Global Proportion of Disordered Eating in Children and Adolescents: A Systematic Review and Meta-analysis

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.

Mental health after the COVID-19 pandemic among Finnish youth: a repeated, cross-sectional, population-based study

BACKGROUND

High levels of mental health problems among young people were reported during the COVID-19 pandemic, but studies of the post-pandemic period are scarce. We assessed mental health problems among Finnish youth before, during, and after the COVID-19 pandemic using nationwide population-based samples. Our aim was to examine in which direction the heightened levels of adolescent mental health problems have developed after the pandemic.

METHODS

In this national, repeated cross-sectional, population-based study in Finland, we recruited students at lower and upper secondary level (aged 13-20 years) who were taking part in the Finnish School Health Promotion (SHP) survey in 2015-23 (119 681-158 897 participants per round). The SHP is based on total sampling and conducted biennially between March and May. Self-reports covered the seven-item Generalized Anxiety Disorder Scale; the two-item Patient Health Questionnaire for depression; the Mini Social Phobia Inventory for social anxiety; the Short Warwick-Edinburgh Mental Wellbeing Scale for mental wellbeing; loneliness; the Sick, Control, One Stone, Fat, Food measure for disordered eating; and suicidality (suicidal ideation, deliberate self-harm, and suicide attempts). Scales were dichotomised using validated cutoffs. Presence of any and comorbid mental health problems was assessed. Logistic (for dichotomised outcomes) and linear (for Short Warwick-Edinburgh Mental Wellbeing Scale) mixed effects models were used to analyse the effect of survey year on mental health, controlling for sociodemographic background factors and stratified by gender and school level. Cisgender and transgender youth were compared.

FINDINGS

Between 2015 and 2023, the SHP study recruited 722 488 students (371 634 [51·6%] girls and 348 857 [48·4%] boys) with a mean age of 15·8 years (SD 1·3) who were either in the eighth and ninth grades of comprehensive school or the first and second years of general and vocational upper secondary schools in Finland. The proportion of participants with generalised anxiety, depression, and social anxiety symptoms above the cutoff increased from pre-COVID-19 levels to 2021 and remained at these higher levels in 2023 among all study groups. Among girls in lower secondary education, prevalence of generalised anxiety, depression, and social anxiety symptoms increased from 2021 to 2023, as did social anxiety among girls in upper secondary education. Among boys, the proportion with social anxiety symptoms decreased between 2021 and 2023. Mental wellbeing scores decreased in all groups between 2021 and 2023, and disordered eating increased in girls, and in boys in lower secondary education. Suicidality increased in girls but not in boys. Loneliness was the only measure to show improvement in all groups from 2021 to 2023. In 2023, 55 895 (72·6%) of 76 994 girls and 22 718 (32·8%) of 69 205 boys reported at least one mental health problem, and 37 250 (48·4%) girls and 9442 (13·6%) boys reported comorbid mental health problems. Among both transfeminine and transmasculine youth, the prevalence of generalised anxiety and depression symptoms decreased from 2021 to 2023, but compared with cisgender youth, the proportions were significantly higher throughout.

INTERPRETATION

The effects of the COVID-19 pandemic on youth mental health could be long lasting. In this study, the substantial change for the better among transgender youth was a positive exception. Providing adequate support and treatment for young people with poor mental health is essential, but solutions to the mental health crisis need to address a wider societal perspective and should be developed in partnership with young people.

Black and Latiné parents' perspectives on supporting their children's emotional and physical health

Informed by integrative models of cultural resilience, the purpose of this study was to (a) explore how parents are promoting their children's emotional and physical health, with a focus on race and ethnic-racial socialization strategies, and (b) identify the barriers and challenges parents are experiencing in supporting their children's health. Ethnically racially matched qualitative interviews were conducted with 33 parents (82% women, 64% Black, 36% Latiné). Results of thematic analysis revealed three overarching themes: (a) Strategies for Promoting Children's Physical and Emotional Health, (b) Challenges Promoting Children's Physical and Emotional Health, and (c) Impact of Racism on Parenting and Children's Health. Most parents believed that racism had an impact on their parenting decisions and their children's health; however, there were some differences in ethnic-racial socialization practices between Black and Latiné parents. Findings have implications for culturally relevant parenting approaches to support children's emotional and physical health.

Factor structure, group invariance, and concurrent validity of scores from the college eating and drinking behavior scale among U.S. college students

Food and alcohol disturbance (FAD) refers to the intersection of alcohol- and eating-related motives and behaviors, such as restricting food intake before or during alcohol use to offset caloric intake or to enhance intoxication. Valid assessment is critical for advancing research on FAD. We tested the factor structure, group invariance, and concurrent validity of the College Eating and Drinking Behavior Scale (CEDBS) in a large college student sample (n = 2610; Mage = 20.95, SD = 4.65; 71.8% female; 77% White; 86% non-Hispanic). Participants completed measures assessing antecedents of alcohol use (i.e., protective behavioral strategies and drinking motives), negative alcohol-related consequences, alcohol use severity, and risk for eating disorder. The 3-factor model of the 21-item CEDBS provided an adequate fit to the data (e.g., CFI = 0.916). These factors include Alternative Methods (4 items; "Use laxative prior to drinking alcohol"), Offset Calories (7 items; "Restrict calories prior to drinking to help maintain your figure"), and Quicker Intoxication (10 items; "Not eating before drinking alcohol because it gives you the best buzz"). The CEDBS was scalar invariant across subgroups of participants based on age, sex, race/ethnicity, socioeconomic status, sexual orientation, and political orientation. Quicker Intoxication was most strongly related to risk factors and negative consequences for alcohol (r = 0.204-0.379, all ps < 0.01), and Offset Calories was most strongly related to risk for eating disorders (r = 0.349, p < .01). These findings further support the CEDBS to assess FAD among college students.

Projected impact of anti-obesity pharmacotherapy use on racial and ethnic disparities in adolescent obesity

BACKGROUND

Paediatric obesity disproportionately impacts individuals from minoritized racial and ethnic backgrounds. Recent guidelines support use of anti-obesity pharmacotherapy for adolescents with obesity, but the potential impact on disparities in obesity prevalence has not been evaluated.

OBJECTIVES

To model changes in obesity prevalence with increasing utilization of anti-obesity pharmacotherapy among adolescents.

METHODS

Data representative of American adolescents ages 12-17 years were obtained from the National Health and Nutrition Examination Survey, cycles 2011 through pre-pandemic 2020. A body mass index (BMI) reduction of 16.7% was applied to each participant based on clinical trial results of weekly subcutaneous semaglutide 2.4 mg among adolescents. Utilization disparities were based on utilization of the same medication class among adults. Obesity prevalence was calculated assuming utilization of 10%-100%, stratified by race and ethnicity.

RESULTS

Among 4442 adolescents representing 26 247 384 American adolescents, projected overall obesity prevalence decreased from 22.2% to 8.4% with 100% utilization. However, disparities increased relative to Non-Hispanic White youth, with prevalence among Non-Hispanic Black and Mexican American youth ranging from 40%-60% higher to 90%-120% higher, respectively.

CONCLUSIONS

Increasing utilization of anti-obesity pharmacotherapy may widen relative disparities in obesity, particularly if utilization is unequal. Advocacy for equitable access is needed to minimize worsening of obesity-related disparities.

Family Meals and Social Eating Behavior and Their Association with Disordered Eating among Spanish Adolescents: The EHDLA Study

PURPOSE

The aim of this study was to examine the association of family meals and social eating behavior with disordered eating behavior in Spanish adolescents.

METHODS

This was a cross-sectional study that included 706 adolescents (43.9% boys) from the Eating Habits and Daily Life Activities (EHDLA) study (aged 12 to 17) from Valle de Ricote, Region of Murcia, Spain. The frequency of family meals was assessed by asking participants to report how often their family, or most household members, had shared meals in the past week. Social eating behavior was evaluated using three statements: "I enjoy sitting down with family or friends for a meal", "Having at least one meal a day with others (family or friends) is important to me", and "I usually have dinner with others". To evaluate disordered eating, two psychologists administered the Sick, Control, One, Fat and Food (SCOFF) questionnaire.

RESULTS

After adjusting for several covariates, for each additional family meal, the likelihood of having disordered eating behavior was lower (odds ratio (OR) = 0.96; 95% confidence interval (CI) 0.93 to 0.9997, p = 0.049). On the other hand, a lower likelihood of having disordered eating behavior was observed for each additional point in the social eating behavior scale (OR = 0.85; 95% CI 0.77 to 0.93, p = 0.001). The likelihood of having disordered eating behavior was 0.7% lower for each additional family meal (95% CI 0.01% to 1.4%, p = 0.046). Furthermore, for each additional point in the social eating behavior scale, a lower probability of having disordered eating behavior was observed (3.2%; 95% CI 1.4% to 5.0%, p < 0.001).

CONCLUSIONS

While disordered eating behavior is complex and can be shaped by various factors, both family meals and social eating behavior emerge as significant factors inversely associated with this condition among adolescents. Promoting regular engagement in family meals and fostering positive social eating experiences could serve as effective strategies in public health initiatives aimed at mitigating the incidence of disordered eating behavior among the young population.

The need for more inclusive measurement to advance equity in eating disorders prevention

Eating disorder (ED) research and practice have been shaped by prevailing stereotypes about who EDs are most likely to affect. Subsequently, the field has prioritized the needs and concerns of affluent, cisgender, heterosexual, white girls and women to the exclusion of others, especially people marginalized based on their race, ethnicity, sexual orientation, and/or gender identity. However, EDs exist across diverse groups and actually occur with elevated prevalence in several marginalized groups. Growing research points to differences in the drivers of EDs in such groups (e.g. desire to attain the curvy rather than thin ideal; dietary restraint due to food insecurity rather than weight/shape concerns), yet tools typically used for screening and intervention evaluation do not capture eating pathology driven by such factors. In this commentary, we describe gaps in existing ED assessment tools and argue these gaps likely underestimate EDs among marginalized groups, bias who is invited, participates in, and benefits from ED prevention programs, and obscure potential group differences in the efficacy of such programs. We also discuss the potential of these ramifications to exacerbate inequities in EDs. Finally, we outline recommendations to overcome existing gaps in measurement and, consequently, advance equity in the realm of ED prevention.

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.

Let's get aligned! Developing a core outcome set for clinical trials in eating disorders

OBJECTIVE

Our study aimed to review the outcome measures/assessment instruments used and to assess their heterogeneity/homogeneity in eating disorders (EDs) randomised controlled trials.

METHODS

APA PsycInfo, PubMed, and Embase were searched in December 2022 to identify studies published between and inclusive of January 2012 and December 2022. Inclusion/exclusion criteria were: (1) complete articles published in peer-reviewed scientific journals, which were: (2) randomised trials, (3) in a clinical setting (4) with human subjects, (5) with an ICD or DSM diagnosis of Anorexia Nervosa, Binge Eating Disorder, or Bulimia Nervosa. The selected papers also: (6) used one or more standardised instruments designed to measure one or more psychometric characteristics associated with ED as a primary or secondary outcome, as judged by the authors of this systematic review, and (7) were published in English or Danish.

RESULTS

Ninety one articles were included, and a total of 196 outcome measures were collected.

DISCUSSION

The diversity of outcome measures in ED trials hampers result comparability and data integration. We suggest creating a core outcome measure set using the Delphi method, including clinician and patient-reported ED assessments, along with relevant comorbidity scales.

Improvements in Adolescents' Disordered Eating Behaviors in a Collaborative Care Digital Mental Health Intervention: Retrospective Observational Study

BACKGROUND

Young people today are exhibiting increasing rates of disordered eating behaviors, as well as eating disorders (EDs), alongside other mental and behavioral problems such as anxiety and depression. However, limited access to mental health care means that EDs, disordered eating behaviors, and comorbid mental health problems are often underdiagnosed and undertreated. Digital mental health interventions (DMHIs) offer accessible and scalable alternatives to traditional treatment modalities, but their effectiveness has not been well established among adolescents with EDs and disordered eating behaviors.

OBJECTIVE

This study uses data from a collaborative care pediatric DMHI to determine whether participation in a DMHI is associated with a reduction in adolescents' disordered eating behaviors.

METHODS

Adolescent members in care with Bend Health Inc completed the SCOFF questionnaire at baseline (before the start of care) and approximately every month during care to assess disordered eating behaviors. They also completed assessments of mental health symptoms at baseline. Member characteristics, mental health symptoms, and disordered eating behaviors of adolescents with elevated SCOFF scores at baseline (before the start of care) were compared to those of adolescents with nonelevated SCOFF scores at baseline. Members participated in web-based coaching or therapy sessions throughout the duration of mental health care.

RESULTS

Compared to adolescents with nonelevated SCOFF scores (n=520), adolescents with elevated SCOFF scores (n=169) were predominantly female and exhibited higher rates of elevated anxiety and depressive symptoms. SCOFF scores decreased over time in care with the DMHI for 61.4% (n=70) of adolescents with elevated SCOFF scores, and each additional month of participation was associated with greater improvements in disordered eating behaviors (F1,233=72.82; P<.001).

CONCLUSIONS

Our findings offer promising preliminary evidence that participation in mental health care with a collaborative care DMHI may be beneficial in the reduction of disordered eating symptoms in adolescents, including those who are experiencing comorbid anxiety and depressive symptoms.

The Prevalence of Disordered Eating Behaviours (DEBs) among Adolescent Female School Students in Riyadh, Saudi Arabia: A Cross-Sectional Study

Adolescence is a sensitive stage of life that is particularly vulnerable to nutritional problems, including DEBs. This cross-sectional study aims to explore the prevalence of DEBs among adolescent female school students in four intermediate and secondary schools in the city of Riyadh and to examine predictors associated with DEBs, including age, BMI and school regions. A total of 416 female students aged 12-19 years took part in this study. Weight and height were measured for students before the EAT-26 test was completed. Overweight and obesity were observed among 37.7% (n = 157) of students, 50.7% (n = 211) had a normal BMI and 11.5% (n = 48) were underweight. Results indicated that 123 (29.6%) students reported an EAT-26 score of 20 or more, indicating a high risk of DEB. Age was a significant predictor of DEB risk (OR = 3.087, 95% CI = 1.228-7.760), with the older age group (16-19 years) reporting a higher risk than the younger age group (12-15 years) (p = 0.017). DEB risk partially differed by school region, but BMI was not a statistically significant predictor. The high-risk group reported more binging (p = 0.008), induced vomiting (p < 0.001), laxative consumption (p < 0.001) and exercising (p < 0.001) compared with the low-risk group. Further research is warranted to understand DEB current patterns and predictors.

The Necessity or Not of Additional Endovascular Therapy to Medical Therapy for Symptomatic Intracranial Artery Stenosis: Insights from 30-Day and 1-Year Results

BACKGROUND

The optimal treatment between endovascular therapy and medical treatment for symptomatic intracranial artery stenosis is still unclear. This study aimed to compare the safety and efficacy of 2 treatments based on the results from currently published randomized controlled trials (RCTs).

METHODS

PubMed, Cochrane Library, EMBASE, and Web of Science were used for searching the RCTs evaluating the addition of endovascular therapy to medical therapy for treating symptomatic intracranial artery stenosis from the inception of these databases to September 30, 2022. P < 0.05 was considered statistically significant. All analyses were performed using STATA version 12.0.

RESULTS

A total of 4 RCTs were involved in the current study, including 989 participants. In the 30-day results, the data showed that compared with the medical therapy alone group, the additional endovascular therapy group was associated with a higher risk of death or stroke (relative risk (RR): 2.857; 95% confidence interval (CI): 1.756-4.648; P < 0.001), ipsilateral stroke (RR: 3.525; 95% CI: 1.969-6.310; P < 0.001), death (risk differences (RD): 0.01; 95% CI: 0.004-0.03; P = 0.015), hemorrhagic stroke (RD: 0.03; 95% CI: 0.01-0.06; P < 0.001), and ischemic stroke (RR: 2.221; 95% CI: 1.279-3.858; P = 0.005). In the 1-year results, the additional endovascular therapy group was related to a greater incidence of ipsilateral stroke (RR, 2.247; 95% CI, 1.492-3.383; P < 0.001) and ischemic stroke (RR: 2.092; 95% CI: 1.270-3.445; P = 0.004).

CONCLUSIONS

Given that the medical treatment alone was related to a lower risk of stroke and death in the short-term and long-term compared with endovascular therapy combined with medical therapy. Based on this evidence, these findings do not support the addition of endovascular therapy to medical therapy for treating patients with symptomatic intracranial stenosis.

Attention-deficit hyperactivity disorder is associated with disordered eating in adolescents

AIM

Attention-deficit hyperactivity disorder (ADHD) and disordered eating (DE) are both highly prevalent among adolescents, but their relationship is understudied. This study examines their possible association in a nationally representative sample of adolescents.

METHODS

Participants in the Israeli Youth Health and Nutrition Survey (2015-2016), a cross-sectional, school-based study, completed self-administered questionnaires, including the SCOFF questionnaire, and underwent anthropometric measurements. An affirmative reply to at least two SCOFF items was considered a DE case. Multivariable logistic regression evaluated the ADHD-DE association and the associations between ADHD and individual SCOFF items, controlling for age, sex, socioeconomic status, and body mass index.

RESULTS

Of 4616 participants (12-18 years, 50.2% male), 654 reported an ADHD diagnosis. DE prevalence among ADHD adolescents was significantly higher than the non-ADHD group (50.2% vs. 43.9%, p = 0.003). Controlling for potential covariates, the association between ADHD and DE remained significant (OR = 1.409; 95% CI: 1.170-1.697), as did associations between ADHD and three SCOFF items. No difference in DE prevalence was found between stimulant-treated (n = 287) and untreated (n = 326) adolescents with ADHD.

CONCLUSION

Adolescents with ADHD are more likely to experience DE. As DE can herald an imminent eating disorder, early identification is crucial. Further studies are needed to determine the ADHD-DE relationship's causality.

IMPACT

Disordered eating (DE) and attention-deficit hyperactivity disorder (ADHD) are common among adolescents, and significantly affect health and well-being. This study examined the association between ADHD and DE in adolescents using the SCOFF questionnaire. Following adjustment for sociodemographic variables and BMI z-score, ADHD was associated with a 41% increased odds for DE. This study established the association between ADHD and DE, using a well-known questionnaire, in a large, nationally representative sample of adolescents. Monitoring eating behaviors and attitudes among adolescents with ADHD should be a priority, to minimize the risk of developing an eating disorder and its harmful consequences.

The Role of Cdc42 in the Insulin and Leptin Pathways Contributing to the Development of Age-Related Obesity

Age-related obesity significantly increases the risk of chronic diseases such as type 2 diabetes, cardiovascular diseases, hypertension, and certain cancers. The insulin-leptin axis is crucial in understanding metabolic disturbances associated with age-related obesity. Rho GTPase Cdc42 is a member of the Rho family of GTPases that participates in many cellular processes including, but not limited to, regulation of actin cytoskeleton, vesicle trafficking, cell polarity, morphology, proliferation, motility, and migration. Cdc42 functions as an integral part of regulating insulin secretion and aging. Some novel roles for Cdc42 have also been recently identified in maintaining glucose metabolism, where Cdc42 is involved in controlling blood glucose levels in metabolically active tissues, including skeletal muscle, adipose tissue, pancreas, etc., which puts this protein in line with other critical regulators of glucose metabolism. Importantly, Cdc42 plays a vital role in cellular processes associated with the insulin and leptin signaling pathways, which are integral elements involved in obesity development if misregulated. Additionally, a change in Cdc42 activity may affect senescence, thus contributing to disorders associated with aging. This review explores the complex relationships among age-associated obesity, the insulin-leptin axis, and the Cdc42 signaling pathway. This article sheds light on the vast molecular web that supports metabolic dysregulation in aging people. In addition, it also discusses the potential therapeutic implications of the Cdc42 pathway to mitigate obesity since some new data suggest that inhibition of Cdc42 using antidiabetic drugs or antioxidants may promote weight loss in overweight or obese patients.

Overall proportion of orthorexia nervosa symptoms: A systematic review and meta-analysis including 30 476 individuals from 18 countries

Background

To date, no previous meta-analysis has determined the overall proportion of orthorexia nervosa symptoms on a global scale. The aim of the present study was 2-fold: first, to establish the overall proportion of orthorexia nervosa symptoms on a global scale, assessed with the ORTO-15 questionnaire; and second, to determine the role of sex, type of population, mean age, body mass index, and the temporal trend in relation to orthorexia nervosa symptoms.

Methods

Four databases were searched (PubMed, Scopus, Web of Science, and Cochrane Database of Systematic Reviews) with date limits from January 2005 to June 2023. Studies assessing the proportion of orthorexia nervosa assessed using the ORTO-15 questionnaire with a cutoff of <35 or <40 points were included in this review.

Results

The overall proportion of orthorexia nervosa symptoms (using the cutoff <35 points) was 27.5% (95% confidence interval (CI) = 23.5-31.6, I2 = 97.0%). In addition, no significant differences were observed between females (34.6%, 95% CI = 29.5-39.8, I2 = 96.1%) and males (32.1%, 95% CI = 26.5-38.1, I2 = 93.1%). According to the type of population, the highest overall proportion was found in people focused on sports performance or body composition (34.5%, 95% CI = 23.1-47.0, I2 = 98.0%). Notwithstanding, caution should be exercised in interpreting this result, as reverse causality could be a potential pitfall in this relationship.

Conclusions

We found that approximately three out of 10 study participants showed orthorexia nervosa symptoms according to the ORTO-15 tool. This overall proportion was higher in those participants who were athletes or fitness practitioners. Over the years, the proportion of orthorexia nervosa symptoms seems to be increasing. These high percentages and their increase are worrisome from a public health perspective and highlight the need to develop psychometric instruments to aid in clinical diagnosis and treatment efficacy.

Eating disorders and physical multimorbidity in the English general population

PURPOSE

People with eating disorders may be at increased risk for physical health problems, but there are no data on the relationship between eating disorders and physical multimorbidity (i.e., ≥ 2 physical conditions) and its potential mediators. Thus, we investigated this association in a representative sample of adults from the UK, and quantified the extent to which this can be explained by various psychological and physical conditions, and lifestyle factors.

METHODS

Cross-sectional data of the 2007 Adult Psychiatric Morbidity Survey were analyzed. Questions from the five-item SCOFF screening instrument were used to identify possible eating disorder. Respondents were asked about 20 physical health conditions. Multivariable logistic regression and mediation analysis were conducted.

RESULTS

Data on 7403 individuals aged ≥ 16 years were analyzed [mean (SD) age 46.3 (18.6) years; 48.6% males]. After adjustment, possible eating disorder was associated with 2.11 (95%CI = 1.67-2.67) times higher odds for physical multimorbidity. Anxiety disorder explained the largest proportion this association (mediated percentage 26.3%), followed by insomnia (21.8%), perceived stress (13.4%), depression (13.1%), obesity (13.0%), and alcohol dependence (4.3%).

CONCLUSION

Future longitudinal studies are warranted to understand potential causality and the underlying mechanisms in the association between eating disorder and multimorbidity, and whether addressing the identified potential mediators in people with eating disorders can reduce multimorbidity.

Population-level policy recommendations for the prevention of disordered weight control behaviors: A scoping review

OBJECTIVE

The aim of this scoping review was to identify recommendations and gaps in knowledge surrounding the prevention of disordered weight control behaviors (DWCBs) through policy.

METHOD

A search was conducted in several databases to identify English language articles that described an active policy, recommendation, guideline, or educational curriculum that could be implemented by governments or regulatory bodies to prevent DWCBs or related constructs (e.g., weight stigma, body dissatisfaction). Two researchers independently screened articles with oversight from a third researcher. Data were extracted from the final sample (n = 65) and analyzed qualitatively across all articles and within the domains of education, public policy, public health, industry regulation, and media.

RESULTS

Only a single empirical evaluation of an implemented policy to reduce DWCBs was identified. Over one-third of articles proposed recommendations relating to industry regulation and media (n = 24, 36.9%), followed by education (n = 21, 32.3%), public policy (n = 19, 29.2%), and public health (n = 10, 15.4%). Recommendations included school-based changes to curricula, staff training, and anti-bullying policies; legislation to ban weight discrimination; policies informed by strategic science; collaboration with researchers from other fields; de-emphasizing weight in health communications; diversifying body sizes and limiting modified images in media; and restricting the sale of weight-loss supplements.

DISCUSSION

The findings of this review highlight gaps in empirically evaluated policies to reduce DWCBs but also promising policy recommendations across several domains. Although some policy recommendations were supported by empirical evidence, others were primarily based on experts' knowledge, highlighting the need for greater research on population-level DWCBs prevention through policy.

PUBLIC SIGNIFICANCE

Our scoping review of the evidence on policies for the prevention of disordered weight control behaviors identified several recommendations across the domains of education, public policy, public health, and industry regulation and media. Although few empirical investigations of implemented policies have been conducted, expert recommendations for policies to prevent disordered weight control behaviors among populations are plentiful and warrant future consideration by researchers and policymakers alike.

Temporal associations between experiential avoidance and disordered eating behaviors in adolescents and young adults: findings from an epidemiological cohort study with ecological momentary assessment

PURPOSE

Previous studies linking experiential avoidance (EA) and eating pathology have largely relied on single measurements based on traditional retrospective questionnaires. Taking advantage of available repeated assessments of EA and disordered eating behaviors (DEBs) in the everyday lives of young people from an epidemiological cohort, we aimed to investigate ecologically valid temporal associations between these constructs.

METHODS

A random population sample of N = 1180 14-21-year-olds from Dresden, Germany, participated at baseline (2015/2016). As part of smartphone-based ecological momentary assessment (EMA), participants reported on engagement in EA and four DEBs (skipping eating, eating large amounts of food, loss-of-control eating, and restrained eating) up to eight times per day for four days. Multilevel modeling of concurrent and time-lagged associations between EA and DEBs, was conducted among those with at least 50% EMA-compliance (n = 1069).

RESULTS

EA was associated with higher concurrent levels of all four types of concurrent DEBs. In addition, EA significantly predicted subsequent levels of restrained eating. Only loss-of-control eating significantly predicted subsequent EA, and this effect depended on the timespan between consecutive assessments. When this timespan was short, higher Loss-of-control eating predicted lower subsequent EA, while it predicted higher subsequent EA when the timespan was longer.

CONCLUSION

The present findings suggest that EA is temporally closely linked to greater engagement in DEBs, supporting theoretical assumptions that DEBs may serve an attempted avoidance function in the context of unpleasant inner experiences. Future studies may benefit from examining samples with more pronounced eating pathology.

LEVEL OF EVIDENCE

Level IV: Evidence obtained from multiple time series with or without the intervention, such as case studies.

The Comparison of Disordered Eating, Body Image, Sociocultural and Coach-Related Pressures in Athletes across Age Groups and Groups of Different Weight Sensitivity in Sports

The aim of the present study was to compare disordered eating (DE), body image, and sociocultural and coach-related pressures between athletes of different age groups (adolescents and adults) and between athletes participating in weight-sensitive (WS) and less WS groups. A total of 1003 athletes participated in this study. The age range of the sample was 15 to 44 years, and the mean age was 18.9 ± 5.8 years (51.3% were female). Athletes who voluntarily agreed to participate in the study were provided with the study measures on DE, body image and sociocultural attitudes towards appearance. Vomiting, laxative misuse and excessive exercise were more prevalent in adolescent female athletes than adults, while dietary restraint was more common in adult male athletes than adolescents. Adolescent female athletes experienced higher sociocultural (family, peers) and sport-related (coach) pressures and a less positive body image compared with adult female athletes. Adult male athletes experienced higher overweight preoccupation, more DE and unhealthy eating habits, and engaged in more frequent self-weighing behaviour compared with adolescent males. When the effect of weight sensitivity in sports was tested, a higher prevalence of DE and overweight preoccupation, more frequent self-weighing, and higher body-image-related pressure from coaches were observed in female athletes participating in aesthetic weight-sensitive (WS) sports as compared with those participating in less WS sports. No differences in positive body image were observed in female WS and less WS sports. Special DE prevention and positive body image promotion programs are necessary for female competitive athletes and parents of adolescent female athletes, especially those participating in aesthetic ones. For adult male athletes, special programs aiming to promote healthy eating should be implemented to prevent DE and body image concerns. Special education about DE prevention is compulsory for coaches who train female athletes.

Prevalence of Disordered Eating and Its Associated Factors From a Socioecological Approach Among a Sample of Spanish Adolescents: The EHDLA Study

Objectives: The aim of this study was twofold: a) to establish the prevalence of adolescents with disordered eating and b) to determine the factors associated with this prevalence in a sample of Spanish adolescents from the Valle de Ricote (Region of Murcia, Spain).

Methods: This cross-sectional study analyzed data from 730 adolescents (56.2% girls) from the EHDLA study. To determine the prevalence of disordered eating, the Sick, Control, One stone, Fat, Food (SCOFF) questionnaire was used. A socioecological approach was used to identify individual-, interpersonal-, or organizational-level factors associated with disordered eating.

Results: The prevalence of disordered eating was 30.1%. This condition was associated with female sex (odds ratio [OR] = 2.60; 95% confidence interval [CI], 1.81–3.73), immigrant status (OR = 2.22; 95% CI, 1.51–3.25), or excess weight (OR = 2.74; 95% CI, 1.93–3.89). Furthermore, for each additional hour slept, lower odds of having disordered eating were found (OR = 0.81; 95% CI, 0.67–0.98).

Discussion: Almost one-third of the sample of Spanish adolescents analyzed reported disordered eating. Female sex, immigrant status and excess weight are individual aspects that seem to be related to disordered eating among Spanish adolescents.

Effects of Socioeconomic Environment on Physical Activity Levels and Sleep Quality in Basque Schoolchildren

The socioeconomic and built environment of an area are interrelated with health data and have a direct influence on children’s development. There are facilitators and barriers for schools to promote physical activity depending on the socioeconomic status of the school. The aim of this study was to analyse the relationship between physical activity and sleep and the socioeconomic level of children in the Basque Country. The sample consisted of 1139 schoolchildren between the ages of six and seventeen (566 boys and 573 girls) from 75 schools (43 public and 32 private). Differences between groups were compared using the Mann–Whitney U test (two samples), Kruskal–Wallis one-factor ANOVA (k samples), and Spearman’s Rho correlation. There are sex differences in light (200.8 ± 62.5 vs. 215.9 ± 54.7) and moderate (69.0 ± 34.3 vs. 79.9 ± 32.1) physical activity in favour of the female group of higher socioeconomic status compared to male group of higher socioeconomic status. In the case of vigorous physical activity, the female group performed less than the male group across all socioeconomic statuses, which was statistically significant in the groups of high socioeconomic status (11.6 ± 9.3 vs. 6.9 ± 5.7) in group 2 and medium socioeconomic status (11.1 ± 9.3 vs. 7.7 ± 6.1) in group 3. There is an inverse relationship between sedentary behaviour and BMI, total bed time, total sleep time, and night-time awakenings. There is also an inverse relationship between all levels of physical activity performed with respect to BMI and total sleep efficiency. These data point towards notable inequalities in physical activity and daily sleep in Basque schoolchildren, which in turn may be marginalised in our current school system due to the effects of the socioeconomic environment.
