Associated features of pediatric loss-of-control eating severity during a laboratory-based feeding paradigm. Eat Behav 2023; 50:101790. [PMID: 37536224 PMCID: PMC10529390 DOI: 10.1016/j.eatbeh.2023.101790] [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: 03/28/2023] [Revised: 07/24/2023] [Accepted: 07/25/2023] [Indexed: 08/05/2023]
Abstract
Laboratory-based loss-of-control eating (LOC-eating; i.e., feeling like one cannot stop eating) paradigms have provided inconsistent evidence that the features of pediatric LOC-eating are consistent with those of DSM-5-TR binge-eating episodes. Thus, this study investigated whether recent LOC-eating (in the prior month) and/or greater LOC-eating severity during a meal are positively associated with faster eating rate, energy intake when adjusting for hunger, post-meal stomachache and sickness (a proxy for eating until uncomfortably full), depression, and guilt. Recent LOC-eating was assessed via interview. Participants were presented with a buffet-type meal and instructed to "Let yourself go and eat as much as you want." Immediately following, youth reported on their experience of LOC-eating during the meal (LOC-eating severity). Eating rate (kcal/min) was computed by dividing total energy intake by the duration of the meal. Prior to and following the meal, youth reported hunger, sickness, and stomachache via sliding Visual Analog Scales, depression via the Brunel Mood Scale and guilt via the PANAS-X. Three-hundred-ten youth participated (61.2 % Female; 46.3 % non-Hispanic White, 12.96 ± 2.72 y). Recent LOC-eating was not significantly associated with any DSM-5-TR binge-eating feature during the laboratory meal (ps = 0.07-0.85). However, LOC-eating severity during the meal was positively associated with eating rate, eating adjusted for hunger, post-meal sickness and stomachache, and guilt (ps < 0.045). LOC-eating severity during a laboratory-based feeding paradigm meal, but not recent LOC-eating, was associated with several features of DSM-5-TR binge-eating episodes. Future studies should assess multiple components of LOC-eating to further characterize the phenomenology of pediatric LOC-eating.

Abstract
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.

Factors Associated with Eating in the Absence of Hunger among Children and Adolescents: A Systematic Review. Nutrients 2022; 14:nu14224715. [PMID: 36432407 PMCID: PMC9699171 DOI: 10.3390/nu14224715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 10/31/2022] [Accepted: 11/03/2022] [Indexed: 11/10/2022] Open
Abstract
Eating in the absence of hunger (EAH) has been extensively studied over the past two decades and has been associated with excess body weight and the development of obesity. However, determinants of EAH remain uncertain. This systematic review aims to identify individual, familial, and environmental factors associated with EAH among children and adolescents. We included studies with a measure of EAH in participants aged 3-17 years old and including ≥1 factor associated with EAH. Our search identified 1494 articles. Of these, we included 81 studies: 53 cross-sectional, 19 longitudinal and nine intervention studies. In childhood (≤12 years old), EAH increases with age, it is greater in boys compared to girls, and it is positively associated with adiposity. Moreover, EAH development seems to be influenced by genetics. In adolescence, the number of studies is limited; yet, studies show that EAH slightly increases or remains stable with age, is not clearly different between sexes, and findings for overweight or obesity are less consistent across studies in adolescence. For familial factors, parental restrictive feeding practices are positively associated with EAH during childhood, mostly for girls. Studies assessing environmental factors are lacking and robust longitudinal studies spanning from early childhood to adolescence are needed.

Abstract
Binge eating is a transdiagnostic eating disorder symptom that can occur in patients with anorexia nervosa (AN), persisting after weight restoration, and impeding their recovery. However, little is known about the biological predictors of binge eating after AN weight restoration. The goals of this exploratory study of 73 females with AN were: (1) to examine changes in cortisol, the adrenocorticotropic hormone, norepinephrine, ghrelin (total and active), and leptin levels across the admission, discharge, and 3 months post-discharge from the inpatient AN weight restoration; and (2) to determine whether the target hormones were associated with objective or subjective binge eating (OBE or SBE). The participants completed the self-reported Eating Disorder Examination Questionnaire, Beck Anxiety Inventory, and Beck Depression Inventory-II, and provided fasting whole blood samples for hormone assays. The results showed significant changes in body mass index (BMI), cortisol, total ghrelin, and leptin levels over the three time points. The cortisol levels at admission and discharge were significantly associated with the number of SBE episodes at 3 months post-discharge. Findings suggest the need to replicate and confirm the role of cortisol in predicting the emergence of SBE and uncover the mechanisms underlying SBE and cortisol to prevent SBE and its negative consequences.

Abstract
OBJECTIVE Loss of control over eating (LOC) is common among adolescents and is associated with negative developmental outcomes. Low self-regulation, and specifically low inhibitory control, is increasingly emphasized as an underlying factor in LOC. However, the specific context in which these capacities fail remains unclear. The affect regulation model proposes that negative affect may trigger LOC; however, research has mostly assessed trait negative affect using questionnaires, whereas measuring state negative affect is needed to determine its triggering role. Therefore, this study examined the interaction between inhibitory control and state negative affect in predicting LOC among adolescents using an experimental mood-induction design. METHOD Participants were 50 adolescents (10-18 years; 76% girls) from the general community. Participants first reported on their self-regulatory and inhibitory control capacities. They were then assigned to a sad or neutral mood-induction (using a film clip), followed by a multi-item food buffet from which they could eat as much as they liked. Finally, participants reported on their experience of loss of control while eating. RESULTS Inhibitory control (but not self-regulation in general) interacted with the mood-induction to predict LOC. Adolescents with low inhibitory control experienced significantly more LOC, but only in the sad mood condition. DISCUSSION The experience of negative affect appears to be an important trigger for LOC in adolescents with low inhibitory control. With a view to prevention and early intervention of LOC, inhibitory control training may be most effective in contexts where adolescents experience high levels of negative affect.

Abstract
PURPOSE OF REVIEW This review summarizes findings on pediatric loss-of-control (LOC) eating and obesity published since 2013 in relation to physiological, socioenvironmental, and psychological factors. RECENT FINDINGS LOC eating and obesity are highly comorbid in youth. Genetic and physiological risk factors are associated with the development of LOC eating. Adverse physiological outcomes of LOC eating include increased risk for overweight and obesity and greater dysfunction in components of metabolic syndrome. Socioenvironmental, psychological, and behavioral factors, such as weight-based teasing, dieting, negative affect, emotion dysregulation, and aspects of cognitive functioning, are consistently related to LOC eating in youth, independent of weight. Prospectively, LOC eating may predict the onset of anxiety disorders, depression, and more severe eating psychopathology later in life. Updates on interventions and future directions are discussed. LOC eating may be a key symptom to target adverse physiological and psychological outcomes; however, treatments are limited and require further examination.

Abstract
Besides physical consequences, obesity has negative psychological effects, thereby lowering human life quality. Major psychological consequences of this disorder includes depression, impaired body image, low self-esteem, eating disorders, stress and poor quality of life, which are correlated with age and gender. Physical interventions, mainly diet control and energy balance, have been widely applied to treat obesity; and some psychological interventions including behavioral therapy, cognitive behavioral therapy and hypnotherapy have showed some effects on obesity treatment. Other psychological therapies, such as relaxation and psychodynamic therapies, are paid less attention. This review aims to update scientific evidence regarding the mental consequences and psychological interventions for obesity.

Abstract
OBJECTIVE Low inhibitory control is linked with weight gain among youth. Inhibitory problems are associated with disruption to the hypothalamic-pituitary-adrenal axis cortisol response. Increased cortisol predicts appetite and weight gain (though may be gender specific). This study hypothesized that cortisol reactivity explains the association between inhibition and weight gain while considering the moderating factors of early stressors to the hypothalamic-pituitary-adrenal axis (e.g. prenatal-drug exposure) and gender. METHODS Adolescents with prenatal-drug exposure (n = 76) and non-exposed comparison adolescents (NE; n = 61) completed the Conner's Continuous Performance Test and provided salivary cortisol samples. BMI z-score were measured at the initial and 12-month follow-up evaluations. A bootstrapped moderated mediation analysis was conducted to test for conditional indirect effects of cortisol reactivity. RESULTS Lower inhibition was associated with increased cortisol reactivity among youth who were NE, and increased cortisol reactivity was associated with weight gain among girls. Cortisol reactivity mediated the relation between inhibition and BMI z-score change for the girls in the group who was NE. CONCLUSION Increased cortisol reactivity may play a mechanistic role in predicting weight gain among non-prenatally drug-exposed girls. Cortisol reactivity may be a biomarker for targeted interventions to improve biological regulation and ultimately health risk among girls.

Abstract
BACKGROUND Restrictive feeding is implicated in pediatric obesity, and caregivers increase controlling feeding practices on the basis of higher child weight status. However, few studies have examined how child genetic and parenting characteristics together impact restrictive feeding. OBJECTIVES We examined whether child body mass index (BMI) status predicts caregiver use of restrictive feeding and if this association is moderated by (i) caregiver strategies to manage their children's distress and (ii) child variations in the catechol-O-methyltransferase (COMT) gene (Val158 Met, rs4680). METHODS Participants included 126 Caucasian children (50% girls) and their caregivers who were participating in a larger study in the USA. Caregivers reported on their feeding practices and responses to child distress when children were 2.5-3.5 years of age. Child anthropometric measurements were also obtained. Restrictive feeding was assessed again 1-1.5 years later. Genomic DNA was obtained from saliva samples, and COMT-rs4680 was genotyped using TaqMan® methodology. RESULTS Child BMI percentile predicted subsequent caregiver restrictive feeding for children who were Met/Met and who had caregivers reporting higher use of negative responses to child distress. For Val carriers, BMI percentile predicted restrictive feeding when caregivers were below the mean on these responses. CONCLUSIONS Caregivers are at risk for use of restrictive feeding practices when their children are at higher BMI percentiles, and this association increases when caregivers use more ineffective stress regulation practices and their children are homozygous for the Met allele. Prevention programmes might focus on parenting behaviours that foster emotion regulation and consider variation in child responses to parenting.

Abstract
Eating disorders and obesity have become predominant in human society. Their association to modern lifestyle, encompassing calorie-rich diets, psychological stress, and comorbidity with major diseases are well documented. Unfortunately the biological basis remains elusive and the pharmacological treatment inadequate, in part due to the limited availability of valid animal models. Human research on binge eating disorder (BED) proves a strong link between stress exposure and bingeing: state-levels of stress and negative affect are linked to binge eating in individuals with BED both in laboratory settings and the natural environment. Similarly, classical animal models of BED reveal an association between acute exposure to stressors and binging but they are often associated with unchanged or decreased body weight, thus reflecting a negative energy balance, which is uncommon in humans where most commonly BED is associated with excessive or unstable body weight gain. Recent mouse models of subordination stress induce spontaneous binging and hyperphagia, altogether more closely mimicking the behavioral and metabolic features of human BED. Therefore the translational relevance of subordination stress models could facilitate the identification of the neurobiological basis of BED and obesity-associated disease and inform on the development of innovative therapies.
