Binge eating in overweight treatment-seeking adolescents

A Pilot Randomized Control Trial Testing a Smartphone-Delivered Food Attention Retraining Program in Adolescent Girls with Overweight or Obesity

BACKGROUND/OBJECTIVES

Attention bias (AB) toward food is associated with obesity, but it is unclear if programs designed to reduce AB can impact adolescents' eating behavior. We investigated whether a two-week, smartphone-delivered attention retraining (AR) program (vs a control program) altered food AB in adolescent girls with overweight.

METHODS

Participants completed three food-cue visual-probe trainings/day. The AR and control programs directed attention away from food stimuli during 100% and 50% of trainings, respectively. Before and after completion of the programs, girls completed a food-cue visual-probe task while undergoing magnetoencephalography (MEG), and then a laboratory test meal.

RESULTS

Sixty-eight adolescents were randomized; 58 completed post-program visits. There was minimal effect of condition on AB scores (β [95%CI] = -1.9 [-20.8, 16.9]; d = -0.06). There was a small effect of condition on energy intake (EMMcontrol = 1017 kcal, EMMAR = 1088 kcal, d = 0.29). Within the AR group, there was slightly blunted initial engagement in brain areas associated with reward response and subsequent increased goal-directed attention and action control.

CONCLUSIONS

We found preliminary support for efficacy of an intensive smartphone-delivered AR program to alter neural correlates of attention processing in adolescent girls with overweight or obesity. Studies with larger sample sizes are needed to elucidate if AR trainings disrupt the link between food AB and eating behavior.

Trauma-Focused Cognitive-Behavioral Therapy for Adolescents Bullied Because of Weight: A Feasibility Study

OBJECTIVE

The objective of this study was to test the feasibility and acceptability of a treatment for weight bullying.

METHOD

Participants who had experienced weight-related bullying and were currently experiencing traumatic stress were recruited and enrolled in a feasibility trial of trauma-focused cognitive behavioral therapy combined with cognitive-behavioral therapy for eating disorders (TF-CBT-WB). Thirty adolescents (aged 11-17) were determined eligible and 28 began treatment (12 weeks).

RESULTS

This study demonstrated the treatment feasibility and acceptability of TF-CBT-WB for adolescents with traumatic stress following weight-bullying experiences. Overall retention and treatment satisfaction were good. Within-subjects improvements were observed for intrusion symptoms of traumatic stress, global eating-disorder severity, overvaluation of weight/shape, dissatisfaction with weight/shape, dietary restraint, and depression. Clinically-meaningful improvements were attained for several patient outcomes. Clinically-meaningful decreases in functional impairment were attained by more than half of the participants.

CONCLUSIONS

Overall, this clinical trial testing TF-CBT-WB for adolescents experiencing traumatic stress following weight-bulling experiences demonstrated therapy feasibility, acceptability, and initial evidence that clinically-meaningful improvements in patient outcomes were feasible. However, some patient outcomes thought to be more central to how the youth viewed the world failed to show improvements, suggesting that additional content related to these constructs might yield greater benefit.

A brief bout of moderate intensity physical activity improves preadolescent children's behavioral inhibition but does not change their energy intake

Children in rural communities consume more energy-dense foods relative to their urban peers. Identifying effective interventions for improving energy intake patterns are needed to address these geographic disparities. The primary aim of this study was to harness the benefits of physical activity on children's executive functioning to see if these improvements lead to acute changes in eating behaviors. In a randomized crossover design, 91 preadolescent (8-10y; M age = 9.48 ± 0.85; 50.5% female; 85.7% White, 9.9% Multiracial, 9.9% Hispanic) children (86% rural) completed a 20-minute physical activity condition (moderate intensity walking) and time-matched sedentary condition (reading and/or coloring) ~ 14 days apart. Immediately following each condition, participants completed a behavioral inhibition task and then eating behaviors (total energy intake, relative energy intake, snack intake) were measured during a multi-array buffet test meal. After adjusting for period and order effects, body fat (measured via DXA), and depressive symptoms, participants experienced significant small improvements in their behavioral inhibition following the physical activity versus sedentary condition (p = 0.04, Hedge's g = 0.198). Eating behaviors did not vary by condition, nor did improvements in behavioral inhibition function as a mediator (ps > 0.09). Thus, in preadolescent children, small improvements in behavioral inhibition from physical activity do not produce acute improvements in energy intake. Additional research is needed to clarify whether the duration and/or intensity of physical activity sessions would produce different results in this age group, and whether intervention approaches and corresponding mechanisms of change vary by individual factors, like age and degree of food cue responsivity.

Treatment of Binge-Eating Disorder Across the Lifespan: An Updated Review of the Literature and Considerations for Future Research

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.

Long-term changes in eating-related problems and quality of life in children with overweight and obesity attending a 10-week lifestyle camp

BACKGROUND

Eating-related problems (e.g., binge eating (BE)) and impaired quality of life (QoL) is more prevalent in children with overweight and obesity. This study aimed to investigate changes in self-reported overeating (OE), BE, and QoL in children with overweight or obesity attending multicomponent 10-week lifestyle camps with a 52-weeks follow-up. Additionally, the study sought to investigate whether self-reported OE/BE before camp was associated with changes in QoL.

METHODS

Children aged 7 to 14-years could attend camp if they had overweight/obesity, were lonely, unhappy, or had social or family-related problems. In this study only children with overweight and obesity were included (n:185). OE, BE, and QoL were measured using self-reported questionnaires.

RESULTS

In total, 38 % of the children reported regular BE at baseline. Regular OE, occasional BE, and occasional OE was reported by 14 %, 13 %, and 11 %, respectively, while 24 % reported no eating-related problems. The relative risk of experiencing eating-related problems decreased at 10-weeks compared to baseline. Additionally, the probability of regular OE (RR 0.12 (95 % CI 0.04;0.38) (X2 = 8.44, p = 0.004)) and regular BE (RR 0.01 (95 % CI 0.00;0.11) (X2 = 9.91, p = 0.002)) remained lower at 52-weeks relative to baseline. All QoL dimensions improved after camp, and the presence of self-reported OE and regular BE at baseline was significantly associated with lower QoL at baseline, 10 and 52-weeks.

CONCLUSION

Children self-reporting OE and BE may be a particular vulnerable group that needs more support from camp staff and healthcare professionals to improve QoL.

Binge-eating adolescent treatment (BEAT) - findings from a pilot study on effects and acceptance of a blended treatment program for youth with loss of control eating

BACKGROUND

Loss of Control Eating (LOC) is the most prevalent form of eating disorder pathology in youth, but research on evidence-based treatment in this group remains scarce. We assessed for the first time the effects and acceptance of a blended treatment program for youth between 14 and 24 years with LOC (Binge-eating Adolescent Treatment, BEAT).

METHODS

Twenty-four youths (mean age 19.1 years) participated in an active treatment of nine-weeks including three face-to-face workshops and six weekly email-guided self-help sessions, followed by four email guided follow-up sessions, one, three, six and 12 months after the active treatment. All patients completed a two-weeks waiting-time period before treatment begin (within-subject waitlist control design).

RESULTS

The number of weekly LOC episodes substantially decreased during both the waiting-time (effect size d = 0.45) and the active treatment (d = 1.01) period and remained stable during the subsequent 12-months follow-up (d = 0.20). The proportion of patients with full-threshold binge-eating disorder (BED) diagnoses decreased and transformed into LOC during the study course, while the abstainer rate of LOC increased. Values for depressive symptoms (d = 1.5), eating disorder pathology (d = 1.29) and appearance-based rejection sensitivity (d = 0.68) all improved on average from pretreatment to posttreatment and remained stable or further improved during follow-up (d between 0.11 and 0.85). Body weight in contrast remained constant within the same period. Treatment satisfaction among completers was high, but so was the dropout rate of 45.8% at the end of the 12-months follow-up.

CONCLUSIONS

This first blended treatment study BEAT might be well suited to decrease core symptoms of LOC, depressive symptoms and appearance-based rejection sensitivity. More research is needed to establish readily accessible interventions targeted more profoundly at age-salient maintaining factors such as appearance-based rejection sensitivity, while at the same time keeping dropout rates at a low level.

TRIAL REGISTRATION

The trial was registered at the German Clinical Trials Register (ID: DRKS00014580; registration date: 21/06/2018).

Characteristics of Malaysian 16-year-old girls who reported regular binge eating episodes and the associated risk factors: a descriptive study

OBJECTIVES

Adolescents may suffer from binge eating (BE), that refers to consuming a large amount of food in a short period of time and accompanied by feelings of loss of control (LOC) over eating. This study compared the prevalence of BE between 16-year-old Malaysian girls from two types of public schools, Malay-English-medium and Chinese-Malay-English-medium schools. Additionally, this study identified associated risk factors of those who presented regular BE episodes, including LOC eating, anxiety, body mass index (BMI), body dissatisfaction (BD) and eating disorders (EDs) psychopathology.

METHODS

398 participants completed self-reports assessing BE symptoms, LOC eating, state anxiety, trait anxiety, EDs psychopathology, and BD. They also reported heights and weights. Descriptive statistics, t-tests, chi-square tests, and Z-test for independent proportions were conducted.

RESULTS

There was no significant difference in either the prevalence of BE or EDs psychopathology between participants from the two types of schools. 71 (17.8 %) participants reported moderate-to-severe symptoms of BE, and 46 (11.6 %) reported moderate-to-severe levels of LOC eating. Those who reported moderate-to-severe symptoms of BE reported significantly higher levels of LOC eating, BD, drive to be thinner, BMI, state anxiety, and EDs psychopathology, compared to those who reported none-to-minimal BE.

CONCLUSIONS

BE and LOC eating appeared to be relatively common among secondary school girls in Malaysia. The relatively high prevalence of BE amongst adolescents in our sample highlighted the importance of early identification of signs for BE as preventive measures from developing EDs psychopathology among children and adolescents. We propose that attitudes towards eating and body image-related concerns should be included in school screenings aimed at preventing psychological problems in minors.

Loss of control eating in relation to blood pressure among adolescent girls with elevated anxiety at-risk for excess weight gain

Loss of control (LOC)-eating, excess weight, and anxiety are robustly linked, and are independently associated with markers of poorer cardiometabolic health, including hypertension. However, no study has examined whether frequency of LOC-eating episodes among youth with anxiety symptoms and elevated weight status may confer increased risk for hypertension. We examined the relationship between LOC-eating frequency and blood pressure among 39 adolescent girls (14.9 ± 1.8 years; body mass index [BMI] = 29.9 ± 5.6; 61.5 % White; 20.5 % African American/Black; 5 % Multiple Races; 2.5 % Asian; 12.8 % Hispanic/Latino; 30.8 % with reported LOC-eating) with elevated anxiety and above average BMI who enrolled in a clinical trial aimed at preventing excess weight gain. LOC-eating over the past three months was assessed via clinical interview, and blood pressure (systolic and diastolic) was measured with an automatic blood pressure monitor. Adjusting for age, fat mass, and height, LOC-eating episode frequency was significantly, positively associated with diastolic blood pressure (β = 0.38, p = 0.02), but not with systolic blood pressure (β = 0.13, p = 0.41). Replication studies, with larger sample sizes, participants of varying weight-strata, and prospective data are required to elucidate the relationship between LOC-eating and cardiovascular functioning in youth with elevated anxiety.

Autonomic indices and loss-of-control eating in adolescents: an ecological momentary assessment study

BACKGROUND

Loss-of-control (LOC) eating commonly develops during adolescence, and it predicts full-syndrome eating disorders and excess weight gain. Although negative emotions and emotion dysregulation are hypothesized to precede and predict LOC eating, they are rarely examined outside the self-report domain. Autonomic indices, including heart rate (HR) and heart rate variability (HRV), may provide information about stress and capacity for emotion regulation in response to stress.

METHODS

We studied whether autonomic indices predict LOC eating in real-time in adolescents with LOC eating and body mass index (BMI) ⩾70th percentile. Twenty-four adolescents aged 12-18 (67% female; BMI percentile mean ± standard deviation = 92.6 ± 9.4) who reported at least twice-monthly LOC episodes wore biosensors to monitor HR, HRV, and physical activity for 1 week. They reported their degree of LOC after all eating episodes on a visual analog scale (0-100) using a smartphone.

RESULTS

Adjusting for physical activity and time of day, higher HR and lower HRV predicted higher self-reported LOC after eating. Parsing between- and within-subjects effects, there was a significant, positive, within-subjects association between pre-meal HR and post-meal LOC rating. However, there was no significant within-subjects effect for HRV, nor were there between-subjects effects for either electrophysiologic variable.

CONCLUSIONS

Findings suggest that autonomic indices may either be a marker of risk for subsequent LOC eating or contribute to LOC eating. Linking physiological markers with behavior in the natural environment can improve knowledge of illness mechanisms and provide new avenues for intervention.

Negative affect and loss-of-control eating in relation to adiposity among non-Hispanic youth identifying as black or white

Negative affect and loss-of-control (LOC)-eating are consistently linked and prevalent among youth identifying as non-Hispanic Black (NHB) and non-Hispanic White (NHW), particularly those with high weight. Given health disparities in high weight and associated cardiometabolic health concerns among NHB youth, elucidating how the association of negative affect with adiposity may vary by racial/ethnic group, and whether that relationship is impacted by LOC-eating, is warranted. Social inequities and related stressors are associated with negative affect among NHB youth, which may place this group at increased risk for excess weight gain. Across multiple aggregated protocols, 651 youth (13.0 ± 2.7 y; 65.9 % girls, 40.7 % NHB; 1.0 ± 1.1 BMIz; 37.6 % LOC-eating) self-reported trait anxiety and depressive symptoms as facets of negative affect. LOC-eating was assessed by interview and adiposity was measured objectively. Cross-sectional moderated mediation models predicted adiposity from ethno-racial identification (NHB, NHW) through the pathway of anxiety or depressive symptoms and examined whether LOC-eating influenced the strength of the pathway, adjusting for SES, age, height, and sex. The association between ethno-racial identity and adiposity was partially mediated by both anxiety (95 % CI = [0.01, 0.05]) and depressive symptoms (95 % CI = [0.02, 0.08]), but the mediation was not moderated by LOC-eating for either anxiety (95 % CI = [-0.04, 0.003]) or depressive symptoms (95 % CI = [-0.07, 0.03]). Mechanisms underlying the link between negative affect and adiposity among NHB youth, such as stress from discrimination and stress-related inflammation, should be explored. These data highlight the need to study impacts of social inequities on psychosocial and health outcomes.

Practical Considerations for Using the Eating Disorder Examination Interview with Adolescents

Approximately 35 years after its initial publication, the Eating Disorder Examination (EDE) remains one of the most widely used semi-structured interviews for assessing eating disorder diagnoses and symptomatology. Although the interview provides certain advantages over other common measurement approaches (ie, questionnaires), there are particular considerations regarding the EDE that warrant attention, including in its use with adolescents. The aims of this paper are therefore to: 1) provide a brief overview of the interview itself, as well as a description of its origin and underlying conceptual framework; 2) describe relevant factors for administering the interview with adolescents; 3) review potential limitations regarding use of the EDE with adolescents; 4) address considerations for using the EDE with pertinent subpopulations of adolescents who may experience distinct eating disorder symptoms and/or risk factors; and 5) discuss the integration of self-report questionnaires with the EDE. Advantages of using the EDE include the ability for interviewers to clarify complex concepts and mitigate inattentive responding, enhanced orientation to the interview timeframe to improve recall, increased diagnostic accuracy compared to questionnaires, and accounting for potentially salient external factors (eg, food/eating rules imposed by a parent/guardian). Limitations include more extensive training requirements, greater assessment burden, variable psychometric performance across subgroups, lack of items evaluating muscularity-oriented symptoms and avoidant/restrictive food intake disorder diagnostic criteria, and lack of explicit consideration for salient risk factors other than weight and shape concerns (eg, food insecurity).

Addressing Anxiety and Stress for Healthier Eating in Teens (ASSET): A Pilot Randomized Controlled Trial Protocol for Reducing Anxiety, Disinhibited Eating, Excess Weight Gain, and Cardiometabolic Risk in Adolescent Girls

(1) Background: Standard-of-care lifestyle interventions show insufficient effectiveness for the prevention and treatment of excess weight and its associated cardiometabolic health concerns in adolescents, necessitating more targeted preventative approaches. Anxiety symptoms are common among adolescents, especially girls at risk for excess weight gain, and have been implicated in the onset and maintenance of disinhibited eating. Thus, decreasing elevated anxiety in this subset of adolescent girls may offer a targeted approach to mitigating disinhibited eating and excess weight gain to prevent future cardiometabolic health problems. (2) Methods: The current paper describes the protocol for a multisite pilot and feasibility randomized controlled trial of group cognitive behavioral therapy (CBT) and group interpersonal psychotherapy (IPT) in N = 40 adolescent girls (age 12-17 years) with elevated anxiety symptoms and body mass index (BMI; kg/m2) ≥ 75th percentile for age/sex. (3) Results: Primary outcomes are multisite feasibility of recruitment, protocol procedures, and data collection, intervention fidelity, retention at follow-ups, and acceptability of interventions and study participation. (4) Conclusions: Findings will inform the protocol for a future fully-powered multisite randomized controlled trial to compare CBT and IPT efficacy for reducing excess weight gain and preventing adverse cardiometabolic trajectories, as well as to evaluate theoretically-informed treatment moderators and mediators.

Heart Rate Variability and Laboratory-Based Loss-of-Control Eating in Children and Adolescents

Among youth, greater heart rate (HR) and lesser HR variability (HRV) are precursors to loss-of-control (LOC) eating episodes in the natural environment. However, there are limited data examining whether pre-meal HR and HRV are associated with greater LOC-eating in the laboratory setting. We therefore examined temporal relationships between pre-meal HR, frequency- and time-based metrics of pre-meal HRV, perceived LOC-eating, and energy intake during a meal designed to simulate a LOC-eating episode. Among 209 participants (54.5% female, 12.58 ± 2.72 years, 0.52 ± 1.02 BMIz), 19 reported LOC-eating in the prior month. Perceived LOC-eating during the laboratory meal was not significantly linked to pre-meal HR (p = 0.37), but was positively related to pre-meal HRV (ps = 0.02–0.04). This finding was driven by youth with recent LOC-eating, as these associations were not significant when analyses were run only among participants without recent reported LOC-eating (p = 0.15–0.99). Pre-meal HR and HRV were not significantly related to total energy intake (ps = 0.27–0.81). Additional research is required to determine whether early-stage pediatric LOC-eating is preceded by a healthy pre-meal stress response. Longitudinal studies could help clarify whether this pattern becomes less functional over time among youth who develop recurrent LOC-eating episodes.

Examination of the Interaction between Parental Military-Status and Race among Non-Hispanic Black and Non-Hispanic White Adolescents with Overweight/Obesity

OBJECTIVES

Adolescent military-dependents experience distinct risk and protective factors, which may necessitate additional clinical considerations. In civilian youth, overweight/obesity is associated with eating, internalizing, and externalizing difficulties, with some studies reporting more difficulties among non-Hispanic White (vs. non-Hispanic Black) youth. It is unknown if these disparities exist among adolescent military-dependents, or between civilian and military-dependent youth.

METHODS

Non-Hispanic Black (187 civilian, 38 military-dependent) and non-Hispanic White (205 civilian, 84 military-dependent) adolescents with overweight/obesity (14.7 ± 1.6 years; 73.9% girls; body mass index adjusted for age and sex 1.9 ± 0.5) completed a disordered-eating interview; parents completed a measure assessing their child's internalizing and externalizing difficulties. Multiple linear regressions examined parental military-status as a moderator of the relationship of participant race with eating, internalizing, and externalizing difficulties.

RESULTS

White civilian youth with overweight/obesity reported significantly greater disordered-eating than their Black peers (p < .001); there were no other significant racial differences. In all regressions, parental military-status significantly moderated the association between race and each dependent variable (ps < .047). Black military-dependents (vs. civilians) reported more disordered-eating and internalizing difficulties (ps = .01). White military-dependents (vs. civilians) reported fewer externalizing difficulties (p = .01).

CONCLUSIONS

Black adolescent military-dependents with overweight/obesity may experience more eating and internalizing difficulties (vs. civilians), a pattern not observed among White participants. Future work should examine if being a military-dependent and a historically marginalized racial group member accounts for these findings. Such data may inform providers of youth with intersecting minority identities.

The Role of Affective Instability in Loss of Control Eating in Youth with Overweight/Obesity Across Development: Findings from Two EMA Studies

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.

The Relationship Between Anxiety, Coping, and Disordered-Eating Attitudes in Adolescent Military-Dependents at High-Risk for Excess Weight Gain

Adolescent military-dependents are an understudied population who face unique stressors due to their parents' careers. Research suggests that adolescent military-dependents report more anxiety and disordered-eating than their civilian counterparts. While anxiety symptoms predict the onset and worsening of disordered-eating attitudes, the mechanisms underlying this relationship remain unclear. One factor that may underlie this relationship, and be particularly relevant for military-dependent youth, is coping. Therefore, we examined adolescent military-dependents (N=136; 14.5±1.5 years; 59.6% female; BMI-z: 1.9±0.4) who were at-risk for adult obesity and binge-eating disorder due to an age- and sex-adjusted BMI ≥ 85th percentile and loss-of-control eating and/or elevated anxiety. Participants completed an interview assessing disordered-eating attitudes and questionnaires on anxiety symptoms and coping strategies at a single time point. Bootstrapping models were conducted to examine the indirect paths between anxiety symptoms and disordered-eating attitudes through five coping subscales (aggression, distraction, endurance, self-distraction, and stress-recognition). Adjusting for relevant covariates, no significant indirect paths through the coping subscales (ps > .05) were found in any models. General coping, non-specific to eating, may not be a pathway between anxiety symptoms and disordered-eating attitudes among adolescents. Future research should examine other potential mediators of this relationship.

Altered regional grey matter volume and appetite-related hormone levels in adolescent obesity with or without binge-eating disorder

PURPOSE

Binge eating disorder (BED) is characterized by frequent and persistent overeating episodes of binge eating without compensatory behaviors. The aim was to evaluate regional gray matter volume (GMV) abnormalities and appetite-regulating hormone levels (NPY and Leptin) in obese subjects either with or without BED compared to healthy controls (HC).

METHODS

Twenty-six obese patients with BED, 25 obese patients without BED and 27 healthy subjects as an age-matched control group with neuroimaging and appetite-regulating hormone levels were found eligible for regional GMV abnormalities. A structural magnetic resonance scan and timely blood samples were drawn to assess the appetite-regulating hormone levels.

RESULTS

The BED obese patients had a greater GMVs of the right medial orbitofrontal cortex (OFC) and the left medial OFC compared to the non-BED obese patients. BED patients were characterized by greater GMV of the left medial OFC than HCs. Relative to the HCs, higher serum NPY levels were found in BED obese and non-BED obese groups. Serum leptin levels (pg/mL) had positively correlations with GMV in right medial OFC, left medial OFC, right lateral OFC, and left anterior cingulate cortex.

CONCLUSION

Among the reward processing network, which is largely associated with feeding behaviours in individuals with obesity and binge eating disorder, the OFC volumes was correlated with serum leptin concentrations. The results of our study may provide a rationale for exploring the link between regional grey matter volumes and appetite-related hormone levels in people with BED.

Prevalence of binge-eating disorder among children and adolescents: a systematic review and meta-analysis

The objective is to estimate the prevalence of binge-eating disorder (BED) and subclinical BED in children and adolescents. Relevant articles were searched in the databases of PubMED and PsycINFO. Articles were included if they measured BED, subclinical BED, binge eating and/or loss of control (LOC) eating in samples of up to 20 years of age or with a mean age below 20 years. Subclinical BED covers participants with < 4 OBEs but ≥ 1 OBE pr. month and studies measuring subclinical DSM-IV/DSM-5 BED, but where all criteria were not met. All study types and measuring methods were accepted, but studies were excluded if they did not assess and exclude cases of recurrent compensatory behaviors. Meta-analyses were used to obtain an overall estimate of the prevalence of BED and subclinical BED, while stratified meta-analyses were used to assess sources of heterogeneity. 39 studies measuring BED, subclinical BED and/or a low frequency of binge eating were included. Two meta-analyses resulted in an overall estimated prevalence of 1.32% BED and 3.0% subclinical BED in children and adolescents. The results were influenced by high heterogeneity. Potential sources to heterogeneity in the BED result were weight of participants and sample types as well as level of risk of bias in the included studies. BED seems to be as frequent in children and adolescents as anorexia nervosa and bulimia nervosa. Hence, treatment of BED and BED symptoms in younger populations should be prioritized on the same terms as anorexia and bulimia nervosa.

General and Eating Disorder Psychopathology in Relation to Short- and Long-Term Weight Change in Treatment-Seeking Children: A Latent Profile Analysis

BACKGROUND

Concurrent general psychopathology (GP) and eating disorder psychopathology (EDP) are commonly reported among youth with overweight/obesity and may impact weight change.

PURPOSE

We identified patterns of GP and EDP in children with overweight/obesity and examined the impact on weight change following family-based behavioral obesity treatment (FBT) and maintenance interventions.

METHODS

Children (N = 172) participated in 4 month FBT and subsequent 8 month weight maintenance interventions. GP and EDP were assessed prior to FBT (baseline). Child percentage overweight was assessed at baseline, post-FBT (4 months), and post-maintenance (12 months). Latent profile analysis identified patterns of baseline GP and EDP. Linear mixed-effects models examined if profiles predicted 4- and 12-month change in percentage overweight and if there were two-way and three-way interactions among these variables, adjusting for relevant covariates.

RESULTS

Results indicated a three-profile structure: lower GP and EDP (LOWER); subclinically elevated GP and EDP without loss of control (LOC; HIGHER); and subclinically elevated GP and EDP with LOC (HIGHER + LOC). Across profiles, children on average achieved clinically meaningful weight loss (i.e., ≥9 unit change in percentage overweight) from baseline to 4 month FBT and sustained these improvements at 12 month maintenance. There was no evidence that latent profiles were related to percentage overweight change from baseline to FBT (p > .05) or baseline to maintenance (p > .05). There was no evidence for two-way or three-way interactions (p > .05).

CONCLUSION

Concurrent GP and EDP do not portend differential short- or long-term weight change following FBT and maintenance. Future research is warranted on the durability of weight change among youth with GP and EDP.

Eating disorder risk in adolescents with obesity

The intersection between adolescent obesity and eating disorder risk is one that requires urgent attention. This review aimed to synthesize the literature on the risk of clinical eating disorders in adolescents with obesity, discuss challenges with assessing risk, and examine implications for clinical practice and future research. Obesity and eating disorders can coexist resulting in exacerbated physical and psychological health issues. Recognized eating disorder risk factors, including body dissatisfaction, poor self-esteem, depression, and engaging in dieting behaviors, are elevated and frequently reported in adolescents with obesity, highlighting a vulnerability to the development of eating disorders. Unsupervised dieting to manage weight may exacerbate eating disorder risk, while structured and supervised weight management is likely to reduce eating disorder risk for most adolescents. However, some adolescents may present to an obesity service with an undiagnosed eating disorder or may develop an eating disorder during or following treatment. We conclude that a risk management approach, with screening or monitoring for eating disorder-related risk factors and behaviors, should be utilized to identify those at risk. Future research to identify eating disorder risk factors specific to adolescents with obesity is required to inform screening and monitoring protocols, patient care, and address current knowledge gaps.

Psychopathology and Adolescent Bariatric Surgery: A Topical Review to Support Psychologists in Assessment and Treatment Considerations

The rising rates of severe obesity among adolescents in the United States indicate a dire need for more intensive weight management strategies. While current evidence suggests that bariatric surgery is a safe and efficacious intervention for adolescents, the linkages with psychopathology before and after surgery are not well understood. Psychologists are an integral part of the interdisciplinary surgery team and play an important role in preparing youth for bariatric surgery as well as supporting adolescents post-surgery. The present manuscript reviews the literature on psychopathology in the context of adolescent bariatric surgery, discusses consideration of psychopathology as a contraindication for surgery, and provides recommendations on how psychologist members of the bariatric surgery team may balance attention to motivation and adherence to medical recommendations with assessment and treatment of psychopathology. Finally, the importance of continued research to confirm clinical consensus regarding decision-making and expansion of psychological resources within adolescent bariatric surgery programs are discussed.

Associations between weight-based teasing and disordered eating behaviors among youth

Weight-based teasing (WBT) is commonly reported among youth and is associated with disinhibited and disordered eating. Specifically, youth who experience WBT may engage in disordered eating behaviors to cope with the resultant negative affect. Therefore, we examined associations between WBT and disordered eating behaviors among youth and assessed whether negative affect mediated these relationships. Two hundred one non-treatment seeking youth (8-17y) completed questionnaires assessing WBT, disinhibited eating, depression, and anxiety. Disordered eating and loss-of-control (LOC) eating were assessed via semi-structured interview. Analyses of covariance were conducted to examine relationships between WBT and eating-related variables, and bootstrapping mediation models were used to evaluate negative affect (a composite of depressive and anxiety symptoms) as a mediator of these associations. All models were adjusted for sex, race, age, and adiposity. Among 201 participants (13.1 ± 2.8y; 54.2% female; 30.3% Black; 32.8% with overweight/obesity), WBT was associated with emotional eating, eating in the absence of hunger, and disordered eating attitudes and behaviors (ps ≤ 0.02). These associations were all mediated by negative affect. WBT was also associated with a threefold greater likelihood of reporting a recent LOC eating episode (p = .049). Among boys and girls across weight strata, WBT was associated with multiple aspects of disordered eating and these relationships were mediated by negative affect. Longitudinal studies are needed to clarify the directionality of these associations and to identify subgroups of youth that may be particularly vulnerable to WBT and its sequelae.

Self-reported symptoms of binge-eating disorder among adolescents in a community-based Danish cohort-A study of prevalence, correlates, and impact

OBJECTIVE

Binge-eating disorder (BED) was established as a diagnosis in 2013 with the DSM-5 and has been included in the ICD-11 in 2018. In adulthood, BED is prevalent and correlated with somatic and mental health problems. Less is known about BED in adolescence, although this age period could represent a window of opportunity for early intervention. This study aimed to investigate the 1-year prevalence, correlates, and impact of BED symptoms in a community sample of adolescents.

METHOD

We included 1,404 girls and 1,105 boys from the 16-years-follow-up of the Copenhagen Child Cohort study, CCC2000. The adolescents self-reported on BED symptoms, weight-status, body perception, mental health problems, and self-rated impact of food and weight-related thoughts and behaviors. Information about socio-economic factors and hospital diagnosed psychiatric disorders were obtained from national registries.

RESULTS

A total of 8.5% reported weekly overeating with loss of control (10.9% of girls, 4.8% of boys), and 2.6% (3.6% of girls, 1.2% of boys) reported symptoms consistent with BED according to the DSM-5. Regardless of sex, BED was correlated with concurrent overweight, body-dissatisfaction, low self-esteem, and mental health problems, especially emotional, but also with problems of behavior, inattention, and peer-relations, and with high self-rated impact on everyday life. Immigrant background and lower socio-economy were potential risk factors for BED in boys in this sample.

DISCUSSION

BED was prevalent and correlated with mental health problems and overall impact among adolescents in this community sample, indicating the need for clinical attention and intervention towards binge-eating disorder in the adolescent period.

Negative childhood experiences and disordered eating in adolescents in a weight management program: The role of depressive symptoms

OBJECTIVE

Stress negatively impacts adolescent weight status and eating behaviors. Previous research investigating this association has focused on traumatic events in childhood, but little is known about the impact of commonly experienced stressful life events and weight-related outcome. The aim of this cross-sectional study was to examine the association between negative life events and weight-related outcomes (i.e., weight status, disordered eating behaviors, insulin sensitivity) in a sample of treatment-seeking adolescents with overweight and obesity. A further aim of the study was to examine the potential mediating role of depression.

METHOD

Adolescents (N = 170; M age = 14.8; 62% female) presenting to an interdisciplinary weight management program completed measures related to negative life events, disordered eating patterns, and depressive symptoms prior to initiating treatment. Weight status and insulin sensitivity (using fasting glucose and fasting insulin) were objectively measured.

RESULTS

Stressful experiences during childhood were significantly related to weight status, F = 2.78, p < .05, and disordered eating, F = 5.51, p < .001, in regression analyses. Stressful life events were not related to insulin sensitivity. Depressive symptoms mediated the association between stressful experiences and disordered eating (b = 0.001, [CI = 0.0002, 0.0011]). Depressive symptoms did not mediate this association for weight status or insulin sensitivity.

DISCUSSION

Findings from the present study suggest that relatively common stressful events may be associated with development of disordered eating patterns in adolescents with overweight or obesity presenting to treatment. Providers working in weight management settings should consider assessing a range of potentially stressful life events and their potential weight-related implications.

Examination of the Interpersonal Model With Adolescent Military Dependents at High Risk for Adult Obesity

OBJECTIVE

Adolescent military dependents may be at higher risk for psychosocial stressors and disordered eating compared with civilian youths, but the mechanisms underlying these risks are unclear. Interpersonal theory proposes that difficult relationships lead to negative affect, thereby promoting emotional eating, which has been linked to and predictive of disordered eating. The interpersonal model may have particular relevance for understanding disordered eating among adolescent military dependents, given the unique stressors related to their parents' careers. This study aimed to examine the premise of the interpersonal model (that negative emotions mediate the association between multiple aspects of social functioning and emotional eating) among a cohort of adolescent military dependents.

METHODS

Military dependents (N=136; 56% female, mean±SD age=14±2 years, body mass index adjusted for age and sex [BMIz]=2.0±0.4) at risk for adult obesity and binge eating disorder, as indicated by reported loss-of-control eating and/or anxiety symptoms, were assessed prior to participation in a study of excess weight-gain prevention. Bootstrapped mediation analyses were conducted to examine depressive symptoms as a potential mediator of the relationship between social functioning and emotional eating. Analyses were adjusted for age, sex, race-ethnicity, BMIz, and presence of reported loss-of-control eating and anxiety.

RESULTS

Depressive symptoms were a significant mediator of the relationship between multiple domains of social functioning, including loneliness, social adjustment related to family and friends, attachment to father and peers, and emotional eating (p<0.05).

CONCLUSIONS

The interpersonal model may contribute to our understanding of excess weight gain and binge eating disorder among adolescent military dependents. Prospective data are needed to determine the utility of interpersonal theory in predicting treatment response and outcomes among this population.

Assessment of loss-of-control eating in healthy youth by interview and questionnaire

OBJECTIVE

The aim of this study is to evaluate two questionnaires, an updated youth version of the questionnaire on eating and weight patterns (Questionnaire on Eating and Weight Patterns-5 Children/Adolescent [QEWP-C-5]) and the Loss-of-Control (LOC) Eating Disorder Questionnaire (LOC-ED-Q), against the Eating Disorder Examination (EDE) interview to assess the presence of LOC-eating among youth.

METHOD

Two-hundred and eighteen youths (12.8 ± 2.7 years) completed the QEWP-C-5, LOC-ED-Q, and EDE, depressive and anxiety questionnaires, and adiposity assessment. Sensitivity, specificity, positive-predictive value, negative-predictive value, and diagnostic accuracy were calculated; Cochran's Q and McNemar's tests were used to compare measures. Receiver operating characteristic area under the curve (AUC) analyses were performed. Mood and adiposity based on LOC-eating presence and absence based on each measure were examined.

RESULTS

The QEWP-C-5 and LOC-ED-Q demonstrated poor sensitivity (33%; 30%) and high specificity (95%; 96%) compared with the EDE. The AUCs suggested neither the QEWP-C-5 (0.64) nor the LOC-ED-Q (0.62) demonstrated acceptable diagnostic accuracy. Comparing distributions of LOC-eating presence between assessments, the QEWP-C-5 and EDE did not differ significantly (p = .10), while the LOC-ED-Q and EDE had significantly different distributions (p = .03). LOC-eating presence was associated with higher depressive and anxiety symptoms across all measures (ps < .02). Greater adiposity (ps < .02) was associated with LOC-eating presence on the EDE and LOC-ED-Q, and higher BMI z-score (p = .02) on the LOC-ED-Q.

DISCUSSION

Neither the QEWP-C-5 nor the LOC-ED-Q was sensitive for identifying LOC-eating presence as determined by the EDE, although both were associated with greater mood symptoms. Research is needed to improve self-report questionnaires to better screen for LOC-eating presence among pediatric populations.

Associations between latent trait negative affect and patterns of food-intake among girls with loss-of-control eating

OBJECTIVE

Momentary negative affect (NA) has been shown to predict eating patterns in the laboratory, yet, more stable mood states have not been studied in relation to eating patterns in the laboratory among youth at high risk for binge-eating disorder and obesity.

METHOD

One-hundred-eight adolescent girls (14.5 ± 1.7 years) with BMI between the 75th-97th percentile who reported loss-of-control (LOC)-eating completed measures of trait anxiety and depressive symptoms. Food-intake patterns were measured from a laboratory test meal (9,385 kcal). Latent factor analysis of depressive symptoms and trait anxiety was used to compute latent trait NA. Multivariate general linear models predicted total energy, snacks, and macronutrient intake from trait NA, adjusting for age, race, height, lean-mass, and percentage fat-mass.

RESULTS

Trait NA was significantly positively related to total energy-intake, and, specifically, snacks, sweet snacks, and percentage sweet fats (ps ≤ .03), and negatively related to percentage protein consumed (p = .04).

DISCUSSION

Expanding on affect theory, trait NA may relate to palatable food-intake among girls with LOC-eating. Further data are needed to determine whether those with LOC-eating and trait NA are at heightened risk for the development of binge-eating disorder and obesity.

Protocol for a pilot randomized controlled feasibility study of brief interpersonal psychotherapy for addressing social-emotional needs and preventing excess gestational weight gain in adolescents

BACKGROUND

Excess gestational weight gain (GWG) in pregnant adolescents is a major public health concern. Excess GWG increases risk of pregnancy complications as well as postpartum and offspring obesity and cardiometabolic disease. Prevention interventions for pregnant adults that target lifestyle modification (i.e., healthy eating/physical activity) show insufficient effectiveness. Pregnant adolescents have distinct social-emotional needs, which may contribute to excess GWG. From an interpersonal theoretical framework, conflict and low social support increase negative emotions, which in turn promote excess GWG through mechanisms such as overeating and physical inactivity.

METHODS

The current manuscript describes the design of a pilot randomized controlled feasibility trial of adolescent interpersonal psychotherapy (IPT) to address social-emotional needs and prevent excess GWG. Up to 50 pregnant, healthy adolescents 13-19y, 12-18 weeks gestation are recruited from an interdisciplinary adolescent maternity hospital clinic and randomized to IPT + usual care or usual care alone. IPT involves 6 individual 60-minute sessions delivered by a trained behavioral health clinician during 12-30 weeks gestation. Sessions include relationship psychoeducation, emotion identification and expression, and teaching/role-playing communication skills. Between sessions, adolescents are instructed to complete a daily journal and to have conversations to work on relationship goals. Outcomes are assessed at baseline, mid-program, post-program, and 3-months postpartum. Primary outcomes are feasibility and acceptability based upon rate of recruitment, session attendance, program acceptability ratings, and follow-up retention. Secondary outcomes are perinatal social functioning, stress, depression, and eating behaviors assessed with validated surveys and interviews; perinatal physical activity and sleep measured via accelerometer; GWG from measured weights; and at 3-months postpartum only, maternal adiposity by dual energy x-ray absorptiometry, maternal insulin sensitivity derived from 2-hour oral glucose tolerance testing, and infant adiposity by air displacement plethysmography.

DISCUSSION

This pilot trial will address a key gap in extant understanding of excess GWG prevention for a high-risk population of adolescents. If feasible and acceptable, brief psychotherapy to address social-emotional needs should be tested for its effectiveness to address excess GWG and postpartum maternal/infant health. If effective, such an approach has potential to interrupt an adverse, intergenerational cycle of social-emotional distress, obesity, and cardiometabolic disease among young mothers and their offspring.

Pediatric Loss-of-Control Eating and Anxiety in Relation to Components of Metabolic Syndrome

Objective

Pediatric loss-of-control (LOC) eating is associated with, and predictive of, gains in adiposity and adverse metabolic outcomes. In addition, some preliminary data suggest that anxiety may exacerbate the relationship of LOC eating with weight and metabolic syndrome (MetS)-related measures. We therefore examined whether anxiety moderated the relationship between LOC eating and body mass index z (BMIz), adiposity, and MetS-related measures in youth.

Methods

A convenience sample of non-treatment-seeking boys and girls of varying weight strata were interviewed to determine the presence of LOC eating and completed a questionnaire assessing trait anxiety. BMIz and MetS-related measures (blood pressure, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, glucose, and insulin) were measured after an overnight fast. Adiposity was assessed by air displacement plethysmography or dual-energy x-ray absorptiometry. Analyses adjusted for age, sex, race, height, fat mass, and depressive symptoms, as appropriate.

Results

In all, 379 youths (13.0 ± 2.8 years; 53% female; BMIz = 0.8 ± 1.1; 22% with LOC eating) were studied. Anxiety was not significantly related to BMIz, adiposity, or MetS-related measures. However, anxiety and LOC eating interacted such that only among youth with LOC eating, anxiety was positively associated with fasting insulin (p = .02) and insulin resistance (p = .01). The interaction of anxiety and LOC eating was not significantly related to BMIz, adiposity, or any other MetS-related measure (ps = ns).

Conclusions

Only among non-treatment-seeking youth with LOC eating, anxiety may be associated with increased insulin secretion and insulin resistance. Longitudinal studies are required to confirm these findings and explore mechanisms for these relationships.

A developmental framework of binge-eating disorder based on pediatric loss of control eating

Although binge-eating disorder may manifest in childhood, a significantly larger proportion of youth report episodes involving a loss of control while eating, the hallmark feature of binge eating that predicts excess weight gain and obesity. Adults with binge-eating disorder often report that symptoms emerged during childhood or adolescence, suggesting that a developmental perspective of binge eating may be warranted. Thus, loss of control eating may be a marker of prodromal binge-eating disorder among certain susceptible youth. The present article offers a broad developmental framework of binge-eating disorder and proposes areas of future research to determine which youths with loss of control eating are at risk for persistent and exacerbated behavior that may develop into binge-eating disorder and adult obesity. To this end, this article provides an overview of loss of control eating in childhood and adolescence, including its characterization, etiology, and clinical significance, with a particular focus on associations with metabolic risk, weight gain, and obesity. A conceptual model is proposed to further elucidate the mechanisms that may play a role in determining which youths with loss of control are at greatest risk for binge-eating disorder and obesity. Ways in which treatments for adult binge-eating disorder may inform approaches to reduce loss of control eating and prevent excess weight gain in youth are discussed.

Associations between Family Weight-Based Teasing, Eating Pathology, and Psychosocial Functioning among Adolescent Military Dependents

Weight-based teasing (WBT) by family members is commonly reported among youth and is associated with eating and mood-related psychopathology. Military dependents may be particularly vulnerable to family WBT and its sequelae due to factors associated with their parents' careers, such as weight and fitness standards and an emphasis on maintaining one's military appearance; however, no studies to date have examined family WBT and its associations within this population. Therefore, adolescent military dependents at-risk for adult obesity and binge-eating disorder were studied prior to entry in a weight gain prevention trial. Youth completed items from the Weight-Based Victimization Scale (to assess WBT by parents and/or siblings) and measures of psychosocial functioning, including the Beck Depression Inventory-II, The Rosenberg Self-Esteem Scale, and the Social Adjustment Scale. Eating pathology was assessed via the Eating Disorder Examination interview, and height and fasting weight were measured to calculate BMIz. Analyses of covariance, adjusting for relevant covariates including BMIz, were conducted to assess relationships between family WBT, eating pathology, and psychosocial functioning. Participants were 128 adolescent military dependents (mean age: 14.35 years old, 54% female, 42% non-Hispanic White, mean BMIz: 1.95). Nearly half the sample (47.7%) reported family WBT. Adjusting for covariates, including BMIz, family WBT was associated with greater eating pathology, poorer social functioning and self-esteem, and more depressive symptoms (ps ≤ 0.02). Among military dependents with overweight and obesity, family WBT is prevalent and may be linked with eating pathology and impaired psychosocial functioning; prospective research is needed to elucidate the temporal nature of these associations.

Relationships of Trait Anxiety and Loss of Control Eating with Serum Leptin Concentrations among Youth

Loss of control (LOC) eating in youth is associated with elevated fasting serum leptin, even after accounting for adiposity. Anxiety is closely linked to, and may exacerbate, LOC eating. Yet, it remains unclear how anxiety relates to leptin, or if the relationship is moderated by the presence of LOC eating. We examined whether self-reported trait anxiety interacted with LOC eating in relation to leptin in a convenience sample of youths (n = 592; 13.1 ± 2.7 years; body mass index z-score (BMIz) = 0.9 ± 1.1; 61.8% girls; 53.5% non-Hispanic White; 36.6% with LOC eating). LOC eating was assessed by interview. Leptin was measured after an overnight fast. Exploratory analyses were conducted to examine anxiety and LOC eating in relation to laboratory intake patterns in three sub-samples. In a generalized linear model adjusting for relevant covariates, anxiety significantly interacted with LOC eating in relation to leptin (p = 0.02), such that greater trait anxiety related to higher concentrations of leptin only among youth with LOC eating. Trait anxiety was not significantly related to fasting serum leptin independently in a generalized linear model adjusting for age, race, height, sex, study type, and fat mass (kg). Exploratory mechanistic analyses of food intake patterns did not identify consistent results for participants with both anxiety and LOC eating. Among youth with LOC eating, anxiety may be associated with higher serum leptin. Prospective data are required to elucidate the directionality and mechanisms of these relationships.

Factors associated with depression and anxiety symptoms among children seeking treatment for obesity: A social-ecological approach

BACKGROUND

Children with overweight/obesity are more likely to exhibit symptoms of depression and anxiety than are their peers without overweight/obesity; however, the rates and correlates of depression and anxiety symptoms among children seeking obesity treatment remain unclear.

OBJECTIVES

Examine the prevalence and associated factors of depression and anxiety symptoms among treatment-seeking children with overweight/obesity.

METHODS

Children 7 to 11 years old (N = 241) and their parents completed assessments before beginning family-based behavioral weight-loss treatment. Disorder-specific self-report questionnaires assessed child depression and anxiety. The social-ecological model served as a framework for examining factors associated with depression and anxiety symptoms.

RESULTS

Among our sample, 39.8% (96/241) met clinical cutoffs for depression and/or anxiety symptomatology. Specifically, of these 96, 48 met criteria for both depression and anxiety, 24 for depression only, and 24 for anxiety only. Child eating disorder pathology, parents' use of psychological control (ie, a parenting style characterized by emotional manipulation), and lower child subjective social status were significantly associated with greater child depression symptomatology. Child eating disorder pathology and parent psychological control were significantly associated with greater child anxiety symptomatology.

CONCLUSION

Nearly 40% of children exhibited psychopathology symptoms, and a variety of correlates were found. Thus, pediatric weight-loss providers may consider screening for and addressing mental health concerns (and associated factors) prior to and during treatment.

The association between alexithymia and eating behavior in children and adolescents

OBJECTIVE

Alexithymia, or the difficulty identifying or describing one's own emotions, may be a risk factor for dysregulated eating and excess weight gain. However, the relationships between alexithymia and eating behaviors in community samples of non-clinical youth have not been well-characterized. We hypothesized that alexithymia would be positively associated with disordered and disinhibited eating in a community-based sample of boys and girls without an eating disorder.

METHOD

Two hundred children (8-17 years old) across the weight spectrum completed an interview to assess loss of control (LOC) eating and eating-related psychopathology, a laboratory test meal designed to induce disinhibited eating, and questionnaires to assess alexithymia, eating in the absence of hunger, and emotional eating. Linear and logistic regressions were conducted to examine the relationship between alexithymia and eating variables, with age, sex, race, and fat mass as covariates. Test meal analyses also adjusted for lean mass. Given the overlap between alexithymia and depression, all models were repeated with depressive symptoms as an additional covariate.

RESULTS

Alexithymia was associated with an increased likelihood of reporting LOC eating (p < .05). Moreover, alexithymia was positively associated with disordered eating attitudes, emotional eating, and eating in the absence of hunger (ps < .05). Greater alexithymia was associated with more carbohydrate and less fat intake at the test meal (ps < .05). After adjusting for depressive symptoms, alexithymia remained associated with eating in the absence of hunger and carbohydrate and fat intake (ps < .05).

DISCUSSION

In healthy children, alexithymia is associated with some facets of eating behavior and food intake. If supported prospectively, these preliminary findings suggest alexithymia may be a modifiable risk factor to reduce disordered eating and excess weight gain in youth.

Bariatric Surgery in Children: Indications, Types, and Outcomes

PURPOSE OF REVIEW

The purpose of this review is to discuss the current state of surgical intervention for obesity in children and adolescents. Specifically, this review will discuss the different types of metabolic and bariatric surgery (MBS) procedures, guidelines for patient selection, and recent findings regarding surgical outcomes and complications.

RECENT FINDINGS

MBS is safe in adolescents and has also demonstrated sustainable long term weight loss and improvement in obesity-associated comorbidities. A recent prospective multi-institutional trial demonstrated BMI reductions of 3.8 kg/m² (8%) to 15.1 kg/m² (28%) after 3 years among adolescents undergoing the three most common MBS procedures. Moreover, MBS is associated with remission of type 2 diabetes, prediabetes, hypertension, dyslipidemia, and abnormal kidney function in 65-95% of patients in the study. Childhood and adolescent obesity is a continuing problem that has not been adequately addressed by the medical community. MBS is currently the most successful strategy for significant and sustained weight loss and improvement of associated comorbidities. This review focuses on the different types of MBS, the selection and preparation of patients for surgery, and the expected outcomes and common complications.

Sex differences in eating related behaviors and psychopathology among adolescent military dependents at risk for adult obesity and eating disorders

Stressors unique to military families may place dependents of military service members of both sexes at high-risk for disordered-eating. Yet, there are no data examining sex-related differences in eating pathology and distress among this population. Therefore, we examined disordered-eating attitudes and associated psychosocial characteristics in adolescent military dependents at high-risk for both eating disorders and adult obesity (i.e., BMI ≥ 85th percentile and elevated anxiety symptoms and/or loss-of-control eating). One-hundred-twenty-five (55.2% female) adolescent (12-17 y) military dependents were studied prior to entry in an eating disorder and obesity prevention trial. Youth were administered the Eating Disorder Examination interview to determine disordered-eating attitudes, and completed questionnaires to assess self-esteem, social functioning, and depression. Girls and boys did not differ in BMIz (p = .66) or race/ethnicity (p = .997/p = .55). Adjusting for relevant covariates, girls and boys did not differ significantly with regard to disordered-eating global scores (p = .38), self-esteem (p = .23), or social functioning (p = .19). By contrast, girls reported significantly more symptoms of depression (p = .001). Adolescent male and female dependents at high-risk for eating disorders and adult obesity reported comparable levels of eating-related and psychosocial stress. Data are needed to elucidate how adolescent military dependents respond to intervention and whether sex moderates outcome.

Pediatric Obesity and Eating Disorders Symptoms: The Role of the Multidisciplinary Treatment. A Systematic Review

The prevalence of obesity in children/adolescents has increased worldwide during the past 30 years, becoming a significant public health concern; prevention, and management of pediatric obesity onset is one of the most critical public health goals for both industrialized and developing countries. Pediatric obesity has been identified as a risk factor for various psychopathologies, including eating disorders (ED). Although it has been demonstrated that a comprehensive multidisciplinary treatment (MT), with small steps and practical approaches to lifestyle change, can be an effective treatment for children and adolescents with obesity, to the best of our knowledge, this is the first systematic review investigating the effect of MT on the development, progression or decrease of ED symptoms (EDS) in this target population. PubMed and Web of Science databases were searched (last search on 18 February 2019) according to a predetermined search strategy, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines and Statement. Original studies published in English examining the effect of MT on pediatric overweight/obesity, paying particularly attention at the development of EDS, were eligible for inclusion. Seven hundred and forty-four records have been identified; nine articles with study quality ranging from weak to moderate have been included. MTs were heterogeneous in nature including length, number, frequency and type of sessions, parent-involvement and use of technology, besides several psychometric questionnaires were used to screen for EDS, since there are no standardized criteria. In 3 studies there was a significant decrease in external and emotional eating and in four studies a significant increase in restraint eating post MT. Two studies found a significant decrease of binge eating symptoms and other two studies showed an improvement of self-perception, weight, and shape concern. A statistical significant decrease in BMI, BMIz, BMISDS, and adjusted BMI was observed after all MTs, except one. A narrative summary of the evidences reported highlighted the positive impact of MT on the EDS. Moreover, since weight loss post MTs was not necessarily related to EDS, clinicians should also look for the presence of EDS and treat them accordingly.

An examination of the associations between pediatric loss of control eating, anxiety, and body composition in children and adolescents

BACKGROUND

Data on the link between anxiety and body composition in youth are mixed. Yet, anxiety and disordered eating are highly correlated. One pathway between anxiety and excess body weight and fat mass may be through loss of control (LOC) eating. We examined whether LOC eating mediated the relationship between anxiety and body composition in youth with and without overweight.

METHOD

Non-treatment-seeking youth (8-17 years) participated in studies examining weight and eating behaviors. Anxiety (child- and parent-report of child) and LOC eating were assessed by self-report questionnaires and interviews, respectively. Fat mass was assessed by dual-energy x-ray absorptiometry or air displacement plethysmography. Cross-sectional mediation models with bias-corrected bootstrap confidence intervals (CI) were conducted.

RESULTS

257 youth (12.91 ± 2.76 years; 52.5% female; BMI-z 0.93 ± 1.07) were studied. There was a significant indirect path between child-reported anxiety and both BMI-z (ab = .005, SE = 0.003, 95% CI = 0.001-0.01) and body fat mass (ab = 0.001, SE = 0.001, 95% CI ≤0.001-0.003) through the number of LOC episodes in the past month. No significant indirect paths through the number of LOC episodes was observed for parent-report of child anxiety on BMI-z (ab = 0.004, SE = 0.01, 95% CI = -0.01-0.03) or body fat mass (ab = 0.001, SE = 0.002, 95% CI = -0.002-0.01). No direct paths were observed between anxiety and body composition regardless of the informant.

DISCUSSION

LOC eating appears to mediate the relationship of child-reported anxiety with body composition in non-treatment seeking boys and girls. Prospective data are needed to determine if anxiety promotes LOC eating that results in increased risk for excess body weight and fat gain.

Men who engage in both subjective and objective binge eating have the highest psychological and medical comorbidities

Data suggest that assessing for the presence of loss of control (LOC) while eating is more useful in identifying risk for excess weight gain and psychosocial comorbidities than focusing on the amount of food consumed during episodes of perceived overeating. Yet, most of this research has included children and women. The current study examined whether perceived overeating patterns with and without LOC were uniquely associated with eating- and weight-related comorbidities in a community sample of young men. Participants (N = 1114; 18-30 y) completed a brief online survey assessing body mass index (BMI); perceived overeating habits, including overeating without LOC (OEs), and subjective (SBEs) and objective binge eating episodes (OBEs); weight-related medical comorbidities; and disordered eating pathology. After adjusting for BMI and race/ethnicity, men who reported engaging in both OBE(s) and SBE(s) were the most likely to have a weight-related medical comorbidity, and reported the highest levels of dietary restraint, concerns about body fat, and excessive exercise pathology. Group differences remained even after adjusting for frequency of disordered eating episodes, a common indicator of severity of comorbid pathology. The current study's findings suggest that young men who engage in both OBE(s) and SBE(s) may be at the highest risk for chronic disease and psychological concerns, although additional studies with prospective data are necessary to confirm this hypothesis.

Diagnosis, treatment and prevention of pediatric obesity: consensus position statement of the Italian Society for Pediatric Endocrinology and Diabetology and the Italian Society of Pediatrics

The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase.

Remission of loss of control eating and changes in components of the metabolic syndrome

OBJECTIVE

Pediatric loss of control (LOC) eating prospectively predicts the worsening of metabolic syndrome components. However, it is unknown if remission of LOC eating is associated with improvements in metabolic health. Therefore, we conducted a secondary analysis of a trial that enrolled adolescent girls with LOC eating, examining whether LOC remission (vs. persistence) at end-of-treatment was associated with changes in metabolic syndrome components at 6-month follow-up.

METHOD

One hundred three adolescent girls (age 14.5 ± 1.7 years; BMI-z 1.5 ± 0.3; 56.3% non-Hispanic White, 24.3% non-Hispanic Black) with elevated weight (75th-97th BMI %ile) and reported LOC eating were assessed for metabolic syndrome components at baseline and again six months following the interventions. The main effects of LOC status at end-of-treatment (persistence vs. remission) on metabolic syndrome components (waist circumference, lipids, glucose, and blood pressure) at 6-month follow-up were examined, adjusting for baseline age, depressive symptoms, LOC frequency, fat mass, and height, as well as race, change in height, change in fat mass, and the baseline value of each respective component.

RESULTS

Youth with LOC remission at end-of-treatment had lower glucose (83.9 ± 6.4 vs. 86.5 ± 5.8 mg/dL; p = .02), higher high-density lipoprotein cholesterol (50.3 ± 11.8 vs. 44.8 ± 11.9 mg/dL; p = .01), and lower triglycerides (84.4 ± 46.2 vs. 96.9 ± 53.7 mg/dL; p = .02) at 6-month follow-up when compared with youth with persistent LOC, despite no baseline differences in these components. No other component significantly differed by LOC eating status (ps > .05).

DISCUSSION

Reducing LOC eating in adolescent girls may have a beneficial impact on some components of the metabolic syndrome.

Attention-Deficit/Hyperactivity Disorder Symptoms Are Associated with Overeating with and without Loss of Control in Youth with Overweight/Obesity

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.

Patterns of Eating Disorder Pathology are Associated with Weight Change in Family-Based Behavioral Obesity Treatment

OBJECTIVE

Children with overweight or obesity have elevated eating disorder (ED) pathology, which may increase their risk for clinical EDs. The current study identified patterns of ED pathology in children with overweight or obesity entering family-based behavioral weight loss treatment (FBT) and examined whether children with distinct patterns differed in their ED pathology and BMI z score (zBMI) change across FBT.

METHODS

Before participating in a 16-session FBT, children (N = 241) completed surveys or interviews assessing ED pathology (emotional eating, shape/weight/eating concerns, restraint, and loss of control [LOC]). Shape and weight concerns (SWC) and LOC were also assessed post treatment. Child height and weight were measured at baseline and post treatment. Latent class analysis identified patterns of ED pathology. Repeated-measures ANOVA examined changes in zBMI and ED pathology.

RESULTS

Four patterns of ED pathology were identified: low ED pathology, SWC, only loss of control, and high ED pathology. SWC decreased across treatment, with the highest decreases in patterns characterized by high SWC. All groups experienced significant decreases in zBMI; however, children with the highest ED pathology did not achieve clinically significant weight loss.

CONCLUSIONS

ED pathology decreased after FBT, decreasing ED risk. While all children achieved zBMI reductions, further research is needed to enhance outcomes for children with high ED pathology.

Socioenvironmental, Personal, and Behavioral Correlates of Severe Obesity among an Ethnically/Racially Diverse Sample of US Adolescents

BACKGROUND

Severe obesity among adolescents, also known as class 2 and 3 obesity, is increasing in prevalence, yet, little is known about adolescents with severe obesity. The objective of this study was to identify the socioenvironmental, personal, and behavioral correlates of severe obesity among an ethnically/racially diverse sample of US adolescents.

METHODS

A cross-sectional analysis of data from participants in the EAT 2010 study (n = 2706) was conducted. Adolescents completed in-class surveys, and height and weight were measured. Severe obesity was defined as a BMI ≥120% of the 95th percentile or ≥35 kg/m²; class 1 obesity as a BMI ≥95th percentile but below severe obesity cut points, overweight as a BMI <95th percentile but ≥85th percentile, and normal weight as a BMI <85th but >5th percentile. General linear models were used to identify differences between adolescents by weight status, adjusted for covariates.

RESULTS

Nine percent of adolescents had severe obesity. Compared with peers of other weight statuses, a greater proportion of adolescents with severe obesity reported parental encouragement to diet and peer weight teasing. Adolescents with severe obesity also reported lower self-esteem and body satisfaction. Binge eating was three times as prevalent among adolescents with severe obesity compared with peers of normal weight and twice as prevalent as among peers with class 1 obesity.

CONCLUSIONS

Adolescents with severe obesity report several unique socioenvironmental, personal, and behavioral concerns that may diminish quality of life and may predict increased weight gain over time.

Different Facets of Body Image Disturbance in Binge Eating Disorder: A Review

The goal of the present review is to give an overview of the current findings on various facets of body image disturbance in Binge Eating Disorder such as body dissatisfaction, overconcern with weight and shape, body-related checking and avoidance behavior, misperception of body size, and body-related cognitive bias. In addition, treatments for a disturbed body image in BED and evidence of body image disturbance in youth with binge eating are reviewed. The results show that a disturbed body image in BED is present in the form of overconcern with weight and shape. Furthermore, there are hints that body dissatisfaction, as well as body-related checking and avoidance behavior, are also impaired. Research concerning misperception of body size in BED has been neglected so far, but first findings show that individuals with BED rate their own body shape rather accurately. Furthermore, there are first hints that body-related cognitive biases are present in individuals with BED. Moreover, in children and adolescents, there are first hints that body dissatisfaction, as well as shape and weight concerns, seem to be associated with loss of control and binge eating. Treatments aimed directly at the convertibility of a disturbed body image in BED have revealed encouraging outcomes. In conclusion, body image disturbance seems to occur in BED, and first studies show that it can be treated effectively.

Prospective Relations between Overeating, Loss of Control Eating, Binge Eating, and Depressive Symptoms in a School-Based Sample of Adolescents

A sample of 353 community adolescents (grades 9 to 12, 57.6 % female) participated in a 2-wave longitudinal study of eating behaviors (overeating, loss of control eating [LOC], and binge eating) and depression. The study addresses 4 hypotheses. (1) The prospective relations between eating behaviors and depressive symptoms will be reciprocal, with each predicting the other over time. (2) These relations will be stronger for girls than for boys. (3) These relations will be stronger for adolescents with high (not low) body mass index (BMI). (4) LOC will show incremental predictive utility in relation to depressive symptoms over and above overeating. Evidence supported reciprocal relations between binge eating and depressive symptoms and between overeating and depressive symptoms, but not between LOC and depressive symptoms. Sex and BMI did not substantially moderate these relations. Taken separately, overeating but not LOC predicted depressive symptoms. Taken together, neither predictor was significant controlling for the other. Results raise questions about the importance of LOC alone in predicting depressive symptoms in adolescence.
