RESUMO

Gaudiani et al. (2022) presented terminal anorexia nervosa (T-AN) as a potential new specifier to the anorexia nervosa (AN) diagnosis, with criteria including (a) AN diagnosis, (b) age > 30 years, (c) previously participated in high-quality care, and (d) the clear, consistent determination by a patient with decision-making capacity that additional treatment would be futile, knowing death will result. This study's purpose was to empirically examine a subgroup of participants with AN who met the first three criteria of T-AN-and a smaller subset who also met a proxy index of the fourth criterion involving death (TD-AN)-and compare them to an adult "not terminal" anorexia nervosa (NT-AN) group and to a "not terminal" subset 30 years of age or older (NTO-AN). Patients at U.S. eating disorder treatment facilities (N = 782; T-AN: n = 51, TD-AN: n = 16, NT-AN: n = 731, NTO-AN: n = 133), all of whom met criteria for a current Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnosis of AN, were compared regarding admission, discharge, and changes from admission to discharge on physiological indices (i.e., white blood cell counts, albumin levels, aspartate aminotransferase levels, and body mass index), as well as self-report measures (i.e., eating disorder, depression, anxiety, and obsessive-compulsive symptoms). In contrast to the tight syndromal symptom interconnections of, and inevitable spiral toward death expected for, a terminal diagnosis, results suggest substantial variability within the T-AN group and TD-AN subset, and an overall trend of improvement across physiological and self-report measures. This study thus provides some empirical evidence against the specification of the T-AN diagnosis. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

OBJECTIVE: Reward and punishment sensitivity are known to be altered in anorexia nervosa (AN). Most research has examined these constructs separately although motivated behavior is influenced by considering both the potential for reward and risk of punishment. The present study sought to compare the relative balance of reward and punishment sensitivity in AN versus healthy controls (HCs) and examine whether motivational bias is associated with AN symptoms and treatment outcomes. METHODS: Adolescents and adults with AN (n = 262) in a partial hospitalization program completed the Eating Disorders Examination Questionnaire (EDE-Q), Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scales, and Sensitivity to Punishment/Sensitivity to Reward Questionnaire (SPSRQ) at admission and discharge. HCs (HC; n = 90) completed the BIS/BAS and SPSRQ. Motivational Bias Scores were calculated to reflect the dominance of reward versus punishment sensitivity. RESULTS: Individuals with AN demonstrated significantly greater bias toward punishment sensitivity than HC. In AN, a bias toward punishment was associated with higher EDE-Q Global score at admission. Change in motivational bias during treatment predicted EDE-Q Global scores, but not BMI, at discharge, with greater increases in reward sensitivity or greater decreases in punishment sensitivity during treatment predicting lower eating pathology. Similar findings were observed using the BIS/BAS and SPSRQ. DISCUSSION: Change in motivational bias during treatment is associated with improved outcomes in AN. However, it appears that much of the change in motivational bias can be attributed to changes in punishment sensitivity, rather than reward sensitivity. Future research should examine the mechanisms underlying punishment sensitivity decreases during treatment. PUBLIC SIGNIFICANCE: Sensitivity to reward and punishment may be important treatment targets for individuals with anorexia nervosa (AN). To date, most research has considered reward and punishment sensitivity separately, rather than examining their relationship to each other. We found that the balance of reward and punishment sensitivity (i.e., motivational bias) differs between healthy controls and those with AN and that this bias is associated with eating disorder symptoms and treatment outcome.

RESUMO

BACKGROUND: Chronic constipation (CC) is defined by symptom criteria reflecting heterogenous physiology. However, many patients with CC have significant psychological comorbidities-an alternative definition using a biopsychosocial classification model could be warranted to inform future treatments. We sought to: (1) empirically derive psychological symptom profiles of patients with CC using latent profile analysis and (2) validate these profiles by comparing them on symptom severity, GI-specific anxiety, body mass index (BMI), and anorectal manometry findings. METHODS: Participants included adults presenting for anorectal manometry for CC (N = 468, 82% female, Mage = 47). Depression/anxiety symptoms and eating disorder (ED) symptoms (EAT-26) were used as indicators (i.e., variables used to derive profiles) representing unique psychological constructs. Constipation symptoms, GI-specific anxiety, BMI, and anorectal manometry results were used as validators (i.e., variables used to examine the clinical utility of the resulting profiles). KEY RESULTS: A 5-profile solution provided the best statistical fit, comprising the following latent profiles (LPs): LP1 termed "high dieting, low bulimia;" LP2 termed "high ED symptoms;" LP3 termed "moderate ED symptoms;" LP4 termed "high anxiety and depression, low ED symptoms;" and LP5 termed "low psychological symptoms." The low psychological symptom profile (61% of the sample) had lower abdominal and overall constipation severity and lower GI-specific anxiety compared to the four profiles characterized by higher psychological symptoms (of any type). Profiles did not significantly differ on BMI or anorectal manometry results. CONCLUSIONS AND INFERENCES: Profiles with high psychological symptoms had increased constipation symptom severity and GI-specific anxiety in adults with CC. Future research should test whether these profiles predict differential treatment outcomes.

RESUMO

Binge-spectrum eating disorders (EDs; bulimia nervosa, binge eating disorder) often develop during adolescence and are associated with serious psychological and physical consequences. Current treatments for adolescents are highly behavioral in nature and while efficacious, many patients do not reach remission indicating that current treatments fail to target a key maintenance factor for EDs. One potential maintenance factor is poor family functioning (FF). In particular, high family conflict (e.g., arguing, critical comments) and low family cohesion (e.g., warmth, support) are known to maintain ED behaviors. Poor FF can (1) cause or exacerbate an adolescent's use of ED behaviors to cope with life stress and/or (2) inhibit parents from being a resource to adolescents during ED treatment. Attachment-Based Family Therapy (ABFT) is specifically designed to improve FF, and thus may be a promising adjunct to behavioral ED intervention strategies. ABFT, however, has not been tested in adolescents with binge-spectrum EDs. Thus, the current study is the first to evaluate a 16-week adapted ABFT treatment for adolescents with EDs (N = 8, Mage = 16.00, 71.43% female, 71.43% White) fusing together behavioral treatment for EDs with ABFT for highest possible impact. Eight families were treated in an open pilot trial to examine treatment feasibility, acceptability, and preliminary efficacy on FF and eating pathology. Overall, findings were promising. ABFT + B treatment was feasible and acceptable and showed preliminary evidence that it could improve FF and ED behaviors. Future research will test this intervention in a larger sample and further examine the role of FF in maintaining ED symptoms.

RESUMO

Sexual abuse or assault (SA) history is associated with eating disorder severity and psychiatric comorbidity, including post-traumatic stress disorder (PTSD). Beyond persistent alterations in mood and cognitions characterizing PTSD, PTSD due to SA may contribute to greater increases in negative affect and body image concerns following food intake in bulimic syndromes (BN-S). To test this, participants (n = 172) with BN-S who reported PTSD due to SA, PTSD due to other forms of trauma, or neither completed clinical interviews and momentary reports of negative affect and shape/weight preoccupation before and after food intake. Participants with PTSD, regardless of trauma source, reported higher purging frequency whereas PTSD due to SA was associated with more frequent loss of control eating. For one task, changes in negative affect following food intake differed across the three groups. Negative affect decreased significantly in participants with PTSD without SA whereas nonsignificant increases were observed in those with PTSD with SA. Results of the present study suggest that source of trauma in PTSD may impact likelihood that eating regulates affect and provide insight into ways current treatments may be adapted to better target purging in BN-S comorbid with PTSD.

RESUMO

Objective: Psychiatric disorders have been linked to poor social functioning, including deficits in relationship satisfaction. Treatments have shown strong effectiveness in reducing clinical symptoms for a range of disorders, though less is known of the effects disorder-focused treatments have on relationship satisfaction.Methods: The present study describes a systematic review that was conducted to determine the efficacy of treatments for specific psychiatric disorders in improving relationship satisfaction. Surprisingly, only seventeen studies were identified and included in the review.Results: We found that a majority of these studies reported modest improvement in relationship satisfaction among people who completed treatment. However, studies were severely hampered by methodological limitations, and all therapy-related improvements could be attributable to placebo effects or the passage of time.Conclusion: Important gaps in the literature were found that future research should seek to address to maximize treatment outcomes and psychosocial functioning.

RESUMO

OBJECTIVE: Maladaptive exercise (i.e., driven and/or compensatory exercise) is common in binge-spectrum eating disorders (EDs; e.g., bulimia nervosa, binge ED) and associated with adverse treatment outcomes. Alternatively, individuals with EDs are often also engaging in adaptive exercise (e.g., for enjoyment or health improvement), and increasing adaptive exercise may decrease ED symptoms. The current study aimed to understand which exercise episodes are likely to be maladaptive/adaptive so that interventions can appropriately decrease/increase maladaptive and adaptive exercise. METHOD: We used latent profile analysis (LPA) to identify pre-exercise affective profiles of 661 exercise episodes among 84 individuals with binge-spectrum EDs and examined associations between LPA-identified profiles and subsequent exercise motivations using ecological momentary assessment. RESULTS: A two-profile solution best fit our data: Profile 1 (n = 174), 'positive affectivity,' and Profile 2 (n = 487), 'negative affectivity.' Episodes in the 'negative affectivity' profile were more likely to be endorsed as both driven and intended to influence body shape/weight. Episodes in the 'positive affectivity' profile were more likely to be endorsed as exercising for enjoyment. CONCLUSIONS: Results support two phenotypes of exercise episodes, and differential associations of these phenotypes with adaptive and maladaptive motivations for exercise.

RESUMO

Inhibitory control, one's ability to inhibit automatic responses to desirable stimuli, may be inadequately targeted in interventions for loss-of-control eating (LOC). Promising evidence has identified inhibitory control trainings (ICTs) as an avenue to target inhibitory control directly; however, effects of ICTs on real-world behavior are limited. Compared to typical computerized trainings, virtual reality (VR) presents several potential advantages that may address key shortcomings of traditional ICTs, i.e. poor approximation to everyday life. The present study utilized a 2 × 2 factorial design of treatment type (ICT vs sham) by treatment modality (VR vs standard computer), which allows for increased statistical power by collapsing across conditions. Our primary aim was to examine the feasibility and acceptability of six weeks of daily training among groups. A secondary aim was to preliminarily assess main and interactive effects of treatment type and modality on target engagement and efficacy (i.e., training compliance, change in LOC episodes, inhibitory control, and implicit liking of foods). Participants (N = 35) with ≥1×/weekly LOC were assigned to one of four conditions and completed ICTs daily for six weeks. The trainings were feasible and acceptable, evinced by high retention and compliance across time and condition. Although completing daily trainings across treatment types and modalities was associated with large decreases in LOC, there were no meaningful effects of either treatment type or modality, nor a significant interaction effect, on LOC or mechanistic variables. Future research should aim to increase the efficacy of ICT (both standard and VR-based) and test in fully-powered clinical trials.

RESUMO

High rates of overlap exist between disorders of gut-brain interaction (DGBI) and eating disorders, for which common interventions conceptually conflict. There is particularly increasing recognition of eating disorders not centered on shape/weight concerns, specifically avoidant/restrictive food intake disorder (ARFID) in gastroenterology treatment settings. The significant comorbidity between DGBI and ARFID highlights its importance, with 13% to 40% of DGBI patients meeting full criteria for or having clinically significant symptoms of ARFID. Notably, exclusion diets may put some patients at risk for developing ARFID and continued food avoidance may perpetuate preexisting ARFID symptoms. In this review, we introduce the provider and researcher to ARFID and describe the possible risk and maintenance pathways between ARFID and DGBI. As DGBI treatment recommendations may put some patients at risk for developing ARFID, we offer recommendations for practical treatment management including evidence-based diet treatments, treatment risk counseling, and routine diet monitoring. When implemented thoughtfully, DGBI and ARFID treatments can be complementary rather than conflicting.

RESUMO

Eating disorders include a spectrum of disordered thinking patterns and behaviours around eating. There is increasing recognition of the bi-directional relationship between eating disorders and gastrointestinal disease. Gastrointestinal symptoms and structural issues might arise from eating disorders, and gastrointestinal disease might be a risk factor for eating disorder development. Cross-sectional research suggests that individuals with eating disorders are disproportionately represented among people seeking care for gastrointestinal symptoms, with avoidant-restrictive food intake disorder in particular garnering attention for high rates among individuals with functional gastrointestinal disorders. This Review aims to describe the research to date on the relationship between gastrointestinal disorders and eating disorders, highlight research gaps, and provide brief, practical guidance for the gastroenterology provider in detecting, potentially preventing, and treating gastrointestinal symptoms in eating disorders.

RESUMO

OBJECTIVE: Despite evidence supporting the link between dietary restraint (i.e., attempts at dietary restriction) and loss of control (LOC) eating among individuals with binge-spectrum eating disorders (EDs), some research suggests that dietary restraint may not be linked to LOC eating in all contexts. It is currently unknown how often dietary restraint results in successful dietary restriction, or which types of restraint/restriction confer highest risk for LOC eating. Furthermore, little research has evaluated momentary, temporal associations between dietary restraint and LOC eating. Thus, the present study aimed to (1) characterize dietary restraint and restriction, among individuals with LOC eating, and (2) examine temporal relationships between restraint/restriction and LOC eating within- and between-subjects. METHOD: The current study recruited adults with binge spectrum EDs (n = 96, 80.4% female) to complete a 7-14-day ecological momentary assessment protocol assessing ED symptoms. Multilevel models and linear regression evaluated within- and between-subjects associations between momentary restraint/restriction and LOC eating, respectively. RESULTS: Attempted avoidance of enjoyable foods, limiting the amount eaten, and any restraint predicted greater likelihood of LOC eating at the next survey. Attempts to delay eating predicted reduced likelihood of LOC eating at the next survey, though this effect was no longer statistically significant after correcting for multiple comparisons. Diagnostic presentation moderated the association between attempted avoidance of enjoyable foods and LOC eating such that this association was significantly stronger for those on the BN-spectrum. DISCUSSION: Dietary restraint seems to be more predictive of LOC eating than dietary restriction both within- and between-subjects. Future treatments should target dietary restraint to reduce LOC eating. PUBLIC SIGNIFICANCE: Some research suggests that dietary restriction (i.e., reduced calorie intake) and restraint (i.e., attempted restriction) may not be linked to LOC eating in all contexts. We found that dietary restraint is more predictive of LOC eating than dietary restriction both within and between individuals. Future treatments should target dietary restraint to reduce LOC eating.

RESUMO

OBJECTIVE: Although altered reward processing is proposed to play a key role in obesity maintenance, the role of food enjoyment and enjoyment of non-food naturally rewarding activities ("non-food enjoyment") in obesity maintenance remains unknown. This study examined how food and non-food enjoyment were associated with baseline body mass index (BMI) and weight loss (WL) following year-long behavioral WL treatment. METHODS: At baseline, participants (MAge = 51.81; 73.8 % White, N = 279) with overweight/obesity completed a 7-day ecological momentary assessment (EMA) protocol inquiring about pleasure/enjoyment derived from eating and non-food activities over the past few hours. Participants also completed retrospective self-report measures of food/non-food enjoyment. With linear regressions, associations between EMA food/non-food enjoyment and BMI and post-treatment WL were examined. Race was included as a covariate. RESULTS: EMA and retrospective food/non-food enjoyment measures had modest concordance, providing preliminary psychometric support for the EMA measures. Partially consistent with hypotheses, greater EMA food enjoyment was associated with lower BMI (B = -1.03, p = .01) and with greater WL, though the latter association was not statistically significant (B = 1.15, p = .07). Exploratory analyses suggested that race was associated with food enjoyment (non-White participants had greater food enjoyment than White participants, d = 0.81, p = .005), and that race may have affected associations between food enjoyment and weight outcomes. Associations between non-food enjoyment and weight outcomes were small and nonsignificant (ps > .93). CONCLUSIONS: Results suggest enjoyment from food, but not from non-food domains, is associated with weight outcomes.

RESUMO

INTRODUCTION: Specific characteristics of sleep (e.g., duration, quality, and fatigue) are positively associated with (ED) behaviors, specifically binge eating (BE) potentially through decreased self-regulation and increased appetite. However, prior work has been largely cross-sectional and has not examined temporal relationships between sleep characteristics and next-day ED behaviors. Thus, the present study examined daily relationships between sleep and ED behaviors among individuals with binge-spectrum EDs. METHOD: Participants (N = 96) completed 7 daily ecological momentary assessment (EMA) surveys over 7-14 days; morning surveys assessed sleep characteristics and 6 randomly timed surveys each day captured ED behaviors. Analyses examined within-subject and between-subject effects of sleep quality, duration, and fatigue on BE, compensatory purging behaviors, and maladaptive exercise. RESULTS: Within-subject sleep quality was significantly negatively associated with engagement in maladaptive exercise later that day. Additionally, between-subject sleep duration was significantly negatively associated with engagement in compensatory purging behaviors. DISCUSSION: Within- and between-subjects associations between sleep quality and duration and compensatory behavior engagement indicate that sleep plays an important role in ED behaviors. Future research should incorporate sensor-based measurement of sleep and examine how specific facets of sleep impact BE and treatment response. LEVEL OF EVIDENCE: Level II: Evidence obtained from controlled trial without randomization.

RESUMO

OBJECTIVE: Prior work evaluating cognitive flexibility (i.e., the ability to alter behavior in response to environmental changes) in bulimia-spectrum eating disorders (BN-ED) has produced mixed findings, perhaps due to reliance on set-shifting paradigms that do not effectively isolate cognitive flexibility. Task-switching paradigms are more precise, but no study has examined task-switching in BN-ED. Further, no study has examined whether cognitive flexibility deficits in BN-ED are disorder-specific (e.g., confined to food-related responses). Thus, the present study re-evaluated cognitive flexibility in BN-ED using general and food-specific task-switching paradigms. METHOD: Individuals with BN-ED (n = 28) and healthy controls (HC; n = 39) completed a cued color-shape switching task (CCSST) and a novel food-specific variation (FCCSST). We compared BN-ED and HC on switch costs (reflective of transient task-switching) and mix costs (reflective of maintenance of switching behavior). RESULTS: Switch and mix costs were not significantly different between BN-ED and HC in terms of either accuracy or reaction time on the CCSST or FCCSST. CONCLUSIONS: Findings suggest neither general nor food-specific cognitive flexibility is impaired in BN-ED. Rigidity in BN-ED (e.g., continued engagement in compensatory behaviors despite psychoeducation that these behaviors are ineffective for weight loss) may be a result of other neurocognitive impairments rather than cognitive flexibility deficits.

RESUMO

Identifying factors that influence risk of dietary lapses (i.e., instances of dietary non-adherence) is important because lapses contribute to suboptimal weight loss outcomes. Existing research examining lapse risk factors has had methodological limitations, including retrospective recall biases, subjective operationalizations of lapse, and has investigated lapses among participants in gold-standard behavioral weight loss programs (which are not accessible to most Americans). The current study will address these limitations by being the first to prospectively assess several risk factors of lapse (objectively operationalized) in the context of a commercial mobile health (mHealth) intervention, a highly popular and accessible method of weight loss. N = 159 adults with overweight or obesity enrolled in an mHealth commercial weight loss program completed ecological momentary assessments (EMAs) of 15 risk factors and lapses (defined as exceeding a point target for a meal/snack) over a 2-week period. N = 9 participants were excluded due to low EMA compliance, resulting in a sample of N = 150. Dietary lapses were predicted by momentary increases in urges to deviate from one's eating plan (b = .55, p < .001), cravings (b = .55, p < .001), alcohol consumption (b = .51, p < .001), and tiredness (b = .19, p < .001), and decreases in confidence related to meeting dietary goals (b = -.21, p < .001) and planning food intake (b = -.15, p < .001). This study was among the first to identify prospective predictors of lapse in the context of a commercial mHealth weight loss program. Findings can inform mHealth weight loss programs, including just-in-time interventions that measure these risk factors, calculate when risk of lapse is high, and deliver momentary interventions to prevent lapses.

RESUMO

PURPOSE: Body dissatisfaction (BD) is supported as a maintenance factor for eating disorders (EDs) characterized by binge eating (BE). Although it is traditionally conceptualized as a trait construct, ecological momentary assessment (EMA) studies have shown that it fluctuates within-day and that momentary elevations in BD prospectively predict near-time ED behaviors. However, less is known about the contextual factors that precipitate these fluctuations in BD. METHODS: The current study thus sought to examine whether certain internal (i.e., negative affect, shape/weight-related cognitions) and environmental (i.e., attending social events, being exposed to thin-ideal media, spending time on social media) factors prospectively predict momentary elevations in BD in females with BE. Participants (n = 25) completed an EMA protocol over 14 days. RESULTS: Data on BD and internal and environmental factors were analyzed using generalized estimating equations. Results showed that (1) greater than one's usual negative affect and shape/weight-related cognitions, and (2) spending time on social media prospectively predicted momentary elevations in BD. Interestingly, attending social events prospectively predicted momentary reductions in BD. CONCLUSION: These findings may have important implications for conceptualizing and managing BD to prevent ED behaviors. LEVEL OF EVIDENCE: Level II, controlled trial without randomization.

RESUMO

OBJECTIVE: Automated digital interventions (ADIs) represent a potentially promising approach to enhance the outcomes of human coach-delivered weight loss interventions. However, the extent to which ADIs provide additive benefit is unclear. This study represents the first systematic review and meta-analysis of the effectiveness of ADIs for improving the outcomes of human coach-delivered weight loss treatment. METHOD: Electronic database searches were used to identify trials that compared differences in weight change between (a) weight loss interventions that were delivered exclusively by coaches and (b) interventions supplementing this same human coaching with an ADI. Subgroup and moderator analyses examined the influence of intervention duration, duration of human coach contact, presence of tailored coaching, modality of the ADI and demographic variables on ADI effectiveness outcomes. RESULTS: Thirteen studies met inclusion criteria (1,471 participants). Random-effects meta-analysis revealed a mean difference in weight change between conditions of 2.18 kg at postintervention, representing a medium effect size of .54 (95% CI [.13, .95]). Subgroup analyses suggested that lower duration of coach contact was associated with improved additive effectiveness of ADIs. No other subgroup differences were found. Publication bias appeared to be a potential concern, though high levels of heterogeneity and a small number of included studies likely limited the ability to infer its presence. CONCLUSIONS: Results support the use of ADIs to augment coach-delivered behavioral weight loss treatment, and also suggest that ADIs have the greatest impact when coaching is relatively low in frequency or duration.

RESUMO

Binge eating (BE) often develops during adolescence and is associated with deleterious psychological and physical consequences. Current treatments for adolescents achieve suboptimal results, likely due to failure to adequately address fear of weight gain (FOWG) which maintains BE. Thus, exposure treatment (the most powerful intervention for fear) may be a promising approach. However, exposure treatment has only minimally tested in adults with BE and never tested in adolescents. Thus, the current study is the first to evaluate a 4-session exposure module within a 12-session standard cognitive behavioral therapy for adolescents with BE. We recruited adolescents with BE (N = 5) and examined treatment feasibility, acceptability, and preliminary effects on FOWG and eating pathology. Overall, the 4-session exposure module was feasible and acceptable and showed preliminary evidence that it could reduce FOWG. However, several participants did not endorse significant fears of weight gain; rather, these participants reported that fears of deprivation or social judgment were more related to their BE. Future research should test higher doses of exposure and further examine the role of fear of deprivation/social judgment. Finally, future iterations of this treatment could include more parent involvement or test exposure in combination with treatments other than cognitive behavioral therapy, such as family-based treatment.

RESUMO

Caregivers and healthcare professionals (HPs) are increasingly concerned about childhood obesity. A critical consideration of caregivers and HPs is discussing weight status without provoking disordered eating. Given the complexity of these interacting concerns, major health advocacy groups have independently published guidelines for having conversations with children about overweight/obesity. The current investigation represented the first-ever systematic review of these guidelines to analyze their content, consistency, actionability, or scientific support. To conduct a systematic review, the authors performed a web-based search using the terms parent/HP, guidelines, child, and overweight/obesity that identified 59 guidelines on childhood obesity broadly, of which 13 provided explicit direction on how the caregiver or HP should approach a conversation about overweight with a child. Within these 13 guidelines, nine topic domains were identified: attitude modeling (covered by 31% of guidelines), behavior modeling (61%), dietary recommendations (54%), physical activity (46%), body acceptance and self-esteem (69%), conversation advice (92%), contact with HP (46%), talking about "weight" versus "overall health" (54%) and external factors (e.g., bullying, media) (54%). Although guidelines presented similar content, several inconsistencies in recommendations emerged. Notably, only three of the 13 guidelines referenced any scholarly sources and only a small minority of advice was actionable by caregivers or HPs. It is evident that guidelines for caregivers and HPs on speaking to children about obesity offer inconsistent advice, minimally based on empirical evidence. Future guidelines should aim to unify their messages for caregivers and HP and be better supported by empirical data.
