Disordered eating in ethnic minority adolescents with overweight

Association of psychological distress with health-related quality of life in Asian adolescents seeking obesity treatment

INTRODUCTION

There is limited research on the psychosocial health of Asian adolescents undergoing obesity treatment. Our study examined the predictors of psychological distress, disordered eating and poor health-related quality of life (HRQoL) in these adolescents and the associations between them.

METHODS

A total of 82 adolescents aged 11-17 years were recruited from the Weight Management Clinic in KK Women's and Children's Hospital between June 2022 and January 2023. Participants completed the following questionnaires: (a) Young Person's Clinical Outcomes in Routine Evaluation (YP-Core) assessing for psychological distress, (b) Children's Eating Attitude Test (ChEAT) evaluating for disordered eating behaviours, and (c) Pediatric Quality of Life Inventory (PedsQL) measuring HRQoL.

RESULTS

Participating adolescents had a mean body mass index of 31.9 ± 5.1 kg/m2. Of the participants, 40% reported significantly symptomatic psychological distress (YP-Core score ≥14) and 16% were at risk of eating disorders (ChEAT score ≥20). A higher YP-Core score was the only significant determinant of poorer HRQoL, after controlling for demographic variables and ChEAT scores. Malay (regression coefficient: 6.6, 95% confidence interval [CI]: 0.6-12.6, P = 0.031) and Indian (regression coefficient: 8.9, 95% CI: 3.8-14.0, P = 0.001) adolescents were more likely to report disordered eating and psychological distress, respectively, as compared to Chinese adolescents. Adolescents whose parent(s) had obesity (regression coefficient: 3.4, 95% CI: 0.1-6.7, P = 0.043) were also more likely to experience greater psychological distress.

CONCLUSION

Understanding the determinants of psychological distress, disordered eating and HRQoL will facilitate targeted screening and management of the psychosocial complications of adolescent obesity.

Disordered Eating in Pediatric Obesity

Children and youth with overweight and obesity are at an increased risk for the development of an eating disorder. Previous research has shown that disordered eating behaviors are prevalent in this population. Screening for disordered eating behaviors in children and youth with overweight and obesity is necessary to determine the course of the treatment. In children and youth with obesity and comorbid disordered eating behaviors, treatment should be multidisciplinary and include psychological, medical, nutrition, and physical activity care.

Bulimia Nervosa and Binge-Eating Disorder Across the Lifespan

This article aims to review the current evidence-based psychotherapy and psychopharmacological treatments for adults and youths with bulimia nervosa (BN) and binge-eating disorder (BED). Treatments for adults and for children and adolescents are discussed separately, including developmental considerations in the management of these disorders among youths. Although several evidence-based psychotherapy and psychopharmacological treatment options have been established for adults with BN or BED, there is much less empirical support for the management of these eating disorders among children and adolescents. This review concludes by discussing promising modalities and innovations, highlighting the potential utility of integrating technology into treatment approaches. Despite decades of treatment development and testing, a sizable proportion of individuals with BN or BED do not respond to the current evidence-based treatments, highlighting the need for continued research in these domains. Future research should focus on testing psychotherapy treatments among diverse samples in large, randomized controlled trials, as well as on treatments that can be easily scaled and implemented in community settings.

Medical Considerations and Consequences of Eating Disorders

Eating disorders may result in medical complications that affect every body system with both acute and chronic consequences. Although some medical complications may require acute medical hospitalization to manage, other complications, such as low bone mineral density, may not present until malnutrition has become chronic. It is critical for team members to be aware of the early clinical signs of malnutrition and disordered eating behaviors, as well as longer-term complications that may affect their patients. When identifying eating disorder concerns, appropriate colleagues from the medical, nutrition, and psychiatric fields can be engaged in order to collaborate on stabilizing and improving the health of patients.

Protective role of family mealtime frequency against disordered eating behaviors: Racial and ethnic differences

Family mealtimes have been recognized for their positive effect on child and adolescent health outcomes. Frequent family meals have been shown to have protective effects in reducing disordered eating behaviors, but the variability of these effects across different racial and ethnic backgrounds has been less explored. To address the gap, the current study utilizes a sample of 33,417 families with children (ages 6-17) in the United States who participated in the 2022 National Surveys of Children's Health (NSCH). Logistic regressions were conducted to examine the association between family mealtime frequency and the manifestation of disordered eating across youth from diverse racial/ethnic backgrounds. Our findings revealed that frequent family mealtimes are associated with a lower risk of engaging in disordered eating behaviors in youth. However, there were disparities in the associations between family mealtime frequency and the prevalence of disordered eating behaviors among children from different racial/ethnic backgrounds. Youth who never participated in family mealtimes were at a greater risk of engaging in disordered eating behaviors among those identifying as non-Hispanic Black or of 'other' racial groups. In youth identifying with multiple races, the frequency of family was not associated with the odds of disordered eating behaviors. The results provide insights into the nuanced influence of family mealtime frequency on disordered eating based on diverse racial/ethnic groups. This highlights the need for future studies to identify factors associated with racial/ethnic identities that may contribute to disordered eating behaviors in youth to identify the unique needs and challenges faced by families in leveraging the protective effect of family mealtimes.

The cost of the perfect body: influence mechanism of internalization of media appearance ideals on eating disorder tendencies in adolescents

BACKGROUND

Some studies have examined the relationship between internalization of media appearance ideals and eating disorders. However, few have discussed the relationship between eating disorder tendencies. To fill this research gap, this study was to explore the influencing mechanisms of internalization of media appearance ideals on adolescents' eating disorder tendencies in Chinese cultural context.

METHOD

The Sociocultural Attitudes Towards Appearance Questionnaire, Eating Attitude Test-26, Physical Self-Description Questionnaire, Body Image Depression Questionnaire and Multidimensional Scale of Perceived Social Support were employed in this study to investigate 1523 adolescents. The collected data were analyzed using SPSS 26.0 and AMOS 24.0.

RESULT

The results showed that: (1) internalization of media appearance ideals had a significant positive predictive effect on adolescents' eating disorder tendencies; (2) internalization of media appearance ideals significantly influenced adolescents' eating disorder tendencies through the mediating role of body esteem and body image disturbance respectively, and also influenced eating disorder tendencies through the chain mediating of both; and (3) social support played a moderating role between body image disturbance and eating disorder tendency.

CONCLUSION

Our findings suggest distinct pathways through which internalization of media appearance ideals may influence adolescents' eating disorder tendencies. It is suggested that reducing body image disturbance and enhancing social support can help reducing eating disorder tendency.

Examining clinicians' perceptions and experiences working with diverse families in family-based treatment: Common adaptations and considerations for treatment engagement

OBJECTIVE

Family-Based Treatment (FBT) is the leading manualized treatment for adolescent eating disorders; however, there is limited research on the adaptation of FBT for diverse families (i.e., families belonging to identity groups subject to systemic barriers and prejudices). The purpose of this qualitative study was to address: (1) adaptations made to the FBT model (if any) by clinicians working with diverse youth and families; (2) the barriers/facilitators of maintaining adherence (fidelity) to the model for these families; and, (3) the barriers/facilitators to access and engagement in FBT for diverse families.

METHOD

Forty-one FBT clinicians were recruited globally using purposive and snowball sampling, and listservs from eating disorder networks. Clinicians participated in individual interviews or focus groups, discussing their experiences delivering and adapting FBT for diverse families. Qualitative data was transcribed verbatim and analyzed using directed content analysis.

RESULTS

Some participants reported making adaptations to every phase of the FBT model, while others did not, when working with diverse families. In Phase 1, participants cited adapting the family meal, length/number of sessions provided, and addressed systemic barriers. In Phase 2, participants adapted the length of the phase and rate/level of independence given back to the adolescent. In Phase 3, participants increased or decreased the number of sessions, or eliminated this phase to address barriers to engagement in FBT.

DISCUSSION

This is the first study to qualitatively examine clinicians' experiences of implementing FBT with diverse families. Results may inform future FBT planning, clinician training, clinical decision-making tools, and opportunities for modifications to the foundational model.

PUBLIC SIGNIFICANCE

This qualitative study examined clinicians' perceptions and experiences implementing FBT with diverse families, specifically what adaptations (if any) were made to the foundational model, and the barriers and facilitators to adhering to and engaging in the model. Results show that some participants reported making adaptations to every phase of FBT, while others did not, with diverse families. Findings may inform future treatment planning, clinician training, clinical decision-making tools, and potential modifications to FBT.

Bias-based bullying, self-esteem, queer identity pride, and disordered eating behaviors among sexually and gender diverse adolescents

OBJECTIVE

Limited research incorporates an intersectional approach when evaluating disordered eating behaviors among those holding minoritized social positions, such as lesbian, gay, bisexual, queer, questioning, and/or transgender/gender diverse (LGBTQ) adolescents. The current study assessed stigma experiences from peers at school, self-esteem, LGBTQ pride, and overlapping social positions as they relate to disordered eating behaviors among LGBTQ adolescents.

METHOD

Participants included 11,083 adolescents (Mage  = 15.6, SD = 1.3; 34.8% transgender/gender diverse) from a large national survey study of LGBTQ adolescents from 2017. Exhaustive Chi-square Automatic Interaction Detection analysis was used to identify bias-based bullying experiences (i.e., weight-based, identity-based), self-esteem, LGBTQ pride, and overlapping social positions (i.e., gender identity, sexual identity, race/ethnicity, body mass index (BMI) percentile) associated with the highest prevalence of unhealthy weight control behaviors, extreme unhealthy weight control behaviors, and past year binge eating.

RESULTS

Adolescents in the 28 identified groups with a high prevalence of disordered eating behavior held at least one structurally marginalized social position (e.g., high BMI), bias-based bullying experience, low self-esteem, or low LGBTQ pride in addition to being LGBTQ. Weight-based bullying was a salient risk-factor for disordered eating across social positions. Among adolescents with the same social positions, levels of self-esteem, LGBTQ pride, but no bias-based bullying experience, prevalence estimates of disordered eating were, on average, 23% lower.

DISCUSSION

LGBTQ adolescents with multiple marginalized social positions and related factors engage in disproportionately high prevalence disordered eating. Findings underscore the importance of addressing intersecting experiences of stigma to reduce disordered eating and promote health equity among adolescents.

PUBLIC SIGNIFICANCE

Multiply marginalized LGBTQ adolescents, most of whom also reported experiencing bias-based bullying from peers at school, reported disproportionately high prevalence disordered eating. In comparison groups of adolescents with no bias-based bullying experience, prevalence of disordered eating was, on average, 24% lower. Findings underscore the importance of addressing intersecting experiences of stigma to reduce disordered eating and promote health equity among adolescents.

Parent involvement approach and changes in eating pathology within an adolescent obesity intervention

BACKGROUND

Although adolescents with obesity have heightened risk for eating pathology, the impact of differential parent involvement on eating pathology after obesity treatment is unknown. We examined differences in eating pathology in adolescents whose parents were randomized to distinct interventions within adolescent obesity treatment.

METHODS

Participants were 82 adolescent/parent dyads (adolescents: 63 % female; 55 % racial/ethnically marginalized) enrolled in TEENS+, a 4-month behavioral weight loss intervention. Parents were randomized to either a parent weight loss treatment (TEENS+PWL) or parent skills training (TEENS+PAC). Adolescents completed the Eating Disorder Examination-Questionnaire with Instructions (EDE-Q-I) and Child Depression Inventory (CDI) at baseline, 4 m, and 7 m. Group differences in eating pathology (global score; eating concern, weight concern, shape concern, restraint) and depression across time points were evaluated with linear mixed models.

RESULTS

No significant differences were observed between TEENS+PAC and TEENS+PWL in eating pathology or depression, nor were there group by time interactions. Time point differences were observed for all EDE-Q-I and CDI outcomes, except eating concerns; pairwise contrasts revealed a variety of change patterns. Weight and shape concerns decreased from 0 to 4 m; observed reductions were maintained at 7 m. Restraint was highest at 4 m and decreased at 7 m but did not return to baseline. EDE-Q-I global scores significantly declined over time. Depression decreased over time, but a significant difference was only observed between 0 and 7 m.

CONCLUSIONS

Neither parent intervention yields harm related to eating pathology in adolescents engaged in obesity treatment. Obesity treatment does not appear to have iatrogenic effects on eating pathology in adolescents.

Disordered Eating and Eating Disorders in Pediatric Obesity: Assessment and Next Steps

While the exact prevalence of disordered eating in youth who are overweight and have obesity has not been determined, studies show that the odds of a young adult (18-24 years) with obesity engaging in disordered eating behaviors is 2.45 times more likely to occur than in young adults with Body Mass Indexes (BMI) in the normative range. The purpose of this review is to highlight the role that disordered eating and eating disorders may play in pediatric obesity and the importance of screening for these conditions. The ability to identify and assess disordered eating alters the course of treatment. Without an understanding of the intersection of obesity and disordered eating, medical providers may continue treatment-as-usual. Doing so may inadvertently contribute to internalized weight bias in patients with obesity and exacerbate their disordered eating symptoms and behaviors. In addition, understanding the spectrum of disordered eating in pediatric patients with obesity allows providers to tailor treatments, discuss food and physical activity differently, and know when to refer patients to eating-disorder-specific providers for continued treatment.

Eating Disorders in Youth with Chronic Health Conditions: Clinical Strategies for Early Recognition and Prevention

Youth with chronic health conditions face an elevated risk of eating disorders and disordered eating behaviors. Contributors to this phenomenon may include the unique threats faced by this vulnerable population to their body image, their relationships with food and eating, and their mental health and self-esteem. However, youth with chronic health conditions may also experience more severe medical complications and mortality from eating disorder behaviors because of the additional risks conveyed by their underlying conditions. In this review, clinical strategies are provided to support youth with chronic health conditions through early recognition of eating disorder behaviors and prompt referral to treatment, which is important for a better prognosis. Suggestions are also given to mitigate their risk of developing eating disorders by proactively addressing risk factors and offering thoughtful anticipatory guidance that promotes a positive relationship with food and eating.

Weight and disordered eating among adolescents from low-income backgrounds

Disordered eating affects youth from varying socioeconomic backgrounds; however, representation of youth from low-income backgrounds within disordered eating research has been limited. The aim of the current study was to examine the association between adolescent weight and disordered eating among a sample of youth from a low-income background and to examine specific socioenvironmental factors that might moderate this association. Adolescents ages 12-17 (N = 73) from a low-income background and their parents/guardians completed self-report questionnaires. Adolescent height and weight were objectively measured to calculate BMI z-score. Adolescent weight was significantly positively associated with global disordered eating (95 % CI [0.26, 0.54]), after controlling for sex. Parental weight concern moderated the association between weight and global disordered eating, F(4, 68) = 18.44, p < .01, such that the relation between adolescent zBMI and disordered eating was no longer significant at low levels of parental weight concern. Structured family meals moderated the association between weight and global disordered eating, F(4, 68) = 11.99, p < .01, such that more frequent meals weakened the association between adolescent zBMI and disordered eating. Findings suggest that higher weight is associated with greater levels of disordered eating among adolescents from a low-income background. In addition, lower levels of parental weight concern and more frequent family meals significantly buffered the association between weight and disordered eating in this at-risk, yet understudied population. Both parental weight concern and family meals present as factors within the family environment that may serve as targets for intervention.

An exploration of the association between premorbid weight status on patient and caregiver factors at pre and post-treatment among youth with anorexia nervosa/atypical anorexia nervosa

Patients with atypical anorexia nervosa (AAN) or anorexia nervosa (AN) with premorbid history of higher weight (PHW; median BMI ≥ 85th %ile) may report greater eating disorder (ED) pathology, anxiety, and depression, than patients with premorbid history of lower weight (PLW; mBMI <85th %ile). Less is known about caregiver attitudes or treatment outcome related to premorbid weight history. The current study examined associations between premorbid weight history and patient/caregiver factors at presentation, during treatment, and end of treatment among adolescents (N = 138) diagnosed with AN/AAN and their caregivers who received interdisciplinary ED treatment. The sample comprised adolescents with PHW (n = 58, 40.6 %) or PLW (n = 82, 59.4 %). Adolescents with PHW did not differ with regard to patient- or caregiver-reported ED symptoms, comorbid psychopathology, rates of treatment completion, and attainment of estimated body weight compared to PLW (ps > .05). Adolescents with PHW (vs. PLW) were more likely to be diagnosed with AAN (67.9 %, p < .001), identify as cisgender male (p < .001) and to have lost more weight prior to presentation (p < .001). Perceived caregiver burden was lower among adolescents with PHW vs. PLW (p < .001). Further research should expand on this preliminary study exploring associations between premorbid weight history on patient and caregiver factors at treatment presentation and conclusion to enhance the efficacy of evidence-based treatment across the weight-spectrum.

Interoceptive deficits moderate the relationship between bulimia symptoms and suicide risk

Objective: Interoceptive deficits have been linked to suicidality and eating disorders. The relationship between disordered eating symptoms and suicidality may depend on the level of interoceptive deficits. It was expected that interoceptive deficits would moderate the relationship between disordered eating symptoms (oral control, dieting, and bulimia) and suicidality (suicide attempts, ideation, and communication) when interoceptive deficits were high. Methods: University students (N = 417, Mage = 19.75, 78.2% white, 72.4% female) completed self-report measures that assessed disordered eating, interoceptive deficits, and suicide history. Results: Interoceptive deficits emerged as a significant moderator only in the association between bulimia symptoms and suicidality, when interoceptive deficits were high. Conclusions: The results of this study indicate that bulimia symptoms may have a unique interaction with interoceptive deficits and suicidality. Future research should focus on targeting interoceptive deficits in treatment to help reduce disordered eating symptoms and suicide risk, particularly for students with bulimia symptoms.

Socioeconomic status and eating disorder prevalence: at the intersections of gender identity, sexual orientation, and race/ethnicity

BACKGROUND

Longstanding biases have fostered the erroneous notion that only those of higher socioeconomic status (SES) experience eating disorders (EDs); however, EDs present across all SES strata. Considering the dearth of ED research among those of lower SES, this study examined (1) the overall association between SES and ED prevalence, and (2) ED prevalence in the context of four relevant social identities (i.e. SES, gender identity, sexual orientation, and race/ethnicity) from an intersectional perspective, as unique combinations of multiple social identities may differentially influence risk.

METHODS

A sample of 120 891 undergraduate/graduate students from the Healthy Minds Study self-reported family SES with a single-item question, gender identity, sexual orientation, and race/ethnicity, and were screened for ED risk.

RESULTS

Participants of lower SES had 1.27 (95% CI 1.25-1.30) times greater prevalence of a positive ED screen than those of higher SES. Substantial heterogeneity was observed across the four social identities beyond the association with SES. For example, positive ED screens were particularly common among lower SES, Latinx, sexual minority cisgender men and women, with 52% of bisexual men and 52% of lesbian women of Latinx ethnicity and lower SES screening positive.

CONCLUSIONS

Although positive ED screens were more common among undergraduate/graduate students of lower SES, the particularly high ED risk reported by certain groups of lower SES with multiple minority identities reinforces the importance of investigating multi-layered constructs of identity when identifying groups at disproportionate risk.

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).

Flames of transformation: Igniting better mental and physical health for racialized and gendered North Americans

COVID-19 is catalyzing both crises and opportunities for communities of color. The crisis of high mental and physical morbidities and mortalities exposes persistent inequities while providing opportunities to celebrate the power of rejuvenated anti-racism movements, fueled partly in response to the extremism of ultra-conservative governments, the circumstances to reflect deeply on racism because of forced stay-at-home-orders, and digital technologies primarily driven by youth. In marking this historical moment of longstanding anti-racism and decolonial struggles, I assert the importance of foregrounding women's needs. In analyzing racism, rooted in colonialism and white supremacy, and its impacts on mental and physical health status, I focus on improving racialized women's lives within the larger context, concentrating on the determinants of health. I contend that fanning the flames to scathe the racist and sexist foundations of North American society will break new ground for sharing wealth, bolstering solidarity and sisterhood, and ultimately improving Black, Indigenous, and Women of Color (BIWOC) health. Canadian BIWOC earn approximately 59 cents to the dollar earned by non-racialized men, creating vulnerabilities to economic downturns, such as the one Canada is currently in. BIWOC care aides, at the bottom of the healthcare hierarchy, are emblematic of other Black, Indigenous, and People of Color (BIPOC), who face risks of frontline work, low wages, poor job security, unpaid sick days and so forth. To that end, policy recommendations include employment equity initiatives that hire groups of racialized women who consciously express solidarity with each other. Cultural shifts within institutions will be key to providing safe environments. Improving food security, internet access and BIWOC-related data collection linked to community-based programming while prioritizing research on BIWOC will go a long way toward improving BIWOC health. Addressing racism and sexism within the healthcare system, aiming for equitable diagnostic and treatment foci, will require transformative efforts including determined leadership and buy-in from all levels of staff, long-term training and evaluation programs, audited by BIPOC communities.

Legal Evolution of a Law Against Weight Discrimination in the United States: A Focus on Massachusetts

Weight discrimination heightens health inequalities, particularly among racial and ethnically diverse populations. We aim to research the legal evolution of the law against weight discrimination (S.2495) and raise awareness among lawmakers in the Commonwealth of Massachusetts. We invited officials (n = 199) to attend a legislative briefing, and 25.6% completed a 14-question anonymous survey upon arrival. Contrary to our hypothesis, this first-of-its-kind study found that most policymakers are aware of weight biases. While S.2495 did not pass, the current bill S.2669, prohibiting body size discrimination, has recently been reported favorably by the Joint Committee on the Judiciary and referred to the committee on Senate Ways and Means.

Risk factors for eating disorders: findings from a rapid review

BACKGROUND

Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid Review aimed to identify and summarise research studies conducted within the last 12 years, focusing on risk factors associated with eating disorders.

METHODS

The current review forms part of a series of Rapid Reviews to be published in a special issue in the Journal of Eating Disorders, funded by the Australian Government to inform the development of the National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2021, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, or population studies). Data pertaining to risk factors for eating disorders were synthesised and outlined in the current paper.

RESULTS

A total of 284 studies were included. The findings were divided into nine main categories: (1) genetics, (2) gastrointestinal microbiota and autoimmune reactions, (3) childhood and early adolescent exposures, (4) personality traits and comorbid mental health conditions, (5) gender, (6) socio-economic status, (7) ethnic minority, (8) body image and social influence, and (9) elite sports. A substantial amount of research exists supporting the role of inherited genetic risk in the development of eating disorders, with biological risk factors, such as the role of gut microbiota in dysregulation of appetite, an area of emerging evidence. Abuse, trauma and childhood obesity are strongly linked to eating disorders, however less conclusive evidence exists regarding developmental factors such as role of in-utero exposure to hormones. Comorbidities between eating disorders and mental health disorders, including personality and mood disorders, have been found to increase the severity of eating disorder symptomatology. Higher education attainment, body image-related factors, and use of appearance-focused social media are also associated with increased risk of eating disorder symptoms.

CONCLUSION

Eating disorders are associated with multiple risk factors. An extensive amount of research has been conducted in the field; however, further studies are required to assess the causal nature of the risk factors identified in the current review. This will assist in understanding the sequelae of eating disorder development and in turn allow for enhancement of existing interventions and ultimately improved outcomes for individuals.

Racial and Ethnic Disparities in Weight Loss Behaviors Among US College Students

Purpose

Weight loss behaviors are prevalent among college students and are associated with adverse physical and psychological outcomes, such as an elevated risk of developing an eating disorder. While cross-ethnic differences have been reported, no consistent pattern has emerged. The purpose of this study was to examine racial and ethnic differences in weight loss behaviors among female and male college students.

Patients and Methods

The American College Health Association-National College Health Assessment (ACHA-NCHA) II-C survey data from the collection periods from 2015 to 2019 was used. A total of 426,425 students participated in the survey. Most participants were White (60%) and female (68.5%). Information on students' age, body mass index (BMI), and self-rated health was also collected. Logistic regression analyses were performed to determine cross-ethnic differences in weight loss methods among female and male students.

Results

Students' weight loss behaviors were assessed and included dieting, exercising, vomiting or taking laxatives, and the use of diet pills in the past 30 days. More than half of the participants attempted to lose weight through exercise (53.5%), and 40.3% of students dieted to lose weight in the past month. Purging and the use of diet pills were endorsed by 2.9% and 2.8% of the participants, respectively. With few exceptions, male students from racial and ethnic minority backgrounds were more likely to engage in extreme weight control practices (ie, vomiting or taking laxatives, taking diet pills) than White male students, while female students from racial and ethnic minority backgrounds were less likely to use diet and exercise as weight loss methods than White female students. For all outcomes, Biracial/Multiracial and Hispanic/Latino male students were more likely to attempt weight loss than White male students. Biracial/Multiracial female students more frequently endorsed extreme weight control behaviors than White female students.

Conclusion

The results of the present study add to the growing body of literature on the relationship between race and ethnicity and weight loss behaviors. The findings indicate the need for tailored educational and intervention programs on college campuses.

Measuring adolescents' eating in the absence of hunger in the home environment using subjective and objective measures

Eating in the absence of hunger (EAH) has been identified as a behavioral phenotype for obesity. Few studies have reported on objective measures of EAH in adolescents, and fewer yet have objectively measured EAH in a naturalistic, home setting. The purpose of this paper was to examine relations between objective, adolescent-report and parent-report measures of EAH, and to examine variation by sex and race. Participants included 295 predominantly low-income and rural adolescents (mean age = 14.2 ± 0.6 years) and their parents, drawn from the Family Life Project. An EAH task was administered in the home following an ad-libitum meal and compulsory milkshake; EAH was also reported on a web-based survey (both adolescent and parent reports) and adolescents' BMIz was calculated from height and weight, measured in the home or self-reported on the web survey. A high degree of variability in EAH intake was observed (range = 8-741 kcals). Parent and adolescent reports of EAH were weakly correlated and unrelated to observed EAH consumption; only adolescent reports of EAH were related to their BMIz. Several relations varied by sex and race. Positive associations between reported and observed EAH was only observed in girls, and positive associations between observed EAH and BMI was only observed in boys and in white adolescents. Overall EAH consumption was significantly greater in boys and in white adolescents. These findings suggest that EAH can be measured in adolescents in the home. In this sample of youth experiencing rural poverty, this home-based measure appears most valid for white adolescent girls.

Weight Concerns in Black Youth: The Role of Body Mass Index, Gender, and Sociocultural Factors

Weight concerns are prevalent among Black adolescents and have negative ramifications for well-being. We examined racial identity and racial socialization as potential sociocultural resources that might mitigate the development of weight concerns among Black adolescents, and we evaluated gender differences in these links. Participants were 132 Black youth (45% female; M age = 14.33 years at Time 1) who completed two annual home interviews. Results revealed that for adolescents with high (but not low) body mass indices (BMI), racial identity may be protective against developing weight concerns. Further, fathers' (but not mothers') racial socialization was protective against weight concerns for girls with high BMI. Findings highlight the importance of sociocultural contexts toward refining theory and advancing evidence-based practice.

Development and validation of a measure of curvy ideals internalization

Several sociocultural female body ideals exist - thin, muscular/athletic, and, more recently, curvier ideals, which research specifically suggests are more prevalent among Black women. Two validated measures assess women's desire for curvier bodies, but neither assess certain facets of curvy ideals (e.g., thick vs. slim-thick) separately. We developed and validated the Curvy Ideals Internalization (CII) Scale, to be used alone or alongside existing measures of appearance ideal internalization. Focus groups among racially/ethnically diverse women informed initial items. A sample of 897 White (37.1%), Black (34.2%), and biracial Black and White (28.7%) U.S. women completed the initial 37-item CII to determine factor structure, narrow the item pool, and examine validity and reliability. A separate sample (N = 366) of U.S. Black, White, and biracial women completed the CII to confirm the factor structure. The final CII has eleven items, with factors assessing thick/curvy ideal internalization and facets of slim-thick ideal internalization: thin waist and large breast size. The CII has adequate internal consistency, test-retest reliability, construct validity, and factorial validity. The CII is appropriate for use among Black, White, and biracial women to assess internalization of curvier body ideals and needs to be validated in more diverse samples.

Update on the epidemiology and treatment of eating disorders among Hispanic/Latinx Americans in the United States

PURPOSE OF REVIEW

This review provides a 6-year update on the prevalence and treatment of eating disorders among Hispanic/Latinx Americans in the United States.

RECENT FINDINGS

Prevalence of eating disorders tends to be lower in Hispanic/Latinx American adolescents and adults relative to non-Hispanic White peers. Numerous risk factors for disordered eating symptoms have been identified, including negative body image, depression, sexual assault and culturally specific risk factors, including ethnic discrimination and acculturative stress. Hispanic/Latinx individuals seek treatment less often with the most influential barriers being cost of treatment, eating disorder stigma, eating disorder shame and mental health shame in general. Limited research on the treatment for eating disorders continue to persist. Culturally adapted cognitive behavioural therapy yielded similar outcomes to traditional cognitive behaviour therapy and had better treatment adherence and retention rates.

SUMMARY

The medical and sociopolitical climate of the United States has changed significantly since our previous review. The need for research on the effectiveness of eating disorder treatments for Hispanic/Latinx Americans remains important for one of the fastest growing populations in the U.S.

Experiencing Household Food Insecurity During Adolescence Predicts Disordered Eating and Elevated Body Mass Index 8 Years Later

PURPOSE

Growing evidence indicates that experiencing household food insecurity during adolescence is associated with disordered eating and elevated body mass index (BMI). However, little is known about the temporal nature of these relationships. The current longitudinal study examined how adolescent experiences of household food insecurity are related to disordered eating and weight status 8 years later.

METHODS

A population-based sample of ethnically/racially and socioeconomically diverse participants (n = 1,340) were surveyed as adolescents (mean age = 14.5 years) and as young adults (mean age = 22.0 years). Parents/caregivers completed the six-item U.S. Household Food Security Survey Module at baseline.

RESULTS

Household food insecurity was common at baseline (37.8% of sample). In analyses adjusted for ethnicity/race and parental education, adolescent food insecurity longitudinally predicted a higher new onset of binge eating (food insecure: 21.3% vs. food secure: 16.2%, p = .038) and BMI ≥30 kg/m² (food insecure: 15.9% vs. food secure: 11.0%, p = .024), but not unhealthy weight control behaviors in young adulthood. The majority of adolescents with unhealthy weight control behaviors and elevated BMI still had these problems in young adulthood, but persistence was not associated with adolescent household food insecurity for any outcome.

DISCUSSION

Results of this longitudinal study suggest that household food insecurity during adolescence is a risk factor for disordered eating and elevated BMI in young adulthood, highlighting a need to comprehensively address these intersecting problems.

A Network Analysis Investigation of Disordered Eating Across Demographic and Developmental Subpopulations Using a National Epidemiological Sample of High School Students

Disordered eating (DE) poses a large societal burden, yet limited research has examined DE from a developmental epidemiological perspective. It is important to consider how demographics influence DE symptoms to inform prevention and early intervention programs across diverse subpopulations. Therefore, we conducted network analyses using a large nationally representative epidemiological sample of high school students (Youth Risk Behavior Survey, United States; n = 59,582) to identify the most important symptoms and symptom relationships among six DE behaviors. We compared networks by sex, grade, and race to identify differences in symptom networks. Dieting for weight loss was highly central across networks. Networks significantly differed across sex, grade, and race. Our results suggest that dieting for weight loss may be an early intervention target for eating disorders, regardless of demographic and developmental factors. In addition, sex, race, and age should be accounted for when researching and developing prevention programs for DE and eating disorders. Public health officials, as well as mental health professionals, should present a more balanced message about dieting and weight loss to high school students to prevent the detrimental impact of DE on physical and mental health. Notably, this study is the first large, nationwide epidemiological sample using DE symptoms in network analysis.

Eating Disorder Examination-Questionnaire: Evaluating factor structures and establishing measurement invariance with Asian/Hawaiian/Pacific Islander, Black, and White American college men

OBJECTIVE

This study evaluated the factor structure and invariance of the Eating Disorder Examination-Questionnaire (EDE-Q) in a sample of Asian/Hawaiian/Pacific Islander (n = 163), Black (n = 155), and White (n = 367) American university men.

METHOD

Twelve different EDE-Q factor structures reported in the literature were evaluated using multi-group confirmatory factor analyses, and measurement invariance assessed.

RESULTS

A respecified four-factor structure proposed by Parker et al. (2016) showed superior fit and was invariant across groups. Significant differences emerged across all latent factors, with small to medium effects. Asian/Hawaiian/Pacific Islander men reported significantly higher scores on factors assessing Appearance Concern, Overvaluation of Shape/Weight, and Eating Concerns, and were more likely to endorse regular objective binge eating (OBE) and fasting episodes than their Black and White peers. Both White and Asian/Hawaiian/Pacific Islander men reported greater dietary restraint than Black men. Among this sample, frequencies of regular compensatory exercise ranged from 10% to 16%, fasting 6% to 14%, and OBEs 1% to 10%.

DISCUSSION

Results provide further support for the use of alternate EDE-Q factor structures, especially among non-White men. In this study, Asian/Hawaiian/Pacific Islander men reported the highest levels of ED psychopathology relative to White and Black men, indicating they might be particularly vulnerable to EDs.

PUBLIC SIGNIFICANCE

This study failed to find support for using the original Eating Disorder Examination-Questionnaire four-factor structure to detect disordered eating in Asian, Black, and White American college men. An alternate model proposed by Parker et al. in 2016 may be more appropriate. Asian men also reported the highest levels of eating psychopathology relative to their peers, suggesting they may be at high risk for developing eating disorders.

Testing of a model for risk factors for eating disorders and higher weight among emerging adults: Baseline evaluation

Although a range of risk factors have been identified for disordered eating and weight status, the breadth of risk factors have been rarely considered within a single, comprehensive model. The robustness of these findings across countries also remains an open question. The present study sampled 6272 participants aged 18-30 years from eight countries in an attempt to evaluate combined and unique predictors for these two conditions, and to explore possible cross-country differences in these models. Participants completed a range of demographic, biological, behavioral, psychological, and sociocultural measures to test a comprehensive model of the contributions of these predictors for disordered eating and weight-related constructs (binge eating, body mass index, compensatory behaviors, dietary restraint, drive for muscularity, and drive for leanness). Structural invariance testing within a multigroup path analysis framework revealed that a single model across the eight countries provided poor model fit. Freeing of 22% of parameters across countries provided excellent fit and a satisfactory compromise for country-invariant and country-variant parameters in the model. Overall, predictors accounted for between 15% and 60% of variance in the outcome measures, with lowest explained variance for the disordered eating outcomes. Significant unique contributions to prediction were observed for each of the five risk factor variable types and across the eight countries. Thus, the findings show strong support for this model as an explanatory framework of both disordered eating and weight status.

Weight teasing experienced during adolescence and young adulthood: Cross-sectional and longitudinal associations with disordered eating behaviors in an ethnically/racially and socioeconomically diverse sample

OBJECTIVE

This study assessed cross-sectional and longitudinal relationships between weight teasing and disordered eating in an ethnically/racially and socioeconomically diverse sample of young people and examined these relationships across sociodemographic characteristics.

METHOD

The EAT 2010-2018 study surveyed adolescents (n = 1,534) in the Minneapolis/St. Paul public schools (mean age = 14.4 years) and 8 years later (mean age = 22.2 years).

RESULTS

Weight teasing was prevalent in adolescence (34.1%) and young adulthood (41.5%). In analyses adjusted for sociodemographic characteristics and body mass index, weight teasing was cross-sectionally associated with a higher prevalence of all disordered eating behaviors during both adolescence and young adulthood. For example, 64.5% of young adults who reported being teased about their weight engaged in unhealthy weight control behaviors, compared with 47.9% among those not teased (p < .001). There were fewer observed associations in longitudinal analyses, although weight teasing still predicted prevalent overeating and both prevalent and incident dieting (incident dieting-teased: 48.4% vs. not teased: 38.0%, p = .016). Weight teasing and disordered eating were more prevalent among Black, Indigenous, and People of Color (BIPOC) young people and those from low socioeconomic backgrounds, and the relationship between weight teasing and disordered eating was similar across ethnic/racial, socioeconomic, and gender demographic groups.

DISCUSSION

Results indicate that weight teasing is strongly correlated with disordered eating in both adolescence and young adulthood regardless of ethnicity/race, socioeconomic status, or gender. Finding suggest that future research and policy interventions should address weight stigma and prioritize the needs of BIPOC young people and young people from low socioeconomic backgrounds.

Dieting and substance use among White and Black adolescent girls

OBJECTIVE

Previous research has found an increasing co-occurrence of dieting and substance use behavior among adolescent girls. However, to date few studies have examined the temporal ordering of these behaviors. Further, limited research has been conducted to explore whether the pathways are similar among both White and Black girls.

METHOD

For the current study 1580 girls (grade 6-11; 78.2% White; 21.8% Black) provided data on their dieting behavior and substance use. A cross-lagged panel design was used to examine the concurrent and prospective relationship between dieting behavior and substance use across one year, then by race.

RESULTS

Among the full sample of girls, there was a significant concurrent relationship. Additionally, dieting behavior predicted substance use one year later, but the inverse relationship was not found. For the stratified analysis, dieting behavior and substance use were not correlated among Black girls at either time point, however concurrent relationships were found for White girls. For the prospective pathways non-significant effects were found for both groups.

DISCUSSION

These findings provide support for a temporal relationship between dieting behavior and substance use, such that the former predicts risk for the latter. However, when examined by race, some pathways of the full sample were found for White girls, whereas Black girls did not report an association between study variables. Thus, future studies should consider the impact of race within risk pathways.

Examining the impact of perceived weight discrimination on reported eating and exercise among White and Latino/a adults

A large body of research suggests that, among White individuals, perceived weight discrimination has deleterious consequences for eating and exercise outcomes; however, the research literature on perceived weight discrimination among other racial/ethnic groups is limited. The primary goal of the present study was to examine the associations of perceived weight discrimination with eating and exercise thoughts and behaviors among White versus Latino/a participants. A sample of White (N = 50) and Latino/a (N = 281) undergraduate college students with higher body weight (BMI: M = 30.65, SD = 5.42) completed self-report measures assessing perceived weight-based discrimination, frequency of intake of unhealthy and healthy foods, and frequency of both thoughts about exercise and exercise behaviors; we examined relationships among these variables within White versus Latino/a participants. Results showed that perceived weight discrimination was associated with more frequent intake of unhealthy foods, more frequent exercise thoughts, and less frequent exercise behaviors among White participants, and that there were no significant associations between perceived weight discrimination and the eating and exercise measures of interest among Latino/a participants. These findings highlight a number of potential avenues for future research to identify the mechanisms underlying these differential associations of perceived weight discrimination to eating and exercise behaviors across racial/ethnic groups.

A primary care modification of family-based treatment for adolescent restrictive eating disorders

Although eating disorders pose a significant threat to the health and well-being of children and adolescents, due to a profound scarcity of specialty providers, only a small percentage of patients receives evidence-based treatment. To improve access to care for restrictive eating disorders, we developed a modified version of Family-Based Treatment to be delivered by primary care providers (PCPs) and conducted a pilot study to evaluate the feasibility and preliminary outcomes of this intervention. Fifteen adolescents (mean age = 15.5 years) with restrictive eating disorders and their caregiver(s) were enrolled in Family-Based Treatment for Primary Care (FBT-PC), delivered by three trained PCPs. Retention for the intervention was high (n = 13, 86.7%). Over the course of 3 months, participants attended an average of 9.2 (SD = 2.8) sessions and experienced a significant increase in BMI percentile from 39.1 to 54.8 (t (13) = -6.71, p < .001; d = .61). FBT-PC appears to be feasible for implementation in the primary care setting and has the potential to improve access to treatment and yield positive outcomes for young patients with restrictive eating disorders.

Personal, proxy, and collective food agency among early adolescents

Early adolescence is a critical time for health behavior development because agency increases during the transition from childhood to adolescence. This qualitative study sought to identify how early adolescent participants described food-related agency. One-on-one interviews were conducted with 30 early adolescents (10-13 years). Data analysis was guided by Bandura's three modes of agency: personal, proxy, and collective. Results suggest participants' food behaviors were informed by a growing knowledge about nutrition, household food rules, and school food environments. Participants described different modes of agency in four areas - grocery shopping, cooking, consumption decisions, and nutrition information seeking - with varying degrees of agency in each area. Understanding how each of the three modes operate and the interplay between them can information future research aimed at improving the nutrition behaviors of early adolescents.

Addressing Disparities in Adolescent Eating Disorders: A Case Report of Family-Based Treatment in Primary Care

Eating disorders typically have a protracted course, marked by significant morbidity. Male adolescents and adolescents of color are at risk of delayed care. Primary care providers are well-positioned to identify eating disorders early and initiate treatment. This case report describes an adaptation of Family-Based Treatment delivered by a primary care provider to an Asian-American male adolescent from an immigrant family with restrictive anorexia nervosa. The adolescent achieved full-weight restoration and remission of his anorexia through treatment in primary care. Embedding eating disorder treatment within primary care could improve detection, engagement, and retention in treatment among young people from diverse backgrounds.

Eating disorder prevalence among multiracial US undergraduate and graduate students: Is multiracial risk different than the sum of each identity?

The number of individuals identifying as multiracial in the United States (US) has significantly increased in the past few decades, yet they are rarely the focus of study in eating disorders (ED) research. The current study is among the first to examine prevalence estimates of ED pathology across several distinct multiracial groups, to contrast prevalence estimates of ED pathology in each multiracial group with those among the corresponding monoracial identities, and to investigate these findings intersectionally with gender identity. Data from 145,379 US students, 11,433 of whom were multiracial, were collected from 199 US colleges and universities participating in the Healthy Minds Study between 2014 and 2019. Elevated ED pathology was defined as a score ≥ 2 on the SCOFF. Multiracial individuals identifying as American Indian/Alaskan Native and Hispanic/Latinx exhibited the highest prevalence estimates of elevated ED pathology (41.4% compared to 23.5% in the full sample). This group, as well as some other doubly marginalized groups (African American/Black and Hispanic/Latinx; African American/Black and Asian American/Asian), exhibited higher prevalence of elevated ED pathology than expected based on the observed prevalence estimates in their corresponding monoracial groups. Across gender identities, greater than expected prevalence estimates of elevated ED pathology were observed among multiracial individuals identifying as African American/Black and White and lower than expected prevalence estimates were observed among multiracial individuals identifying as Middle Eastern/Arab/Arab American and White. These results have important implications for understanding ED pathology in multiracial individuals and should inform intervention and treatment efforts to support individuals from these underserved groups.

Disordered eating among Arab and Jewish youth in Israel: the role of eating dinner with the family

Background

Disordered eating (DE), defined as unhealthy eating attitudes and behaviors, is considered a major public health problem among adolescents. Nevertheless, rates of DE among Arab and Jewish adolescents in Israel are still unknown. Furthermore, while previous studies have highlighted the role of frequent family meals as a protective factor against DE, studies examining home family dinners relative to other common dinner options (e.g., eating at home alone, eating out of the home, not eating dinner at all) are largely unavailable. We sought to use representative data of middle and high-school children in Israel in order to identify rates of DE among Arabs and Jews, while examining the relations of home family dinners (vs. other dinner options) with DE.

Methods

A nationally representative school-based survey of 4926 middle and high-school children (11–19 years old) was conducted during 2015–2016. Participants indicated where and with whom they had eaten dinner the day before. The 5-item SCOFF questionnaire was used (> 2 affirmative items were considered a likely case of DE). Height and weight were measured by personnel.

Results

DE was more prevalent among girls (29.7%) relative to boys (12.2%), Arabs (25.1%) relative to Jews (19.5%), and older (25.3%) relative to younger (17.6%) adolescents. Arabs were more likely to eat dinner at home with parents/family (chi² = 10.75, p = .001), or not to eat dinner at all (chi² = 63.27, p < .001), while Jews were more likely to eat dinner alone (chi² = 5.37, p = .021) or to eat dinner out of the home (chi² = 67.65, p < .001). Logistic regressions (stratified by ethnicity and adjusted for gender, age, weight) revealed that family dinners acted as a protective factor against DE, relative to eating out of the home or relative to not eating dinner at all among both ethnic groups, and relative to eating dinner alone among Arabs.

Conclusion

There are differences between Arab and Jewish adolescents in terms of rates of yesterday’s family dinners and DE. Given that eating dinner with the family was linked with lower rates of DE, possible interventions to reduce DE may include educating parents of both Arab and Jewish adolescents regarding the importance of family meals.

Hygiene and Eating Healthy Habits and Practices in Spanish Families with Children Aged 6 to 14

During childhood and pre-adolescence, the family environment is key to initiating and consolidating healthy styles in children through a balanced diet and basic hygiene habits. This study analyses hygiene, nutrition and health practices in Spanish families with children between 6 and 14 years of age according to the type of family (nuclear, single-parent or reconstituted) and the quantity, age and gender of the children. A representative Spanish national sample of 1103 Spanish parents, 270 fathers and 833 mothers, with children aged 6 to 14, is analysed. The study is descriptive, using statistical techniques with classic indicators (means, percentages). The results show that nuclear families manifest healthier habits, in general, and consider the consumption of pastries, ultra-processed food and excessive amounts of salt to be harmful. Furthermore, this family typology develops healthy and hygienic habits, such as brushing teeth daily, sleeping at least 8 h a day, drinking a glass of milk a day, eating fish more than once a week and eating fast food sporadically. They are also concerned about their children’s annual medical check-ups (paediatrician and dentist). It is concluded that the family type is related to the hygiene and feeding habits of the children.

Where identities converge: The importance of intersectionality in eating disorders research

Disparities in eating disorder (ED) risk, diagnosis, and treatment for those who occupy multiple marginalized social identities (e.g., combined racial/ethnic and sexual minority statuses), underscore the need for advancing multicultural research in the ED field. In this article, we argue that intersectionality-informed approaches, which examine the ways in which one's multiple social identities interact to inform risk for ED outcomes, offer an established framework for identifying frequently underserved individuals who may be at greatest risk for EDs. We highlight preliminary intersectional research in EDs and offer suggestions for further progression. In particular, we encourage future intersectionality-informed research to incorporate a broader range of social identities (e.g., age, ability status), consider the ways in which these identities may be dimensional and fluid, and embrace strengths-based approaches to illuminate dimensions of identity that may serve as protective factors. To support such research, we describe quantitative and qualitative methods for pursuing questions of intersectionality in ED investigations. Given the success of intersectionality-informed research in other areas of psychopathology and its relevance to ED as suggested by initial research, the continued pursuit of these approaches in EDs has high potential to improve identification and treatment for patients who have too often been overlooked.

Eating disorders in adolescent boys and young men: an update

PURPOSE OF REVIEW

To review the recent literature on eating disorders and disordered eating behaviors among adolescent boys and young men, including epidemiology, assessment, medical complications, treatment outcomes, and special populations.

RECENT FINDINGS

Body image concerns in men may involve muscularity, and muscle-enhancing goals and behaviors are common among adolescent boys and young men. Recent measures, such as the Muscularity Oriented Eating Test (MOET) have been developed and validated to assess for muscularity-oriented disordered eating. Medical complications of eating disorders can affect all organ systems in male populations. Eating disorders treatment guidance may lack specificity to boys and men, leading to worse treatment outcomes in these population. Male populations that may have elevated risk of eating disorders and disordered eating behaviors include athletes and racial/ethnic, sexual, and gender minorities.

SUMMARY

Eating disorders and disordered eating behaviors in boys and men may present differently than in girls and women, particularly with muscularity-oriented disordered eating. Treatment of eating disorders in boys and men may be adapted to address their unique concerns.

Household food insecurity: associations with disordered eating behaviours and overweight in a population-based sample of adolescents

OBJECTIVE

To examine how household food insecurity is related to adolescent weight status and disordered eating.

DESIGN

Cross-sectional, population-based study. Adolescents self-reported unhealthy weight control behaviours, binge eating and meal frequency; weight status was measured. Household food insecurity was assessed by asking parents to respond to the validated six-item US Household Food Security Survey Module.

SETTING

Adolescents surveyed within Minneapolis/St. Paul public middle and high schools completed surveys at school, and their parents/guardians were surveyed by mail during the 2009-2010 academic year.

PARTICIPANTS

Ethnically/racially diverse, primarily low-income adolescents (mean age: 14·4 years, range: 10-22 years) and their parents/guardians (n 2285 dyads).

RESULTS

More than one-third (38·9 %) of the adolescents experienced past-year household food insecurity, 43·2 % reported disordered eating and 39·6 % were overweight. Generalised regression models showed that food insecure (FI) compared with food secure (FS) adolescents had higher prevalence of overweight (FI: 42·3 % v. FS: 37·9 %, P = 0·039), lower breakfast consumption (FI: 4·1 times/week v. FS: 4·4 times/week, P = 0·005) and greater use of unhealthy weight control behaviours (FI: 49·0 % v. FS: 39·5 %, P < 0·001) in unadjusted models. Models adjusted for parental education, ethnicity/race, sex and age found that food insecurity was associated with higher prevalence of unhealthy weight control behaviours (FI: 44·5 % v. FS: 37·8 %, P = 0·007), but not with weight status or other eating behaviours.

CONCLUSIONS

These results suggest that food insecurity may be an independent risk factor for unhealthy weight control behaviours, indicating a need to approach these intersecting issues in a comprehensive manner.

Muscles and the Media: A Natural Experiment Across Cultures in Men's Body Image

An increasing number of studies are evidencing relationships between the drive for muscularity and potentially harmful behavioral strategies, such as unhealthy dieting and steroid use amongst men in WEIRD (Western, Educated, Industrialized, Rich, Democratic) populations. As such Western appearance standards proliferate around the world via the media, men who live in other cultural contexts are also at risk of potentially negative effects from aspiring to the “muscular ideal.” However, few studies have explored these relationships in non-WEIRD populations. We investigated men’s body ideals and body image in two non-WEIRD, non-White populations, Uganda (Africa) and Nicaragua (Central America), and compared them with an ethnically diverse sample of men in the United Kingdom. We also examined whether socio-cultural factors including media and ethnicity, predicted the drive for muscularity and body change behaviors among our participants. Results showed that Ugandan men had the least desire for muscularity relative to men in the United Kingdom. Supporting the Tripartite model we found that media and peer influences significantly predicted the drive for muscularity, particularly among men from White British and Nicaraguan Miskitu ethnic groups. By contrast, Creole / Garifuna and Mestizo men from Nicaragua were more likely to want to increase muscularity relative to Black African men from Uganda. Overall, our findings support previous research in demonstrating that there are cultural differences in the kind of body men desire, and that men from WEIRD and non-WEIRD populations may experience similar pressures to aspire to and attain a muscular body type.

Adolescent stress: A predictor of dieting behaviors in youth with overweight/obesity

OBJECTIVE

To examine associations between psychological stress and dieting behavior along with the heterogeneity of this association by gender and race in a diverse sample of adolescents with overweight/obesity.

METHODS

One hundred and sixty-one adolescents between the ages of 13-19 years of age with overweight/obesity (65% female; 53% non-Hispanic black/47% non-Hispanic white; age: 16.7 ± 1.7 years) were recruited from Southeast MI and included in this analysis. Psychological stress was measured using the Perceived Stress Scale, and dieting behavior was assessed using the dieting subscale from the Eating Attitudes Test (EAT-26) questionnaire. Multivariable linear regression models were conducted to examine the association between psychological stress and dieting behavior by gender and race.

RESULTS

Psychological stress was significantly associated with dieting (β = 0.18 ± 0.06; p < 0.01), with greater stress associated with greater frequency of dieting behavior. This relationship remained significant (β = 0.15 ± 0.06; p = 0.016), even when controlling for covariates (age, body fat, gender, race, and pubertal development). There were no statistically significant differences in the association of psychological stress and disordered eating indices by gender or race/ethnicity (p's > 0.05).

CONCLUSIONS

Increased psychological stress is associated with increased dieting behavior among adolescents with overweight/obesity. These findings suggest that psychological stress equally affects dieting behavior among adolescents with overweight/obesity, regardless of gender and race. Future studies should seek to identify the unique sources of psychological stress that contribute to increased dieting behavior among adolescents with overweight/obesity.

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.

The effectiveness of app-based mobile interventions on nutrition behaviours and nutrition-related health outcomes: A systematic review and meta-analysis

A systematic review and meta-analysis were conducted to assess the effectiveness of app-based mobile interventions for improving nutrition behaviours and nutrition-related health outcomes, including obesity indices (eg, body mass index [BMI]) and clinical parameters (eg, blood lipids). Seven databases were searched for studies published between 2006 and 2017. Forty-one of 10 132 identified records were included, comprising 6348 participants and 373 outcomes with sample sizes ranging from 10 to 833, including 27 randomized controlled trials (RCTs). A beneficial effect of app-based mobile interventions was identified for improving nutrition behaviours (g = 0.19; CI, 0.06-0.32, P = .004) and nutrition-related health outcomes (g = 0.23; CI, 0.11-0.36, P < .001), including positive effects on obesity indices (g = 0.30; CI, 0.15-0.45, P < .001), blood pressure (g = 0.21; CI, 0.01-0.42, P = .043), and blood lipids (g = 0.15; CI, 0.03-0.28, P = .018). Most interventions were composed of four behaviour change technique (BCT) clusters, namely, "goals/planning," "feedback/monitoring," "shaping knowledge," and "social support." Moderating effects including study design, type of app (commercial/research app), sample characteristics (clinical/non-clinical sample), and intervention characteristics were not statistically significant. The inclusion of additional treatment components besides the app or the number or type of BCTs implemented did not moderate the observed effectiveness, which underscores the potential of app-based mobile interventions for implementing effective and feasible interventions operating at scale for fighting the obesity epidemic in a broad spectrum of the population.

Cultural considerations for treating Hispanic patients with eating disorders: A case study illustrating the effectiveness of CBT in reducing bulimia nervosa symptoms in a Latina patient

Eating disorders (ED's) are the deadliest of all mental disorders, yet there is a paucity of research examining the clinical presentation of eating disorders in Hispanic populations and limited guidelines for culturally sensitive treatment. Given the rapid growth of Hispanic communities in the U.S., it is important to acknowledge the unique clinical profile of patients within this demographic and examine eating pathology within this socio-cultural context. This case study aims to illustrate the utility, relevance, and effectiveness of cognitive behavioral therapy (CBT) on alleviating eating disorder symptoms in an adult Latina patient with bulimia nervosa to understand the broader implications of applying manualized treatments to diverse populations. We outline the strengths of CBT in quickly modifying problematic thought patterns and decreasing pathological behaviors while raising questions about cultural generalizability. In addition, we explore CBT's limitations in addressing certain underlying ED pathology-driving and maintaining factors for minority individuals.

An Intergenerational Approach to Break the Cycle of Malnutrition

PURPOSE OF REVIEW

This article examines how nutritional status is treated throughout the lifecycle. In doing so, the review identifies promising life stages during which intervention may improve nutritional status of future generations.

RECENT FINDINGS

A life course perspective suggests that nutritional changes are most likely to be sustained when they occur during times of developmental transition, such as pregnancy or adolescence. Adolescence is a unique period in which malnutrition in future generations may be addressed because it is the first life stage at which pregnancy becomes feasible and individuals seek independence from parents. A need exists to begin investigating not just how nutrition changes are sustained throughout the lifespan, but how nutritional intervention in one generation impacts the next. This intergenerational approach should be undertaken with cross-discipline collaboration to have the best chance at impacting underlying determinants of malnutrition like poverty and women's education.

Risk of disordered eating at the intersection of gender and racial/ethnic identity among U.S. high school students

BACKGROUND

Gender and racial/ethnic disparities in disordered eating among youth exist, although whether having multiple marginalized identities disproportionately increases risk is unclear. Therefore, we aimed to quantify the risk of disordered eating associated with intersecting gender and racial/ethnic identities of U.S. adolescents.

METHODS

We analyzed data from 11,514 U.S. high school students identifying as White, Black/African American, or Hispanic/Latino who participated in the 2013 National Youth Risk Behavior Surveillance System. Age-adjusted relative risks (RR) of purging, fasting, diet pill use, and any disordered eating were estimated using log-binomial models. Relative excess risk due to interaction (RERI) was estimated to evaluate the degree to which the combined effect of marginalized gender and racial/ethnic identity was larger than the sum of their individual effects.

RESULTS

Disordered eating was prevalent (girls: 20.4% Black/African American, 29.2% Hispanic/Latina, 21.4% White; boys: 13.4% Black/African American, 12.4% Hispanic/Latino; 8.1% Whites). Girls of all racial/ethnic identities and racial/ethnic minority boys had elevated risks of purging, fasting, and any disordered eating compared to White boys (RR range = 1.57-7.43); Hispanic/Latina and White girls also had elevated risk of diet pill use (RR range = 1.98-3.20). Among Hispanic/Latina girls, positive interaction between gender and race/ethnicity produced excess risk of any disordered eating and purging (RERI: any = 0.42 (95% confidence interval (CI) = -0.02, 0.87); purging = 1.74 (95% CI = 0.06, 3.42).

CONCLUSIONS

Findings illustrate the advantages of adopting an intersectional approach to disordered eating research. Future research should investigate the mechanisms of these disparities.

Associations between Race and Eating Disorder Symptom Trajectories in Black and White Girls

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.
