The hidden burden of eating disorders : an extension of estimates from the Global Burden of Disease Study 2019

Background: Anorexia nervosa and bulimia nervosa are the only eating disorders included in the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, yet binge-eating disorder and other specified feeding or eating disorder (OSFED) are more prevalent. This study sought to estimate the prevalence and burden of binge-eating disorder and OSFED globally and present a case for their inclusion in GBD. Methods: We sourced studies from the GBD 2019 anorexia nervosa and bulimia nervosa epidemiological databases, two systematic reviews that included studies with epidemiological estimates of binge-eating disorder and OSFED, and experts in the field. Studies, published between Jan 1, 1998, and March 1, 2019, were included if they reported non-zero prevalence of two or more eating disorders (anorexia nervosa, bulimia nervosa, binge-eating disorder, or OSFED) and diagnosed cases according to DSM-IV or DSM-5. The proportions of total eating disorder cases that met diagnostic criteria for each individual eating disorder were estimated via network meta-regression and simulation using studies reporting eating disorder prevalence. The global cases unrepresented in GBD 2019 were estimated using the proportions from the simulation and the GBD 2019 eating disorder prevalence. Disability weights for binge-eating disorder and OSFED were then estimated along with disability-adjusted life-years (DALYs). Estimates are presented with 95% uncertainty intervals (UIs). Findings: 54 studies, of which 36 were from high-income countries, were included in the analysis. The number of global eating disorder cases in 2019 that were unrepresented in GBD 2019 was 41·9 million (95% UI 27·9–59·0), and consisted of 17·3 million (11·3–24·9) people with binge-eating disorder and 24·6 million (14·7–39·7) people with OSFED (vs 13·6 million [10·2–17·5] people with eating disorders in GBD 2019). Together, binge-eating disorder and OSFED caused 3·7 million (95% UI 2·0–6·5) DALYs globally, bringing the total eating disorder DALYs to 6·6 million (3·8–10·6) in 2019. Interpretation: Binge-eating disorder and OSFED accounted for the majority of eating disorder cases and DALYs globally. These findings warrant the inclusion of binge-eating disorder and OSFED in future iterations of GBD, which will bring the burden experienced by people living with these disorders to the attention of policy makers with the means to target this burden.

Associations between parents' body weight/shape comments and disordered eating amongst adolescents over time : a longitudinal study

Parents are key influencers of adolescents’ attitudes on weight, shape, and eating, and make more positive than negative comments, with negative comments most impactful. This study examined prospective unique associations of parental positive and negative comments in a community sample of adolescents with paediatric psychosocial quality of life (PED-QoL), Eating Disorder Weight/Shape Cognitions (EDEQ-WS), BMI percentile, and Psychological Distress (K10) scales. Data were from 2056 adolescents from the EveryBODY study cohort. Multiple regressions were conducted for the impacts of parental positive and negative comments on four dependent variables at one year after controlling for their stage of adolescence (early, middle, late). Multiple imputation and bootstrapping were used for handling missing data and violations of normality. Results indicated that positive maternal comments on eating were associated with increased EDCs and better quality of life at one year. Paternal positive weight shape comments were associated with a decrease in psychological distress, but positive eating comments saw a decrease in quality of life. Findings highlight the nuances of parental comments and how these are perceived and interpreted, and could alert health care workers and family practitioners who have weight, shape, and eating conversations to be aware of the potential influence of their communication

Development of transdiagnostic clinical risk prediction models for 12-month onset and course of eating disorders among adolescents in the community

Objective: To develop and internally validate risk prediction models for adolescent onset and persistence of eating disorders. Methods: N = 963 Australian adolescents (11–19 years) in the EveryBODY Study cohort completed online surveys in 2018 and 2019. Models were built to predict 12-month risk of (1) onset, and (2) persistence of a DSM-5 eating disorder. Results: Onset Model. Of the n = 687 adolescents without an eating disorder at baseline, 16.9% were identified with an eating disorder after 12 months. The prediction model was based on evidence-based risk factors for eating disorder onset available within the dataset (sex, body mass index percentile, strict weight loss dieting, history of bullying, psychological distress, weight/shape concerns). This model showed fair discriminative performance (mean AUC =.75). The most important factors were psychological distress, weight and shape concerns, and female sex. Diagnostic Persistence Model. Of the n = 276 adolescents with an eating disorder at baseline, 74.6% were identified as continuing to meet criteria for an eating disorder after 12 months. The prediction model for diagnostic persistence was based on available evidence-based risk factors for eating disorder persistence (purging, distress, social impairment). This model showed poor discriminative performance (mean AUC =.65). The most important factors were psychological distress and self-induced vomiting for weight control. Discussion: We found preliminary evidence for the utility of a parsimonious model for 12-month onset of an eating disorder among adolescents in the community. Future research should include additional evidence-based risk factors and validate models beyond the original sample. Public Significance: This study demonstrated the feasibility of developing parsimonious and accurate models for the prediction of future onset of an eating disorder among adolescents. The most important predictors in this model included psychological distress and weight and shape concerns. This study has laid the ground work for future research to build and test more accurate prediction models in diverse samples, prior to translation into a clinical tool for use in real world settings to aid decisions about referral to early intervention

Weight goals, disordered eating behaviors, and BMI trajectories in US young adults

BACKGROUND: Community sample data indicate that weight control efforts in young adulthood may have associations with greater increases in body mass index (BMI) over time. OBJECTIVE: To determine the prospective associations between weight goals and behaviors in young adults and BMI trajectories over 15-year follow-up using a nationally representative sample. DESIGN: Longitudinal cohort data collected from 2001 to 2018 of the National Longitudinal Study of Adolescent to Adult Health. PARTICIPANTS: Young adults aged 18–26 years old at baseline stratified by gender and BMI category. MAIN MEASURES: Predictors: weight goals, any weight loss/maintenance behaviors, dieting, exercise, disordered eating behaviors. Outcomes: BMI at 7- and 15-year follow-up. KEY RESULTS: Of the 12,155 young adults in the sample (54% female, 32% non-White), 33.2% reported a goal to lose weight, 15.7% to gain weight, and 14.6% to maintain weight. In unadjusted models, all groups have higher mean BMI at 7- and 15-year follow-up. In mixed effect models, goals to lose weight in men with BMI < 18.5 (5.94 kg/m2 ; 95% CI 2.58, 9.30) and goals to maintain weight in men with BMI ≥ 25 (0.44; 95% CI 0.15, 0.72) were associated with greater BMI increase compared to no weight goal. Engaging in disordered eating behaviors was associated with greater BMI increase in men with BMI < 18.5 (5.91; 2.96, 8.86) and women with 18.5 ≤ BMI < 25 (0.40; 0.16, 0.63). Dieting (− 0.24; − 0.41, − 0.06) and exercise (− 0.31; − 0.45, − 0.17) were associated with lower BMI increase in women with 18.5 ≤ BMI < 25. In women with BMI < 18.5, dieting was associated with greater BMI increase (1.35; 0.33, 2.37). CONCLUSIONS: Weight control efforts may have variable effects on BMI over time by gender and BMI category. These findings underscore the need to counsel patients on the effectiveness of weight control efforts and long-term weight management

O impacto dos programas de prevenção veiculados na mídia: a gravidez na adolescência

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.A presente pesquisa aborda questões referentes à gravidez na adolescência a partir da leitura do impacto dos programas de prevenção veiculados na mídia, de acordo com relatos de adolescentes grávidas inscritas no programa de pré-natal da Secretaria Municipal de Saúde, do município de Itaúna (MG). Foi traçado o perfil da adolescente grávida e descrita a sua relação com as diversas mídias no que diz respeito à baixa eficiência dos programas de prevenção veiculados nestas mídias. A partir de estudos já realizados, a atenção recaiu sobre algumas questões: 1) O que é educação para a saúde? 2) Por que a gravidez precoce é um problema de saúde pública? 3) Em que pontos falham os programas de prevenção da gravidez na adolescência, veiculados nas mídias? Os resultados demonstram que o modelo informacional não contribui para a aprendizagem que o processo educativo supõe. A informação sobre como prevenir a gravidez não impede as manifestações psicológicas comuns no período adolescente. Os resultados apontam, também, que os conflitos adolescentes são vivenciados com maior processo de readaptação, quando acompanhado de uma gravidez; que as adolescentes não planejavam as gravidezes, não usavam qualquer método anticoncepcional, apesar de conhecê-los; têm seu comportamento influenciável pelas mídias apesar de não legitimarem os programas de prevenção veiculados nela. Espera-se que os resultados possam contribuir no processo de construção de programas de prevenção, uma vez que retrata a possibilidade do uso da mídia como instrumento da educação. O conhecimento do perfil da adolescente que engravida, assim como a imagem criada pelas campanhas de prevenção da gravidez precoce deve facilitar a criação de sistemas mais eficientes, facilitando a elaboração de programas de saúde coerentes com a demanda real. Research that approaches referring questions to the pregnancy in the adolescence from the reading of the impact of the propagated programs of prevention in the medias, in accordance with stories of enrolled pregnant adolescents in the program of prenatal of the City department of Health, of the city of Itaúna(MG). The profile of the pregnant and described adolescent was traced its relation with the diverse medias in that it says respect to low the efficiency of the propagated programs of prevention in the medias. From carried through studies already, the attention fell again on some questions: 1) What it is education for the health? 2) Why the precocious pregnancy is a problem of public health? 3) Where points fail the programs of prevention of the pregnancy in the adolescence, propagated in the medias? The results demonstrate that the informacional model does not contribute for the learning that the educative process assumes. The information on as to prevent the pregnancy does not hinder the common psychological manifestations in the adolescent period. The results point, also, that the adolescent conflicts are lived deeply with bigger process of readjustment, when folloied of a pregnancy; that the adolescents did not plan the pregnancies, they did not use any contraceptive method, although to know them; they have its influenciável behavior for the medias although not to legitimize the propagated programs of prevention in. It focuses the proposal of the education for the health, the adolescent development and the recocious pregnancy, points with respect to the diverse medias as tool of the education. It presents one to seem on the profile of the pregnant adolescent and the impact of the pregnancy and the campaigns of propagated prevention of the regnancy in the medias

Exploring associations between positive and negative valanced parental comments about adolescents' bodies and eating and eating problems : a community study

Background: Adolescence is a time of rapid emotional and physical development when foundational self-concepts (including beliefs about one’s weight and shape) are established. Parents are key influencers of adolescent beliefs and behaviours. This study aimed to investigate associations between perceived positive and negative parental comments on weight/shape and eating, with sons’ and daughters’ psychological distress and eating disorder cognitions (EDCs). Methods: A representative mixed-sex sample of 2204 Australian adolescents (12–19 years) from the EveryBODY Study completed an online survey exploring eating behaviours, psychological wellbeing and experiences of parental comments regarding weight, shape and eating behaviours. Results: Correlation analyses revealed that adolescents’ reports of perceived positive parental comments on shape/ weight were significantly associated with lower psychological distress and EDCs only for daughters. All perceived negative parental comments on shape/weight or eating were associated with greater psychological distress and EDCs for both sons and daughters. In the final model of the regression analysis, only perceived parental negative shape/weight and maternal negative eating comments, adolescent stage and biological sex were significantly associated with EDCs. When known contributors such as BMI percentile and psychological distress were included in the regression model, adolescent stage and perceived negative paternal comments were no longer significantly associated with EDCs. Conclusions: Overall, results show perceived negative comments were associated with poorer adolescent mental health, both their specific EDCs and general distress. Findings highlight the importance of raising awareness of potential negative impacts within family systems of comments around weight/shape and eating in these key formative years

Screening, assessment and diagnosis in the eating disorders : findings from a rapid review

Background: Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and identify gaps relating to the screening, assessment, and diagnosis of eating disorders within Western healthcare systems. Methods: This paper forms part of a Rapid Review series scoping the evidence base for the field of eating disorders, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021–2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for studies published between 2009 and mid 2021 in English. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised through purposive sampling. Data from selected studies relating to Screening, Assessment and Diagnosis of eating disorders were synthesised and are disseminated in the current review. Results: Eighty seven studies were identified, 38% relating to screening and 62% to assessment and diagnosis. The majority of screening studies were conducted in university student samples, showing high prevalence but only modest improvements in help-seeking in those studies that followed up post-screen. In healthcare settings, clinicians continue to have difficulty identifying eating disorder presentations, particularly Binge Eating Disorder, Other Specified Feeding or Eating Disorders, and sub-threshold eating disorders. This is preceded by inadequate and frequently homogenous screening mechanisms and exacerbated by considerable personal and health-system barriers, including self-stigma and lack of resourcing. While all groups are at risk of delayed or no diagnosis, those at particular risk include LGBTQ+ and gender diverse individuals, individuals living in larger bodies, and males. Conclusions: A majority of individuals with eating disorders remain undiagnosed and untreated despite a high prevalence of these conditions and increased advocacy in recent years. Research into improving detection and clinician diagnostic skill is extremely limited. Innovative empirical research is strongly recommended to address significant individual and health-system barriers currently preventing appropriate and timely intervention for many
