A prospective study on the link between weight-related self-stigma and binge eating: Role of food addiction and psychological distress

The relationship between internalised weight bias and biopsychosocial outcomes in children and youth: a systematic review

OBJECTIVE

To synthesise the evidence on the relationships between internalised weight bias (IWB) and biopsychosocial health outcomes in individuals ≤ 25 years.

METHODS

A systematic review was conducted by searching five scientific databases up to May 2022 to retrieve studies that investigated associations between IWB and biopsychosocial outcomes. Articles with participants ≤ 25 years, at least one validated measure of IWB, one measure of a biopsychosocial outcome, and were observational were included. Excluded articles involved systematic literature reviews, case study reports, intervention studies, meta-analyses, grey literature, pilot, and feasibility studies. Quality assessment was carried out using the American Dietetic Association Quality Criteria Checklist. The protocol was registered with PROSPERO, ID number CRD42022323876.

RESULTS

Two hundred and sixty-six articles were identified. Nineteen were eligible for inclusion, (15 cross-sectional and 4 prospective). The Weight Bias Internalization Scale and the Weight Self-Stigma Questionnaire were the most used tools to assess IWB with large heterogeneity in tool types used to assess biopsychosocial measures. IWB had positive associations with psychopathology, eating disorder symptomology, higher BMI, being female, and experiences of weight stigma. It was negatively associated with quality of life, body image, physical activity, social ability, self-esteem, and socioeconomic status.

DISCUSSION

IWB associated with adverse biopsychosocial outcomes in children and youth populations. IWB may be more clinically relevant in assessing at-risk children and youth than physical weight due to its psychosocial aspects and ability to expand beyond the scope of BMI. Research would benefit from better assessment tools designed for children and youth that accurately measure IWB. Future research should focus on increased diversity and longitudinal study designs with children and youth-specific populations.

A systematic review of weight stigma and disordered eating cognitions and behaviors

Weight stigma is persistent across contexts and is associated with disordered eating cognitions and behaviors. This systematic review aimed to examine the existing literature that has explored the relationship between weight stigma and disordered eating cognitions and behaviors. We specifically examined three dimensions of weight stigma - experienced, anticipated, and internalized - and adopted an inclusive conceptualization of outcomes related to disordered eating (including constructs such as binge eating, body dissatisfaction, and other cognitions and behaviors such as dietary restraint, unhealthy weight control behaviors, and drive for thinness). We searched PubMed, Embase, CINAHL, Web of Science, Sociological Abstracts, and PsycINFO for English-language, peer-reviewed articles and dissertations with quantitative methodology published through October 2023. The search resulted in 242 articles meeting inclusion criteria. A narrative review found a consistent relationship between greater weight stigma and more disordered eating cognitions and behaviors. Methodological and theoretical limitations are discussed, as are critical avenues for future research and potential clinical implications stemming from this body of research. Given the widespread nature and impact of weight stigma on disordered eating, it is imperative that we intervene to address weight stigma at all levels, from the structural to the intrapersonal.

Weight stigma in healthcare settings: the experience of Arab and Jewish bariatric surgery candidates in Israel

BACKGROUND

Weight-related stigma and discrimination are prevalent in our society with adverse biopsychosocial outcomes to people with obesity and morbid obesity. Studies suggest that weight bias in healthcare settings are quite prevalent, but there have been, as far as we know, lack of studies examining prevalence and correlates of weight bias experiences among bariatric surgery candidates in Israel. We aim to understand the nature and prevalence of weight stigma among bariatric surgery candidates. To identify differences between Jewish and Arab candidates. To examine the impact of weight stigma experiences on weight bias internalization (WBI).

METHODS

A cross-sectional study was performed among 117 adult bariatric surgery candidates from three hospitals in northern Israel (47.8% Jews, 82.4% females, average BMI 42.4 ± 5.2 Kg/meter2). Patients who agreed to participate completed a structured questionnaire on the same day that the bariatric surgery committee met. WBI was measured using a validated 10-item scale. Experiences of weight stigma were measured using items adapted from prior international studies.

RESULTS

About two thirds of the participants had at least one experience of weight stigma (teased, treated unfairly, or discriminated against because of their weight). As many as 75% of participants reported that weight served as a barrier to getting appropriate health care and as many as half of participants felt in the last year that a doctor judged them because of their weight. No significant differences were found between Arabs and Jews in the prevalence of weight stigma experiences and WBI. However, a trend towards more stigma experiences among Jews was noted. WBI was predicted by female gender and experiences of weight stigma, both in general and within healthcare settings.

CONCLUSIONS

Weight stigma towards bariatric surgery candidates in Israel is quite prevalent, and specifically in healthcare settings. It is important to adopt policy actions and intervention programs to improve awareness to this phenomenon among the general public and specifically among healthcare providers, as many healthcare providers may be unaware of the adverse effect of weight stigma and of ways in which they are contributing to the problem. Future studies may validate our findings using larger sample size and longitudinal design.

Mediating Roles of Psychological Distress, Insomnia, and Body Image Concerns in the Association Between Exercise Addiction and Eating Disorders

Purpose

Exercising can promote good health. However, excessive exercising may have downsides. This study examined the association between exercise addiction and eating disorders and whether the identified association was mediated by psychological distress, insomnia (including sleep quality), and body image concern.

Methods

A total of 2088 adolescents (mean age of 15.3 years) participated in this cross-sectional study by questions assessing exercise addiction, eating disorders, psychological distress, insomnia, sleep quality, and body image concern.

Results

There were significantly positive relationships between the variables (r=0.12-0.54, p<0.01) with effect sizes from small to large. The four potential mediators (ie, insomnia, sleep quality, psychological distress, and body image concern), individually and in total, significantly mediated the association between exercise addiction and eating disorders.

Conclusion

The findings suggest that exercise addiction in adolescents may influence eating disorders through multiple pathways, such as insomnia, psychological distress, and body image concerns. Future research should examine these relationships longitudinally and use gathered information to inform intervention development. Clinicians and healthcare workers are encouraged to assess exercise addiction when treating individuals with eating disorders.

Eating disorder risk in rural US adolescents: What do we know and where do we go?

Adolescence is a vulnerable period for the development of eating disorders, but there are disparities in eating disorder risk among adolescents. One population that may be at increased risk but is vastly understudied, is adolescents residing in rural regions within the United States. Rural communities face many mental and physical health disparities; however, the literature on rural adolescent eating disorder risk is nearly nonexistent. In this paper we summarize the scant literature on disordered eating and eating disorder risk and prevalence among rural US adolescents. We also detail eating disorder risk factors that may have unique influence in this population, including socioeconomic status, food insecurity, healthcare access, body image, and weight stigma. Given the presence of numerous eating disorder risk factors, we speculate that rural adolescents may be a particularly vulnerable population for eating disorders and we propose critical next steps in research for understanding eating disorder risk among the understudied population of rural adolescents. PUBLIC SIGNIFICANCE: Rural adolescents may be at increased risk for eating disorders due to disproportionate burden of known risk factors, though this relationship remains understudied. We present a summary of the literature on prevalence and unique risk factors, proposing that this may be a high-risk population. We detail next steps for research to understand eating disorder risk in this population to inform future prevention, identification, and treatment efforts needed in this community.

Exploring mediational roles for self-stigma in associations between types of problematic use of internet and psychological distress in youth with ADHD

BACKGROUND

Several studies have linked the problematic use of the Internet (PUI) to psychological distress. Youth with attention deficit hyperactivity disorder (ADHD) are considered a particular disadvantaged population with a high risk of developing PUI, psychological distress, and self-stigma. Nonetheless, the interrelationships of PUI, self-stigma, and psychological distress in adolescents with ADHD are not well understood.

AIMS

This study investigated whether self-stigma mediates relationships between different forms of PUI, such as problematic gaming (PG), problematic social media use (PSMU), problematic smartphone use (PSPU), and psychological distress (i.e., depression, anxiety, and stress), in children with ADHD.

METHODS AND PROCEDURES

We recruited 100 youth with ADHD (mean age=10.80 [SD=3.07] years; 84 boys) from psychiatric outpatient clinics in Taiwan. All participants were assessed for PUI (via Internet Gaming Disorder-Short Form for PG, Bergan Social Medica Addiction Scale for PSMU, and Smartphone Application-Based Addiction Scale for PSPU), self-stigma (via Self-Stigma Short-Scale), and psychological distress (via Depression, Anxiety, Stress Scale).

OUTCOMES AND RESULTS

The results of path and bootstrapping analyses indicated that self-stigma mediated the associations between PSMU and PSPU, but not PG, and depression, anxiety, and stress.

CONCLUSIONS AND IMPLICATIONS

This study expands the extant literature by revealing that self-stigma mediates the association between specific forms of PUI and psychological distress in adolescents with ADHD. Interventions aimed at reducing self-stigma and PUI, particularly PSMU and PSPU, may help decrease psychological distress among adolescents with ADHD.

Sequentially mediated effects of weight-related self-stigma and psychological distress in the association between perceived weight stigma and food addiction among Taiwanese university students: A cross-sectional study

BACKGROUND

Weight-related stigma has negative physiological and psychological impacts on individuals' quality of life. Stigmatized individuals may experience higher psychological distress and therefore increase the potential risk to develop obesity and/or food addiction. The present study examined the associations and mediated effect between perceived weight stigma, weight-related self-stigma, and psychological distress in explaining food addiction among Taiwanese university students.

METHODS

All participants (n = 968) completed an online survey which included the Perceived Weight Stigma Questionnaire, Weight Self-Stigma Questionnaire, Depression, Anxiety, Stress Scale-21, and Yale Food Addiction Scale Version 2.

RESULTS

After controlling for demographic variables, significant associations were found in the paths from (1) perceived weight stigma to weight-related self-stigma ([Formula: see text] = 0.23), psychological distress ([Formula: see text] = 0.35), and food addiction ([Formula: see text] = 0.23); (2) weight-related self-stigma to psychological distress ([Formula: see text] = 0.52) and food addiction ([Formula: see text] = 0.59); and (3) psychological distress to food addiction ([Formula: see text] = 0.59) (all p-values < 0.001). The mediation model showed the sequential mediated effect of weight-related self-stigma and psychological distress in the association between perceived weight stigma and food addiction.

CONCLUSIONS

The results provide novel insights that weight-related self-stigma and psychological distress sequentially mediated the relationship between perceived weight stigma and food addiction among Taiwanese university students. The findings of the present study could be implemented into interventions that aim to reduce food addiction derived from weight-related stigma. Future studies should consider group analysis to consider confounding factors or other populations to provide more evidence regarding the mechanism of weight-related stigma.

Estimation of Behavioral Addiction Prevalence During COVID-19 Pandemic: A Systematic Review and Meta-analysis

Purpose of Review

The COVID-19 pandemic changed people’s lifestyles and such changed lifestyles included the potential of increasing addictive behaviors. The present systematic review and meta-analysis aimed to estimate the prevalence of different behavioral addictions (i.e., internet addiction, smartphone addiction, gaming addiction, social media addiction, food addiction, exercise addiction, gambling addiction, and shopping addiction) both overall and separately.

Recent Findings

Four databases (PubMed, Scopus, ISI Web of Knowledge, and ProQuest) were searched. Peer-reviewed papers published in English between December 2019 and July 2022 were reviewed and analyzed. Search terms were selected using PECO-S criteria: population (no limitation in participants’ characteristics), exposure (COVID-19 pandemic), comparison (healthy populations), outcome (frequency or prevalence of behavioral addiction), and study design (observational study). A total of 94 studies with 237,657 participants from 40 different countries (mean age 25.02 years; 57.41% females). The overall prevalence of behavioral addiction irrespective of addiction type (after correcting for publication bias) was 11.1% (95% CI: 5.4 to 16.8%). The prevalence rates for each separate behavioral addiction (after correcting for publication bias) were 10.6% for internet addiction, 30.7% for smartphone addiction, 5.3% for gaming addiction, 15.1% for social media addiction, 21% for food addiction, 9.4% for sex addiction, 7% for exercise addiction, 7.2% for gambling addiction, and 7.2% for shopping addiction. In the lockdown periods, prevalence of food addiction, gaming addiction, and social media addiction was higher compared to non-lockdown periods. Smartphone and social media addiction was associated with methodological quality of studies (i.e., the higher the risk of boas, the higher the prevalence rate). Other associated factors of social media addiction were the percentage of female participants, mean age of participants, percentage of individuals using the internet in country, and developing status of country. The percentage of individuals in the population using the internet was associated with all the prevalence of behavioral addiction overall and the prevalence of sex addiction and gambling addiction. Gaming addiction prevalence was associated with data collection method (online vs. other methods) that is gaming addiction prevalence was much lower using online methods to collect the data.

Summary

Behavioral addictions appeared to be potential health issues during the COVID-19 pandemic. Healthcare providers and government authorities should foster some campaigns that assist people in coping with stress during COVID-19 pandemics to prevent them from developing behavioral addictions during COVID-19 and subsequent pandemics.

Body Weight, Weight Self-Perception, Weight Teasing and Their Association with Health Behaviors among Chinese Adolescents-The Shanghai Youth Health Behavior Survey

Weight-related status has been associated with the physical and psychological health of adolescents. This cross-sectional study evaluated three different kinds of weight-related statuses (Body Mass Index (BMI), weight self-perception and weight teasing from others) among Chinese adolescents and identified their associations with health risk behaviors (lack of healthy dietary behavior, unhealthy dietary behavior, binge eating behavior, lack of physical activity (PA), sedentary behaviors (SB) and sleep disturbance). A stratified random cluster sampling method was used to select 10,070 students aged 11−18 years old from schools in Shanghai. Self-reported questionnaires were collected, weight-related statuses were divided into three categories and six specific health risk behaviors were classified into two groups: positive or negative. Overall, 27.82% of the adolescents were classified as being overweight and obese (35.61% of boys and 18.21% of girls), 43.45% perceived themselves as too heavy and 30.46% experienced weight teasing in the past. Among overweight or obese participants, 50.55% have been teased about their weight, and 77.48% perceived themselves as too heavy. Weight perception and weight teasing were significantly associated with health risk behaviors rather than the actual body weight status based on BMI, especially regarding binge eating behavior (body weight status (BMI): p > 0.05, underweight perception: OR = 1.18, 95%CI 1.03−1.34; weight teasing for more than once a year: OR = 2.00, 95%CI 1.76−2.27). In addition, weight perception and weight teasing were significantly associated with health risk behaviors, mainly in normal and overweight/obese groups but not in underweight groups. Weight teasing and weight self-perception play an independent and stronger role than actual body weight in the health behaviors of adolescents. This calls for more attention and intervention to reduce peer bullying and stigmas on weight among adolescents.

Binge Eating Disorder Is a Social Justice Issue: A Cross-Sectional Mixed-Methods Study of Binge Eating Disorder Experts' Opinions

BACKGROUND

Binge eating disorder is an autonomous DSM-V diagnosis characterized by discrete rapid consumption of objectively large amounts of food without compensation, associated with loss of control and distress. Environmental factors that contribute to binge eating disorder continue to evolve. This mixed-methods cross-sectional study assessed whether there is consensus among experts in the field about environmental factors that influence adult binge eating disorder pathology.

METHODS

Fourteen expert binge eating disorder researchers, clinicians, and healthcare administrators were identified internationally based on federal funding, PubMed-indexed publications, active practice in the field, leadership in relevant societies, and/or clinical and popular press distinction. Semi-structured interviews were recorded anonymously and analyzed by ≥2 investigators using reflexive thematic analysis and quantification.

RESULTS

Identified themes included: (1) systemic issues and systems of oppression (100%); (2) marginalized and under-represented populations (100%); (3) economic precarity and food/nutrition insecurity/scarcity (93%); (4) stigmatization and its psychological impacts (93%); (5) trauma and adversity (79%); (6) interpersonal factors (64%); (7) social messaging and social media (50%); (8) predatory food industry practices (29%); and (9) research/clinical gaps and directives (100%).

CONCLUSIONS

Overall, experts call for policy changes around systemic factors that abet binge eating and for greater public education about who can have binge eating disorder. There is also a call to take and account for the narratives and life experiences of individuals with binge eating disorder to better inform our current understanding of the diagnosis and the environmental factors that impact it.

Clinical Considerations of Ultra-processed Food Addiction Across Weight Classes: an Eating Disorder Treatment and Care Perspective

Purpose of Review

To examine the prevalence rates of ultra-processed food addiction across different weight classes and offer guidelines for diagnosis and treatment. Clinicians are provided with practical considerations in the assessment of ultra-processed food addiction beyond the use of validated instruments.

Recent Findings

The weighted mean prevalence of ultra-processed food addiction is approximately 20% worldwide and varies widely based on the sample. At first glance, there appears a linear relationship between ultra-processed food addiction and BMI class. Further investigation indicates a J-shaped curve with heightened prevalence among the underweight. These findings highlight the need to assess for additional factors that may increase objective or subjective food addiction symptoms including eating disorders, dietary restraint, and other mental health diagnoses.

Summary

While clinical considerations across different weight classes vary, overemphasis on weight status may detract from the clinical utility of the ultra-processed food addiction construct. Considering weight status in conjunction with other psychiatric symptoms helps to better understand the various biopsychosocial mechanisms that influence eating behavior and can inform individualized treatment strategies.

Risk of eating disorders in a representative sample of Italian adolescents: prevalence and association with self-reported interpersonal factors

PURPOSE

Adolescence represents a critical period for the onset of eating disorders (EDs). The present study aimed to provide the prevalence of individuals at risk for EDs psychopathology in a representative population of adolescents aged 14-19 and to characterize this population regarding interpersonal and psychological factors.

METHODS

The percentage of participants at risk for EDs in a representative high school population was assessed through the SCOFF screening questionnaire (cut-off score: 3) in the total sample (N: 6551) and in gender-based subgroups for different body mass index (BMI) categories. Odds ratios for being at risk of ED (SCOFF ≥ 3) were esteemed in a multivariable analysis including self-reported parental education, quality of family and peer relationships, bullying victimization, age at first sexual intercourse, and psychological distress.

RESULTS

A SCOFF score ≥ 3 was found in 31.0% of participants (boys: 19.4%; girls: 44.6%), with a greater prevalence among higher BMI categories. Bad family relationships, being bullied, having the first sexual intercourse before the age of 14, and experiencing high distress were associated with this risk condition. Among girls, bad peer relationships were associated with a low-risk SCOFF score.

CONCLUSION

A remarkable percentage of adolescents reported significant body image or eating concerns. Screening programs are deeply needed, and particular attention should be devoted to interpersonal factors, such as the quality of family relationships and interactions with peers, which represent potential indicators of this vulnerability.

Anxiety and Food Addiction in Men and Women: Results From the Longitudinal LIFE-Adult-Study

BACKGROUND

Anxiety is a widespread phenomenon, and it is connected to disordered eating and obesity. We want to analyze the connection between anxiety and food addiction (FA) over two points in time to better understand the directionality of the association. Since there are gender differences with regard to anxiety and eating, we are also interested in differences between men and women.

METHODS

We used data from the population-based LIFE-Adult-Study (N = 1,474) at time 1 (baseline) and time 2 (first follow-up) to analyze the connections between anxiety (GAD-7) and FA (YFAS) using a multiple group latent cross-lagged panel model with female and male participants as groups. We controlled for age, marital status, socioeconomic status and social support.

RESULTS

Anxiety (women: β = 0.50, p ≤ 0.001; men: β = 0.59, p ≤ 0.001) as well as FA (women: β = 0.37, p ≤ 0.001; men: β = 0.58, p ≤ 0.001) exhibited stability over time for both genders. We found a significant association between anxiety at time 1 and FA at time 2 for women (β = 0.25, p ≤ 0.001) but not for men (β = 0.04, p = 0.10), and significant associations between FA at time 1 and anxiety at time 2 for women (β = 0.23, p ≤ 0.001) as well as men (β = 0.21, p ≤ 0.001).

CONCLUSION

Food addiction longitudinally affects anxiety, independent of gender and other sociodemographic variables. In addition, anxiety affects subsequent FA as well, but only in women. Interventions that address FA could reduce anxiety in men and women, while interventions that mitigate anxiety could help prevent FA in women.

Adverse Childhood Experiences and Weight Stigma: Co-Occurrence and Associations with Psychological Well-Being

Prior research has demonstrated that individuals with a higher body weight (i.e., obesity) have a relatively high incidence of adverse childhood experiences (ACEs) (e.g., abuse, neglect). Individuals with obesity are also susceptible to experiencing and internalizing weight stigma. Negative physical and mental health consequences have been associated with both ACEs and weight stigma, yet the interplay between these factors has not been explored. The current study examined ACEs in a sample of 105 treatment-seeking adults with obesity who all reported having experienced and internalized weight stigma (90.5% women, 70.5% non-Hispanic White, mean age=49.1 years). The study aimed to 1) provide a descriptive overview of rates of ACEs in this unique sample of adults with potentially high psychological vulnerability and 2) assess associations between ACEs, weight stigma, and psychological well-being. Over three-fourths of participants (76.2%) reported experiencing at least one ACE. The total number of ACEs was significantly associated with more frequent experiences of and greater distress about weight stigma during childhood, as well as higher current perceived stress. Experiencing weight stigma for the first time in childhood was also associated with more reported ACEs. ACEs of abuse were associated with more lifetime reported experiences of weight stigma and greater internalization, use of eating as a strategy to cope with weight stigma, and higher perceived stress. These findings have implications for early identification of and tailored interventions for individuals who have experienced adverse events and weight stigma at a young age.

Contextualising Eating Disorder Concerns for Paediatric Obesity Treatment

PURPOSE OF REVIEW

Eating disorders are complex mental health conditions that share risk factors with obesity. This review outlines the context for concerns that paediatric obesity treatment presents a risk for eating disorder development.

RECENT FINDINGS

Most children and adolescents undergoing professionally supervised obesity treatment will have improvements or no change to eating disorder risk profiles. However, some may subsequently develop a clinical eating disorder, and this is proposed to relate to weight-focussed dietary interventions that are standard in paediatric obesity treatment. Nevertheless, dietary restraint may not be a strong predictor of eating disorder risk in the context of paediatric obesity treatment. Most international guidelines recommend weight maintenance or weight loss as a treatment goal, and weight loss is related to improvements in cardiometabolic health but not eating disorder risk in the short term. The risk of inducing or exacerbating an eating disorder during paediatric weight management is likely to be low; however, the serious consequences combined with increasing scale of obesity treatment, and lack of empirical evidence, are of concern. There is a need for further research to identify long-term predictors of eating disorder development for children and adolescents who seek treatment for their obesity.

Interactive influences of food, contexts and neurocognitive systems on addictive eating

Compulsive eating is a common symptom of different conditions, including obesity, binge eating disorder and bulimia. One hypothesis is that contemporary food products promote compulsive eating via addiction-like mechanisms. However, what is the addictive substance in food, and what is the phenotypic overlap between obesity / eating disorders and addictions are questions that remain unresolved. In this review, we applied a multilevel framework of addiction, which encompasses the 'drug' (certain foods), the person's mindset, and the context, to improve understanding of compulsive eating. Specifically, we reviewed evidence on the addictive properties of specific foods, the neurocognitive systems that control dietary choices, and their interaction with physical, emotional and social contexts. We focused on different target groups to illustrate distinct aspects of the proposed framework: the impact of food and contextual factors were examined across a continuum, with most studies conducted on healthy participants and subclinical populations, whereas the review of neurocognitive aspects focused on clinical groups in which the alterations linked to addictive and compulsive eating are particularly visible. The reviewed evidence suggest that macronutrient composition and level of processing are associated with the addictive properties of food; there are overlapping neuroadaptations in reward and decision-making circuits across compulsive eating conditions; and there are physical and social contexts that fuel compulsive eating by exploiting reward mechanisms and their interaction with emotions. We conclude that a biopsychosocial model that integrates food, neurobiology and context can provide a better understanding of compulsive eating manifestations in a transdiagnostic framework.

Validation of the modified weight bias internalization scale in a Spanish adult population

Weight bias internalization has received considerable attention in recent years and has been associated with serious psychological and physical consequences in Westernized societies. The modified weight bias internalization scale (WBIS-M) is one of the most frequently used instruments for assessing internalized weight stigma across different body weight categories. The aim of this study was to adapt the WBIS-M for use in Spanish adult populations. The sample consisted of 678 participants from the Spanish general population recruited through the internet, 79.6% of whom were women. The scale was translated into Spanish and then backtranslated. To study the internal structure, a cross-validation analysis was carried out including both exploratory and confirmatory factor analyses to assess the scale's psychometric properties. Internal consistency was evaluated using Cronbach's alpha and McDonald's omega and a test-retest was conducted to assess one-month stability. Results confirmed that the Spanish adaptation of the WBIS-M is an 11-item unidimensional scale, like the original version and shows excellent psychometric properties. In conclusion, the Spanish WBIS-M version seems to be a robust psychometric tool for use in clinical and research settings.

Food addiction and mental health in adolescents: a systematic review

The intersection between eating behaviours and mental health has garnered substantial attention in recent years. For this Review, we systematically reviewed the available research to find out the prevalence of food addiction as measured by the Yale Food Addiction Scale, and to investigate its association with mental health-related outcomes in adolescents. Eight databases were searched using keywords from Jan 1, 2009, to Aug 5, 2020, to identify studies reporting a Yale Food Addiction Scale diagnosis or symptom score, or both. In total, 27 studies were included. The prevalence of a food addiction diagnosis ranged from 2·6% to 49·9% in non-clinical and clinical populations, and prevalence was higher in women and adolescents with a higher weight status. Food addiction was associated with disordered eating, depressive and anxiety symptoms, and a poorer quality of life and self-esteem. These associations have important implications for the assessment and management of eating behaviours and mental health in adolescents. Transdiagnostic prevention and management intervention strategies could be explored.

Prevalence of food addiction in children and adolescents: A systematic review and meta-analysis

Food addiction (FA) has been as a construct that is associated with childhood obesity. However, relatively little is known regarding the prevalence of FA among children and adolescents. An instrument designed to assess FA among youth, the Yale Food Addiction Scale for Children and Adolescents (YFAS-C), has been developed and used to estimate FA prevalence among pediatric populations. The present systematic review and meta-analysis aimed to synthesize the results of FA prevalence among youth. Using keywords related to FA and children to search PubMed, Embase, Scopus, and Web of Science, we identified and analyzed 22 cross-sectional studies. No longitudinal studies were identified in the search. Meta-analysis with Freeman-Tukey Double Arcsine transformation was conducted to estimate FA prevalence. Meta-regression was applied to understand whether weight status (i.e., data from community samples vs. overweight/obese samples) is associated with FA. Eligible studies (N = 22) were analyzed using 6,996 participants. The estimated FA prevalence was 15% (95% CI 11-19%) for all samples, 12% (95% CI 8-17%) for community samples, and 19% (95% CI 14-26%) for overweight/obese samples. Meta-regression indicated that weight status was associated with FA severity (p = 0.002) and marginally with FA prevalence (p = 0.056). Healthcare providers should consider and address the high FA prevalence among pediatric population.

Eating disorder risk in adolescents with obesity

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

Weight Stigma in Youth: Prevalence, Consequences, and Considerations for Clinical Practice

PURPOSE OF REVIEW

This review summarizes recent evidence on weight stigma experienced by youth with overweight or obesity. We examine the prevalence and sources of weight-based victimization targeting youth, consequences of these stigmatizing experiences for their psychological and physical health, and considerations for addressing weight stigma in clinical practice and pediatric care.

RECENT FINDINGS

Weight stigma is highly prevalent among youth with high body weight, who are targets of weight-based victimization from peers, parents, and teachers. These experiences place youth at risk for psychological distress (primarily depressive symptoms, low self-esteem, and suicidal ideation), worse social and academic outcomes, and adverse physical health consequences including maladaptive eating behaviors, lower physical activity, substance use, and weight gain. Healthcare professionals and clinicians have important roles to play in efforts to help reduce weight stigma and support youth with obesity. Fundamental to these efforts is the use of supportive, compassionate, and non-stigmatizing communication with youth and their families.

Food Addiction and Psychosocial Adversity: Biological Embedding, Contextual Factors, and Public Health Implications

The role of stress, trauma, and adversity particularly early in life has been identified as a contributing factor in both drug and food addictions. While links between traumatic stress and substance use disorders are well documented, the pathways to food addiction and obesity are less established. This review focuses on psychosocial and neurobiological factors that may increase risk for addiction-like behaviors and ultimately increase BMI over the lifespan. Early childhood and adolescent adversity can induce long-lasting alterations in the glucocorticoid and dopamine systems that lead to increased addiction vulnerability later in life. Allostatic load, the hypothalamic-pituitary-adrenal axis, and emerging data on epigenetics in the context of biological embedding are highlighted. A conceptual model for food addiction is proposed, which integrates data on the biological embedding of adversity as well as upstream psychological, social, and environmental factors. Dietary restraint as a feature of disordered eating is discussed as an important contextual factor related to food addiction. Discussion of various public health and policy considerations are based on the concept that improved knowledge of biopsychosocial mechanisms contributing to food addiction may decrease stigma associated with obesity and disordered eating behavior.

The Mediating Effects of Eating Disorder, Food Addiction, and Insomnia in the Association between Psychological Distress and Being Overweight among Iranian Adolescents

With obesity and excess weight remaining a serious concern worldwide, investigating the mechanisms underlying this is of great importance. Psychological distress is a possible trigger contributing to excess weight for adolescents. Moreover, the association between psychological distress and excess weight may be mediated by eating disorder, food addiction, and insomnia. The present study utilized parallel mediation analysis to assess the aforementioned associations and possible mediation effects among Iranian adolescents. Through stratified and clustered sampling, adolescents (N = 861; mean ± SD age = 15.9 ± 3.2; 372 males) participated and were followed for a one-year period. Excess weight (standardized body mass index, z-BMI); psychological distress (Depression, Anxiety, and Stress Scale-21); eating disorder attitudes (Eating Attitude Test-26); food addiction (Yale Food Addiction Scale for Children); and insomnia (Insomnia Severity Index) were assessed. Eating disorder attitudes, food addiction, and insomnia were significant mediators in the association of psychological distress and z-BMI. Additionally, psychological distress had direct effects on z-BMI. Given that eating disorder attitudes, food addiction, and insomnia showed mediated effects in the temporal association of psychological distress and excess weight, healthcare providers are encouraged to design programs on improving these three mediators to help adolescents overcome excess weight problems.

Psychological Quality of Life in People with Physical Disability: The Effect of Internalized Stigma, Collective Action and Resilience

PURPOSE

The main objective of this study was to examine the role of social identification, collective action and resilience in reducing the negative consequences of internalized stigma on the psychological quality of life of people with physical disability using path analysis. We propose a model with two paths: the first through social identification and collective action and the second via resilience.

METHOD

A total of 288 Spanish people with physical disability aged between 18 and 82 years (46.4% males; mean [SD] of age = 45.1 [12.3] responded to the questionnaire. Data were collected for three months through an online survey.

RESULTS

The tested model adequately fit the data. We found that the relationship between internalized stigma and the psychological quality of life of people with physical disability was mediated by resilience. However, neither social identification nor collective action mediated the association between internalized stigma and quality of life among our participants.

CONCLUSIONS

The results confirmed the negative association between internalized stigma and quality of life in the population with physical disability. The results show that some interactive processes, such as resilience, may contribute to decreasing the negative effects of internalized stigma. In contrast, no effects of identification with the group or collective action intention were found.
