Comparison between Physical Activity and Stress-Related Lifestyle between Orthorexic and Non-Orthorexic University Students: A Case-Control Study.

(1) Background: The literature regarding orthorexia nervosa (ON) has well documented the association with other mental disorders, such as obsessive-compulsive and eating disorders. However, the research has not taken into account stress-related behavior and the conduction of physical activity (PA), both structured and unstructured. (2) Methods: In this cross-sectional study, 165 students of the University of Parma (92 females and 74 males) aged between 18 and 49 years old (mean = 24.62 ± 4.81) were consecutively recruited. The ORTO-15 questionnaire was used to divide the total sample into a group without orthorexia (score > 40) and a group with orthorexia (score < 40). All subjects completed the P Stress Questionnaire, and specific items were extrapolated from the Eating Habits Structured Interview (EHSI) to investigate lifestyle, including structured and unstructured PA. (3) Results: Subjects with orthorexia represented 83% of the total sample and reported higher levels of stress-related risk behaviors (i.e., sense of responsibility (t = -1.99, p = 0.02), precision (t = -1.99, p = 0.03), stress disorders (t = -1.38, p = 0.05), reduced spare time (t = -1.97, p = 0.03), and hyperactivity (t = -1.68, p = 0.04)) and a higher frequency of PA (i.e., hours spent training in structured PA, daily (t = -1.68, p = 0.05), weekly (t = -1.91, p = 0.03), and monthly (t = -1.91, p = 0.03), the tendency to carry out physical exercise even if tired (t = -1.97, p = 0.02), and to adhere to unstructured PA (i.e., moving on foot or by bike rather than using transport (t = 1.27, p = 0.04)). (4) Conclusions: The results confirmed the presence of hyperactivity at a motor and behavioral level in people with orthorexia. Further studies are necessary to highlight the causality between ON, stress, and physical activity but it may be possible to hypothesize that "obsessive" physical exercise may not generate the benefits generally known by the literature.

Factors associated with food label use: focus on healthy aspects of orthorexia and orthorexia nervosa.

PURPOSE: This study aimed to investigate the potential relationships between the use of different section of food label, and healthy and pathological aspects of orthorexia among adults. METHODS: This cross-sectional study was conducted using an online survey (n = 1326). Inclusion criteria were being 19-64 years and graduated from at least primary school. Pregnant and lactating women were excluded. Data were collected using questionnaire including socio-demographic variables, lifestyle factors, body weight and height, frequency of reading different sections of food label ("always", "when buying a food for the first time", "when comparing similar packaged foods", "rarely", "never"), food label literacy, and Teruel Orthorexia Scale. Participants were categorized as nutrition facts panel-users, ingredients list-users or claim-users if they read at least one item from the relevant parts. RESULTS: The proportions of nutrition facts, ingredients list, and claims sections users were 72.3%, 76.3%, and 79.9%, respectively. Both healthy and pathological aspects of orthorexia were associated with reading food labels. The healthy orthorexia had the strongest association with using the ingredients list (OR 1.76, 95% CI 1.41-2.20), whereas the orthorexia nervosa showed the highest association with using nutrition facts panel (OR 1.48, 95% CI 1.20-1.81). While women, physically active participants and those with higher food label literacy were more likely to use all sections of food labels; older age, having children, and chronic disease increased the likelihood of using claims and ingredients list (p < 0.05). Besides, following a diet was associated with higher use of nutrition facts and ingredients list (p < 0.05). CONCLUSIONS: The study demonstrates that food label users have higher orthorexia tendencies compared to non-users. Of the food label sections, healthy orthorexia showed the strongest association with use of the list of ingredients, while pathological orthorexia showed the strongest association with use of the nutrition facts panel. LEVEL OF EVIDENCE: Level V, cross-sectional study.

Orthorexia Nervosa and Healthy Orthorexia in a Physically Active North American Population.

The Teruel Orthorexia Scale (TOS) defines two related but distinct constructs: Orthorexia Nervosa (OrNe), a pathological fixation on a healthy diet, and Healthy Orthorexia (HeOr), an interest in a healthy diet independent of psychopathology. Here, we (a) assessed both types of Orthorexia in a large North American sample using the TOS and (b) explored if engaging in regular physical activity was associated with a greater risk of Orthorexia. A cohort of physically active adults (n = 927; 41% men) completed the TOS, as well as the Rapid Assessment of Physical Activity (RAPA), to broadly assess aerobic physical activity level and participation in strength and/or flexibility training. As expected, scores for HeOr and OrNe differed between participants, with lower scores for Orthorexia Nervosa in our physically active non-clinical sample. Higher HeOr scores were associated with lower BMI, and this was true for both men and women. We also found that measures of Orthorexia were associated with self-reported physical activity: active adults reporting more aerobic physical activity had higher HeOr scores, with the most active men having the highest scores. Notably, adults who reported regular strength training had higher scores for both HeOr and OrNe, with men who strength trained showing higher OrNe scores than women. Here, those who participate in regular strength training are more likely to exhibit orthorexic behaviors, and this effect was more pronounced for men than women. Prior work has validated the TOS in young, primarily female samples of non-English speakers outside the United States: present data from an age-diverse, physically active, gender balanced sample support the use of TOS for measurement of Orthorexia Nervosa and Healthy Orthorexia in English speakers and suggest that more work is needed to assess potential gender differences in these constructs.

Eating Disorder Symptomatology Among Young Adult Cigarette and E-Cigarette Users.

Objective: Tobacco use is elevated among individuals with eating disorders (EDs). Yet, further research is needed to understand associations between cigarette and e-cigarette use patterns and ED symptomatology. To gain a more comprehensive understanding of tobacco use and EDs, this study characterized ED symptomatology and tobacco use patterns, including exclusive cigarette use, e-cigarette use, dual use, and nonuse. Method: Young adults aged 18-24 years who self-reported exclusive cigarette, e-cigarette, dual, or nonuse (N = 2500) were recruited via Lucid, an online survey management company. Participants completed questionnaires assessing body dissatisfaction, global ED psychopathology, binge eating and self-induced vomiting frequency, and demographics. ED diagnostic groups included: anorexia nervosa (AN), bulimia spectrum eating disorders (BSED), atypical AN, and night eating syndrome (NES). Results: Multinomial logistic models revealed those with AN were more likely to be dual users, those with atypical AN were more likely to be exclusive e-cigarette users, and participants with a BSED or NES were more likely to be exclusive e-cigarette or dual users, compared to those without an ED. General linear models suggested body dissatisfaction and global ED psychopathology were higher among exclusive e-cigarette and dual users, while binge eating and self-induced vomiting frequencies were greater among all tobacco use groups compared to nonusers. Discussion: Our findings suggest young adults with ED symptomatology were more likely to be users of e-cigarettes exclusively or dual users. It will be necessary to examine how these associations manifest using longitudinal and clinical populations in future research.

Profiles of disordered eating behaviour in type 1 diabetes using the DEPS-R and behaviour and glycaemic outcomes in a real-life setting.

AIMS: The Diabetes Eating Problems Survey - Revised (DEPS-R) is commonly used to assess disordered eating behaviour (DEB) in individuals with type 1 diabetes and has advantages compared to other measures not specifically tailored to diabetes. A score ≥20 on the DEPS-R is used to indicate clinically significant DEB; however, it does not distinguish between eating disorder (ED) phenotypes necessary to guide treatment decisions, limiting clinical utility. METHODS: The current study used latent class analysis to identify distinct person-centred profiles of DEB in adults with type 1 diabetes using the DEPS-R. Analysis of Variance with Games Howell post-hoc comparisons was then conducted to examine the correspondence between the profiles and binge eating, insulin restriction and glycaemic control (HbA1c, mean blood glucose, and percent time spent in hyperglycaemia) during 3 days of assessment in a real-life setting. RESULTS: Latent class analysis indicated a 4-class solution, with patterns of item endorsement suggesting the following profiles: Bulimia, Binge Eating, Overeating and Low Pathology. Differences in binge eating, insulin restriction and glycaemic control were observed between profiles during 3 days of at-home assessment. The Bulimia profile was associated with highest HbA1c and 3-day mean blood glucose. CONCLUSIONS: There are common patterns of responses on the DEPS-R that appear to reflect different ED phenotypes. Profiles based on the DEPS-R corresponded with behaviour in the real-life setting as expected and were associated with different glycaemic outcomes. Results may have implications for the use of the DEPS-R in research and clinical settings.

Disordered Eating in Young Women with Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) was the most prevalent endocrine disorder among women. Weight issues were commonly observed and found to be associated with comorbidities. This study aimed to compare Eating Disorder Examination Questionnaire (EDE-Q) scores and Night Eating Questionnaire (NEQ) scores in patients with and without PCOS and analyze the factors associated with disordered eating. Women aged 18-25 years with and without PCOS (n = 110 for each group) were included in the study. All patients completed the EDE-Q, NEQ, Beck Anxiety, and Beck Depression inventories. Disordered eating was found more frequently in women with PCOS than in controls (25.5% vs. 2.7%, p < 0.001). There were no significant differences in NEQ scores between the two groups. Anxiety and depression scores were higher in patients with PCOS than in controls (p = 0.002 and p = 0.001, respectively). PCOS diagnosis (OR: 7.4, CI: [1.63-33.7]; p = 0.010) and high BMI (OR: 1.24, CI: [1.10-1.39]; p < 0.001) were found to be independent factors for disordered eating (EDE-Q global score ≥ 4). Disordered eating was more common in young women with PCOS compared to the control group. PCOS diagnosis and having a high BMI (> 25) were found to be independent factors related to disordered eating in young women with PCOS. Young women with a high BMI or PCOS appear to be at a higher risk of disordered eating than women of the same age. Scanning this group may help clinicians in identifying women at high risk for eating disorders and preventing comorbidities associated with them.

Daily ovarian hormone exposure and loss of control eating in adolescent girls: A registered report.

OBJECTIVE: The daily biobehavioral factors that precipitate loss of control eating (LOCE) in adolescent girls are not well known. Ovarian hormone levels are key biological factors associated with the etiology of eating disorders in adolescent girls. Yet, models on how daily ovarian hormone exposure predicts LOCE in adolescent girls are underdeveloped. The goal of this study is to examine the daily patterns and mechanisms of ovarian hormone levels on LOCE across the menstrual cycle in adolescent girls and the mediating roles of food-related reward anticipation and response inhibition. Ecological momentary assessment (EMA) paired with daily hormonal sampling will be used to examine (1) daily associations between within-person hormones and LOCE, and (2) the mediating role of within-person food-related reward anticipation and response inhibition. METHODS: Normally cycling adolescent girls who have reached menarche will provide daily saliva samples for hormone analysis and complete EMA for 35 days. During EMA, girls will report LOCE and will complete task-based and self-report measures of food-related response inhibition and reward anticipation. DISCUSSION: This work has implications for the development of new real-world biobehavioral models of LOCE in adolescent girls, which will guide theory improvements and treatment for LOCE. Results will provide preliminary evidence for treatment targets for novel interventions for adolescent girls-for example, a response inhibition intervention. PUBLIC SIGNIFICANCE: Adolescent eating disorders are severe mental health conditions, often marked by loss of control eating. Estrogen and progesterone play a role in the development and persistence of loss of control eating. The current study will examine how daily exposure to estrogen and progesterone predicts loss of control eating in adolescent girls and identify possible daily mechanisms linking estrogen and progesterone exposure and loss of control eating.

Determinants of disordered eating behaviors: Body mass index, emotional eating, dietary restriction, and motives for eating palatable foods / Determinantes de comportamentos alimentares desordenados: índice de massa corporal, alimentação emocional, restrição alimentar e motivos para comer alimentos palatáveis

ABSTRACT Objective: The study aimed to investigate the relationships between body mass index, reasons for consuming palatable foods, emotional eating, cognitive dietary restraint, and disordered eating behaviors in young adults. Methods: This study was conducted with 800 young adults, in Ankara, Türkiye. A questionnaire consisting of questions about socio-demographic characteristics, health status, and instruments including Eating Attitudes Test-26, Emotional Appetite Questionnaire, Palatable Eating Motives Scale, and The Three-Factor Eating Questionnaire were applied through face-to-face interviews. Results: According to the Eating Attitudes Test-26, 17.2% of males and 27.7% of females were at risk for disordered eating behaviors (χ2=9.750, p=0.002). The mean scores of the Three-Factor Eating Questionnaire-emotional eating, cognitive restraint subscales, and the positive and negative scores of the Emotional Appetite Questionnaire were higher in males than in females (p<0.05). The mean scores of the Palatable Eating Motives Scale-coping and reward enhancement motives were higher in females, while the mean score for the conformity motives was significantly higher in males. Body mass index, Three-Factor Eating Questionnaire-cognitive restraint subscale, Emotional Appetite Questionnaire-negative, and PEMS-conformity motives were found for predictors for Eating Attitudes Test-26 (all p<0.05). Conclusion: The results showed a high tendency for emotional eating, consumption of palatable foods, and cognitive dietary restraint in young adults, and these factors were considered determinants for eating disorders.

RESUMO Objetivo: O objetivo do estudo foi investigar as relações entre o índice de massa corporal, as razões para consumir alimentos palatáveis, o comer emocional, a restrição alimentar cognitiva e os comportamentos de desordem alimentar em jovens adultos. Métodos: Este estudo foi realizado com 800 jovens adultos, em Ancara, na Turquia. Foi aplicado um questionário composto por perguntas sobre características sociodemográficas, estado de saúde e instrumentos, incluindo o Eating Attitudes Test-26, o Emotional Appetite Questionnaire, a Palatable Eating Motives Scale e o The Three-Fator Eating Questionnaire, através de entrevistas presenciais. Resultados: De acordo com o Eating Attitudes Test-26, 17,2% dos homens e 27,7% das mulheres estavam em risco de desenvolver comportamentos alimentares desordenados (χ2=9,750, p=0,002). As pontuações médias do Three-Fator Eating Questionnaire-emotional eating, as subescalas de restrição cognitiva e as pontuações positivas e negativas do Emotional Appetite Questionnaire foram mais elevadas no sexo masculino do que no feminino (p<0,05). As pontuações médias da Palatable Eating Motives Scale - motivos de coping e de aumento da recompensa - foram mais elevadas no sexo feminino, enquanto a pontuação média para os motivos de conformidade foi significativamente mais elevada no sexo masculino. O índice de massa corporal, o Three-Fator Eating Questionnaire-subescala de contenção cognitiva, o Emotional Appetite Questionnaire-negativo e o PEMS-motores de conformidade foram encontrados como preditores do Eating Attitudes Test-26 (todos p<0,05). Conclusão: Os resultados mostraram uma elevada tendência para a alimentação emocional, o consumo de alimentos palatáveis e a restrição alimentar cognitiva em adultos jovens, sendo estes factores considerados determinantes para as perturbações alimentares.

Dificultades interpersonales en los trastornos alimentarios: un modelo psiconeurobiológico explicativo/comprensivo / Interpersonal difficulties in eating disorders: an explanatory/ comprehensive psychoneurobiological model

RESUMEN: Antecedentes: Los trastornos alimentarios (TCA) presentan entre sus síntomas disfunciones psicosociales como ansiedad social, alexitimia y falta de asertividad. Objetivo: Se propone un modelo explicativo/comprensivo que integra aspectos de psiconeurobiología y comportamiento útil para la clínica. Método: Se evaluó una revisión de la literatura en Medline / PubMed, SciELO y bases de datos de textos especializados con criterios de calidad. Fueron seleccionados conceptos centrales para construir una coherencia que permitiera la lectura psiconeurobiológica del fenómeno y su aplicación clínica. Resultados: Cuatro factores fueron dispuestos a significar: 1- sistema de alarma; 2- sistema de recompensa 3- cerebro social; 4-mecanismos de control (inhibición/excitación). Se dispusieron mostrando la complejidad de su interacción psicofisiológica. Se sugiere que la ingesta de alimentos podría funcionar como una forma primaria de equilibrio cuando hay fallas en alguno de los sistemas expuestos. Conclusión: Se presenta un modelo de integración psiconeurobiológico útil para explicar la dificultad interpersonal en TCA. Esta forma de comprensión facilita: la conexión entre las investigaciones emergentes en TCA y DI; la toma de decisiones clínicas y orientan el pronóstico y las alternativas de tratamiento.

ABSTRACT Background: Eating disorders (ED) are characterized by psychosocial disfunctions, like social anxiety, alexithymia and lack of assertiveness. Objective: To propose a comprehensive integrative model including neurobiology and behavior aspects. Method: A literature review on Medline/PubMed, SciELO and specialized texts databases were assessed against quality criteria. Core concepts were extracted and coherence articulated. Results: Four factors were disposed to meaning: alarm and reward system with social brain and control (inhibition/excitation) mechanisms. They were articulate in a complex psychophysiological interplay. They were associated with social behaviours achieved/not achieved during development. Food intake could operate like a pathological balance to psychopathological effects Conclusion: An explanatory/comprehensive psychoneurobiological model to understand social function in ED is proposed. This form of understanding facilitates: the connection between emerging research in eating disorders and ID; clinical decision-making and guide the prognosis and treatment alternatives.

Body image and disordered eating behaviors in Hispanic/Latino Youth: Findings from the Hispanic Community Health Study/Study of Latino Youth.

BACKGROUND: Prevalence of certain disordered eating behaviors is higher among Hispanic youth compared to non-Hispanics. Understanding the role of body image and social attitudes towards weight in disordered eating may inform treatment in Hispanic youth. METHODS: We analyzed data from the Hispanic Community Health Study/Study of Latino Youth (SOL Youth). Our sample included 1,463 children aged 8-16 years from four sites (Bronx, Chicago, Miami, San Diego) assessed in 2011-2014. Body image discrepancy score was calculated as the difference between perceived ideal body image and actual body image using two numbered visual graphs: adolescent (n = 728) or child (n = 735), each with slightly different scales. Questionnaires measured influences from social attitudes toward weight and disordered eating behaviors. Three disordered eating behaviors (dieting, overeating, and compensatory behaviors) were analyzed as the dependent variable. Logistic regression models adjusted for age, sex, acculturative stress, and field center to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI). RESULTS: Mean body image discrepancy score was -0.79 for adolescents (SE = 0.08) and -0.50 for children (SE = 0.05), with a negative score signifying a perceived actual body image larger than their ideal. Body image discrepancy was strongly associated with dieting (dieting ≥5 times/year aOR = 0.64, 95% CI 0.53, 0.77) and compensatory behaviors (aOR = 0.65, 95% CI 0.50, 0.85) among adolescents, and was strongly associated with overeating among children (aOR = 0.74, 95% CI 0.61, 0.91). Significant associations were not observed with social attitudes towards weight. CONCLUSIONS: Associations observed with body image discrepancy and disordered eating behaviors can inform interventions in Hispanic/Latino youth, which should consider acculturative stress.

Obesity and Eating Disorders in Children and Adolescents: The Bidirectional Link.

Obesity, eating disorders and unhealthy dieting practices among children and adolescents are alarming health concerns due to their high prevalence and adverse effects on physical and psychosocial health. We present the evidence that eating disorders and obesity can be managed or prevented using the same interventions in the pediatric age. In the presence of obesity in the pediatric age, disordered eating behaviors are highly prevalent, increasing the risk of developing eating disorders. The most frequently observed in subjects with obesity are bulimia nervosa and binge-eating disorders, both of which are characterized by abnormal eating or weight-control behaviors. Various are the mechanisms overlying the interaction including environmental and individual ones, and different are the approaches to reduce the consequences. Evidence-based treatments for obesity and eating disorders in childhood include as first line approaches weight loss with nutritional management and lifestyle modification via behavioral psychotherapy, as well as treatment of psychiatric comorbidities if those are not a consequence of the eating disorder. Drugs and bariatric surgery need to be used in extreme cases. Future research is necessary for early detection of risk factors for prevention, more precise elucidation of the mechanisms that underpin these problems and, finally, in the cases requiring therapeutic intervention, to provide tailored and timely treatment. Collective efforts between the fields are crucial for reducing the factors of health disparity and improving public health.

Trastorno de conducta alimentaria en adolescentes transgénero: modelo de intervención especializado / Eating disorders in adolescents with gender incongruence: review and specialized intervention mode

Las (os, es) adolescentes transgénero presentan trastorno de conducta alimentaria (TCA) entre otras condiciones asociadas y debe ser comprendida e intervenida adecuadamente por las(os) profesionales, ya que de lo contrario puede llevar a agravar la salud mental de esta población adolescente. MÉTODOS: Se realiza revisión de la literatura publicada en revistas científicas indexadas en PUBMED y Google Académico entre los años 2015 y 2021. RESULTADOS: Existen escasas publicaciones de esta co-ocurrencia en la literatura internacional e inexistente a nivel nacional, además de que no se describen modelos especializados de intervención. Como aspecto central de esta co-ocurrencia emerge la insatisfacción corporal con el desarrollo de los caracteres sexuales secundarios. Se observan diferencias en la presentación del TCA en mujer trans y hombre trans. Existen factores de riesgo a la base, particularmente estrés de minorías y factores protectores como el apoyo familiar. Se propone y describe un modelo de estadios, enfocado en la prevención, particularmente en los primeros signos de insatisfacción corporal. Un estadio de intervención que incorpora principalmente tratamiento médico afirmativo, el cual favorece la disminución de la insatisfacción corporal y finalmente como una última etapa el seguimiento de logros y apoyo en recaídas. CONCLUSIONES: En la evaluación e intervención es importante detectar a tiempo en la etapa puberal, incorporar tratamiento afirmativo médico, apoyar en factores protectores y de riesgo, no visualizar al TCA en esta población como una comorbilidad patológica y realizar seguimiento de recaídas.

Transgender adolescents present eating disorders (ED), among other associated conditions, and professionals must suitably understand and intervene; otherwise, this can worsen the mental health of this adolescent population. METHODS: Review of the literature published in scientific journals indexed in PUBMED and Google Scholar, between 2015 and 2021. RESULTS: There is a limited number of publications on this co-occurrence in the international literature and none whatsoever domestically, while those found do not describe specialized intervention models. Body dissatisfaction, with the development of secondary sexual features, emerges as a core aspect of this co-occurrence. Differences are observed in the presentation of EDs in trans men and trans women. There are base risk factors, particularly minority stress, and protective factors, like family support. A model with stages is described and proposed, focused on prevention, particularly for the first signs of body dissatisfaction, with an intervention stage that mainly includes affirmative medical treatment, favoring the reduction of body dissatisfaction; and finally, the last stage monitors achievements and gives support when facing relapses. CONCLUSIONS: Both in the evaluation and intervention, it is important to detect this early, in puberty, to incorporate affirmative medical treatment, to give support for protective and risk factors, without labeling EDs as a comorbid pathology, and to carry out a follow-up on relapses.

A produção científica sobre transtornos alimentares na área da psicologia / Scientific production on eating disorders in psychology / La producción científica sobre trastornos alimentarios en el campo de la psicología

O presente estudo teve como objetivo investigar a produção científica sobre transtornos alimentares na área da psicologia. Foi realizada uma revisão sistemática da literatura nas bases de dados EBSCO, SciELO e PePSIC, tendo como período de busca os anos de 2009 a 2019. A análise qualitativa dos dados foi realizada em duas etapas. Primeiramente, os resumos dos estudos encontrados foram lidos e classificados quanto às características das amostras, às características metodológicas e aos temas investigados. Em um segundo momento, foram selecionados apenas os estudos que abordam possibilidades de intervenções psicológicas em tratamentos focados na anorexia, na bulimia nervosa e no transtorno de compulsão alimentar para uma análise aprofun-dada. Para essa última, os estudos foram lidos na íntegra e classificados com base em duas categorias: 1) Resultados referentes às intervenções com os pacientes; e, 2) Resultados referentes às intervenções com os familiares. Os resultados apresentaram exclusivamente intervenções grupais, seja para os pacientes, seja para seus familiares. Os profissionais da psicologia operam com grupos de apoio, sendo esses uma maneira efetiva para alcançar ressignifica-ções sobre os sentimentos e experiências relativos aos transtornos alimentares. Discute-se a importância de o profissional da psicologia estar preparado para lidar com o tratamento dessa psicopatologia em específico.

The present study aimed to investigate the Brazilian scientific production on eating disorders in Psychology. A systematic literature review was conducted in the EBSCO, SciELO and PePSIC databases with the search period of the 2009 to 2019. Qualitative data analysis was performed in two steps. Firstly, the abstracts of the studies were read and classified according to the characteristics of samples, the methodological characteristics and the investigation themes. In a second moment, only studies addressing the possibility of psychological interventions in anorexia, bulimia nervosa and binge eating disorder were selected for further analysis. For this, the full articles were read and classified based on two categories: 1) Results about interventions with patients, and; 2) Results about interventions with family members. The results showed a predo-minance of group interventions and none individually, either for patients or their families. Psychologists work with support groups, which are an effective way to achieve resignifications about feelings and experiences with eating disorders. The importance of the psychology professional being prepared to deal with the treatment of this specific psychopathology is discussed.

En un segundo momento, se seleccionaron sólo los estudios que abordan posibilidades de intervenciones psicológicas en tratamientos enfocados en la anorexia, la bulimia nerviosa y el trastorno de compulsión alimentaria, para un análisis profundo. Para esto, los estudios se han leído en su totalidad y se han clasificado en dos categorías: 1) Resultados relativos a las intervenciones con pacientes; y, 2) Resultados relativos a las intervenciones con familiares. Los resultados presentaron exclusivamente intervenciones grupales, ya sea para los pacientes o para sus familiares. Los profesionales de la psicología operan con grupos de apoyo, siendo éstos una manera efectiva para lograr resignificaciones sobre los sentimientos y experiencias. Se discute la impor-tancia de que el profesional de la psicología esté preparado para hacer frente al tratamiento de esta psicopatología en específico.

Are Sensitivity to Punishment, Sensitivity to Reward and Effortful Control Transdiagnostic Mechanisms Underlying the Eating Disorder/Obesity Spectrum?

Although it has been postulated that eating disorders (EDs) and obesity form part of a broad spectrum of eating- and weight-related disorders, this has not yet been tested empirically. In the present study, we investigated interindividual differences in sensitivity to punishment, sensitivity to reward, and effortful control along the ED/obesity spectrum in women. We used data on 286 patients with eating disorders (44.6% AN-R, 24.12% AN-BP, and 31.82% BN), 126 healthy controls, and 640 Class II/III obese bariatric patients (32.81% Class II and 67.19% Class III) with and without binge eating. Participants completed the behavioral inhibition and behavioral activation scales, as well as the effortful control scale, to assess sensitivity to punishment and reward and effortful control. Results showed that patients with EDs scored significantly higher on punishment sensitivity (anxiety) compared to healthy controls and Class II/III obese patients; the different groups did not differ significantly on reward sensitivity. Patients with binge eating or compensatory behaviors scored significantly lower on effortful control than patients without binge eating. Differences in temperamental profiles along the ED/obesity spectrum appear continuous and gradual rather than categorical. This implies that it may be meaningful to include emotion regulation and impulse regulation training in the treatment of both EDs and obesity.

Adaptação e validação do Inventário de Desordem Alimentar para o contexto brasileiro / Adaptation and validation of the Eating Disorder Inventory for the Brazilian context / Adaptación y validación del inventario de trastornos alimentarios para el contexto brasileño

O objetivo deste estudo foi adaptar e validar o Inventário de Desordem Alimentar (EDI-3) para o contexto brasileiro. O EDI-3 contém 91 itens e 12 subescalas. Participaram 664 pessoas com idades entre 14 e 51 anos (M = 22,33; DP = 5,63), sendo 71 adolescentes estudantes de ensino médio, 512 adultos universitários e uma amostra clínica composta por 81 participantes. Análises fatoriais confirmatórias indicaram que o Componente de Risco de Transtorno Alimentar (EDRC) apresentou estrutura trifatorial com bons indicadores de ajuste, enquanto o Componente de Desajustamento Psicológico Geral (GPMC) apresentou melhores indicadores no modelo tetrafatorial. A consistência interna mostrou-se adequada para maioria das subescalas. Comparação de grupos apresentou indícios complementares de acurácia no instrumento.

Association between Emotional Eating and Frequency of Unhealthy Food Consumption among Taiwanese Adolescents.

Emotional eating is one factor that increases the consumption of unhealthy food. This study aimed to investigate the association between emotional eating and frequencies of consuming fast food, high-fat snacks, processed meat products, dessert foods, and sugar-sweetened beverages (SSBs) in adolescents. The baseline survey data (2015) from the Taiwan Adolescent to Adult Longitudinal Study (TAALS) were fitted into multivariate logistic regression models adjusted for sex, school type, Body Mass Index (BMI), eating while doing something, nutrition label reading, skipping breakfast, smoking, binge drinking, sedentary lifestyle, physical activity, peer and school support, and parental education level. Among the 18,461 participants (48.5% male and 51.5% female), those exhibiting emotional eating were more likely to consume fast food (Odds ratio (OR) = 2.40, 95% Confidence interval (CI): 2.18-2.64), high-fat snacks (OR = 2.30, 95% CI: 2.12-2.49), processed meat products (OR = 1.92, 95% CI: 1.78-2.08), dessert foods (OR = 2.49, 95% CI: 2.31-2.69), and sugar-sweetened beverages (OR = 1.83, 95% CI: 1.70-1.98). Factors that were positively associated with unhealthy food consumption included eating while doing other activities, binge drinking, smoking, and sedentary lifestyle. Among all the covariates, nutrition label reading was the only factor that was inversely associated with frequent unhealthy food consumption. Sex and school type may moderate the effect of emotional eating on the frequent consumption of specific unhealthy food groups. In conclusion, adolescents with high emotional eating were more likely to report frequent consumption of unhealthy foods in Taiwan. Our findings showed that male participants appeared to consume fast foods, high-fat snacks, processed meat, and SSBs more often and dessert foods less often than females. Future longitudinal studies are recommended for understanding the causal relationship between emotional eating and unhealthy food consumption.

The Development of Feeding and Eating Disorders after Bariatric Surgery: A Systematic Review and Meta-Analysis.

BACKGROUND: Patients in the postoperative period following bariatric surgery are at risk of developing eating disorders. This study aims to analyze the relation between bariatric surgery and the development and recurrence of eating disorders. MATERIAL AND METHODS: A literature review was carried out on 15 November 2020. Fourteen studies that met the eligibility criteria were included for qualitative synthesis, and 7 studies for meta-analysis. RESULTS: The prevalence of eating disorders in the postoperative period was 7.83%, based on the 7 studies in the meta-analysis. Binge eating disorder alone was 3.81%, which was the most significant factor, and addressed in 6 of these studies. CONCLUSION: The investigated studies have significant methodological limitations in assessing the relation between bariatric surgery and eating disorders, since they mostly present data on prevalence.

Introducing Dietary Self-Monitoring to Undergraduate Women via a Calorie Counting App Has No Effect on Mental Health or Health Behaviors: Results From a Randomized Controlled Trial.

BACKGROUND: Strong positive relationships between dietary self-monitoring and eating disorder risk are seen in population-based, observational studies. However, current evidence cannot establish causality. Furthermore, little is known about other mental and behavioral health consequences of dietary self-monitoring among college women, a population vulnerable to eating disorders. OBJECTIVE: To determine if introducing dietary self-monitoring via a popular smartphone app to undergraduate women impacts eating disorder risk, other aspects of mental health, or health behaviors including dietary intake and physical activity. DESIGN: Randomized controlled trial. PARTICIPANTS/SETTING: Undergraduate women who had not engaged in dietary self-monitoring in the past year and who were at low-risk for an eating disorder participated between May and October 2019 (n = 200). INTERVENTION: Participants were randomly assigned to engage in dietary self-monitoring via MyFitnessPal for approximately 1 month or to receive no intervention. MAIN OUTCOME MEASURES: Self-report data on eating disorder risk, other mental health outcomes, and health behaviors were collected at baseline and post-intervention. STATISTICAL ANALYSES PERFORMED: Linear and logistic regressions were utilized to test hypotheses. RESULTS: Adherence to the intervention was high, with participants recording their dietary intake via MyFitnessPal on average 89.1% of days between baseline and post-intervention. Assignment to the intervention was not associated with changes in eating disorder risk, anxiety, depressive symptoms, body satisfaction, quality of life, nutritional intake, physical activity, screen time, or other forms of weight-related self-monitoring (all P > .05). CONCLUSIONS: Among dietary self-monitoring naive undergraduate women with low-risk of an eating disorder, dietary self-monitoring via MyFitnessPal for 1 month did not increase eating disorder risk, impact other aspects of mental health, or alter health behaviors including dietary intake. The null results in our study may be due to the selection of a low-risk sample; future research should explore whether there are populations for whom dietary self-monitoring is contraindicated.

Prevalence and Characteristics of Orthorectic Disorders in Adolescence and Young People: Polish Preliminary Studies.

The aim of this work was to assess orthorectic behaviors among young people and to evaluate their attitudes towards caring for their health. The study was conducted in 2019 on a group of 538 respondents aged 16-35. After analysis, 65 questionnaires were eliminated from further research, and the assessment of orthorectic disorders was performed using a method based on the modified ORTO-15 questionnaire on a group of 473 respondents. A large percentage of them exhibited an increased risk of orthorectic behaviors (32.8), which was higher among women than men (34.7% and 28.2%, respectively). People with higher risks of orthorectic disorders significantly more often reduced their consumption of foods high in fats and sugars. Attitudes of people with orthorectic disorders towards health care proved neutral, with a tendency to be positive. Nutritional behaviors observed in the studied group show some irregularities, which indicates the need for preventive and educational measures aimed at increasing awareness of the role of proper nutrition among young people. The obtained results may be the basis for further research on ON symptoms. One of the major areas of future research would be to create a reliable diagnostic tool which would allow for distinguishing between orthorexia and overdiagnosis.

[Nutritional education protocol in the treatment of eating disorders in the clinical and care settings]. / Protocolo de educación nutricional en el tratamiento de los trastornos de la conducta alimentaria en el ámbito clínico y asistencial.

INTRODUCTION: Nutrition education (NE), as part of the treatment of eating disorders (EDs), plays a crucial role in helping patients to change their food attitudes and routines, lose fears, and recover a healthy eating pattern. All these changes may contribute to improving their nutritional status. However, there is a lack of consensus and standardization concerning the procedures to teach it. This work's objective was to elaborate a consensual protocol for NE implementation in the treatment of EDs to help in decision-making regarding which patients are appropriate candidates to receive NE, the agents (family, school community) and professionals involved, and the areas in the healthcare system that are best suited for implementation. Moreover, it would help in selecting the the topics to be imparted, and in following up treatment progression.

INTRODUCCIÓN: La educación nutricional (EN), dentro del tratamiento de los trastornos de la conducta alimentaria (TCA), juega un papel fundamental ya que contribuye a que el paciente modifique sus actitudes y rutinas en relación con la comida, pierda miedos y restablezca un patrón de alimentación saludable, favoreciendo de este modo su recuperación nutricional. Sin embargo, existe falta de consenso y estandarización acerca de los procedimientos para llevarla a cabo. El objetivo de este trabajo es elaborar un protocolo consensuado de EN en el contexto del tratamiento de los TCA que permita ayudar a la toma de decisiones sobre: los pacientes candidatos a recibirla, los agentes (familia, comunidad escolar) y profesionales implicados, los ámbitos de implementación de la intervención, la información sobre los pacientes que es necesario conocer, los temas, objetivos y contenidos a trabajar, y la necesidad de evaluación de la progresión del paciente y los programas desarrollados.
