emotionality at 17 years, which, in turn, was prospectively associated with LOC eating at 18 years (indirect effect = 0.001; 95% CI: -0.001 to -0.0003); however, the direct association between age 14 interpersonal functioning and age 18 LOC eating was not significant (direct effect = -0.001; SE = 0.001; P = 0.47). CONCLUSIONS These findings support the cognitive-behavioral model, and partially support the interpersonal model, with the latter findings implying that over time, negative emotionality may promote LOC eating independent of the effects of prior social functioning. Prevention and early intervention efforts for LOC eating may benefit from integrating these theoretical frameworks.

Adolescent Loss-of-Control Eating and Weight Loss Maintenance After Bariatric Surgery. Pediatrics 2018; 141:peds.2017-1659. [PMID: 29237801 PMCID: PMC5744387 DOI: 10.1542/peds.2017-1659] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/18/2017] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Loss-of-control (LOC) eating is common in adults undergoing bariatric surgery and is associated with poorer weight outcomes. Its long-term course in adolescent bariatric surgery patients and associations with weight outcomes are unclear. METHODS Adolescents (n = 234; age range = 13-19 years) undergoing bariatric surgery across 5 US sites were assessed for postsurgery follow-up at 6 months and 1, 2, 3, and 4 years. Descriptive statistics and generalized linear mixed models were used to describe the prevalence of LOC eating episodes involving objectively large amounts of food and continuous eating, respectively. Generalized linear mixed models investigated the association of any LOC eating with short- and long-term BMI changes. RESULTS At baseline, objectively large LOC eating was reported by 15.4% of adolescents, and continuous LOC eating by 27.8% of adolescents. Both forms of LOC eating were significantly lower at all postsurgical time points relative to presurgery (range = 0.5%-14.5%; Ps < .05). However, both behaviors gradually increased from 6-month to 4-year follow-up (Ps < .05). Presurgical LOC eating was not related to percent BMI change over follow-up (P = .79). However, LOC eating at 1-, 2-, and 3-year follow-up was associated with lower percent BMI change from baseline at the next consecutive assessment (Ps < .05). CONCLUSIONS Although presurgical LOC eating was not related to relative weight loss after surgery, postoperative LOC eating may adversely affect long-term weight outcomes. Rates of LOC eating decreased from presurgery to 6-months postsurgery but increased thereafter. Therefore, this behavior may warrant additional empirical and clinical attention.

Abstract
It has been theorized that state the levels of self-control depletion (as caused by negative affect and restraint) may lead to binge eating (BE) when individuals also endorse momentary expectancies that eating will make them feel better (EE). Given commonalities in precipitants of BE across populations, the current study tested this theory in a sample of adults with obesity using ecological momentary assessment (EMA). Fifty obese adults completed the EMA protocol during which they provided pre-eating episode ratings of negative affect, restraint, and EE, and post-eating episode ratings of BE. Generalized estimating equations (GEE) identified a 3-way interaction between within-person pre-eating episode variables: higher self-control depletion (e.g., higher restraint and higher negative affect) was predictive of BE episodes only when individuals also endorsed higher EE. To our knowledge, this is the first empirical test of this theory, highlighting the impact of momentary self-control depletion and EE on BE in obese adults.

Attention-Deficit/Hyperactivity Disorder Symptoms Are Associated with Overeating with and without Loss of Control in Youth with Overweight/Obesity. Child Obes 2018; 14:50-57.

Abstract
BACKGROUND There is growing evidence that attention-deficit/hyperactivity disorder (ADHD) and loss of control (LOC) eating, both prevalent in children and adolescents, may be related to one another. However, the relationship between ADHD and overeating without LOC has been largely unexamined, thus precluding an understanding of the independent contributions of LOC and episode size in these associations. The current study sought to examine associations between ADHD symptoms and maladaptive eating by evaluating three different types of eating episodes characterized by the presence/absence of LOC and the amount of food consumed: objectively large LOC episodes [objective binge eating (OBE)], subjectively large binge episodes [subjective binge eating (SBE)], and objectively large overeating episodes without LOC [objective overeating (OO)]. METHODS Participants were 385 youth (M age = 10.89, SD = 2.25) drawn from five different research protocols at institutions across the United States. Participants and their parents completed questionnaires and semistructured interviews to assess ADHD symptoms, OBE, SBE, and OO. RESULTS As hypothesized, negative binomial regressions revealed that ADHD symptoms were significantly associated with OBE, χ2(1) = 16.61, p < 0.001, and with OO, χ2(1) = 10.64, p < 0.01. Contrary to expectations, they were not associated with SBE. CONCLUSIONS These results indicate the need for future studies to explore possible shared mechanisms (e.g., impulsivity) underlying associations between ADHD symptoms, OBE, and OO. Clinical implications include support for considering ADHD symptoms in programs that target both prevention of LOC eating and obesity more generally.
