State negative affect in relation to loss-of-control eating among children and adolescents in the natural environment. Appetite 2022; 178:106166. [PMID: 35850381 PMCID: PMC9452488 DOI: 10.1016/j.appet.2022.106166] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 06/21/2022] [Accepted: 07/08/2022] [Indexed: 11/25/2022]
Abstract
Affect regulation theory proposes that loss-of-control (LOC)-eating is preceded by increases and followed by decreases in negative affect (NA), but empirical tests of this theory among pediatric samples in the natural environment are needed. Using an ecological momentary assessment approach, we conducted post-hoc analyses to examine LOC-eating severity reported during post-meal surveys in relation to the intensity of composite NA and NA components (anger, anxiety, depression, guilt) throughout the day for two weeks in a cohort of healthy children and adolescents. Multilevel models tested the associations among LOC-eating severity and NA components reported at pre-meal surveys (t-1), post-meal surveys (t), and lagged post-meal surveys (t+1). Models were adjusted for sex, age, race/ethnicity, height, fat mass, socioeconomic status, and time between the occurrence and report of eating episodes; post-meal analyses were also adjusted for pre-meal NA. Participants age 8-17 (N = 100; 55% female; 45% male; 12.83 ± 2.73y; 24% with overweight/obesity) recorded 2410 eating episodes. Pre-meal composite NA and NA components were not associated with LOC-eating severity at the subsequent meal. LOC-eating severity was positively associated with post-meal depression (β = 0.042, 95% CI = 0.007, 0.076) and guilt (β = 0.056, 95% CI = 0.017, 0.095), but not composite negative affect, anger, or anxiety. The positive association among LOC-eating severity and guilt persisted in lagged post-meal analyses (β = 0.075, 95% CI = 0.021, 0.128). Contrary to affect regulation theory and laboratory data, but consistent with prior ecological momentary assessment data in children and adolescents, pre-meal NA was not linked to subsequent LOC-eating. Increased guilt following meals may be a mechanism for the development of exacerbated disordered eating. Longitudinal studies may elucidate how NA is implicated in the etiology of pediatric eating disorders.

Abstract
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.

Abstract
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.

Abstract
PURPOSE OF REVIEW Loss-of-control (LOC) eating, the subjective feeling of being unable to control what or how much is being consumed, is common. The purpose of this review was to examine the relationships among LOC eating, cardiometabolic health, and weight management intervention outcomes. RECENT FINDINGS In youth and adults, LOC eating is associated with and predictive of psychological symptoms, high weight, and worsened cardiometabolic health. While LOC eating pre-intervention does not appear to impact outcomes, LOC eating during or following is associated with worsened outcomes from behavioral and surgical weight management interventions. When individuals are undergoing weight management interventions, it may be important to regularly assess for LOC eating. There is limited research on the examined relationships in diverse populations (e.g., males, individuals of a lower socio-economic status, racial/ethnic minority groups). Future research should examine these relationships across the lifespan in diverse populations, with a focus on how these relationships can be impacted through targeted interventions.

Abstract
OBJECTIVE Depression in adolescence is linked to risk for type 2 diabetes (T2D). In this secondary data analysis of a randomized controlled trial comparing cognitive-behavioral therapy (CBT) to a control program to ameliorate insulin resistance via reducing depression symptoms, we examine which CBT change mechanisms (e.g., behavioral activation, cognitive restructuring) contributed to decreased depression and subsequent improvements in body mass index (BMI), percent body fat, and insulin resistance. METHODS Girls 12-17y with overweight/obesity and family history of T2D were randomized to six-week group CBT (n = 61) or health education (HealthEd; n = 58). At baseline and post-treatment, adolescents completed questionnaires assessing activities, thoughts, and depression symptoms. At baseline, post-treatment, and one-year, BMI was calculated and insulin outcomes were derived from two-hour oral glucose tolerance testing. At baseline and one-year, percent body fat was assessed with dual-energy x-ray absorptiometry. Indirect effects of CBT components were tested on one-year changes in BMI, percent body fat, and insulin indices through decreases in depression symptoms during treatment. Intervention was tested as a moderator. RESULTS In CBT, but not HealthEd, there was an indirect effect of increased physical activity during treatment on decreased one-year BMI via reductions in depression symptoms during treatment. Also, there were conditional indirect effects in CBT of increased pleasantness of physical and social activity during treatment on decreased one-year BMI via decreased depression symptoms during treatment. CONCLUSION Behavioral activation may be a useful intervention to decrease depression and reduce excess weight gain in the targeted prevention of T2D in at-risk adolescent girls.

Retrieval-induced forgetting in children and adolescents with and without obesity. Int J Obes (Lond) 2022; 46:851-858.

Abstract
BACKGROUND/OBJECTIVES Previous research indicates that youth with obesity exhibit deficits in executive functioning (EF), which often take the form of impaired response inhibition. One aspect of EF not previously studied in obesity is the adaptive process known as retrieval-induced forgetting (RIF), the suppression/inhibition of intrusive or non-target items by the retrieval of specific items from memory. The present study investigated if child or adolescent obesity disrupts the ability to inhibit retrieval of intrusive memories. SUBJECTS/METHODS We compared the manifestation of RIF in children (ages 8-12) and adolescents (ages 13-18) as a function of their weight status and sex. We also evaluated the effects of these variables on simple recall of items from episodic memory under conditions where competition from intrusive items was reduced. RESULTS Children with obesity did not demonstrate significant RIF, whereas RIF was exhibited by preteens without obesity and by teenage participants with- and without obesity (Weight Status × Age Group interaction p = 0.028). This pattern of results did not differ as a function of sex for either age group. No differences in episodic memory were found. Additional analyses using Age as continuous covariate (and not as a nominal group) comparing participants who exhibited RIF with those who did not, found that the no RIF group consumed fast-food meals more frequently (p = 0.024) and had higher percentages of total body adiposity and android fat compared to the RIF group (p's < 0.05). CONCLUSIONS The findings expand what is known about the effects of childhood obesity on cognitive functioning, identify impaired RIF with specific behavioral and dietary factors and increased adiposity, and suggest the possibility that impairments in the ability to inhibit intrusive memories of food and eating may contribute to poor early-life weight control.

Abstract
BACKGROUND Children whose parents have type 2 diabetes (T2D) are at high-risk for developing T2D. In youth, negative affect has been shown to predict insulin resistance (IR), and disinhibited-eating behaviors have been linked to IR. It is unknown if youth with a parent with T2D (P-T2D) report greater psychological and behavioral symptoms than those without a P-T2D. OBJECTIVE To compare youth with and without a P-T2D on symptoms of negative affect and disinhibited-eating. METHODS Nine-hundred thirty-two youth (13.3 ± 2.6 years; BMIz 1.06 ± 1.06; 67.8% female; 53.6% people of color; 10.7% with a P-T2D) completed questionnaires of anxiety and depressive symptoms, eating in the absence of hunger, and emotional-eating. Loss-of-control (LOC)-eating was assessed by interview. In two separate subsamples, energy intake was explored using laboratory test meals simulating eating in the absence of hunger and LOC-eating, respectively. Analyses were adjusted for age, sex, race/ethnicity. In follow-up analyses, fat mass (kg) and height, and IR were included as covariates, respectively. RESULTS Adjusting for all covariates including adiposity and IR, compared to youth without a P-T2D, youth with a P-T2D reported more anxiety and depression symptoms, greater eating in the absence of hunger, and emotional-eating (ps < 0.05). No significant differences were found for LOC-eating, or in exploratory analyses of energy intake for either test meal (ps > 0.16). CONCLUSIONS Self-reported negative affect and disinhibited-eating may be higher among youth with P-T2D compared to those without P-T2D. Prospective studies should examine, among those with a P-T2D, what role such symptoms may play for their subsequent risk for T2D.

Abstract
BACKGROUND Inconsistent sleep patterns may promote excess weight gain by increasing food cravings and loss-of-control (LOC)-eating; however, these relationships have not been elucidated in youth. OBJECTIVE We tested whether sleep duration and timing were associated with food cravings and LOC-eating. METHOD For 14 days, youths wore actigraphy monitors to assess sleep and reported severity of food cravings and LOC-eating using ecological momentary assessment. Generalized linear mixed models tested the associations between weekly and nightly shifts in facets of sleep (i.e., duration, onset, midpoint, and waketime) and next-day food cravings and LOC-eating. Models were re-run adjusting for relevant covariates (e.g., age, sex, adiposity). RESULTS Among 48 youths (12.88 ± 2.69 years, 68.8% female, 33.3% with overweight/obesity), neither weekly nor nightly facets of sleep were significantly associated with food cravings (ps = 0.08-0.93). Youths with shorter weekly sleep duration (est. ß = -0.31, p = 0.004), earlier weekly midpoints (est. ß = -0.47, p = 0.010) and later weekly waketimes (est. ß = 0.49, p = 0.010) reported greater LOC-eating severity; findings persisted in adjusted models. CONCLUSIONS In youth, weekly, but not nightly, shifts in multiple facets of sleep were associated with LOC-eating severity; associations were not significant for food cravings. Sleep should be assessed as a potentially modifiable target in paediatric LOC-eating and obesity prevention programs.

Abstract
OBJECTIVE Beyond sleep duration, other facets of sleep such as variability and timing may be associated with obesity risk in youth. However, data are limited. Using a longitudinal design, this study tested whether multiple facets of sleep were associated with fat mass gain over 1 year. METHODS A convenience sample of non-treatment-seeking youth (age 8-17 years) wore actigraphy monitors for 14 days. Average weekly sleep duration, within-person sleep duration variability, weekend catch-up sleep, bedtime and wake time shift, social jet lag, bedtime, wake time, and sleep midpoint were calculated. The association of each facet of baseline sleep with 1-year fat mass, adjusting for baseline fat mass and height, was examined. RESULTS A total of 137 youths (54.0% female; mean [SD], age 12.5 [2.6] years; 28.4% non-Hispanic Black or African American; baseline fat mass = 15.3 [8.9] kg; 1-year fat mass = 17.0 [10.0] kg; 28.5% with baseline overweight or obesity) were studied. Wake time (p = 0.03) and sleep midpoint (p = 0.02) were inversely associated with 1-year fat mass, such that earlier wake time and midpoint were associated with higher 1-year fat mass. No other facet of sleep was significantly associated with 1-year fat mass (p > 0.09). CONCLUSIONS Using objective measures, youth with earlier wake times and sleep midpoints had greater gains in fat mass. Additional research is needed to determine whether sleep timing may be a modifiable target to prevent pediatric obesity.

Abstract
OBJECTIVE Among youth with overweight, food cravings (FC) are associated with loss-of-control (LOC)-eating, but the impact of sex-associated biological characteristics on this relationship is unknown. We examined whether sex and gonadal hormone concentrations moderated the relationships between FC and LOC-eating severity among healthy boys and girls across the weight strata in natural and laboratory environments. METHOD Using ecological momentary assessment (EMA), FC, and LOC-eating severity were reported 3-5 times a day for 2 weeks. In the laboratory, participants reported FC, consumed lunch from a buffet test meal designed to simulate LOC-eating, and rated LOC-eating severity during the meal. RESULTS Eighty-seven youth (13.0 ± 2.7 years, 58.6% female, 32.2% with overweight/obesity) participated. EMA measured general and momentary FC were positively associated with LOC-eating severity (ps < .01), with no differences by sex (ps = .21-.93). Estradiol and progesterone significantly moderated the relationships between FC and LOC-eating such that general FC and LOC-eating severity were only positively associated among girls with greater (vs. lower) estradiol (p = .01), and momentary FC and LOC-eating severity were only positively associated among girls with greater (vs. lower) progesterone (p = .01). Boys' testosterone did not significantly moderate the associations between FC and LOC-eating severity (ps = .36-.97). At the test meal, pre-meal FC were positively related to LOC-eating severity (p < .01), without sex or hormonal moderation (ps = .20-.64). DISCUSSION FC were related to LOC-eating severity in boys and girls. In the natural environment, gonadal hormones moderated this relationship in girls, but not boys. The mechanisms through which gonadal hormones might affect the relationship between FC and LOC-eating warrant investigation.

Abstract
OBJECTIVE Poorer executive function (EF) has been linked to disinhibited eating in youth, suggesting poor EF predisposes toward obesity, yet the specific nature and extent of interconnections between facets of these domains is unclear. Network analysis provides a promising framework for elucidating the relationship between poor EF and disinhibited eating, and offers insights into potential maintenance processes. METHOD Among youth ages 8-17 years, a regularized partial correlation network of EF and disinhibited eating facets was estimated to examine expected influence centrality and bridge expected influence. Computerized neurocognitive tasks assessed EF variables, including decision-making, general and food-related inhibitory control, delayed gratification, cognitive flexibility, and working memory. Disinhibited eating variables included total carbohydrate-fat intake at a laboratory test meal and self-reported eating in the absence of hunger, emotional eating, and loss-of-control eating severity. RESULTS In the current sample (N = 248; Mage = 12.5; 54.8% female; 43.5% non-Hispanic White; 25.8% non-Hispanic Black; BMI %ile = 65.8 ± 27.8), emotional eating in response to depressive symptoms emerged as a central symptom in the network. Carbohydrate-fat intake had the highest bridge expected influence and was most strongly connected to general inhibitory control (part r = .14). DISCUSSION The link between general inhibitory control and objective palatable food intake may be particularly salient in maintaining maladaptive eating behavior. Interventions targeting behavioral disinhibition may disrupt associations among a network of disinhibited eating facets in youth and should be targets for longitudinal research.

Abstract
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.

Abstract
Childhood loss of control (LOC)-eating, the perceived inability to stop or control eating, is associated with increased risk for binge-eating disorder and obesity. However, the correlates of LOC-eating in childhood remain unclear. A secondary analysis of 177, 7-12-year-old children from five laboratory feeding studies was performed to investigate potential family (e.g., frequency of meals together, feeding practices), parental (e.g., education, weight status), and child (e.g., weight status, appetite traits) correlates of LOC-eating. Association rules mining (ARM1), a data-driven approach, was used to examine all characteristics that were common across studies to identify which were associated with LOC-eating. Results showed LOC-eating was characterized by a combination of child appetitive behaviors and parental feeding practices. In particular, LOC-eating was associated with low parental pressure to eat in combination with a high propensity to want to eat all the time and frequent refusal or dislike of novel foods. This pattern of both food approach (i.e., wanting to eat all the time) and avoidant behaviors (i.e., food fussiness) highlights the need for more research to characterize the complex patterns of appetitive traits associated with LOC-eating. In contrast, the absence of LOC-eating was associated with a low propensity to want to eat all the time, greater family income, and infrequent emotional overeating. Therefore, propensity to want to eat all the time, a single question from the Children's Eating Behavior Questionnaire, characterized both the presence and absence of LOC-eating, highlighting the need for more research to determine if this question captures clinically relevant individual differences. Future studies addressing these questions will advance our understanding of pediatric LOC-eating and may lead to interventions to reduce risk for more severe eating disorder symptomology.

Abstract
BACKGROUND Research among adults suggests that weight stigma is associated with worsened cardiometabolic health. However, these relationships have not been examined among youth. OBJECTIVE Assess associations between weight-based teasing (WBT) and metabolic and inflammatory markers among two samples of youth: (1) a non-treatment-seeking sample and (2) a weight loss treatment-seeking sample with obesity. METHOD Weight, height, adiposity, waist circumference and blood pressure were measured. Fasting blood samples were collected for metabolic (triglycerides, glucose, high-density lipoprotein cholesterol) and inflammatory analytes (high-sensitivity C-reactive protein in Study 1 and erythrocyte sedimentation rate in both studies). Youths completed the Perception of Teasing Scale, a measure of WBT. Metabolic and inflammatory indices were compared between those with and without teasing, adjusting for demographics and body composition. RESULTS Study 1 enrolled 201 non-treatment-seeking youth (Mage = 13.1y; 54.2% female; 44.8% non-Hispanic White; 32.8% with overweight/obesity); 15.4% reported WBT. Study 2 enrolled 111 treatment-seeking adolescents with obesity (Mage = 14.0y; 66.7% female; 37.8% non-Hispanic White); 73.0% reported WBT. Adjusting for covariates, WBT was not associated with cardiometabolic risk factors in either study. CONCLUSIONS WBT was not associated with worsened cardiometabolic health. Longitudinal research is needed to elucidate associations between WBT and health in youth.

Abstract
Background: Among adults, weight stigma is associated with markers of poor cardiometabolic health. Although weight-based teasing (WBT) is common among youth with high body weight, few studies have examined its associations with cardiometabolic markers. Owing to unique stressors (e.g., parental deployment and frequent moves), military-dependent youth may be at particularly high risk for obesity, WBT, and poor cardiometabolic health. We, therefore, assessed associations between WBT and cardiometabolic health markers among adolescent military dependents presenting for a weight gain prevention trial. Methods: Participants underwent fasting phlebotomy; had fasting weight, height, and waist circumference measured; and completed assessments of WBT, anxiety, and loss-of-control eating. Multivariate analysis of covariance, adjusting for relevant covariates including demographics and body composition, was used to examine differences in metabolic syndrome (MetS) components (waist circumference, systolic and diastolic blood pressure, high-density lipoprotein cholesterol, triglycerides, and glucose) between youth reporting WBT and youth reporting no WBT. Bootstrapped models examined whether WBT mediated the relationship between BMIz and MetS components. Results: Data from 142 youth (57.7% female; 14.4 ± 1.6 years; 51.2% non-Hispanic White, 20.9% non-Hispanic Black; BMIz: 1.9 ± 0.4) were analyzed. WBT was not significantly associated with any MetS component. Relationships were observed between BMIz and all MetS components (except systolic blood pressure and glucose), although WBT did not significantly mediate these relationships (p's > 0.05). Conclusions: This study did not find support for a relationship between WBT and MetS components in adolescent military dependents at risk for adult obesity. Prospective research is needed to determine whether associations between WBT and adverse cardiometabolic outcomes emerge primarily in adulthood.

Abstract
INTRODUCTION Adolescent military-dependents face unique psychosocial stressors due to their parents' careers, suggesting they may be particularly vulnerable to excess weight gain and symptoms of depression and anxiety. Despite these risk factors, there is a lack of tested preventative interventions for these youths. Given the transient nature of military family deployments, research may be hindered due to difficulty in collecting long-term prospective outcome data, particularly measured height and weight. The primary aim of this study was to examine the feasibility and acceptability of collecting body mass index (BMI, kg/m2) outcome data up to 2 years following a randomized controlled pilot trial of an adapted interpersonal psychotherapy (IPT) program aimed at preventing excess weight gain and improving psychological functioning for adolescent military-dependents. In exploratory analyses, patterns in body composition over time were examined. MATERIALS AND METHODS Twenty-seven adolescent military-dependent girls (baseline: Mage: 14.4 ± 1.6 years; MBMI: 30.7 ± 4.9 kg/m2; MBMI-z: 1.9 ± 0.4) participated in this study. After a baseline assessment, utilizing a computerized program to create a randomization string, girls were assigned to either an IPT or a health education (HE) program. Participants completed three follow-up visits (posttreatment, 1-year follow-up, and 2-year follow-up). Girls completed a Treatment Acceptability Questionnaire at posttreatment; at all time points, height and fasting weight were collected. For the primary aim, Fisher's exact tests examined the rate of obtained follow-up data and lost to follow-up status between the two groups, Mann-Whitney U tests examined the session attendance between groups, and treatment acceptability ratings were compared between the two groups at posttreatment using an independent samples t-test. For the exploratory aim, one-way analyses of covariance (ANCOVAs) examined the group differences in BMI at each time point, adjusting for baseline values, and paired samples t-tests examined the within-group differences at each time point relative to baseline. Using imputed data in the full intent-to-treat sample, mixed model ANCOVAs were conducted to examine the group differences over time. RESULTS Across both groups, girls attended an average of 72.0% of sessions. At least partial data were collected at posttreatment, 1-year follow-up, and 2-year follow-up for 96.3%, 85.2%, and 74.1% of the participants, respectively. There were no significant group differences in follow-up data collection rates, follow-up status, number of sessions attended, or treatment acceptability. BMI-z stabilized across groups, and there were no group differences in BMI-z. In adjusted ANCOVA models with imputed data, no significant group-by-time effects emerged. CONCLUSIONS For this randomized controlled prevention trial, long-term outcome data collection of measured BMI was possible in adolescent military-dependents and IPT was an acceptable and feasible intervention. An adequately powered trial is required to assess the efficacy of this intervention among military-dependents for obesity prevention and improvements in BMI.

Inhibitory control and negative affect in relation to food intake among youth. Appetite 2021; 156:104858. [PMID: 32891676 PMCID: PMC7669609 DOI: 10.1016/j.appet.2020.104858] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 09/01/2020] [Accepted: 09/01/2020] [Indexed: 12/12/2022]
Abstract
Negative affect and poor inhibitory control are related to disinhibited eating behaviors in youth and may contribute to the development and/or maintenance of obesity. Although few studies have jointly examined these constructs in youth, it has been theorized that poor inhibitory control may be driven by negative affect. If supported, impaired inhibitory control, driven by negative affect, could represent a modifiable neurocognitive treatment target for disinhibited eating. The current study examined whether inhibitory control mediates the relationship between negative affect and eating among youth. Youth (8-17 years) participated in a Food Go/No-Go neurocognitive task to measure inhibitory control as the percentage of commission errors. A composite negative affect score was created from self-report measures of anxiety and depression. A laboratory buffet meal modeled to simulate disinhibited eating was used to measure total and snack food intake. Cross-sectional mediation models with bias-corrected bootstrap confidence intervals (CI) were conducted using negative affect as the independent variable, inhibitory control as the mediator, and intake patterns as dependent variables. One-hundred-eighty-one youths (13.2 ± 2.7y; 55% female; BMIz 0.6 ± 1.0) were studied. Total Go/No-Go commission errors mediated the relationship between negative affect and total intake (95%CI = [0.3, 31.6]), but not snack intake (95%CI = [-2.5, 7.3]). Commission errors for Food-Go blocks significantly mediated the relationship between negative affect and total intake (95%CI = [7.7, 44.4]), but not snack intake (95%CI = [-3.4, 9.5]). Commission errors on Neutral-Go blocks did not significantly mediate any of these relationships. Negative affect may lead to poorer inhibitory control as well as a stronger approach tendency toward food, increasing the likelihood of engaging in disinhibited eating. Future research should determine if, in combination with approaches to reduce negative affect, improved inhibitory control could help prevent overeating in youths with depressive or anxiety symptoms.

Abstract
OBJECTIVE Military-dependent youth appear to be at greater risk for disordered-eating than their civilian counterparts. Permanent change of station moves (PCS-moves), typically occurring every 2-3 years, are commonly experienced by adolescent military-dependents. However, the links between PCS-moves and disordered-eating in this population have not been explored. We hypothesized that stress arising from PCS-moves may contribute to the development and/or exacerbation of disordered-eating. METHODS One-hundred-forty-nine adolescent military-dependents with overweight or obesity (59.7% female; 46.3% non-Hispanic White; 14.4±1.5 years; BMI-z: 1.9±0.4) completed measures before commencing an adulthood obesity and binge-eating disorder prevention trial for adolescents at-risk for both conditions due to BMI percentile ≥85th and loss-of-control (LOC)-eating and/or elevated anxiety symptoms. Disordered-eating attitudes and LOC-eating were assessed by semi-structured interview, and emotional eating was self-reported. Adjusting for relevant covariates, multiple linear regressions examined the unique association of PCS-move frequency with disordered-eating attitudes and disinhibited-eating behaviors. RESULTS PCS-move frequency was not significantly associated with either LOC-eating frequency (β = 0.09, p = .27) or emotional eating (β = -0.04, p = .62). However, PCS-move frequency was positively associated with disordered-eating attitudes (β = 0.17, p = .04), which appeared to be primarily driven by shape concerns (β = 0.21, p = .01). DISCUSSION Findings indicate that frequency of PCS-moves is related to disordered-eating attitudes, but not behaviors. Longitudinal research is needed to understand if PCS-moves prospectively relate to the onset and/or exacerbation of disordered-eating, and the relevance of disordered-eating attitudes as opposed to disinhibited-eating behaviors.

Abstract
OBJECTIVE Military adolescent boys report similar levels of disordered-eating as their female counterparts. Yet, interventions for the prevention of full-threshold eating disorders in adolescent boys are lacking. Interpersonal psychotherapy (IPT), an evidenced-based therapy adapted for the prevention of BED and adult obesity, has been studied in adolescent girls, but it is unclear whether IPT might resonate with adolescent boys. METHOD The current case study elucidates the use of a 12-week IPT group intervention for the prevention of BED and adult obesity in adulthood for an African American adolescent military dependent boy with reported loss-of-control (LOC)-eating, obesity, and elevated mood symptoms. RESULTS LOC-eating and body mass index metrics decreased immediately post-intervention and further decreased by one-year follow-up. Social functioning scores improved and anxiety and depression scores decreased from baseline to one-year follow-up. In contrast to previous observations among girls, these improvements were evidenced without the teen's explicit acknowledgement of the link between mood and eating behaviors. DISCUSSION Although the mechanism of change may manifest differently than for girls, adapted IPT may be an effective intervention strategy for adolescent boys with LOC-eating and obesity who endorse elevated mood symptoms.

Abstract
BACKGROUND Metabolic syndrome in adolescence has been associated with adverse cardiometabolic outcomes in adulthood. Preliminary data suggest that boys may have worsened metabolic syndrome components compared to girls. Yet, little is known about the physical health of military dependents, a potentially at-risk population. OBJECTIVE Examine sex differences in metabolic syndrome components in a sample of adolescent military dependents. METHODS Participants were adolescents (N = 139; 14.4 ± 1.6 years; 45.3% male; 41.0% non-Hispanic White, 19.4% non-Hispanic Black; BMI-z: 1.9 ± 0.4) 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. A multivariate analysis of covariance was conducted to compare objectively measured metabolic syndrome components across boys and girls. Covariates were age, race, loss-of-control eating status, anxiety symptoms, and BMI-z. RESULTS Metabolic syndrome components differed by sex (P = .01). Boys had higher systolic blood pressure (P = .049), lower high-density lipoprotein cholesterol (P = .01), and higher glucose (P = .001) than girls. Waist circumference, diastolic blood pressure, and triglycerides did not differ between boys and girls (P > .05). CONCLUSIONS Future research should prospectively examine these relationships into adulthood. If the current findings are supported, prevention programs should consider targeting cardiometabolic health particularly among male adolescent military dependents.

Abstract
BACKGROUND Previous research has implicated demographic, psychological, behavioral, and cognitive variables in the onset and maintenance of pediatric overweight/obesity. No adequately-powered study has simultaneously modeled these variables to assess their relative associations with body mass index (BMI; kg/m2) in a nationally representative sample of youth. METHODS Multiple machine learning regression approaches were employed to estimate the relative importance of 43 demographic, psychological, behavioral, and cognitive variables previously associated with BMI in youth to elucidate the associations of both fixed (e.g. demographics) and potentially modifiable (e.g. psychological/behavioral) variables with BMI in a diverse representative sample of youth. The primary analyses consisted of 9-10 year olds divided into a training (n = 2724) and test (n = 1123) sets. Secondary analyses were conducted by sex, ethnicity, and race. RESULTS The full sample model captured 12% of the variance in both the training and test sets, suggesting good generalizability. Stimulant medications and demographic factors were most strongly associated with BMI. Lower attention problems and matrix reasoning (i.e. nonverbal abstract problem solving and inductive reasoning) and higher social problems and screen time were robust positive correlates in the primary analyses and in analyses separated by sex. CONCLUSIONS Beyond demographics and stimulant use, this study highlights abstract reasoning as an important cognitive variable and reaffirms social problems and screen time as significant correlates of BMI and as modifiable therapeutic targets. Prospective data are needed to understand the predictive power of these variables for BMI gain.

Abstract
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.

Abstract
BACKGROUND Executive functioning (EF) difficulties may be associated with problems regulating eating behaviours. Few studies have evaluated this question in youth using diverse measures of EF or objective measures of energy intake. METHODS The current study used neuropsychological tasks and a laboratory test meal to evaluate the links between EF and youth's disinhibited eating patterns. Two-hundred-five nontreatment seeking youth (M age = 13.1 ± 2.8 years; M BMIz = 0.6 ± 1.0; 33.2% overweight; 54.1% female) completed tasks measuring decision making, general and food-specific behavioural disinhibition, willingness to delay gratification for food and money, cognitive flexibility, and working memory. Age (children vs adolescents) was examined as a moderator. All analyses adjusted for demographic factors, pubertal status, lean mass (kg), fat mass (%), height, general intellectual functioning, and depressive symptoms. RESULTS After adjusting for multiple comparisons, more general behavioural disinhibition was associated with greater total energy intake (P = .02), and poorer cognitive flexibility was associated with more fat intake (P = .03) across all ages. Poorer decision making in children (P = .04), but not adolescents (P = .24), was associated with greater fat intake. Food-specific behavioural disinhibition, the ability to delay gratification for both food and monetary rewards, and working memory were not significantly associated with youth's disinhibited eating patterns during a single meal. CONCLUSIONS Most domains of EF were not associated with youth's disinhibited eating. Significant associations may highlight the need to target specific cognitive processes, particularly behavioural disinhibition, decision making, and cognitive flexibility, in potential intervention strategies for children's disinhibited eating.

Abstract
OBJECTIVE Depression is linked to excess weight, insulin resistance, and type 2 diabetes (T2D). We previously reported that in adolescent girls at-risk for T2D with moderately elevated depression, randomization to cognitive-behavioral therapy (CBT) produced greater decreases in depression at post-treament and greater decreases in fasting/2-h insulin at 1 year, compared to health education (HE). The current study is a secondary analysis of this parallel-group randomized controlled trial. We examined whether decreasing depression explained intervention effects on body composition and insulin outcomes. We hypothesized that decreases in depression would be an explanatory mediator and that indirect effects would be strongest at higher levels of baseline depression. METHODS Participants were 12-17 years girls with overweight/obesity and family history of T2D randomized to 6-week group CBT (n = 58) or HE (n = 61). Procedures took place at an outpatient pediatric clinic. At baseline, post-treatment, and 1 year, adolescents completed the Center for Epidemiologic Studies-Depression Scale to assess depression symptoms; body mass index (BMI [kg/m2]) was measured from height/fasting weight; insulin resistance was derived from 2-h oral glucose testing. Adiposity was assessed with dual-energy X-ray absorptiometry at baseline and 1 year. Indirect effects of intervention were tested on 1-year changes in BMI, adiposity, and insulin through decreases in depression. Baseline depression was tested as a moderator of mediation. RESULTS There was an indirect effect of CBT on decreased 1-year fasting insulin via decreases in depression during treatment, among adolescents with more elevated baseline depression. CONCLUSIONS Decreasing elevated depression may be one mechanism in the targeted prevention of T2D in at-risk adolescents.
